Embodiment Construction

[0064] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0065] An example of the sensor of the present invention is: the main components of the sensor include a flexible support substrate 101, a light-emitting diode 107, and the light-emitting diode can emit near-infrared light of 5 wavelengths (690nm, 730nm, 770nm, 810nm, 850nm, 760nm); two A receiving photodiode 108, 109; a signal line 104 for connecting the light emitting diode 107, the photodiodes 108 / 109 with the signal processing device.

[0066] The sensor is pasted on the surface 102 of the tissue to be detected 103 through the double-sided tape on the back of the flexible support subst...

Abstract

The invention relates to an automatic judging system for a monitored part of the oxyhemoglobin saturation of the tissue. The judgment for the position of a sensor is obtained, so that a correspondingoxyhemoglobin saturation calculation model can be selected during the calculation for the oxyhemoglobin saturation, and the accurate oxyhemoglobin saturation result is obtained. According to the system, the original light intensity data collected by the sensor is converted to obtain more useful intermediate parameters, then through a random forest classification model, the mapping relation betweenthe intermediate parameters and the category of the detected part is established, thus the classification evaluation for the detected part is realized, the manual intervention is reduced, and the measurement precision is improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a method, a measuring device and a medical device for measuring the blood oxygen saturation of local tissues of a human body. Background technique [0002] Local tissue oxygen saturation is the percentage of the capacity of oxygen-bound oxyhemoglobin (HbO2) in the blood to the total local bindable hemoglobin (Hb, hemoglobin) capacity, that is, the concentration of blood oxygen in the blood. Important physiological parameters, important body parameters that need to be monitored during surgery and in specific care situations. [0003] At present, the most widely used device for blood oxygen saturation detection at home and abroad is the pulse oximeter, which is generally used in the fingertip and earlobe. In many cases, arterial blood oxygen saturation cannot accurately reflect the oxygenation of local tissues. For example, when local tissue is difficult to utilize oxygen,...
