Abstract

The invention discloses an intelligent start-stop method and device and a breathing machine. The intelligent start-stop method comprises the steps that step one, a pressure signal and a flow signal ofa user side are collected; step two, air velocity V, differential pressure Delta P and air leakage V<leak> of the user side are separately obtained according to the flow signal and the pressure signal; and step three, if a halted state is located at present and the flow velocity is greater than a first threshold value delta<1> or less than a second threshold value delta<2>, intelligent starting is started. According to the intelligent start-stop method and device and the breathing machine, intelligent start-stop is realized by identifying breathing airflow of a user, the operational process of the user is simplified, the using efficiency of the equipment is improved, the operating life of the equipment is prolonged, and energy conservation and environment protection are achieved.

Description

technical field

[0001] The invention relates to the technical field of intelligent control, in particular to an intelligent start-stop method, device and ventilator. Background technique

[0002] Ventilator is a device that can replace, control or change people's normal physiological breathing, increase lung ventilation, improve respiratory function, reduce respiratory function consumption, and save heart reserve capacity. The sleep apnea machine (or non-invasive ventilator) continuously provides oxygen to the patient through a given pressure, so as to improve the hypoxia problem of the patient during sleep. The sleep apnea machine is mainly used to treat sleep apnea syndrome, that is, severe snoring and the accompanying symptoms of suffocation, and it can also treat complications of sleep apnea syndrome, improve the blood oxygen concentration of the user during night sleep, and treat Hypoxemia etc.

[0003] In the prior art, during the use of the ventilator, the main unit...
