Removable inlet manifold for a medical waste collection system
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.
1. A manifold assembly for use with a waste collection system comprising:
a manifold that is inserted into a manifold receiver of the waste collection system, the manifold comprising:
a circular base plate comprising an outlet port extending through the base plate,
a circular cap plate spaced apart from the base plate and comprising an inlet opening extending through the cap plate, and
a tube connecting the base plate port with the cap plate opening such that waste collected by the waste collection system flows into the manifold through the cap plate opening, through the tube, and out of the manifold through the base plate port when the manifold is in use; and
a filter assembly comprising:
a filter housing,
a filter basket, and
an outlet fluidly connected with the manifold tube;
wherein the outlet port of the manifold engages a valve of the waste collection system such that the valve is open when the manifold is fully inserted into the manifold receiver and the valve is closed when the manifold is removed from the manifold receiver.
2. The manifold assembly of claim 1 wherein inserting the manifold opens the valve by actuating a valve disk of the valve.
3. The manifold assembly of claim 2 wherein the manifold outlet port engages a boss extend from the valve disk.
4. The manifold assembly of claim 2 wherein rotating the manifold during insertion rotates the valve disk.
5. The manifold assembly of claim 1 wherein the manifold further comprises a tab.
6. The manifold assembly of claim 5 wherein the tab engages a receiver slot formed in the manifold receiver.
7. The manifold assembly of claim 6 wherein an initial engagement between the tab and the receiver slot aligns the manifold base plate with a valve disk of the valve.
8. The manifold assembly of claim 6 wherein the manifold is rotated to fully engage the tab with the receiver slot.
9. The manifold assembly of claim 8 wherein the rotation of the manifold rotates the valve disk.
10. A manifold assembly for use with a waste collection system comprising:
a manifold that is inserted into a manifold receiver of the waste collection system, the manifold comprising:
a circular base plate comprising an outlet port extending through the base plate,
a circular cap plate spaced apart from the base plate and comprising an inlet opening extending through the cap plate,
a tube connecting the base plate port with the cap plate opening such that waste collected by the waste collection system flows into the manifold through the cap plate opening, through the tube, and out of the manifold through the base plate port when the manifold is in use, and
a rib connecting the base plate with the cap plate; and
a filter assembly comprising:
a filter housing,
a filter basket, and
an outlet fluidly connected with the manifold tube;
wherein the base plate, the cap plate, and the rib of the manifold form a cage having closed ends and an open side; and
wherein the outlet port of the manifold engages a valve of the waste collection system such that the valve is open when the manifold is fully inserted into the manifold receiver and the valve is closed when the manifold is removed from the manifold receiver.

12. The manifold assembly of claim 11 wherein the tube is not accessible when the manifold has been inserted into the manifold receiver.
13. The manifold assembly of claim 10 wherein the manifold further comprises a second rib.
14. The manifold assembly of claim 13 wherein the base plate comprises an inside surface and the cap plate comprises an inside surface.
15. The manifold assembly of claim 14 wherein the base plate inside surface is parallel to the cap plate inside surface and the first rib is parallel to the second rib.
16. A manifold assembly for use with a waste collection system comprising:
a manifold that is inserted into a manifold receiver of the waste collection system, the manifold comprising:
a circular base plate comprising an outlet port extending through the base plate,
a circular cap plate spaced apart from the base plate and comprising an inlet opening extending through the cap plate,
a tube connecting the base plate port with the cap plate opening,
a first rib connecting the base plate with the cap plate, and
a second rib connecting the base plate with the cap plate; and
