Embodiment 1

[0045] A specific embodiment of the present invention discloses a medical nitric oxide gas supply system, such as figure 1 As shown, the medical nitric oxide gas supply system includes a nitric oxide gas generation subsystem and a gas concentration monitoring subsystem. Both the nitric oxide gas generation subsystem and the gas concentration monitoring subsystem are connected to the inhalation of the user terminal 23. The pipeline is connected, where the inhalation pipeline is connected with mechanical ventilation equipment such as ventilator, anesthesia machine, oxygen generator or oxygen inhaler or oxygen inhalation equipment 22; the nitric oxide gas generation subsystem is used to produce nitric oxide gas ; The gas concentration monitoring subsystem is used to monitor the user's actual inhaled nitric oxide and nitric oxide concentration, and take the actual inhaled nitric oxide monitoring value as the target to feedback control the nitric oxide gas concentration output by the ...

Embodiment 2

[0058] A specific embodiment of the present invention discloses a medical nitric oxide gas supply method, which specifically uses the medical nitric oxide gas supply system in the first embodiment to supply gas, including the following steps:

[0059] Step 1: Nitric oxide generation;

[0060] The suction pump 2 is started, and the monitoring result of the first flow monitoring device 4 is used as the target to feedback and control the suction pump 2 to ensure that the suction pump 2 outputs a continuous and stable air flow. The air output by the suction pump 2 enters the nitric oxide generator 5 through the air filter 3, and the nitric oxide generator 5 is activated to generate nitric oxide gas, and the generated nitric oxide gas passes through the nitrogen dioxide filter 8 and then passes through the air The interface 12 flows into the suction pipe;

[0061] Step 2: Monitoring and control of nitric oxide concentration;

[0062] Start the suction pump 2 at the same time, or start the...

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...
