BEDPAN 5 Sheets-Sheet 3 Filed Feb. 4, 1964 INVENTOR iazzzZ fllfikalsaig,

BY 5M W ATTORNEY United States Patent 3,246,344 BEDPAN Daniel M. Saulson, Rye, N.Y., assignor to H.M.B. Inc., a corporation of Delaware Filed Feb. 4, 1964, Ser. No. 342,420 14 Claims. (Cl. 4-112) This invention relates to bedpans for use by invalids or patients who are for other reasons confined in bed.

Numerous forms of bedpans are known in the prior art and have been employed in actual service, but these, as well known, suffer drawbacks for one reason or another. Among the principal drawbacks encountered in bedpans heretofore employed may be mentioned their unwieldy size; a shape which causes discomfort to the patient occupying the pan in use, and/or which causes the pan to shift, slide or otherwise become displaced from a proper position beneath the patient; and the difficulty as well as dis-com; fort encountered in the use of the pan by a patient in a prone position.

The principal object of the invention is to provide a bedpan which is so constructed as to overcome the foregoing and other objections which attend or are inherent in presently known forms of bedpans.

More particularly, an object of the invention is to provide a bedpan having an anatomical contour such as to eliminate or greatly reduce discomfort to the patient using the same.

Still another object is to provide a bedpan of the character referred to and so constructed as to enable it to be readily slipped into position beneath a patient and which will enable it to remain firmly in place without tendency to shift or slide therefrom.

Another object of the invention is to provide a bedpan an aforesaid, which will enable it to be used by a patient while lying flat on his back, so that the support for patients back will be supplied substantially entirely by the mattress, rather than in part by the pan, requiring the patients back to be arched up.

Yet another object of the invention is to provide a bedpan as aforesaid so constructed as to enable it to be used either by an adult or a child.

Other objects and advantages of the invention will be more apparent from the detailed description and from the accompanying drawings in which:

FIG. 1 is a view in top plan of a bedpan constructed according to the invention;

FIG. 2 is a view taken longitudinally thereof along line 2-2 of FIG. 1;

FIG. 3 is a view of the bedpan is end elevation at the wider end thereof;

FIGS. 4, 5 and 6 are transverse sectional views taken along lines 4-4, '5-5, and 6-6, respectively, of BIG. 1, and looking in the direction of the arrows indicated for each of these views;

FIG. 7 is a view in side elevation, showing the position of the pan when in use by a patient in a prone position;

FIG. 8 is a fragmentary view, in plan, showing a modification of the bedpan shown in FIGS. 1 to 6; and

FIG. 9 is a view taken along line 9-9 of FIG. 8.

The bedpan embodying the invention is of unitary construction and may be formed from metal, such as stainless steel, as well as various other suitable materials. Preferably, however, it is molded, as by blow molding the same, from a synthetic plastic resin, such as high density polyethylene, polypropylene, polystyrene, acrylonitrile-butadiene-styrene copolymer, and the like.

Referring to the drawings, it will be seen that in plan view the bedpan, indicated generally by numeral 5, is of somewhat trapeziform' outline but with the sides thereof, which extend .generally in the direction of the longitudinal axis of the bedpan, being curved as hereinafter more specifically described.

As shown in the drawing, the bedpan of the invention comprises a bottom wall, indicated generally at 10, joined to a relatively wide rear wall 11 and to a relatively narrow forward wall 12, as well as to the side walls, indicated generally by numerals 1'5, 16. Each of the latter walls is joined to the corresponding end of rear wall 11 by a relatively small quarter-round curved portion 15a, 16a. From the outer ends 15b, 16b of the latter, the respective side walls are of longitudinally curved contour as shown at 150, 160, substantially throughout th length of the side walls and extending outwardly with respect to the longitudinally axis of the bedpan. The opposite end 15d, 16d of each thus curved side wall 16, 16 is joined to the corresponding end of forward Wall 12 by a rounded section 152, 16c, respectively.

The sidewalls 15, 16 are preferably curved slightly along the transverse dimension thereof, this curvature being somewhat varied along the longitudinal dimension of the side walls, as shown in FIGS. 3 to 6, inclusive.

In terms of practical dimensions, the bedpan may be of an overall length of between 13 and 14 inches; a width of approximately '12 to 13 inches at the rear end thereof; and a width of approximately 3 inches at the forward end thereof.

As will be seen, particularly from FIG. 2, the bottom wall 10 of the bedpan comprises a portion 18 of somewhat triangular outline disposed substantially in a horizontal plane. This portion extends rearwardly from the forward wall 12 for a major portion of the longitudinal dimension of the bedpan. This horizontal portion 18, of the bottom wall 10 thus serves to support the bedpan in horizontal position. In accordance with the invention, the remaining portion 20 of the bottom wall is of substantially rectangular outline with its major axis at a right angle to the longitudinal axis of the bedpan, and extends from the inner transverse end 21 of the horizontally disposed triangular portion 18 to the rear wall 11. This portion 20 is inclined upwardly at an angle of about 20 to 30 degrees with respect to the horizontal portion 18 of the bottom wall.

