ABSTRACT:
An apparatus for surgical aspiration and monitoring of the aspirated fluids includes a sealable aspiration bottle supported by an electronic weighing scale on a base stand. The bottle includes tubing connectors joined to a negative gauge pressure source and to an aspirating surgical instrument. A pair of electrodes extend into the bottle and are connected to an electronic circuit which measures the impedance of the fluid/tissue aspirate in the bottle. A microprocessor receives the impedance and net weight data of the aspirate, determines the relative amounts and net weights of fluid and tissue in the aspirate, and displays this information on a visual display.
