Technical Field

The utility model relates to the field of medical care appliances, in particular to a needle extractor for an infusion port.

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.

SUMMERY OF THE UTILITY MODEL

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.

Drawings

FIG. 1 is a schematic structural diagram of the present invention.

Detailed Description

As shown in figure 1, the needle extractor for the transfusion port is made of stainless steel materials and comprises a bottom plate 1, a silica gel layer is fixed at the lower end of the bottom plate 1, a lower U-shaped groove 2 is formed in the front end of the bottom plate 1, a baffle 3 is fixed at the upper end of the bottom plate 1 and is positioned above the lower U-shaped groove 2, the baffle 3 is parallel to the bottom plate 1, a middle U-shaped groove 4 is formed in the baffle 3, the length direction of the middle U-shaped groove 4 is parallel to the length direction of the lower U-shaped groove 2, a vertical support rod 5 is fixed at the upper end of the bottom plate 1 at the rear side of the baffle 3, a lower clamping plate 6 and an upper clamping plate 7 are hinged on the support rod 5, the lower clamping plate 6 and the upper clamping plate 7 are arranged in a crossed mode, a clamping part of the lower clamping plate 6 is positioned below a clamping part of the upper clamping plate 7, an upper U-shaped groove 8 is arranged on the clamping part of the lower clamping plate 6, the upper U-shaped groove 8 is positioned above the middle U-shaped groove 4, the length direction of the upper U-shaped groove 8 is parallel to the length direction of the middle U-shaped groove 4, the clamping parts of the lower clamping plates 6 on the left side and the right side of the upper U-shaped groove 8 are provided with butterfly wing grooves 9, vertical convex columns 10 are fixed in the butterfly wing grooves 9, and anti-skid lines are processed on the lower end faces of the clamping parts of the upper clamping plates 7.

When the utility model is used, the bottom plate 1 is attached to the body of a patient, so that a transfusion harbor base buried in subcutaneous tissues of the patient is positioned in the lower U-shaped groove 2, the puncture part of a butterfly wing nondestructive needle penetrates through the middle U-shaped groove 4, the friction force between the bottom plate 1 and the skin of the patient can be increased by a silica gel layer at the lower end of the bottom plate 1, the stability of the bottom plate 1 in the needle pulling process can be ensured, meanwhile, when the indoor temperature is lower, the discomfort of the patient caused by the direct contact between the bottom plate 1 and the skin of the patient can be prevented, then the clamping parts of the upper clamping plate 7 and the lower clamping plate 6 are mutually far away, the bottom plate 1 is moved, the puncture part of the butterfly wing nondestructive needle penetrates through the upper U-shaped groove 8, the clamping part of the lower clamping plate 6 can block the upper end part of the butterfly wing nondestructive needle, the two butterfly wings of the butterfly wing nondestructive needle are respectively placed in the two butterfly wing grooves 9, and the convex column 10 penetrates through a hole on one side of the butterfly wing, then make the clamping part of punch holder 7 and lower plate 6 carry out the centre gripping to butterfly wing not damaged needle upper end and butterfly wing, the anti-skidding line of processing can increase the stability behind the butterfly wing not damaged needle upper end by the centre gripping on the 7 clamping part lower extreme of punch holder, stable bottom plate 1, make the clamping part of punch holder 7 and lower plate 6 together upwards rotatory, thereby realize pulling out the butterfly wing not damaged needle, pull out the needle back, because the clamping part of punch holder 7 and lower plate 6 can carry out the centre gripping to butterfly wing not damaged needle upper end and butterfly wing, consequently, can prevent after pulling out the needle that the butterfly wing not damaged needle loses control and stab medical personnel.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