Further, in accordance with the invention, rear wall 11 is disposed, throughout the length thereof between the inner ends 15 161 of the quarter round portions 15a, 16a in a plane which extends substantially at a right angle to that of the portion 18 of the bottom wall, and is substantially parallel to the transverse axis of the bedpan, as shown particularly in FIGS. 1, 2 and 3. The fact that rear wall 11 is essentially straight throughout its length provides stability to the bedpan and prevents it from rocking when positioned beneath a patient in a prone position, with the rear wall 11 and portion 20 of the bottom wall pressed (by the weight of the patient) into a bed mattress. This is in marked contrast to bedpan constructions wherein the rear wall and/or the adjoining portions of the bot-tom are rounded transversely of the pan, thus permitting the bedpan to rock when thus positioned.

The length of the rearwall 11, in conjunction with the fact that it is straight substantially throughout the length thereof, i.e., essentially mono-planar, contributes to the stability referred to above, and serves also to increase the cubic contents of the bedpan, Thus, the rear wall 11 may be relatively shallow while nevertheless providing a bedpan of adequate cubic contents.

As shown in FIGS. 1 and 2 the forward wall 12 is preferably likewise disposed in a plane extending substantially at a right angle to that of portion 18 of the-bottom wall, but is preferably slightly curved longitudinally with respect to the transverse axis of the bedpan.

Preferably, as in the modified embodiment shown in FIGS. 8 and 9, the forward wall is provided centrally along the upper edge thereof with a rectangular notch 24 about three-quarters of an inch deep and extending preferably the, full length of this wall. This notch serves to facilitate the pouring or draining of the contents of the bedpan when disposing of the same. This notch, additionally, -serves to simplify manufacture of the bedpan when produced by blow-molding processes.

The top wall of the bedpan, indicated generally by numeral 25, extends inwardly from the rear wall 11 and side walls 15, 16 and slopes downwardly with respect to bottom wall 10, at a relatively small angle from the upper end of the forward wall 12 to the upper end of the rearwall-11.

Thus, as'will be seen particularly from FIGS. 2, 3 and 7, the inclined portion 20 of the bottom wall forms, with rear wall 11 and the rear portion of the top wall 25, a wedge-shaped portion at the rear and relatively wide end of the bedpan.

At its rear, shallow end, this wedge-shaped portion is of a height not substantially in excess of about one and one-half inches, and at its deep end, i.e., atthe line 21, where the triangular portion 18 of the bottom wall joins the rectangular portion 20 thereof, it is of a height of approximately three inches, the height of forward wall 12 being of the order of about three and one-half inches.

The above-described wedge-shaped portion of the bedpan serves several important purposes and advantages. Thus, it enables ready placing of the bedpan under a patient; it avoids the necessity for arching the back of a patient when using the bedpan in a prone position, as shownin FIG. 7; and it enables the support for the patients back, when using the bedpan in that position, to be thereof, and with surfaces 31, 32, 33 whichare inclineddownwardly from the periphery 35 of surface'30 to the outer margin of the top wall,'at which they join the rear and sidewalls. These surfaces 30, 31, 32, 33 are formed so as to be disposed symmetrically with respect to the longitudinal axis of the bedpan. The inner periphery 36 of the curved marginal surface 30 is of a contour to provide a relatively large oval-shaped opening 37 disposed centrally of the bedpanand extending in its longitudinal dimension partly over inclined portion 20 and partly over horizontal portion 18 of the bottom wall 10. 1

Thus, the bedpan may be utilized by a patient either in a sitting position (when the bedpan is disposed in horizontal position on the bottom portion 18) or in a prone position (when the bedpan is disposed at an inclined position and supported on'the inclined portion 20);

The portion of top wall 25 extending along the rear wall 11 is provided centrally thereof with a depression,

indicated generally by numeral 39, which serves to clear 4 the coccyx bone of the patient. This depression extends the entire distance from the rear wall 11 to the edge of the opening 37, and may comprise a rectangular central portion 391: extending in a horizontal plane, bounded by inclined portions 39b.

At its narrow end, the opening 37 terminates in oppositely disposed upwardly and outwardly shaped portions or humped surfaces 40 providing a'throat separating the opening 37 from a relatively smaller, oval-shaped opening 42 which extends rearwardly from forward wall- 12. The opening 42 is bounded by a concavely curved marginal surface 43, joined at its inner end to the humped surfaces 40 and contoured, in conjunction with the dimension and shape of this opening, for comfortable support of a child on the bedpan.

The inner peripheral edge 56 of opening 37 and the inner peripheral edge 45 ofthe smaller opening 42 are provided with downwardly extending relatively shallow lips 50, 51, respectively, to prevent these edges from otherwise pressing and biting into the flesh of the patients buttocks in normal use of the bedpan. The lip 45, in the embodiment shown in FIGS. 8 and 9, terminates at the vertical edges of the notch 24, and in the embodimeut of FIGS. 1 to 6 terminates substantially at the sides of forward wall 12 so as not to extend along the upper edge of that wall. Thus, the lip does not interfere with pouringor draining out. the contents of the bedpan. The lips 50, 51 serve also to impart localized stiffening at the edges 36 and 45 of openings 37 and 42, respectively. In addition,'these lips serve to simplify the trimming and; other manufacturing operations in producing the bedpan.
