Embodiment Construction

[0036] The present invention first requires that the distance d from the light source to the detector on the sensor be properly determined according to the thickness of the outer tissue of the object to be measured. The thickness of the outer tissue can be obtained by conventional ultrasound techniques. When the outer tissue is thicker, the distance should take a larger value to ensure that the photons can penetrate into the tissue to be tested. According to experience and experimental results, when the thickness of muscle and fat is greater than 15mm, d takes 50mm, otherwise takes 40mm For Xuan. Multi-layer tissue structure and detection methods such as figure 2 shown. exist figure 2 1 is the light source LS1 at a distance of r1 from the optical sensor OPSU, 2 is the light source LS2 at a distance of r2 from the optical sensor OPUS, 3 is the light source LS3 at a distance of r3 from the optical sensor OPUS, 4 is the optical sensor 0PSU, 5 T1 is the first layer of tissue...

Abstract

The invention is a near-infrared nondestructive tissue detecting method for skeletal muscle supersession function's blood transporting parameters, its character: in view of different tested objects (sportsman and non sportsman) and muscle tissue's oxyhemoglobin variation (deta HbO2) as well as reduced hemoglobin variation (deta Hb), it selects proper detecting distance and gives the detecting steps, algorithm and system design which can judge parameters of oxygen supersession ability of muscle tissue. The sensor can be composed of three LEDs and a photoelectric receiver. The whole testing system contains sensor, preamplifying circuit, A / D converter, inserted microprocessor, power supply, liquid crystal and touch screen. It has the advantages of high detecting sensitivity and simple detecting system structure.

Description

technical field [0001] The non-destructive detection method of near-infrared tissue for blood supply parameters of metabolic function of skeletal muscle belongs to the field of spectral technology application and biomedical engineering. Background technique [0002] Using near-infrared dual-wavelength spectroscopy to detect changes in oxygenated (and reduced) hemoglobin in biological tissues is a mature technology at home and abroad. However, the parameters used to evaluate the ability of blood oxygen metabolism during exercise are only the changes in local tissue oxygenated and reduced hemoglobin. Since the ability of blood oxygen metabolism during exercise is not only related to local tissues, but also closely related to the circulatory system, there is no unified The effective parameters comprehensively reflect the ability of blood oxygen metabolism during exercise; there is the influence of outer tissue (outer tissue refers to the tissue covered outside the tissue to be ...
