Abstract

The invention relates to a method and device for correcting the airway pressure of a breathing machine and the breathing machine; the breathing machine comprises at least one digital pressure sensor and a plurality of simulation pressure sensors, and the method comprises the steps: judging whether the simulation pressure sensors have pressure measurement deviation or not; if the pressure measurement deviation exists, obtaining a standard airway pressure value output by the digital pressure sensor; and performing deviation zeroing correction on the simulation pressure sensors according to the standard airway pressure value. Compared with the prior art, the method has the advantages that the deviation of the simulation pressure sensors can be quickly subjected to zero correction, the accuracy of airway pressure detection is improved, and the problem of abnormal control of the breathing machine is avoided.

Description

technical field [0001] The embodiments of the present application relate to the technical field of ventilators, and in particular, to a method and device for correcting airway pressure of a ventilator, and the ventilator. Background technique [0002] As a device that can artificially replace the function of spontaneous ventilation, the ventilator has been widely used in respiratory failure caused by various reasons, anesthesia breathing management during major surgery, respiratory support treatment and emergency resuscitation, and occupies a very important role in the field of modern medicine. important position. [0003] In the clinical use of the ventilator, it is necessary to continuously detect the pressure in the airway of the ventilator in order to realize the control of the ventilation flow of the ventilator. However, due to factors such as airflow disturbance, temperature, and inaccurate calibration of the pressure sensor itself, the accuracy of airway pressure det...
