Abstract: A medical gas insufflation device comprising at least a gas outlet circuit, a connector for connecting a pressurized vessel in which the gas is packaged, an expander placed between the connector and the gas outlet circuit, a high-pressure sensor placed between the connector and the expander, a flow meter placed at the outlet from the expander, and a microprocessor connected at least to the sensor to receive signals representative of the pressure observed at the connector and to the flow meter to receive signals representative of the flow rate at the outlet from the expander, wherein the microprocessor includes evaluation means for evaluating the remaining volume of gas after expansion as a function of the signals received from the sensor and the flow meter during a gas expansion operation.

Abstract: A control device includes an arm (12) for mounting an instrument and at least one motion sensor (16) to be placed on the operator (2) of the control device and equipped to sense the movement of the operator according to the degree of freedom of the mounting arm (12), the device including an element (20) for processing signals emitted by the motion sensor (16), the element (20) being equipped to process the signals emitted by the motion sensor (16) and to send the corresponding control signals to the mounting shaft (12) so that the movement sensed by the motion sensor (16) controls the corresponding movements of the mounting arm (12). The device also includes an element for starting and stopping the detection of the motion of the operator by the sensor (16).
