Embodiment Construction
[0041] In order to make the object, technical solution and advantages of the present invention more clear and definite, the present invention will be further described in detail below with reference to the accompanying drawings and examples.
[0042] Such as figure 1As shown, the respiratory pressure control system of the ventilator provided by the present invention includes: a pressure follower, an exhalation and inhalation discriminator, and a pressure drop-off device, and the pressure follower is divided into a first pressure follower and a second pressure follower . The first pressure follower is mainly used in the inhalation state to maintain the pressure at the set target therapeutic pressure level, and the greater the deviation between the current pressure and the target therapeutic pressure, the faster the adjustment rate. The second pressure follower is mainly used in the exhalation state to maintain the pressure at the set target therapeutic pressure level, and the ...
