said intermediate portion, when said corset is laid out in a plane,
having a concave lower edge for conforming to the contour of the
buttocks region of the patient's torso when the corset is applied
about the lower torso, and an elongated stay in each of the
opposite end portions of said corset and extending in a
substantially vertical direction to prevent rolling of said edges.
Description
The present invention relates to a therapeutic support and
particularly to a novel improved lumbo-sacral support.
Various types of therapeutic supports or corsets have been provided
in the past for the lower torso of a human being and particularly
for the lumbar region. While in most cases such corsets have
provided the requisite support, they also are replete with many
disadvantages. The principal disadvantage of existing supports is
lack of comfort when worn and this is primarily a result of the
unflexibility built into the corset through the use of strong rigid
metal stays and lack of appropriate padding and ventilation. Other
causes of patient discomfort when wearing existing supports are the
general overall bulkiness of the supports and their tendency to
ride or bunch up along the patient's lower torso. Moreover, many
corsets do not enable the patient to sit, bend or variously flex
his lower torso without appreciable difficulties. Further, the use
of relatively rigid non-flexible stays causes unequalized and
undesired pressure against the various regions of the lower torso
and occasionally the rigid stays press against the torso producing
a pinching effect. Another objection to present day therapeutic
supports of this type is the lack of a contoured fit in the absence
of a custom fit. Furthermore, certain supports are comprised of
nonwashable and air impermeable materials, the latter material
precluding circulation of air along the torso.
The present invention provides a novel and improved therapeutic
support particularly for the lumbo-sacral region which eliminates
and/or minimizes many of the problems associated with prior
supports of this type and provides a support having various
advantages in construction, comfort and use in comparison with such
prior supports. Particularly, the present lumbo-sacral support
comprises a corset formed of a washable nylon elastic material for
encompassing the lower torso of the patient, the corset having an
enlarged intermediate portion conformable to the lumbar region. The
reduced width end portions of the corset are adapted to extend
about the pelvic area and overlie the abdominal region, the end
portions carrying fasteners of the "Velcro" type whereby the corset
may be readily and adjustably secured about the lower torso and
also readily released therefrom. To enhance the comfort of the
wearer, the intermediate enlarged portion of the corset carries a
plurality of elongated vertically extending laterally spaced stays
on the outer side of the corset and in overlying relation to
padding disposed along the inside face of the intermediate corset
portion. The stays are prebent to approximate the contour of the
lumbar region including the buttocks area and yet are sufficiently
flexible to permit the patient to comfortably sit, bend, etc.,
without appreciable difficulties. The padding on the inside face of
the intermediate portion of the corset precludes direct contact
between the patient and the prebent stays and, with the padding
provided in vertical elongated ribs in lateral registry with the
stays, direct bearing of the stays against the patient's skin is
precluded. Additionally, the corset is provided with a pair of
vertically extending stays in the end portions thereof whereby the
upper and lower edges of the corset are precluded from rolling up
or down along the lower torso.
The use of elastic nylon material permits air to circulate in the
area between the corset and the lower torso precluding and/or
alleviating chafing and other discomforts. The elastic material in
conjunction with the lightweight metal stays also permits the
support to be light in weight and simple and low cost in
construction. To further enhance the comfort of the patient and to
ensure that the corset does not curl about the patient's torso, a
pair of straps are secured to the corset adjacent the upper and
lower edges of its intermediate portion. The straps are each
provided with a buckle for fastening the straps about the torso.
When the corset is worn, the straps respectively extend about and
along the upper and lower edges of the corset firmly securing it to
the patient. Moreover, the lower strap extends about the buttocks
area ensuring a more anatomical fit.
Accordingly, it is a primary object of the present invention to
provide a novel and improved therapeutic support and particularly a
therapeutic support for the lumbo-sacral region.
It is another object of the present invention to provide a novel
lumbo-sacral support which is easily applied about the lower torso
and comfortable to wear.
It is still another object of the present invention to provide a
novel and improved lumbo-sacral support having a contoured fit and
which is readily provided in various sizes.
