Furthermore, the needle seat is of a hollow structure, the top surface of the needle seat is provided with a bottle stopper puncture needle head fixing seat, and the bottom surface of the needle seat is provided with an infusion tube penetrating hole.

Further, the holder is including articulating in the grip block of needle file side, is equipped with relative profile of tooth protruding strip on the centre gripping terminal surface that grip block and needle file terminal surface formed, the open end of grip block is equipped with box fretwork piece, is equipped with the son on the needle file terminal surface rather than the joint and detains protruding piece, box fretwork piece detains protruding piece looks joint with the son. Furthermore, the needle seat is made of hard plastic.

Furthermore, a bottle stopper needle cap is sleeved on the bottle stopper puncture needle head.

Furthermore, the extension tube is a plastic hose, the material of the extension tube is the same as that of the infusion tube, and the length of the extension tube is 35-50 cm.

Has the advantages that: the utility model provides a prevent transfusion system of bottle plug needle slippage is equipped with holder and extension pipe on the needle file of this transfusion system, fixes then utilizes the holder to press from both sides tightly bottle plug puncture syringe needle through the extension pipe, can effectively avoid bottle plug puncture syringe needle to deviate from the rubber bottle plug, and this easy operation is convenient, and is applicable to the infusion bag (medicine bottle) of any bore and special-shaped bottleneck, uses the transfusion system fixes bottle plug puncture syringe needle, but furthest's lightening patient economic loss ensures infusion safety, reduces the chance of infecting in the hospital, improves the satisfaction, is particularly useful for children's infusion, blood transfusion, chemotherapy medicine, when using expensive medicine, the patient that the unclear consciousness is fidgety and well-moving, the patient of transporting, the patient that the bed need stand up etc.. Therefore, the infusion apparatus of the utility model has wide application prospect.
