Zusammenfassung:	FIELD: medical equipment. ^ SUBSTANCE: medical gas insufflator has high-pressure source which output is connected with decreasing reduction gear, first and second safety valves and line for supplying gas into cavity. Output of device for gas preparation is connected with pressure stabilizer and gas discharge meter. Output of gas discharge meter is connected with first safety valve, controlled pressure stabilizer and controlled discharge throttle. Output of controlled discharge throttle is connected with controlled valve. Output of safety valve is connected with second safety valve and line for feeding gas into cavity. The latter is made in form of receiver connected with pneumatic toggle switch. Output of receiver is connected with input of comparison circuit. First input of comparison circuit is connected with output of controlled pressure stabilizer. Output of comparison circuit is connected with control input of controlled valve. ^ EFFECT: improved reliability of operation; higher non-volatility. ^ 3 cl, 1 dwg
