Oximeter

Abstract

The invention discloses an oximeter which comprises a blood oxygen data acquisition unit, a motion data detecting unit and a control processing unit, wherein the control processing unit comprises a model selection module; the blood oxygen data acquisition unit is used for acquiring blood oxygen data according to the indication of the control processing unit and sending acquired blood oxygen data to the control processing unit; the motion data detecting unit is used for acquiring motion data and sending detected motion data to the model selection module and the control processing unit; the model selection module is used for selecting corresponding blood oxygen data processing models based on motion data detected by the motion data detecting unit and sending selection results to the control processing unit; in addition, the control processing unit is used for obtaining blood oxygen values based on the selected blood oxygen data processing models and blood oxygen data acquired by the blood oxygen data acquisition unit. The oximeter can achieve higher accuracy in both stationary state and motion state.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, and in particular relates to a blood oxygen measuring instrument. Background technique [0002] With the improvement of living standards, people pay more and more attention to the health of themselves and their families, and blood oxygen content is an important indicator of human health status. Being able to know the value of blood oxygen content at any time is of great importance to people's daily health care. Significance. To this end, technicians have developed a blood oxygen measuring instrument suitable for ordinary family members, which calculates the ratio of the absorbance change rate of red light and infrared light at different wavelengths of human body peripheral parts such as fingers or earlobes to calculate the peripheral blood oxygen meter. Tissue arterial oxygen saturation. [0003] However, this kind of oximeter usually only has high measurement accuracy and precision w...

Problems solved by technology

[0003] However, this kind of oximeter usually only has high measurement accuracy and precision when people are in a static state. When people are in a state of motion, the measurement accuracy will be reduced due to the shaking or shaking of the user.

This is because: on the one hand, the shaking or swinging of the measurement site will change the path of light in the transmission process and affect the accuracy of the measurement results; on the other hand, movement will affect the venous blood vessel volume and venous oxygen content, thus affecting the extraction of arterial signals
