Abstract

The invention provides a high-frequency respirator system and a ventilation control method, and relates to the technical field of respirators. The ventilation control method of the high-frequency respirator system provide by the invention comprises the following steps: S1, acquiring the input frequency of the high-frequency respirator; and S2, when the input frequency is higher than the set frequency, starting a turbine fan, starting a high-frequency oscillation module, starting an exhalation fan, starting a breathing valve, and performing breathing valve control, wherein the breathing valve control comprises: when a patient inhales, controlling the opening degree of the breathing valve to be reduced, and when the patient exhales, controlling the opening degree of the breathing valve to beincreased. According to different input frequencies, high-frequency ventilation and constant-frequency ventilation are respectively carried out, and ventilation control on a patient is realized through the combined action of the turbine fan and the exhalation fan. In addition, by closing the breathing valve at the time of inhalation and opening the breathing valve at the time of exhalation, the inhalation and exhalation effects of the patient are better.

Description

technical field [0001] The invention relates to the technical field of ventilators, in particular to a high-frequency ventilator system and a control method. 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. Contents of the invention [0003] The present invention has been made in view of the state of the prior art described above, and an object of the present invention is to provide a high-freq...
