Problems solved by technology

In the medical field of disease detection, common medical imaging instruments include ultrasound and X-rays. X-ray imaging equipment also requires a specific installation space. This large-scale equipment is used to detect diseases in deeper parts of the human body. Due to factors such as unclear vein imaging, this type of equipment cannot meet the medical needs of intravenous injection
Although the existing infrared imaging technology is developing rapidly in the medical field, it still has some shortcomings, mainly in that the existing shallow imaging technology only stays at the two-dimensional level, and cannot provide three-dimensional images. Imaging technology only provides medical staff with the specific location of the vein, but not the depth information of the vein vessel

Abstract

The invention discloses a hand vein blood vessel depth detection device based on a binocular principle. The device comprises a near-infrared light source module, an image acquisition module, an imageprocessing module and a shell, the near-infrared light source module, the image acquisition module and the image processing module are all supported on the shell, and the hand skin depth and the handvein blood vessel depth can be measured through near-infrared light short-wave band and long-wave band irradiation.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a hand vein blood vessel depth detection device and detection method based on the binocular principle. Background technique [0002] Vein imaging technology plays an important role in biomedicine and feature recognition. In medical treatment, vein imaging technology has been developed rapidly. Relevant data prove that the success rate of the first two intravenous punctures in children is only 42%, and the success rate of the first intravenous puncture in adults is only 73%. After investigation, the reasons for the failure of intravenous injection are composed of various reasons: the fluid injected intravenously leaked from the puncture site, causing 23%-28% of edema at the puncture site, and 10.87% of the time the puncture failed to see blood. The poor quality of the patient’s veins is caused by many factors, such as poor elasticity of blood vessels, thin blood vessels,...
