Chinese patent CN101799862 discloses a portable device for collecting and identifying biometric features of veins on the back of the hand. In this patent, a ring-shaped near-infrared LED array is used to illuminate the collection area on the back of the hand. Through experimental verification, this patent cannot obtain uniform illumination in the collection area, which affects Contrast quality of acquired images
Chinese patent CN102379699 discloses a method for improving the clarity of body surface veins and a venous vessel puncture observer. This method uses a switch controller and a time interval controller that alternately emit light from three-color LED light sources. The disadvantage of this patent is that the structure more complex and costly

Abstract

The invention relates to a collecting and displaying device for hand vein images, which consists of a near infrared image collecting module, a near infrared lighting module, an image processing module and a visible light projecting and displaying module. A medical device based on an optical instrument is formed by integrating a near infrared reflective image collecting system with a visible light projecting and displaying system effectively. The collecting and displaying device for hand vein images can be widely applied to medical means such as injection, blood drawing and blood transfusion for hand veins of human bodies.

Description

technical field [0001] The invention belongs to the field of optical instruments, and in particular relates to a device for collecting and displaying vein images on the back of the hand. Background technique [0002] In medicine, the purpose of curing diseases is achieved by injecting into human veins, drawing blood, transfusion and other medical means. In some patients, due to thick fat, dark skin, excessive blood loss and other reasons, blood vessels cannot be clearly displayed, resulting in medical obstacles such as "missed needle" and "puncture failure", which brings inconvenience to doctors and patients. At present, in the process of clinical diagnosis and treatment, it is a very critical task to quickly and accurately locate the patient's venous blood vessels in medical work. [0003] The reproduction process of the veins on the back of the hand requires the cooperation of various modules to complete. First of all, the acquisition of vein images on the back of the ha...