It is a further object of the present invention to provide a novel
and improved lumbo-sacral corset formed of an elastic permeable
material for enhancing the support afforded thereby and to provide
for air flow circulation through the corset.
It is a further object of the present invention to provide a novel
and improved lumbo-sacral support having prebent stays precluding
roll up of the support and thereby enhancing the comfort of the
patient.
It is a related object of the present invention to provide a novel
and improved lumbo-sacral support which is light in weight, and
simple and low cost in construction.
These and further objects and advantages of the present invention
will become more apparent upon reference to the following
specification, appended claims and drawings, wherein:
FIG. 1 is a perspective view of a therapeutic support constructed
in accordance with the present invention and illustrated as applied
about the lower part of the human torso;
FIG. 2 is a view of the support as unfolded in a plane looking at
the inside face of the support;
FIG. 3 is a view similar to FIG. 2 looking at the outside face of
the support; and
FIGS. 4, 5 and 6 are cross sectional views thereof taken generally
about on lines 4--4, 5--5 and 6--6 in FIG. 3.
Referring now to the drawings, particularly to FIGS. 1-3, there is
disclosed a support or corset, generally indicated 10, particularly
for therapeutic use in the lumbo-sacral region of the human anatomy
for alleviating the effects of, for example, low back strains,
lumbar nerve root irritations, etc. Support 10 comprises an
elongated piece of elastic material 12, preferably nylon elastic,
having an intermediate portion 14 of enlarged height and opposite
end portions 16 and 18. The upper edge 18 of corset 10, when the
latter is unfolded in a plane as illustrated in FIGS. 2 and 3,
extends along a substantially straight line while the lower edge 20
is arcuately contoured upwardly from the intermediate portion 14
toward the opposite end portions 16 and 18. The arcuate edge 20 is
contoured to approximate the contour of the lower portion of the
buttocks area and the sides thereof which it encompasses. A waist
band 22, formed of similar elastic material, is integrally provided
about the upper margin of corset 10 while the end and lower edges
are bound and stitched as at 24.
There is particularly illustrated in FIGS. 2 and 4 a foam pad 26
comprised of an inner core of cellular foam material 28 in a
generally rectangular shape with its lateral edges converging
slightly in a downward direction. Pad 26 also includes a covering
of soft in-elastic material 30 having a generally similar shape as
the foam material and stitched to the intermediate corset portion
14 about the periphery of the former as at 32 thereby fully
enclosing the foam core 28 between material 39 and the elastic
material comprising the intermediate corset portion 40.
Referring now to FIGS. 3 and 4, a plurality of prebent metal stays
38 are laterally spaced one from the other along the outside
surface of the elastic intermediate corset portion 14.
Particularly, strips of elongated non-elastic material 40
substantially coextensive in length with stays 38 are stitched
along their side and lower edges as at 44 to form with the
intermediate portion 14 pockets 42, the upper ends of which are
open for receiving stays 38. As illustrated in FIG. 3, these
pockets 42 are laterally spaced one from the other and extend
substantially the entire height of the intermediate portion 40 of
the corset.
It will be appreciated that the metal stays 38 are prebent to
approximate the contour of the lumbar region of the lower torso.
That is to say, and referring now particularly to FIG. 4, the metal
stays 38 are bent to form a generally shallow S configuration for
conformity to the small of the back and the buttocks region. The
prebent stays 38 are also disposed along the outside face of the
intermediate corset portion 14 whereby the foam padding 28 is
disposed between the stays and the lower part of the patient's
torso when the corset is applied thereto. To ensure the patient's
comfort in the area of stays 38, the pad or foam material 26 is
vertically stitched at longitudinally spaced positions along the
height of the intermediate portion 14 as indicated at 46.
Particularly, the stitching 46 is provided to form a plurality of
ribs 48 of padded material, with ribs 50a-50d thereof lying in
registry with the metal stays 38 on the opposite side of the
intermediate portion 14. That is to say, when the corset is applied
to the patient, the ribs 50a-50d lie on the inside face of corset
10 directly between the stays 38 and the lower part of the
patient's torso, the stitching 46 ensuring that the ribs 50a-50d of
foam material are retained in that protective position.
