Abstract
The utility model relates to a disposable self-destructive syringe in medical instruments. The disposable self-destructive syringe comprises a needle, a protective cap, an outer sleeve and a core rod, the needle is covered by the protective cap, and is mounted on the top of the outer sleeve, the core rod is mounted in the outer sleeve, a piston is mounted on the top of the core rod, and the disposable self-destructive syringe is characterized in that the liquid outlet of the outer sleeve is provided with an inwardly projected puncture head. The disposable self-destructive syringe has the advantages of simple structure, low cost and the like, and moreover, the disposable self-destructive syringe can be produced on an automatic production line completely, and therefore is suitable for wide application.
Description
Technical field
This utility model belongs to medical instruments field, is specifically related to a kind of Single-Use Auto-Disable Syringes.
Background technology
Single-Use Auto-Disable Syringes is a kind of disposable medical instrument consumptive material article, 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 extraction medicinal liquid and the liquid medicine injection of self-destruction syringe; And after the plain edition self-destruction syringe uses; Its structure, shape have no change; Reused by bad personnel easily, virus spread, thus self-destruction syringe progressively is born and be widely used.The existing formula syringe of ruining mainly is after injection is accomplished, 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.
The utility model content
The purpose of this utility model is the deficiency that overcomes above-mentioned existence, and a kind of simple in structure, easy to operate Single-Use Auto-Disable Syringes is provided.
The technical scheme that this utility model is adopted to achieve these goals is:
Single-Use Auto-Disable Syringes; It comprises needle tubing, helmet, overcoat and core bar; Said helmet covers on above the needle tubing, and needle tubing is sleeved on the overcoat top, and the overcoat internal sleeve is equipped with core bar; Said core bar top is set with piston, it is characterized in that said overcoat liquid outlet is provided with inwardly protruded puncturing head.
According to the described Single-Use Auto-Disable Syringes of this utility model, it is characterized in that the cross section of said core bar is ' ten ' font.
This syringe jacket is the same with the conventional syringe overcoat, and a tip is just arranged in the pin holes lower end, after piston and the core bar assembling; The wall footpath of piston upper end is very thin, after injecting fluid is accomplished, utilizes the tip of overcoat the inside to puncture the plane of piston upper end; Core bar is cylindrical; The inside is empty, after piston breaks, can not reuse.Because breaking of piston can't aspiration medicinal liquid, can leak gas, core bar promotes forward also can't reach reusable function simultaneously, and simple in structure, with low cost, reaches automatic production line production fully, therefore is fit to be widely used.
Description of drawings
Fig. 1 is this utility model structural representation
Among the figure: 1-needle tubing, 2-helmet, 3-overcoat, 4-core bar, 5-puncturing head.
The specific embodiment
Further specify below in conjunction with the technical scheme of accompanying drawing this utility model;
As shown in Figure 1: Single-Use Auto-Disable Syringes, it comprises needle tubing 1, helmet 2, overcoat 3 and core bar 4, and said helmet 2 covers on above the needle tubing 1, and needle tubing 1 is sleeved on overcoat 3 tops, and overcoat 3 internal sleeve are equipped with core bar 4, and said core bar 4 tops are set with piston.Said overcoat 3 liquid outlets are provided with inwardly protruded puncturing head 5.The cross section of said core bar 4 is ' ten ' font.This syringe jacket is the same with the conventional syringe overcoat, and a tip is just arranged in the pin holes lower end, after piston and the core bar assembling; The wall footpath of piston upper end is very thin, after injecting fluid is accomplished, utilizes the tip of overcoat the inside to puncture the plane of piston upper end; Core bar is cylindrical, and the inside is empty, after piston breaks; Can not reuse, reach the purpose of self-destruction.
