' INVENTORS. ROBERT N. HERGATT a BYMERVIN P. HA E ATTORNEYS United States Patent 3,943,306 BGBY WASTE RECEPTOR APPLIANCE Robert N. Hergatt, Box 82, Pavonia, Ohio, and
' Mervin 1. Hale, Rte. 2, Mansfield, Ohio Filed Apr. 8, 1959, Ser. No. 894,962 4- Claims. (Cl. 128-433) The invention relates generally to waste receptors adapted to be worn by a person who has undergone an operation such as a colostomy, ileostomy or nepbrostomy, and whose body waste is thereafter discharged through an incision in the abdominal Wall sometimes called a rosette.
Prior devices for this purpose have provided means for holding the mouth of a disposable bag over the incision or rosette, but all of such devices of which we are aware have failed to meet one or more of the requirements necessary to provide an effective device capable of being satisfactorily and comfortably worn for substantial periods of time.
The improved device of the present invention is small and compact, comfortable and inconspicuous to wear, provides a seal with the body around the rosette while allowing the skin at the seal to breathe, and provides a positive seal with the mouth of a disposable bag.
An important object of the invention is to provide an improved construction which utilizes the pressure of a body-encircling belt to effect a positive seal between the mouth of a disposable bag and a ring sealing member held against the body.
A further object is to provide a novel bag holding colostomy device in which the bag may be removed and replaced Without removing the device from the body.
Other objects are to provide a novel bag holding colostomy device which requires only one supporting belt, which requires no spring clamping means to seal the mouth of the bag, which has all its parts capable of sterilization, and which uses ordinary open-mouth disposable plastic bags.
A still further object is to provide a novel bag holding colostomy device having a sealing ring with an annularbody sealing groove on its inner end and a tapered bagsealing flange on its outer end, and breather holes connecting the sealing groove with the atmosphere.
These and other objects are accomplished by the improvements comprising the present invention, preferred embodiments of which are shown by way of example in the accompaying drawing and hereinafter described in detail. While the best known modes of carrying out the invention are disclosed herein, it will be understood the various modifications and changes in details of construction are comprehended within the scope of the invention as defined in the appended claims.
Referring to the drawing:
FIG. 1 is a perspective view of the improved device as positioned upon the body of a wearer.
FIG. 2 is an enlarged sectional view as online 22 of FIG. 1.
FIG. 3 is a side elevation of the assembled device with the belt removed.
FIG. 4 is an exploded perspective View.
FIG. 5 is a view similar to FIG. 2 of a modification.
The extreme compactness and simplicity of the improved device are apparent from the fact that its parts comprise just two wedge fitting rings, a bag and a belt. The sealingring 16 and clamping ring 11 may both be made of a suitable rigid plastic material such as Lucite, or other suitable material not corroded or attacked by body fluids, and easily sterilized by washing in soap and hot water. Thebag 12 is preferably an ordinary tubular flexible polyethylene bag having oneend 13 sealed shut and anopen mouth 14 at the other end.

Thebelt 15 may be of fabric or nylon or any suitable material, preferably a material which is easily cleaned or sterilized.
The sealingring 10* has ashouldered base portion 16 formed with anannular groove 17 in its end face for contacting the flesh F of the wearer around therosette 13 through the abdominal wall. From thebase portion 16, anannular flange 19 extends outwardly of the body and the outer annular surface of the flange is tapered convergingly on the order of 2 to 10. Obviously, the diameter of thering 10 ,can be varied according to the size of therosette 18 which it is to surround, and the ring is preferably sized to fit standard sizes ofbags 12.
Thegrooved surface 17 provides for making a tight non-skid sealing contact with the Wearers skin when the ring is gently pressed against the body by thebelt 15. However, since the device may be worn over long periods of time, it is desirable to relieve the suction efiect within the groove to permit the skin to breathe and prevent the development of sores or skin irritation. To this end a fewtiny breather holes 20 are provided in theshouldered portion 16 connecting thegroove 17 with the atmosphere outside of thering 10. Theseholes 20 do not interfere with the seal between the inner edge of thegroove 17 and the body, so that gases within the ring cannot escape, but ordinarily flexing of the body will cause a slight breathing or pulsating effect within thegroove 17 and consequent circulation of air through thebreather holes 20.
The clamping ring 11 is substantially narrower than theflange portion 19 ofring 10 in a direction axially thereof, and its innerannular surface 22 is tapered to match the outer tapered surface offlange 19 to make a sliding wedge fit therewith. Thus, by forcing the ring 11 inwardly on theflange 19, with themouth 14 of a snugly fitting bag between the two tapered surfaces, a tight seal is effected between thering 10 and the mouth of the bag.
At diametrically opposite locations, the clamping ring 11 is provided with U-shapedmetal clips 24 having their ends embedded into the material of the ring, and adapted for attachment to the ends of thebelt 15. One end of the belt preferably has a hook 25- attached thereto for detachably engaging one of theclips 24, and the other end is attached to the other clip by means of anadjusting loop 26 for adjusting the length of the belt in a usual manner.
When the ends of the belt are attached to theclips 24 as indicated in FIG. 2, the tension of the belt exerts an inward pressure on clamping ring 11 to wedgably clamp the mouth ofbag 12 between the matching tapered surfaces of the rings 16' and 11, and tightly seal the mouth of the bag against the escape of liquids or gases. This same inward pressure tightly seals the inner edge of theshouldered portion 16 ofring 10 against the wearers skin to prevent the escape of liquids or gases at that point, by partially folding the skin into theannular groove 17, wherein the suction effect is relieved by thebreather holes 20, as previously described.
In the modified form of device shown in FIG. 5, the sealing ring 116 has no annular shouldered portion with an annular groove contacting the body. The ring has an outer tapered surface matching the inner tapered surface of the clamping ring 111 which is provided with thebelt clips 124 so that themonth 114 ofbag 112 is wedgably clamped between the matching tapered surfaces by the tension of the belt.
It will be apparent that the device is so compact as to be comfortable and inconspicuous when worn under clothing, and that the two rings constituting, with the belt, the permanent essential parts of the device are easily disassembled and sterilized. No bacteria-breeding absorbent pads, are required.
To apply the improved device, the clamping ring 11 is first slid over the mouth of thebag 12 to a position thering 10 centered over the rosette, thehook 25 is engagedinthe clip 24 opposite to the clip engaged by theloop 26, the tension of the belt being adjusted to exert a slight amount of inward pressure on therings 10 and 11.
The gentle inward pressure of the belt upon the matching tapered surfaces of the sealing and clamping rings insures a positive seal at all times between the .bag and the sealing ring and between the sealing ring and the body. However, the bag can easily be removed at'any time'by pushing outwardly with the fingers on the inner edge of clamping ring 11 at diametrically opposite points to release the mouth of the bag. Thus,'the device does not need to be removed from the body to remove and replacethe bag; v V
The improved device provides an extremely simple, compact and inconspicuous body waste receptor for use following colostomy and the like operations, which device w V is easy, eflective and comfortable to use over long periods and adapted for'complete cleansing and sterilization before re-use.
