Abstract
The invention belongs to the field of medical instruments and particularly relates to a syringe core bar with three ultrashort guide sheets. According to implementation, the syringe core bar is characterized in that a core bar head is made at the front end of a triple-sheet core bar, a piston is disposed above the core bar head, a core bar push handle is made at the tail end of the triple-sheet core bar, and the three ultrashort guide sheets are made in the middle of the triple-sheet core bar. In conclusion, the ultrashort guide sheets (5) are made on the triple-sheet core bar, the cross section of the triple-sheet core bar can be made very small, and raw materials are greatly saved; under the action of the ultrashort guide sheets (5), the triple-sheet core bar (4) can operate stably and reliably in a needle cylinder (1).
Description
Technical field
the invention belongs to medical apparatus field, specifically relate to a kind of syringe core rod of three prerotation vanes.
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 when inhaling medicine and injection operation, syringe core rod push-and-pull is effort relatively also, and hands is easily from the landing of overcoat edge, thereby causes the generation of malpractice.
Summary of the invention
object of the present invention, is just to overcome above-mentioned shortcoming, and the syringe core rod of a kind of three prerotation vanes that provide.
the present invention is achieved in that a kind of syringe core rod of three prerotation vanes, it is characterized in that: the front end at three core bars is processed with pin head, piston is installed on pin head, at the end of three core bars, be processed with core bar and push away handle, at the medium position of three core bars, be processed with three prerotation vanes.
Accompanying drawing explanation
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, three core bars, 5, prerotation vane, 6, syringe flange, 7, core bar pushes away handle.
The specific embodiment
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 by core bar, to push away the thrust of handle 7, 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, three core bars 4 are selected the time processing molding in mould of PP polypropylene material, its effect is exactly to guarantee 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 guarantee that three core bars 4 are 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, guarantee that three core bar 4 working stabilities are reliable.
in sum, the present invention is owing to being processed with prerotation vane 5 on three core bars 4, the cross section of three core bars 4 can be processed into so very littlely, can greatly save raw material like this, owing to there being the effect of prerotation vane 5, can guarantee that the working stability of three core bars 4 in syringe 1 is reliable.
Claims (1)
1. the syringe core rod of three prerotation vanes, it is characterized in that: the front end at three core bars is processed with pin head, piston is installed on pin head, at the end of three core bars, is processed with core bar and pushes away handle, at the medium position of three core bars, be processed with three prerotation vanes.
