The beneficial effects of the utility model are as follows:

In the present application, the portable blood oximeter with networking function is based on Bluetooth transmission, can transmit measurement data to nearby electronic products, can quickly receive data and timely feedback data, and is convenient for subsequent monitoring.

Portable oximeters currently on the market can measure pulse and blood oxygen saturation. Portable oximeters are generally composed of a microprocessor, a memory and two LED light-emitting devices, one of which is a red light LED and the other is an infrared light LED. When measuring, the oximeter will detect two different wavelengths of light, emit detection light to penetrate the skin and reach the blood, and calculate the concentration of oxygenated blood and non-oxygenated blood in the blood by absorbing light, and finally measure the blood oxygen saturation. However, the traditional oximeter is currently limited to displaying data on the display screen it carries, and cannot provide data analysis and data feedback in time. Even the currently popular sports bracelets, due to skin color, ambient light and exercise, everything will affect the accuracy of blood oxygen saturation, and its accuracy is not as good as that of portable oximeters. The portable oximeter with networking function is based on Bluetooth transmission, and can transmit measurement data to the portable oximeter with networking function of electronic products, which can quickly receive data, analyze data, and feedback data. Its feedback form is easy to understand, providing certain guarantees for health monitoring of the elderly.

When in use, the detection effect is achieved by pressing the contact surface with a finger. After the test, the sensitivity is high and the real-time transmission is stable. When there is no finger pressing on the blood oxygen detection circuit 200, the Bluetooth transmission and the data displayed on the display are zero. When the human tissue is placed on the acquisition module, the data can be seen on the device through Bluetooth after a short period of collection, and it is displayed in real time on Bluetooth.

The Bluetooth transmission function can provide a more user-friendly interface and interaction method. Users can connect the oximeter and mobile devices through simple operations and adjust the settings according to their needs. This interactivity can make the use of oximeters more intelligent, convenient and personalized.

Considering factors such as power consumption, communication range and data transmission rate, a low-power Bluetooth module such as Bluetooth Low Energy (BLE) is selected. According to the selected Bluetooth module specifications, the corresponding circuit board or module is designed and manufactured to connect with the circuit board of the traditional oximeter.
