GASTROINTESTINAL PROBE Russian patent published in 2000 - IPC

FIELD: medical engineering. SUBSTANCE: device has tube having longitudinal diametric partition in its cavity forming two canals one of which is suction canal having a number of lateral openings and the other one is discharge canal. The tube has the third canal having outlet opening for supplying nutrient or washing solution and end piece mounted on the tube end to be introduced. Waterproof partition is set inside of the tube cavity remote from the tube end to be introduced and outlet opening of the third (feeding) canal, so that the solution does not get into the suction canal opening when the probe is in static state. The longitudinal partition is some distance apart from the transverse partition. The distance is equal to at least half of the tube diameter or has an opening which area is equal to evacuation canal cross-section area. EFFECT: enabled prolonged decompression of any gastroenteric tract segment; enhanced effectiveness in cleaning and concurrently feeding through the same probe; enabled multiple gastric, intestinal, duodenal lavage removing the contents at the same time. 3 dwg
