Problems solved by technology
[0002] There are many places for medical blood collection, such as fingertips, elbows, wrists, heels, earlobes, etc. For parts with veins, doctors can use needles to collect blood conveniently, which causes less pain to patients, but for places without veins Distributed parts, such as fingertips, heels, etc., can only be blood collected by puncturing the skin and squeezing the bleeding, which takes a long time and causes strong pain; however, the latter method of blood collection is mostly used for tolerance For weaker children, this blood collection method will cause greater pain and injury to the baby, especially when a large amount of blood needs to be collected, the wound needs to be squeezed repeatedly, which is a kind of continuous physical injury to the baby and to the family members. It is also a kind of psychological torture
