Description
Technical field
This utility model relates to disposable use aseptic medical equipment, specifically is to be specially adapted to liquid medicine injection or configuration medicinal liquids such as human body is subcutaneous, muscle, vein.
Background technology
Single-Use Auto-Disable Syringes is a kind of disposable medical instrument consumptive material product, clinical at home extensive use.At present domestic a kind of self-destruction syringe of disposable use generally has two kinds of plain edition and self-destruction typies.A kind of self-destruction syringe of plain edition only has basic functions such as a kind of extraction medicinal liquid of self-destruction syringe and liquid medicine injection, and after a kind of self-destruction syringe of plain edition uses, its structure, shape are without any change, reused by bad personnel easily, virus spread, thus type self-destroyed a kind of self-destruction syringe progressively is born and be extensive use of.Existing type self-destroyed a kind of self-destruction syringe mainly is after injection is finished core bar to be fractureed or core bar is retained in the overcoat, these type self-destroyed a kind of self-destruction syringe complex structures, operation trouble and inconvenient operation during injection moulding.
The utility model content
The purpose of this utility model provides a kind of self-destruction syringe that is specially adapted to liquid medicine injection such as human body is subcutaneous, muscle, vein or configuration medicinal liquid.
The technical scheme that this utility model adopted is: a kind of self-destruction syringe, comprise core bar, overcoat and needle tubing, described core bar is sleeved in the overcoat, overcoat top suit needle tubing, it is characterized in that: described core bar rear portion is provided with the self-destruction card, and described overcoat inner tubal wall rear portion is provided with the self-destruction groove that matches with the self-destruction card.
Also be provided with bayonet socket described in this utility model on the core bar, and after this bayonet socket is positioned at the self-destruction card.
This utility model is specially adapted to liquid medicine injection or configuration medicinal liquids such as human body is subcutaneous, muscle, vein, and self-destruction is simple to operate.Secondly this syringe construction is simple, easy to use, the injection moulding operation is simple and with low cost, is fit to various medical spaces and uses, and has certain economic benefits.
Description of drawings
Fig. 1 is this utility model structural representation
Among the figure: the 1-core bar; The 2-overcoat; The 3-needle tubing; 4-self-destruction card; 5-self-destruction groove; The 6-bayonet socket.
The specific embodiment
Below in conjunction with accompanying drawing the technical solution of the utility model is described further:
As shown in Figure 1: self-destruction syringe, comprise core bar 1, overcoat 2 and needle tubing 3, described core bar 1 is sleeved in the overcoat 2, overcoat 2 top suit needle tubings 3, described core bar 1 rear portion is provided with self-destruction card 4, and described overcoat 2 inner tubal wall rear portions are provided with the self-destruction groove 5 that matches with self-destruction card 4.Also be provided with bayonet socket 6 on the described core bar 1, and after this bayonet socket 6 is positioned at self-destruction card 4.The maximum pull conformance with standard YZB/ state 0107-2002 self-destructed disposable that this bayonet socket 6 can bear uses asepsis injector.
This utility model by the core bar rear portion the self-destruction card and the self-destruction groove fit at overcoat rear portion, after injection is finished, core bar is located locked within overcoat, pull at and core bar can not be pulled out in overcoat.If pull core bar, core bar bayonet socket place reaches certain pulling force (conformance with standard YZB/ state 0107-2002 self-destructed disposable uses asepsis injector), and rupturing automatically in the core bar rear portion, causes syringe not reuse, thereby reach the self-destruction purpose.
Claims (2)
