Abstract

The invention relates to a vein dynamic characteristic analysis device based on a near-infrared spectrum technique and an analysis method thereof. The vein dynamic characteristic analysis device comprises a static table, a near-infrared camera and two reflecting light sources located above the static table, wherein the reflecting light sources are symmetrically arranged by taking a longitudinal axis of the static table as the axis; a near-infrared transmission light source is arranged right under the static table; the near-infrared camera is arranged right above the static table; the near-infrared camera is connected with a computer and is used for sending a detected image to a data processing unit in the computer; the vein dynamic characteristic analysis is realized through a preset algorithm. According to the invention, the near-infrared reflection and transmission light sources are combined, the suitable optical path design is adopted, a noisy point problem caused by a single transmission light source is effectively solved, and the image contrast and the imaging quality are increased. The vein dynamic characteristic analysis device is safe and non-invasive, low in cost and good in instantaneity. The image enhancing processing is combined with the algorithm, such as frame difference, so that the accurate calculation for the dynamic characteristics can be realized.

Description

technical field

[0001] The invention belongs to medical and scientific experiment auxiliary devices, and specifically relates to an analysis device and analysis method for the dynamic characteristics of human and mammalian veins and blood vessels by using near-infrared spectrum. Background technique

[0002] Studies have shown that blood flow parameters can well reflect the vascular function and physiological status of individual animals, and can play a very positive role in the prevention, early diagnosis and treatment of many diseases. Especially in the early stage of many diseases, the individual has not yet found obvious symptoms, but at this time blood flow parameters such as vascular resistance and vascular viscosity have actually changed. Therefore, timely, convenient, and accurate monitoring of hemodynamic parameters is of great significance to the assessment of animal health and the prevention of epidemics, and it also shifts medical diagnosis from vascular morpholo...
