Intelligent adjustable one-way exhaust device

Abstract

The invention relates to an intelligent adjustable one-way exhaust device, which includes a valve body, a valve cover, an air inlet, an outlet, an exhaust, a control chamber, a reversing chamber, an exhaust chamber and a reversing spool. The invention provides a reversible pressure breathing valve between a non-invasive ventilator and a face mask; when the patient inhales, the ventilator providespositive pressure gas to the patient, Guaranteeing patient airway openness, so that that patient is smoothly inhale, patient expiratory time, At that same time, an air outlet with adjustable open sizeis arranged on the breathe valve, so as to maintain a certain pressure in the respiratory tract of the patient by adjusting the size of the air outlet, thereby avoiding the occurrence of respiratorytract collapse, so that the non-invasive ventilator with single-loop air supply can meet the needs of the patient with lung problems.

Description

Technical field: [0001] The invention belongs to the technical field of medical auxiliary equipment, and in particular relates to a universal intelligent adjustable one-way exhaust device for a single-level ventilator and a double-level ventilator. Background technique: [0002] In recent years, more and more patients with neuromuscular diseases (Green-Barré, peripheral nerve disease, myasthenia gravis, etc.) have been clinically diagnosed. Such diseases often have a long course of disease and are difficult to cure, eventually leading to respiratory muscle disorders, paralysis, and inability to breathe on a load. Exercise, showing clinical manifestations of respiratory failure and weak cough. Clinical treatment is mostly supported by tracheotomy, invasive ventilator-assisted breathing (double loop), sputum drainage, and anti-infection. However, these patients are forced to live in the ICU because of the support of the ventilator. From the patient's point of view, it serious...

Problems solved by technology

However, the price of a single-level non-invasive ventilator is 5,000 to 10,000 yuan / unit, while the price of a dual-level non-invasive ventilator is 15,000 to 50,000 yuan / unit. Although the effect of home non-invasive ventilators in treating diseases has been recognized, and It is being promoted nationwide, but the high price forces many families to only purchase single-level non-invasive ventilators, and the clinical compliance of single-level ventilators is poor, and most patients cannot tolerate them, resulting in giving up the opportunity to treat diseases with non-invasive ventilators
