Laparoscopic irrigation bottle pump

摘要

A laparoscopic irrigation system and bottle pump for controlling a source of gas pressure driving a source of irrigation solution that includes a monitor for monitoring the source of gas pressure and indicating when the gas pressure falls below a predetermined value. Also, the liquid level of the source of irrigation solution is monitored via infrared radiation and when the level falls to a predetermined value it is detected, a visual and an audible signal is actuated and an alternative source of irrigation solution is selected. Further the level of gas pressure driving the source of irrigation solution is controllable with an electronic circuit containing a stepping motor mechanically connected to a pressure regulator.
