Claims
I claim:

intravenous feeding or the like, the forearm support board
including a flat substantially rigid core member of suitable width
and length to fit comfortably the underside of the forearm and hand
of a patient, the core member being immediately encased on all
sides by an envelope sealed around the core member, the envelope
comprising confronting panels of material sealed together at their
periphery and at least one of said confronting panels comprises a
cushioning material.
2. The forearm support board of claim 1 wherein both of said
confronting panels of material of the envelope are made of said
cushioning material.
3. The forearm support board of claim 1 wherein said confronting
panels of material are of thermoplastic material and are melted
into sealed relation at their periphery.
4. The forearm support board of claim 1 wherein said cushioning
material is a porous foam material permitting air to circulate
beneath a forearm supported thereon.
5. The forearm support board of claim 2 wherein each of said
confronting panels is a porous foam material permitting air to
circulate beneath a forearm supported thereon.
Description
This invention relates generally to a means for supporting the arm
and hand of a patient for intravenous feeding or the like, and more
particularly to a disposable arm board unit for use in hospitals or
clinics.
Heretofore, many different forearm support boards have been used
for the purpose of supporting a patient's hand and forearm during
intravenous feeding or the like, but these arm boards left much to
be desired from the standpoint of cost and convenience of use. In
many cases, the forearm support boards are fabricated at the
hospital or clinic when needed by nurses or other employees by
using various available materials such as cardboard, wood, cotton,
gauze, tape and the like to fashion a suitable device for a
particular patient. There is presently on the market various
different types of forearm support boards which hospitals and
clinics may purchase but these units leave much to be desired.
It is an object of this invention to provide a forearm support
board which includes all or most of the features of the more
expensive board boards such as padding and a continuous outer
casing and yet can be manufactured at such a low cost that it can
be disposed of after one or two uses.
Briefly, the forearm support board of this invention provides a
readily deformable and padded arm and hand receiving surface formed
by a foam material made of such materials as polyethylene,
polystyrene, polyurethane or polyvinylchloride foam, secured
directly over a rigid board by heat sealing the periphery thereof
to a sheet of material on the bottom of the board. The foam
material automatically partially conforms to the configuration of
the forearm and hand of a patient, and is of such inexpensive
construction that it can be a single or double use disposable unit.
By using the foam material to form both the padded support for the
forearm support board and part of a readily sealable envelope for
the rigid member, the cost of the board is materially reduced over
boards of prior construction of similar quality. Also, the porous
foam material allows air to circulate between the patient's arm and
the support board thus reducing or eliminating sweating of the arm
of the patient when in contact with such support board.
Other objects, advantages and features of this invention will be
more fully realized and understood from the following detailed
description when taken in conjunction with the accompanying
drawings wherein like reference numerals throughout the various
views of the drawings are intended to designate similar elements or
components.
FIG. 1 is a perspective view showing the forearm support board unit
of this invention fastened to a patient's arm;
FIG. 2 is a perspective view of the forearm support board unit of
this invention not fastened to a patient;
FIG. 3 is a sectional view taken along line 3-3 of FIG. 2;
FIG. 4 is a sectional view similar to that of FIG. 3 but showing
another form of this invention;
FIG. 5 is an enlarged fragmentary sectional view showing the
construction of the outer edge portions of the confronting sheet
members of FIG. 3; and
FIG. 6 is an enlarged fragmentary sectional view showing the
construction of the outer edge portions of the confronting sheet
members of FIG. 4.
Referring now to FIG. 1, the forearm support board of this
invention is designated generally by reference numeral 10 and is
shown fastened to the forearm and hand of a patient designated by
reference numeral 12. The forearm support board 10 is secured in
position, for example, by bands of tape 14 and 16 which is the
customary way of fastening forearm support boards of this type. The
forearm support board 10 has particular utility when used for
intravenous injections at the back of the hand for supplying fluid
medication to the patient through a flexible tube 18. However, it
will be understood that the forearm support board of this invention
may be used for various other purposes, as for example, splints or
the like.
As seen in FIGS. 2 and 3, the forearm support board 10 has a soft
foam rubberlike covering layer 20 of material of suitable thickness
forming the upper arm engaging surface thereof and a lower
sheetlike layer 22 which, together with the covering layer 20,
completely encase a rigid core member 24. The covering layer 20 is
most advantageously made of a heat sealable cushioning material
like polyethylene, polystyrene, polyvinylchloride or polyurethane
foam. In the embodiment shown in FIGS. 2 and 3, the lower layer 22
is most desirably formed of a thin heat-sealed sheet of synthetic
material. The covering layer 20 immediately overlies the rigid core
member 24 and the peripheral edge portions of the covering and
lower layers 20 and 22 extend a slight distance beyond the edges of
the rigid core member 24 where they are heat sealed together. The
heat sealing is most advantageously carried out by high frequency
or induction heating. When polyurethane is used as a covering
layer, to provide a readily tearable seal the polyurethane foam is
an open cell foam impregnated with polyvinylchloride and the lower
layer is a polyvinylchloride sheet or film. As best seen in FIG. 5,
the confronting edge portion 20a of the covering layer 20 forms a
downwardly and outwardly turned portion 20b which partially
embraces the rigid core member 24 about the periphery thereof, and
the confronting edge portion 22a of the lower layer 22 forms an
upwardly and outwardly turned portion 22b in abutting confronting
relation with the portion 20b of the covering layer 20 and is heat
sealed thereto at 26. Therefore, the lower layer 22 also partially
embraces the rigid core member 24 and together with the covering
layer 22 form an envelope which preferably tightly encases the
rigid core member 24.
An alternate form 10a of this invention is shown in FIGS. 4 and 6
wherein the lower layer 22 of FIGS. 3 and 5 is replaced by a soft,
heat sealable, foam rubberlike layer 28 similar to that of the
covering layer 20. Here the lower layer 28 includes a confronting
edge portion 28a which forms an upwardly turned portion 28b (FIG.
6) in abutting relation with the downwardly turned portion 20b of
the covering layer 20. These cushioning layers 20 and 28 are heat
sealed together about their periphery outwardly of the rigid core
member 24, the heat seal being indicated by reference numeral
30.
Accordingly, a forearm support board constructed in accordance with
this invention is relatively simple and inexpensive to manufacture
and, therefore, is disposable without incurring undue cost to the
user.
In view of the foregoing detailed description together with the
accompanying drawings, it will be understood that variations and
modifications may be effected without departing from the spirit and
scope of the novel concepts of this invention.
