Evacuation arrangement for gases exhaled by a patient

Abstract

Abstract 1. Evacuation arrangement for gases exhaled by a patient through a respirator (1) having a gas line (6) which connects the gas outlet orifice (5) of the respirator to a receiving tank (9) for the evacuated gas, the gas line being connectable through an orifice (14) to the atmosphere, characterized in that a valve (11) is arranged in the gas line (6) between the gas outlet orifice (5) and the orifice (14) for connecting the gas line (6) to the atmosphere, and interrupts the connection from the gas outlet orifice (5) to the receiving tank (9) when the pressure in the gas line (6) between valve (11) and gas outlet orifice (5) falls below a predeterminable value.
