Description
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This application is a continuation of application Ser. No.
13/928,644, filed Jun. 27, 2013, which claims the benefit of U.S.
Provisional Application No. 61/666,479, filed on Jun. 29, 2012 and
U.S. Provisional Application No. 61/734,632, filed on Dec. 7, 2012,
each of which is incorporated herein in its entirety.
BACKGROUND
Field of the Invention
[0002] Embodiments of the present invention generally relate to
wound care articles and, more particularly, to wound care gloves,
anklets, knee and elbow supports, masks, skullcaps, finger cots,
and the like, comprising moisture-wicking and/or antimicrobial
elements. Methods of fabricating the articles are also
disclosed.
Description of the Related Art
[0003] Gloves, anklets, finger cots, knee and elbow supports,
masks, skullcaps, and like articles are used to protect the hands,
face, scalp, wrists, knees, and other joints of users. These
articles have also found utility in the medical industry for wound
care following cuts, abrasions, and chemical-, heat- and
flame-caused burns. However, such injuries are often difficult to
dress because joints move and, therefore, any dressing needs to
accommodate this movement while remaining in intimate contact
thereto. Furthermore, such articles can be used at all stages of
care, for example, while in intensive care, emergency rooms, and
outpatient and hospice care. Moreover, burn treatment often
requires multiple changes of dressings.
[0004] Many such articles have synthetic or natural polymeric
coatings to provide substantially impervious properties. Although
impervious properties promote protection against germs, viruses,
and the like, these articles also trap moisture and, in particular,
trap perspiration inside the article. Moreover, during, for
example, burn treatment, skin secretes moisture and exudates.
Gloves and other wound care articles that trap moisture feel clammy
and uncomfortable to the user and allow a septic, unhygienic
environment to form in which microbes prosper. In addition, many
wearable articles are rigid, stiff fabrics and have seams,
imparting even additional stiffness, leading to stress and
irritation during donning, usage, and doffing. Furthermore, skin
sticks to dressings and other wearable articles, such as gloves,
anklets, finger cots, and the like, during healing, which occurs
particularly at joints, such as the knee, knuckles, ankles, elbow,
and other areas where the article most tightly contacts a user's
skin, which poses problems in removing dressings for viewing wounds
or replacing the wound dressing as is often required.
[0005] Therefore, there is a need in the art for anti-microbial
articles that manage moisture and perspiration, are flexible for a
tight and comfortable fit during mobility, don and doff easily, can
optionally be used with substantially cylindrical compression
sleeves, and promote healing by allowing intimate contact of the
article having the antimicrobial with the skin of the wearer
without sticking to or abrading the skin/wound.
SUMMARY
[0006] Embodiments of the invention include an apparatus and
methods for making wearable, easy to don and doff anti-microbial
articles substantially as shown in and/or described in connection
with at least one of the figures, as set forth more completely in
the claims. Various advantages, aspects, and novel features of the

DETAILED DESCRIPTION
[0028] Embodiments of the present invention comprise articles
having a first yarn, to produce a layer that can be knitted with a
second yarn having an antimicrobial agent to form the article, such
as a glove, anklet, wristlet, sock, mask, finger cot, and other
sleeves used to treat burns. The articles further comprise a layer
having a moisture wicking fiber and/or an elastic yarn, and a layer
comprising an antimicrobial agent for the treatment of wounds,
wherein the inner layer does not stick to wounds and the second
yarn promotes the wicking of moisture from one area, such as a
wound, to a second layer and the transport of an antimicrobial
agent to the wounds of a user. The article may be knitted by
conventional knitting processes and may further comprise various
deniers of yarns and gauges, which can be used to increase the
channeling efficiency and distribution of moisture from one area of
the article to other areas and to the outer layer.
[0029] Knitted articles may be seamless and comprise one or more
yarns. In embodiments of the invention, a first layer is an
absorbent, moisture-wicking knitted layer having an antimicrobial
layer for the treatment of wounds and the second layer comprises
cotton, polyesters, nylons, SPANDEX.RTM., and the like and/or any
combination of these yarns, imparting stretch and comfort
properties. In some embodiments, the first layer is an inner layer,
which contacts the skin of the wearer, comprises a hydrophilic yarn
capable of transferring metals, such as silver, gold, or zinc, or
their alloys or combinations of elemental metals and alloys (or
other antimicrobials as discussed below), to a wound of a wearer,
which promotes healing and an antiseptic environment. A second
layer may be disposed on the skin-contacting layer. In some
embodiments, the articles comprise a third, fourth, or fifth layer
disposed on the second layer, each having either or both of,
cotton, polyesters, nylons, SPANDEX.RTM., hydrophilic, and
anti-microbial yarns. Furthermore, embodiments of the invention
comprise cut-and-sewn fabrics.
[0030] In some embodiments, the hydrophilic yarn used is a nylon
yarn, such as nylon 6,6 or Nilit.RTM. AQUARIUS yarn having
irregular cross-sections for exceptional wicking properties. Nylons
promote the transport of moisture from the wound to the outer
layer. In some embodiments of the invention, a nylon yarn is used
as a main yarn, while in other embodiments, nylon yarn may be
plaited into a main yarn. In other embodiments of the invention,
two or more yarns are plaited throughout the article and,
accordingly, the article has two layers throughout the entire
article. The inner and outer yarns may optionally comprise the same
nylon yarn, a different nylon, or a non-nylon yarn. Micro-denier
and multi-filament yarns also promote superior wicking action. Both
the inner layer yarn and the outer layer yarn may be chemically
treated with elemental metals, such as gold, copper, iodine,
silver, or zinc or their alloys, a noble metal-ion, TRIOSYN.RTM.,
triclosan, 2-propanol, quaternary ammonium compounds, n-halamines
or compounds and combinations thereof, for their antimicrobial
properties. Silver-zinc and silver-copper zeolites are also
suitable antimicrobials, as well as other anti-microbials known to
those in the art.
