Abstract
A medical insufflation device having a control device with feedback sensors for regulating the flow of a gas into an inflatable body cavity. The device includes a conduit for channeling gas from a gas supply into an insufflation instrument, sensors for measuring gas pressure and gas flow in the conduit, and a control device responsive to the sensors for automatically regulating the pressure and flow of the gas into the body cavity from the conduit. The control device has an automatic processing unit for receiving the measured gas pressure and flow values from the sensors and for using those values to control an actuator in the conduit and which is operatively adjustable for regulating the flow of gas into the body cavity. During insufflation, when the pressure sensor detects a drop in pressure or that the measured pressure is no longer increasing, the control device automatically operates the actuator to reduce the pressure in the conduit until the gas flow falls to a minimum value such, for example, as zero while the body cavity remains open.
