Problems solved by technology

The continuous wave (CW) method is the easiest to implement and the most widely used clinically, while the phase modulation (PMS) and time-resolved spectroscopy (TRS) methods are relatively difficult to implement
The inventor found through research that there are still relatively few applications of measuring tissue oxygen content by using near-infrared light

Abstract

The invention discloses NIRS technology based muscle oxygenation detection equipment, which comprises an electrode, a light source, a proximal receiving end, a distal receiving end, a temperature sensor, a microprocessor, and a power supply. The provided NIRS based muscle oxygenation detection equipment has the characteristics of small volume, simple control and stable performance.

Description

technical field [0001] The invention relates to the technical field of biomedical engineering, in particular to a muscle oxygenation detection device based on NIRS technology. Background technique [0002] Studies have shown that hemoglobin is the main carrier of oxygen in tissues, which is composed of oxyhemoglobin (HbO2) and reduced hemoglobin (Hb). Oxygen in tissues basically exists in the form of oxyhemoglobin in capillaries in tissues. Blood oxygen saturation refers to the percentage of HbO2 content in hemoglobin (that is, the sum of HbO2 and Hb concentrations). As the aerobic metabolism of the human body changes, blood oxygen saturation will change. [0003] The oxygen saturation of the tissue is the weighted average of the oxygen saturation of blood in the arterioles, venules and capillaries in the measured tissue; because the flow rate of venule blood is relatively slow, it plays a major role in the blood oxygen saturation status. Tissue oxygen saturation can refle...
