Abstract

A system for collecting and disposing of liquid medical waste includes a fluid collection cart and a draining and cleaning station. The fluid collection cart includes a pair of containers, each of which includes a draining port and a cap. Liquid level detectors also communicate with each container. The cart also includes a regulator so a low vacuum level may be pulled on one of the containers while a full vacuum level is pulled on the other container. Fluids are collected in the containers via suction tubes connected to the patient ports. The flushing and drain ports of the containers are connected to corresponding flushing and drain connectors on the station when the containers are full so that they may be drained and flushed. The cart liquid level detectors communicate with the station microprocessor so that the draining and flushing cycles may be properly sequenced.

Claims (19)

1. A system for collecting and disposing of liquid waste comprising:

a) a fluid collection cart including:

i) a body supported by a plurality of wheels;

ii) a container supported by said body and featuring vacuum, patient, flushing and drain ports, where liquid waste is collected within the container through the patient port when the vacuum port is connected to a vacuum source and the flushing and drain ports are closed;

b) a station including;

i) a cabinet having a sink with an open top and drain and flushing connectors, said sink and said drain connector in communication with a drain and said flushing connector adapted to communicate with a water source;

ii) a canister that is separate and distinct from the container of the cart and that features a removable lid;

iii) means for securing the canister filled with liquid waste within the sink;

iv) means for draining the liquid waste from the canister into the sink and drain;

v) means for flushing residue out of the canister, said means for flushing adapted to communicate with the water source; whereby the drain and flushing connectors of the station may be connected to the drain and flushing ports of the cart container so that liquid waste collected within the container may be drained through the drain of the station and flushed with water from the water source.

2. The system for collecting and disposing of liquid waste of claim 1 further comprising a liquid level sensor in communication with the container of said fluid collection cart and microprocessor positioned within the cabinet of said station, said microprocessor selectively communicating with said liquid level sensor so that the microprocessor may sequence the draining and flushing of the cart container.

3. The system of claim 2 wherein said liquid level detector is a capacitance sensor.

4. The system of claim 2 further comprising a flushing connector in communication with said flushing port, a drain connector in communication with said drain port and an electrical connector in communication with said liquid level detector, said flushing, drain and electrical connectors mounted upon a side panel of said cart.

5. The system of claim 1 further comprising a vacuum regulator positioned on the body of said cart and in communication with said vacuum port of said container, said vacuum regulator adapted to selectively communicate with the vacuum source so that a vacuum level pulled on the container may be regulated.

6. The system of claim 5 :

wherein said container is a first container, and

further comprising a second container supported by said body and having a cap that includes vacuum and patient ports, said patient port adapted to selectively communicate with a suction line and said vacuum port adapted to selectively communicate with the vacuum source so that an unregulated, full vacuum level may be pulled on the second container while a regulated vacuum level is simultaneously pulled on the first container.

7. The system of claim 6 wherein said cap includes an inner portion and an outer portion, said inner cap portion having said patient port and said vacuum port formed therein and said outer cap portion having said flushing port and a bore formed therein with said inner cap portion removably received within the bore of said outer cap portion.

8. The system of claim 7 further comprising a cleaning nozzle positioned within said container and in communication with said flushing port.
