Abstract
A collection reservoir 54 includes a rigid-walled cassette adapted for connection to aspiration tubing 50. The cassette also includes a pair of electrodes 36 positioned so that the electrodes are electrically connectable to a flow meter 34. In operation, the electrodes are exposed to the fluid and tissue being aspirated from the surgical site so that the flow meter indicates a flow rate of the fluid and tissue from the surgical site.
Claims2
A collection reservoir for use in a surgical pump system comprising:
- a rigid-walled cassette adapted for connection to an aspiration tube and for receiving fluid and tissue aspirated from a surgical site;
- and
- a pair of electrodes molded into the cassette and positioned so that the electrodes are electrically connectable to a flow meter wherein the electrodes, in operation, are exposed to the fluid and tissue such that the flow meter indicates a flow rate of the fluid and tissue from the surgical site without the electrodes interfering with the flow of fluid and tissue through the cassette.
