DETAILED DESCRIPTION
[0018] Examples will now be described more fully with reference to
the accompanying drawings. Examples are provided so that this
disclosure will be thorough, and will fully convey the scope to
those who are skilled in the art. Numerous specific details are
provided, such as examples of specific components, devices, and
methods, to provide a thorough understanding of examples of the
present disclosure. It will be apparent to those skilled in the art
that specific details need not be employed, that example examples
may be embodied in many different forms and that neither should be
construed to limit the scope of the disclosure. In some example
examples, well-known processes, well-known device structures, and
well-known technologies are not described in detail. The present
disclosure provides a chemotherapy protective gown that allows
effective and substantially complete user protection from
chemotherapy and hazardous drug treatments.
[0019] When an element or layer is referred to as being "on,"
"engaged to," "connected to," or "coupled to" another element or
layer, it may be directly on, engaged, connected or coupled to the
other element or layer, or intervening elements or layers may be
present. In contrast, when an element is referred to as being
"directly on," "directly engaged to," "directly connected to," or
"directly coupled to" another element or layer, there may be no
intervening elements or layers present. Other words used to
describe the relationship between elements should be interpreted in
a like fashion (e.g., "between" versus "directly between,"
"adjacent" versus "directly adjacent," etc.). As used herein, the
term "and/or" includes any and all combinations of one or more of
the associated listed items.
[0020] Although the terms first, second, third, etc. may be used
herein to describe various elements, components, regions, layers
and/or sections, these elements, components, regions, layers and/or
sections should not be limited by these terms. These terms may be
only used to distinguish one element, component, region, layer or
section from another region, layer or section. Terms such as
"first," "second," and other numerical terms when used herein do
not imply a sequence or order unless clearly indicated by the
context. Thus, a first element, component, region, layer or section
discussed below could be termed a second element, component,
region, layer or section without departing from the teachings of
the example examples.
[0021] Spatially relative terms, such as "inner," "outer,"
"beneath," "below," "lower," "above," "upper," "front," "rear,"
"horizontal," "vertical," and the like, may be used herein for ease
of description to describe one element or feature's relationship to
another element(s) or feature(s) as illustrated in the figures.
Spatially relative terms may be intended to encompass different
orientations of the device in use or operation in addition to the
orientation depicted in the figures. For example, if the device in
the figures is turned over, elements described as "below" or
"beneath" other elements or features would then be oriented "above"
the other elements or features. Thus, the example term "below" can
encompass both an orientation of above and below. The device may be
otherwise oriented (rotated 90 degrees or at other orientations)
and the spatially relative descriptors used herein interpreted
accordingly.
[0022] In one example, the presently disclosed gown is a
chemotherapy protective gown comprised of lightweight, flexible,
non-linting poly-coated fabric with long sleeves and knit cuffs
configured to be donned with the back open and secured around the
waist with attached poly-coated ties.
[0023] In one example, the presently disclosed gown comprises a
sealable or resealable ("(re)sealable"), releasably engageable
pocket 110 coupled (or detachably coupled) to an outward facing
surface of the gown.
[0024] With reference to FIGS. 1A and 1B, a front and rear view of
an exemplary disposable medical gown 100 is shown. Gown 100
comprises front surface 102 having coupled thereto extending arms
104 and collar 106. Designed to be donned with the back open and
secured around the waist with attached ties, the rear side of gown
100 comprises an open configuration consisting of continuous front
surface 102 terminating at rear edges 102a, 102b each rear edge
thereof having tie string 107 adjacent thereto.
[0025] Pocket 110 comprises a sealable or resealable closure
mechanism 117 along one or more vertical edges 112a, 114a or
horizontal edge 125. Pocket 110 is secured to the front of the gown
by a pocket-securing assembly comprising horizontal members 112,
114 of the pocket-securing assembly is a break in the perforated
poly-coated fabric to allow for a pass through opening from side to
side behind the pocket 110. In one example, pocket 110 is coupled
to a pocket-securing assembly that is coupled to gown 100, the
pocket-securing assembly providing for detachment of pocket 110
from the pocket-securing assembly. Pocket-securing assembly,
configured to releasably detach pocket 110 from gown 100, comprises
lower horizontal member 112 vertically separated from upper
horizontal member 114. Pocket-securing assembly members 112, 114
remain attached to gown 100 after removal of pocket 110. In one
example, pocket 110 is coupled to pocket-securing assembly of gown
100 in any suitable manner that provides release of pocket 110 from
pocket-securing assembly members 112, 114, including a perforated
horizontal region, a weak seam, a heat seal, an adhesive, Velcro or
stitches. Pocket-securing assembly is secured directly to gown 100
using a seam, a heat seal, an adhesive, Velcro or stitches.
