Title: INSUFFLATOR
Abstract:
Provided is an insufflator capable of detecting collapse of an RTPS tube without newly providing an expensive air pressure component and without performing air supply. An insufflator (1) comprises: an air supply tube (13) in communication with a carbon dioxide gas tank (11) for supplying a prescribed gas to a patient's body cavity; an electropneumatic proportional valve (3) for adjusting air supply flow rate; and a pressure gauge (8) connected to the air supply tube (13). The insufflator (1) also comprises: an RTPS tube (15) for measuring the pressure inside the patient's body cavity; an RTPS connector (14) to be connected to the RTPS tube (15); a pressure gauge (9) connected to the RTPS connector (14) via a relay conduit (21); and a small hole (18) provided between the RTPS tube (15) and the relay conduit (21) to bring gas inside the conduit into communication with the outside.
