Ventilation treatment device and control method thereof

Abstract

The invention provides a ventilation treatment device and a control method thereof. The ventilation treatment device comprises a body, a breathing pipeline, a patient interface, an oxygen supply module, an oxygen proportional valve and a control module; the first end of the breathing pipeline is communicated with the output end of the body; the second end of the breathing pipeline is connected with the patient interface, the oxygen supply module is connected with the body through the oxygen proportional valve, and the control module is used for detecting output parameters of the body, controlling the oxygen proportion valve to be opened according to the preset opening when it is determined that the body is in the preset state according to the output parameters and meanwhile controlling a fan of the body to be operated at the preset rotating speed. According to feedback of the output parameter output by the body, the patient inhaling and exhaling flow can be determined, the opening degree of the oxygen proportional valve and the rotating speed of the fan of the body are adjusted correspondingly, the corresponding patient breathing flow or pressure airflow is delivered to the patient, the patient comfortably receives oxygen of the constant concentration, and the user breathing experience is improved.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a ventilation therapy device and a control method for the ventilation therapy device. Background technique [0002] In modern clinical medicine, ventilation therapy equipment occupies a very important position in the field of modern medicine. Ventilation therapy equipment is a vital medical treatment that can prevent and treat respiratory failure, reduce complications, and save and prolong the life of patients. A device that mixes pure oxygen with air and delivers it to a patient. [0003] At present, common ventilation therapy equipment is usually divided into two types. The first type of ventilation therapy equipment is a wearable breathing mask, which can form a closed space at the patient end and supply air to the closed space for the patient to breathe. , the excess gas can be discharged from the exhaust hole on the mask, and the patient can adjust the flow rate of pure oxy...