[0026] In the example gown 100 shown in FIG. 1A, pocket-securing
assembly securing pocket 110 is positioned below the neckline and
centered side to side and releasably secures pocket 110 to gown
100. Other positions, orientations, and number of pocket assemblies
can be employed.
[0027] With reference to FIG. 2, an alternative exemplary
disposable medical gown 200 is shown. Gown 200 is similar to gown
100 but includes a pair of sealable, releasably engaged pockets
210a, 210b releasably securable to outward facing surface of gown
200 by way of separate pocket assemblies located in proximity to
corresponding edges 103 of front surface 102 and edge 103. Pockets
210a, 210b are shown angled relative to edge 103 (or longitudinal
axis of gown) for facilitating introduction of a user's hand
together with contaminated medical device. Other orientations and
placements of pockets 210a, 210b about the outward facing surface
of gown 200 are envisioned.
[0028] With respect to FIG. 3, a front view of the exemplary
disposable medical gown 100 is shown after removal of the sealable,
removable pocket 110 from the pocket-securing assembly.
Pocket-securing assembly members 112, 114 can be configured to
couple with pocket 110 using perforations, adhesives, stitching,
welding, Velcro, etc. Force required to remove pocket 110 from
pocket-securing assembly members 112, 114 are configured to be less
than detachment of components 112, 114 from gown 100 so that gown
100 is not compromised.
[0029] With respect to FIG. 4, a detailed view of disposable
medical gown pocket 110 with sealable closure mechanism 117 is
shown. In one example, pocket 110 comprises a sealable closure
mechanism 117 such as ziploc-like construction, as shown. In one
example the sealable closure mechanism 117 of pocket 110 is
configured to be essentially vapor and liquid impervious. In one
example, the sealable closure mechanism 117 of pocket 110 is
configured in initially open state for receiving contaminated
medical devices and the like, and transitions to a locked sealed
state when closure mechanism 117 is activated to prevent or
eliminate accidental opening of closure mechanism 117 during
removal and/or disposal of the pocket 110. Pocket 110 can be
configured with
[0030] In yet another aspect, the (re)sealable closure mechanism of
pocket 110 comprises a flap with an adhesive tab or corresponding
Velcro components. In one example the adhesive tab used as a
sealable closure of pocket 110 is configured to be essentially
vapor and liquid impervious.
[0031] FIG. 5 is a sectional view along section line 5-5 of FIG. 1
of the exemplary disposable medical gown 100 with sealable,
removable pocket 110. Pocket 110 comprises outer-facing surface 150
and gown-facing surface 152 adjacent to gown 100. Pocket 110 is
secured at horizontal edges 112a, 112b to pocket-securing assembly
members 112, 114, respectively. The absence of securement at
vertical edges form a pass through pocket.
[0032] Closure mechanism 117 is shown positioned adjacent to edge
112a, but can be along horizontal edge 125.
[0033] FIG. 6 is a sectional view along section line 6-6 of FIG. 3
of the exemplary disposable medical gown 100 with the sealable,
removable pocket 110 removed. Pocket-securing assembly members 112,
114 remain secured to gown 100.
[0034] While various configurations of gown 100, 200 are possible,
in one example, the gown can be provided in a variety of sizes such
as Gown Size: Small--Gown body 37 inches long by 50 inches wide,
Sleeves 28 inches long from shoulder to cuff, Elastic cuffs 3
inches long; Gown Size: Large--Gown body 39 inches long by 52
inches wide, Sleeves 29 inches long from shoulder to cuff, Elastic
cuffs 3 inches long; Gown Size: Extra Large--Gown body 41 inches
long by 54 inches wide, Sleeves 30 inches long from shoulder to
cuff, Elastic cuffs 3 inches long; Gown Size: Double Extra
Large--Gown body 43 inches long by 56 inches wide, Sleeves 31
inches long from shoulder to cuff, Elastic cuffs 3 inches long,
etc.
[0035] In one example, the dimensions of the sealable, releasable
pocket 110, 210a, etc., are configured dimensionally about 9 inches
wide by about 11 inches tall and are of the thickness of between
2-10 mil. In one example, sealable closure mechanism 117 comprises
a lanyard 119 with loop to allow for opening with a single finger
pull. In another example, pocket 110, 210a, etc. contains gussets
118 long along both vertical sides so that once the pocket is
detached and removed from gown 100, 200 via breakage from the
pocket-securing assembly, gussets 118 can be expanded to allow for
the pocket to be free standing, if desired.
[0036] In one example, the disposable medical gown 100, 200
disclosed herein may be made from any suitable thermoplastic
polymer, including polypropylene, polypropylene with a polyethylene
coating, etc. In other examples, the disposable medical gowns may
utilize spunbond-meltblown-spunbond (SMS) materials.
