Abstract

The invention discloses a vein vessel recognition system based on a venipuncture robot, which belongs to the technical field of electromechanical integration, and aims at solving the problems that existing venipuncture greatly depends on experience and proficiency of medical staff, and the medical staff is very difficult to accurately conduct venipuncture on special patients. A near-infrared lightsource module is used for providing near-infrared light; wherein the two near-infrared image acquisition modules are used for acquiring near-infrared images of veins respectively and sending the acquired two near-infrared images to the image processing module respectively; and the image processing module is used for performing image processing on the two near-infrared images to obtain a completevein blood vessel upper surface point cloud picture, and displaying the vein blood vessel upper surface point cloud picture in real time. The system has the beneficial effect of improving the venipuncture success rate.

Description

technical field [0001] The invention belongs to the technical field of mechanical and electrical integration. Background technique [0002] Piercing a vein to obtain a blood sample or injecting a drug is one of the most common medical procedures, whether in a large hospital or a small clinic. At present, clinical venipuncture mainly relies on skilled medical personnel, who need special training and a lot of attempts. The commonly used venous puncture method is as follows: tie a tourniquet on the patient, and then let him make a fist to make the venous blood vessel stand out so as to facilitate venipuncture. The success rate of this puncture procedure greatly depends on the experience and proficiency of the medical staff. For patients with dark skin, deep veins, covering injuries, tattoos and hair, especially infants, the elderly, obese and dehydrated patients etc., because it is difficult to locate the venous vessel position accurately, it is very difficult to want to carr...
