ABSTRACT:
Gases from a pressure relief valve in the patient circle are coupled to a first end of an elongated rigid cylinder, the other end of which is coupled to a vacuum exhaust pump. Coaxially disposed within the cylinder is an elongated tube which deposits gases from the valve to within a predetermined distance of the vacuum withdrawal port of the cylinder. The cylinder defines openings to ambient air at the first side, and baffling material is provided at the vacuum withdrawal end to facilitate intermixing of gas and air and prevent gas splashing.
