When first protection cap is taken off extract deployed medical fluid again and inject；But needle portion will be exposed to after injection
Outside, easily lead under the action of surrounding enviroment recycling syringe during medical staff with the personnel on periphery by syringe needle
Caused by surprisingly puncture injury, for this problem, in such as country Publication No. 205252220U, publication date 20160525
Shown in patent document: " scalable needle injector " discloses a kind of by setting scalable knot for the syringe needle on syringe
Structure realizes the hiding protection of syringe needle after injection, for another example domestic Publication No. 201847988U, publication date 20110601
Shown in patent document: in " disposable safe injection needle head and syringe ", by syringe needle part be arranged one shake
Bar slide block mechanism enables Slipper to cover at syringe needle to play protecting effect.All there is knots for two of them technical solution
Structure is complicated, and structure is complicated will correspondingly will appear and be easy problem at high cost that is impaired invalid, and fabricating.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of medical anti-injection devices surprisingly punctured, with solution
Certainly the syringe needle of current injector be easy to cause unexpected the problem of puncturing injury after terminating injection.
To solve the above problems, the utility model provides following technical solution:
A kind of medical anti-injection device surprisingly punctured, it includes injecting empty cylinder；The one end for injecting empty cylinder is provided with cream
Head, syringe needle pass through being fitted on the empty cylinder of injection between nipple and pintle；It is right on the cylindrical outer side surface for injecting empty cylinder
Title is opened there are two sliding slot；Draw runner is provided in sliding slot；One end adjacent with nipple is provided with connection frame on draw runner, and draw runner is another
The operating block stretched out from sliding slot notch is provided on one end；Protection sheath is installed on connection frame；And draw runner is on the chute
Protect sheath that can cover the needle point position of syringe needle when side.
Preferably, sliding slot notch shape is inverted T-shaped, and draw runner is the T shape draw runner matched with the inverted T-shaped sliding slot.
Further, limiting slot is provided with along the circumferential direction for injecting empty cylinder at the both ends of sliding slot.
Preferably, protection sheath is respectively plastic cement parietal layer, elastic rubber layer and medical cotton layer from outside to inside.
Preferably, graduation indication line is provided in the region between two sliding slots of periphery for injecting empty cylinder.
The utility model the utility model has the advantages that
The utility model improves common syringe, sliding slot is added on injecting empty cylinder, by draw runner in cunning
Sliding in slot drives connection frame and protects protection of the sheath to syringe needle, so that solving the syringe needle of current injector is terminating to infuse
Unexpected the problem of puncturing injury is be easy to cause after penetrating, on the other hand, the utility model structure is simple, molding easy to process, together
When all parts between be cooperatively connected reliable, remaining bloodstain and injection can be effectively prevent after injection on syringe needle to peripheral ring
Border pollutes.

Specific embodiment
With reference to the accompanying drawing and the utility model is described further in specific embodiment:
Embodiment:
Referring to Fig.1, the present embodiment provides a kind of medical anti-injection devices surprisingly punctured, it includes injecting empty cylinder 1；It is infusing
The one end for penetrating empty cylinder 1 is provided with nipple 11, and syringe needle 2 passes through being fitted on the empty cylinder 1 of injection between nipple 11 and pintle 21；
Sliding slot 3 there are two symmetrically being opened on the cylindrical outer side surface for injecting empty cylinder 1；Draw runner 4 is provided in sliding slot 3；On draw runner 4 with nipple
11 adjacent one end are provided with connection frame 41, and the operating block 43 stretched out from 3 notch of sliding slot is provided on the other end of draw runner 4；
Protection sheath 42 is installed on connection frame 41；And draw runner 4 protects sheath 42 that can cover syringe needle 2 at the side on sliding slot 3
Needle point position.In the present embodiment, the radial section for injecting empty cylinder 1 is fusellal fabric small in ends and broad in the middle, and sliding slot 3
It is opened in and injects the most thick position of 1 upper side of empty cylinder；Connection frame 41 is umbrella-shaped structure simultaneously, and sheath 42 is protected to be mounted on umbrella company
It connects on the small end face of frame.
Referring to Fig. 2 and Fig. 3,3 notch shape of sliding slot is inverted T-shaped, and draw runner 4 is the T shape matched with the inverted T-shaped sliding slot 3
Draw runner is provided with limiting slot 31 along the circumferential direction for injecting empty cylinder 1 at the both ends of sliding slot 3.In the present embodiment, the bottom of T shape draw runner 4 is wide
