Claims
What is claimed is:
1. A bandage comprising:
a liquid impervious front portion having an opening adjacent and
occupying a substantial part of the area of one end thereof;
a liquid impervious rear portion substantially coextensive with
said front portion and sealed thereto about the edges thereof;
and
an absorbent pad slightly larger than and sealed to the inside
edges of said opening and extending beyond the edges of said
opening at least in one direction toward the opposite end of said
bandage from said opening;
said rear portion remaining detached from said absorbent pad and
said front portion in the area between the edges of said rear
portion, thereby forming an open reservoir integrally with said
absorbent pad, said reservoir being adapted to receive and retain
excess body fluids produced by body wounds and incisions only
through said absorbent pad, said absorbent pad being relatively
small with respect to the volume of said reservoir.
2. A combination bandage and reservoir as set forth in claim 1
wherein said absorbent pad is a porous plastic heat sealed to the
edges of said opening.
3. A combination bandage and reservoir as set forth in claim 1
wherein said front and rear portions are sealed one to the other
along downwardly convergent lines from points adjoining the lower
edge of said opening and terminating in spaced relationship to form
a narrow gap therebetween.
4. A combination bandage and reservoir as set forth in claim 1
wherein said absorbent pad has an opening therein adapted to
receive a hollow tube extending to said reservoir area.
Description
This invention relates to bandages and more specifically to an
absorbent bandage having an integrally formed reservoir for the
storage of excess fluid.
In the treatment of wounds or incisions in the human body,
absorbent pads and bandages are generally utilized to keep the
wound clean and absorb fluids which may be discharge therefrom. In
instances where drainage is substantial, the bandage must be
replaced frequently. In some cases tubes are inserted in the wound
to facilitate drainage and the tube must be connected to a suitable
vessel beside the patient. Frequent replacement of bandages or
dressings requires additional time and effort on the part of
attendants and drainage tubes often result in immobilization of the
patient. This invention overcomes the foregoing difficulties
encountered in providing proper care for wounds and avoids much
discomfort to the patient and in many cases requiring the use of
drains the patient need not be immobilized. These advantages are
attained by the utilization of an absorbant material laminated with
a nonporous material which forms both a protective cover for the
absorbent pad and an integral reservoir into which fluids absorbed
by the pad may be discharged. With this improved bandage frequent
change of the dressing is not required and the possibility of
contamination is thereby reduced. If desired, an adhesive material
may be provided about the edge of the bandage to facilitate
application. In instances requiring a drainage tube, means are
provided for insertion of the tube directly into the reservoir
thereby avoiding the necessity of a separate receptacle and
immobilization of the patient.
The above and other objects and advantages of the invention will
become more apparent from the following description and
accompanying drawings forming part of this application.
In the drawings:
FIG. 1 is a perspective view of one embodiment of the absorbent
bandage and reservoir in accordance with the invention;
FIG. 2 is a cross-sectional side view of the bandage in FIG. 1,
taken along the line 2--2 thereof;
FIG. 3 is an enlarged fragmentary view of a portion of the bandage
shown in FIG. 2;
FIG. 4 is a cross-sectional view of the bandage of FIG. 1 taken
along the line 4--4 thereof;
FIG. 5 is an exploded perspective view of the bandage shown in FIG.
1;
FIG. 6 is a perspective view of an alternate embodiment of the
invention;
FIG. 7 is an enlarged cross-sectional side view of the bandage in
FIG. 6 taken along the line 7--7 thereof;
FIG. 8 is an enlarged cross-sectional view of the bandage shown in
FIG. 6 taken along the line 8--8 thereof;
FIG. 9 is a perspective view of still another embodiment of the
invention;
FIG. 10 is an enlarged cross-sectional view of FIG. 9 taken along
the line 10--10 thereof; and
FIG. 11 is an enlarged cross-sectional view of the bandage shown in
FIG. 9 taken along the line 11--11 thereof.
Referring now to the embodiment of the invention shown in FIGS. 1
through 5, the bandage is generally denoted by the numeral 20 and
includes a front portion 22 formed of a nonporous and preferably
plastic material having a window 24 in the upper part thereof.
Absorbent material 26 overlies the window 24 and may consist of
conventional cotton gauze, sponge, or any synthetic material which
is capable of being sterilized. The rear portion 28 is made of the
same material as the front portion and is essentially equal in
size. If desired, the rear portion 28 may extend beyond the front
portion 22 and carry an adhesive material to facilitate adherence
of the bandage to the body of the patient.
The bandage 20 includes a reservoir 30 into which the lower edge of
the absorbant material extends. More specifically the absorbent
material 26 is preferably slightly larger than the opening 24 and
may be bonded to the front portion 22 by the application of an
adhesive about the edges 32 of the window 24 or by the application
of heat to edges 34 sufficient to cause a fusing of the absorbent
material 26 and the front portion 22. If desired, the absorbent
material may be bonded to the rear portion 28 to hold it in
position. The rear portion or layer 28 is then adhered, heat sealed
or otherwise bonded to the front portion 22, so that the front and
rear portions together with the absorbent material form the
completed bandage with an integral reservoir 30 capable of
retaining fluids.
It is to be understood that the bandage need not be fabricated as
described above but may be made in any suitable manner provided
however that a fluid tight reservoir is formed and that the
absorbent pad extends into the reservoir. It is also noted that
with the foregoing structure an air space 31 may be provided
between the absorbent material 26 and the rear portion 28 to
facilitate the flow of the fluid into the reservoir 30.
An alternative embodiment of the invention is shown in FIGS. 6 and
7. In this embodiment of the invention the front and rear portions
22 and 28 are fused or otherwise sealed one to the other along
lines 38 and 40 to provide a narrow opening 41 into the reservoir.
This configuration functions as a trap to prevent the back flow of
fluid stored in the reservoir should the bandage be tilted to one
side or the other.
FIGS. 8 through 11 show still another embodiment of the invention
wherein a slit or hole 48 is provided in the absorbent material 26
and the front and rear portions 22 and 28 are sealed along lines 50
and 52 having downwardly extending portions 50a and 52a. With this
arrangement a tube or drain 54 may be inserted through slit 48 and
into the channel 55 created by the sealed portions 50a and 52a. The
drain 54 may be used to carry excess fluid directly from the wound
to the reservoir 30 while the absorbant pad 26 will absorb any
fluid which may emerge about the drain and discharge excess fluid
into the reservoir. As in the case of the preceding embodiment of
the invention, the fused lines 52 and 50 will also prevent back
flow of the fluid should the bandage be tilted.
While only certain embodiments of the invention have been
illustrated and described, it is apparent that alterations,
modifications and changes may be made as defined by the appended
claims.
