Blood oxygen testing method and device and storage medium thereof

Abstract

The invention relates to a blood oxygen testing method and device and a storage medium thereof. The method comprises the following steps of S1, naturally attaching a blood oxygen sensor to a wrist skin and filling the space between the blood oxygen sensor and the wrist skin with a water film in a standard state, and acquiring the reading of the blood oxygen sensor in the standard state as a standard reading Z; S2, in the standard state, pressing and rotating the blood oxygen sensor so that the blood oxygen sensor is sucken to press the wrist skin, and acquiring the reading of the blood oxygensensor in the pressing state as a pressing reading Y; and S3, calculating a difference reading C according to an equation as follows: the difference reading C= the pressing reading Y- the standard reading Z, and calculating a fitting reading N according to an equation as follows: the fitting reading N= the standard reading Z- 2* the difference reading C. The blood oxygen testing method and deviceand the storage medium thereof have the advantage of improving the data accuracy of the blood oxygen sensor.

Description

technical field [0001] The present application relates to the field of blood sample testing, in particular to a blood oxygen testing method, device and storage medium thereof. Background technique [0002] Blood oxygen is the oxygen in the blood. The normal oxygen content of the human body is about 90%. The higher the oxygen content in the blood, the better the human metabolism. If it is too low, the body's oxygen supply will be insufficient. Because all cells in the human body need oxygen, abnormal blood oxygen levels will affect most of the body's functions, so the detection of blood oxygen saturation is very common in clinical medicine, surgery, and intensive care units. [0003] Existing professional blood oxygen detection equipment is usually relatively expensive, so in daily life, people wear some wearable devices integrated with blood oxygen detection functions, such as wristbands. Today's smart wearable devices also adopt multi-light source fusion technology technic...

AI Technical Summary

Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor believes that: when the user wears the wristband, if there is external moisture or sweat between the sensor on the wristband and the skin, when the light passes through the area between the sensor on the wristband and the skin There will be a loss, which has the defect of reducing the detection accuracy
