Abstract
An improved float safety mechanism (also herein 'float control valve') for a gas pressurized bottle irrigation system is disclosed herein and a procedure involving the use and application thereof is also herein disclosed. In the improved safety float system of this invention, a pressurizable reservoir containing a laproscopic irrigation fluid is provided with a unique and highly reliable float or anti-siphon valve for real-time sensing of the fluid level within the reservoir and automatically terminating the withdrawal of the fluid therefrom when the level of fluid drops below a prescribed limit. The design of the anti-siphon valve used in this system is unique to the demanding pressurized environment within which the valve must function. The float safety mechanism of this invention prevents the high pressure CO.sub.2 gas contained with the pressurizable reservoir from escaping (after depletion of the fluid) and entering the abdominal cavity during laparoscopy, causing possible serious or fatal injury.