Referring now to FIGS. 2, 3 and 6, a metal stay 52 is provided each
of the opposite end portions 16 and 18 of corset 10. Particularly,
an elongated strip of non-elastic material 54 is stitched along its
sides and lower end to the outside face of each end portion 16 and
18 to form with the end portion a pocket for receiving the
vertically extending stay 52. The stay extends from a position
spaced from the lower edge 20 of the corset end portion to a
position contiguous with upper edge 18. As noted hereinafter, when
the corset is applied about the patient, stays 52 prevent the
corset from rolling up or down, particularly when the patient bends
or sits.
Directly adjacent the end portion 16, there is provided a fastening
strip 56 substantially coextensive in height with the height of
corset end portion 16. Strip 56 comprises a Velcro type fastener
and carries the plurality of hooks characteristic of such
fasteners. The opposite end portion 18 is also provided with a pair
of strips 58a and 58b of the looped felt-like material
characteristic of the other portion of a Velcro type fastener. Two
strips 58a and 58b are provided in order to afford a degree of
adjustability about the lower torso when applied thereto. It will
be appreciated that the Velcro type fastener forms a continuous
type of fastener throughout the height of the end portions 16 and
18 and this precludes distortion of the elastic material forming
the body of the corset, i.e., precludes portions of the elastic
corset from being tighter than other portions, and provides for
uniform stretching thereof throughout substantially the entirety of
the height of the corset.
Referring to FIGS. 2 and 3, medial portions of upper and lower
straps 60 and 62, respectively, are stitched to the intermediate
portion 14 of corset 10 as at 66 and 68, respectively, centrally of
padding 26 and extend along the outside face of the corset.
Fasteners 60 and 62 are provided with buckles 70 and 72,
respectively, whereby their opposite ends can be inserted through
the buckles and the corset firmly secured about the lower part of
the torso.
It will be appreciated that the corset hereinbefore described may
be readily applied about the lower torso of the patient.
Particularly, the intermediate portion 14 may be disposed about the
patient's lumbar region with end portions 16 and 18 being wrapped
about the side and abdominal regions and joined one to the other by
pressing Velcro strip 56 against one or both of strips 58a and 58b.
The larger lateral extent of strips 58a and 58b provides a degree
of adjustability when initally securing the corset about the torso.
When secured in proper position, lower strap 62 is wrapped about
the extreme lower torso along a path contiguous and parallel to the
lower edge 20 of the corset and buckled. In this manner, lower
strap 62 contours the buttocks area and ensures an anatomical fit.
Likewise, the upper strap 60 is wrapped about the patient's waist
and buckled in the front, the strap 60 extending along the
waistband 22 of corset 10. It will be appreciated that with the
lumbo-sacral support thus applied, pad 26 bears against the
lumbar-sacral region with the prebent and contoured stays 38
providing appropriate pressure. The stays 38, as hereinbefore
noted, are semi-rigid and will limitedly flex when the patient sits
or bends. Also, the stays 52 in combination with the location of
the straps 60 and 62 as they bear about the upper and lower edges
of corset 10 respectively preclude rolling of the upper and lower
edges 18 and 20.
It will be appreciated that the lumbo-sacral support hereof is
provided in various sizes, depending upon the size of the patient
undergoing treatment. It will also be appreciated that the prebent
and contoured stays 38 in conjunction with the contoured lower edge
of the corset provide substantially a custom comfortable fit about
the patient. Moreover, the foregoing described support is
fabricated utilizing materials which are substantially readily
available and low in cost and which materials can be brought
together to form the present corset in a ready and easy manner
chiefly by a stitching or sewing operation.
The invention may be embodied in other specific forms without
departing from the spirit or essential characteristics thereof. The
present embodiment is therefore to be considered in all respects as
illustrative and not restrictive, the scope of the invention being
indicated by the appended claims rather than by the foregoing
description, and all changes which come within the meaning and
range of equivalency of the claims are therefore intended to be
embraced therein.
