Abstract

A removable manifold for a medical/surgical waste collection system. The manifold is dimensioned to be mounted to a receiver integral with the system. The manifold includes at least one tube through which waste is drawn into a manifold cage. The tube extends through an inlet port into a void space internal to the manifold cage at an angle. The tube exits the manifold cage and centered along an axis that is off center to the longitudinal axis of the manifold cage where it engages a complementary valve internal to the receiver. The valve regulates flow between the receiver and the down line components of the waste collection system. The valve is normally closed. When the manifold is fitted to the receiver the tube engages the valve and rotation of the manifold moves the valve to the open position allowing fluid flow from the manifold and receiver to the downstream components of the system.

First claim

What is claimed is:

1. A manifold assembly for with a waste collection system comprising:
a cage comprising:
a base plate comprising a port extending through the base plate,
a cap plate spaced apart from and parallel to the base plate and comprising an opening extending through the cap plate, and
a rib extending between the base plate and the cap plate;

a tube extending from a first end adjacent the base plate port and passing through the cap plate opening, wherein the tube is fluidly connected with a conduit of the waste collection system; and
a filter assembly comprising:
a filter housing,
an inlet connectable with a suction line,
an outlet fluidly connected with a second end of the tube, and
a filter basket;

wherein the base plate port is offset from the cap plate opening such that a central axis of the tube extends between the cap plate and base plate at an angle that is not perpendicular to the cap plate and base plate.

2. The manifold assembly of claim 1 wherein the cage is inserted into a manifold receiver of the waste collection system.

3. The manifold assembly of claim 2 wherein the base plate is at least partially circular and the cap plate is at least partially circular.

4. The manifold assembly of claim 3 wherein a diameter of the cap plate is larger than a diameter of the base plate.

5. The manifold assembly of claim 4 wherein a center axis of the cap plate is offset from a center axis of the base plate.

6. The manifold assembly of claim 2 wherein the cap plate further comprises tabs extending from a periphery of the cap plate.

7. The manifold assembly of claim 1 wherein the first end of the tube engages a valve disk of the waste collection system.

8. The manifold assembly of claim 1 further comprising a finger grip extending from an outside surface of the cap plate.

9. The manifold assembly of claim 1 wherein the cage further comprises a second rib.

10. The manifold assembly of claim 1 wherein the filter assembly further comprises a second inlet.

11. The manifold assembly of claim 1 wherein a portion of the tube that extends between the cap plate and the filter assembly is flexible.

12. The manifold assembly of claim 11 wherein a portion of the tube that extends between the base plate and the cap plate is flexible.

13. The manifold assembly of claim 11 wherein a portion of the tube that extends between the base plate and the cap plate is more rigid than the tube portion that extends between the cap plate and the filter assembly.

14. The manifold assembly of claim 11 wherein a portion of the tube that extends between the base plate and the cap plate is relatively more rigid than the portion of the tube that extends between the cap plate and the filter assembly.

15. A manifold assembly for with a waste collection system comprising:
a cage inserted into a manifold receiver of the waste collection system, the cage comprising:
a base plate comprising a port extending through the base plate,
a cap plate spaced apart from the base plate and comprising an opening extending through the cap plate, and
a rib extending between the base plate and the cap plate;

a tube extending from a first end adjacent the base plate port and passing through the cap plate opening, wherein the tube is fluidly connected with a conduit of the waste collection system; and
a filter assembly comprising:
a filter housing,
an inlet connectable with a suction line,
an outlet fluidly connected with a second end of the tube, and
a filter basket

wherein the cap plate further comprises tabs extending from a periphery of the cap plate, and the cap plate tabs engage slots formed in an interior surface of the manifold receiver.

16. A manifold assembly for use with a waste collection system comprising:
a cage comprising:
an at least partially circular base plate comprising a port extending through the base plate,
an at least partially circular cap plate spaced apart from and parallel to the base plate and comprising an opening extending through the cap plate, and
a rib extending between the base plate and cap plate;

a tube extending from a first end adjacent the base plate port and passing through the cap plate opening, wherein the tube is fluidly connected with a conduit of the waste collection system; and
a filter assembly comprising:
a filter housing,
an inlet connectable with a suction line,
an outlet fluidly connected with a second end of the tube, and
a filter basket;

wherein the manifold assembly engages a valve disk of the waste collection system, and the cage rotates between a first position and a second position.

17. The manifold assembly of claim 16 wherein the cage is inserted into a manifold receiver of the waste collection system.

18. The manifold assembly of claim 17 wherein the filter assembly is positioned outside the manifold receiver.
