Blood oxygen saturation detection device based on wearable device

Abstract

The invention discloses a wearable device based blood oxygen saturation degree detection device which comprises a blood oxygen sensor, an integrated analog front end, a mixed signal microcontroller, a Bluetooth module, a display device, a power supply management module, a solar cell, an input device and an indicating lamp. The blood oxygen sensor is arranged on the back side of the wearable device and is in contact with the skin. The blood oxygen sensor is connected with the integrated analog front end, the integrated analog front end is connected with the mixed signal microcontroller, and the Bluetooth module is connected with the mixed signal microcontroller and an external network respectively. The power supply management module and the solar cell are connected and used for detecting power supply of relevant parts in the device. the input device is used for starting a blood oxygen saturation degree detection function of the wearable device, and the indicating lamp is used for displaying the blood oxygen saturation degree detection function state of the wearable device. The wearable device based blood oxygen saturation degree detection device is small in size, accurate in result and very low in power consumption, can utilize solar energy to achieve charging and facilitates anytime anywhere blood oxygen saturation degree monitoring of outdoor exercises and hypoxic diseases.

Description

technical field [0001] The invention relates to the research field of a vital sign parameter detection device, in particular to a blood oxygen saturation detection device based on a wearable device. Background technique [0002] Oxygen in the air enters the blood after being exchanged in the lungs of the human body, and is combined with hemoglobin to supply to the whole body to maintain the normal metabolism of cells. Blood oxygen saturation (SpO2) is used to reflect the oxygen level in the blood, and blood oxygen saturation refers to the percentage of the capacity of oxygenated hemoglobin (HbO2) in the blood to the total hemoglobin (Hb) capacity. Under normal circumstances, the blood oxygen saturation of the human body is maintained at 98%, generally not lower than 94%. If the blood oxygen saturation is too low, it indicates that the tissues cannot get enough oxygen, or cannot make full use of oxygen, causing tissue Abnormal changes in the metabolism, function, and even mo...

Problems solved by technology

[0003] At present, the blood oxygen saturation detection function is commonly used in various monitors or monitors, providing an objective vital sign parameter for monitoring, rescue, and health evaluation. However, most of the blood oxygen saturation detection devices that are common on the market Using the transmissive blood oxygen saturation detection method, using finger cots or finger clips to complete the detection, not only is it bulky, inconvenient to operate, and poor in comfort, it will also cause tension during the detection and bring psychological pressure to the tester, resulting in a negative result. distortion

In addition, the power supply of existing blood oxygen saturation detection devices is almost all powered by batteries or recharged by power sources. This power supply method greatly limits the usable time, and cannot meet the growing demand for portable devices, nor can it meet the needs of users at any time. Wearable requirements for real-time testing according to the needs of the tester anywhere
