Description

Technical Field

[0001] The utility model relates to the technical field of blood oxygen medical sensors, in particular to a blood oxygen medical sensor. Background Art

[0002] Blood oxygen saturation (SaO2) is the percentage of oxygen-bound oxyhemoglobin (HbO2) in the blood compared to the total available hemoglobin (Hb) capacity. This refers to the concentration of oxygen in the blood and is a key physiological parameter of the respiratory circulation. Functional oxygen saturation, which differs from the percentage of oxyhemoglobin, is the ratio of HbO2 concentration to HbO2+Hb concentration.

[0003] There are many instruments for detecting blood oxygen saturation, most of which require use with sensors to convert optical signals into electrical signals. For ease of use, existing sensor probes are mostly disposable, with only the probe head wrapped around the finger, and then connected to the blood oxygen medical instrument through a plug for use. However, once the sensor probe line is fixed, it is easy to cause the line to be pulled or the plug connection to loosen when the finger shakes drastically. Most patients find it difficult to keep their fingers in the same position during the test.

[0004] Therefore, it is necessary to design a blood oxygen medical sensor to solve the above problems. Utility Model Content
