Abstract

A system for collecting and disposing of body fluids collected during surgery comprises a canister and a servicing unit for removing the body fluids from the canister and cleaning the canister for re-use. The canister is a vessel having sidewalls, a bottom and a lid. The lid has a first inlet port for the inflow of body fluids into the canister during surgery and a vacuum port for application of vacuum to the canister to induce the inflow of body fluids into the canister. The lid has a second inlet port for the inflow of cleaning fluid into the canister and a spray head in fluid communication with the second inlet port for spraying the cleaning fluid within the canister. The lid also has an outlet port with a suction tube extending into the canister for the outflow of body fluids and cleaning fluid from the canister. Caps are provided for closing those ports when the canister is being used to collect body fluids during surgery. The servicing unit has a first fluid conduit means to conduct fluid from the canister to a drain, and a second fluid conduit means to conduct cleaning fluid from a source of cleaning fluid to the second inlet port of the canister. There are connectors for connecting the first fluid conduit means to the outlet port of the canister and for connecting the second fluid conduit means to the second inlet port of the canister. Means are provided to control the flow of fluids through the fluid conduit means.

6. The system in accordance with claim 5 further comprising a floatball cage for housing said floatball, said floatball cage comprising a needle valve guide for slidably retaining said needle valve.

7. The system in accordance with claim 1 wherein said spraying means is a rotatable sprayhead.

8. The system in accordance with claim 1 wherein said second fluid conduit means comprises a pump capable of providing pulses of fluid pressure.

9. The system in accordance with claim 1 wherein said spraying means is a sprayhead forming an annulus around said suction tube.

10. A system for collecting and disposing of body fluids comprising:

a canister for receiving said body fluids, comprising;

a body having side walls and a bottom and adapted to receive a lid;

a lid for covering said body;

a first inlet port in said lid for inflow of body fluids into said canister;

a second inlet port in said lid for inflow of cleaning fluid into said canister;

spraying means in fluid communication with said second inlet port for spraying said cleaning fluid within said canister;

means for closing said second inlet port during said inflow of body fluids into said canister;

an outlet port in said lid for outflow of body fluids and said cleaning fluid from said canister;

a conduit in fluid communication with said outlet port extending into said canister; and

means for closing said outlet port during said inflow of body fluids into said canister;

(b) a servicing unit for removing said body fluids from said canister and cleaning said canister, comprising;
