Abstract
The invention belongs to the field of medical apparatus and particularly relates to an injection syringe cylindrical core pin with four guide sheets. The injection syringe cylindrical core pin with the four guide sheets is characterized in that a core pin head is machined at the front end of the cylindrical core pin, a piston is mounted on the core pin head, a core pin push handle is machined at the tail end of the cylindrical core pin, a button is mounted on the core pin push handle, and the four guide sheets are machined in the middle of the cylindrical core pin. The injection syringe cylindrical core pin has the advantages that the guide sheets (5) are machined on the cylindrical core pin (4), so that the cross section of the cylindrical core pin (4) can be small, raw materials can be greatly saved, and the cylindrical core pin (4) can work in a syringe (1) stably and reliably under the effect of the guide sheets (5).
Description
Technical field
the invention belongs to medical apparatus field, specifically relate to a kind of syringe cylinder core bar of four 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 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 four prerotation vanes that provide.
the present invention is achieved in that a kind of syringe cylinder core bar of four prerotation vanes, 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 core bar and push away handle, button is installed on core bar pushes away handle, is processed with four prerotation vanes at the medium position of cartridge type core bar.
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, 8, button.
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, button 8 is selected the time processing molding in mould of PP polypropylene material, its effect is exactly convenient and reliable operation.
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)
1. the syringe cylinder core bar of four prerotation vanes, 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 core bar and push away handle, button is installed on core bar pushes away handle, is processed with four prerotation vanes at the medium position of cartridge type core bar.
