OSTOMY APPLIANCE
This invention relates to an ostomy appliance for collecting body wastes emitted from a stoma of a person having a colostomy or ileostomy.
Heretofore the ostomy appliances for collect-ing body wastes which were commercially successful and, therefore, available to use by the general public have been characterized by features which cause discomfort and inconvenience to the user. Such appliances, for example, require an adhesive patch on the abdomen of the user around the stoma for supporting a pouch through some retaining fixture. Those adhesive patches are directly subject to body fluids which tend to loosen the adhesive to cause leaks and further to corrode the skin to produce severe skin irritation. The collection pouches of such devices generally have inade~uate capacity for overnight usage or even for many normal daytime activities. Further, such pouches tend to produce unsightly bulges under the user's clothing.
Further, the nature of the attachment of the appliance to the user made it difficult to remove the appliance for cleaning or changing it.
It is, therefore, a general object of the invention to provide an ostomy appliance which requires no adhesive attachment for most of the users at least for most of their ackivikies. It is a further object ,~
of the invention to provide such an appliance with a large waste capacity and which at the same time is readily concealed by the user's c]othing. Another object of this invention is to provide such an appliance which is very easily applied or removed without dis-comfort or inconvenience to the user. The invention is carried out by providing an O~ring for seating against and sealing around the stoma of the user, a sealing ring in sealing engagement with the O-ring and supporting a waste collection pouch having an opening aligned with the O-ring to receive waste material from the stoma, and a belt attached to the sealing ring for securing the appliance to the body of the user.
The above and other advantages will be made more apparent from the following specification taken in conjunction with the accompanying drawings wherein like reference numerals refer to like parts and wherein:
Figure 1 is a front view of a waste collection pouch according to the invention attached to the body of the user;

OSTOMY APPLIANCE
This invention relates to an ostomy appliance for collecting body wastes emitted from a stoma of a person having a colostomy or ileostomy.

Figure 1 reveals the ostomy appliance accord-ing to the invention worn by a user. A pouch 10 is secured to a belt 12 by buttons 14. The buttons 14 are each secured to a loop (not shown) which slides on the belt 12. The upper edge of the pouch 10 covers the stoma 16 in the abdomen of the user, as shown in dotted lines. The location of a drain tube 18 at the lower extremity of the pouch 10 is shown by dotted lines. The pouch is an apron style which extends across the entire width of the user's abdomen and extends straight down ~ over about half the abdomen and then terminates in a ; generally V-shaped lower portion. The broken lines 19
2~ in Figure 1 indica~e the fluid level in the pouch when filled to the maximum capacity~of typical previously available pouches. Thus, the maximum capacity of the instant pouch is far greater than the typical pouches and indeed is sufficient to permit wearing the pouch for overnight usage~ The pouch configuration allows the fluid to drain away fxom the stoma and to avoid pressurizing the stoma whether the user is standing, supine or lying on either side. Due to the large area of the pouch, it can provide a large capacity without forming an appreciable bulge.
As shown in Figures 2 and 3 by cross~sectional views, the stoma 16 protruding from the abdomen of the user is surrounded by an O ring seal 20 which sealingly engages the sides of the stoma 16 as well as the abdomi-nal skin. The O-ring is very compliant in order to conform to khe body tissues and provide a tight seal.
As shown, the O-ring is hollow and filled with a gas such as air or other inert fluid. A typical O-ring is composed of hygienic latex or butyl rubber and has an outer diameter of 3.9 cm, an inner diameter of 1.9 cm and has an oval cross-section, as shown, with diameters of 1 cm and 1.25 cm. The wall thickness is 0.5 mm although preferably the side of the ring which contacts the body is about 1~5 mm thick. Alternatively, the O-ring is composed of a solid pliant material such as a highl~ plasticized polyvinyl chloride (PVC).
The pouch 10 comprises an outer panel 22 and an inner panel 24 both formed of 2 mm thick PVC and which is heat sealed around the pouch periphery. An inlet opening 26 is formed in the inner panel and the inner panel is secured by heat sealing at the periphery of the opening 26 to a PVC strap 28 and a PVC pouch sealing ring 30. The strap 28 has left and right ends extending to stainless steel or nylon belt adjusters 32 for attachment to the belt 12. The belt preferably is a nylon reinforced elastic fabric. The strap includes an opening coincident with the inlet opening 26. rrhe sealing ring 30 has a washer portion 34 formed of an annular ring concentric with the inlet opening 26 and has a laterally extending annular flange 36 which pro-jects toward the abdomen of the user and is dimensionedto sealingly engage the O-ring 20. The inner side of the washer 34 also engages the O-ring 20 to form a seal at that point during noxmal usage. Thus, only the small area of the O-ring 20 between the stoma 16 and the washer portion 34 is in contact with the body waste mat~rial which flows through the inlet opening 26 into the pouch 10 . ; `
rrhe strap 28 which is held in light tension by the belt 12 forms an angle with the plane of the washer portion 36 at the point of attachment thereto to thereby urge the sealing ring 30 and the O-ring 20 toward the ~44~B
abdomen to ensure the sealing contact between the O-ring 20 and the stoma 16 as well as the contact be-tween the O-ring and the skin of the abdomen. As shown in the drawings, the pressure of the O-ring 20 against the abdomen results in a slight depression of the abdominal wall. In the event the pouch 10 becomes filled with fluid to cause an over pressure situation, the O-ring 20 acts as a piston slidable in the sealing ring. As the pouch pressure increases, the O-ring 20 is forced to slide away from the washer portion 34 as shown in Figure 4. That action tends to push the sealing ring 30 away from the abdomen to increase the angle of the strap 28 with respect to the washer portion 34, thereby increasing the force exerted by the strap 28 on the sealing ring which force, in turn, is transferred to the O-ring 20 to increase the sealing contact to the stoma and abdominal skin to prevent leakage during the over pressure condition. Thus, the connection of the ostomy appliance to the body of the user is a dynamic one and allows a light, comfortable pressure to be applied by the belt to keep the appliance snug during ordinary conditions, however, it causes a higher pressure to be exerted when needed during high capacity conditions.
