Adaptive Calibration System and Method for Transnasal Pressure Generator

Abstract

Provided are a system and method for adaptive calibration of a nasal pressure generator; a flow measurement apparatus (110) measures the flow into a nasal continuous positive-airway-pressure ventilator; a pressure measurement apparatus (120) is used for measuring the airway pressure of a pressure generator (140); a control apparatus (130) obtains first measurement data and second measurement data corresponding to flow and pressure, records the corresponding largest first measurement data when the second measurement data is equal to the largest pressure threshold value, and the corresponding smallest first measurement data when the second measurement data is equal to the smallest pressure threshold value, and according to a certain interval, extracts a number N of first measurement data from the range of first measurement data; the control apparatus (130) separately controls the flows into the ventilator for the corresponding number N of first measurement data, obtaining a number N of second measurement data corresponding to the first measurement data, and establishes a table of correlations between the number N of second measurement data and the number N of first measurement data to obtain the correlation between flow and pressure; thus the pressure output is rapidly and accurately controlled, reducing risk in clinical use.

Description

technical field [0001] The invention relates to medical instruments, in particular to an adaptive calibration system and method for a nasal pressure generator. Background technique [0002] Neonatal nasal continuous positive airway pressure ventilator is generally divided into two types, one is the mechanical pressure regulating valve to achieve airway pressure, its working principle is to use double breathing tubes to connect nasal plugs, one end is the air inlet, The other end is connected to a mechanical pressure regulating valve, and the pressure valve is manually adjusted to realize airway pressure regulation. The other type is the pressure generator type. Its working principle is to use a single breathing circuit to connect the pressure generator, the pressure generator is connected to the patient, and the airway pressure can be adjusted by adjusting the flow rate of the pressure generator. [0003] The traditional nasal continuous positive airway pressure ventilator ...
