Abstract

A screw rubber plug prefill syringe comprises a rubber plug, a core rod and a sheath, wherein the rubber plug and the core rod are connected through threads, parameters of supporting thread saw teeth are 30 degrees and 3 degrees, the rubber plug is provided with internal threads, the front end of the core rod is provided with external threads which guarantee that the core rod can slide inside the sheath without being pulled out from the rubber plug, and also can be easily unscrewed from the rubber plug or screwed in after filling or before use. After filling with medicine, the unscrewed core rod and the syringe are separately packaged, thereby achieving the purposes of simple packaging and safe conveying. And the syringe has simple structure, easy realization of automation, and convenient production.

Description

Spiral plug precharging type syringe
Technical field
This utility model relates to a kind of precharging type syringe that adopts the spiral plug, belongs to technical field of medical instruments.
Technical background
Precharging type syringe is because of can effectively preventing cross infection in the use, and is easy to operate, can make full use of medicinal liquid, some high-grade medicines particularly, and noresidue liquid, occasion is fit to self-injection, broad market prospect in the open air.But current precharging type syringe is after liquid drug, and core bar and overcoat can not separate, and makes finished-product volume bigger, the packing instructions strictness, and easily medicinal liquid is extruded by collision, and cause waste, all cause very big inconvenience for simultaneously packing and transportation.
Summary of the invention
In order to overcome the inconvenience of precharging type syringe in packed and transported.This utility model provides a kind of employing spiral plug precharging type syringe, this syringe can be behind the intact medicinal liquid of fill, core bar is withdrawed from from plug, refill before use, can effectively prevent from because of being subjected to collide medicinal liquid to be extruded in the transportation, can greatly make things convenient for the packing and the transportation of precharging type syringe.
The technical scheme that its technical problem that solves this utility model adopts is: a kind of spiral plug precharging type syringe, comprise plug and core bar and overcoat, plug and core bar adopt and are threaded, plug is provided with female thread, the core bar front end is provided with external screw thread, so both can guarantee can from plug, not extract when core bar slides in overcoat, also can screw out or screw in plug after fill or before using like a cork, can not cause the slip or the rotation of plug simultaneously.Behind the intact medicinal liquid of this syringe fill, core bar can be withdrawed from from plug, refill before the use, so both can effectively prevent to be extruded because of colliding medicinal liquid in the transportation, greatly make things convenient for the packing and the transportation of precharging type syringe.
The beneficial effects of the utility model are: after the precharging type syringe liquid drug, core bar and the overcoat and the plug that seal medicinal liquid can be separated packing, both can improve the safety of pre-filled medicinal liquid in transportation, also core bar and the overcoat and the plug that seal medicinal liquid can be separated packing, thereby reach the purpose of simplifying packing.
Description of drawings
Below in conjunction with drawings and Examples this utility model is further specified.
Fig. 1 is precharging type syringe complete structure figure;
Fig. 2 is the plug structure chart;
Fig. 3 is core bar structure figure;
Fig. 4 is the structure chart that core bar has screwed out after the powder charge.
The specific embodiment
This utility model specific embodiment as shown in Figure 1, a kind of spiral plug precharging type syringe, comprise plug 2 and core bar 3 and overcoat 1, plug 2 and core bar 3 adopt and are threaded, supporting screw thread sawtooth parameter is 30 ° and 3 °, plug 2 is provided with female thread 4, core bar 3 front ends are provided with external screw thread 5 (Fig. 2, Fig. 3), so both can guarantee can from plug, not extract when core bar slides in overcoat, also can screw out or screw in plug after fill or before using like a cork, can not cause the slip or the rotation of plug simultaneously.
