Description
This invention relates to new and useful improvements in surgical
dressings. More particularly, the invention relates to a dressing
adapted for application to the body over a fistula or an open
penetrating type of wound.
The problem of providing adequate dressings for large open draining
wounds has long been prevalent. Penetration type wounds are
frequently found in the combat zones and require immediate dressing
in order to prevent infection. In surgery abnormal passages leading
from an abscess or hollow organ, commonly known as a fistula,
require drainage in order to carry off the bodily fluids emitted in
proximity to the body opening. Prior to the present invention, it
was necessary to continually change the dressings for such wounds
or fistula or else to provide very cumbersome devices or apparatus
to evacuate the drained fluids from the area adjacent the wound.
Failure to properly drain such wounds may result in abscesses,
infection and slow healing.
An object of the present invention is to provide a wound dressing
which forms an airtight, leak-proof seal around the wound or body
opening.
A further object of this invention is to provide a leak-proof
sealed dressing having provision for connection of an external
drainage means.
A still further object of the invention is to provide a
nonallergenic dressing that prevents foreign substances from
contacting the wound and seals the wound against the atmosphere and
prevents fluids from penetrating into the area of the dressing.
A still further object of the present invention is to provide a
fistula or penetrating wound dressing which is compact, light in
weight, and which can be easily, quickly and securely applied to
such wounds.
Another object of this invention is to provide a dressing for
penetrating wounds or fistula formed of a flat piece of plastic
material or the like having openings therein into which collodion
may be applied to act as a sealing medium.
Another object of this invention is to provide a wound dressing
having a removable dome drain portion.
Still another object of this invention is to provide a dressing
having a transparent dome portion therein which allows visual
inspection of the wound and of the healing process without the
necessity of the removal of the dressing and its associated
trauma.
A yet further object of this invention is to provide a wound
dressing having drainage facility which can be applied with minimal
skill which is simple in construction, inexpensive to manufacture,
and safe and efficient in use.
The above and other objects and features of the invention will
become more apparent from a consideration of the following
disclosure.
In order that the general principles of this invention may be
readily understood, reference should be had to the following
detailed description taken in conjunction with the accompanying
drawings which illustrate the best mode now contemplated by me for
carrying out my invention:
FIG. 1 is a plan view of one form of the dressing allied to a
portion of the human anatomy and showing connection to an
evacuation pump;
FIG. 2 is a plan view of the dressing shown in FIG. 1;
FIG. 3 is an end view of the dressing taken from the lower end in
FIG. 2;
FIG. 4 is a cross-sectional view of the dressing taken along the
line 4-4 of FIG. 2;
FIG. 5 is a cross-sectional view showing a modification of the dome
portion of the dressing; and
FIG. 6 is a plan view of a further modification of the
invention.
Reference is now made specifically to the drawings wherein like
reference numerals designate similar parts throughout the several
views and wherein the fistula and penetrating wound dressing
constituting the subject matter of this invention is designated
generally at 10.
The main body of the dressing is preferably formed from a single
sheet of synthetic transparent plastic of relatively thin section
which may be molded under heat and pressure by conventional means.
The dressing is molded of the plastic material so as to provide a
flat peripheral base 11 with a central upstanding elongated dome
structure 12. The dome is spaced from three sides of the base, but
has its one end in communication with the adjacent edge by means of
a tapered throat portion 13. The throat terminates in a cylindrical
nipple 14 which preferably extends outwardly of the base 11. A
plurality of small openings are punched or otherwise provided
around the edge of the base. Two rows of such openings are shown in
FIGS. 2 and 5, although any number may be provided.
The dressing is applied to the wound as shown in FIG. 1 with the
dome portion 12 directly over the fistula F or other type of
gapping wound which has first been properly cleansed. A viscous
solution such as collodion may then be sprayed, brushed, or poured
about the periphery of the base 11 so that the same penetrates
through the holes 15. Collodion is a known coating agent for wounds
and also is useful in securing dressings and comprises a viscous
solution of pyroxylin. Obviously other equivalent compounds could
be used as well.
After the dressing is secured to the body, the nipple 14 may be
connected to a conventional form of vacuum evacuation pump P as by
means of a flexible rubber or synthetic conduit 16 which will
frictionally fit over the nipple 14 in a tight sealed manner. It
will be understood that fluid draining from the wound will be
evacuated continually in this manner. If it is not desired to
continually evacuate the wound, a tapered plug or the like not
shown may be secured within the nipple 14 until such time as
drainage of the wound is desired. With the dressing affixed as
shown in FIG. 1, medical personnel have continual visual access to
the wound through the raised transparent dome portion 12 which also
serves as a collection chamber for the drained fluid.
It will be understood that the size of the base portion 11 and/or
the size of the dome 12 may vary and different configurations may
be used depending upon the particular type of fistula or wound to
which the dressing is to be applied. It is contemplated that a
circular form of base and dome may be feasible as well as
rectangular arrangements of various dimension.
The modification shown in FIG. 5 presents a dome 20 having a
peripheral flange 21 which may be removably secured to base portion
11 as by means of conventional adhesives. In all other respects the
dome 20 is identical to the dome 12 and may include the tapered
throat portion 13 and the nipple portion 14. With this modified
form of the dressing, the dome portions may be removed for
physically cleaning the wound or in order to provide a clean, new
dome portion. Alternatively, the dome 20 may have a continuous
peripheral flange without the throat 13 and the nipple and drainage
may be provided by merely removing the dome along with the fluid
accumulated therein. Here again collodion may be used to secure the
dressing to the body of the user since the collodion is more
adhesive and less irritating than conventional adhesive tapes and
can remain in place for a longer period of time and yet allow wound
hygiene without the necessity of changing the entire dressing. The
collodion will also form an airtight and leak-proof seal between
the dressing and the body which will prevent air and fluids from
getting to the wound.
In the further modification shown in FIG. 6, the dressing is
designated generally at 30 and includes a base portion in the form
of rectangular sheet of tape 31 having a central rectangular
opening and its bottom surface coated with a contact adhesive. The
opening is covered by means of a cotton mesh or gauze 32. and the
mesh has sealed centrally thereon a leak-proof plastic dome 33
similar to the dome 12 in the preferred embodiment. Dome 33 is
provided with a peripheral flange 34 which may be adhesively
secured to the cotton mesh material 32. It will be understood that
the mesh directly beneath the dome will be removed. The dome 33 is
provided with a tapered throat portion 35 terminating in a
cylindrical nipple 36 through which a vacuum pump hose 37 may be
connected.
In this embodiment of the invention the dressing may be applied to
the body by means of the adhesive tape 31 and collodion may further
be applied over the foraminous mesh material 32 thereby penetrating
to the skin and providing a leak-proof tight and secure seal of the
dressing to the body. This modification of the invention also may
be made in a circular form with an annular adhesive base portion
similar to the rectangular portion 31 and with an annular cotton
mesh portion and a hemispherical plastic dome.
While I have shown and described a preferred embodiment and several
modifications of the invention, it is to be understood that the
drawings and detailed disclosure are to be construed in an
illustrative rather than a limiting sense since various
modifications and substitutions of equivalents may be made by those
skilled in the art within the spirit and scope of the invention as
defined in the appended claims.
