Embodiment Construction

[0030] The present invention will be described in detail below in conjunction with the accompanying drawings. The description in this part is only exemplary and explanatory, and should not have any limiting effect on the protection scope of the present invention. In addition, those skilled in the art can make corresponding combinations of features in the embodiments in this document and in different embodiments according to the descriptions in this document.

[0031] An example of the present invention is as follows, a method for adjusting the pressure of a ventilator fan, which adjusts the output pressure of the ventilator by controlling the speed of the fan, specifically including accelerating the speed of the fan when inhaling, so that the output pressure of the ventilator changes rapidly from EPAP to EPAP. Rise to IPAP; when exhaling, accelerate and reduce the speed of the fan, so that the output pressure of the ventilator quickly decreases from IPAP to EPAP. In this way, ...

Abstract

The invention provides a method for adjusting the pressure of a draught fan of a respirator. The output pressure of the respirator is adjusted by controlling the rotating speed of the draught fan. The method specifically includes the steps that during inhalation, the rotating speed of the draught fan is accelerated to be increased, and the output pressure of the respirator is rapidly increased to IPAP from EPAP; during exhalation, the rotating speed of the draught fan is accelerated to be decreased, and the output pressure of the respirator is rapidly reduced to EPAP from IPAP. Thus, the rotating speed of the draught fan is accelerated to be adjusted, and therefore the output pressure of the respirator can be rapidly increased to IPAP from EPAP or reduced to EPAP from IPAP within the preset time. The preset time can be set to be 0.1 S to 2 S according to user requirements, a user breathes more smoothly, and the use comfort for the user is improved.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a method for adjusting the pressure of a blower fan of a ventilator. Background technique [0002] In modern clinical medicine, the ventilator, as an effective means of artificially replacing the spontaneous ventilation function, has been widely used in respiratory failure caused by various reasons, anesthesia respiratory management during major surgery, respiratory support treatment and emergency resuscitation. It occupies a very important position in the field of modern medicine. Ventilator is a vital medical equipment that can prevent and treat respiratory failure, reduce complications, save and prolong the life of patients. [0003] A ventilator is a medical device designed to output air at a certain pressure or flow rate to assist patients with respiratory insufficiency or who cannot breathe spontaneously due to special circumstances. The motor-driven turbo blower is the ...
