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.

Our body is having blood that circulates throughout the body. It is the main part of our circulatory system. It carries hemoglobin, which is the only provider of oxygen to every cell of the body. But, due to various incidents, our body loses blood. We may face the accident, get an injury or have the low percentage of hemoglobin count in the body. In all these cases, transfusion plays a very important part. There are certain steps that both patients and doctors keep in mind during venipuncture. In the earlier days, the nurse directly takes the blood from the vein with the help of the needle. But, this process has lots of disadvantages.

A patient can face lots of problems when he or she is giving the blood. Moreover, when the patient is a small kid, he may move his hands at the time of vein puncturing. This creates lots of difficulties. Transfusion is difficult during some conditions when the patient is suffering from cancer, he is old, has shrinkage skin, he is restless, suffering from drug abuse, obese or he is a burn victim. Keeping in mind all these, the doctor should maintain some techniques to make the process successful.

1. The doctor suggests the patient not to eat heavy or drink alcohol while coming for transfusion. It is better not to drive the car alone while coming to the chamber. The patient should has constant calm mind when coming to the clinic.

2. When the patient comes in the clinic, he or she can sit quietly for some time to reduce the tension.

3. When the patient is ready, the nurse cleans the hands with gel cleanser or soap and water. This ensures no germ in the body.

4. The doctor does some of the special tests, and then the process of venipuncture is ready. The professional find the vein, but she punctures the vein with the help of the needle and draws the blood.

The use of the needle is becoming not as popular in these days as it is difficult to find the vein at times. One of the most effective ways to find the right place of the vein is by the help of a machine or the vein viewing system. There are various companies that offer this type of instrument for the doctors to make the process of venipuncture easier. This instrument is having lots of benefits as compared to the needle puncturing.

Godwin Moses is a reputed author and he writes various articles on medicine and various latest medical advancements. He suggests the doctors to use the right type of vein viewing system for the perfect blood transfusion.
