It can be difficult for the nurse to find the blood vessel and inject precisely because of children’s thick fat layer. The ache caused by injection failure will bring mental obstacles like fear to children against treatments.
This Blood Vessel Detector uses infrared light, which can detect the location of blood vessels accurately. Moreover, it can also distinguish arteries from veins according to the direction of blood flow.
Putting this director on children’s arm will make it easy for the nurse to find the blood vessel’s position and inject precisely. It can also enable children to overcome the fear through its colorful appearance.
