Problems solved by technology

[0007] The above-mentioned flowmeter is used as an airflow flowmeter, especially when the airflow has a certain humidity, and the water droplets generated by the condensation of the wet airflow will easily flow into the detection device through the pressure measuring tube, causing detection errors or damage to the detection device.

Abstract

The invention discloses a detection device for a lung function tester. The detection device comprises a detection assembly and a pressure difference collection assembly; the pressure difference collection assembly comprises a venturi tube, and the periphery wall of the venturi tube is provided with a pressure guide hole and a joint assembly communicated with the pressure guide hole; the connectorassembly is provided with a pressure guide flow channel, and the pressure guide flow channel at least comprises an anti-water-accumulation part with a U-shaped cross section. Through an airflow channel of a U-shaped structure, the wet airflow entering the airflow channel is condensed through the U-shaped airflow channel, water drops are collected at the bottom of the U-shaped airflow channel and effectively prevented from entering a detection device circuit, and the technical problem is solved that since the water drops enter the device, detection errors are caused, or the device is damaged.

Description

technical field [0001] The invention relates to a lung function detection device applicable to the technical field of medical devices, in particular to a lung function detection device using a Venturi tube. Background technique [0002] Vital capacity is closely related to human breathing and lung function. Physiological studies have shown that all organs, systems, tissues, and cells of the human body consume oxygen all the time, and the body can only work normally when the oxygen supply is sufficient. The oxygen supply inside the human body is all obtained by the breathing of the lungs. During the breathing process, the lungs not only need to take in oxygen, but also expel the carbon dioxide metabolized in the body. We can think of it this way: the lung is a transfer station for the body's gas exchange, and the volume of this transfer station directly determines the amount of gas exchange in each breath, which is the most intuitive and objective indicator for testing lung ...
