Abstract

The invention relates to a prosthesis that can be used to capture and deodorise gases expelled distally from the human digestive tract. The invention comprises at least one tubular part suitable for insertion into the human rectum and including at least one cavity, the main opening therein being turned towards the proximal end of the rectum. The aforementioned cavity can receive gases, faecal matter and secretions from the digestive tract. Said cavity can retain faecal matter and secretions, while allowing gases to pass therethrough towards a deodorisation circuit. The tubular part bears on the walls of the rectum, such as to obstruct the natural gas passage along these walls and to direct said gases towards a deodorisation circuit. The invention comprises a second, ring-shaped part placed outside the body, said ring-shaped part channelling the gases and acting as a bearing point for maintaining the part located inside the rectum in a suitable position. The two parts are connected by a third, tubular flexible part which is involved in the gas capture process. The gases captured in this manner are deodorised by means of physical and chemical absorption and adsorption.

Technique antérieure Prior art
Des dispositifs de désodorisation des gaz du tube digestif équipent certaines poches de colostomie. Cette technique est très efficace mais d'application restreinte. Il existe, par ailleurs, des couches culotte adsorbant les odeurs au moyen de fibres de carbone activé lorsque l'excrétion gazeuse a lieu par la voie normale. L'efficacité de cette dernière technique est limitée par l'étanchéité de la couche culotte. Il existe enfin des dispositifs qui permettant d'éviter le bruit associé à l'excrétion gazeuse par la voie normale. Mais il n'existe pas de dispositif prosthétique permettant de supprimer, de manière sûre, les odeurs associées à l'excrétion gazeuse qui a lieu par la voie normale distale. Gas deodorization devices of the digestive tract equip some colostomy bags. This technique is very effective but of limited application. In addition, there are odor-adsorbing panty layers using activated carbon fibers when the gaseous excretion takes place by the normal route. The effectiveness of the latter technique is limited by the tightness of the diaper. Finally, there are devices that make it possible to avoid the noise associated with gaseous excretion by the normal route. But there is no prosthetic device to safely remove the odors associated with gas excretion that takes place by the distal normal way.

Quatre orifices (n°l à 4) de forme circulaire et de diamètre 4±0,25 mm traversent l'épaisseur du tube. Les cercles formés par ces orifices sont tangents au plan supérieur de la cloison; les axes perpendiculaires au plan de ces cercles forment entre eux un angle d'environ 90°. Les orifices n° l à 4 mettent en communication la cavité haute avec l'extérieur du tube. Deux orifices (n°5 et 6) forment deux cercles de diamètre 2±0,06 mm tangents au plan inférieur de la cloison.

This partition is a cylinder of diameter 22 ± 0.7 mm and height 2 ± 0.06mm. It separates the light inside the tube into a high cavity and a low cavity. Four orifices (nos. 1 to 4) of circular shape and with a diameter of 4 ± 0.25 mm pass through the thickness of the tube. The circles formed by these orifices are tangent to the upper plane of the partition; the axes perpendicular to the plane of these circles form between them an angle of about 90 °. Ports 1 to 4 place the upper cavity in communication with the outside of the tube. Two orifices (nos. 5 and 6) form two circles of diameter 2 ± 0.06 mm tangent to the lower plane of the partition.

The orifice No. 6 is symmetrical with the orifice No. 5 with respect to the vertical plane of the tube. Ports No. 5 and 6 put the low cavity in communication with the outside of the tube.
