Abstract
The utility model discloses a medical needle-stab proof device, which is characterized in that a locking buckle is arranged in a casing, a baffle block is arranged in the locking buckle, and the baffle block has a through hole through which a needle tube can pass through. Because the medical needle-stab proof device provided by the utility model adds a needle-stab proof device, the locking buckle is arranged in the casing and the baffle bock is arranged in the baffle buckle, after the normal operations of transfusion, injection and stab are completed in the using process, medical staffs can pull out needle tubes and move needle tube seat, and the needlepoint of the needle tube enters into the locking buckle of the needle-stab proof device; the needlepoint cannot extend out of the locking buckle and the casing to prevent needle stab and avoid infection danger that the health workers are stabbed by needlepoint, and the device has the advantages of simple structure and convenient use.
Description
Technical field:
This utility model 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 purpose of this utility model 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, the technical solution of the utility model is: a kind of 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.
This utility model 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 transfusion, the action of 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 this utility model is simple in structure because of being infected by pricking wound, easy to use.
Description of drawings:
Fig. 1 is the structural representation of this utility model one embodiment
Fig. 2 is the user mode sketch map of Fig. 1
Fig. 3 is this utility model and a kind of sketch map that cooperates of remaining needle
The specific embodiment:
The utility model will be further described below in conjunction with drawings and Examples.
This utility model 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 characterized in that: in shell 2, be provided with snap close 5, in snap close 5, establish a block 6, this block 6 has the through hole 4 that passes through for needle tubing 1, 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, space between long and short " 7 " font shell fragment is the 0.5-3 millimeter, the front end of needle tubing seat has a male member 17, and from considering the angle of cost, shell 2, snap close 5, block 6 all adopt plastic material.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 in this utility model 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 Needlestick prevention 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.
