Title:
HANDHELD EXHALED GAS COLLECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/000850
Kind Code:
A1
Abstract:
A handheld exhaled gas collection device, comprising: a gas intake/discharge mechanism, a gas detection mechanism, a rotary valve (3) and a gas collection mechanism that are sequentially connected, and further comprising sensors (201, 202), a main processor and a blowback mechanism. The sensors (201, 202) are disposed on an outer side of the gas detection mechanism, and the sensors (201, 202) are used to detect state parameters of an inhaled gas and transmit the collected data to the main processor. The blowback mechanism is used to suction in outside air and discharge same from the air intake/discharge mechanism by means of an exhaled gas passage. The main processor can, on the basis of the state parameters of the inhaled gas, control the rotary valve (3) to rotate, thereby changing the connected/disconnected state of the exhaled gas passage. The gas intake/discharge mechanism is used to filter water vapor in exhaled gas. The gas collection mechanism is used to externally connect a gas collection container so as to complete the collection of exhaled gas. The handheld exhaled gas collection device has low gas resistance and is lightweight.
