Description
Technical field
This utility model relates to a kind of syringe, specifically a kind of precharging type syringe.
Background technology
We know that syringe is a kind of medical apparatus commonly used, and it generally comprises overcoat, piston, core bar, needle holder.Piston is inserted in the core bar front portion, can be driven in overcoat by core bar to twitch back and forth, and needle holder is located at the overcoat front end, is used for connecting injection needle.Above-mentioned parts are general to be made mostly by plastic materials such as polypropylene, only is applicable to that disposable injection uses, and can not be used for the storaging liquid medicine for a long time.Because some medicinal liquids and plastics can react, more be unsuitable for carrying out the high-temperature sterilization sterilization, long term storage just may cause drug effect to reduce, lost efficacy even become noxious substance.And at present, how the packing and storing of liquid drug comprises with glass special low dose peace bottle with special packing container.The low dose peace bottle that glass is made, filling liquid is easy, and it is good to store the medicinal liquid chemical stability, can carry out the high-temperature sterilization sterilization, but because the thin matter of peace bottle wall is crisp, the breakage rate height, it is unfavorable that the packing and storing of medicinal liquid is caused, and has a strong impact on the injection use and the patient's body health of medicinal liquid.
Summary of the invention
Technical problem to be solved in the utility model is to overcome above-mentioned the deficiencies in the prior art, provides a kind of simple in structure, easy to use, both can be used as the medicinal liquid reservoir and has stored medicinal liquid, can be used as syringe carries out injection for curing to the patient precharging type syringe again.
The technical scheme in the invention for solving the above technical problem is: a kind of precharging type syringe, comprise overcoat, piston, core bar, it is characterized in that: overcoat is the hollow circular cylinder of glass processing, peg graft on the conehead of its front end and be fixed with entry needle, conehead and entry needle are equipped with a helmet outward, and hollow circular cylinder overcoat open rearward end is provided with the capping of a piston as the overcoat herb liquid in the overcoat, can slide in overcoat and seal, piston is connected with core bar.
This utility model is because overcoat adopts the hollow circular cylinder of glass processing, and filling liquid medicine within it in advance, the double effect of making the medicinal liquid capping of piston, against existing technologies, this utility model both can be used as the medicinal liquid reservoir and had stored medicinal liquid, was convenient to carry out the high-temperature sterilization sterilization, can be used as the disposable use of syringe again, it is simple in structure, and is easy to use.

Below in conjunction with drawings and Examples this utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the syndeton sketch map of this utility model piston and core bar.
Fig. 3 is the another kind of syndeton sketch map of this utility model piston and core bar.
1. protective sleeves among the figure, 2. entry needle, 3. helmet, 4. medicinal liquid, 5. piston, 6. overcoat, 7. core bar.
The specific embodiment
As can be seen from Figure 1, a kind of precharging type syringe comprises overcoat 6, piston 5, core bar 7, and its overcoat 6 is hollow circular cylinders of glass processing, and pegging graft on the conehead of its front end is fixed with entry needle 2, conehead and the entry needle 2 outer helmets 3 that are equipped with.Helmet 3 is used for preventing that the medicinal liquid in the hollow circular cylinder overcoat 6 from leaking from entry needle 2.Hollow circular cylinder overcoat 6 open rearward end, filling in advance has medicinal liquid 4 in the overcoat 6.Hollow circular cylinder overcoat 6 open rearward end portions are provided with a piston 5, and it as the capping of overcoat 6 herb liquids, can slide in overcoat 6 and seal simultaneously, and piston 5 is connected with core bar 7.
It can also be seen that from Fig. 1 this utility model helmet 3 outsides also are provided with a protective sleeve 1.Overcoat 6 outsides also are provided with the medicinal liquid scale, are used for quantitatively and clearly observing injection.
This utility model piston 5 is the branch body structure with core bar 7, and it can pack in split, links together during use.The back packing also can link into an integrated entity.Fig. 2 is the syndeton sketch map of this utility model piston 5 and core bar 7, and piston 5 rear portions are provided with a threaded connection groove, and core bar 7 front ends are provided with the protrusion bolt, and piston 5 is fixing through being threaded with core bar 7.Be threaded like this, piston 5 is not subjected to axial force, and medicinal liquid overflows in the time of can avoiding connecting.
Fig. 3 is the another kind of syndeton sketch map of this utility model piston and core bar.Piston 5 rear portions are provided with one and connect groove, and core bar 7 front ends are provided with a ring-like projection, and piston 5 and core bar 7 are connected and fixed through draw-in groove.
This utility model both can be used as the medicinal liquid reservoir and had stored medicinal liquid, was convenient to carry out the high-temperature sterilization sterilization, can be used as the disposable use of syringe again, and it is simple in structure, and is easy to use.
Claims (5)
