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.

Embodiment Construction
[0043] It should be noted that, in the case of no conflict, the embodiments and features in the embodiments of the present invention can be combined with each other. The present invention mainly protects a ventilation control method, and specifically relates to a correction method of the ventilation method. The method is based on the high-frequency ventilator system described in the embodiments herein.
[0044] In addition, the orientation descriptions such as "in" and "between" mentioned in the embodiments of the present invention do not refer to between and among in structure, but between and between in terms of gas path relationship. In the text, the interconnected structures involved in the text are connected through pipelines. In addition, the description of words such as "first" and "second" in the text does not constitute a limitation on the specific number, but is for the convenience of understanding the present invention. Simplified description and distinction should ...

The invention provides a control method and device of a high-frequency oscillation module and a high-frequency ventilator, and relates to the technical field of ventilators. The control method of the high-frequency oscillation module of the present invention includes: acquiring the rotational parameters of the turbo blower and the pressure on the patient side in real time; determining the amplitude variation interval of the high-frequency oscillation module according to the rotational parameters of the turbo blower and the pressure on the patient side; The high-frequency ventilator is controlled by the amplitude; when the pressure on the patient end reaches the set condition, the high-frequency ventilator stops performing the amplitude control; the high-frequency oscillation module is controlled according to the amplitude and oscillation frequency. The control method of the high-frequency oscillation module of the present invention controls the amplitude of the high-frequency oscillation module, obtains the pressure at the patient end, and re-confirms the amplitude when the rotational speed of the turbo blower changes, thereby realizing the amplitude variation of the ventilator. Control, reducing the risk of increased air pressure caused by unstable operation of the turbine fan.
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...
