Abstract
The invention belongs to the field of medical instruments, and particularly relates to a syringe piston and three-guide-vane mandrel connecting structure. The syringe piston and three-guide-vane mandrel connecting structure is characterized in that a fixing mandrel head is processed at the front end of a three-vane mandrel, a piston is mounted on the fixing mandrel head, a mandrel push handle is processed at the tail end of the three-vane mandrel, and three guide vanes are processed in the middle of the three-vane mandrel. In conclusion, since a fixing ring is processed on the fixing mandrel head (3), stable and reliable working of the piston (2) can be guaranteed; due to the action of the guide vanes (5), stable and reliable working of the three-vane mandrel (4) in a syringe (1) can be guaranteed.
Description
Technical field
the invention belongs to medical apparatus field, specifically relate to the link structure of a kind of syringe piston and three prerotation vane core bars.
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 link structure of a kind of syringe piston providing and three prerotation vane core bars.
the present invention is achieved in that the link structure of a kind of syringe piston and three prerotation vane core bars, it is characterized in that: the front end at three core bars is processed with fixedly pin head, piston is fixedly being installed above 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, fixing 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, fixedly pin head 3 is selected the time processing molding in mould of PP polypropylene material, fixedly above pin head 3, be processed with retainer ring, 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 fixedly 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, owing to being fixedly processed with retainer ring above pin head 3, so guarantee that piston 2 working stabilities are reliable, 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 link structure of a syringe piston and three prerotation vane core bars, it is characterized in that: the front end at three core bars is processed with fixedly pin head, piston is fixedly being installed above 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.
