Abstract

Abstract A power operated vacuum pump unit has a chamber connected to a vacuum pump maintained under negative pressure. There are four separate shut-off valves all connected to the chamber in each of which a fixed pressure is pre-set at amounts differing one from another, all of which are accessible from one side of a housing for the operating unit. There are a series of tubes having one end connected to each of the respective shut-off valves. Each tube is adapted at its other end to receive a glass or plastic suction applicator. Intermediate opposite ends of each tube is a transparent hollow spherical container having a beaded extension on each of two opposite sides for sealed engagement with a section of the respective tubing. In each spherical container is a mass of medical gauze serving as a filter for dirt laden liquids passing from the applicator end to the chamber.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 78 words
An applicator for the skin comprising a housing, a chamber in the housing in which a vacuum is generated, a plurality of shut-off valves on the housing and in communication with the chamber, means in communication with said valves establishing a different vacuum pressure for each of said valves, and a flexible tube having one end adapted for sealing engagement with a selected one of said shut-off valves and filter means in each tube intermediate opposite ends thereof.
Claim 2
Dependent Claim 78 words
An applicator for the skin comprising a housing, a chamber in the housing in which a vacuum is generated, a plurality of shut-off valves on the housing and in communication with the chamber, means in communication with said valves establishing a different vacuum pressure for each of said valves, and a flexible tube having one end adapted for sealing engagement with a selected one of said shut-off valves and filter means in each tube intermediate opposite ends thereof.
Claim 3
Dependent Claim 70 words
An applicator as in claim 1 wherein said filter means comprises a hollow bulbous member having oppositely directed extensions with beaded ends, said ends being adapted to sealably engage an adjacent end of a respective section of said tube, and a mass of relatively loosely compacted fibrous material releasably contained within said bulbous member whereby to serve as a filter for fluid material drawn through the tube into said chamber.
Claim 4
Dependent Claim 73 words
An applicator as in claim 1 wherein said means for establishing different vacuum pressures comprises a vacuum pump, a vacuum chamber in communication with said pump, a passage in communication between each valve and said chamber, and a restricted orifice in each passage, each said orifice having the capacity for passing air therethrough differing from every other passage whereby to make available at the respective valves a plurality of different fixed vacuum pressures.
Claim 5
Dependent Claim 148 words
A vacuum pressure applicator having a plurality of valves with a different fixed vacuum pressure available at each valve, said applicator comprising an electric motor, a vacuum pump, a manifold common to all said valves, a vacuum line connecting said pump and said manifold, a separate passageway between each valve and said manifold, and a constantly open restricted orifice in each passage in which flow is always in the same direction, the flow capacity of each orifice being different from every other orifice whereby to make available at the respective valves fixed vacuum pressures differing one from another while said motor and said pump operate at a constant rate, each said valve including a manual shut-off means acting independently of all the remaining shut-off means whereby any selected one of said valves is adapted to be operated at its individual flow capacity while the remaining valves remain inoperative.
Claim 6
Dependent Claim 148 words
A vacuum pressure applicator having a plurality of valves with a different fixed vacuum pressure available at each valve, said applicator comprising an electric motor, a vacuum pump, a manifold common to all said valves, a vacuum line connecting said pump and said manifold, a separate passageway between each valve and said manifold, and a constantly open restricted orifice in each passage in which flow is always in the same direction, the flow capacity of each orifice being different from every other orifice whereby to make available at the respective valves fixed vacuum pressures differing one from another while said motor and said pump operate at a constant rate, each said valve including a manual shut-off means acting independently of all the remaining shut-off means whereby any selected one of said valves is adapted to be operated at its individual flow capacity while the remaining valves remain inoperative.
Claim 7
Dependent Claim 138 words
A vacuum pressure applicator having a plurality of valves with a different fixed vacuum pressure available at each valve, said applicator comprising an electric motor, a vacuum pump, a manifold common to all said valves, a vacuum line connecting said pump to said manifold, a separate passageway between each valve and said manifold, and a constantly open restricted orifice in each passage in which flow is always in the same direction, the flow capacity of each orifice being different from every other orifice whereby to make available at the respective valves fixed vacuum pressures differing one from another while said motor and said pump operate at a constant rate, a separate container intermediate the vacuum pump and the manifold a vacuum line from said pump to said container and a vacuum line from said container to said manifold.
Claim 8
Dependent Claim 138 words
A vacuum pressure applicator having a plurality of valves with a different fixed vacuum pressure available at each valve, said applicator comprising an electric motor, a vacuum pump, a manifold common to all said valves, a vacuum line connecting said pump to said manifold, a separate passageway between each valve and said manifold, and a constantly open restricted orifice in each passage in which flow is always in the same direction, the flow capacity of each orifice being different from every other orifice whereby to make available at the respective valves fixed vacuum pressures differing one from another while said motor and said pump operate at a constant rate, a separate container intermediate the vacuum pump and the manifold a vacuum line from said pump to said container and a vacuum line from said container to said manifold.
Claim 9
Dependent Claim 129 words
A vacuum pressure applicator having a plurality of valves with a different fixed vacuum pressure available at each valve, sAid applicator comprising an electric motor, a vacuum pump, a manifold common to all said valves, a vacuum line connecting said pump and said manifold, a separate passageway between each valve and said manifold, and a constantly open restricted orifice in each passage in which flow is always in the same direction, the flow capacity of each orififice being different from every other orifice whereby to make available at the respective valves fixed vacuum pressures differing one from another while said motor and said pump operate at a constant rate, a second manifold intermediate the first identified manifold and the vacuum pump and a plurality of passages interconnecting said manifolds.
Claim 10
Dependent Claim 129 words
A vacuum pressure applicator having a plurality of valves with a different fixed vacuum pressure available at each valve, sAid applicator comprising an electric motor, a vacuum pump, a manifold common to all said valves, a vacuum line connecting said pump and said manifold, a separate passageway between each valve and said manifold, and a constantly open restricted orifice in each passage in which flow is always in the same direction, the flow capacity of each orififice being different from every other orifice whereby to make available at the respective valves fixed vacuum pressures differing one from another while said motor and said pump operate at a constant rate, a second manifold intermediate the first identified manifold and the vacuum pump and a plurality of passages interconnecting said manifolds.
Claim 11
Dependent Claim 35 words
A vacuum pressure applicator as in claim 5 wherein there is a second manifold connected to the vacuum line from said container to said first identified manifold and a plurality of passages between said manifolds.
