Problems solved by technology
Existing high-frequency ventilators usually use compressed air as the air source due to the requirement for input pressure. However, in some specific rescue environments, there is often a lack of compressed air source, and a turbo fan is used to drive the gas. When the turbo fan When the rotation speed changes, if the amplitude of the high-frequency oscillation module remains constant, the pressure on the patient end may be relatively high.

The invention provides a method and a device for controlling a high-frequency oscillation module and a high-frequency breathing machine, and relates to the technical field of breathing machines. The method for controlling the high-frequency oscillation module comprises the following steps of: acquiring rotation parameters of a turbine fan and patient end pressure in real time; determining the amplitude change interval of the high-frequency oscillation module according to the rotation parameters of the turbine fan and the patient end pressure; performing amplitude rise control on the high-frequency breathing machine in the amplitude change interval; when the patient end pressure reaches the set condition, allowing the high-frequency breathing machine to stop executing the amplitude rise control; and controlling the high-frequency oscillation module according to the amplitude and the oscillation frequency. The method for controlling the high-frequency oscillation module controls the amplitude rise of the high-frequency oscillation module and acquires the patient end pressure. When the rotating speed of the turbine fan changes, the amplitude is reconfirmed, so that the amplitude change control of the breathing machine is realized, and the risk of air pressure increase caused by unstable work of the turbine fan is reduced.
Description
technical field [0001] The invention relates to the technical field of ventilators, in particular to a control method and device for a high-frequency oscillation module and a high-frequency ventilator. Background technique [0002] The high-frequency ventilator is a respiratory device designed for artificial mechanical ventilation for patients who need to provide respiratory support, respiratory therapy and emergency resuscitation. It usually uses a high-pressure air source to provide artificial mechanical ventilation for patients who need to provide respiratory support, respiratory therapy and emergency resuscitation. Existing high-frequency ventilators usually use compressed air as the air source due to the requirement for input pressure, but in some specific rescue environments, there is often a lack of compressed air source, and a turbo fan is used to drive the gas. When the turbo fan When the rotational speed changes, if the amplitude of the high-frequency oscillation m...
