Problems solved by technology
[0003] At present, the devices used to detect blood oxygen saturation are mainly limited to places where the distribution of capillaries is relatively concentrated, such as the extremities of the limbs, and cannot achieve long-term dynamic detection. There are even fewer blood oxygen tests, and the clinical detection of blood oxygen in these parts still refers to the "blind test" of blood oxygen by sleeve or arterial indwelling needle

Abstract
The invention relates to a flexible device for deep-layer blood oxygen detection and a making method thereof. The device comprises a power source assembly, a photoelectric detection assembly and a flexible substrate. The power source assembly comprises a vertical-cavity surface-emitting laser (VCSEL), and the vertical-cavity surface-emitting laser is used for emitting light waves with different center wavelengths or different spectra to a detected object; the photoelectric detection assembly receives photosignals after light wave reflection and conducts photoelectric conversion, and afterwards, signal processing is conducted to obtain blood oxygen detection signals; the flexible substrate is made from a flexible material and used for packaging the power source assembly and the photoelectric detection assembly. According to the embodiment of the invention, blood oxygen detection at the deep part can be achieved; meanwhile, by utilizing the flexible substrate for packaging the assemblies, the device can achieve large-degree extension and deformation and conveniently fit the surface of the skin, detection of the blood oxygen saturation degree of deep-layer artery blood vessels such ascarotid arteries and femoral arteries is achieved, wearing can be also facilitated, and high-reliability real-time detection is achieved.
Description
technical field [0001] The present disclosure relates to the technical field of electronic devices, in particular to a flexible device for deep blood oxygen detection and a manufacturing method thereof, which can be used for deep blood oxygen detection. Background technique [0002] Blood oxygen saturation (SpO 2 ) refers to the capacity of oxygenated hemoglobin in blood (HbO 2 ) as a percentage of the total hemoglobin capacity (Hb) that can be combined is an important parameter reflecting the oxygen content of human blood, a physiological parameter that measures the oxygen-carrying capacity of human blood, and has important reference value in the fields of clinical medical testing and medical monitoring. While functional oxygen saturation (such as arterial oxygen saturation SaO 2 ) for HbO 2 Concentration and HbO 2 The ratio to the Hb concentration is different from the percentage of oxyhemoglobin. Many clinical diseases will cause a lack of oxygen supply, which will d...
