Abstract

The invention belongs to the field of medical instruments and particularly relates to a syringe tubular core bar with three ultrashort guide sheets and an anti-slip ring. The syringe tubular core bar is characterized in that a core bar head is made at the front end of a tubular core bar, a piston is disposed above the core bar head, a core bar push handle is made at the tail end of the tubular core bar, the three ultrashort guide sheets are made on the outside of the middle of the tubular core bar, and three rib plates are made in the center of the tubular core bar. In conclusion, the ultrashort guide sheets (5) are made on the tubular core bar, the cross section of the tubular core bar can be made very small, and raw materials are greatly saved; under the action of the ultrashort guide sheets (5), the tubular core bar (4) can operate stably and reliably in a needle cylinder (1).

Description

The syringe cylinder core bar of a kind of three prerotation vanes and anti-slip ring

Technical field

the invention belongs to medical apparatus field, specifically relate to the syringe cylinder core bar of a kind of three prerotation vanes and anti-slip ring.

Background technology

the core bar of the syringe using clinically at present, ubiquity the raw-material structural design of waste, because the syringe using is clinically disposable, so waste suitable surprising, medical personnel are in the time inhaling medicine and injection operation, also effort relatively of syringe core rod push-and-pull, and hands is easily from the landing of overcoat edge, thus cause the generation of malpractice.

Summary of the invention

object of the present invention, is just to overcome above-mentioned shortcoming, and the syringe cylinder core bar of a kind of three prerotation vanes that provide and anti-slip ring.

the present invention is achieved in that the syringe cylinder core bar of a kind of three prerotation vanes and anti-slip ring, it is characterized in that: the front end at cartridge type core bar is processed with pin head, piston is installed on pin head, be processed with core bar at the end of cartridge type cartridge type core bar and push away handle, be processed with three prerotation vanes in the outside of the medium position of cartridge type core bar, on the interior location of cartridge type core bar, be processed with three gussets.

Brief description of the drawings

below in conjunction with accompanying drawing, the present invention will be further described in detail.

fig. 1 is main cutaway view of the present invention.

fig. 2 is Fig. 1 " A-A " cutaway view.

fig. 3 is Fig. 1 " B-B " cutaway view.

fig. 4 is Fig. 1 " C-C " cutaway view.

in figure, each label declaration is as follows:

1, syringe, 2, piston, 3, pin head, 4, cartridge type core bar, 5, prerotation vane, 6, syringe flange, 7, core bar pushes away handle.

Detailed description of the invention

syringe 1 of the present invention is selected the time processing molding in mould of PP polypropylene material, the effect of syringe 1 is store medicinal liquid and piston 2 is slided in syringe 1, piston 2 is selected the time processing molding in mould of butyl rubber material, the effect of piston 2 is exactly the thrust that pushes away handle 7 by core bar, the medicinal liquid of syringe 1 interior storage is passed through to syringe needle, in patient body, inject, or the medicinal liquid of syringe 1 interior storage is carried out to other operation etc. by syringe needle, pin head 3 is selected the time processing molding in mould of PP polypropylene material, its effect is exactly fixed piston 2, cartridge type core bar 4 is selected the time processing molding in mould of PP polypropylene material, its effect is exactly to ensure that pin head 3 piston 2 working stabilities are above reliable, prerotation vane 5 is selected the time processing molding in mould of PP polypropylene material, its effect is exactly to ensure that cartridge type core bar 4 is reliable at the interior working stability of syringe 1, syringe flange 6 is selected the time processing molding in mould of PP polypropylene material, its effect is exactly easy to operate reliable and stable while injecting, core bar pushes away handle 7 and selects the time processing molding in mould of PP polypropylene material, its effect is exactly while working, ensure that cartridge type core bar 4 working stabilities are reliable.

in sum, the present invention is owing to being processed with prerotation vane 5 on cartridge type core bar 4, the cross section of cartridge type core bar 4 can be processed into so very littlely, can greatly save like this raw material, owing to there being the effect of prerotation vane 5, can ensure that the working stability of cartridge type core bar 4 in syringe 1 is reliable.

Claims

1. the syringe cylinder core bar of three prerotation vanes and anti-slip ring, it is characterized in that: the front end at cartridge type core bar is processed with pin head, piston is installed on pin head, be processed with core bar at the end of cartridge type cartridge type core bar and push away handle, be processed with three prerotation vanes in the outside of the medium position of cartridge type core bar, on the interior location of cartridge type core bar, be processed with three gussets.
