Problems solved by technology

In the process of boosting or depressurizing, make the solenoid valve fully operate, such as accelerating the pressure of the ventilator to reach the preset value within a fixed time. Although this method can meet the needs of rapid pressure changes, it is comfortable for users to use. Sexuality will bring more serious effects, for example, the airflow that becomes high pressure in a short time will have a serious impact on the user's entire airway, and even cause certain barotrauma

Embodiment Construction

[0035]The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0036] like figure 1 as shown, figure 1 It is a schematic flowchart of an embodiment of a method for adaptive adjustment of a ventilator according to the present invention. The method for adaptive adjustment of a ventilator includes the following steps:

[0037] Step S1, receiving the pressure IPAP, pressure EPAP set by the user on the ventilator, and the maximum speed V of the solenoid valve of the ventilator max , The time T of the solenoid valve of the ventilator running in the acceleration phase 1 And the time T that the solenoid valve of the ventilator operates in the deceleration phase 3 ;

[0038] Step S2, when it is recognized that the user is currently inhaling or exhaling, according to the pressure IPAP...

Abstract

The invention relates to an adaptive adjustment method for a respirator. The adaptive adjustment method for the respirator includes the steps: receiving pressure IPAP and pressure EPAP set on the respirator by a user, the maximum running speed Vmax of a solenoid valve of the respirator, running time T1 of the solenoid valve at an accelerating stage and running time T3 of the solenoid valve at a decelerating stage; controlling the solenoid valve to sequentially run in an accelerating manner, run at a uniform speed, run in a decelerating manner and open or close according to the pressure IPAP, the pressure EPAP, the maximum speed Vmax, the time T1 and the time T3 when recognizing current inhaling action or exhaling action of the user. The pressure can be rapidly boosted or reduced, pressure vibration of the solenoid valve is avoided in opening and closing as buffer is subsequently performed at a uniform-speed stage and the decelerating stage after acceleration, excellent use comfort is provided for the user, and optimal efficacy is achieved.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a ventilator self-adaptive adjustment method and the ventilator. Background technique [0002] When the user is breathing, the ventilator can identify the user's inhalation or exhalation action according to a certain method. If it is an inhalation action, the ventilator provides a higher IPAP pressure to flow the gas into the user's body. Action, the ventilator drops the pressure from IPAP to EPAP, allowing the user to exhale smoothly. [0003] At present, regardless of whether the pressure is increased or decreased, the ventilator generally adjusts the pressure to a preset value within a fixed time, for example: increase the pressure from 4cmH2O to 10cmH2O within 200ms, or increase the pressure from 4cmH2O to 30cmH2O within 200ms. In the process of boosting or depressurizing, make the solenoid valve fully operate, such as accelerating the pressure of the ventilator to...
