Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a medical-surgical collection bag assembly for bodily waste having a fitment that connects the body waste circumferentially to the user and is attached in a sealing relationship to the fitment. It concerns a collection bag that can be removed and removed from the fitment.

Ostomy (artificial opening to the gastrointestinal tract) bags are used to collect fecal matter expelled through a surgically created opening in the abdomen of a patient. One form of bag includes an adhesive ring at the opening of the bag that is used to bond the bag directly to the patient's skin around the stoma or to an adhesive peristal wafer that is adhered to the skin. establish. Two-part ostomy bag assemblies mechanically connect the fitment to the bag in a manner in which the fitment adheres to the user's skin, the bag is separated from this, and is releasable by a relatively rigid bonding element on the bag. It differs from the above in that it is combined with When necessary, the bag can be removed and disposed of by separating it from the fitment, leaving the fitment in place to receive a new bag. The fitment can be left in place for several days before it also needs to be removed. Various forms of two-part assemblies have been proposed. These generally have a bush-on, snap-fit type connection, or some form of separate bag that surrounds the bag material around the bag opening after it has been pushed into the patient's fitment.

These types of assemblies suffer from various disadvantages as they are difficult for the patient to use or cause discomfort during coupling and disassembly. Difficulties in joining and separating the previous assemblies sometimes interfere with the skin seal of the on-body fitment, causing leaks. These bonding materials are also bulky, protrude, and do not bend with movement of the anatomy, causing discomfort.

Another disadvantage is that the bag is not disposable within the flush toilet. This is because the bag material and the relatively rigid bonding ring on the bag pose an obstacle to flushing.

Furthermore, when the bag is disposed of by washing with water, it is necessary to remove air and gas from the bag to prevent it from floating in the bag prior to disposal. According to a typical flush toilet disposable bag that sticks directly to the user's skin, this squeezes the gas out through the waste port and then seals the bag opening by folding the adhesive area around the bag opening in half. This is easily achieved by preventing air from re-entering the bag. When using a rigid coupling ring as in a normal two-part bag assembly, it is not possible to seal the bag in this manner without charge.

It is an object of the invention to provide an improved form of bag assembly.

According to one aspect of the invention, in a bag assembly of the type specified above, the fitment comprises an adhesive layer adhering to the user's skin on the back side of the layer and a plate element adhering to the front side of said adhesive layer. the plate element having a non-adhesive flat front face with a locating collar projecting forward, and a collection bag being inserted into the flat front face of the plate element in use around an opening to the bag; wherein the opening to the bag is positioned relative to the body waste opening by the locating collar.

The collection bag may be flush toilet disposable;
Furthermore, from a flush toilet disposable material having an inner layer of water-resistant material that lies inwardly with respect to the contents of the bag and an outer layer of material that is degraded or dispersed by water in the flush toilet. The bag may have walls that are

This bag has one or more non-adhesive release sheets (this release sheet protects the adhesive area of the collection bag before use, and the part of the release sheet that covers the outer part of this adhesive area) The release sheet can be peeled off from the adhesive area by pulling.

The or each release sheet can be folded back on itself and is preferably circular.

The adhesive area on this collection bag is preferably supported on a flange connected to the bag around an opening in the wall of the bag. This flange may be bonded by an adhesive layer to the inside surface of the wall of the bag, the adhesive layer being exposed around the opening in the wall. Preferably, the height of the locating collar is sufficient to project through the bag opening.

According to another aspect of the invention, there is provided an ostomy bag assembly according to the above-mentioned aspects of the invention, characterized in that the fintment is coupled to the user around the surgically created ostium. .

Two-part flush toilet disposable ostomy bag according to the invention
The assembly and its use will now be described by way of example with reference to the accompanying drawings.

A two-part flush toilet disposable ostomy bag assembly having an adhesive ring assembly according to the present invention will now be described by way of example with reference to the accompanying drawings.

Referring to FIG. 1, the assembly includes a flush toilet disposable ostomy (artificial stoma into the gastrointestinal tract) bag 1 and a stoma 4.
and a user fitment 2 coupled to the user's skin 3 around the user's skin 3. The bag 1 is provided around the opening 11 with a bonding material lO that can be bonded to the fitment 2 and removed from the fitment when necessary, leaving this fitment at the user's location.

Referring now also to FIGS. 2 and 3, parag 1 consists of two flexible strips of flush toilet disposable material joined together along edges 13 to form a sealed bag wall away from opening 11. plastic sheet 1
2, and an intraperitoneal gas vent hole 14 which is filtered as necessary. The materials used to form this sheet 12 are manufactured by Nischmann Bros & Walsh Limited (E
Schmann Bros, & WalshLim
It may be of the type used in the ostomy bags marketed by I ted). This material consists of a thin water-resistant layer 12 that is present on the inside towards the contents of the bag.
A and a thicker outer layer 12B that breaks up or scatters in cold water turbulence so that the inner layer can collapse or break up without becoming an obstruction to the flow. A circular opening 5 is formed in the sheet 12 which contacts the user's body in use.

This bonding material 10 is shown in more detail in FIG. 3 and has an annular reinforcing ring or flange 15 bonded to the inner surface of the seam 12 around the opening 5 by a ring 17 of adhesive material on the front side of the flange. This flange 15 is the seat 12
It is made of a more rigid flexible plastic material and is annular in shape. The outer diameter of this flange 15 is the opening 5 of the seat 12.
The inner diameter of the flange 15 is smaller than this opening, and the central opening of this flange becomes the opening 11 of the bag. The flange 15 has an opening 5 over about half the width.
The inner part of the adhesive ring 17 is also exposed around the opening 11 of the bag. Prior to use,
Place two release sheets 2 on the exposed front part of the adhesive ring 17.
3 and 24.

