Self-adaptation calibration system and method for passing-nose pressure generator

Abstract

The invention discloses a self-adaptation calibration system and method for a passing-nose pressure generator. A flow measurement device conducts detection on flow flowing into a passing-nose nasal continuous positive airway positive pressure ventilation breathing machine; a pressure detection device is used for detecting the airway pressure of the pressure generator; a control device obtains first detection data and second detection data corresponding to the flow and the pressure and records the maximum first detection data, equal to the maximum pressure threshold value, in the second detection data and the minimum first detection data, equal to the minimum pressure threshold value, in the second detection data, and N first detection data are extracted according to a certain interval within the section of the first detection data; and the control device controls the flow flowing into the breathing machine to be N corresponding first detection data, obtains the N second detection data corresponding to the N first detection data and builds the congruent relationship table between the N second detection data and the N first detection data; the congruent relationship between the flow and the pressure is obtained, pressure output accurate control is rapidly achieved, and the clinic using risks are reduced.

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 ...
