Background
The infusion port is called a complete implantable venous access port (TIVAP), also known as a chemotherapy pump. Mainly comprises a base for puncture of a butterfly wing needle and a catheter placed in a blood vessel. In 1982, the port of venous Transfusion (TIVAP) was first reported abroad, and since then it began to be applied clinically. In 1988, TIVAP was introduced in China, 1998, and TIVAP is first reported in China. With the continuous development of TIVAP and its numerous advantages, many hospitals in China gradually accept and apply the technology. The base of the transfusion port and the catheter part outside the vein are both buried in subcutaneous tissue, and the transfusion port is an implanted central venous transfusion device which can be left for a long time. Requiring minor surgical placement.
The pulling out of the implanted infusion port after the completion of fluid infusion is the last step in the use and maintenance of the venous infusion port, however, when the atraumatic needle of the butterfly wing of the infusion port is pulled out clinically according to the traditional method, the atraumatic needle of the butterfly wing of the infusion port is tightly matched with the base of the infusion port, the medical staff is easy to have needle stick injury when pulling out the needle, and the infection probability of the medical staff is greatly increased.

In order to achieve the purpose, the utility model provides the technical scheme that:
the utility model provides a needle ware is pulled out in infusion port, by stainless steel material manufacturing, comprising a base plate, U type groove has been seted up down to the bottom plate front end, the bottom plate upper end is fixed with the baffle, the baffle is located U type groove top down, U type groove in having seted up on the baffle, the bottom plate upper end of baffle rear side is fixed with vertical branch, the hinge is connected with lower plate and punch holder on the branch, lower plate and punch holder cross arrangement, the clamping part of lower plate is located the clamping part below of punch holder, U type groove has been seted up on the clamping part of lower plate, it is located well U type groove top to go up U type groove, all seted up butterfly wing groove on the lower plate clamping part of the upper U type groove left and right sides, all be fixed with vertical projection in the butterfly wing groove.
Specifically, the baffle is parallel to the bottom plate.
Specifically, the length direction of the middle U-shaped groove is parallel to the length direction of the lower U-shaped groove, and the length direction of the upper U-shaped groove is parallel to the length direction of the middle U-shaped groove.
Specifically, anti-skidding lines are machined on the lower end face of the clamping portion of the upper clamping plate.
Specifically, a silica gel layer is fixed at the lower end of the bottom plate.
Compared with the prior art, the utility model has the beneficial effects that:
the butterfly wing nondestructive needle clamping device is simple in structure and convenient to operate, when the butterfly wing nondestructive needle of a transfusion port is pulled out, the butterfly wing nondestructive needle can be clamped, meanwhile, the base can be effectively blocked, medical staff can be prevented from being injured by the butterfly wing nondestructive needle in the needle pulling process, meanwhile, the base can be effectively protected, pain of a patient during needle pulling is reduced, and meanwhile, the needle pulling is convenient and efficient.
