Problems solved by technology

The flow and pressure inhalation trigger methods of the ventilator are widely used in invasive ventilators, but are rarely used due to the characteristics of air leakage in non-invasive ventilators. In addition, in the diaphragmatic electric inhalation trigger, a sensor needs to be placed through the nose. Into the stomach, the sensor can transmit the electronic signal of the diaphragm to the ventilator, and the ventilator performs synchronous inhalation and air delivery according to the signal. The disadvantage of this method is that the cost of clinical detection of the sensor is high, which leads to high cost of breath detection. And the clinical operation is complicated

Abstract

The invention discloses an inhalation trigger control method. The inhalation trigger control method includes the following steps: detecting first pressure information of an air bag preset on an object to be measured; The standard value determines the respiration state of the object to be measured; when the respiration state is an inhalation state, an inhalation trigger control signal is output. The invention also discloses an inhalation trigger control device. The invention reduces the cost of breathing detection, and realizes reliable recognition of inspiratory triggering in a non-invasive ventilator.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to an inhalation trigger control method and device. Background technique [0002] At present, in medical equipment, in order to realize the synchronous detection of the patient's breathing, the flow rate, pressure of the ventilator, and the triggering of diaphragm electric inspiration are mainly used. The flow and pressure inhalation trigger methods of the ventilator are widely used in invasive ventilators, but are rarely used due to the characteristics of air leakage in non-invasive ventilators. In addition, in the diaphragmatic electric inhalation trigger, a sensor needs to be placed through the nose. Into the stomach, the sensor can transmit the electronic signal of the diaphragm to the ventilator, and the ventilator performs synchronous inhalation and air delivery according to the signal. The disadvantage of this method is that the cost of clinical detection of the sen...
