Abstract

The invention is applicable to the field of medical appliances and provides a ventilating system of an anesthesia apparatus and a pressure calibration method thereof. In the embodiment of the invention, pressure acquisition points of a valve seal pressure sensor are arranged in a cavity between an air box and a folding bag, so that the acquired pressure is more accurate; and an air control expiratory valve is changed into an electric control expiratory valve based on a voice coil motor. The invention also provides a pressure calibration method based on an improved air passage, which uses an air passage pressure gauge and a graphical calibration interface of the anesthesia apparatus respiratory system to calibrate all the pressure sensors in the apparatus, thereby realizing fast calibration without disassembling the apparatus and fast calibration of pressure-free calibration equipment, saving the calibration time and lowering the maintenance cost of the apparatus.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to an anesthesia machine ventilation system and a pressure calibration method thereof. Background technique [0002] figure 1 The structure of the ventilation system of the anesthesia machine provided by the prior art is shown, the ventilation system includes: a bellows 1, a folding bag 2 built in the bellows 1, an exhalation one-way valve 3, an exhalation flow sensor 4, an air-controlled exhalation Valve 5, absorption tank 6, patient port 7, inspiratory one-way valve 8, inspiratory flow sensor 9, airway pressure gauge 10, valve sealing pressure sensor 11, airway pressure sensor 12, electrical monitoring module 13, man-machine interface 14. [0003] The air-controlled exhalation valve 5, valve sealing pressure sensor 11, airway pressure sensor 12, and electrical monitoring module 13 are generally placed inside the anesthesia machine, and cannot be accessed without disa...
