Problems solved by technology

The method adopted by the traditional technology is relatively complicated. It needs to calculate and obtain four indications such as amplitude, roundness, flatness and kurtosis, and then observe the long-term trend. When two or more indication trends are found to occur airflow limitation is considered to occur when

Embodiment 1

[0030] Such as figure 1 As shown, the present invention provides a ventilator inspiration trigger method, the method comprising:

[0031] Step 1: Obtain the airflow data of the user during the inhalation phase; specifically, such as figure 2 As shown, the flow sensor is used to collect the respiratory airflow data of the user on the ventilator end. Although the respiratory airflow of different users is different, the respiratory airflow flow rate, the total amount of gas inhaled or exhaled are different, but for the same user's inhaled airflow at the same time The total amount of breath and exhaled gas is basically equal, so the average value of the user's respiratory air flow can generally be used as an inhalation trigger point, and the part higher than the average respiratory air flow is used as the air flow data of the inhalation phase in the present invention.

[0032] Step 2: Calculate the inspiratory time (T) and obtain the time point of peak inspiratory flow (t 0 ) a...

Embodiment 2

[0045] In this embodiment, an airflow limitation detection device is provided, and the airflow limitation detection device includes: an acquisition module, used to acquire the airflow data of the user under the action of positive pressure ventilation equipment; an analysis module, used to calculate the inspiratory time, And obtain the peak inspiratory flow time point (t0) and the flow average value (M) in the inspiratory phase; judging module: used to judge when the flow peak time point (t0) is less than the first preset time point (t1) or greater than the second At the preset time point (t2), and the user's average flow deviation (N) between the first preset time point and the second preset time point is smaller than the first predetermined threshold, it is determined that the airflow is limited.

Embodiment 3

[0047] In this embodiment, there is also provided a computer-readable storage medium on which a computer program is stored, wherein the computer program is executed by a processor in the following steps: acquiring the airflow data of the user under the action of positive pressure ventilation equipment ;Calculate the inspiratory time, and obtain the peak inspiratory flow time point (t0) and the flow average (M) during the inspiratory phase; determine when the flow peak time point (t0) is less than the first preset time point (t1) or greater than the first preset time point (t1) At two preset time points (t2), and the user's average flow deviation (N) between the first preset time point and the second preset time point is smaller than a first predetermined threshold, it is determined that the airflow is limited.

Abstract

The invention provides an airflow limitation detection method. The airflow limitation detection method comprises the steps of 1, obtaining airflow data of a user in an inspiration stage; 2, calculating the inspiration time, and obtaining an inspiration flow peak time point and a flow mean value of an inspiration stage; and 3, when the flow peak time point is smaller than a first preset time pointor larger than a second preset time point, and the flow mean deviation of the user between the first preset time point and the second preset time point is smaller than a first threshold value, judgingthat airflow is limited. The airflow limitation detection method can effectively detect airflow limitation when a user uses a respirator, provides powerful help for further ventilation treatment, caneliminate other apnea, gasp, cough and other events, further improves the airflow limitation detection accuracy, and improves the user experience, so the comfort level of ventilation treatment is improved, the use compliance of a user is improved, and the ventilation treatment effect of the respirator is improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a method, device, storage medium and computer equipment for detecting airflow limitation. Background technique [0002] COPD is a lung disease characterized by persistent obstruction of airflow from the lungs. COPD has a high morbidity and mortality rate. According to the Global Burden of Disease Research Report, there were 251 million cases of COPD in the world in 2016, with 3 million deaths, ranking third among the causes of death in the world. The definition of COPD is based on airflow limitation, but patients usually go to the hospital because of certain symptoms such as cough, sputum, and wheezing that affect daily life, or some chronic symptoms persist, or because of an acute exacerbation. See a doctor. The progression of COPD is slow, and the early symptoms are hidden. Once obvious symptoms appear, most patients are already in the middle and late stages of the ...
