Description

Technical field [0001] The invention relates to medical needle extraction equipment, in particular to an automatic needle extraction assembly. Background technique [0002] In the process of medical rescue, it usually involves hanging IV, common drip injection head, such as Image 6 As shown, the structure includes a needle a, and a clamping piece b is provided on the needle. [0003] Because the entire infusion takes a long time, and it is impossible for the medical staff to monitor whether the patient’s infusion has been completed at any time, and when the liquid in the infusion bottle is almost finished, if the patient cannot find the medical staff, there is no Accompanied by family members, the patient's mood at this time will be very irritable. At this time, if the patient chooses to remove the needle by himself, he can only use the other hand that does not hang the IV. Although the current position of the needle will be Set up a wound dressing, but because the needle is still...