[0031] Hydrophilic yarns allow the transfer of metal ions from the
yarn to the wound or eluent, promoting healing of the wound. Other
suitable antimicrobial agents include, but are not limited to,
polymeric biguanides and quaternary ammonium compounds, such as
chlorhexidine gluconate. The layers of the article may further
comprise padding in one or more areas of the article. Seamless,
knitted articles offer improved fit, comfort, antimicrobial
functionality as well as lower costs. Seamless knitted articles in
accordance with embodiments of the invention also offer articles
that stick to skin less than articles having seams and,
furthermore, provide less friction against the skin of the user.
Non-stick yarns are also contemplated according to embodiments of
the invention. For example, any of the yarns disclosed herein may
be blended with low surface tension yarns, such as modified
polytetrafluoroethylene yarns and polyethylenes.
[0032] FIG. 1 depicts a glove 100 according to embodiments of the
invention. The glove 100 comprises a thumb 102, an index finger
104, a middle finger 106, a ring finger 108, a pinky finger 110, a
cuff 112, and a palm 114, which is knitted or optionally cut and
sewn. The glove 100 may be made several different sizes. Referring
to the reference numerals of FIG. 1, the width 1 of cuff 112 ranges
from approximately four-and-one-half inches to five-and-one-half
inches. The maximum palm width area 2, the maximum width of the
glove 100, before any polymeric coating is disposed thereon, as
discussed below, may range from approximately six-and-one-quarter
inches to eight-and-five-eighths inches. The palm width 3 across
the glove 100 to a crotch 101 of the thumb 102 between the index
finger 104 and thumb 102 may range from approximately
four-and-one-third inches to five-and-five-eighths inches. The
thumb width 4 may range from approximately one inch to
one-and-one-half inches. The index finger width 5 may range from
approximately one inch to one-and-one-half inches. The middle
finger width 6 may range from approximately one inch to
one-and-one-half inches. The ring finger width 7 may range from
approximately one inch to one-and-one-half inches. The pinky finger
width 8 may range from approximately seven-eighths of an inch to
one-and-one-quarter inches. All ranges recited herein are exemplary
and embodiments of the invention admit to other sizes and
dimensions. For example, gloves and other articles can be designed
in similar proportions to fit the limbs and torso of small
children.
[0033] The thumb seam length 10 may range in size from
approximately one-and-one-half inches to two-and-one-half inches.
The index finger seam length 11 (between the index finger 104 and
the thumb 102) ranges from approximately three-and-one-quarter
inches to five-and-one-quarter inches. The index finger seam length
12 (between the index finger 104 and middle finger 106) may range
from approximately two inches to three-and-one-quarter inches. The
index finger length 13 (as measured from the tip of the finger 104
to reference line 103) ranges from approximately
three-and-three-eighths inches to five-and-one-quarter inches. The
middle finger seam length 14 and 15 may range from approximately
two-and-three-eighths inches to three-and-five-eighths inches. The
middle finger length 16 may range from approximately four inches to
five-and-three-quarter inches. The ring finger seam length 17
(between the ring finger 108 and middle finger 106) ranges from
approximately two inches to three-and-three-eighths inches. The
ring finger seam length 18 (between the ring finger 108 and pinky
finger 110) ranges from approximately two-and-one-quarter inches to
three-and-five-eighths inches. The ring finger length 19 may range
from approximately three-and-three-eighths inches to
five-and-one-quarter inches. The pinky finger seam length 20
(between the ring finger 108 and pinky finger 110) may range from
approximately one-and-one-half inches to two-and-seven-eighths
inches. The pinky finger seam length 21 ranges from approximately
two inches to three-and-seven-eighths inches. The pinky finger
length 22 may range from approximately two-and-three-eighths inches
to four-and-one-quarter inches.
[0034] The cuff width 1 may optionally comprise a width that is the
same size, slightly smaller, or slightly larger than the width of
the glove (as measured across the thumb area 2). Cuffs that do not
significantly taper or neck down from the hand or foot to fit the
size of the wrist or ankle (as is common for gloves and anklets and
articles for other body parts) will be larger and allow ease of
donning and doffing. Each of the fingers, 102, 104, 106, 108, and
110 can optionally be capless, wherein the caps of the fingers are
either not knitted or are removed, so that the fingertips of the
wearer are exposed. Embodiments of the invention may further
comprise wherein the articles are knitted in accordance with the
Knitted Variable Stitch Design (KVSD) and/or three-dimensional,
Automatic-Knit-Liner technologies as is disclosed in
commonly-assigned U.S. Pat. Nos. 6,962,064; 7,213,419; 7,246,509;
7,434,422; and 7,555,921, each of which is hereby incorporated by
reference in its entirety.
[0035] Articles in accordance with embodiments of the invention can
be knit with a knitting machine according to instructions provided
via computer programming. Double-layered zones for knitted articles
may be formed using a variable plaiting process, increasing the
stretch in key flex areas of the gloves by altering the number of
plaited courses in each section, such as the knuckles or the crotch
between the index finger and thumb. For example, stretchable
multi-layer functional zones are formed by plaiting a second yarn,
such as SPANDEX.RTM. or LYCRA.RTM., every fourth course in areas of
low flex of the outer layer. Furthermore, the flex in some areas
may be increased by adding a different yarn every eighth course in
sections where no second yarn was present. The use of every 4th and
8th course in the plaiting structure is for illustrative purposes
only. The plaiting structure can range from every other course to
every 9th course using machines, such as, but not limited to,
models SFG-I, NSFG, and SWG, manufactured by Shima Seiki Mfg.,
Ltd.
[0036] The properties of knitted articles in embodiments of the
invention can be varied without the addition of different yarns.
