EXHALING VALVE

摘要

An exhaling valve (1) comprises a valve body. The valve body comprises: a first valve port (11), used for exhaling gas; a second valve port (12), used for being connected to a PEEP valve, wherein an exhaling channel (13) is disposed between the first valve port (11) and the second valve port (12); and a traffic collecting module, disposed in the exhaling channel (13). Part of exhaled gas that enters the exhaling channel (13) through the first valve port (11) passes through the traffic collecting module, then generates a pressure difference and then enters a collecting port; and the other part enters the PEEP value through the second valve port (12). The exhaling valve (1) can improve the precision of traffic monitoring and the control stability of the PEEP valve, can be rapidly fitted to the collecting port, can be wholly disassembled for being disinfected, and accordingly, the exhaling valve is safe and reliable.
