BEDPAN Filed Dec. 11, 1959 \BY HA RR/J, K/ECH, F05 R HARR/J 01? THE F/PM Patented June 17, 1941 warren STATES ear NT o'rrics This invention relates to bedpans.

A satisfactory 'bedpan will possess a number of desirable characteristics, It will be comfortable for the patient. It will have a reservoir from which the contents will not easily spill. It 2 'wiil'be soconstructed that it will receive the ex- {cretal liquids of the patient and conduct them to the reservoir without the loss of any portion thereof upon the bedor, the body'of the patient. It will be easy to empty after use. It will be light in weight. The surfaces exposed to the-liquid will be non-absorbent. It will be easy to clean. -\lfhen not in use, it will be collapsible toasmaller size and capable of ready storage. It will be inexpensive of manufacture and sufficiently sturdyto support the weight of the patient. It will preferably be of one-piece construction to promote ease of handling. It will be capable of ready placement for use and subsequent removal.

This invention provides a bedpan possessing each one of these characteristics, and possessing them all ina single article of manufacture.

The principal parts of the bedpan are the base plate H, preferably made of hard rubber, or other suitable inflexible plastic material, a receptacle l2, and a shield t3. The base plate 1! -=is of -'a generally oval configuration, and is provided at its front end with an eye M by which 22, a hat centrally and downwardly inclined top a A gap l9 between horns 20 and 2| of duct 33.

wall 23, an outside, preferably convexed, wall M,

' and an inside concave wall 25.

The web iii-connects inner edges 26 of the bottom wall 22 and is in effect a continuation of the bottom wall. -The web F8 is integrally molded and vulcaniza-bly joined at its periphery with the cushion H, and forms with the cushion a reservoir 21 for holding the excretal matter of the patient. The inside wall 25 of the cushion 1-1 is made concave so that liquid within the reservoir '21 is less likely to be splashed outside of the receptacle 12. The bottom wall 22 of the cushion and the web i8 are firmly secured. to the upper -face of the base plate ll by the use of a suitable cement, or by any other satisfactory means. A rubber tube :28 is "attached at its one end to the outside wall '24 of :the cushion l1, and is provided at its other end with valved air syringe bulb 2-9, the tube and bulb being provided for the purpose of manuallyinhating the cushion "l 'lwith air.

The shield 13 is an integral extension of the web t8. Its lower portion '30 is .shaped to-fit between the horns .20 and 2| of the cushion "I1 and is united in the process of molding to the .iorward upright end edges of the inside walls 25 of the tubular cushion ill. The :shield is formed with a neck portion 31 immediatelyia'bove the lower portion 30, and broadens intoawider upper portion 32 which .is curved rearwardly in a horizontal direction to lie over the pelvic portion of the body of the patient. On the inner rear face of the shield I3 is secured a rubber This duct is formed by vulcanizing the longitudinal edges of :a strip of soft flexible rubber to the inner face-of the shield along vertical lines spacediashort distance from and-on either side of the central longitudinal line 34 of the shield 13. An upper end opening 35 of the-duct is positioned to properly :receive excretal liquids from the patient and .a lower end opening .36 is disposed in the reservoir at -a point slightly above the level'of the web 18.

Preferably the bedpan is made in different forms, .one for the use of male patients andthe other for the use of female patients, the upper end opening 35 of the duct 33 being suitably shaped and disposed in .each of the two forms.

When the cushion .ll'lis deflated, theshield l3 lies with its inner face resting against the upper Wall 23 of the cushion as shown in Fig. 5, :and with the tube 33 nesting in the space between the two sides .of the deflated cushion. When the tubular cushion H is inflated with :ai-r, =the inside walls 25 assume anwupright position causmade of rubber, a relatively light material.

ing the lower portion 30 of the shield [3 to also assume an upright position. The lower end of the tube 33 which is secured to the lower portion 30 of the shield is thereby brought to an upright position, causing the entire tube 33 to be moved to an upright position, carrying with it the neck portion 3| and the upper portion 32 of the shield l3. When the cushion I1 is inflated, the tube 33 acts as a reinforcing stiffener for the shield maintaining it in its upright position and placing the tube 33 itself in proper utility relationship with the patient. Although, if unacted upon by outside forces, the shield l3 will stand in the position shown in Fig. 1, it may be manually bent forward about the line 31, as shown in Fig. 2, for the purpose of readily emptying the receptacle 2! of its contents after use by the patient.

A bedpan constructed in accordance with this invention is comfortable, the air cushion ll being well adapted to yieldably conform to the body of the patient. The concave character of the inside wall 21 of the cushion l1 prevents accidental spilling of the contents and at the same their passing over the side or rear portions of the top wall 23, over which it would be difficult to pour the contents in a desirably narrow stream. The bedpan is light in weight being In collapsed form it is easy to store either singly or in quantities. Therubber is non-absorbent and there are no cracks or corners diflicult to clean. The rubber material is inexpensive and the molding and vulcanizing process by which the bedpan is given form is likewise inexpensive to practise. Though the tubular cushion I! is comfortable to the patient, the air pressure within it enables it to sustain the weight of the patient. The duct It prevents excretal liquid from coming in contact with the body of the patient or from being accidentally discharged beyond the sides of the bedpan and conducts these liquids safely to the central receptacle of the bedpan. The bedpan is a one-piece article, having no separable parts to become displaced in use, or to become lost. Since its body-supporting part is of low and even elevation above the base plate, it is readily placed for use and removed after use.

The bedpan shown in the drawing and de scribed herein embodies this invention. It is apparent, however, that many slight modifications of the relative dimensions of the shape and of the construction and material of the several parts of the bedpan and of assembling and securing together of the parts may be made without the resulting product being outside of the scope of this invention.

The word rubber as used herein is intended to cover any material having the qualities of pliability, flexibility, imperviousness to liquid and surface smoothness, and lightness of weight of rubber.
