Abstract

An ostomy pouch comprises of first and second chambersA, Bseparated from each other by means of a membrane wall1having at least one hole2.The hole2allows flatulence gas to pass from the first chamberAinto the secondB. A body waste restrictor hood cover3in the second chamber covers the at least one hole2, the hood cover3having an open gas outlet on the lower edge of the hood cover3. The pouch may have at least one appropriately placed filterF1, F2. The pouch may be a one-piece pouch fixed to a body flange7or two pieces with pouch detachable from the flange7. The ostomy pouch may be closed or drainable.

Description

BODY OSTOMY POUCH

The invention relates to ostomy surgical appliance pouch system, worn on the abdomen area of the human body to collect human body waste following surgical reconstructed bowel outlet externalised to the abdomen.

-Such systems are well known, but consistently develop leakages between the skin and appliances when asleep, due to excess flatulence gas build up unable to be released when filters become clogged by body waste. This prevents the filters from being fully functional causing the pouch to inflate with gas, and lift the body flange up and away from the body causing leaks.

The object of this invention is to prevent the filters from being contaminated, and provides extra room for rapid surges of flatulence gas to gather thus giving the filters more time to release the gas through dry effective filters, preventing the pouch from inflating into the tight balloon that causes leaks to occur when the body flange lifts away from the skin.

This invention provides two separate pouch chambers bonded together as one single pouch system, with an appropriate size hole/s in the partition wall that separates the two chambers, thus allowing flatulent gas to pass Through from one chamber A into the second chamber B, leaving the body waste behind to store in. the first chamber A. Thus keeping the filters dry in the second chamber B, by not having contact with the body waste. The second chamber B will serve an additional support in providing extra accommodating room for large volumes of flatulent gas surges common in sleep after the evening meal, assisting the filters with extra time to release the gas before the pouch over inflates. When deflated, the twin pouch * system will lay flat with a surface area equal to any standard pouch system, to a comfortable size that can be worn discretely under clothing for normal daytime use.

With the pouch's added ability to expand like a bellow, provides extra positions for several more filters to be added if needed to enhance rapid gas release. This invention can be for the ileostomy user with a drainable outlet as used for the liquefied body waste, or for the colostomy user with a two piece closed pouch system for firmer body waste to be emptied through the opening of the pouch and body flange. The pouch can be made in any new flexible, water tight, non allergic material, or the standard plastic or latex rubber used in the majority of ostomy systems.

FIGURE 1 is a side view of the ostomy pouch with chamber A and B inflated with dashed directional arrows of the flatulence gas and a solid directional arrow line for the body waste.

FIGURE 2 shows chamber A, and chamber B, separated and opened to reveal the shared inner membrane wall, containing the restrictor hood, and passage hole.

FIGURE 3 shows a view from above the pouch with chamber A, and B, inflated to show the filter positions.

FIGURE 4 shows a view from the rear where lay the body adhesive flange that attaches to the abdomen.

FIGURE 5 shows a side view with chamber A and B deflated.

FIGURE 6 shows a view of the front side of the pouch (furthest from the body).

As shown in Figure 1, the pouch consists of two chambers A & B sharing a partition membrane wall 1. The partition waIl 1 has an appropriate size hole or multiple holes 2 with a body waste réstrictor hood 3 to prevent body waste making an easy entry into chamber B. Flatulence gas 4 can enter chamber B through the gas passage hole/s 2 for the gas to descend down and out through the open end of the waste restrictor hood 3, to fully enter chamber B where the gas will flow to filters Fl & F2.

Filters Fl & F2 are ideally placed in the upper region of chamber B for the greatest effect & fullest protection by the.hood. If needed extra fiters maybe added to chamber B or positioned on chamber A. Body waste 6 enters chamber A from the flange inlet 7 that fits over the surgically made opening on the abdomen. The body waste 6 drops into the bottom of chamber A to be gathered until appropriate time to empty the contents through the clipped opening 5.

Figure 2 shows chamber A, and chamber B, cut and open to reveal the shared inner membrane wall 1 (diagonal shaded), which contains the gas passage hole 2 (dashed circle), with the semi circle body waste restrictor hood 3. More than one hole 2 and hood 3 can be placed on the membrane wall 1 if considered to be beneficial to the gas flow.

Figure 3 shows a view from above the two chamber's A & B, with the pouch expanded revealing the bellow effect that allows the two Chambers A & B to expand independently of each other. The two filters Fl & F2 protected from contamination body waste can be seen positioned on chamber B. There is room on chamber B for extra placed filters if needed, and if desired also on chamber A in the top bellow pleats.

Figure 4 shows the rear view of the body flange 7 on chamber A with the central opening 8 that sit's over the abdomen surgically made stoma opening.

Figure 5 shows the whole system deflated with the bellow effect concertinaed to allow discrete daytime wearing.

Figure 6 is a front view of the system showing chamber B with filter F2, with chamber A sitting directly beneath chamber B.

Claims

CLAIMS1. A surgical body appliance, to collect faeces body waste in a pouch consisting of two chambers separated by a membrane wall containing a single or multiple holes, enables the flatulence gas to pass freely from one chamber into the second chamber free of any body waste residue.
2. A surgical body appliance as claimed in claim 1 with a body waste restrictor hood cover in the second chamber placed over the single or multiple holes with an open gas outlet on the lower edge of the hood cover allowing gas to pass through the hole into the hood, for gas to descend down and out of the bottom of the hood into the chamber.
3. A surgical body appliance as claimed in claim 3 with filters appropriately positioned to filter out flatulence gas.
4. A surgical body appliance as claimed in claim 4 that can be a one piece pouch fixed to the body flange or two pieces with pouch detachable from the body flange.
5. A surgical body appliance as claimed in claim 5 with a closed non drainable outlet on the pouch for colostomy wearer, or with a drainable outlet and sealing clip for the ileostomy wearer.
6. A surgical body pouch system as claimed in any proceeding claim which is made from flexible, water tight plastic or Latex rubber or maybe a combination of the two with approved non allergenic adhesive to adhere the body flange to the body skin.
7. A twin chamber surgical body pouch substantially as herein described and illustrated in the accompanying drawings.
