Technical Field

[0001] The utility model relates to the technical field of vein detectors, in particular to a vein detector. Background Art

[0002] Veins refer to blood vessels that originate from capillaries and transport blood from organs and tissues throughout the body back to the heart. The walls of veins are thin, the cavities are large, the elasticity is low, the internal pressure is low, and the blood flow is slow. At present, for infants, the elderly, obese patients, patients undergoing multiple chemotherapy, etc., because their blood vessels are poorly elastic, their blood vessels are severely collapsed, their blood volume is reduced, or their blood vessels are relatively small, it is difficult to identify the veins when performing intravenous injections, punctures, or drawing blood for these patients. It is very easy for doctors and nurses to have inaccurate experience in intravenous injections, resulting in multiple injections, aggravating the mental fear and physical pain of patients, especially increasing the tension and pain of infants and the elderly, and even causing disputes between doctors and patients, resulting in other adverse events. Therefore, how to provide a vein detector that can assist medical staff in quickly and accurately finding the location of the vein that can be injected is a problem that technicians in this field urgently need to solve.
