Abstract

The invention discloses a method, device and system for detecting a breathing machine. The device comprises a simulated lung 10, a gas pressure sensor 8, a first gas passage 11 and a second gas passage 12, wherein the gas pressure sensor 8 is arranged in a third gas passage 13 which is connected with the simulated lung 10, and is used for detecting the gas pressure in the third gas passage 13; one end of the first gas passage 11 is connected to the third gas passage 13, and the other end of the first gas passage 11 is connected to an inspiration end 1 of the breathing machine; one end of the second gas passage 12 is connected to the third gas passage 13, and the other end of the second gas passage 12 is connected to an expiration end 2 of the breathing machine; and a first gas flow rate sensor 5 and a second gas flow rate sensor 6 are respectively arranged in the first gas passage 11 and the second gas passage 12. By using the invention, various parameters of the breathing machine can be better detected.

Description

technical field [0001] The invention relates to a detection method, equipment and system of a ventilator. Background technique [0002] The ventilator is a commonly used first aid and treatment equipment in clinical practice. It can provide respiratory support for patients, and can even completely replace the human body for ventilation. Since the ventilator is mainly used for critically ill patients, ensuring the stability and reliability of the ventilator is the prerequisite and requirement for reducing medical risks and ensuring medical safety. Before using the ventilator, the medical and health department must test and check the output parameters, reliability and safety performance of the ventilator. [0003] Ventilator testing equipment has been widely used in the field of medical engineering and medical equipment verification and measurement. Such as FLUKE's VT-PLUS and VT-Mobile, METRON's QA-VTM, Imtmedical's PF-300, and TSI's Certifier FAPlus. These detection devic...
