THERAPEUTIC BED PAN BACKGROUND OF THE INVENTION This invention relates to a combination bed pan and foam pad unit to be used on beds being utilized by invalid patients and the like. In the past in nursing homes, hospitals, or in private homes where invalid patients with certain diseases and afilictions are bedridden, a problem arises from bed sores which these patients de velop. These bed sores or decubitus ulcers result from a loss of blood circulation caused by pressure on the skin particularly pressure over a bony protuberance. The pressure on areas of support exceeds the mean capillary blood pressure and these areas are vulnerable to the decubitus ulcers. Other factors which contribute to decubitus ulcers are lack of proper ventilation, moisture and diet. Other problems in the past have resulted from body odors created by the patient due to poor or improper ventilation beneath the patient. Additionally the problem of bed wetting and the accumulation of the urine in the bed contribute both to the offensive odor and also to the bed sores of the patient since the moisture remains in the area of the patients body. I
Attempts have been made to remedy these conditions and prevent the decubitus ulcers but these have been unsuccessful. Some have involved merely the passing of air through the bed mattress which air is then allowed to pass upwardly around the patients body. Here the problem of urine accumulation, however, has
not been dealthwith and thus there is no provision for its disposal. Other devices have had pulsatingly inflatable air mattresses which again merely allow the air to be circulated upwardly around the body of the patient.
SUMMARY OF THE INVENTION 7 Applicants novel device for preventing bed sores acts as a complete system to remove from the area of the bedridden patient any urine accumulation and also provide a proper air-oxygen mixture environment sur-- whose central portion is cut out to receive the bed pan member is first positioned'on the bed. The bed pan is next positioned in the cutoutportion of the pad. It has a bottom wall with vertical walls extending upwardly around the periphery 'of the bottom wallwith outwardly extending lips around the .periphe'ryof'the vertical walls. These outwardly extending lips have their top surface seating flush withthe top of the foam pad. A
plurality of laterally spaced hollow platforms extend upwardly from the bottomwall ,with the spaces between the platforms forming drain channels where any urine or other moisture beneath the patient may be accumulated. A drain nozzle formed on one side of the bed pan is connected to a tube having a vacuum exhaust pump attached thereto. In this manner any accumulation of moisture or liquid in the drain channels is automatically sucked out from the area below the patient. Also formed on the bed pan is an air intake nozzle that connects a tube from a source of air and oxygen that is supplied to the bed pan. A unit inserted in this tube may be utilized to vary the mixture of air and oxygen. A perforated cover of plastic is removably placed on top the bed pan with the perforations accomplishing the double purpose-of allowing moisture and liquid to drain downwardly therethrough and also allow the air which is being pumped into the bed pan to rise upwardly around the body of the patient.
DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of applicants therapeutic bed pan unit;
FIG. 2 is a partial top plan view illustrating the bed pan;
FIG. 3 is an enlarged cross section view taken along lines 3-3 of FIG. 2;
FIG. 4 is an enlarged cross section view taken along lines 4-4 of FIG. 2.
DESCRIPTION OF THE PREFERRED EMBODIMENT Referring to the drawings applicants novel device is shown utilized with a normal hospital bed generally designated numeral 10. It has a regular headboard 12, a footboard l4 and connecting cross rails 16. A'mattress 18 is supported thereon. Atop the mattress is a pad 20 made from a foamed plastic material such as polyethylene. e
The foam pad 20 may be formed from an integral sheet having a cutout section 22 in its central portion that matingly receives bed pan 30 or alternatively the pad may be made from components that are seam welded as illustrated along lines 24 and have a cutout section formed inthe center. The area adjacent the top surface of cutout section 22 has a recess 25 formed therein so that lip 32 of the bed pan will have its top surface seated flush with the top of foam pad-20.
Bed pan 30 and its structure are best understood by referring to FIGS. 2 thru 4 which illustrate that it has a bottom wall 34 with vertical walls 30 extending upwardly around the bottom wall. Also a plurality of laterally spaced hollow platforms 38 extend upwardly from said bottom wall with the space between the platforms forming drain channels 40. These platforms are normally flexible so that they have a cushioning effect on the underside of the patient. The number and the shape of these platforms may be varied according to the'amount of weight to be supported by the platforms and also according to manufacturing considerations.
Attached to one ofthe side .walls is an air intake inozzle.
or port 42to which tube 44 is -attached. The opposite end of tube 44 is connected to an air and oxygen mixer 46 which can control theproportions of pressurized oxygen and air to be released into the bed pan. Formed on one of the other vertical walls of the bed pan'is the liquid drain nozzle orlport 48 adjacent'thebottom of the bed pan. Tube 50 is connected to this nozzle with its opposite end being connected to vacuum exhaust 1 a therapeutic effect. The bed pan and the perforated 1. A-therapeutic bed pan unit comprising a bed pan having a bottom wall with vertical walls extending upwardly from around the periphery of said bottom wall, a plurality of laterally spaced platforms extending upwardly from said bottom wall with the spaces between the platforms forming drain channels, a drain nozzle connected to a vertical wall of said bed pan, to exhaust any liquid that accumulates in the bottom of said bed pan, an air intake nozzle connected to one side of said bed pan to supply the interior of said bed pan with air.
2. A therapeutic bed pan unit as recited in claim 1 further comprising exhaust pump means connected to said drain nozzle.
3. A therapeutic bed pan unit as recited in claim 1 further comprising compressed air means connected to said air intake nozzle.
4. A therapeutic bed pan unit as recited in claim 3 wherein said compressed air means comprises an air and oxygen mixer.
5. A therapeutic bed pan unit as recited in claim 1 wherein said bed pan is molded in an integral piece.
6. A therapeutic bed pan unit as recited in claim 5 wherein said platforms are hollow.
7. A therapeutic bed pan unit as recited in claim 6 wherein said bed pan has an outwardly extending lip around the periphery of the vertical walls.
8. A therapeutic bed pan unit as recited in claim 6 wherein said bed pan is made of plastic material.
9. A therapuetic bed pan unit as recited in claim 6 further comprising a perforated cover.
10. A therapeutic bed pan unit as recited in claim 1 further comprising a pad having a cutout section in its central portion that receives said bed pan and which would normally be set upon the top of a bed mattress. II! I!