Each release sheet 23 and 24 is made of a non-adhesive material such as siliconized paper and can be easily removed from the exposed portion of the adhesive ring 17. These sheets 23 and 24 are both
It is annular with a circular center opening having the same diameter as the opening 11,
It has an approximately rectangular shape with rounded corners. Sheets 23 and 24 are folded along a line proximate to the diameter of the sheet;
one half of the sheet overlaps the other; second
As shown, the lower half of each chute releasably adheres to the adhesive ring 17 while the other halves are free. The release sheets 23 and 24 are actually slightly larger than the exposed part of the adhesive ring 17 when unfolded flat, and the folded edges of these sheets overlap each other on the adhesive part, thereby exposing the adhesive part. We guarantee that you will not.

Referring now also to FIGS. 4 and 5, the user fitment 2 is bonded to the user's skin 3 by an adhesive layer in the form of a disc 30 on the back side of the fitment. The disc 30 is rSEEL-APBELJ (Eschmann Bros & Walsh Ltd.).
It consists of a hydrophilic polymer in a supporting matrix of a hydrophobic polymer, such as Limled®. disk 30
is annular with a central opening and is sized to match the size of the small hole 4 of the user. Prior to use, the back surface of the disc 30 is protected with a release sheet 32.

An annular circular plate element 33 is molded from semi-rigid but flexible plastic and adheres to the front side of the disc 30 by an adhesive section 34 on the back side of the plate. The outer diameter of the plate 33 is smaller than the outer diameter of the disc 30 (the exposed periphery of this disc is covered by an annular ring 35 of porous tape thinner than the disc; the outer diameter of the porous ring 35 is is larger than the outer diameter of the disk 30, so the porous ring overlaps the disk around the outer edge of the disk.The back surface of the ring 35 is sticky;
Prior to use, it is protected by an annular release sheet 36 where it overlaps the disc 30.

The plate 33 is approximately Q5 mm thick and has a central opening 37 around which a positioning collar 38 projects forward. The height of the collar 38 from the plate 33 is approximately 3
n++++ and at least high enough to protrude through the binder IO. Its outer diameter is slightly smaller than the diameter of the opening 11 of the flange 15 of the bag binding material 10. Around the outside of the collar 38, the plate 33 has a non-adhesive but firm adhesive layer 17 on the bag binding material lO.
It provides a planar flat front surface 39 with which a releasable sealing connection can be formed.

In use, the user must remove the release sheet 3 from the disc 30.
2, remove the release sheet 36 from the porous ring 35, and smooth the disc and sheet on the skin,
First the fitment 2 is bonded to the skin 3 around the stoma 4. Porous ring 35 helps prevent the outer edge of disc 30 from being removed from the skin.

Next, the user holds the octomy bag 1 with the release sheets 23 and 24 still in place, and places it in contact with the fitment 2, so that the collar 38 is closed to the opening 11 of the 7th puffer.
inside the bag and arrange it accurately so that the bag hangs vertically. The free edges of each release sheet 23, 24 are then gripped alternately and pulled outward parallel to the surface of the bar 1 to peel them off from the center of the adhesive ring 17.

In this way, the lower adhesive portion 17 is exposed and can be brought into contact with the front surface 39 of the plate 33 with gentle pressure.

This provides a secure hold of the bag 1 on the fitment 2 and seals the bond between the bag and the fitment against leakage of bodily waste entering the bag.

When it is necessary to remove bag 1, the user grasps bag 1 and plate 33 together and strips the bag binding material lO from patient fitment 2, leaving this fitment in position on the user's skin. . The bag 1 is then compressed to release air and gas through the opening 11 and the bag is folded over the diameter of the flexible flange 15 such that the surface of the adhesive layer 17 folds over on top of itself to seal the opening. Alternatively, the bag 1 can be sealed in this manner prior to releasing the gas through the vent holes 14 within the abdominal cavity by compression. This effectively prevents air from entering the bag, so that the bag can be dropped into the flush toilet pan with less risk of floating. Fitment 2 only needs to be replaced after a few days.

The thin and flexible nature of the flange 15 and thus of the bonding material 10 ensures trouble-free flushing around the waste pipe of the flush toilet. Since the adhesive portion 17 is also soluble in water, the bag can be easily disposed of.

This type of bag assembly provides a secure bond with a low profile, so that there is no noticeable bulge under the user's clothing. The user portion of this connection can also be flexible so that it conforms to the anatomy.

Various modifications to this assembly are possible. For example, the flange 15 can be connected to the outer surface of the bag. When the bag 1 is adjacent to the patient fitment, the release sheets 23 and 24 are preferably removable, for example by pulling the part of the sheet overlying the outer area of the adhesive, but this can be achieved by a different arrangement of the release sheets. can.

The present invention is not limited to use with flush toilet disposable bags or two-part bags, but can be used with any conventional medical-surgical collection bag.

The present invention is not limited to use with flush toilet disposable bags, but can be used with any conventional two-part medical-surgical collection bag. In this regard, the present invention can also be used in ileal foraminal or urostomy applications.
