Embodiment Construction

[0012] Hereinafter, the invention will now be described more fully with reference to the accompanying drawings, in which various embodiments are shown. However, this invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0013] Hereinafter, exemplary embodiments of the present invention will be described in more detail with reference to the accompanying drawings.

[0014] The system can be divided into four parts: reflector, reflector control unit, data processing unit and liquid crystal display unit.

[0015] Reflector: Measuring blood oxygen saturation is based on the principle that deoxygenated hemoglobin and oxyhemoglobin in blood absorb infrared light and red light differently to measure blood oxygen saturation of arterial blood. ...

Abstract

The invention relates to a reflection type oximeter which can be divided into a reflector, a reflector control unit, a data processing unit and an LCD unit. The reflector is a novel reflector in which an infrared light LED, a red light LED and a phototransistor are integrated in a packaging structure, the red light LED and the infrared light LED are made to alternatively emit light through the reflector control unit, one part of light emitted out can be absorbed and transmitted, the other part of the light can be reflected back to the phototransistor, the phototransistor generates current signals, and therefore the oxyhemoglobin saturation is calculated. When the reflection type oximeter is used for measuring, there is no need to clamp one part of a human body, the oximeter only needs to be attached to the surface of the human body and then the absorption spectrum of reflection light is measured, so that the purpose is achieved, and the problem that people feel uncomfortable in the measuring process is completely solved.

Description

technical field [0001] The invention relates to a reflective oximeter and belongs to the detection field. Background technique [0002] Blood oxygen saturation is an important indicator to measure the degree of human health. Although there are already finger-clip oximeters on the market for measuring blood oxygen saturation, the transmission measurement method is generally used. The measurement principle is to use red LEDs, infrared LEDs and phototransistors to clamp translucent parts of the body such as fingertips. , and then measure the absorptance-transmittance ratio of these two kinds of light after passing through the body. This structure has problems such as pressure feeling and blood flow obstruction during measurement. With the improvement of living standards and the requirements of humanity, more and more people not only pay attention to the accuracy of the oximeter, but also pay attention to the comfort. Contents of the invention [0003] Therefore, the presen...
