Embodiment Construction

[0029] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0030] The present invention adopts a standard breathing rhythm generator for generating different breathing frequencies by simulating breathing actions based on a miniature speed-regulating air pump and an electromagnetic valve. Among them, the speed-regulating air pump is used to provide breathing power, and cooperates with the two-position four-way solenoid valve and the two-position three-way solenoid valve to realize the simulation of breathing action. The expiratory minute ventilation of the human lung is simulated by adjusting the flow rate of the air pump; the exhaled CO is realized by switching the channel of the two-position three-way solenoid valve. 2 Switching between gas and inhaled air; through the channel switching of the two-position four-way solenoid valve, the air flow direction switching between exhalation and inhal...

Abstract

The invention discloses a respiratory rhythm generator and a control method thereof. The respiratory rhythm generator structurally includes a two-position three-way solenoid valve, a two-position four-way solenoid valve, a speed-regulating air pump, an interface of a tested device, and a controller; a No.2 port of the two-position three-way solenoid valve is connected to a B port of the two-position four-way solenoid valve, an A port of the four-way solenoid valve is connected to the interface of the tested device, and a P port and a T port of the speed-regulating air pump are connected to a Pport and a T port of the two-position four-way solenoid valve correspondingly; and the controller performs gas control on the two-position three-way solenoid valve, direction control on the two-position four-way solenoid valve, and flow rate control of the speed-regulating air pump correspondingly. The problems of verification of two measurement parameters of the end-tidal carbon dioxide concentration and respiration rate of a multi-parameter monitor and the problems of calibration and quality inspection of an end-tidal carbon dioxide detector are solved. The respiratory rhythm generator is small in appearance and simple to operate, and on-site verification can be carried out in a hospital conveniently.

Description

technical field [0001] The invention relates to the technical field of human respiration simulation and verification, in particular to a respiration rhythm generator and a control method thereof. Background technique [0002] The multi-parameter monitor can provide important patient information for medical clinical diagnosis. Through various functional modules, it can detect important parameters such as ECG signal, heart rate, blood oxygen saturation, blood pressure, respiratory rate and body temperature in real time, and realize monitoring of various Monitoring and alarming of parameters, information storage and transmission, is an important device for monitoring patients. On December 31, 2019, the State Administration for Market Regulation promulgated JJG1163-2019 "Verification Regulations for Multi-parameter Monitors" for the first time, which will be officially implemented on March 1, 2020, and will include multi-parameter monitors in the national inspection catalog of m...