For example, varying the stitch dimensions, such as yarn tension
and needle depth, can produce articles having different levels of
stretchability. The tension of the yarn may be varied by adjusting
the tension of the yarn between a pinch roller and a knitting head
by computer control of a knitting machine, as is disclosed in
commonly-assigned U.S. Pat. No. 7,434,422. A layer that is knitted
tighter will have less stretchability. Varying the depth of
penetration of the knitting needle into the article, and by casting
off or picking up additional stitches in a knitted course, can also
affect stretchability. A shallower needle penetration produces an
article that is tighter and more difficult to stretch.
[0037] FIG. 2 depicts the glove 100 having a slit cuff and coating
disposed thereon, according to embodiments of the invention. In
some embodiments, glove 100 includes a slit cuff 206 located on the
pinky side of the glove 100, although other areas may have a slit,
such as the thumb side. The glove 100, whether knitted or
cut-and-sewn, may have one or more slits 206 along a longitudinal
(as shown) or latitudinal axis, and along all or part of the
article allowing the article to open and close in a clamshell-like
manner for ease of donning and doffing over burned or wounded
limbs, feet, hands, and the like. The slit 206 may traverse part of
the article or the entire article. Articles in accordance with this
principle may be opened and closed using non-permanent attachments,
such as a strap and clasp (not shown), hook and loop fasteners 204,
such as VELCRO.RTM., and the like. In this context, the term
non-permanent indicates the feature of being able to open and close
the article multiple times without loss of attach-ability. As
shown, the slit 206 traverses the side of the glove 100 on the cuff
102, exposing the side of the wearer's wrist. As will be discussed
below, other embodiments comprise slits in different areas of a
glove.
[0038] The glove 100, as shown in FIG. 2, may optionally comprise a
polymeric coating 202. The polymeric coating 202 may be comprised
of a natural latex, such as guayule or polyisoprene, a synthetic
latex, such as carboxylated acrylonitrile butadiene,
non-carboxylated acrylonitrile butadiene, butyl latex,
polychloroprene, nitriles, polyurethane, and the like latex,
polymeric, or elastomeric compositions, or blends thereof. The
coating 202 may be formed on the glove 100 using the dip processes
as described in commonly assigned U.S. Pat. No. 7,814,571, and U.S.
patent application Ser. No. 12/769,829, each of which is
incorporated herein by reference in its entirety. In FIG. 2, a palm
dip is shown. The coating 202 optionally comprises a knuckle dip,
finger dip, a three-quarters dip, and the like as needed for
specific applications. Furthermore, before dipping in the polymeric
coating, the gloves may be dipped in a coagulant, such as calcium
nitrate or other coagulants known to those in the art, to
destabilize the latex, promote gelling, and prevent strikethrough
of the polymeric coating.
[0039] FIG. 3 depicts a glove 300 according to at least one
embodiment of the invention. In some embodiments, gloves and other
articles in accordance with embodiments of the invention are
knitted and subsequently inverted. FIG. 3 shows knitted courses on
the thumb 102, index finger 104, middle finger 106, ring finger
108, pinky finger 110, and palm 114, which are shown as wavy lines,
running perpendicular to the longitudinal length of the outside of
the glove 300. The courses on the inside of the glove run parallel
to the longitudinal length of the glove 300, resulting in the ease
of donning and doffing because of lessened friction against the
wearer's skin as discussed below. The combination of the use of
stretchable yarns in the outer layer, such as SPANDEX.RTM. or
LYCRA.RTM., which may be knitted loosely as discussed above despite
a snug fit with the afflicted body part, the disposition of the
courses as described below, and the use of a clamshell like opening
detachably adhered with fasteners, produces a glove allowing a snug
fit with a minimal amount of irritation to the skin of the user or
patient.
[0040] FIG. 4 depicts a close-up view 410 of a knitted plaited
fabric of the finger 106 of FIG. 3, in accordance with embodiments
of the invention. The layer 402, which may be the inner layer, of
the knitted plaited fabric of the finger 106 is shown in shading,
which is the layer that contacts the skin of the wearer. As
discussed above, the layer 402 comprises a hydrophilic yarn, such
as a nylon, that is coated with an agent having antimicrobial
activity, as discussed below. In some embodiments, the inner layer
402 comprises a nylon 6 or nylon 6,6 yarn that is coated with
silver or another metal. The layer 404, which may be an outer
layer, comprises cotton, polyesters, nylons, SPANDEX.RTM.,
LYCRA.RTM., and the like and/or any combination of these yarns. As
shown, the layer 402 may be seamlessly plaited throughout the
article. The courses of knitted fabrics create interstices between
stitches of yarn. For example, the wicking channels 408 of the
layer 404 run along an axis perpendicular to the longitudinal axis
of the glove or, in other words, are horizontally as depicted. The
wicking channels 406 of the layer 402, the side contacting the skin
of a user, run along an axis parallel to the longitudinal axis of
finger 106 of glove 300. When the wicking channels 406 are so
situated, internal to a glove, the friction is lessened against the
skin of a wearer of an article, maximizing the amount of stretching
possible to accommodate swelling near a wound. Furthermore, yarns
having irregular or non-circular cross sections can enhance a
wicking action of liquids through spaces between yarns.
[0041] The inner plaited yarns will typically be lighter than the
outer yarn, ranging in size from 70-1000 denier and needle gauges
ranging from 10-18. Plaiting the inner antimicrobial layer in only
certain areas, for example, the palm, the backhand, or the fingers,
is also contemplated and reduces the overall cost of the glove
because of the expense of the antimicrobial. The inner layer 402
may comprise a hydrophilic yarn, such as nylon 6,6, which contacts
the skin of the wearer, promoting the wicking of moisture away from
the skin, and is treated, such as by coating or other processes,
with an antimicrobial agent, such as silver, to promote the
transport of silver or silver ions from the yarn of the glove to
the wound.
