Description
Technical field:
The present invention relates to the technical field of medical injection and vein puncture, is a kind of remaining needle and anti-pricking wound devices such as other syringe and transfusion device of being used for specifically.
Background technology:
The remaining needle that uses or other syringe and transfusion device are not mostly prevented the safety guard of pricking wound at present; medical personnel infuse normally or inject puncture procedure finish extract pin after; often with the pin extracted with defeated; having annotated the container of liquid handles together; though extreme care when handling; but according to existing incomplete statistics data; medical personnel are handling these pins with defeated; when having annotated the container of liquid; average evenly once above for each person every year by the situation of pricking wound; and on average whenever be wounded by stabbing infected danger is just arranged for 6 times; as run into the patient and suffer from infectious disease, infected danger just increases greatly behind the pricking wound medical personnel personnel that extract on one's body from the patient.
Summary of the invention:
The object of the present invention is to provide a kind of anti-pricking wound device that is used for remaining needle and other syringe and transfusion device, it can prevent medical personnel when handling these pins with defeated, as to have annotated liquid container by pricking wound, thereby avoided infected danger behind the pricking wound medical personnel.
To achieve these goals, technical scheme of the present invention is: medical device for preventing puncture wound by needle, the needle tubing seat that it mainly comprises needle tubing, is connected with needle tubing, the shell that supplies needle tubing to pass through, it is characterized in that: be provided with snap close in the enclosure, establish a block in snap close, this block has the through hole that passes through for needle tubing; Needle tubing is established a boss, be provided with the groove that matches with the needle tubing boss at block for the through hole that needle tubing passes through, inwall at shell is provided with groove, the front end of shell has a boss, and the cavity that can hold block is arranged in the described snap close, and the surface of snap close is provided with male member, there is a pedestal rear end of snap close, base vivo wall is provided with jog, and the surface of block is provided with convex-concave portion, and the front end of snap close has two " 7 " font shell fragments.
The present invention is owing to set up anti-pricking wound device, be provided with snap close in the enclosure, in snap close, establish a block, during use after finishing in normal defeated, the action of fluid injection puncture procedure, medical personnel extract needle tubing, and mobile needle tubing seat, the needle point of needle tubing is entered in the snap close of anti-pricking wound device, because the effect needle point of snap close can not stretch out snap close and shell, thereby prevented pricking wound, avoided the danger of medical personnel, and the present invention is simple in structure because of being infected by pricking wound, easy to use.
Description of drawings:
Fig. 1 is the structural representation of one embodiment of the invention
Fig. 2 is the user mode sketch map of Fig. 1
Fig. 3 is the cooperate sketch map of the present invention with a kind of remaining needle
The specific embodiment:
The invention will be further described below in conjunction with drawings and Examples.
The present invention mainly comprises needle tubing 1, the needle tubing seat 3 that is connected with needle tubing 1, the shell 2 that supplies needle tubing to pass through, it is different from prior art and is: be provided with snap close 5 in shell 2, in snap close 5, establish a block 6, this block 6 has the through hole 4 that passes through for needle tubing 1, requires and each specification draw point interference fits for the through hole that needle tubing passes through at block, can play the boss effect that stops on the needle tubing, needle tubing 1 is established a boss 7 during enforcement, is provided with the groove 8 that matches with the needle tubing boss at block for the through hole that needle tubing passes through; For cooperate with snap close 5 comparatively closely and defeated with medical treatment such as existing remaining needle, annotate the supporting use of utensil, present embodiment is provided with groove at the inwall of shell, the front end of shell has a boss 10, shell can be circular, also can be square; The cavity 11 that can hold block is arranged in the described snap close, the surface of snap close is provided with male member 12, there is a pedestal 13 rear end of snap close, base vivo wall is provided with jog 14, the surface of block is provided with convex-concave portion, the front end of snap close has two " 7 " font shell fragments, one of them is long " 7 " font shell fragment 15, another is short " 7 " font shell fragment 16, long, space between the short shell fragment is the 0.5-3 millimeter, the front end of needle tubing seat has a male member 17, from considering the angle of cost, shell 2, snap close 5, two " 7 " font shell fragments of the front end of snap close and block 6 all adopt plastic material.This anti-pricking wound apparatus structure is simple, easy to operate, and anti-all parts of pricking wound device all adopt plastic material, and the cutting edge of a knife or a sword mouth of avoiding other metal material to bring is stabbed problem.Be prior art about the casing seat in the accompanying drawing 18, conduit 19, intermediate plate 20, catheter block 21, helmet 22, calparine cap 23, blood back device 24, fin 25, do not repeat them here.
The male member 17 of the needle tubing seat front end during use among the present invention can withstand the block 6 in the snap close 5, block 6 is slided at the cavity 11 of snap close, can prevent that on the other hand needle tubing seat 3 from rotating about, withstand casing seat 18 at the boss 10 of needle tubing by the shell front end, after the action of normal transfusion injection puncture procedure finishes, medical personnel extract needle tubing 1, and mobile needle tubing seat 3, when needle tubing 1 moves on to the position of long " 7 " font shell fragment 15 and short " 7 " font shell fragment 16, can listen " card When " one, the needle point of expression needle tubing 1 enters in the snap close 5 of anti-pricking wound device, because the effect needle point of snap close can not stretch out snap close and shell, the needle point that is needle tubing 1 is in the lock state, when continuing to pull out pin backward, this Needlestick prevention device can break away from casing seat, this moment, needle point was locked in the cavity by length " 7 " font shell fragment 15 and short " 7 " font shell fragment 16 containings that is positioned at shell 2, and because the effect of block 6, the needle point of needle tubing 1 is in crag-fast position, needle point can not stretch out long " 7 " font shell fragment 15, short " 7 " font shell fragment 16 and shell 2, thus avoided medical personnel because of be subjected to the danger of cross infection by pricking wound effectively.The present invention can be used for medical apparatus and instruments such as various remaining needles and other syringe, transfusion device.Remaining needles such as the artery and vein remaining needle of present used style such as penholder shape, dosing kettle formula, Y type closed, butterfly shape, anti-adverse current type formula all can supportingly use.
