Problems solved by technology

[0003] 1. The flow acquisition module is independent of the exhalation valve assembly. When connecting the patient pipeline, the connection operation of the flow acquisition module needs to be performed separately, which increases the workload of the client and increases the probability of errors
At the same time, since the flow collection module is in contact with the patient's exhaled gas, if it is not sterilized during use, it will increase the risk of cross-infection of the patient
[0004] 2. The exhalation valve assembly of the integrated flow acquisition module, when controlling the PEEP valve, the airflow is easily affected by the PEEP valve, resulting in large airflow fluctuations, affecting the measurement accuracy of the flow acquisition module, and thus affecting the control stability of the PEEP valve

Abstract

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.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to an exhalation valve. Background technique [0002] The exhalation valve assembly is an important part of the ventilator, which mainly realizes functions such as pressure control, pressure monitoring, and flow monitoring of the patient during the exhalation phase. Because the gas flowing through the exhalation valve assembly is the gas exhaled by the patient, the exhalation valve assembly needs to be cleaned and disinfected before it can be used again. The current exhalation valve products mainly include an integrated flow acquisition module and two structures in which the flow acquisition module is independent of the exhalation valve assembly. The two structures mainly have the following technical defects: [0003] 1. The flow acquisition module is independent of the exhalation valve assembly. When connecting the patient pipeline, the connection operation of the flow acquisitio...