[0042] FIG. 5 depicts a glove having a highly-wicking yarn and
moisture reservoir, according to embodiments of the invention.
Layer 500 comprises a yarn that is made from a highly-wicking
fiber, such as a nylon 6,6, marketed under the name Nilit.RTM.
AQUARIUS by Nilit, Inc. of Martinsville, Va., the highly-wicking
features of which are disclosed below. Other appropriate
highly-wicking yarns include STA-COOL.RTM. polyester, ringspun
hydrophilic polyester HYDROTEC.RTM., or DRYENERGY.RTM.
polyester/cotton and may further comprise any shape for the
treatment of a limb or body part, such as a leg, arm, knee, ankle,
head, waist, and the like. Micro-denier, multi-filament yarns, and
yarns having non-circular, irregular cross-sections are
particularly effective at wicking moisture away from one area, such
as a wound, to other areas.
[0043] The layer 500 optionally comprises an absorbent material
element 530, which is a water-scavenging absorbent reservoir. The
absorbent material element 530, a super absorbent material, may be
attached to a surface of the layer 500, desirably on or near back
hand area and/or cuff area of the layer 500. The absorbent material
element 530 can be attached to the layer 500 by stitching, a
thermoplastic adhesive, glue, other suitable attachments, and the
like. The yarn of the layer 500 is fluidly coupled to the absorbent
material element 530 to facilitate wicking of perspiration or other
fluids from one or more locations, such as indicated by directional
arrows 502, 504, 506, 508, 510, and 512 of the glove to at least
one absorbent material element 530. After the absorbent material
element 530 is adhered to the layer 500, layer 500 may be placed on
a former of a desired shape and coated with a polymeric coating as
discussed above. Embodiments of the invention further comprise
wherein the absorbent material element 530 is disposed or adhered
on the palm or near or along the fingers or finger crotches.
[0044] The perspiration and moisture wicking properties may also be
achieved as disclosed in commonly assigned U.S. Provisional Appl.
Ser. No. 61/571,569, and U.S. patent application Ser. No.
13/538,368, which are incorporated herein by reference in entirety.
This technology includes a super absorbent material comprised of an
electrospun polyurethane and bound acrylate. One such super
absorbent material is marketed as SNS Nanosorb.RTM. 28. SNS
Nanosorb.RTM. 28 has a higher affinity for water compared with the
nylon 6,6 of the inner knitted layer. The super absorbent material
pulls in moisture wicked to it by the nylon yarn, which the super
absorbent material subsequently pulls into its internal matrix.
Such moisture movement leaves the nylon of the inner knitted layer
dry, keeping the moisture away from a user's skin. Different
thicknesses of the super absorbent material may be employed.
Moreover, the super absorbent material can be used, in lieu of
additional padding, to protect body parts from inadvertent bangs
and bumps. Moisture absorption is also enhanced, in some
embodiments of the invention, by the inclusion of poly-acrylates,
polyurethanes, polyvinyl alcohol, hydrogels, and other hydrophilic
materials.
[0045] Other embodiments of the invention may position reservoirs
in various locations and have various shapes and thicknesses to
promote comfort and/or absorbency. The backhand area and cuff area
are good choices for locations for the reservoir because these
areas see little strain and do not contact the skin of the user as
tightly. In other words, moisture is removed from the palm and
finger areas, which have relatively high concentrations of
perspiration and are high strain areas, where the glove most
tightly contacts the skin of the user during use, and is channeled
to areas where there is little contact with skin.
[0046] The highly-wicking yarn of the layer 500 is capable of
directing the moisture toward the cuff and back hand area having
the absorbent material element, which draws moisture inward and
therefore acts as a reservoir. By channeling the moisture away from
the palm and fingers and to the center of the absorbent material
element, a wet or clammy feeling is avoided, promoting hygiene and
comfort. Moreover, the efficient and high transfer of the
antimicrobial agent to the wounded skin of a patient promotes
healing of the skin. In some embodiments of the invention, the
absorbent material element 530 is on the cuff, which is not covered
by the polymeric coating 202, allowing moisture to be evaporated
from the absorbent material. Moisture may also be directed to other
areas, such as to a wound instead of away from the wound. For
example, skin conditions and creams, as well as other medicaments
and medicines.
[0047] FIG. 6 depicts a left-hand glove 600, having conduits for
accommodating resilient members, according to embodiments of the
invention. The glove 600, which shows the back hand of the glove,
includes a thumb 602 and fingers 604, 606, 608, and 610. Any or all
of the thumb 602 and fingers 604, 606, 608, and 610 further
comprise a conduit 612, which is capable of receiving a resilient
member 614 for immobilizing one or more fingers or providing
resistance for strengthening exercises. In some embodiments, the
resilient member 614 comprises a compliant material and profile to
promote hand strengthening. For example, a compliant plastic having
a thin, flat profile, while providing resistance to flexing,
nonetheless allows a wearer to flex all fingers. Accordingly, the
strength of a weakened hand, for instance, after an accident, can
be improved. As the hand of the wearer becomes stronger, the
resilient member 614 can be changed to a stiffer material to
provide additional resistance, allowing even greater strengthening
to occur.
[0048] For some situations, such as an acute injury, for example, a
burn or broken finger, it may behoove the wearer to have one or
more knuckles or fingers immobilized. Therefore, in some
embodiments, the resilient member 614 is made of, for example,
steel, preventing the wearer from bending the fingers. In some
embodiments, the conduit 612 is knitted into glove 600. The conduit
612 may traverse all of a finger or only part, for example, only
one or two knuckles, such as is depicted in the finger 606.
