Abstract

The utility model relates to a safety vein indwelling needle, which comprises an indwelling soft needle, a puncture steel needle and a steel needle stand. The utility model is characterized in that the vein indwelling needle also comprises a sleeve for containing the puncture steel needle and the steel needle stand, and a handle covered the outer part of the sleeve in a sliding way; the handle is connected with the steel needle stand as a whole through a ribbed plate, and the sleeve is arranged with a sliding groove for the ribbed plate sliding; two lock holes are symmetrically arranged at the both sides of the handle inner wall, two lock bolts are arranged on the sleeve outer wall corresponding to the lock holes; after the puncturing is finished, the handle is slid, then the puncture steel needle is taken off to be locked and stored in the sleeve.

Description

The safety venous detaining needle

Technical field

This utility model relates to a kind of venous detaining needle.

Background technology

At present, known venous detaining needle is made up of syringe needle helmet, the soft pin of venous indwelling, puncture draw point.During clinical use, the syringe needle helmet is taken off, the puncture draw point leads the soft pin of venous indwelling to enter the vein blood vessel of human body.After seeing blood back, confirm the venipuncture success, the draw point that will puncture is extracted out, and only the soft pin of the softish venous indwelling of material is retained in the vein blood vessel.Medicinal liquid is by the soft pin input of venous indwelling human body.The soft pin of venous indwelling cooperates the use of blood anticoagulant, can be for repeatedly transfusion use in human vein safety indwelling time.So just avoided frequent puncture to cause suffering to the patient.

Yet, traditional venous detaining needle, when clinical manipulation was extracted the puncture draw point out, the draw point point that is stained with patient blood very likely caused medical personnel's accidental injury and infection, and depleted exposed puncture draw point pollutes environment, and causes difficulty for the medical waste special treatment.Simultaneously, also can't stop venous detaining needle is illegally re-used.Thereby, there is serious social danger hidden danger.

Summary of the invention

Technical problem to be solved in the utility model is to overcome the above-mentioned shortcoming of prior art, and a kind of safety venous detaining needle that draw point exposes and the draw point that can effectively prevent to puncture is repeated to use that punctures of avoiding in finishing the process of extracting the puncture draw point out in the puncture back is provided.

The technical scheme that this utility model adopted is, a kind of safety venous detaining needle comprises and keeps somewhere soft pin, puncture draw point and draw point seat, and wherein, above-mentioned venous detaining needle comprises that also the sleeve that holds puncture draw point and draw point seat and sliding sleeve are in the hands handle of sleeve outside; This handle is connected as a single entity by gusset and draw point seat, and sleeve is provided with the chute that slides therein for above-mentioned gusset; The inwall lateral symmetry ground of handle respectively is provided with a lockhole, and telescopic outer wall is provided with and the corresponding dead bolt of lockhole; Finish puncture back sliding handle, extract the puncture draw point out, the locking of puncture draw point also is built in the sleeve.

Above-mentioned safety venous detaining needle, wherein, the lockhole of handle inwall does not communicate with the outer wall of handle both sides.

The beneficial effects of the utility model are: after finishing puncture, in the process that the puncture draw point is extracted out with its firmly snap close in sleeve, avoided syringe needle to expose; And this snap close can not release, thereby plays the protection to medical personnel, patient and environment: 1. the draw point of avoiding puncturing is accidentally injured medical personnel; 2. the draw point that prevents to puncture is repeated to use; 3. prevent depleted exposed puncture draw point contaminated environment, be convenient to the medical waste special treatment.

The specific embodiment

Below in conjunction with accompanying drawing this utility model is described in further detail.

Fig. 1 shows the three-dimensional exploded view of this utility model safety venous detaining needle.As shown in the figure, safety venous detaining needle of the present utility model comprises helmet 1, the soft pin 2 of indwelling, puncture draw point 3, handle 4, sleeve 5.Before use, the syringe needle of puncture draw point 3 passes keeps somewhere soft pin 2, is entangled by helmet 1 with keeping somewhere soft pin 2, plays the effect that soft pin and puncture draw point are kept somewhere in protection.

Fig. 2 shows puncture draw point of the present utility model, handle and telescopic structural representation, and wherein, the syringe needle of puncture draw point is in the state of exposing.As can see from Figure 2, described sleeve 5 has cavity structure, and the part of described puncture draw point 3 and draw point seat 6 are received within the cavity of sleeve 5, and wherein, the afterbody of puncture draw point 3 is fixed on the draw point seat 6 that is connected as a single entity with handle 4.Handle 4 is enclosed within on the outer surface of sleeve 5, and can carry out on the outer surface of sleeve 5 along sliding slippage.Be provided with arc groove to the lateral symmetry of handle, be convenient to finger and grip the hands handle; Be provided with many parallel vertical protrusions on its surface, to increase the frictional force between finger and handle.In the present embodiment, handle 4 is connected as a single entity by a gusset 42 and draw point seat 6, as shown in Figure 4, is provided with the chute 52 that this gusset 42 of a confession slides therein on sleeve 5.Thereby, when sleeve 5 slides backward, drive draw point seat 6 and puncture draw point 3 moves together backward at handle 4.As shown in Figure 2, respectively be provided with a hidden lockhole 41 on the inwall lateral symmetry ground of the end of handle 4, lockhole 41 does not communicate with the outer wall of handle 4 both sides.Thereby the outer wall both sides at the end of sleeve 5 respectively are provided with a dead bolt 51 that can put in above-mentioned lockhole lock handle.Shown in Figure 2 is that the puncture draw point is in puncture state before.After finishing puncture, medical personnel slide backward handle 4, driving puncture draw point 3 retreats, the draw point 3 that will puncture is extracted out from keep somewhere soft pin 2, when handle 4 slides into sleeve 5 terminal, as shown in Figure 3, dead bolt 51 snap closes on the lockhole 41 on the inwall of handle 4 and the outer wall of sleeve 5, will puncture draw point 3 lockings and interior the plant in the sleeve 5.Thereby can protect medical personnel in operating process, not to be punctured draw point accidental injury and infection.Locked and built-in draw point 3 can be with sleeve 5 discard processing in the lump, because lockhole 41 does not communicate with the outer wall of handle 4 both sides, can't separate snap close between open keyhole 41 and the dead bolt 51 from handle outer, thereby the draw point of effectively avoiding puncturing exposes to hurt sb.'s feelings and be repeated and uses, and also the processing for the medical supplies rubbish that uses up provides safety guarantee.

Though description of the present utility model combines certain embodiments, but it should be understood by one skilled in the art that this utility model is not limited to embodiment described here, and can carry out various modifications and variations and do not deviate from spirit and scope of the present utility model.
