Abstract

A medical apparatus and method for draining bodily fluid from a container, such as a suction canister.

Claims

1. A medical apparatus for draining bodily fluid held in a container, said apparatus comprising:

a support area that is adapted to removably supporting the container;

a vacuum generator in communication with said support area, said generator selectively generating a vacuum in said support area such that the vacuum holds the container in said support area;

a tool that is actuable to alter the container such that the fluid held in the container drains from the container; and

a cam assembly, wherein said cam assembly has a first position wherein said vacuum generator is inactive, and a second position wherein said vacuum generator creates the vacuum.

2. The medical apparatus of claim 1 wherein said cam assembly is movable into said first and second positions through movement of a handle.

3. The medical apparatus of claim 1 and further including an actuation handle operatively connected to said vacuum generator and said tool, said handle having a first position that actuates said vacuum generator and a second position that actuates said tool.

4. The medical apparatus of claim 1 wherein said tool is actuable in that said tool is movable upwardly from resting position to a position in which it is adapted to alter the container.

5. A medical apparatus for draining bodily fluid held in a container, said apparatus comprising:

a support area that is adapted to removably supporting the container;

a vacuum generator in communication with said support area, said generator selectively generating a vacuum in said support area such that the vacuum holds the container in said support area;

a tool that is actuable to alter the container such that the fluid held in the container drains from the container; and

a cam assembly operatively connected to said vacuum generator, and wherein said vacuum generator selectively generates the vacuum when said cam assembly is in a first position.

6. The medical apparatus of claim 5 wherein said tool is actuable when said cam assembly is in a second position.

7. The medical apparatus of claim 6 wherein said cam assembly must pass through said first position before entering said second position.

8. A drainage apparatus for draining bodily fluid held in a container, said apparatus comprising:

a support area that is adapted to removably support a container;

a vacuum generator in communication with said support area;

an opener adapted to open the drain of a container; and

a cam assembly operatively connected to said generator for selectively actuating said generator to create a vacuum in said support area and operatively connected to said opener for moving said opener a distance that would allow the opener to engage the container in said support area to open the drain allowing bodily fluid to flow out of the container.

9. The apparatus of claim 8 wherein said cam assembly includes a cam shaft, a first cam mounted on said shaft and connected to said generator and a second cam mounted on said shaft and connected to said opener.

10. The apparatus of claim 9 wherein rotation of said shaft a predetermined amount creates the vacuum in said support area and continued rotation of said shaft a further predetermined amount moves said opener.

11. The apparatus of claim 10 and further including a manual handle connected to said shaft.

12. The apparatus of claim 8 wherein said generator includes a venturi valve.

13. The apparatus of claim 8 wherein said opener includes a passageway and wherein when said opener is moved into engagement with the container, fluid is able to drain from the container through said passageway.

14. An apparatus for draining bodily fluids from two differing types of containers holding bodily fluid, said apparatus comprising:

a first support area for removably supporting a first type of container;

a second support area for removably supporting a second type of container;

a first inlet adapted for communication with the first type of container, said first inlet accepting bodily fluid drained from the first type of container;

a second inlet adapted for communication with the second type of container, said second inlet accepting bodily fluid drained from the second type of container; and

a vacuum generator for creating a vacuum at said first inlet and said second inlet.

15. The apparatus of claim 14 wherein said generator includes a first venturi valve for creating a vacuum at said first inlet and a second venturi valve for creating a vacuum at said second inlet.

16. The apparatus of claim 15 wherein said generator includes a Y-type manifold in communication with said first and second venturi valves.

17. The apparatus of claim 14 wherein said generator creates a vacuum at one of said first or second support areas to hold the respective container in said one of said first and second support areas.

18. The apparatus of claim 14 and further including an actuation handle in communication with said vacuum generator.

19. The apparatus of claim 14 and further including means for backflushing at least one of said first and second venturi valves.

20. The apparatus of claim 14 and further including a sprayer in communication with a source of cleaning fluid.

21. A method for draining bodily fluid from a container, said method comprising the steps:

positioning a container having bodily fluids therein on a support area of a drainage device;

moving a cam assembly in the drainage device to a first position wherein a vacuum is created in the support area to hold the container in place; and

moving the cam assembly to a second position wherein a tool of the drainage device alters the container to release the bodily fluid from the container.

22. A method for draining bodily fluids from a container, said method comprising the steps:

positioning a container having bodily fluids therein on a support area of a drainage device;

creating a vacuum in the support area to hold the container in place; and

operating the drainage device with a rotatable handle to alter the container to drain the bodily fluid from the container.

23. The method of claim 22 wherein in the creating step, the vacuum is created by a fluid moving through a venturi.

24. The method of claim 23 wherein the fluid includes water.

25. The method of claim 22 wherein in the operating step, a tool is moved upwardly to alter the container.

26. The method of claim 22 wherein in the operating step, the container is permanently altered by the drainage device opening a drain port in the container.

27. The method of claim 26 wherein the drain port is in a bottom surface of the container.

28. The method of claim 22 wherein in the positioning step, the support area is a recess.

29. The method of claim 22 wherein rotation of the handle actuates the creation of the vacuum.

30. The method of claim 22 wherein the container is a suction canister.
