The utility model discloses simple structure, convenient to use, the push rod is drawn backward to the back of finishing using because the stopper can't return under the prevention of locator, when the pulling force exceed self -destruction convex body and push rod be connected power the time, the self -destruction convex body breaks away from with the push rod fracture, realizes the self -destruction, the user only can pull out the push rod, and inside the piston stays the cylinder, unable reuse, more unable realization recovery sale.
Description
Technical field
This utility model is related to a kind of type self-destroyed channel catfish medical fluid injector.
Background technology
Syringe is a kind of common medical instruments, mainly in order to liquid medicine injection or drawing liquid.Syringe is carried little by front end
The syringe in hole and matching piston core bar composition.Syringe be used for by a small amount of liquid or its be injected into other methods no
The close region of method or extract out from those places, when core bar is extracted, liquid or gas are inhaled from syringe front end aperture
Enter, when core bar pushes, liquid or gas are extruded, at present, need to use medical fluid injector in channel catfish culture experiment
Inject or feed experiment medicinal liquid or liquid bait, at present all using the plastic injector for temporary use medically commonly used, its shortcoming is such as
Under: reusable, shared, recovery is sold etc., is easily caused cross infection in channel catfish culture experiment, impact cultivation peace
Entirely, research and development safety self-destructing channel catfish medical fluid injector becomes the inexorable trend of production development.
Utility model content
The purpose of this utility model is to solve the deficiencies in the prior art, provides a kind of type self-destroyed channel catfish liquid medicine injection
Emitter.
This utility model solves its technical problem and be the technical scheme is that
Type self-destroyed channel catfish medical fluid injector, including syringe, push rod, piston and needle stand, described piston includes piston
Body and piston seat, piston seat includes limiting section, department of assembly and self-destruction portion, and piston only is removably connected to department of assembly, self-destruction
Portion is provided with least one pair of self-destruction convex body, and push rod is fixedly connected with self-destruction convex body, and the front end of described limiting section is fixed with stop,
Described syringe front end is provided with localizer, forward passes through for stop and stops stop from inversely being return, needle stand is connected in syringe
Front end.
This utility model structure is simple, easy to use, is located at localizer near the side of back end of syringe using front limit device,
Push rod is promoted, stop passes through localizer, in piston driving injecting liquid drug to fish body, after finishing, pulls back and push away during use
Bar, because stop cannot be return under the prevention of localizer, when pulling force exceedes the attachment force of self-destruction convex body and push rod, self-destruction
The fracture of convex body and push rod departs from, and realizes self-destruction, push rod only can be pulled out by user, and piston stay syringe internal it is impossible to
Recycling, more cannot realize reclaiming selling.
Preferably, type self-destroyed channel catfish medical fluid injector also includes Tip protection mechanism, described Tip protection mechanism
It is made up of cover body and elastic core element, cover body is socketed on outside elastic core element, elastic core element is socketed on syringe front end.
Preferably, described self-destruction portion is provided with uniform, symmetrical two pairs of self-destruction convex bodys.This design is the most reasonable, and product stability is more
Good, either push away or uniform force during pulling-pushing rod, safety is good.
Preferably, described stop is in cone, and the basal diameter of stop is 1.2-1.4 times of limiting section diameter, institute
State the positioning tooth that localizer is that a pair symmetrically arranged and forward end tilts.It is located at positioning tooth using front limit device after syringe
The side at end, promotes push rod during use, because stop is in cone, stop resistance when through positioning tooth is gradually increased,
The sensation that user can in need push harder against, whether be maloperation, can significantly avoid the probability of maloperation if easily discovering,
Avoid meaningless product rejection.
Preferably, the angle that described positioning tooth forward end tilts is 5-10 °.
Preferably, described stop, piston seat and push rod integrated injection molding, localizer and syringe integrated injection molding.
Integrated injection molding, processing is simple, stable and reliable product quality.
The beneficial effects of the utility model are: reasonable in design, and processing is simple, easy to use, can facilitate after use
Self-destruction, it is to avoid be reused or reclaim sale, can also preferably avoid the self-destruction using front maloperation simultaneously.
Brief description
Fig. 1 is structural representation of the present utility model.
In figure: 1, syringe, 2, push rod, 3, piston, 31, piston only, 32, piston seat, 4, needle stand, 5, stop, 6, fixed
Position device, 7, cover body, 8, elastic core element.
Specific embodiment
Below by specific embodiment, and combine accompanying drawing, the technical solution of the utility model is made further specifically
Bright.
Embodiment:
Type self-destroyed channel catfish medical fluid injector as shown in Figure 1, including syringe 1, push rod 2, piston 3 and needle stand 4, institute
State piston 3 and include piston only 31 and piston seat 32, piston seat 32 includes limiting section, department of assembly and self-destruction portion, piston only 31
It is removably connected to department of assembly's (as being socketed), self-destruction portion is provided with least one pair of self-destruction convex body, push rod 2 is fixing with self-destruction convex body even
Connect, the front end of described limiting section is fixed with stop 5, and described syringe 1 front end is provided with localizer 6, forward passes through for stop 5
And stoping stop 5 from inversely being return, needle stand 4 is connected in the front end of syringe 1.
Specific to the present embodiment, type self-destroyed channel catfish medical fluid injector also includes Tip protection mechanism, described syringe needle
Protection mechanism is made up of cover body 7 and elastic core element 8, and cover body 7 is socketed on outside elastic core element 8, and elastic core element 8 is socketed on syringe 1
Front end.
In the present embodiment, described self-destruction portion is uniform, be symmetrical arranged two pairs of self-destruction convex bodys, and described stop 5 is in cone, limit
The basal diameter of position device 5 is 1.2-1.4 times of limiting section diameter, and described localizer 6 is that a pair symmetrically arranged and forward end is inclined
Oblique positioning tooth, the angle that described positioning tooth forward end tilts is 5-10 °, described stop 5, piston seat 32 and push rod 2 one
Injection mo(u)lding, localizer 6 and syringe 1 integrated injection molding.
