Abstract
The invention relates to a syringe. The syringe comprises a syringe push rod and a syringe tube which are matched, an annular elastic buckle is arranged at the rear end of the syringe push rod, the rear end of the outer end face of the buckle is a columnar surface, and the front end of the buckle is a conical surface gradually reduced towards the front caliber; and the rear end of the syringe tube is provided with a locking cavity matched with the elastic buckle, an elastic clamping pad attached to the locking cavity is arranged in the locking cavity, the caliber of the rear end of the locking cavity is equivalent to that of the columnar surface of the buckle, the caliber of the contact part of the front end of the locking cavity and the conical surface of the buckle is greater than that of the columnar surface of the buckle, and an elastic clamping ball attached to the locking cavity is arranged between the contact parts of the locking cavity and the buckle. The syringe can only reach one-time injection stroke, is automatically locked after the one-time injection stroke is finished, cannot be reused, and is natural, smooth, scientific and perfect.
Description
Technical field
The present invention relates to a kind of syringe, belong to technical field of medical instruments.
Background technology
Big of existing disposable syringe as artificially not damaging, can also carry out repeatedly (but several times) injection stroke in injection stroke completion for the first time, and patient is prone to produce cross infection and malpractice, has strengthened medical-risk.For this reason for fear of this kind risk, the also syringe of property use once, its version is also varied, but mostly has complex structure, uses defectives such as inconvenience, needs further to improve.
Summary of the invention
The present invention is directed to above-mentioned defective, purpose is to provide a kind of re-use preventing once-used syringe simple in structure, easy to use.
Technical scheme of the present invention is: the injector push-rod and the injector cartridge that the present invention includes cooperation; It is characterized in that; A cyclic spring buckle is established in the injector push-rod rear end, and rear end, buckle outer face is a cylindroid, and front end is a diminishing taper surface of bore forward; The injector cartridge rear end is provided with the latch well that cooperates with Elastic buckle; Establish the elasticity card pad that is attached on the latch well in the latch well; Elasticity card pad rear end bore is suitable with buckle cylindroid bore; Elasticity card pad front end and buckle taper surface contact site bore are greater than the buckle cylindroid, and elasticity card pad front end is provided with inwardly outstanding formation projection closely to contact with taper surface with buckle taper surface contact site.
Advantage of the present invention is: the present invention guarantees to reach a shot and uses stroke, automatically locks after once using injection stroke to accomplish, and can not carry out second time again and use, and is natural and tripping, the science perfection.

The specific embodiment
The present invention includes the injector push-rod 2 and injector cartridge 1 of cooperation, a cyclic spring buckle 6 is established in injector push-rod 2 rear ends, and rear end, buckle 6 outer face is a cylindroid, and front end is a diminishing taper surface of bore forward; Injector cartridge 1 rear end is provided with the latch well 3 that cooperates with Elastic buckle 6; Establish the elasticity card pad 5 that is attached on the latch well 3 in the latch well 3; Elasticity card pad 5 rear end bores are suitable with buckle 6 cylindroid bores; Elasticity card pad 5 front ends and buckle 6 taper surface contact site bores are greater than buckle 6 cylindroids, and elasticity card pad 5 front ends are provided with inwardly outstanding formation projection 4 closely to contact with taper surface with buckle 6 taper surface contact sites.
Work process of the present invention is: 1) pull back push rod 2, re-use preventing once-used syringe at first sucks medicinal liquid when using, and waits when sucking scheduled volume; Syringe needle upwards is provided with; Flick syringe, push away push rod 2 forward slightly then, realize aerofluxus; After can suck demarcate the dosage medicinal liquid according to practical situation, get into inject state; 2) inject love dart push rod 2 forward; The taper surface of buckle 6 front ends at first gets into injector cartridge 1, and is less because of its bore, gets into easily and at first contacts with projection 4; In contact process; Projection 4 can produce an inside extruding force to taper surface, makes the cylindroid bore of Elastic buckle 6 slightly necessarily dwindle relatively, makes Elastic buckle 6 in latch well 3, to get into; 3) when operator try push rod 2 toward post-tensioning; This moment, projection 4 meetings produced an outside extruding force to buckle 6 taper surfaces; The bore of Elastic buckle 6 cylindroids is increased, make the cylindroid of Elastic buckle 6 and latch well 3 form interference fit, thereby can't push rod 2 extracted and be locked in injector cartridge 1; Inhale medicine so syringe can not carry out secondary, realized the purpose that Disposable, self-destroying uses.
Claims (1)
1. novel re-use preventing once-used syringe comprises the injector push-rod and the injector cartridge of cooperation it is characterized in that a cyclic spring buckle is established in the injector push-rod rear end that rear end, buckle outer face is a cylindroid, and front end is a diminishing taper surface of bore forward; The injector cartridge rear end is provided with the latch well that cooperates with Elastic buckle; Establish the elasticity card pad that is attached on the latch well in the latch well; Elasticity card pad rear end bore is suitable with buckle cylindroid bore; Elasticity card pad front end and buckle taper surface contact site bore are greater than the buckle cylindroid, and elasticity card pad front end forms projection closely to contact with taper surface with buckle taper surface contact site is inwardly outstanding.