Alternatively, the length of the conduit 612 may extend into the
backhand area 616, such as is depicted on the thumb 602 and finger
604. Also, the glove 600 may comprise truncated fingers, for
example, open-ended fingers and thumbs, as is discussed below, so
that the fingers of the wearer are uncovered. Furthermore, the
conduit 612 is capable of receiving resilient member 614, for
example, through a conduit opening 613. The conduit 612 may also be
open for receiving resilient member on the distal end (not shown)
of the thumb 602 or fingers 604, 606, 608, 610.
[0049] The resilient member 614 may be of variable thicknesses,
widths, lengths, and profiles, for example, circular, square,
rectangular, flat, and the like. Also, the resilient member 614 may
comprise many different materials, for example, compliant plastics,
such as polyethylene, or polypropylene, stiffer plastics, such as
acrylonitrile-butadiene-styrene (ABS) or nylons, or very stiff,
and/or impact-resistant plastics, such as polycarbonate or
polyetherimide, and the like. Rubber materials, such as
thermoplastic elastomers (TPE) and vulcanizates (TPV), can also be
used where flexibility is desirable. In some embodiments, the
resilient member 614 made of TPE or TPV, may be sewn into glove
600. The resilient member 614 also comprises metals, such as
aluminum, steel, titanium, silver, silver alloys, zinc, zinc
alloys, and the like. In some embodiments of the invention, silver
and/or zinc ions, released from the resilient member, migrate, via
an eluent or perspiration, to the wound, promoting healing. In some
embodiments of the invention, the conduits 612 can accommodate
electrical wires, irrigation, lighting, and mechanical pulleys, to
aid in healing, movement, and post treatment. For example, the
conduits 612 may be knitted of a electrically conductive yarn. In
some embodiments, the conduits 612 extend from the end of the
fingertips to the cuff area, where electrical connectors and power
can be added to deliver electricity to wounds, promoting
healing.
[0050] FIG. 7 depicts a perspective view of the palm side of a
right-handed glove 700, in accordance with embodiments of the
invention. The glove 700 includes the thumb stall 702 and finger
stalls 704, 706, 708, and 710. In some embodiments, the glove 700,
as shown, has truncated thumb and finger stalls so that the
fingertips of the wearer are not enclosed within the glove 700.
Also included in the glove 700 are closure flaps 712, 714, and 716,
which comprise hooks that mate with the corresponding members 718,
720, and 722 respectively to close a slit 740. In some embodiments,
the hooks are VELCRO.RTM. hooks, and, in some embodiments, the
hooks engage VELCRO.RTM. loops on the corresponding members 718,
720, and 722 to releasably close the slit 740. The slit 740, and
VELCRO.RTM. closure flaps, can be on the palm or back of the hand,
fingers, or thumb areas. VELCRO.RTM. closure flaps 712, 714, and
716 may adhere to the corresponding members as a single piece or,
alternatively, be split in one or more places, such as at slots 724
and 726, so that not all closure flaps be opened to view the hand.
In some embodiments, the finger stalls can be made to any length
and cut shorter by an attending healthcare worker to better fit the
patient. Moreover, in some embodiments, VELCRO.RTM. members 718,
720, and 722 are omitted and the hooks of VELCRO.RTM. closure flaps
712, 714, and 716 engage directly with the cut-and-sewn fabric or
loops of a knitted article to releasably close the article. In some
embodiments of the invention, the glove 700, comprising slit 740,
may be cut-and-sewn or knitted so that the glove 700 can fit either
a left-hand or a right-hand, i.e., be ambidextrous.
[0051] FIG. 8 depicts a perspective view of the backhand side of a
right-handed glove 700, in accordance with embodiments of the
invention. In FIG. 8, the glove 700 further comprises padding 728.
The padding 728 may be a fabric, such as cotton, or a puncture-
and/or impact-resistant material, such as a plastic, rubber, or
metal. In some embodiments of the invention, the padding 728 is
stitched or knitted directly onto the backhand of the glove 700,
and may be plaited into the glove 700 or knitted into the glove
seamlessly. In other embodiments, it may be adhered in other
manners, such as by a padding that is cut and sewn onto the back
hand area. In yet other embodiments, the glove 700 comprises a
pocket 730 (shown partially by hidden lines). The pocket 730
includes an opening 732, which is capable of accommodating padding
placed into it. In some embodiments, the glove 700 includes having
padding 728 knitted directly within the glove 700 as well as having
the pocket 730 knitted within the glove 700, allowing for double
the amount of padding to be present. In some embodiments, the
padding 728 could be soft for protection or hard to help hold a
desired hand shape or curvature of the hand for therapy
reasons.
[0052] FIG. 9 depicts removable inserts 902 and a cut-and-sewn
glove in accordance with some embodiments of the invention. The
removable insert 902 is a substantially conical or cylindrical
member. The removable insert 902 may be made of any suitable smooth
material, for example, plastics, metals, paper, or glass. The
removable insert 902 may be of many sizes, and is approximately
larger than the finger upon which it will be placed. The removable
insert 902 is placed over the fingers and thumb of a patient to
protect and minimize abrasion of the glove on the wound surface,
which may be painful to the patient and further irritate already
damaged skin. The glove 700 is then placed over the hand, after
which the removable inserts 902 are removed. The removable insert
902 may also be used with finger cots, as discussed below. In
particular, finger cots having two open ends and having closures,
such as a drawstring and/or hook-and-loop closures, such as
VELCRO.RTM., or gloves or other wound care articles having closures
allow the closure to be tightened at different tensions before the
removable insert 902 is removed, allowing custom tightening.
