Claims
What I claim is:
1. In a perineal heating device,
a. an integrally formed body comprising a central portion and leg
rest portions extending outwardly from the central portion,
b. said central portion embodying a forwardly opening cylindrical
section, and
c. a source of heat in the cylindrical portion inset thereinto
inwardly of the forward face of the body, whereby heat from said
source may be directed against the perineum of a person using the
device.
2. A heating device according to claim 1 in which there is an
opening through the rear end of the cylindrical portion thereby to
provide a flow of air through the device and outwardly thereof in
response to heat generated by the heat source, whereby a
circulation of heated air is maintained against the perineum of a
person using the device.
3. A device according to claim 2 in which the opening is located
beneath the heat source so that air is thermally drawn through said
opening from the rear of the device and passes upwardly about and
thence outwardly of the heat source for impingement against the
body of a person using the device.
4. A device according to claim 1 in which said leg rest portions
are of less height than the top of the central portion and have
upper surfaces which are concave as viewed in front elevation.
5. A device defined in claim 1 in which the leg rest portions are
of less height than the top of the central portion and are concave
as viewed in front elevation and which as viewed in end elevation
slope upwardly from the front edges to a rounded apex and then
downwardly toward the rear of the device, thereby to support in
comfortable manner the legs of a person using the device and reduce
veinous obstruction of the legs.
6. A device in accordance with claim 1 in which there are openings
through at least one of the leg rest portions in communication with
the opening in the central portion, thereby permitting air to flow
through said leg rest into the central portion and thence outwardly
into contact with the perineum of a person using the device.
Description
This invention relates to a device useful for heat treatment of the
perineum of the human body and has for an object the provision of a
simple, inexpensive and effective device of the character
designated.
In the post operative or post natal care of patients it is
desirable to subject the perineum to heat, preferably in the form
of moving, heated air for the purpose of promoting circulation and
for drying. This treatment preferably is carried out with the
patient lying on his back and preferably with the knees slightly
elevated above the general level of the lower torso. Prior devices
known to me and used for such treatment usually consist essentially
of a holder and shield for the heat source such as an incandescent
lamp. Little attention has been paid to means for holding the heat
lamp properly directed relative to the parts of the body to be
heated nor to preventing veinous obstructions by lowering the leg
rests nor to making such devices of material cheap enough for
individual, disposable use by each patient. With prior devices
problems of sterilization to prevent cross transmission of
infection from one patient to another have been encountered.
Further, so far as I am aware, no means heretofore has been devised
to cause heated air, due simply to thermal action, to flow from a
heat source outwardly into contact with the patient's body.
In view of the foregoing I propose a perineal heating device
comprising an integral body of relatively cheap plastic material
such as Styrofoam, a central cylindrical portion of which carries
the heat source and from which central portion are carried
laterally projecting leg rests or supports, the leg rests being
contoured fore and aft and laterally for comfortable, elevated
support of the legs of a patient lying on his back. The heat source
may be an incandescent lamp and is located inwardly of the front
face of the body to hold the same safely out of contact with the
patient.
A device illustrating features of my invention is shown in the
accompanying drawing forming a part of this application in
which:
FIG. 1 is a front elevational view;
FIG. 2 is a plan view with certain parts broken away and in
section;
FIG. 3 is an end elevational view; and,
FIG. 4 is a detail sectional view taken generally along line 4--4
of FIG. 2 .
Referring now to the drawing for a better understanding of my
invention the same may consist of an integrally formed body of
relatively cheap, relatively light and fairly good heat insulating
material such for instance as Styrofoam or similar product. Thus,
the body portion may comprise the centrally disposed generally
cylindrical portion 10 and laterally, outwardly projecting leg
support portions 11 and 12. As shown, the leg supports are of less
height than the central portion 10.
As stated, the portion 10 is provided with a centrally located
opening generally cylindrical, and indicated at 13. This opening
terminates in a vertically disposed wall 14 and the opening 13 is
deep enough, fore and aft, to accommodate the usual incandescent
heating lamp 16 which may be mounted in a socket 17 embedded in the
solid rear portion 18, forming the back of the cylindrical portion
10.
Located beneath the lamp 16, and extending through the solid rear
wall portion 18 is an opening 19. Also, lateral openings 19a extend
through the leg support portions 11 and 12 and communicate with the
opening 19, as shown. As will presently appear, the openings 19 and
19a permit air to be drawn thermally from the rear and sides of the
device and propelled outwardly, into contact with the patient's
body as shown by the arrows 21 in the drawings.
The leg rest portions 11 and 12 as viewed in front elevation are
concave that is, they are shaped as shown in FIG. 1 generally to
the shape of the rear of a person's legs, in the thigh areas. As
viewed in side elevation, and at a point generally along section
line 4--4, the forward sloping surfaces 11a and 12a rise upwardly,
on a rather gentle slope to the apex 11b and 12b and thence
downwardly at more of a slope, to the rear of the body portion.
Thus, it will be seen that the leg portions 11 and 12 are so
contoured and shaped as to support in comfortable manner the legs
of the person and to largely eliminate veinous obstruction.
It will also be understood that current for the lamp may be
supplied to the same through the usual wires 22. Furthermore, the
opening 13 in the central portion 10 may be flared so that the
diameter of the same at the front of the device, that is, the side
facing the patient, is slightly larger than the rear of the opening
13. This affords a somewhat greater opportunity for the heated air
to take the course indicated by the arrows, and to impinge
outwardly onto the body of the patient.
In view of the foregoing it will be seen that I have devised an
improved, simple, economical and effective perineal heating device.
Since the device is constructed of extremely cheap material one may
be provided each individual patient, while being treated in the
hospital and the patient may take the device home as a part of the
post hospital treatment. It will be seen that with a patient lying
on his back and the device positioned so that the front thereof is
approximately 6 to 8 inches from his body, and current supplied to
the lamp, with the legs resting on the leg rests 11 and 12, heated,
drying air moves in accordance with the arrows from the openings 19
and 19a into the cylindrical opening 13 and thence outwardly into
contact with the patient's body as shown by the arrows 21. The flow
of air thus produced is due solely to the thermal action, and no
mechanical devices such as fans and the like are required.
My invention has proven to be extremely practical and satisfactory
and as stated eliminates two of the major difficulties with prior
devices, namely, the cross transmission of infection due to the
reuse of the same device by different patients and by and large,
due to the contour of the leg rests 11 and 12, eliminates veinous
obstruction in the leg areas.
While I have shown my invention in but one form, it will be obvious
to those skilled in the art that it is not so limited, but is
susceptible of various other changes and modifications without
departing from the spirit thereof.
