Description
Technical field
This utility model belongs to medical instruments field, is specifically related to a kind of disposable use vaccine self-destruction syringe.
Background technology
Single-Use Auto-Disable Syringes belongs to disposable medical instrument consumptive material product, clinical at home extensive use.At present domestic Single-Use Auto-Disable Syringes generally has two kinds of plain edition and self-destruction typies.The plain edition self-destruction syringe only has basic functions such as the extraction medicinal liquid of self-destruction syringe and liquid medicine injection, and after the plain edition self-destruction syringe uses, its structure, shape are without any change, reused by bad personnel easily, virus spread, thus self-destruction syringe progressively is born and be extensive use of.Existing self-destruction syringe mainly is after injection is finished core bar to be fractureed or core bar is retained in the overcoat, these self-destruction syringe complex structures, operation trouble and inconvenient operation during injection moulding, and the medicinal liquid that overlaps medicine outlet one segment distance when medicinal liquids such as insulin injection, immune vaccine outside can not be injected fully, causes liquid waste.
The utility model content
The purpose of this utility model is to overcome the above-mentioned weak point that exists, provide a kind of simple in structure, easy to operate, can effectively avoid reusing and cause the disposable use vaccine self-destruction syringe of cross infection danger.
This utility model is that the achieve the above object technical scheme that adopted is as follows:
Disposable use vaccine self-destruction syringe; comprise protective sleeve, needle tubing, overcoat and core bar; described core bar top is with piston; described protective sleeve covers on the needle tubing, and the needle tubing lower end is connected the overcoat top, is set with core bar in the overcoat; the core bar lower end also is provided with banking stop; it is characterized in that described outer putting is provided with screens, core bar is provided with the corresponding card that cooperates with screens, also is provided with the self-destruction point on the core bar.
The point of self-destruction described in this utility model is one section easily broken connecting rod, and described card is positioned at self-destruction point top.
Described screens is circular projection, and is positioned on the outer casing inner wall.
This utility model is by being provided with screens on the coat and the card that matches with screens being set on core bar, when core bar is pushed into the card position, screens and the card stuck core bar that makes mutually can not shrink back, therefore effectively avoid reusing and cause the danger of cross infection, the safer convenience of aspiration medicinal liquid; Compare traditional syringe this utility model syringe less residue, make on pharmaceutical quantities more accurate.
The utlity model has the while simple in structure, easy to operate, cheap for manufacturing cost can effectively avoid cross infection, therefore is fit to promote the use of widely.