[0053] FIG. 10A depicts a finger cot 1000 in accordance with
embodiments of the invention. The finger cot 1000, which can be
knitted of a single or multiple yarns as discussed above, including
a antimicrobial yarn, includes the finger covering 1002 and the
closure flaps 1020, 1022, and 1024, which comprise hook and loop
fasteners, such as VELCRO.RTM. strips 1004, 1006, and 1008, which
mate with the corresponding VELCRO.RTM. members 1010, 1012, and
1014 respectively. VELCRO.RTM. closure flaps 1004, 1006, and 1008
may adhere to the corresponding members 1010, 1012, and 1014 as a
single piece or, alternatively, be split in one or more places,
such as at slots 1016 and 1018, so that each closure flap moves
independently of the others. As discussed above, the hooks portion
of the VELCRO.RTM. may be omitted, allowing the VELCRO.RTM. closure
flaps 1004, 1006, and 1008 having hooks to engage and releasbly
close the closure flaps 1004, 1006, and 1008 directly.
[0054] The finger cot 1000 can be used on the tips of fingers and
thumb with, for example, the glove 700, or without glove 700. The
finger cot 1000 may be placed over the tip of a finger, for
example, so that it is as long as one knuckle of the finger.
Alternatively, the finger cot 1000 may be as long as the entire
finger of the wearer, extending to the palm and backhand areas of
the wearer's hand. The finger cots 1000 may be cut and sewn and
comprising any suitable yarn. Alternatively, the finger cots 1000
may be knitted from any suitable yarn. In some embodiments, the
finger cots 1000 are knitted using moisture control yarns as
discussed above. Moreover, the finger cots 1000 can be designed to
treat burns, injuries, or other conditions sustained on toes.
[0055] FIG. 10B depicts a finger cot 1050 having a longitudinal
closure in accordance with some embodiments of the invention. The
finger cot 1050 has a closed end at tip 1054. A closure 1052, which
may be a VELCRO.RTM. closure, runs along the longitudinal axis of
the finger cot 1050 on the back of the finger. The closure 1052 may
optionally be placed on the palm side of the finger or either side
of the finger (not shown).
[0056] FIG. 10C depicts an open-ended finger cot 1060 having a
longitudinal closure in accordance with some embodiments of the
invention. The finger cot 1060 has an open end at a tip 1064,
terminating at a ring 1066. A closure 1062, which may be a
VELCRO.RTM. closure, runs along the longitudinal axis of the finger
cot 1060 on the back of the finger. The closure 1062 may also
optionally be placed on the palm side of the finger or either side
of the finger. As discussed above, the finger cot 1060, because it
is open ended, may be used with a removable insert, as discussed
above, to prevent further injury to a wound when donning and
doffing the finger cot 1060 or to custom tighten the closure 1062
of the finger cot 1060, allowing the removable insert to be removed
after the closure is tightened.
[0057] FIG. 11 depicts a side view of a wound care article 1100 for
larger joints in accordance with some embodiments of the invention.
The wound care article 1100 can be used, for example, for a knee or
elbow. The wound care article 1100 may be knitted or cut-and-sewn
from a knitted, woven or non-woven fabric, in accordance with
embodiments of the invention, and comprising yarns, super absorbent
materials, VELCRO.RTM. closure flaps (not shown), and other
features, such as releasably closable slits as discussed herein
with respect to other embodiments of the invention. Moreover, the
wound care article 1100 may be turned inside out so that the
knitted courses run along the longitudinal axis of the article, so
that during donning and doffing, less friction is imparted to the
wearer as discussed above. The wound care article 1100 further
comprises rings 1102, which maintain the article in place around
the joint of the wearer, for example, an elbow, knee, shoulder,
waist, hip, and the like. The wound care article 1100 further
comprises a cut out 1104, allowing the tip of an elbow or knee cap
to extend therethrough. The cut out 1104 therefore allows the limb
of the wearer to be impacted less during bending or stretching.
[0058] FIG. 12 depicts a perspective view of a wound care article
1200 in accordance with embodiments of the invention. The wound
care article 1200 can be used, for example, for receiving an ankle
or wrist. The wound care article 1200 is knitted or woven fabric,
in accordance with embodiments of the invention. Moreover, wound
care article 1200 may be turned inside out so that the knitted
courses run along the longitudinal axis of the article, so that
during donning and doffing, less friction is imparted to the
wearer. The wound care article 1200 further comprises rings 1202,
which may be knitted seamlessly using an elastic yarn, such as
SPANDEX.RTM. or LYCRA.RTM. or a blend of a yarn having an elastic
yarn, to maintain the article in place around the joint of the
wearer, for example, an elbow, knee, shoulder, waist, hip, and the
like.
[0059] The wound care article 1200 may further comprise a cut out
(not shown) as discussed above, to allow, for example, a heel to
extend therethrough. The wound care article 1200 may have a
straight orientation while at rest, for example, having a straight
edge 1204. Alternatively, the edge of the wound care article 1200
may be biased in a bent configuration (not shown). The wound care
article 1200 further comprises elastic regions 1206, which provide
a better fit to a body part and attenuate stretching of the wound
care article in other areas, resulting in less movement and less
friction. Less movement and friction in other areas, which might be
impacted by burns or other injuries, allows for additional healing
without being irritated or stressed by the movement.
[0060] FIG. 13 depicts a wound care mask 1300 in accordance with
embodiments of the invention. The wound care mask 1300, as in other
embodiments of the invention disclosed herein, comprises a knitted
or woven outer layer that is an absorbent, moisture-wicking knitted
layer and an inner layer that is an antimicrobial layer for the
treatment of wounds. The outer layer may comprise cotton,
polyesters, nylons, SPANDEX.RTM., and the like and/or any
combination of these yarns. The inner layer, which contacts the
skin of the wearer, comprises a hydrophilic yarn capable of
transferring metals, such as silver, gold, or zinc, or their alloys
or combinations of elemental metals and alloys to a wound of a
wearer, which promotes healing and an antiseptic environment. The
inner layer also comprises moisture-wicking yarns capable of
transferring water, moisture, and eluent away from the skin.
[0061] The wound care mask 1300 comprises a single part, two parts,
or two or more parts releasably attached to one another.
