Description

technical field [0001] The invention relates to an auxiliary device, in particular to an auxiliary device for drawing blood from arm veins used in the hematology department of a hospital. Background technique [0002] With the continuous development of medicine, blood test has become an indispensable part of clinical examination. The specific condition of the patient can be detected by blood test, which can be quickly diagnosed for the doctor. When drawing blood tests, the usual puncture site is a hand vein puncture. However, the success rate of puncture is affected by various aspects such as age, obesity, disease, environment, and blood vessels themselves. And for some thin, malnourished, elderly, obese, heart, kidney disease, allergies and other people with swelling and poor peripheral circulation, it is not easy to find veins. During the process, a little carelessness will puncture the vein and cause hematoma. However, for inexperienced operators, multiple punctures a...
