Problems solved by technology

Because it is necessary to reduce some pressure when exhaling, which is conducive to the discharge of exhaust gas in the lungs, but the output pressure of the single-level ventilator is a constant and continuous positive pressure, which is not conducive to the discharge of exhaust gas; when inhaling, it is necessary to increase the flow to maintain pressure, but at this time The output pressure of the single-level ventilator remains unchanged

Embodiment Construction

[0017] A control method for improving the comfort of a ventilator, characterized in that it includes one of the following methods or a combination of several methods:

[0018] Method 1: Delayed pressure boost: The initial output pressure is the lowest pressure 4cmH2O that is easy for the patient to fall asleep, the delay setting time is 0~60min, and the output pressure gradually increases to the therapeutic pressure with the delay setting time;

[0019] Method 2: Heating compressed air: It has 5 heating gears of 20, 25, 30, 35 and 40°C, with a constant temperature heating temperature selection function, and adjusts the heating gear according to the ambient humidity to ensure that the humidity of the compressed air is stable. ;

[0020] Method 3: Expiratory phase pressure release technology for single-level ventilators: Real-time detection and identification of respiratory phases by pressure sensors and flow sensors, and 5 consecutive decremental pressure reductions at the end ...

Abstract

The invention discloses a control method for improving comfort of a breathing machine. The control method is characterized by comprising one following method or a combination of multiple following methods, and as for the first method, boosting is conducted in a delaying mode; as for the second method, compressed air is heated; as for the third method, the expiratory phase pressure releasing technique for one single horizontal breathing machine is adopted; as for the fourth method, the switching technique for triggering expiration pressure reducing and inhale pressure raising of autonomous respiration of double horizontal breathing machines is adopted. According to the control method for improving comfort of the breathing machine, the breathing machine is safe, reliable, high in sensitivity, and low in cost, effectively enhances comfort of a patient using the breathing machine, and is suitable for being generally popularized and applied.

Description

technical field [0001] The invention relates to a control method for improving the comfort of a ventilator, belonging to the field of medical equipment. Background technique [0002] Snoring is a ubiquitous sleep phenomenon. At present, most people think that it is commonplace, and they don't take it seriously. Some people regard snoring as a sign of a sound sleep. In fact, snoring is the enemy of health. At present, as people's awareness of poor breathing, such as snoring, can cause various diseases, ventilators are often used in family rehabilitation. The reasons for snoring can generally be divided into three types: one is due to the narrowing of the patient's airway, such as caused by diseases such as nasal polyps; the other is due to indoor hypoxia, which causes the patient to breathe with his mouth open during sleep; the third is sleep breathing controlled by autonomic nerves. Apnea syndrome, that is, snoring after suffocation for a while, this situation is very serio...
