STOMA RECEIVER WITH A REMOVABLE CLAMPING RING ASSEMBLY FOR USE WITH A DISPOSABLE BAG Filed Sept. 10, 1951 I N V EN TOR. BY We pE/P/PY United States Patent STOMA RECEIVER WITH A REMOVABLE CLAMP- ING RING ASSEMBLY FOR USE WITH A DIS- POSABLE BAG Murle Perry, Minneapolis, Minn.

Application September 10, 1951, Serial No. 245,822

2 Claims. (Cl. 128283) This invention relates generally to stoma receivers, otherwise known as colostomy appliances, and particularly to an appliance constructed to permit a disposable bag to be used.

My present invention is related in many respects to my co-pending application, Serial No. 172,520, filed July 7, 1950, entitled Stoma Receiver, now Patent No. 2,638,898, but is particularly adapted to use a disposable bag to replace the latex rubber bag used in the structure disclosed in said co-pending application.

A principal object of my invention is to provide means for mounting a disposable bag made from waterproof sheet material, such as plastic or paper, on the body of a person having a colostomy or ileostomy opening.

It is another object of my present invention to provide a pair of bag clamping mounting and supporting rings having separable substantially concentric cylindrical segments respectively formed thereon and adapted to sealingly receive the mouth portion of the bag between said segments to securely grip said mouth portion and hold the same in open position while providing an annular reinforced opening adapted to receive from a stoma and cooperate with a foundation ring mounted on the outside thereof to securely hold the mouth of said bag in the desired position.

It is a further object to provide a pair of mounting and supporting rings for a colostomy appliance and adapted to releasably clamp the mouth portion of a disposable bag made from sheet plastic material or the like and hold said mouth in open position and provide annular reinforcement therearound on both the inside and outside thereof to facilitate mounting a foundation or retaining ring on the outside and a removable insert on the inside.

More specifically, it is an object to provide a pair of mounting rings having a pair of sealing flanges respectively fixed in outstanding relation and adapted to interfit one within the other in concentric relation with the mouth portion of a disposable bag clamped therebetween, the outer flange providing a mounting for a foundation or retaining ring adapted for attachment to a belt and the inner ring adapted to sealingly receive an opening insert on the inside thereof to produce an extremely simple yet highly eflicient appliance particularly adapted to use a disposable bag made from thin sheet material such as plastic or paper.

These and other objects and advantages of my invention will more fully appear from the following description made in connection with the accompanying drawings wherein like reference characters refer to the same or similar parts throughout the several views and in which:

Fig. 1 is an exploded perspective view of my complete appliance;

Fig. 2 is a transverse vertical sectional view taken through the upper portion of my appliance and showing the parts thereof in assembled relation;

Fig. 3 is a front perspective view of a completely as- 2,721,553 Patented Oct. 25, 1955 ice sembled appliance embodying my invention and attached to the body of a wearer; and

Fig. 4 is an end elevational view of the sealing means for the lower end of the bag.

As illustrated in the accompanying drawings, I provide an elongated disposable bag 7 made from any suitable waterproof flexible sheet material such as vinyl polyethylene or other plastic material and having an upper mouth portion 7a and a lower open end 7b. The upper mouth portion 7a has a longitudinally disposed cut formed therein and designated by the numeral 70, as best shown in Fig. 1. This cut permits spreading of the mouth portions and facilitates mounting of the clamping or mounting rings therein.

These mounting rings are respectively designated by the numerals 8 and 9 and each has an outwardly extending cylindrical segment respectively designated by the numerals 8a and 9a. The male cylindrical segment 9a is adapted to be concentrically received within the female segment 8a. The two segments are of such relative size as to produce a tight sealing fit when the mouth portion 7a of the bag 7 is inserted therebetween. In other words, the cylindrical segment 9a is sufficiently small to provide clearance to permit the upper mouth portion of the bag when inserted through the ring 8 and cylindrical segment 8a to form a tight sealed connection between the two concentric segments 8a and 9a but not so tight as to tear the sheet material from which the bag is made. The rings 8 and 9 have annular flanges 8b and 9b respectively formed thereon and the lower portion of the flange 9b is cut away to facilitate mounting and removing a bag from said rings as will be brought out hereafter. The upper portion of ring 9 has a key-receiving recess 9c formed therein to permit insertion of a separation key or other article such as a coin between the two ring flanges 8b and 9b and thereby facilitate separation thereof and releasing the bag. An insert 10 having slightly tapered peripheral side portions 10a is provided and has an opening 10b through an intermediate portion thereof. The inside face of said insert 10 is convexly curved in order to permit limited shifting movement of the appliance when the wearer shifts from one position to another While maintaining contact with the body of the wearer surrounding the opening 10b. The portion of the insert surrounding the aperture 10b is adapted to engage the body of the wearer surrounding the colostomy or ileostomy in the conventional manner as brought out in my co-pending application previousl identified.

