A Vein Imaging System Based on Hyperspectral Imaging

Abstract

The invention relates to a vein imaging system based on hyperspectral imaging. The vein imaging system based on hyperspectral imaging comprises a near-infrared light source module, an image acquisition module, an image processing module and an in-situ projecting module. Under a natural light environment, the near-infrared light source module scatters two-waveband near-infrared light evenly to the surface of an object to be detected, the image acquisition module acquires multispectral vein images automatically and extracts and submits the multispectral vein images to the image processing module for processing, and virtual vein images are projected to the surface of the object to be detected in situ by a projector. The vein imaging system based on hyperspectral imaging is capable of acquiring the two-waveband vein images simultaneously based on hyperspectral imaging, and blood vessel information is highlighted after image processing to achieve in-situ projection of virtual images, so that medical personnel can be assisted in vein positioning and puncture guidance.

Description

technical field [0001] The invention relates to an auxiliary medical device, in particular to a vein imaging system and method based on hyperspectral imaging. Background technique [0002] Intravenous injection is the basic method of clinical medical treatment. In some emergency situations, such as massive bleeding, renal failure, hypotension, shock and cardiac arrest, it is urgent for medical personnel to locate the vein quickly and accurately. However, even experienced phlebotomists and doctors have difficulties in finding veins, especially for people with unclear blood vessels such as obesity, edema, the elderly and children. Relevant data show that among the 500 million intravenous injections in the world every year, the number of first-time puncture failures reaches 14 million, and even 15,000 patients will suffer from the pain caused by more than 4 punctures every day. Therefore, medical personnel urgently need a kind of vein imaging system that can assist puncture. ...

Problems solved by technology

This type of imager can improve the effect of vein visualization, but this method usually uses dual light sources or projectors instead of dual light sources, and the images need to be acquired in time, and the clinical real-time performance needs to be tested

At the same time, the fusion processing method of the two images tends to be simpler, which is not conducive to the final imaging of the veins.