Irrespective of the number of parts comprising the wound care mask
1300, the wound care mask 1300 comprises closures or hook-and-loop
fasteners 1310 and 1316, such as VELCRO.RTM., which may overlapped
to attach parts of the mask 1300. The closures or fasteners 1310
and 1316 may be disposed on wound care mask 1300 along an axis 1322
from the front of the mask 1302 to the back 1304, from the left
side of the head to the right side of the head along axis 1320, or
along both axes 1320 and 1322. The wound care mask 1300 comprises
cutouts 1306, 1307, 1308, and 1312. For example, the cut out 1306
accommodates the nose of a wearer; the cut out 1307 accommodates
the mouth of a wearer; the cut outs 1308 accommodate the eyes of a
wearer; and the cut outs 1312 and 1314 accommodate the ears of a
wearer. In embodiments of the invention, the mask has no cutouts.
Attending healthcare personnel can take such a mask and make
cutouts as needed for a specific person or injury. For example, if
a nose, ear, or chin was burned badly, it would be a benefit to
have that injury covered by the mask and without a secondary
dressing. Moreover, this allows a one-size, fits-all mask. For
example, the size and location of features varies from person to
person. Eyes may be set further apart, the size of the nose and
ears may different, etc., allowing healthcare personnel to make the
cuts in the mask ensures a mask specific to the needs of the
patient.
[0062] The width of the closures 1310 and 1316 can be varied to
allow for a tighter or looser fit or to accommodate several sizes.
For example, where the lateral width of the closures 1310 and 1316
are each approximately one inch wide, the size of the mark may be
varied by nearly two inches per side. Also, because the wound care
mask 1300 is made of yarn, it may be stretched tightly over the
head of a wearer, creating compression. As discussed above, the
loops of the VELCRO.RTM. or other fasteners can be omitted and the
loops of the VELCRO.RTM. allowed to engage the fabric.
[0063] Outer dressings, which are placed over articles in
accordance with embodiments of the invention, are further
contemplated herein. Outer dressings are placed over the inner
article, the skin-contacting article. The inner article can remain
on the wound, for example a burn for an extended period of time,
while the outer dressing might be changed every day. A burn patient
can self-dress a wound easily and effectively once they were sent
home from a hospital. As discussed below, this approach could be
applied to gloves, finger cots, face masks and others articles.
[0064] FIG. 14A depicts outer dressing 1400 in accordance with
embodiments of the invention. The outer dressing 1400 is a dressing
for use with a glove. It may be a knitted article or a woven
fabric, substantially similar to articles disclosed herein,
including the incorporation of silver, silver alloys, or other
metals in yarns for anti-microbial effects. In some embodiments,
the outer dressing 1400 is a 10-18 gauge knit. In some embodiments,
it is a 13 gauge knit. Where a denser outer dressing is desirable,
such as to absorb greater amounts of moisture, embodiments of the
invention comprise an 18 gauge knit. In some embodiments, the yarn
used to manufacture the skin-contacting article is a silver-coated
nylon 6,6 yarn, such as the X-Static.RTM. yarn manufactured by
Noble Biomaterials of Scranton, Pa. Alternatively, the
skin-contacting article comprises a fabric containing an
anti-microbial manufactured by lftna, Inc. of Ontario, Canada. In
some embodiments of the invention, the outerdressing 1400 is a
bleached cotton overarticle, releasably placed over the
skin-contacting article, and comprises an outer dressing for an
anklet, sock, glove, mask, finger cot, sleeve, compression sleeve,
elbow support, or knee support and the like.
[0065] The outer dressing 1400 comprises a yarn such as a rayon
and/or cotton blend, where the cotton offers provides moisture
absorption and the rayon is lubricious so that the outer dressing
slides easily over the primary article. Yarns used to make the
outer dressing 1400 could be a composite yarn used to make a single
seamless layer. Alternatively, the outer dressing 1400 comprises a
multi-layer having a main yarn and a plaited yarn. In such
embodiments, the rayon layer may be on an inner layer and the
cotton on an outer layer (not shown). The knit or woven fabric
further comprises a highly elastic yarn, such as SPANDEX.RTM. or
LYCRA.RTM., so that, when the outer dressing is stretched during
use, it clamps onto the primary article, i.e., skin-contacting
article, in this embodiment, a glove, which holds the glove in
place and tight to the skin.
[0066] The outer dressing 1400 may be a two-piece construction
comprising a seam 1402. The seam 1402 further comprises VELCRO.RTM.
fasteners as discussed herein. For embodiments of the invention in
which outer dressing comprises two pieces, outer dressing 1400 can
be placed over a glove and secured tightly or loosely with the
VELCRO.RTM. fasteners at the seam 1402. The outer dressing 1400
further comprises fasteners along the backhand area 1406, such as
VELCRO.RTM. fasteners 1404 (closed, as shown). In some embodiments,
fasteners may alternatively or additionally be disposed along the
palm area (not shown). This allows one to view the wound without
having to remove the outer dressing 1400 entirely. Also, the outer
dressing 1400 comprises truncated fingertips 1408 or, in some
embodiments, where the fingertips are present (not shown).
[0067] FIG. 14B depicts outer dressing 1450 in accordance with
embodiments of the invention. The outer dressing 1450 is for use
with a mask as discussed above. The outer dressing 1450 comprises
all the benefits of the outer dressing 1400, including a two-piece
construction, having two halves, which are adhered to each other
releasably with fasteners, such as VELCRO.RTM.. As shown, the outer
dressing 1450 has front half 1452 covering the inner mask 1454,
which is a mask substantially as described above. The outer
dressing 1450 may comprise the hooks of VELCRO.RTM. fasteners on
one half, such as the front half 1452 while having the loops of the
VELCRO.RTM. fasteners on the other half (not shown). Alternatively,
as discussed above, the VELCRO.RTM. loops may be omitted. For
example, where the front half 1452 has fasteners having hooks on an
inside surface, the VELCRO.RTM. hooks may engage the yarn of the
mask 1454 directly. Additional outer dressings may also be made in
accordance with embodiments of the present invention, such as for
articles disclosed herein for the fingers, knee, ankle, and the
like.
