This utility model provides following technical scheme:

A kind of syringe of detachable core bar, be made up of core bar 1, piston 2, plug 3, syringe 4, capping 5, wherein, core bar 1 is connected with piston 21 and detachable, piston 2 and plug 3 combine afterwards and syringe 4 is connected, and the rear end that can realize the pre-filling injection solution 6 in needle cylindrical unit 4 encapsulates, and capping 5 is attached thereto in the front end of syringe 4 and realizes encapsulating the front end of preliminary filling catheter lock solution 6 wherein.

As preferably, the connection between core bar 1 with piston 2 can be threaded, and taper pin connects the one in (female Luer), rotary clamp type connection etc.

As preferred piston 2 and the connection between plug 3 can be threaded, draw-in groove connect in one.

As preferably, core bar 1 is made up of fast joint 11, cross core bar 12, seat ring 13, and wherein core bar 1 is in mating connection by the fast access slot 21 on fast joint 11 and piston 2.

As preferably, piston 2 is made up of fast access slot 21, piston body 22, and plug 3 is made up of rubber plug body 31 and connecting hole 32, and piston 2 has been coordinated by connecting hole 32 and piston body 22 with the connection of plug 3.

As preferably, syringe 4 is made up of scale 41, needle cylindrical unit 42, turncap 43, joint 44, play the effect of splendid attire preliminary filling catheter lock solution, its rear end completes sealing by piston 2 and plug 3, and its front end completes the sealing to preliminary filling catheter lock solution by turncap 43, joint 44 and capping 5.

As preferably, capping 5 is made up of female Luer 51, cap body 52, and cap body 52 is provided with many convex tendons or groove, and the joint 44 on female Luer 51 and syringe and turncap 43 screw sealing.

The beneficial effects of the utility model are, syringe core rod is become demountable structure form with plunger designs by this utility model, decrease the Package size of syringe products, are convenient to produce in enormous quantities; The core bar of quick combination can be reused, and effectively saves material.
