Device for stool drainage

摘要

The invention is directed to a device for sealing a natural or artificial opening of the large intestine, or the rectum, of a patient, and for occluding same, and/or for removing stool therefrom, particularly for continuous, and/or intermittent irrigation, preferably into an external, bag-like collection container, comprising an inflatable balloon with an approximately annular structure formed from a flat, everted tube section, wherein the outer layer of the everted tube section is provided with a radially enlarged region for insertion into the rectum, and has a region that is tapered relative thereto, and that remains at least regionally outside the rectum during use, the intrarectal balloon section having no functional or spatial connection to the transanal balloon section.

主权项

1. A device for sealing an opening of the colon or rectum of a patient, and for obturating the same and, if required, for removing stool therefrom by a continuous drainage and/or by an intermittent irrigation, into an external, bag-like receptacle, the device comprising:
at least one inflatable balloon having a generally annular ring-shaped structure, formed from a portion of a flat, everted tube with two ends, the tube portion comprising a radially expanded intrarectal balloon segment for insertion into the rectum, and a transanal segment that is tapered with respect to the radially expanded intrarectal balloon segment, and which remains at least regionally outside the rectum during use, wherein said intrarectal balloon segment and said transanal segment have no common compartment, wherein said intrarectal and said transanal segments each comprise drainage parts having a central drainage lumen to permit a continuous drainage and/or intermittent irrigation of a stool from the colon or rectum of a patient, and wherein one end of the two ends of the tube portion is adapted to be everted and passed through the lumen of said intrarectal balloon segment and advanced as an inner layer within a lumen of an outer layer of the tube portion to an end thereof.
