An improved apparatus and method for insufflation with gas.

摘要

An improved gas insufflation system for delivering high pressure insufflation gas to a patient. The insufflation system comprises a gas line for delivering insufflation gas to a patient connected to a gas supply system which is under control of an electronic control system. The electronic control circuit is responsive to the gas pressure and gas flow rate in the line for controlling the gas supply system to deliver the gas in the line at a predetermined pressure and flow rate. The electronic control circuit is also connected to a patient monitoring system for reducing the gas pressure and flow rate when a patient physiological parameter reaches a predetermined level. A display panel is also connected to the electronic control circuit for displaying gas pressure, flow rate, and the physiological parameter. The gas supply system includes first and second gas reservoirs connected to an electronically controlled valve which selectively connects the gas reservoirs to the gas line. Heating elements and thermal insulation are also provided disposed about the gas line to maintain the temperature of the insufflation gas at a prescribed level.
