PROCÉDÉ ET APPAREIL POUR COMMANDER LE GONFLEMENT D'UN RÉCIPIENT AU COURS D'UNE PROCÉDURE CHIRURGICALE OU D'UN EXAMEN ET SYSTÈME ET PROCÉDÉ DE GONFLEMENT D'UN RÉCIPIENT
A system for insufflating a vessel in a human or animal body, such as the rectum (2) comprises a compressed air vessel (12) from which air inflating medium is passed through a pressure regulator (13), a flow control valve (16) and an inflating conduit (14) which extends into the rectum (2) through a bore (9) in an endoscope (8). A first pressure sensor (15) located in a leading end (17) of the endoscope (8) monitors the air pressure directly in the rectum (2). A second pressure sensor (23) on a carrier element (25) extends through the bore (9) of the endoscope (8) into the colon (4) for monitoring pressure in the colon (4). A third pressure sensor (30) adjacent a point (37) of a needle (32) introduced into the abdominal cavity (3), through which air which may leak into the abdominal cavity (3) is exhausted, monitors pressure in the abdominal cavity (3). A microcontroller (18) reads signals from the first, second and third pressure sensors (15,23,30) and controls the flow control valve (16) for maintaining the pressure in the rectum (2) at a first predefined pressure, and for preventing pressure in the colon (4) exceeding a second predefined pressure. The microcontroller (18) controls the vacuum pump (36) and may also control the flow control valve (16) in order to avoid the pressure in the abdominal cavity (3) exceeding a third predefined pressure, which would result in the collapse of the rectum (2).L'invention concerne un système de gonflement d'un récipient dans un corps humain ou animal, comme le rectum (2) comprenant un réservoir à air comprimé (12) à partir duquel le moyen de gonflage à air est passé à travers un régulateur de pression (13), une soupape de régulation de débit (16) et un conduit de gonflage (14) qui s'étend dans le rectum (2) à travers un alésage (9) dans un endoscope (8). Un premier capteur de pression (15) situé dans une extrémité avant (17) de l'endoscope (8) surveille la pression de l'air directement dans le rectum (2). Un deuxième capteur
