[0056] Please refer to Figure 1-2 , a medical armband type heart rate and blood oxygen saturation monitoring device in this embodiment, includes:

[0057] An armband 110,

[0058] An optical sensor 120, the detection end of the optical sensor 120 is arranged on the inner side of the armband 110, and the optical sensor is used to measure the heart rate and blood oxygen saturation of the user;

[0059] A data processing module 130, the data processing module 130 is arranged on the armband 110, the data processing module 130 is connected to the optical sensor 120, and the data processing module 130 is used to perform real-time processing and analysis on the data collected by the optical sensor 120;

[0060] A communication module 140, the communication module 140 is arranged on the armband 110, the communication module 140 is connected to the data processing module 130, and the communication module 140 is used to send the monitoring data to an external device;

[0061] A power supply module 150, the power supply module 150 is connected to the optical sensor 120, the data processing module 130 and the communication module 140.

[0062] The heart rate and blood oxygen saturation of the user are measured in real time by the optical sensor 120. The data processing module 130 performs real-time processing and analysis on the monitoring data collected by the optical sensor 120, extracts effective information, and sends the analyzed monitoring data to an external device through the communication module 140. The power supply module 150 provides working power for the optical sensor 120, the data processing module 130 and the communication module 140; The armband 110 type design is adopted, and the optical sensor 120 is fixed on the inner side of the upper arm through the armband 110, which can be applied to most scenarios, and at the same time ensure that the user's heart rate and blood oxygen saturation can still be measured stably during exercise.

[0063] In some embodiments, the heart rate refers to the number of heartbeats per minute of a normal person in a quiet state, also called the resting heart rate. The optical sensor calculates the heart rate by using green light to irradiate the skin and calculating the change of the reflected light by blood flow. The blood oxygen saturation is the percentage of the volume of oxygenated hemoglobin (HbO2) bound to oxygen in the blood to the volume of all bindable hemoglobin (Hb, hemoglobin), that is, the concentration of blood oxygen, which is an important physiological parameter of the respiratory cycle. The optical sensor calculates the blood oxygen saturation by using the difference in absorption of red light and infrared light by oxygenated / deoxygenated hemoglobin when passing through tissues.

[0064] Please refer to Figure 3, in some embodiments, the communication module 140 includes a Bluetooth module 141 and a WiFi module 142. Among them, the communication module 140 adopts the Bluetooth module 141 and the WiFi module 142. Through the Bluetooth module 141, the monitoring device can be Bluetooth-connected to other intelligent devices, such as mobile phones, PADs, etc., and through the WiFi module 142, the monitoring device can be connected to the cloud device to send the collected and analyzed data to the cloud server. In other embodiments, the communication module 140 can also adopt other wireless communication modules 140, such as an NFC module or a ZigBee module, etc.

[0065] Please refer to Figure 3 , in some embodiments, the data processing module 130 further includes a memory 131;

[0066] The data processing module 130 is used to store the monitoring data collected by the optical sensor 120 in the memory 131 and upload the stored monitoring data to the cloud server when there is a network.

[0067] The monitoring device also supports local storage. After the monitoring data is collected by the optical sensor 120, the collected monitoring data is stored in the memory 131. When there is no network, the monitoring device can also be used. When the monitoring device is connected to the network, the data processing module 130 uploads the monitoring data stored in the memory 131 to the cloud server, avoiding the dependence on the intelligent terminal and improving the applicability of the device. Among them, the data processing module 130 is also used to clear the data stored in the memory 131 that has exceeded the preset time to ensure that there is enough storage space in the memory 131 to store the collected monitoring data.

[0068] Please refer to Figure 4 , in some embodiments, the power supply module 150 includes a rechargeable battery 151 and a power management module 152;

[0069] The rechargeable battery 151 is connected to the optical sensor 120, the data processing module 130, and the communication module 140;

[0070] The power management module 152 is connected to the rechargeable battery 151. The power management module 152 is used to monitor and manage the power of the rechargeable battery 151 in real time and start the low-power mode when the power of the rechargeable battery 151 is lower than the preset threshold.

[0071] The power supply module 150 uses a rechargeable battery 151, which supports long-term use. At the same time, the power management module 152 can monitor and manage the power of the rechargeable battery 151 in real time. When the power is lower than the preset threshold, the low-power mode is automatically activated to reduce the power consumption of the rechargeable battery 151. When the power management module detects that the power is lower than the preset threshold, it also sends a reminder signal to the data processing module 130. After receiving the reminder signal sent by the power management module 152, the data processing module 130 sends a charging reminder to the external device through the communication module 140 to remind the user that the battery of the monitoring device needs to be charged. Among them, the rechargeable battery 151 is a lithium-ion battery or a super capacitor. A lithium-ion battery is a secondary battery (rechargeable battery), which mainly works by the movement of lithium ions between the positive and negative electrodes. During the charge and discharge process, Li+ is embedded and de-embedded between the two electrodes: during charging, Li+ is de-embedded from the positive electrode and embedded in the negative electrode through the electrolyte, and the negative electrode is in a lithium-rich state; during discharge, it is the opposite. It has the advantages of high energy density, long cycle life, and low self-discharge rate. A super capacitor (also known as an electrochemical capacitor or supercapacitor) is an energy storage device between a traditional capacitor and a battery, with characteristics such as ultra-high power density, fast charge and discharge, and extremely long cycle life. In other embodiments, the rechargeable battery 151 can also adopt other forms of rechargeable batteries 151.

[0072] In some embodiments, a warning module is further included. The warning module is connected to the data processing module 130. When the data processing module 130 analyzes the monitoring data collected by the optical sensor 120 and detects an abnormal situation, such as a too fast heart rate or too low blood oxygen saturation, it is reminded through the warning module; when the power is too low, it can also be reminded through the warning module. Among them, the warning module can be a vibrator, a speaker, a display screen, or an indicator light, etc.

[0073] In some embodiments, a cushion is provided on the inner side of the armband 110. By providing a soft cushion on the inner side of the armband 110, the wearing comfort of the user can be further improved, which is suitable for long-term use.

[0074] In some embodiments, the data processing module 130 is further configured to analyze the user's physical condition based on the monitoring data collected by the optical sensor 120, and adjust the sampling frequency of the optical sensor 120 according to the user's physical condition.
