Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a nitric oxide connecting device for treating pulmonary hypertension. Background Art

[0002] Pulmonary hypertension is a life-threatening disease caused by a variety of reasons that lead to malignant increase in pulmonary vascular resistance, resulting in pulmonary vascular remodeling, and gradually develops into right heart failure and death. NO (nitric oxide) is an important endogenous bioactive molecule. NO dilates blood vessels by increasing cGMP (cyclic guanosine monophosphate) in vascular smooth muscle cells. In the disease state, endothelial cells cause changes in blood flow or blood pressure due to NO metabolic disorders.

[0003] The treatment of primary pulmonary hypertension by inhalation of exogenous NO has been successful, and it has been found that inhaled NO has a dose-dependent pulmonary vasodilation effect, which can reduce pulmonary vascular resistance and pulmonary artery pressure. This has triggered extensive international research on the use of inhaled NO for pulmonary hypertension-related diseases. Cylinder gas supply is common in clinical applications, and clinical connection and control are controlled by oxygen devices, lacking precise concentration calculations, and no monitoring of the generated nitrogen dioxide, which can easily cause toxic side effects and damage the patient's lung tissue.
