First Claim
1. System for heated gas insufflation in patients, comprising:
- —
an insufflator (1) provided with;
a gas inlet (2), a valve (3) that regulates the flow of gas to be supplied, an adjustable heater (4) for the gas to be supplied, a sensor (5) that detects the temperature of the heated gas, an outlet (6) for supplying the gas, and means (7) for propelling the gas toward the supply outlet (6) and;
a disposable supply duct (8), that may be coupled to the gas outlet (6) of the insufflator in order to convey the gas, heated and supplied by the insufflator (1), into a patient'"'"'s cavity;
characterized in that;

Abstract
A system includes an insufflator provided with a gas inlet, a valve that regulates the flow to be supplied, an adjustable heater for the gas to be supplied, a sensor that detects the temperature of the heated gas, an outlet for supplying the gas, and a mechanism for propelling the gas toward the supply outlet. A disposable supply duct can be coupled to the gas outlet for the insufflator in order to convey the heated gas into the patient and a return duct for the gas is connected to a distal area of the supply duct and to an inlet of the heater, wherein the gas supply duct and the gas return duct form a continuous recirculation circuit for heated gas.
