Finally, the micro motor one 5 and the micro motor two 7 are started to slowly pull out the blood collection needle, and a sterile cotton ball or gauze is pressed against the puncture point until bleeding stops, and the cotton ball or gauze is fixed with adhesive tape to prevent rebleeding.

[0029] The main purpose of the device is not to completely replace the operation of blood collection by medical staff, but to provide an auxiliary means in the blood collection process. Especially for beginners or inexperienced medical staff, the device can be used as a training tool to help them better understand how to correctly position the blood collection needle and better learn how to position and puncture the blood collection needle through the machine action set by the teaching teacher.

[0030] In addition to the above use scenarios, in some special cases, such as emergency rescue scenarios, the on-site medical resource is limited, and through such a device, part of the non-professional personnel can be quickly trained to assist in blood collection. For example, the blood vessels of a plurality of patients are first positioned and preliminarily punctured by medical staff. Due to the structural design of the device, the blood collection tube can continue to work while maintaining the correct verticality, and subsequent blood collection and collection of the blood collection tube and hemostasis for the patient can be completed by the non-professional personnel who have been temporarily trained.
