Abstract:

A suction canister assembly includes an outer collection bottle having a bottle mouth, an inner canister nested therein having a canister mouth and having a valve device at its bottom end, a dual closure lid closing off both the bottle mouth and the canister mouth and having an inlet port and an outlet port in communication with the canister, and a fluid porous specimen receptacle suspended from the lid and surrounding the inlet port. With the valve device open, a catheter assembly is exteriorly connected to the inlet port while negative pressure is applied to the outlet port. The catheter assembly is used for vacuum aspiration of a patient with solid material being retained within the receptacle and liquid material passes into the canister, through the valve device, and into the collection bottle. After completion of the procedure, the lid and inner canister combination may be removed from the collection bottle, the valve device closed and the solid material collected within the receptacle is safe for transport.
