This painless blood collection pen uses negative pressure technology to accurately pierce capillaries below the dermis layer of the skin for detection, so that patients do not feel sharp pain during blood collection, and can effectively relieve the tension caused by needle pricking. The depth of the needle can be adjusted in four positions. The flat and round appearance design makes the product more stable and comfortable to grasp when in use.
