[0002] Physical examination is the abbreviation of physical examination, which refers to the physical examination of the examinee through medical means and methods. It is the diagnostic link of medical treatment and is a means of diagnosis for symptoms or diseases and their related factors. The procedure of health examination is generally to complete blood tests on the premise of fasting. In the blood drawing test, the examinee's arm is often placed on the blood drawing arm holder, and then the medical staff will draw blood.

[0003] When drawing blood, patients have different heights. If their arms are placed on a support board of inappropriate height for a long time, they will feel uncomfortable and the needle will easily skip. At the same time, when drawing blood, medical staff need to tie the patient's arm to highlight the blood vessels. It is very troublesome and easy to lose the medical rubber band every time. In response to this technical problem, this application proposes an arm auxiliary support device for blood collection. Utility Model Content
