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. An annular gasket is secured to the side of the disk, about the peripheral portion thereof, to seal the mouth of a bottle. The first tubular projection is connected by tubing with an irrigation probe. Finally, a cap assembly is provided for an irrigation.
