A pair of slots in the shell, one upon a surgical removal of the lower part of the pair near each end, below the horizontal mid colon. As a receptacle. if its edges are tightly height of the shell, receive a single broad strip sealed against the abdominal wall, it receives and or belt, threaded through these slots so as to lie holds safely the intestinal discharge from said exteriorly along the wall of the shell, through the orifice until such time as convenience permits the full distance between the slots, and again at each end portion of the shell, beyond the slots,---patient ,to dispose of the same. As a shield it pro tects the region from casual blows, and from the whence the belt passes around the patient’s body, and is secured by any suitable belt-fastening rubbing of clothing. The invention improves upon prior 'devices pro-_ means, such as a buckle. A sheet or sheets of any suitable absorbent maposed for this general purpose,-in comfort, in security and in convenience for the person who is ' terial, placed Within the shell as a lining, extend obliged to live with such a situation. It does this beyond the edges of the shell, all the way around, simply and economically, and does it so securely and intervene between those edges and the wear that it permits the patient to engage in all the or» er’s body, as a sealing pad, against which the thin edges of the shell may be pressed by a suitdinary kinetic activltiesof life. able tightening of the belt. The described rela It is an object to provide both a superior recep tion of the belt, shell and wearer’s body provides tacle structure, and a superior seal, and-a supe rior security thereof. each by coaction with the a coaction whereby the belt extends along the other helping attain the improved emciency for` under slope of the bulge or dome of the shell; 5 10 15 20 each other and for the device as a` whole. 25 The improved sealing engagement between the receptacle and the patient’s body assures, without discomfort, a safe holding of contents. The single-strap up-pressing and in-pressing makes ñrm securement of the receptacle in its 30 said sealing engagement without being subject to Y being disturbed by any ordinary active motions » of the wearer’s body. ' C3 CH 40 The pressing of the stiff walls edgewise to the body of the wearer, with curved extent-conform ing to the wearer’s body curvature gives requisite intensity of pressure to hold the seal perfect. The receptacle has the general shape of an elliptical dome curved around the wearer’s body, with the basal terminus of this dome extending or receding without ceasing to be a part of the bulge or rise of such a dome. In other words, there is no basal flange. These results are attained by making a shell of 45 sheet metal whose thin walls have shape approxi mating that of the surface of a semi-ellipsoid. These edges when in .use will terminate abruptly against the wearer’s body. Instead of being cut straight, as on the plane of the longitudinal axis, their horizontal extent is concave, bowed out 50 ward with respect to that axis, to follow the hori zontal curve of an abdomen. And at the ends of the shell the edge line of up and down extent line, as seen in projection on a vertical plane, is con 55 vex toward the wearer’s body, being bowed in 5 10 15 20 and there it applies pressure upward as well as 25 simultaneously inward against the wearer’s body. The receptacle may be emptied in a convenient and sanitary manner, without the belt falling out of place, by holding the free unbuckled strap-end on the wearer’s under-garment, with an ordinary gn spring pinch clip, While the shell end is held in hand' and tipped outward. Fresh lining may be inserted While the shell is in this tipped position. It is intended that the patent shall cover, by suitable expression in the appended claims, what- 35 ever features of patentable novelty exist in the invention disclosed. In the accompanying drawing: Figure 1 is an elevation showing a device em bodying the invention applied at the abdomen of 40 a person; Figure 2 is a top plan, on an enlarged scale, of the device of Figure 1 with the absorbent mate rial omitted; Figure 3 is a front elevation of the device of 45 Figure 2; Figure 4 is anelevation in section on v4--4 of Figure 1, on an enlarged scale. Referring to the drawing, the receptacle l0' preferably will be a light-weight metal shell hav- 50 ing a modiñed semi-ellipsoid shape. The edges I2 of- the shell have the sharpness of a smoothly cut piece of thin metal, so that under mild pres sure these edges, all around the shell, embed themselves rather deeply in a pad I4 which ab- 55 2 _ 2,117,621 sorbently lines the interior of the shell and which extends beyond the shell edges. 'l‘his pad is rela tively soft, for constituting a cushion between the sharp shell edges and the body of the person using the appliance; and its sharpness favors its deep seating in the cushion with consequent eii'ec tiveness of sealing under a pressure which need _ be only gentle. The shell preferably has length considerably lo greater than its width, and is arranged for its longer dimension to extend horizontally in direc tion around the wearer’s body. 'I'he upper and lower edges have a concave aspect when viewed from above, because they recede medially toward the crest of the bulge, for approximately fitting the curvature of the abdominal region of a per son’s body. 'I‘he short up and down edges at the ends of the shell have a 'convex aspect, when viewed in elevation, because medially they ex tend further from the crest of the bulge in order to reach and to press firmly the abdominal wall, which wall recedes as it proceeds laterally around the person. 'I'he described stiffness with approxi mation of actual ilt to body shape, coupled with 25 the stiifness of edges, permits the edges to be _pressed deeply linto the pad, about equally all the way around, under mild pressure applied' by the narrow part of the wearer’s body, draws the receptacle firmly upward and inward tightly against the soft round surface of the abdomen. Nevertheless, by a mere loosening of the belt, it may be conveniently manipulated on and around the belt, for disposal of contents and for the inserting of a fresh lining pad. ’I'his manipula tion is facilitated by the fact that the belt en gages the receptacle low down on its under slope, permitting a. tilting of the receptacle outward over 10 the loosened belt as a sustaining pivot. Yet these conveniences afforded for this operation de tract nothing from the effectiveness and safety of the device when the belt is tightened against the wearer’s body. The cooperative eifect of the 15 shell edges bedded in the soft pad material assure safety of sealing with a minimum of discomfort. I claim as my invention: l. A colostomy- appliance comprising a domed shell, whose basal edge appears approximately 20 as an ellipse when projected on a surface per pendicular to that axis of the dome which passes through its apex, wherein there are combined the features that, the side walls of the dome are curved so as to reach that basal 'edge at a steep 25 angle to any plane perpendicular to that axis; and the course of said basal edge as seen from said the strap I6; and this assures a suil‘iciently tight axis is a succession of reverse curves, of which seal at every location around the edge when the y those constituting the longer sides of the ellipse shell is bound in place by the belt I6. The convexity of the stiñ shell-receptacle is utilized as a cqacting element in securing- and maintaining the shell in proper position. For this I employ a. broad strap or belt I6, which may be of canvas or other suitably strong material, threaded through pairs of slots I8 provided in follow approximately the line at which the dome sides would be cut by an intersecting cylinder having the size and curvature of a _human trunk and having its axis perpendicular to both the the shell near the ends. These are located in the under slope of the mound which the shell, con there is means on the shell for positioning the belt on the shell asymmetrically of the dome and on that slope thereof -which is lower when the stitutes, below the longitudinal axis of the shell. 40 'I'he belt engages exteriorly against this- under slope-wall of the shell throughout the whole dis tance between the two pairs of slots i8; and en gages exteriorly against each end portion of shell beyond the slots, whence the respective ends of the belt pass around the wearer’s body and are said axis of the dome and the longer axis of the ellipse; and there is a belt adapted to go around 35 the body of a person wearing the appliance; and appliance is being worn, being the slope below 40 the plane through the apex and the longer axis of elliptical projection, whereby tension of the belt applies the shell with inward and upward pressure of its basal edge toward the body of a person wearing it. 45 secured together by any suitable means, such as A 2.
