Abstract

La présente invention concerne un dispositif d'extraction de résidus solides par voie rectale qui permet ladite extraction à l'état de repos chez des patients qui ne peuvent effectuer d'efforts abdominaux, qui ne nécessite pas de déplacement et minimise l'intervention de personnel sanitaire ou d'assistance. Le dispositif comprend, au moins, une tête cylindrique (1) raccordée à un tube cylindrique flexible de conduite (2) dans lequel est inséré un rotor avec une vis sans fin (3) sur un axe également flexible accouplé sur une extrémité au rotor (3) et accouplé sur l'autre extrémité à l'axe d'un moteur rotatif (5) de sorte que ledit rotor (3) tourne autour de son axe actionné par ledit moteur rotatif (5). Le tube de conduite (2) peut être raccordé à un réservoir de résidus (8) avec une valve de vidage (10) et un niveau de remplissage (9), et peut également comprendre des roues (31) et une anse (32) pour permettre son déplacement.
