Abstract
The utility model discloses an injector tail-hood and relates to the technical field of medical equipment, in particular to the structure of the injector tail-hood. The injector tail-hood comprises a cylindrical barrel-shaped body (1). A protruding edge (2) is connected with the outer side at the rear end of the barrel-shaped body (1). The protruding edge (2) is of a board-shaped structure and perpendicular to an axis of the barrel-shaped body (1). The left side and the right side of the protruding edge (2) are respectively provided with a boss (3). A circular arc-shaped concave way is arranged between the inner side of each boss (3) and the barrel-shaped body (1). The injector tail-hood solves the problems that when an existing injector is used, air enters a needle cylinder from the portion between a piston mandrel and the rear portion of the needle cylinder, an inner rubber plug can not keep balance, and therefore use is influenced.
Description
Technical field
This utility model relates to technical field of medical instruments, is specifically related to a kind of tail cover structure 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 to zone that other method can't approach 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.
Existing syringe in use, has air between piston core bar and syringe rear portion and enters syringe, and inner plug can not keep balance, the impact use.
The utility model content
This utility model provides the syringe tail-hood, and this utility model has solved existing syringe in use, have air between piston core bar and syringe rear portion and enter syringe, and inner plug can not keep balance, the problem that impact is used.
For addressing the above problem, this utility model adopts following technical scheme: the syringe tail-hood, comprise columniform cylindrical body 1, and cylindrical body 1 outside, rear end is connected with convex edge 2, and convex edge 2 is slab structures, and convex edge 2 is vertical with the axis of cylindrical body 1; There is boss 32 front sides, convex edge of left and right sides, between boss 3 inboards and cylindrical body 1, circular arc Ao road are arranged.
This utility model is set in the afterbody of injector syringe, and boss is stuck in the outer edge of injector syringe, and syringe piston rod passes from the hole of tail-hood, and this utility model can enter the effect of syringe by air-isolation, and makes inner plug keep balance.
The accompanying drawing explanation
Fig. 1 is this utility model structural representation.
Symbol description in figure: cylindrical body 1, convex edge 2, boss 3.
The specific embodiment
below with best embodiment, this utility model is described in detail
.
As shown in Figure 1, the syringe tail-hood, comprise columniform cylindrical body 1, and cylindrical body 1 outside, rear end is connected with convex edge 2, and convex edge 2 is slab structures, and convex edge 2 is vertical with the axis of cylindrical body 1; There is boss 32 front sides, convex edge of left and right sides, between boss 3 inboards and cylindrical body 1, circular arc Ao road are arranged.
Finally it should be noted that: obviously, above-described embodiment is only for this utility model example clearly is described, and is not the restriction to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without also giving all embodiments.And the apparent variation of being amplified out thus or change are still among protection domain of the present utility model.
