Fast response vacuum aspiration collection system
First Claim
1. A fast response vacuum aspiration collection system, comprising an aspiration surgical instrument a pair of sealed collection containers, one container having a significantly smaller volume than the other, separate vacuum connected to each of said containers individually, an exchange line connected between said containers for open flow communication therebetween, a first valve interposed on said exchange line, an aspiration line connected to said aspirating surgical instrument at one end and connected to said exchange line at the other end, a second valve interposed on said aspirating line, said aspirating line joining said exchange line at a point located between said first valve and said one container.

Abstract
A fast response vacuum aspiration collection system includes a pair of sealed collection containers, one container having a significantly smaller volume. The larger container is connected to a fixed vacuum source, the smaller container is connected to a controlled, variable vacuum source, and the containers are connected together by an exchange line passing through a normally closed first pinch valve. A surgical probe line is connected to the exchange line, and extends through a normally closed second pinch valve to an aspirating surgical instrument. The controlled vacuum applied to the smaller container is conducted through the exchange line and the surgical line to the surgical instrument, with the small volume of the small container quickly assuming the vacuum level applied to that container. When the small container is filled, the second pinch valve is closed and the first pinch valve is opened, allowing the vacuum applied to the larger container quickly to withdraw fluid from the smaller container to the larger container.
