Abstract

A liquid waste disposal and canister flushing system and method for a medical canister including a lid with at least first and second ports features a cabinet with an opening and a sink with a drain positioned therein. A removable lid covers the cabinet opening. A canister holder in the form of a ring or bucket is positioned within the chamber defined between the sink and cabinet opening. The canister holder is supported by a rod that is rotatably positioned in the cabinet. The rod is also connected to an electric motor or lever so that the canister holder, and therefore the canister positioned therein, may be rotated between an initial position and a drainage position. The canister is secured within the canister holder and tubing, which is in communication with a source of pressurized and diluted cleaning solution, is connected to the first canister port. The canister is rotated into the drainage position and the pressurized and diluted cleaning solution source is activated to flush the canister contents out of the second lid port and into the sink and drain. The first canister port may optionally feature a nozzle oriented at an angle so that a swirling action is induced upon the pressurized liquid entering the canister to assist in the flushing of residue from the canister.

Claims

1. A liquid waste disposal and canister flushing system for a canister having a base and a lid with first and second ports comprising:

a) a cabinet having an opening;

b) a sink disposed within said cabinet so that a chamber is defined between said sink and the opening in the cabinet;

c) a drain in communication with said sink;

d) a canister holder positioned within said chamber, said canister holder adapted to removably receive the canister;

e) a device for rotating said canister holder so that a canister positioned therein is rotated between an initial position and a drainage position; and

f) tubing in communication with a source of pressurized liquid, said tubing adapted to engage the first port of the canister lid so that the pressurized liquid can be introduced into the canister to flush residue out through the second port and into the sink and drain when the canister is in the drainage position.

2. The system of claim 1 further comprising a removable lid for covering the cabinet opening.

3. The system of claim 1 wherein said source of pressurized liquid includes a source of pressurized cleaning solution.

4. The system of claim 3 wherein the cleaning solution includes bleach.

5. The system of claim 4 wherein the cleaning solution includes a defoamer.

6. The system of claim 1 wherein the canister holder includes a bucket sized to removably receive the canister.

7. The system of claim 1 wherein the canister holder includes a ring sized to removably receive the canister.

8. The system of claim 1 wherein the device for rotating said canister holder includes a rod connected to the canister holder, said rod rotatably mounted within said cabinet, and an apparatus for rotating said rod.

9. The system of claim 8 wherein the apparatus for rotating said rod includes an electric motor.

10. The system of claim 8 wherein the apparatus for rotating said rod includes a lever.

11. The system of claim 1 further comprising a nozzle adapted to be placed in communication with the first port of the canister lid, said nozzle oriented at an angle so that a swirling action is induced upon the pressurized liquid entering the canister to assist in the flushing of residue from the canister.

12. A liquid waste disposal and canister flushing system comprising:

a) a canister including a lid with first and second ports;

b) a cabinet;

c) a sink positioned within said cabinet, said sink in communication with a drain;

d) a canister holder removably securing the canister above said sink;

e) a device for rotating the canister holder, and therefore said canister, between initial and drainage positions; and

f) tubing in communication between the first port of the canister lid and a source of pressurized liquid, said source of pressurized liquid activated when said canister is in the drainage position so that the canister is flushed with its contents passing through the second port of the canister lid, into the sink and down the drain.

13. The system of claim 12 wherein the pressurized liquid is a cleaning solution.

14. The system of claim 12 wherein the canister holder includes a bucket sized to removably receive the canister.

15. The system of claim 12 wherein the canister holder includes a ring sized to removably receive the canister.

16. The system of claim 12 wherein the device for rotating said canister holder includes a rod connected to the canister holder, said rod rotatably mounted within said cabinet, and an apparatus for rotating said rod.

17. The system of claim 16 wherein the apparatus for rotating said rod includes an electric motor.

18. The system of claim 16 wherein the apparatus for rotating said rod includes a lever.

19. The system of claim 12 further comprising a nozzle in communication with the first port of the canister lid, said nozzle oriented at an angle so that a swirling action is induced upon pressurized liquid entering the canister to assist in the flushing of residue from the canister.

20. A method of disposing of liquid waste from a canister having a lid with first and second ports comprising the steps of:

a) providing a sink and a drain;

b) providing a source of pressurized liquid;

c) connecting the first port of the canister lid to the source of pressurized liquid;

d) rotating the canister above the sink into a drainage position;

e) flushing the canister with the source of pressurized liquid; and

f) draining the liquid waste in the canister out of the second port and into the sink and drain.