[0068] FIG. 15A depicts the palm side of right-handed glove 1500,
in accordance with embodiments of the invention. The glove 1500
includes a thumb flap 1502 and finger flaps 1504, 1506, 1508, 1510,
and optionally a slit 1514. Any or all of thumb flap 1502, and
finger flaps 1504, 1506, 1508, 1510, at their distal end 1512,
comprise hook and loop fasteners. Although thumb flap 1502 and
finger flaps 1504, 1506, 1508, 1510 may be wrapped around the
fingers of a wearer, thus lessening the stress of donning and
doffing, these can still be used in conjunction with removable
insert 902, as discussed above.
[0069] In some embodiments, the glove 1500 comprises a knitted or
woven structure, substantially similar to articles disclosed
herein, including the incorporation of silver, silver alloys, or
other metals in yarns for anti-microbial effects. In some
embodiments of the invention, the glove 1500 is a woven and cut and
sewn structure. The glove 1500 comprises two halves that are cut
and sown together to form glove 1500, as discussed below. The glove
1500 further comprises hooks and loops, or optionally VELCRO.RTM.
closures, on the palm or back of the hand to releasably close any
slit within the glove. The hook and loops fasteners, or VELCRO.RTM.
closures 720 and 722, may adhere to the corresponding members as a
single piece or, alternatively, be split in one or more places so
that not all closure flaps be opened to view the hand, as discussed
above.
[0070] FIG. 15B depicts the backhand side of a right-handed glove
liner 1520, in accordance with embodiments of the invention. For
example, the glove half 1520 and may be sewn with another glove
half 1520 to form the glove 1500. The glove half 1520 comprises
thumb member 1522 and finger members 1524, 1526, 1528, and
1530.
[0071] FIG. 15C depicts the palm side of a right-handed liner 1550,
in accordance with embodiments of the invention. Glove half 1550
comprises a thumb member 1552, and finger members 1554, 1556, 1558,
and 1560 and optionally comprises a slit 1514. The thumb member
1552, and finger members 1554, 1556, 1558, and 1560 are longer than
the corresponding thumb member 1522 finger members 1524, 1526,
1528, and 1530 of glove half 1520 as discussed above. The glove
half 1550 can be sewn to glove half 1520 to create the glove 1500.
The thumb members 1552, and finger members 1554, 1556, 1558, and
1560 are longer and may be wrapped around the fingers and thumb of
the wearer without subjecting the wearer to the frictional forces
of donning, which cause further painful abrasions and/or loss of
skin tissue following a burn, as would be encountered with a
conventional glove.
[0072] In some embodiments of the invention, the glove 1500 may be
knitted comprising the thumb 1522 and finger members 1524, 1526,
1528, and 1530. Whether knitted or cut and sewn, glove 1500 further
comprises the closures 1512 adhered thereto at a terminal end of
thumb flaps and/or finger flaps. The closures 1512 may be, for
example, hooks that engage loops on a corresponding area to hold
the flap closed. The loops may be adhered to the flap or the loops
may be the loops of a knitted article (not shown). In some
embodiments, the hook and loops are VELCRO.RTM. closures.
VELCRO.RTM. closures 1512 may also comprise hooks that engage the
knitted or woven fabric to releasably close the thumb flap or
finger flaps.
[0073] In some embodiments, because the thumb member 1552, and
finger members 1554, 1556, 1558, and 1560 are longer, these can be
made cut shorter by an attending healthcare worker to better fit
the patient. In some embodiments of the invention, the glove 700,
comprising slit 740, may be cut-and-sewn or knitted so that glove
700 can fit either a left-hand or a right-hand, i.e., be
ambidextrous.
[0074] Embodiments of the invention, discussed herein, are directed
towards gloves, socks, masks, fingercots, and the like. It is to be
further understood that other articles for wound care on other
parts of the body are contemplated herein. For example, articles
for other parts of the legs, torso, and the like are possible and
within embodiments of the invention. Other articles in accordance
with embodiments of the invention may be designed and placed over
joints, such as the elbow, knee, ankle, hip, shoulder, and the
like, which contain all features of embodiments of the invention.
Moreover, an article for a joint, for example, a glove extending
past the wrist, may be combined with a substantially cylindrical
compression sleeve, as could be manufactured by knitting the two
components together in a single knitting operation, to form an
article that addresses more than one body part. Furthermore, the
combination of a glove having a compression sleeve can be made
purposely long. Subsequently, the article can be cut shorter by an
attending healthcare worker to better fit the patient or to cover
only as much of the impacted body part. Embodiments of the
invention also include a compression sleeve attached or knitted
integrally with an article for an ankle or knee extending to the
calf or to the thigh. An article made for an elbow could similarly
have a compression sleeve attached that extended long enough for
use with the upper arm or forearm or both.
[0075] All ranges of numerical values for any dimension recited
herein are exemplary, are not to be considered limiting, and
include ranges therebetween, and can be inclusive or exclusive of
the endpoints. Optional included ranges can be from integer values
therebetween, at the order of magnitude recited or the next smaller
order of magnitude. For example, if the lower range value is 0.1,
optional included endpoints can be 0.2, 0.3, 0.4 . . . 1.1, 1.2,
and the like, as well as 1, 2, 3 and the like; if the higher range
is 8, optional included endpoints can be 7, 6, and the like, as
well as 7.9, 7.8, and the like.
[0076] While the foregoing is directed to embodiments of the
invention, other embodiments of the invention may be devised
without departing from the scope thereof, and the scope thereof is
determined by the following claims.
