Abstract
The invention relates to an injector. The injector comprises a mandrel, a piston and a barrel body, one end of the barrel body is an opening for connecting with the mandrel, the other end is provided with a conical head for connecting with a needle head, one end of the mandrel is firmly connected with the piston and movably inserted in the barrel body, the outer diameter of the piston is consistent with the inner diameter of the barrel body, a sleeve shell fixed at one end of the barrel body is arranged at the periphery of the conical head, a mandrel head sleeve for protecting the conical head is arranged in the sleeve shell, a connecting groove matched with the mandrel head sleeve is formed in the other end of the mandrel, the mandrel is connected with the mandrel head sleeve through the connecting groove, and the connecting groove drives the mandrel to move. The injector is simple in structure, convenient to use and capable of effectively protecting the conical head or needle head, the rejection rate is lowered, and the use cost is reduced.
Description
Technical field
The present invention relates to technical field of medical instruments, particularly syringe.
Background technology
Syringe is a kind of utensil conventional in medical apparatus and instruments, and syringe common at present comprises conehead (syringe needle), needle tubing and core bar three parts and forms.Although it is simple, a little easy to use that it has structure, its shortcoming is also very outstanding.Its maximum shortcoming is: manufacturing enterprise in process of production with medical personnel before not using, generally find that this syringe conehead ruptures, the product of fracture cannot use, and easily causes syringe needle contaminated, occur malpractice.
Therefore, how structural innovation and improvement are carried out to existing ordinary syringe, ensure its carry out in the overall process of injecting not contaminated, be people thirst for always solve technical problem.
Summary of the invention
For the problems referred to above, the object of this invention is to provide a kind of structure simple, easy to use, the syringe of energy available protecting conehead or syringe needle, reduces scrappage, reduces the syringe of use cost.
Realize technical scheme of the present invention as follows:
Syringe; comprise core bar; piston and cylindrical shell; one end of cylindrical shell is set to the opening for connecting core bar; the other end is provided with the conehead for connecting needle; one end of core bar is fixedly connected with piston and is movably inserted in cylindrical shell; the external diameter of piston is consistent with the internal diameter of cylindrical shell; the all sides of described conehead are provided with the sheath body being fixed on cylindrical shell one end; the core bar headgear for the protection of conehead is provided with in sheath body; the other end of core bar is provided with the link slot adapted with core bar headgear, and core bar and core bar headgear are connected by link slot and have the function driving core bar movement.
One end of described core bar headgear is provided with the protector adapted with conehead, and the other end is provided with gripper shoe, and advantage is that conehead is placed in protector, can effectively protect conehead not to be damaged.
Described core bar headgear and sheath body, core bar are threaded connection, and core bar headgear outer surface is provided with external screw thread, the inwall of sheath body and link slot has the female thread adapted with external screw thread, and advantage is connected firmly, easy to use.
Have employed above-mentioned scheme, when not using, core bar headgear is connected with sheath body, core bar headgear by conehead seal protection, prevent it from surprisingly rupturing or cylindrical shell contaminated to scrap, increase unnecessary cost; During use, take off core bar headgear, be contained on core bar, conehead installs syringe needle, now can carry out dynamic core bar and absorb Pharmaceutical and inject, so just can effectively work, sheath body also has the degree of depth that can control inserting needle when injecting in addition, alleviates the work difficulty of medical worker; After use, take off core bar headgear and be arranged on conehead, the same with when not using conehead to be protected.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is further described.
As Fig. 1, syringe, comprise core bar 2, piston 3 and cylindrical shell 1, one end of cylindrical shell 1 is set to the opening for connecting core bar 2, the other end is provided with the conehead 4 for connecting needle, one end of core bar 2 is fixedly connected with piston 3 and is movably inserted in cylindrical shell 1, the external diameter of piston 3 is consistent with the internal diameter of cylindrical shell 1, described conehead 4 weeks sides are provided with the sheath body 5 being fixed on cylindrical shell 1 one end, the core bar headgear 6 for the protection of conehead 4 is provided with in sheath body 5, the other end of core bar 2 is provided with the link slot 21 adapted with core bar headgear 6, core bar 2 and core bar headgear 6 are connected by link slot 21 and have the function driving core bar 2 movement.
One end of described core bar headgear 6 is provided with the protector 61 adapted with conehead 4, and the other end is provided with gripper shoe 62, and advantage is that conehead is placed in protector, can effectively protect conehead not to be damaged.
Described core bar headgear 6 is threaded connection with sheath body 5, core bar 2, and core bar headgear outer surface is provided with external screw thread, the inwall of sheath body and link slot has the female thread adapted with external screw thread, and advantage is connected firmly, easy to use.
