FR2501498A1 - Variable dia. meter ostomy plug - has flexible intra-intestinal cylindrical skirt around upper and lower cylinders supporting shaft on which carbon holding plug is mounted - Google Patents

Abstract

The ileostomy plug (1,2,3) is fixed to a supply, deep skirt (12) which fits into the intestinal opening. The plug is connected via a cardan joint (11) to a hollow shaft (4) at the bottom end of which is an active-carbon filled plug (10). A key (13) engages the upper plug and permits it to be rotated to deform the body of the device. The hollow shaft passes through a fixed upper cylinder (5) which engages a lower cylinder (6) via three longitudinal rods (8). A mobile washer (7) is threaded onto the rods and flexible tongues (9) extend between the washer and the lower cylinder. The elements mounted about the hollow shaft (4-9) deform the flexible skirt of the device to fix it inplace in the opening.

Description

 The present invention relates to a new type of artificial anus apparatus, making it possible to obtain both a retention of faeces, and a release of intestinal gases previously deodorized during their passage through the hollow axis of the apparatus, containing a refill of deodorant activated carbon. It is a new anal prosthesis, continuous by intra-intestinal dilation.

Among the known devices aiming at fitting amputated subjects of the rectum, the first made were the collection bags for single use (incontinent methods). Their frequent changes and the adhesive allowing them to be fixed to the skin often led to irritation, sometimes even a skin allergy, requiring almost permanent local care.
There are also devices aimed at ensuring the continence of the artificial anus (continent methods).

 The magnetic anus consists of a metal ring in which is housed a metal frustoconical plug. The break of the ring in the subcutaneous fatty tissue requires surgical time. This implant inevitably entails an infectious risk. Furthermore, since the magnetic attraction force between ring and plug cannot be uniform, due to variations in the thickness of the subcutaneous tissue, there may be areas of strong attraction, with the risk of skin ulceration, or of weak attraction, making this type of device unreliable and unusable in the skinny or obese subject.

 There is an external magnetic obturator based on the same principle, but requiring no surgical time for its break, since the disposable ring is here superficial, having two sides, one adhesive (skin side), the other magnetic (side metal plug). The adhesive can also cause allergic manifestations, the balance between adhesive and magnetic forces being very difficult to obtain, this type of device remains unreliable.

 These different types of device also represent a bulky sheathing encumbrance during the various daily life situations.

 Finally, there is a sphincter prosthesis in the form of a silicone ring placed around the intestine in the subcutaneous tissue, and inflatable thanks to a tube externalized by the skin.

This prosthesis exposes the subject to the same infectious risks seen above. In addition, it does not allow the release of gases generating abdominal pain not distension of the intestine.

The variable diameter articulated external mechanical shutter allows
to avoid these disadvantages. Its installation requires no time
surgical (elimination of the risk of infection), no adhesive on the
skin (elimination of skin risks). Its articulated character thanks
to a universal joint allows permanent adaptation in space (eliminates
risk of discomfort due to congestion). The materials used
being durable and washable, the present invention can be used
daily for several months. The annual cost of this type of ap
similarity is therefore very low compared to that of disposable equipment
existing.

According to a first variant, the portion of the device opposite
gimbal can be increased. Three to four models of mime principle
but of different overall length can thus pair them
subjects of any morphology.

According to a second variant, the axis of the device can be solid
the shutter becomes absolute.

The accompanying drawing is a sectional view of the device being
dilation; it represents the smallest model with hollow axis.

As shown, the device has a super portion
skin and a deep intra-abdominal portion.

The surface portion corresponds to the skin plug, formed of
three pieces: one peripheral 3 in Silastene, the other intermediate
area 2 allowing the rotation of the central part 1, driven by
a removable key 13.

The deep portion includes a gimbal II secured to two cha
pes appended to the central part of the skin plug 1 and to the movable axis 4.

This, passing #ar a fixed upper cylinder 5 and being partial
housed (and locked in translation) in a fixed lower cylinder 6,
can perform an axial rotation movement, independently of the two
cylinders 5 and 6, joined together by three longitu guide rods
dinales 8. A movable washer 7 threaded in its center, articulated with
the threaded peripheral part of the movable axis 4, and crossed by three
longitudinal guide rods 8, provided by its longitudinal translation
the deformation of eight strips 9 (compression or loosening). A skirt
cylindrical in Silastene surrounds the assembly, joining the parts together
3, 5, 6, thanks to three O-rings: upper, medium, lower.

It transmits in its portion between its average toric portions
and less the deformation of the eight strips 9.

The plug, located at the bottom of the assembly, is intended
contain the refill of activated carbon; it puts in communication (in
association with the mobile axis 4 and the central part of the skin plug 1)
intestinal gases with ambient air.

The device, object of the invention, can set up any enteros
tone: either colostomy (colon opening or large intestine to the skin)
and in this case has a hollow axis; either ileostomy (mouth of ileum or small intestine) and in this case has a solid axis.
