SEALING WITH IRIS DIAPHRAGM FOR STOMA CONTAINER Russian patent published in 2015 - IPC A61F5/445 

FIELD: medicine.

SUBSTANCE: invention relates to field of medical equipment, in particular to sealing for stoma container which is sealed by means of diaphragm, contracting like iris, and to stoma container, which contains such sealing. Sealing substrate contains fixing platform, immobile basic element, attached to fixing platform, rotating element, made with possibility of rotation with respect to immobile element, and sealing element. Fixing platform has distal surface, capable of fixation to stoma container, proximal surface, facing user in the process of application, and hole, which has internal border, determining stoma-accepting hole. Sealing element is connected between immobile basic element and rotating element to provide sealing around stoma and determine stoma-sealing hole. Rotation of rotating element with respect to basic element results in application of higher or lower tension to sealing element in such a way that diametrical dimensions of stoma-sealing hole alter from first diameter to second diameter.

EFFECT: claimed sealing element reduces risk of contact of excretions from stoma with skin, with sealing element being able to be applied for different sizes and types of rough skin surfaces around stoma.
