Breathing machine and pressure control method

Abstract

The invention discloses a ventilator and pressure control method, comprising a casing, a turbine fan, a control device, a sensor, and a power supply device; wherein, the turbine fan is used for producing and outputting wind with certain pressure; the control device is connected with the turbine fan to control the operation of the turbine fan; the sensor is positioned at the pressure output end of the turbine fan; wherein, the feedback end of the sensor is connected with the control device; the power supply device is connected with each part for power supply; which is characterized in that: the pressure / flow rate is detected by the sensor, so that the control device can control the turbine fan according to the feedback of the sensor, and the ventilator can provide different output pressure when the user is under different breathing condition; by monitoring the resistance in the air passage during the sleeping process of the user, pressure can be raised according to need, so that the user will not feel uncomfortable. The ventilator has the advantages of simple structure, flexibility of regulating output pressure and ensured application effect.

Description

technical field [0001] The invention relates to a ventilator technology, in particular to a ventilator and a pressure control method for maintaining smooth breathing of patients with respiratory disorders in a sleeping state. Background technique [0002] At present, with the improvement of people's awareness of various diseases caused by poor breathing (such as snoring, etc.), the use of ventilators is becoming more and more popular. The ventilator is an artificial mechanical ventilation device, which is used to assist or control the patient's spontaneous breathing movement, so as to achieve the function of gas exchange in the lungs, reduce the consumption of the human body, and facilitate the recovery of respiratory function. [0003] The basic working principle of the ventilator is to use the pressure difference of the gas to work. According to the application, it can be divided into two categories, one is used to treat diseases of the respiratory system, and the other i...

AI Technical Summary

Problems solved by technology

If the patient has not fallen asleep after the set delay time, the higher therapeutic pressure will make the patient less tolerable; if the patient falls asleep earlier, the patient may experience airway collapse or hypoventilation because the pressure has not yet reached the therapeutic pressure. Did not achieve therapeutic effect

In addition, since this method reaches the preset time, the therapeutic pressure output by the ventilator will be higher for awake patients, causing discomfort, and it will also cause a certain psychological burden for some patients to fall asleep, affecting normal sleep.

[0015] (2) The disadvantages of AutoCPAP are as follows: ① During the whole sleep process, due to the frequent changes in airway resistance, the patient continuously increases and decompresses the pressure, resulting in more pressure fluctuations and affecting sleep quality

② Inadequate treatment

In this way, especially for heavier patients, the cumulative time for patients with greater airway resistance during treatment will be more

In addition, the current method for judging airway resistance is still insufficient to a certain extent. During AutoCPAP therapy, some patients often suffer from hypoventilation.

[0016] In summary, due to the inability of the existing ventilator to perform accurate pressure control, it cannot fully meet the requirements for the treatment of sleep apnea hypopnea syndrome