Emptying of the pouch is accomplished through a drain tube 18 as shown in Figures 3 and 5 which is stopped by a removable polyethylene plug 40. The drain tube 18 is formed of plastic tubing, ~or ~xample~ sonic welded to the rear panel 24 around the periphery of a drain aperture. A lanyard 38 comprising a short poly~
ethylene strap is also welded at the interface of the tube 18 and the pouch panel at one end or tightl~ fits over the tube 18 and has the other end formed in an eyelet which is engaged in a groove 44 in the outer end of the drain plug 40. The plug 40 has a spherical head 46 of larger diameter than the inner diameter of the tube 18 so that the spherical head when forced into the tubing provides a tiyht secure fit. An enlarged body portion 48 of the plug defines a shoulder 50 which engages the outer end of the tube 18 to provide a positioning stop. The shoulder further serves as a pivot point when the plug is tilted relative to the tube to remove the spherical head from the tube, as shown in Figure 5. Thus, although the plug is very tightly seated in the tubing 18, it is readily removed by the tilting action. The user when emptying the pouch can remove the drain plug with one hand while using the other hand to squeeze the front panel 22 against the drain aperture to control the discharge upon plug removal.
The stoma 16 in most users is structured to protrude slightly from the abdomen and coacts with the O-ring 20 to help hold the appliance in the proper posi-tion. Thus, for most people and for most daily activi-ties, the appliance stays in the correct position without an~ adhesive attachments to the skin. However, in those cases where the stoma does not pratrude sufficiently to help the O-ring in place and for use during rigorous exercise, a guide ring is use~ul to maintain alignment - with the stoma. As shown in Figure 6, a PVC guide ring 52 mounted on an adhesive foam diaphragm 54 is secured to the skin concentrically with the stoma 16 by adhesive 55. The guide ring has an inner diameter slightly lar~er than the outside diameter of the sealing ring 30. The sealing ring then its within the guide ring to pro~ide a stable location of the appliance. Since the O-ring 2a seals around the stoma and prevents seepage of the body fluids onto the area covered by the adhesive matqrial, the fluid cannot attack the adhesive or the skin under-neath as is the case for those appliances which use the adhesive patch as a fluid interface part of the sealing system.
Figure 7 is an exploded view of another embodiment of the ostomy appliance which differs from that described above in the configuration of the belt portion. Here the belt 12' has fixed loops to engage hooks 56 removably connected to the strap 28. A single belt adjuster 32' located at the back of the user joins two parts of the belt 12' in an adjustable fashion. Two buttons 14 are mounted on the belt parts 12' to engage buttonholes 14' formed in the pouch 10. By forming the belt 12' of elastic material, the belt can be so dimen-sioned that when a proper amount of tension has been applied to the belt the buttons 14 will be separated the proper distance to align with the buttonholes 14'.
In Figure 8, another means o~ securing the -sealing ring to the belt is shown. A sealing ring 30' has a pair of integral arms 60 secured to the top thereof and extending laterally and downwardly to ~orm a hook at each side of the sealing ring 30' for direct attachment to fixed belt end loops. Thus, the separate strap ~8 is eliminated~ This embodiment is especailly useful for incorporation into the Figure 7 embodiment hut is not limi~ed to that version of the appliance.
Figure 9 illustrates a vertical slit 62 in the upper corner of the pouch 10 instead of the button-hole 14'. The slit is long enough to allow the belt 12 to be threaded through the slit thereby providing support for the pouch corners without using bu-ttons. This is readily incorporated into the Figure 1 embodiment but is not limited thereto.
It will thus be seen that the ostomy appliance according to this invention provides greater comfort, cleanliness and convenience and a less obtrusive bulge under the user's clothing than do other generally avail-able ostomy appliances.
As shown in Figures 2 and 3 by cross~sectional views, the stoma 16 protruding from the abdomen of the user is surrounded by an O ring seal 20 which sealingly engages the sides of the stoma 16 as well as the abdomi-nal skin.
