Medical nitric oxide gas supply system and medical nitric oxide air supply method

Abstract

The invention relates to a medical nitric oxide gas supply system and a medical nitric oxide air supply method, belongs to the technical field of medical instruments and solves the problems in an existing nitric oxide gas supply system that feedback regulation and control on output of a nitric oxide gas supply system are difficult to realize by taking the concentration of nitric oxide required tobe inhaled by a user as a target and the treatment cost is high. The medical nitric oxide gas supply system comprises a nitric oxide gas generation subsystem and a gas concentration monitoring subsystem, wherein the two subsystems are communicated with a gas inhalation pipeline; the nitric oxide gas generation subsystem is used for producing nitric oxide gas; the gas concentration monitoring subsystem is used for monitoring the concentration of the nitric oxide and nitrogen dioxide which are actually inhaled by the user and feeding back and controlling the concentration of the nitric oxide gasoutput by the nitric oxide generation subsystem by taking the monitoring value as a target. The invention also provides a medical nitric oxide gas supply method. The medical nitric oxide gas supply system disclosed by the invention can be combined with various oxygen uptake equipment and mechanical ventilation equipment for use, the concentration of the nitric oxide actually inhaled by the user can be monitored and regulated in real time, reaching a set target range.

Description

Technical field [0001] The present invention relates to the technical field of medical devices, in particular to a medical nitric oxide gas supply system and method. Background technique [0002] Nitric oxide, also known as vascular endothelial cell relaxation factor, can be produced by vascular endothelial cells and act as a signal molecule to regulate the activities of other cells and improve the function of vascular endothelial cells. Inhaling a certain concentration of nitric oxide can selectively expand the pulmonary blood vessels, relax the smooth muscles of the trachea and bronchus, reduce the pressure of the pulmonary artery, improve the pulmonary blood circulation and oxygenation, and has the advantages of fast curative effect, non-invasive and high selectivity, which is not only successful It is used in the treatment of neonatal persistent hypoxemia and pulmonary hypertension, and it has also been increasingly used in the treatment of adult acute respiratory distress sy...

AI Technical Summary

Problems solved by technology

[0005] In view of the above analysis, the present invention aims to provide a medical nitric oxide gas supply system and method to solve the problem that the existing nitric oxide gas supply system is difficult to achieve the target feedback adjustment and Control the output of the nitric oxide gas supply system, and cannot synchronize the intermittent output of nitric oxide gas with the breathing cycle, so that it cannot be used in conjunction with mechanical ventilation equipment and the problems of high treatment cost and difficult maintenance
