Abstract

The invention discloses a venous visualizer and a visualizing method. The visualizer comprises an optical system for visualizing deep veins, and a liquid crystal display system, wherein the optical system comprises a near infrared light source and a venous image acquisition unit; the venous image acquisition unit is used for dividing reflected light into two paths so as to separate near infrared light from visible light; the near infrared light comprises information of deep veins (3 millimeters); after being subjected to image enhancement, the near infrared light is subjected to image fusion with a visible light image, and a fused image is displayed on the liquid crystal display screen for a doctor to refer to during venipuncture. Due to the adoption of a dynamic frame-by-frame image fusion algorithm, a venous enhanced image obtained by near infrared light activation can be overlapped on an ordinary image in real time, and an entire venipuncture process can be displayed completely on the liquid crystal screen.

Description

[0001] technical field [0002] The invention relates to the field of medical devices, and more specifically, to a vein developing device and a developing method. Background technique [0003] 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. [0004] In recent years, an instrument that helps doctors locate subcutaneous veins has appeared on the market—vein imaging instrument, which utilizes the characteristics of deep tissue penetration depth of near-infrared and strong absorption of near-infrared light by veins. The veins are visualize...
