[0002] In modern clinical medicine, simple respirators are used as temporary alternatives to artificial ventilation for those who cannot breathe independently. They have been widely used in various emergency resuscitations and occupy a very important position in modern medicine. In the latest version of the "Medical Device Classification Catalog", the epidemic prevention and emergency equipment resuscitators in sub-catalog 08 "Respiratory, Anesthesia and Emergency Equipment" include: serial number 04 cardiopulmonary resuscitation equipment, serial number 05 artificial resuscitator (simple respirator), and serial number 06 pneumatic emergency resuscitation device. Among them, 04 and 05 are passive devices that rely on manual squeezing of the balloon to work, and 06 relies on pressure gas cylinders or centralized gas supply. There is no active power resuscitator. Even if the respiratory equipment is active, it cannot be used in epidemic prevention and emergency scenarios. The core reason is: due to the unreasonable structural design of the ventilator and the huge size of the air pump, it is not convenient to apply it to portable emergency breathing equipment; therefore, in order to solve the above problems, it is necessary to design a physiological feedback power respirator for epidemic prevention and emergency resuscitation.

The traditional respirator that replaces the manual squeezing balloon is replaced, and the purpose of respiratory resuscitation for patients can be completed with high quality and safety in combination with multiple parameters such as gas flow, respiratory impedance, and respiratory quality related to breathing;

[0023] like Figure 2-4 As shown, the specific structure of the respiratory flow detection device is as follows: the respiratory flow detection device includes an output respiratory flow meter 3 and an input respiratory flow meter 4 arranged in parallel, the air inlet of the output respiratory flow meter 3 is connected to the air outlet of the brushless DC high-speed fan 2, the output air pipe 9 and the oxygen input pipe 8 are respectively connected to the two side walls of the output respiratory flow meter 3, and the input air pipe 10 and the exhalation outlet pipe 11 are respectively connected to the two side walls of the input respiratory flow meter 4.

[0024] like Figure 1-4As shown, the specific structure of the information acquisition device is as follows: the information acquisition device includes two groups of information acquisition components, the two groups of information acquisition components are connected to the integrated circuit board 1 through the wire 12 respectively, and a detection loop is formed when the two groups of information acquisition components are in contact with the patient's skin; specifically, the information acquisition component includes a respiratory impedance signal electrode sheet 5 and a PPG test module 6, the respiratory impedance signal electrode sheet 5 is provided with a waist-shaped groove in the middle of the board surface and the PPG test module 6 is installed in the waist-shaped groove, and the respiratory impedance signal electrode sheet 5 and the PPG test module 6 are connected to the integrated circuit board 1 through the wire 12; wherein, the PPG test module 6 is an outsourced part, which is composed of a light emitter (light emitting diode, LED), a light sensor (photodiode, PD), an analog front end (AFE) chip and an accelerometer; accurate breathing principle: the principle of measuring breathing is actually realized by built-in sensors and algorithms. Usually, an optical heart rate sensor and an acceleration sensor are built-in, and these sensors and algorithms can be used to measure breathing; first, the optical heart rate sensor can detect the flow of blood by irradiating the skin with light and receiving reflected light. When a person breathes, the movement of the chest and abdomen will cause changes in blood flow, and these changes can be detected by the optical heart rate sensor, and then the breathing situation can be inferred. By analyzing the signal waveform and frequency of the reflected light, the frequency and amplitude of the breathing movement can be obtained, thereby realizing the monitoring of breathing; secondly, the accelerometer can obtain the human body's breathing signal by detecting the floating movement of the body. When a person breathes, there will be slight movements in the chest and abdomen, which will cause slight vibrations. These vibration signals can be detected by the accelerometer, and the frequency and amplitude of breathing can be obtained through algorithm processing.

[0025] In actual use, the data of the optical heart rate sensor and the acceleration sensor are usually fused and processed, and a composite algorithm is used to improve the accuracy and stability of the measurement. At the same time, personalized corrections are also performed based on the user's physical characteristics and floating state to improve the accuracy of the measurement.

[0026] In general, the principle of monitoring breathing quality is to use the built-in optical heart rate sensor and accelerometer to detect changes in blood flow and body floating, and to obtain the frequency and amplitude of breathing through algorithm processing. The accuracy and stability of measurement can be improved through composite algorithms and personalized corrections. In addition, the accuracy of breathing measurement is also related to factors such as the wearing position and ambient light. When wearing it, you should try to keep it close to the chest skin to avoid uneven light exposure, which will affect the accuracy of the measurement.
