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.

Abstract:

A waste collection and disposal system for use in health care facilities is provided. The system includes a mobile waste collection unit for moving between use areas in the health care facility to collect waste material generated during medical procedures including body fluids, body tissues, saline, etc. The waste collection unit includes stacked upper and lower waste containers for receiving the waste material. During use, the upper waste container can be emptied into the lower waste container for temporary storage. In addition, different vacuum levels can be provided in the waste containers during complex procedures. Once a user desires to empty the waste collection unit, the waste collection unit is wheeled to a docking station. At the docking station, the waste material is off-loaded to a waste drain and the waste collection unit is cleaned and rinsed for further use.

Abstract:

A method of collecting medical waste in a waste collection unit using a disposable manifold and filter assembly. The disposable manifold and filter assembly includes a manifold housing with a plurality of inlets, a neck extending from the manifold housing to define an outlet, and a filter basket disposed in the manifold housing. The method includes inserting the neck into the waste collection unit to direct the medical waste passing through the disposable manifold and filter assembly into the waste collection unit. Tubes are connected to the inlets of the manifold housing to provide a path for the medical waste to travel from a target site, e. g. , a patient, to the manifold housing. A vacuum is drawn in the waste collection unit to pull the medical waste through the tubes and into the disposable manifold and filter assembly where the medical waste is processed/filtered in a plurality of stages.

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 includes at least one fitting through which waste is drawn into the manifold. The fitting opens through an inlet port into a void space internal to the manifold. A backflow prevention valve is disposed in the manifold void space. The backflow prevention valve includes a static hub to which 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.

Abstract:

A manifold and filter assembly for use with a waste collection unit is provided. The manifold and filter assembly directs and filters medical waste flowing into the waste collection unit. The manifold and filter assembly comprises a manifold body defining a chamber and an outlet for directing the medical waste into the waste collection unit. A manifold cap is fitted to the manifold body to close the chamber. The manifold cap defines a plurality of inlets for receiving the medical waste. A filter basket having a bottom and a peripheral wall defining a plurality of openings is snap-locked to the manifold body. The filter basket is positioned such that a fluid bypass is formed between the filter basket and the manifold body and between the filter basket and the manifold cap. The fluid bypass is in fluid communication with the outlet whereby the medical waste can flow over the peripheral wall to the outlet through the fluid bypass.
