Abstract

The invention discloses a near-infrared waveband LED (light emitting diode) light source imaging system which comprises an optical system and a liquid crystal display system, wherein the optical system is used for developing a relatively deep vein; the optical system comprises a near-infrared light source and an image acquirer; the image acquirer is used for splitting reflection light into two paths to separate near-infrared light and visible light; the near-infrared reflection light contains information of the vein in a relatively deep position (greater than 3 mm); after image enhancement, an image of the vein can be subjected to image fusion with an image of the visible light, and the images can be displayed on a liquid crystal display screen and are referred by doctors when venipuncture is implemented. By using a dynamic frame-by-frame image fusion algorithm, a vein enhancement image obtained through near-infrared excitation can be overlapped with a common image in real time, and the whole venipuncture process can be completely displayed on the liquid crystal screen.

Description

technical field [0001] The application belongs to the technical field of medical imaging equipment, and in particular, relates to an image imaging system with near-infrared band LED light sources. Background technique [0002] In the medical field, blood tests, intravenous infusions, blood transfusions, etc. all require venipuncture. However, venipuncture is more difficult in people with darker skin and deeper, thinner veins. The decline in the success rate of the first venipuncture has caused burden and damage to the patient's psychology and the blood vessels themselves; in addition, in some special cases, the success rate of venipuncture directly affects the rescue of critically ill and emergency patients. [0003] In recent years, a device to help doctors locate subcutaneous veins has appeared on the market. It utilizes the characteristics of deep tissue penetration depth of near-infrared and strong absorption of near-infrared light by veins to develop veins. The repres...
