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 a driver for engaging 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 driver engages the valve so as move the valve to the open position. This allows fluid flow from the manifold and receiver to the downstream components of the system.
