ABSTRACT:
The disclosure herein sets forth a pleural drainage/autotransfusion unit in combination with a cardiotomy reservoir having a vacuum regulating chamber in connected relationship to the pleural drainage/autotransfusion unit. The vacuum regulating chamber is formed of a portion of said cardiotomy reservoir unit and extends along the axial direction of the reservoir of the autotransfusion unit and can be connected to a source of vacuum. A water seal is interposed between the vacuum regulating chamber and the interior of the reservoir in order to provide for water sealed negative pressure within the reservoir. The function of the cardiotomy reservoir and the pleural drainage/autotransfusion unit can be changed by means of connections that have spring loaded tangs that engage a flange of a barbed inlet port. The connection is sealed by means of a resilient plastic material engaging the barbed inlet ports and can be readily removed therefrom and sealed without the requirement of sealing a tube which has been shrunken over the barbs of the inlet port.
