Vein viewing system

Abstract

The invention provides a vein viewing system. The vein viewing system comprises a control system (1), visible laser (2), near infrared laser (3), a MEMS (Micro Electro Mechanical System) scanning galvanometer system (4) and an infrared detector (5). Near infrared light is used for carrying out two-dimensional scanning by controlling the MEMS scanning galvanometer system (4); then by being input into the control system (1), an infrared scattered light signal measured by the infrared detector (5) is read into an image input buffering part of the control system (1); the image processing is carried out by an image processing part; a processed image is transmitted to a 2D (two-dimensional) imaging controller (10) to control the projection imaging of the visible laser; and a vein image with the ratio of 1:1 with a real object is projected onto a tested skin surface and the projection of the vein image is coincident with the actual position of the vein on the tested skin surface in the horizontal direction. By the vein viewing system provided by the invention, the accuracy that medical personnel positions the vein is greatly improved, the medical dispute caused by misoperation or repeated operation is reduced, the pain of a patient is reduced and the medical time is shortened.

Description

technical field [0001] The invention relates to a medical device, in particular to a vein viewing system. Background technique [0002] Intravenous injection, venous blood collection, and blood transfusion are one of the important measures for rescuing and treating patients, and they are also a very common medical method. , often hinders the implementation of the venipuncture process under the naked eye. For some patients with inconspicuous veins, such as newborns, children, obese people, and people of certain ethnicities, it is difficult to find the exact location of the vein even for skilled nurses, so it often takes multiple operations The injection is successful, which will increase the pain of the patient. What's more, in some emergency situations, every delay may have serious consequences. Therefore, how to locate the vein quickly and accurately is very important. At present, in the practical operation in the hospital, various methods are also used to try to find t...

Problems solved by technology

[0003] (1) Using tourniquet bandage, which is the most traditional and commonly used method at present, but for the former patients, this method is often ineffective

[0004] (2) Using a vascular ultrasound perspective device, but the operation and use of this instrument is relatively cumbersome, the requirements for equipment and technology are high, the requirements for medical staff are high, and the volume is relatively large, so its application is limited to a certain extent
