Abstract
The invention discloses an anti-pollution sterile syringe. The anti-pollution sterile syringe comprises an outer cylinder, a piston, a plunger and a syringe needle. The outer cylinder is internally provided with the piston having the same internal diameter as the outer cylinder; the middle of the circular surface of the piston is provided with a through hole penetrating the piston, the protruding surface of the piston is provided with a circular groove, the side surface of the piston is provided with sealing grooves, and the sealing grooves are internally provided with sealing rings; one end of the plunger is provided with a push-and-pull portion, and the other end is provided with a projection which passes through the through hole and is arranged in the circular groove of the piston; and the syringe needle is connected with the projection. According to the invention, the anti-pollution sterile syringe prevents liquid in the syringe from being polluted and inflected by bacteria, prevents the syringe from being utilized by someone with ulterior motives and accordingly prevents safety threats to people. The syringe is good in sealing effect in an application process, does not leak the liquid and is convenient to operate.
Description
Technical field
The present invention relates to technical field of medical instruments, particularly relate to a kind of anti-pollution asepsis injector.
Background technology
There is the probability of Reusability in current existing plain edition syringe, user is using the syringe of Reusability, liquid in syringe then can be polluted and bacterial infection, and if syringe utilized by intentionally personage, then can threaten the safety of people.
Summary of the invention
For the deficiency that prior art exists, object of the present invention just there are provided a kind of anti-pollution asepsis injector, avoid liquid in syringe to be polluted and the problem of bacterial infection, and good seal performance, prevent syringe from being utilized by intentionally personage and threaten people's safety.
To achieve these goals, the technical solution used in the present invention is such: a kind of anti-pollution asepsis injector, comprises urceolus, piston, piston boit, syringe needle, is provided with the piston identical with urceolus internal diameter in described urceolus; Be provided with in the middle of the rounded face of described piston run through piston through hole, raised face is provided with circular groove, side is provided with seal groove, is provided with sealing ring in sealing groove; One end of described piston boit is provided with push-and-pull portion, and the other end is provided with protruding and is arranged in the circular groove of piston through through hole; Described syringe needle is connected with projection.
As a kind of preferred version, described sealing ring has two, is arranged at the top and bottom of piston respectively.
As a kind of preferred version, described piston jacket is provided with politef cover, and is wrapped in by sealing ring in politef cover.
As a kind of preferred version, described push-and-pull portion is provided with circular push-and-pull ring.
As a kind of preferred version, described circular groove is with through hole concentric and diameter is larger than through hole.
As a kind of preferred version, described urceolus is provided with elastic force bar, described elastic force bar is provided with Elastic clamping plate.
Compared with prior art, beneficial effect of the present invention: syringe of the present invention avoids liquid in syringe and polluted and the problem of bacterial infection, prevent syringe from being utilized by intentionally personage and threaten people's safety, and in use good sealing effect, no leakage, simple operation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with specific embodiment, the invention will be further described.Following examples only for technical scheme of the present invention is clearly described, and can not limit the scope of the invention with this.
Embodiment:
As shown in Figure 1, a kind of anti-pollution asepsis injector, comprises urceolus 1, piston 2, piston boit 3, syringe needle 4, is provided with the piston 2 identical with urceolus 1 internal diameter in described urceolus 1; Be provided with the through hole 5, the raised face that run through piston 2 in the middle of the rounded face of described piston 2 and be provided with circular groove (owing to being provided with component, therefore in figure and not shown), side is provided with seal groove (owing to being provided with component, therefore in figure and not shown), be provided with sealing ring 6 in sealing groove; One end of described piston boit 3 is provided with push-and-pull portion 7, and the other end is provided with protruding 8 and is arranged in the circular groove of piston 2 through through hole 5; Described syringe needle 4 is connected with protruding 8; Described circular groove is with through hole 5 concentric and diameter is larger than through hole 5.Favorable sealing property of the present invention, when syringe is injected, piston 2 is pulled to urceolus 1 top, after injection terminates, projection 8 now through piston boit 3 top of through hole 5 can be engaged with the top of syringe needle 4, when being retracted by piston boit 3, under the effect of gmatjpdumamics, urceolus 1 top is pulled back in urceolus 1 together with syringe needle 4 again.
The preferred described sealing ring 6 of the present invention is in O shape; Described sealing ring 6 has two, is arranged at the top and bottom of piston 2 respectively; Be arranged with politef cover 12 outside described piston 2, and sealing ring 6 be wrapped in politef cover 12; The external diameter of described sealing ring 6 is greater than the internal diameter of urceolus 1.During use sealing ring 6 be extruded after elasticity the inwall of the outer wall of politef overcoat 12 and syringe urceolus 1 is extruded, reach the object of sealing.
The preferred described push-and-pull portion 7 of the present invention is provided with circular push-and-pull ring 9.During concrete enforcement, finger inserts in circular push-and-pull ring 9 and extracts or liquid medicine injection, and improve the safety of syringe, it is more convenient to operate.
The preferred described urceolus 1 of the present invention is provided with elastic force bar 10, described elastic force bar 10 is provided with Elastic clamping plate 11.When using syringe to make up a prescription to patient, medicine bottle can be clipped on Elastic clamping plate 11, pull circular push-and-pull ring 9 and draw.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle; can also make some improvement and distortion, these improve and distortion also should be considered as protection scope of the present invention.
