[0042] Inhalation therapy refers to providing breathing gas containing therapeutic gas to a patient through a mechanical ventilation device such as a ventilator to achieve a therapeutic effect. Taking nitric oxide gas as an example, nitric oxide plays a role in transmitting important signals and regulating cell functions in the human body; it helps to promote blood circulation in the body. Nitric oxide can rapidly diffuse through biological membranes without any intermediate mechanism, transmitting information generated by one cell to surrounding cells. Nitric oxide has multiple biological functions and can participate in electron transfer reactions and redox processes in the human body at any time. Direct inhalation of nitric oxide therapy as a treatment for persistent pulmonary hypertension of the newborn has proven to be effective in improving the oxygenation capacity of the body and reducing the need for high-risk extracorporeal life support for critically ill patients. Controlled and appropriate inhalation of nitric oxide can effectively reduce pulmonary hypertension and improve oxygenation. Currently, nitric oxide inhalation therapy has been widely used in neonatal respiratory medicine and is also applicable to clinical medical fields such as intensive care, cardiothoracic surgery, respiratory medicine, and anesthesiology. Therapeutic gases such as nitric oxide are usually ventilated in cooperation with mechanical ventilation devices such as ventilators and anesthetic machines. In the prior art, the nitric oxide therapy device and the mechanical ventilation device are usually two independent devices.
