Background technology
For transfusion, the syringe of blood transfusion mostly is disposable use, before use, on syringe needle, cover has pin cap, avoid syringe needle to contact with extraneous, and after syringe is used, medical personnel often can not find the pin cap taking off on former cause syringe needle, or not free by reasons such as pin cap sleeve return, make the syringe needle of the syringe after using directly outside exposed, caused syringe needle pollution and the injury of environment to external world after using, if cover back stitching is emitted, because the internal orifice dimension of pin cap is less, in the process of cover back stitching cap, increased the risk that medical personnel are punctured, very easily medical personnel are damaged.For solving this class problem, in prior art, there is a class injection needle, in syringe needle outside, add safety sleeve, but through using, how can there is the phenomenon coming off in this class safety sleeve, the syringe needle pollution of environment and the problem of injury to external world of the syringe after still can not solution use very in the extruding of more rubbish and collision process.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of easy to use, safety injector of not being prone to obscission.
For solving the problems of the technologies described above, this utility model provides a kind of safety injector, comprise syringe and the syringe needle that is connected in syringe leading section, described syringe outer cover is provided with safety sleeve, described safety sleeve is inner is provided with collar one near syringe afterbody end, on described collar one, be provided with the contact one extending forward, described syringe needle comprises pintle, is arranged with collar two on described pintle.
Preferably, collar two is round table-like, and two larger ends of round table-like collar are towards back end of syringe portion, and larger middle mind-set collar two inner recess of described round table-like collar two make collar two form the contact two extending to syringe end.
Preferably, collar one internal diameter is pre-small post-large shape, and the minimum place of described collar one internal diameter adapts with syringe external diameter.
Preferably, contact one diameter on collar one is less than contact two diameters on collar two.
Preferably, back end of syringe portion is arranged with rubber ring for fixing, and described rubber ring for fixing can move on syringe.
Preferably, on syringe needle, cover has pin cap, and described pin cap rearward end is provided with draught line.
Preferably, described safety sleeve length is not less than the length of syringe leading section to syringe needle leading section distance.
In this utility model, collar one is arranged on safety sleeve inside and opens the rubber collar near syringe needle afterbody, rubber collar one is with the coaxial setting of safety sleeve and be fixedly connected with safety sleeve, and rubber collar one has a circle flange near syringe needle end, it is contact one, collar two is fixed by socket on the pintle on syringe needle, the contact two that on collar two, oriented syringe direction is extended, contact two external diameters are greater than contact one external diameter, while guaranteeing that safety sleeve is pushed ahead, contact one contacts with contact two, contact two plays one to contact one and stops fixing effect, the rubber ring for fixing that is socketed in syringe outside is moved forward to safety sleeve afterbody contact simultaneously, safety sleeve can not be moved backward, so just spacing by carrying out before and after safety sleeve, guarantee that safety sleeve there will not be the phenomenon that moves forward and backward or even come off.Disclosed safety injector in this utility model in addition, is arranged on the safety sleeve of injector syringe outside when syringe is not used, and effectively protective sleeve there will not be at this outside pin cap the phenomenon dropping.
Adopt the beneficial effect of technique scheme to be: all to adopt rubber as raw material collar one, collar two, play certain buffering and prevent the effect of pushing, contact one and contact two are set respectively on collar one and collar two, at syringe needle outer setting rubber ring for fixing, can guarantee that syringe is after use, safety sleeve is pushed ahead, syringe needle is played to the effect being isolated from the outside, guarantee the phenomenon that safety sleeve there will not be skew and drops, so also can be convenient to the syringe after using to reclaim, the syringe reclaiming can keep original shape, there will not be the phenomenon of bending and wearing and tearing, guaranteed the integrity of syringe, effectively prevented that the syringe needle after using from polluting to external world and injuring, the secondary that has prevented disease is relayed, the disclosed a kind of safety injector of this utility model, simple in structure, easy to operate, greatly reduce medical personnel's danger coefficient.
The disclosed a kind of safety injector of this utility model, the safety sleeve of using on it and relevant technology and method thereof are also applicable to other every medical apparatus and instruments that relates to syringe needle, as: other conventional medical apparatus and instruments pins such as hypodermic needle, entry needle, blood taking needle, transfusion needle.
