The use of a vein finder would help the nurse and phlebotomist to easily locate the vein, preventing venipuncture failure, pre-analytical error in the specimen collection and even more discomfort and pain to the patient.

Locating the vein is not easy, there are some factors that affect patients’ veins visibility such as variation on the skin of the young children (especially infants), obesity and dehydrated patients. In this case, we need a tool to help the nurse or doctor to find the vein and complete the treatment without any difficulty. Moreover, failure in venipuncture may cause thrombosis of the vein, hematoma, or even nerve injury involving the lateral antebrachial cutaneous nerve, which can lead to the so-called “causalgia” or complex regional pain syndrome.

Normally, there are two technology applied to machine which used to find the vein. One is laser technology, another is infrared technology. Both of them has pros and cons. The most famous application brand of laser technology is AccuVein, laser can penetrate the surface of the skin and show the dynamics of deep blood vessels, but maybe harm the eyes` of patients or nurses. Most of brands adopt infrared technology because of safe and stable.

Vein finder is a medical device based on the principle of the different light absorption rate between blood and surrounding tissue. In that case, this device can show veins in real time and  the medical staff as nurses and doctors can locate the vein and do all kinds of procedure more efficiently and more easily.

The Advantages of ZD Vein Viewer

v Effects aspect

full-color imaging, it can arbitrarily adjust the color of blood vessel images and background, increase contrast, and achieve accurate imaging effects and high image clarity.

v Safety aspect

It adopts safe medical cold light source, without laser, which can effectively prevent the instrument from harming the eyes of users and patients.

v Performance aspect

It adopts advanced patented technology and self-developed new image acquisition auxiliary system, which makes the image more clear and accurate. Even the blood vessel images of people who have difficulty in needle sticking can be clearly displayed.

v Practical aspects

The mainframe and support adopt dual power supply structure, which can work continuously for more than 13 hours. The instrument has no limitation of light conditions, it is in small size, light weight, flexible and convenient to carry.

The Application of ZD Vein Viewer

Unclear positioning of blood vessels not only easily causes repeated puncture, causing complications such as phlebitis and hematoma, but also causes doctor-patient disputes.

ZD Vein Viewer is useful for children, elderly patients, patients suffering from edema symptoms (such as kidney disease, cancer, liver cirrhosis, diabetes patients, etc.), obese and overweight people, people with dark skin, anemia, low blood pressure or blood loss, and people who have peripheral vasoconstriction symptoms and other problems so medical staff find it difficult to accurately locate the blood vessels on the back of the hand in a short time.