[0037] In one example, the body of gown 100, 200 is comprised of
lightweight, flexible, non-linting poly-coated fabric (woven or
nonwoven fabric of thermoplastic polyolefin, polyurethane,
polyethylene to, polycarbonate, or nylon, for example) with long
sleeves and knit cuffs. In one example, a poly-coated fabric that
is impervious to cisplatin, cyclophosphamide, dacarbazine,
doxorubicin, etoposide, fluorouracil, methotrexate, mitomycin,
paclitaxel, vincristine with no breakthrough for up to 240 minutes
(without displaying swelling and degradation) is employed.
[0038] In one example, the medical gown 100 provides a barrier to
blood and viral agents, and meets the requirements of ASTM F1670
and ASTM F1671. In another example, the gown is breathable to
provide comfort to the wearer, e.g., has a breathability, expressed
in terms of MVTR as measured by ASTM E96 of at least 250 g/m2/24 hr
at standard conditions of about 75.degree. F. and a relative
humidity of about 65%.
[0039] In one example, pocket 110, 210a, etc., is made of a liquid
impervious fabric or material. In another example, pocket 110,
210a, etc is made of a vapor and liquid impervious fabric or
material. In one example, pocket 110, 210a, etc. is comprised of
barrier plastic with a (re)sealable opening at the top and heat
sealed edges to provide liquid leak resistant barrier. For example,
a thermoplastic olefin barrier that is impervious to many
chemotherapy agents and drugs such as cisplatin, cyclophosphamide,
dacarbazine, doxorubicin, etoposide, fluorouracil, methotrexate,
mitomycin, paclitaxel, vincristine, with no breakthrough of these
chemotherapy agents for up to 240 minutes is employed.
[0040] In one example, the releasable pocket 110, 210a, etc is
formed of a material configured to resist cutting, tearing,
puncturing and abrasion while maintaining flexibility for receiving
the contaminated medical device. Such durability can be provided
and/or controlled by adjusting the thickness of the material used
to make the pocket. One or more portions of pocket 110, 210a, etc
can be reinforced or augmented, e.g., increased thickness about the
edges, or can be strengthened or toughened using other known
methods of reinforcement, so as to minimize or eliminate puncture
or tear by contaminated medical devices, such as those having sharp
points or edges, etc.
[0041] In one example, the pocket 110, 210a, etc is prepared from a
continuous single layer or multiple layer chemical barrier material
having chemical barrier properties, for example, material normally
used for protection against military warfare agents as well as
other toxic industrial chemicals and materials, such as for example
polyvinylidene chloride (PVDC), ethylene vinyl alcohol copolymer
(EVOH), nylons, acrylonitrile methacrylate copolymer (AN-MA),
polyvinyl alcohol (PVOH), and others. In one example, the pocket is
constructed of material that provides softness and flexibility, for
example, multi-layer coextruded films such as, but not limited to
polyvinylidene chloride (PVDC) with exterior layers of melt
processable polymers (i.e., linear low density polyethylene
(LLDPE), ethylene vinyl acetate (EVA), and chlorinated polyethylene
(CPE)), commercially available examples of which include the
Saranex.RTM. series of barrier films available from Dow Chemical
Company, Midland Mich., such as Saranex.RTM. 14P, Saranex.RTM. 23P,
Saranex.RTM. 35P, Saranex.RTM. 520, Saranex.RTM. 750, Saranex.RTM.
452, Saranex.RTM. 650G, and Saranex.RTM. 652G.
[0042] The disposable medical gown 100 and/or pocket-securing
assembly and pocket 110, 210a, etc disclosed herein may be formed
monolithically with a front surface 102, at least one side portion
103, at least one arm portion 104. Some or all portions (including
the releasably engageable pocket) of the disposable medical gown
100, 200 may be formed individually and coupled together to form
the disposable medical gown 100, 200. In one example, the front
surface 102, at least one side surface 103, and at least one arm
portion 104 are coupled together in any suitable manner, including
by a perforated material, a weak seam, a heat seal, an adhesive, or
stitches, etc.
[0043] For example, to wear an example gown (e.g., gown 100, 200)
of the present disclosure, the user inserts his/her head within the
opening of collar 106 and his/her arms into the arm portions 104.
The user then may couple the straps 107 so that the gown fits
comfortably around the user (e.g., the front portion of the gown,
etc.). Alternatively, and depending on the user, the tie strings
107 can be secured together at the rear portion of the gown, etc.
(again, depending on the size of the user and so that the gown
comfortably fits around the user).
[0044] The foregoing description of the examples has been provided
for purposes of illustration and description. It is not intended to
be exhaustive or to limit the disclosure. Individual elements or
features of a particular example are generally not limited to that
particular example, but, where applicable, are interchangeable and
can be used in a selected example, even if not specifically shown
or described. The same may also be varied in many ways. Such
variations are not to be regarded as a departure from the
disclosure, and all such modifications are intended to be included
within the scope of the disclosure.
