Abstract
The utility model discloses a kind of high pressure injector, comprise syringe body and push-and-pull ring, described syringe comprises injection tube and push rod, described push rod is plugged in injection tube, described push rod is provided with operating portion away from one end of syringe, wherein: described push-and-pull ring below is provided with mount pad, described mount pad middle part offers the groove of operating portion adaptation, described mount pad offers the hollow slots with push rod external diameter adaptation away from the one side of push-and-pull ring, aims to provide the high pressure injector that a kind of push-and-pull ring can reuse easily.
Description
Technical field
This utility model relates to a kind of medical device, and more particularly, it relates to a kind of syringe.
Background technology
Syringe is comprised of the foraminate syringe of front end band and the piston core bar that matches.Syringe is used for that a small amount of liquid or its are injected into region that other method cannot be approaching or from those local extractions out.When core bar is extracted, liquid or gas suck from syringe front end aperture, when core bar pushes, liquid or gas are extruded.By this process of syringe and syringe needle extraction or injecting gas or liquid, be called injection.
At present, application number on market is that the Chinese patent of CN201320089548.9 discloses a kind of safety injector with push-and-pull ring, and it comprises syringe, syringe needle and push rod, and the front end of syringe is provided with syringe needle joint, the rear end of syringe has opening, and the edge of the rear end of syringe is provided with grip part; Syringe needle is connected with syringe needle joint, and push rod is positioned at the center of syringe, and the front end of push rod is provided with piston, the inwall of piston and syringe closely cooperates, and the side of piston also offers lubrication groove, is filled with lubricating fluid in lubrication groove, the rear end of push rod is provided with push-and-pull ring, is also provided with broken part on push rod.The advantage of this utility model is: simple in structure; Push-and-pull ring replaces hand-pushing handle, easy to operate; The push rod that fractures after use, prevents that secondary from being used, safe; In piston side, be added with lubricating fluid, push-and-pull resistance is little.
Although this syringe is easy to use, its push-and-pull loop section in fact belongs to recoverable part, fractures and scraps after adopting the push-and-pull ring of this utility model to cause it once to use, and cannot reuse, and can cause a large amount of unnecessary wastes.
Utility model content
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of push-and-pull ring reusable high pressure injector.
For achieving the above object, this utility model provides following technical scheme: a kind of high pressure injector, comprise syringe body and push-and-pull ring, described syringe comprises injection tube and push rod, described push rod is plugged in injection tube, and described push rod is provided with operating portion away from one end of syringe, wherein: described push-and-pull ring below is provided with mount pad, described mount pad middle part offers the groove of operating portion adaptation, and described mount pad offers the hollow slots with push rod external diameter adaptation away from the one side of push-and-pull ring.
By adopting technique scheme, described push-and-pull ring is pegged graft by the groove on mount pad and the operating portion on push rod, what its effect of stepping down of hollow slots made that operating portion can be firm is plugged in mount pad, the push-and-pull ring arranging by being independent of push rod, reach the effect that push-and-pull ring can reuse, saved national resources.
This utility model is further set to: the cross section of described push rod is decussate texture setting, and the bottom land of described hollow slots is provided with the projection towards hollow slots opening part.
By adopting technique scheme, by described projection, being stuck in cross section is on criss-cross push rod, plays fixedly push-and-pull ring, prevents that push-and-pull ring from rotating the effect coming off.
This utility model is further set to: described projection is set to isosceles right triangle.
By adopting technique scheme, described triangular hill can better be stuck on push rod, further strengthens fixed effect.
This utility model is further set to: push-and-pull ring and mount pad are integral type setting.
By adopting technique scheme, described push-and-pull ring is easy to process and more firm by injection moulding integrated molding.
This utility model is further set to: described push-and-pull ring diameter is to being greater than 20 millimeters.
By adopting technique scheme, described push-and-pull ring can allow the thumb of user pass easily, avoids obese people to use, make the suitability of described push-and-pull ring wider, use convenient.
