Description

A kind of novel injector

Technical field

The utility model is related to medical instruments field, and in particular to a kind of novel injector.

Background technology

At present, existing syringe mostly is plastic injector for temporary use, is made up of syringe needle, sleeve, piston, needle guard, is using When, needle guard is removed, after injection is finished, because syringe is different with the processing mode of syringe needle, need to separate syringe and syringe needle, individually Collect, individually process.At present, the disposable syringe after use can be unmake with shape-destruction device, or be unmake pin using manual After head, syringe are separated, syringe needle can be directly placed into anti-stab container or press from both sides curved more than 90 degree with pliers, syringe pliers pinch off breast Head, medicining liquid dipping of the use containing effective chlorine 1000mg/L more than 60 minutes, then concentrating again carries out harmless treatment, manually carries out When syringe needle, syringe are separated, treatment people is easily stabbed, cause cross-infection.

The content of the invention

The purpose of this utility model is to provide a kind of novel injector, and simple structure can quickly divide after the completion of injection From syringe needle, and treatment people will not be stabbed.

The utility model solves the technical scheme that its technical problem adopted：A kind of novel injector, including syringe, pin Head, syringe needle cover, rubber stopper, pull bar, the syringe needle is connected by needle holder with syringe, and the needle holder is near one end of syringe Pull handle plate is arranged with, stopper slot is provided with the inside of pull handle plate, needle holder is provided with draw-in groove, syringe needle near one end outer wall of syringe Tearing mark is arranged with seat wall, the tearing mark is located at the centre of two pull handle plates, and the syringe needle cover is detachably located at syringe needle On seat, the inwall of the openend of syringe needle cover is provided with buckle, and buckle is connected with draw-in groove, on the syringe needle cover opening end outer wall Spacing fin is arranged with, the spacing fin is in mating connection with stopper slot, and on the syringe needle cover outer wall draw ring is arranged with, The draw ring is located on same straight line with spacing fin.

Further, the elastic construction of sector is arranged with the syringe needle cover outer wall, the elastic construction is located at two limits The centre of position fin, when syringe needle cover is strutted, elastic construction can produce tension force, prevent external force from destroying syringe needle cover, it is to avoid syringe needle The protective effect of cover disappears.

The utility model has the advantages that：Simple structure, after the completion of injection can quick separating syringe needle, syringe needle cover Can using it is front, using rear protect syringe needle, prevent needlestick injuries treatment people.

In figure：1 syringe needle, 2 needle holders, 21 pull handle plates, 22 stopper slots, 23 draw-in grooves, 24 tearing marks, 3 syringe needle covers, 31 draw rings, 32 spacing fins, 33 elastic constructions, 34 buckles, 4 syringes, 5 rubber stoppers, 51 pull bars.

Specific embodiment

The utility model is described in further detail presently in connection with accompanying drawing.

A kind of novel injector according to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, including syringe 4, syringe needle 1, syringe needle cover 3, Rubber stopper 5, pull bar 51, the syringe needle 1 is connected by needle holder 2 with syringe 4, and the needle holder 2 is near one end pair of syringe 4 Title is provided with pull handle plate 21, and the inner side of pull handle plate 21 is provided with stopper slot 22, and needle holder 2 is provided with card near one end outer wall of syringe 4 Groove 23, is arranged with tearing mark 24 on the wall of needle holder 2, the tearing mark 24 is located at the centre of two pull handle plates 21, the syringe needle Cover 3 is detachably located in needle holder 2, and the inwall of the openend of syringe needle cover 3 is provided with buckle 34, and buckle 34 coordinates with draw-in groove 23 and connects Connect, spacing fin 32, the spacing fin 32 and the company of being engaged of stopper slot 22 are arranged with the openend outer wall of the syringe needle cover 3 Connect, play spacing effect, while spacing fin has the effect strengthened, on the outer wall of syringe needle cover 3 draw ring 31 is arranged with, The draw ring 31 sets on the same line with spacing fin 32.

Further, the elastic construction 33 of sector is arranged with the outer wall of syringe needle cover 3, the elastic construction 33 is located at two The centre of individual spacing fin 32, when syringe needle cover 3 is strutted, elastic construction 33 can produce tension force, prevent external force from destroying syringe needle cover 3, it is to avoid the protective effect of syringe needle cover 3 disappears.

When unused, syringe needle cover is covered on outside syringe needle, is played a protective role, after syringe is using finishing, by syringe needle cover In stopper slot on spacing fin and needle stand, card is heard during installation, work(will be snapped into and be placed in draw-in groove, using distraction forcep Or similar means, the bipod of distraction forcep is placed in draw ring, the spacing fin on syringe needle cover is applied to power by stopper slot On pull handle plate, by the opening force of pull handle plate, the tearing mark on needle stand is strutted, smoothly removed needle stand from syringe, this mistake Journey syringe needle is protected by syringe needle cover, and operator need not contact syringe needle, be prevented effectively from and stab operator, the syringe needle removed and syringe It is individually positioned in surge drum, does next step process.
