Pressure generator type identification method and device

Abstract

The invention discloses a pressure generator type recognition method. The method includes the steps of acquiring a pressure signal of an intake end of a pressure generator in a respirator, a pressure signal of an adnasal end of the pressure generator and a flow signal of gas flowing by the pressure generator; calculating a correspondence of the signals; acquiring feature relations among the intake end pressures and adnasal end pressures of various pressure generators, suitable for the respirator, and the flows of gas flowing by the pressure generators; comparing the correspondence with the feature relations of the pressure generators so as to determine the types of the pressure generators. The pressure generator type recognition method and device has the advantages that medical staff can directly use recognition results to accurately set the types of the pressure generators in the respirator, mistaken setting caused by the fact that the medical staff is not familiar with the types of the pressure generators in the respirator and safety is high. The invention further discloses the pressure generator type recognition device.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a pressure generator type identification method and device. Background technique [0002] Current ventilators (such as neonatal non-invasive nasal ventilators) can be divided into: (1) dual-line ventilators with mechanical exhalation valves, by controlling the pressure of the mechanical exhalation valves (2) A ventilator using a pressure generator to generate positive airway pressure by adjusting the flow rate. Ventilators using pressure generators are being used more and more clinically because they can monitor the pressure near the nasal end. [0003] Currently, there are many types of pressure generators suitable for ventilators, and different types of pressure generators have different correspondences between pressure and flow. Traditional ventilators cannot automatically identify the type of pressure generator. It is necessary for the medical staff to pre-set the...

AI Technical Summary

Problems solved by technology

Traditional ventilators cannot automatically identify the type of pressure generator. It is necessary for the medical staff to pre-set the type of pressure generator and ventilate after setting the flow or pressure according to the characteristics of the pressure and flow correspondence of the pressure generator. The operation is more troublesome.

Moreover, medical staff are not very clear about the characteristics of the flow and pressure correspondence of each pressure generator, which will lead to some clinical missettings and lead to abnormal pressure output of the ventilator, resulting in clinical risks
