Embodiment 1

[0022] Embodiments of the present invention provide a ventilator, such as figure 1 and figure 2 As shown, the ventilator includes a mask 1, an inspiratory airbag 2, an exhalation airbag 3, an extruding mechanism, a driving mechanism and a controller, and the mask 1 is provided with a trachea 11; the inspiratory airbag 2 includes a first one-way air inlet 21 and The first one-way air outlet 22 connected to the trachea 11; the exhalation air bag 3 includes a second one-way air outlet 32 ​​and a second one-way air inlet 31 connected to the air tube 11; The fixed part 41 on the airbag 3, and the movable part 42 arranged on the inhalation airbag 2 and the exhalation airbag 3, the fixed part 41 and the movable part 42 are all arranged oppositely on the inhalation airbag 2 and the exhalation airbag 3; the driving mechanism It is used to push the moving part 42 to the fixed part 41 or pull the moving part 42 away from the fixed part 41; the controller is used to control the driving ...

Embodiment 2

[0041] image 3 It is a flow chart of the ventilator control method provided by Embodiment 2 of the present invention. The technical solution of this embodiment is applicable to the situation of controlling the ventilator described in the foregoing embodiments. This method can be executed by the controller in the foregoing embodiments, combined with figure 1 , figure 2 and image 3 , the method specifically includes the following steps:

[0042] S1. Control the driving mechanism to push and pull the moving parts based on the preset sequence, and compress the volumes of the inhalation airbag and the exhalation airbag through the push movement, so that the inhalation airbag can input the target gas to the mask and the exhalation airbag can pass through the second unit. Exhaust the waste gas in the self bag to the air outlet.

[0043] Wherein, the preset time sequence is determined by the controller according to the breathing parameters input by the user. Wherein, the resp...

Abstract

The embodiment of the invention discloses a breathing machine and a control method of the breathing machine. The breathing machine comprises: a mask provided with an air tube; an inspiratory air bag which comprises a first one-way air inlet and a first one-way air outlet connected to the air tube; an expiratory air bag which comprises a second one-way air outlet and a second one-way air inlet connected to the air tube; an extrusion mechanism which comprises a fixed piece and a moving piece which are simultaneously arranged on the inspiratory air bag and the expiratory air bag, wherein the fixed piece and the moving piece are oppositely arranged on the inspiratory air bag and the expiratory air bag; and a controller which controls a driving mechanism to perform push-pull motion on the moving piece based on a preset time sequence. Through pushing movement, the inspiratory air bag inputs target gas into the mask and the expiratory air bag discharges exhaust gas in the self-bag through thesecond one-way air outlet; and through pulling movement, the inspiratory air bag sucks the target gas into the self-bag through the first one-way air inlet and the expiratory air bag sucks the exhaust gas in the mask into the self-bag. The invention solves the problem that breathing machines in the prior art are at least complex in structure.

Description

technical field [0001] Embodiments of the present invention relate to the field of medical equipment, in particular to a ventilator and a control method for the ventilator. Background technique [0002] The ventilator can help the human body physiologically change breathing, increase lung ventilation, and effectively improve respiratory function. The current ventilators mainly include medical ventilators and home ventilators. Medical ventilators are mainly used in the treatment of surgery, first aid and respiratory diseases; home ventilators are mainly used for home treatment of mild patients. But no matter what kind of ventilator, the structure is relatively complicated, and the price is relatively expensive, making it unaffordable for many families or hospitals in poor areas. [0003] To sum up, at least the ventilator in the prior art has the problem of relatively complicated structure. Contents of the invention [0004] The embodiment of the present invention provide...