A foundation or retaining ring 11 having an outwardly extending outer peripheral bead 12 and an outwardly extending concentrically disposed inner cylindrical segment 13 adapted to concentrically receive the outwardly extending segment 8a therewithin. The fit between the segments 13 and 8a is loose enough to permit easy mounting of ring 11 over said segment 8a but close enough to prevent any substantial amount of relative rectilinear shifting movement between the two rings but permitting relative rotational movement. Two diametrically opposed groups of belt anchoring posts 11a are mounted in peripherally spaced relation on the outside of retaining ring 11 and are adapted to receive the respective ends of a pair of retaining belt members 14. Each end of the belts 14 has a post receiving connection element 15 connected therewith. The lower end of the bag 7 is of course open The following is a description of the assembly and installation of my new appliance. The mouth of the bag 7 is spread apart after being inserted through the opening in the larger of the two mounting rings 8 and the smaller mounting ring 9 is then pressed into the larger ring until the two flanges 8b and 9b are disposed in close side by side relationship one to the other with only the thickness of the plastic bag material separating the same. The back portion of the bag is pressed out to provide clearance at the mouth to assist in maintaining a spaced relation between the front and rear portions of the bag at least at the mouth 7a. A plastic insert is then pressed into the inner cylindrical segment 9a in sealed relation thereto. The rear convex face of the insert engages the body of the wearer and permits limited tilting action as the wearer moves from one position to another. The outer retaining ring 11 then receives the bag therethrough and is shifted upwardly so that the cylindrical segment 13 receives the outwardly projecting portion of cylindrical segment 8a and embraces the same to hold the entire structure in substantially predetermined relation on the body of the wearer, the belts 14 being attached thereto to securely anchor the same in place. When the bag is to be removed, the foundation or retaining ring 11 remains attached to the belt and the ring 11 is merely tilted forwardly to permit the bag assembly to be lifted out through said outer ring 11 and a new bag assembly inserted therethrough, The two mounting rings 8 and 9 are then separated by inserting a camming key or coin into the recess 90 to separate the two flanges 8b and 9b. The separation of the two flanges Sb and 9b is materially facilitated by cutting away the lower portion of the flange 9b. This cut away portion permits the diametrically opposed portions of the flanges to be separated without any material shifting movement of the flange portions adjacent said cut away portion. This is caused by shifting the fulcrum about which the ring 9 swings upwardly and reducing the movement of the lower portion of the cylindrical segment 9a relative to the adjacent portion of cylindrical segment 8a. The mounting of the mouth portion 7a of the plastic bag is also facilitated by this cut away portion of flange 9b since the bag material need only be stretched over a relatively small and narrow flange at the lower portion thereof, thus materially reducing the amount of stretching produced and greatly facilitating the concentric interfitting of the male cylindrical segment 9a within the female segment 8a. It is of course possible and obviously convenient for the wearer to carry an extra bag with an extra set of mounting rings mounted thereon to facilitate and permit speedy replacement of the bag.

It will be seen that I have provided an extremely simple, yet highly ingenious and eflicient, appliance for colostomies and ileostomies in which a disposable bag can be effectively employed. It should be noted that the plastic bag of the vinyl polyethylene or other type of plastic sheet material is well adapted for use since it is easily cleaned and can be re-used a number of times before replacement.

It will, of course, be understood that various changes may be made in the form, details, arrangement and proportions of the parts without departing from the scope of my invention which, generally stated, consists in the matter shown and described herein and set forth in the appended claims.

What I claim is:

l. A stoma receiver comprising an inner and an outer bag mounting and supporting ring, each ring having an outwardly extending cylindrical segment and an annular flange element extending radially outwardly around the inner end of the segment, a disposable bag having an open mouth, the open mouth of the bag being disposed around the cylindrical portion of one ring and the cylindrical portion of said one ring being nested within the cylindrical portion of the other ring with the bag clamped tightly therebetween, an annular retaining ring embracing the outwardly extending cylindrical segment of the outer ring and adapted to be anchored to the end portions of a belt to hold the appliance on the body of a wearer, the annular flange element of the inner ring having the lower portion of the outer periphery materially reduced in diameter and having a cam receiving recess formed in the upper portion thereof, the annular flange element of the outer ring being of substantially uniform diameter and being exposed at the upper and lower portions thereof by said lower portion of the flange of the inner ring and said cam recess to facilitate not only the mounting of the rings in clamped position around the mouth of the bag but also the separation of said inner and outer rings.

2. A colostomy appliance comprising a disposable bag constructed of thin pliable waterproof sheet material having an open upper end and a closed lower end, a pair of interfitting mounting rings each consisting of an outwardly extending cylindrical portion with an inner flange portion lying in'a plane at right angles to the respective cylindrical portions, the open mouth of the bag being disposed around the cylindrical portion of one ring and the cylindrical portion of said one ring being nested within the cylindrical portion of the other ring with the bag clamped tightly therebetween, means attaching said rings to a wearers body, an annular insert member having a central aperture to receive a stoma therethrough, said insert member being tightly fitted within said one ring, the inner periphery of said annular insert being smoothly contoured to prevent irritation of a surrounded stoma projecting therethrough, the annular flange element of said one ring having the lower portion of the outer periphery materially reduced in diameter and having a cam receiving recess formed in the upper portion thereof, the annular flange element of the outer ring being of substantilaly uniform diameter and being exposed at the upper and lower portions thereof by said lower portion of the flange of the inner ring and said cam recess to facilitate not only the mounting of the rings in clamped position around the mouth of the bag but also the separation of said inner and outer rings.
