Abstract: 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.

Abstract: An irrigation set for use with a laparoscopic and/or hysteroscopic irrigation pump includes a bottle cap having an open mouth, closed-end cup shape threaded on the inside surface and defining a region just inside the closed end provided with an undercut and an opening defined in the closed end. A disk assembly is composed of a disk received in the region and retained therein by the undercut. The side of said disk inside the cap defines a depending skirt. The disk defines a first opening aligned with the depending skirt, a check valve cartridge and draw tube secured to the depending skirt. A first tubular projection on the disk is aligned with the first opening and projects through the opening in the closed end. A second tubular projection on the disk is aligned with the second opening and projects through the tubular opening in the closed end. A gas tubing is secured at one end to the second tubular projection, and a gas fitting is secured to the other end of the gas tubing.
