The expert team of HTSY® independently developed and produced the Color Vein Viewer(QV500). This product employs advanced near-infrared light technology, enabling a clear view of the veins beneath the human skin and assisting doctors in performing operations such as venipuncture. HTSY® has a strong production capacity and its production line also has advantages, so the product quality is good and the price is reasonable.
The Color Vein Viewer provided by HTSY® factory is designed to quickly and accurately locate blood vessels. It employs advanced detection technology and can clearly observe the distribution of blood vessels beneath the skin. It will project clear blood vessel images in real time on the skin surface, allowing blood vessels to be directly seen and located more accurately, which can solve the problem of difficulty in locating blood vessels during venipuncture.
The design of this device conforms to the usage habits of human hands and fits the arc of the hand very well when held. It is light in weight and has an even center of gravity. Even when held and operated by hand for a long time, it is not easy to get tired and feels very comfortable to hold. To suit different usage scenarios, it can also be used in conjunction with a desktop stand and a mobile trolley. The desktop stand can fix the device and is suitable for scenarios such as clinics and wards where movement is not required. The mobile trolley is convenient to move flexibly in scenarios such as emergency rescue sites and operating rooms where movement is required. In this way, the equipment can be used in more places and is suitable for various clinical and nursing scenarios
