Nitric oxide therapeutic apparatus

Abstract

Disclosed is a nitric oxide therapeutic apparatus. The nitric oxide therapeutic apparatus comprises a housing, the inside of the housing is fixedly provided with a NO control module, a detecting module, a power module and a control module, wherein the control module is electrically connected with the power module; the NO control module comprises a mass flow controller; the detecting module comprises a gas pump, detecting sensors and a three-way electromagnetic valve; the detecting sensors are composed of a NO detecting sensor and a NO2 detecting sensor; the outlet pipes of three-way electromagnetic valve include and a detecting gas path and a set gas path, the detecting gas path is communicated with the gas pump and the detecting sensors, and the set gas path is communicated with the atmosphere; the detecting sensors, the mass flow controller and the three-way electromagnetic valve are all electrically connected with the control module. According to the nitric oxide therapeutic apparatus, the specially arranged set gas path is used for setting zero of the sensors to avoid influence of residual therapeutic gas in pipes on the detecting values of the sensors, so that the nitric oxidetherapeutic apparatus can be more accurate in detection.

Description

technical field [0001] The invention relates to a medical device, in particular to a nitric oxide therapeutic instrument. Background technique [0002] Inhalation of nitric oxide (NO) is a new respiratory emergency technology that has been used clinically since the 1990s. It has been paid attention to because of its advantages of quick curative effect, non-invasiveness and high selectivity. At present, NO has been used more and more clinically as a new method for the treatment of acute respiratory failure syndrome, hypertension and some lung-related diseases. It is especially used for the treatment of persistent pulmonary hypertension of the newborn (PPHN), acute respiratory distress syndrome (ARDS), congenital heart disease with pulmonary hypertension (CHD+PH), bronchopulmonary dysplasia (BPD) and high altitude pulmonary edema (HAPE), etc. [0003] In the traditional nitric oxide treatment instrument, the detection sensor has only one detection gas path. Since the therapeu...

AI Technical Summary

Problems solved by technology

[0003] In the traditional nitric oxide treatment instrument, the detection sensor has only one detection gas path. Since the therapeutic gas may remain in the pipeline, the zero return of the detection sensor is inaccurate when the instrument is restarted or turned on, resulting in inaccurate detection results and affecting The patient's therapeutic effect even endangers the patient's health
