Serial No. 553,877.

In the production of a commode or bedpan well adaptable to use with an invalids bed of the general type shown by U. S. patents to Fazalerley: 1,208,721 of November 7, 1916; 1,257,072 of February 19, 1918 and 1,545,415 of July 7, 1925, diliiculty has been encountered in providing a light, convenient, easily manufactured, and otherwise'practical structure which will possess an easily cleanable interior of no larger size than needed, and will at the same time possess the relatively large substantially rectangular exterior needed for snug reception between the separated liead, foot and hip-supporting mattress sect-ions of the bed. Diculty has also been encountered in producing a pan upon which` the patient may comfortably lie.

It has been'the primary object of my invention to overcome the above difliculties and in so doing, 1 have devised the novelconstruction 'hereinafter described and claimed and shown in the accompanying drawings, and while said construction is designed primarily for use in beds having separable mattress sections and pan elevators, it could in more shallow form, be well adapted to handpositioning in the customary manner upon a conventional mattress.

Fig. 1 of the accompanying drawings is a top plan view of a bedpan constructed in accordance with my invention. l

VFig. 2 is a vertical longitudinal sectional view on line 2-2 ofy Fig.r1.

Fig. 8 is a perspective view of the seat- `upper edge is suitably secured to the plate 8,

so that the three parts 8, 9, and 10 form aunitary structure.

The top plate 8 which forms a seat upon which the patient lies 'or sits (when reclining) is of substantially rectangular form and is provided with an opening 11, the portions 12 of said plate along opposite sides of said opening and the portions 18 within the rear corners of the plate, being concave. The front end of plate 18 is provided with an integral upwardly projecting horn 14 which is open at its rear and at its lower end and communicates with the opening 11. At opposite sides of the horn 14, the plate 8 is provided with longitudinally convex portions 15V to support the users thighs immediately below the hips. The rear portion of plate 8 is formed with a central longitudinally extending channel 16 which opens upwardly, forwardly and rearwardly, said channel being of suiiicient depth and width to accommodate the bones at the lower end of the spinal column so that said plate will not exert pressure upon the flesh in this region and cause discomfort. The formations 12, 18 and 15 conform substantially in shape to the portions of the body with which they contact and hence the patient may be much more comfortable upon the improved pan and the channel 16 prevents painful pressure, than ordinarily.

The bottom 17 of the inner pan 9, is flat at its front portion but toward its rear, is curved both longitudinally and transversely and inclined slowly toward the rear end of the top plate 8, as seen at 18, being integrally joined to said top plate. The side wall 19 of the pan 9 merges at its rear into the inclined bottom portion 18, but in advance of the latter is inclined inwardly, being integrally joined at its upper edge to the plate 8, between the opening 11 and the peripheral edge of said plate.

The outer pan 10 is of substantially rectangular form and is provided with a side wall 20 whose upper edge is solderedor otherwise secured to the plate 8 along the peripheral edge of the latter, said edge of said plate 8 being preferably provided with a shouldered liange 21 to which said upper edge of the wall 2O is secured. Along the'lines of juncture between the wall 2O and the plate 8 and between the inner pan 9 and said plate 8, fluid-tightness exists, so that no fluid may enter the space between the two pans.

The lower portion of the side wall 19 of the inner pan 9 )referably lies against the side wall 2() to sti en the latter against being accidentally bowed or dented inwardly, and the bottom 17 of said inner pan 9 lies upon the front portion of the bottom 22 of the outer pan 10. The rear portion Q3 of the pan bot-- tom 22, is upwardly arched under the inclined portion 18 of the inner pan 9, the arched formation Q3 extending from side to side of the pan and hence providing a downwardly open recess 24 to accommodate a nurses or other attendants fingers to facilitate handling of the pan, particularly when Sliding the latter from an elevator 25 which zis used for raising or lowering it when the improved pan 1s employed upon a bed of the type above mentioned. The lower corners of the pan 10, at its front and rear, are provided with ribs 26 in the present disclo- 23sure to slidably engage gulde channels 27 on the elevator 25.

Not only does the novel construction herein disclosed, provide a comfortable pan, but it also provides one which may be easily man- 3(yfufactured, easily cleaned and conveniently handled. The inner pan 9 is free from any abrupt corners and is shaped to best permit emptying, the horn 14 being of course used as a discharge spout, as well as means for ss'guiding urine into the pan. The entire structure, both internally and externally, may be quickly, easily and thoroughly cleaned, so that the device may be kept in a constant state of sanitation.

Preferably, the inner pan 9 and the top plate 8 are formed from a single casting of light metal or alloy, but the outer pan may be formed easily from suitable gauge sheet metal, and obviously the entire structure 4S3may be covered with baked enamel or the like,

for appearance as well as cleanliness.

The longitudinally convex portions above described, are transversely concave in the preferred construction. This formation uhas a tendency to keep the thighs close to the horn or hood 14 so that there is no danger of urine splashing from the pan in use.

I claim 1. A bedpan comprising a seat-forming top plate having an opening, an inner pan and an outer pan under said top plate, the inner pan being free from abrupt corners to facilitate cleaning, the two pans being fluidtightly joined along their upper edges to *o said top plate and forming therewith a unitary article.

2. A bedpan comprising a seat-forming top plate having an opening, an inner pan and an outer pan under said top plate, the

' inner pan being free from abrupt corners to facilitate cleaning, one of said pans being integrally joined luid-tiglitly along its upper edge to said top plate, the other pan being formed separately from said top plate but fluid-tightly joined along its upper edge thereto.

3. A bedpan comprising a substantially rectangular seat-forming top plate having an opening, an inner pan whose upper edge is integrally joined fluid-tightly to said top plate between said opening an the peripheral edge of said top plate, the rear portion of the pan bottom being slowly inclined rea-rwardly and all portions of said pan being free from abrupt corners; and an outer substantially rectangular pan fluid-tightly joined along its upper edge to said top plate along the outer edge of the latter.

6. A bedpan comprising a substantially rectangular seat-forming top plate having an opening, an inner pan Whose upper edge is integrally joined fluid-tightly to said top plate between said opening and the outer edge of the plate, and an outer substantially rectangular pan whose upper edge is joined {luid-tightly to said top plate along said outer edge of the latter, the bottom of said inner pan lying at its front portion upon the bottom of said outer pan but at its rear portion inclining slowly toward said top plate, the side wall of said inner pan merging into said inclined rear bottom portion, the portions of said inner pan side wall in advance of said inclined bottom portion being inwardly inclined and at their lower portions lying against the side wall of saidouter pan.
