Aseptic suction system for body fluids and valve therefor

Claim 2

A body fluid receiving system for use in locations where bodies are worked upon, said system including a fluid receiver with means for connecting the interior of the receiver to the body being worked upon and also to a vacuum system, wherein the improvement comprises a transparent housing in the vacuum line mounted so air passes through said housing from one end to the other drawn by the vacuum system, and entrapment means in said housing to entrap fluid particles in a manner visible from a distance to denote to an observer that some body fluid has passed beyond the receiver, said entrapment means including a deflector plate spaced inwardly from the inlet end of the housing and shaped to cause the air passing through to assume a vortex.

Claim 3

The system of claim 1, including a floating valve disc spun rapidly by the air vortex.

Claim 4

The system of claim 1 including a circumferential series of blades on said deflector plate sloping in a manner to cause said vortex.

Claim 5

The system of claim 3, wherein said valve disc spins bodily in a manner approximating a precessional rotational movement.

Claim 6

A body fluid receiving system for use in locations where bodies are worked upon, said system including a fluid receiver with means for connecting the interior of the receiver to the body being worked upon and also to a vacuum system, wherein the improvement comprises a transparent housing in the vacuum line mounted so air passes through said housing from one end to the other drawn by the vacuum system, and entrapment means in said housing to entrap fluid particles in a manner visible from a distance to denote to an observer that some body fluid has passed beyond the receiver, said entrapment means including a spinning valve disc capable of throwing off fluid particles by centrifugal force against the inner wall of said housing.

Claim 7

A body fluid receiving system for use in locations where bodies are worked upon, said system including a fluid receiver with means for connecting the interior of the receiver to the body being worked upon and also to a vacuum system, wherein the improvement comprises a transparent housing in the vacuum line mounted so air passes through said housing from one end to the other drawn by the vacuum system, and entrapment means in said housing to entrap fluid particles in a manner visible from a distance to denote to an observer that some body fluid has passed beyond the receiver, said entrapment means including a spinning valve disc capable of throwing off fluid particles by centrifugal force against the inner wall of said housing.

Claim 8

The system of claim 5, wherein said valve disc has a circumferential groove therein, and a soft substance is inserted in said groove to absorb vibration and reduce the noise of the spinning valve disc.

Claim 9

The system of claim 5, including a pinch of a substance in flour form capable of acting as a dry lubricant to reduce the noise of the spinning valve disc.

Claim 10

A body fluid receiving system for use in locations where bodies are worked upon, said system including a fluid receiver with means for connecting the interior of the receiver to the body being worked upon and also to a vacuum system, wherein the improvement comprises a transparent housing in the vacuum line, an inlet fitting at one end of said housing, and an outlet fitting at the other end of said housing, both said fittings communicating with the interior of said housing and connected in the vacuum line to make the housing a component part thereof, and means in said housing to entrap fluid particles in a manner visible from a distance to denote to an observer that some body fluid has passed beyond the receiver, said entrapment means including means to cause air passing through said housing to assume a vortex, and a valve disc spun rapidly to the vortex of air.

Claim 11

A body fluid receiving system for use in locations where bodies are worked upon, said system including a fluid receiver with means for connecting the interior of the receiver to the body being worked upon and also to a vacuum system, wherein the improvement comprises a transparent housing in the vacuum line, an inlet fitting at one end of said housing, and an outlet fitting at the other end of said housing, both said fittings communicating with the interior of said housing and connected in the vacuum line to make the housing a component part thereof, and means in said housing to entrap fluid particles in a manner visible from a distance to denote to an observer that some body fluid has passed beyond the receiver, said entrapment means including means to cause air passing through said housing to assume a vortex, and a valve disc spun rapidly to the vortex of air.

Claim 12

The system of claim 8 including a valve seat adjacent the outlet from said housing against which said valve disc will seat when drawn thereagainst by suction after some fluid has entered the housing.

Claim 13

The system of claim 9 including guide means between said valve seat and the outlet from said housing to guide the valve disc into and maintain it in position to spin bodily in a manner approximating a precessional rotational movement.

Claim 14

The system of claim 10, including a cylinder around the outlet of the housing and extending inwardly from the end of the housing, said valve seat being at the inner end of said cylinder, a smooth topped table on The means causing incoming air to assume a vortex, said guide means comprising a flange on said cylinder having a smooth chamfered circumference, said valve having a circumferential groove therein defined by an inner curvate top edge and a curvate portion defining said groove, whereby during its spinning motion the inside curvate edge at the groove in said valve disc tracks on the chamfer of said guide means, and the curvate groove portion tracks on the inside wall of said housing and said table, all smooth surfaces of contact.
