Description
Technical field
This utility model relates to a kind of syringe, specifically a kind of antifake injector.
Background technology
Syringe uses frequently within the hospital, it is all single use, just throw away after being finished, but existing syringe is just distinguished new syringe and with the syringe crossed, significantly do not distinguished after opening packaging on outer packaging bag, and if having people the words of putting together with the syringe crossed and the syringe opened the package, be difficult to distinguish, if there are some illegal businessman to repack with the syringe crossed, also cannot accomplish to distinguish, cause a lot of inconvenience.
Utility model content
The purpose of this utility model is to provide a kind of antifake injector, can well distinguish used syringe and untapped syringe, simple and practical.
The purpose of this utility model is achieved through the following technical solutions:
A kind of antifake injector, comprise stack shell, plunger, syringe needle, needle mount and pin lid, described plunger is movably arranged in stack shell, described syringe needle is installed in described needle mount, described needle mount is installed on described stack shell, and described pin lid is placed on described syringe needle, it is characterized in that: the upper inner of described pin lid has multiple pyramid type projection, the top of described pyramid type projection is connected with described needle mount, described pyramid type projection and described pin lid one-body molded.
Described pyramid type projection is perpendicular to described needle mount.
Take the packaging of syringe apart, when using syringe, unplug pin lid and extract medicinal liquid, when unpluging pin lid, pin lid is separated with needle mount, the top of the pyramid type projection of the upper inner of pin lid is separated with needle mount, and pyramid type projection stays the upper inner of pin lid, and at this moment syringe needle extracts medicinal liquid, throw away after being finished, because pin lid is separated with needle mount, leave vestige, so be easy to distinguish used syringe and original syringe.
Antifake injector beneficial effect described in the utility model is: can well distinguish used and untapped, simple and practical.
Accompanying drawing explanation
Fig. 1 is the overall schematic of antifake injector described in this utility model embodiment.
Detailed description of the invention
As shown in Figure 1, a kind of antifake injector described in this utility model embodiment, comprise stack shell 1, plunger 2, syringe needle 3, needle mount 4 and pin lid 6, described plunger 2 is movably arranged in stack shell 1, described syringe needle 3 is installed in described needle mount 4, described needle mount 4 is installed on described stack shell 1, described pin lid 6 is placed on described syringe needle 3, it is characterized in that: the upper inner of described pin lid 6 has multiple pyramid type projection 5, the top of described pyramid type projection 5 is connected with described needle mount 4, described pyramid type projection 5 is one-body molded with described pin lid 6, described pyramid type projection 5 is perpendicular to described needle mount 4.
Take the packaging of syringe apart, when using syringe, unplug pin lid 6 and extract medicinal liquid, when unpluging pin lid 6, pin lid 6 is separated with needle mount 4, the top of the pyramid type projection 5 of the upper inner of pin lid 6 is separated with needle mount 4, and pyramid type projection 5 stays the upper inner of pin lid 6, at this moment twitches plunger 2 syringe needle 3 and extracts medicinal liquid in stack shell 1, throw away after being finished, because pin lid 6 is separated with needle mount 4, leave vestige, so be easy to distinguish used syringe and original syringe.
