Problems solved by technology
The higher the pumping speed of the air pump, the faster the brush speed, and the shorter the working life of the air pump
The air pump with a brushless motor will greatly improve its working life, but the price will be much higher than that of an air pump with a brush motor. In addition, the current gas measurement device in the industry adopts a method of setting the pumping rate fixedly. Especially for gas measurement application scenarios, it will lead to increased system power consumption and low work efficiency. In summary, there is still a lack of an optimized gas pump usage method in the industry, which can not only improve the life of the gas pump, but also provide long-term reliability of the system. , reducing system power consumption and hardware cost

The invention relates to the technical field of medical gas detection, in particular to a gas detection control method and device. The invention provides a gas detection control method by which the pumping speed of a gas pump can be self-adaptively adjusted according to the frequency change of respiratory wave signals. On the premise of meeting the measurement precision demand of the system, the pumping speed of the gas pump can be reduced as much as possible, the working life of the gas pump can be effectively prolonged, the long-time reliability of the system can be provided, and the power consumption and hardware cost of the system can also be lowered.
Description
technical field [0001] The invention relates to the technical field of medical gas detection, in particular to a control method and device for gas detection. Background technique [0002] The detection methods of respiratory gas concentration in the medical field can generally be divided into two types: mainstream and bypass. Mainstream gas concentration measurement devices are usually placed in the breathing circuit close to the patient's mouth or trachea to directly measure the gas concentration in the respiratory airflow. The sidestream gas concentration measurement device uses an air pump (usually a diaphragm pump) to draw the airflow from the breathing circuit to the position where the gas concentration measurement device is located through a thin tube about 2 meters long. The advantage of the mainstream gas concentration measurement device is that it can provide real-time intermediate processing data information including gas concentration of the gas to be measured in...
