Abstract
A destructing type disposable syringe is composed of a needle tube, a needle stand, a protecting cap, an outside sleeve, a core rod and a piston; the piston is mounted on the top of the core rod by sleeving; the core rod is installed in the outside sleeve; the needle stand and the needle tube are installed on the outside sleeve successively; and the protecting cap is covered on the needle stand. The syringe is characterized in that: a circular groove is formed on the central position of the hand pressing side of the core rod end; a tapered position-restricting step is formed on the upper portion of the circular groove; an additional sleeve segment is disposed on the end of the outside sleeve; the lower end of the additional sleeve segment is formed with a circular groove; and a tapered position-restricting step is formed on the lower portion of the circular groove. The syringe of the utility model has the advantages of simple structure, convenient operation and low cost; is suitable for various medical places; and achieves good economic benefit and social benefit.
Description
Technical field
This utility model relates to a kind of disposable use aseptic medical equipment, specifically is a kind of Single-Use Auto-Disable Syringes.
Background technology
Disposable syringe is a kind of disposable medical instrument consumptive material product, clinical at home extensive use.At present domestic disposable syringe generally has two kinds of plain edition and self-destruction typies.The plain edition syringe only has basic functions such as the extraction medicinal liquid of syringe and liquid medicine injection, and after the plain edition syringe used, its structure, shape were reused by bad personnel easily without any change, 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.
The utility model content
The purpose of this utility model provides a kind of simple in structure, Single-Use Auto-Disable Syringes that manufacturing procedure is few and easy to operate.
The technical solution of the utility model is: Single-Use Auto-Disable Syringes, form by needle tubing, needle stand, protective cap, overcoat, core bar, piston, described piston bush is contained in the core bar top, core bar is sleeved in the overcoat, the overcoat top is suit needle stand and needle tubing successively, also be covered with protective cap on the needle stand, it is characterized in that: described core bar end press annular groove of hands side intermediate open position, and this annular groove top has the limited step of a band tapering; Described overcoat end is set up one section stack shell, and this inboard, lengthening section stack shell lower end has an annular groove, and has the limited step of a band tapering below this annular groove.
The thickness of described lengthening section stack shell is greater than overcoat stack shell thickness.
Described core bar length equates with overcoat and lengthening section stack shell sum.
Described overcoat and lengthening section stack shell are the PP material, and core bar is the TPE material.
Overcoat of the present utility model and core bar all are provided with and cooperate tight limited step, and after finishing to patient infusion, core bar all is inserted in the overcoat, because the effect of limited step, core bar can not be extracted once more, reaches function of use once again.This utility model is simple in structure, easy to operate, with low cost, is fit to all kinds of medical spaces and uses, and has favorable economic benefit and social benefit.

The specific embodiment
Below in conjunction with accompanying drawing the technical solution of the utility model is described further, but protection domain of the present utility model is not limited in embodiment.
As shown in Figure 1, 2: Single-Use Auto-Disable Syringes, form by needle tubing 1, needle stand 2, protective cap 3, overcoat 4, core bar 5, piston 6.Piston 6 is sleeved on core bar 5 tops, and core bar 5 is sleeved in the overcoat 4, and overcoat 4 tops are suit needle stand 2 and needle tubing 1 successively, also is covered with protective cap 3 on the needle stand 2.With core bar 5 ends press hands 7 thickening, then this thickening by annular groove 9 of side intermediate open position of hands and above this annular groove 9, have the limited step of a band tapering.Set up one section stack shell 8 at common overcoat 4 ends, and the thickness of lengthening section stack shell 8 is greater than overcoat stack shell thickness, have an annular groove 10 in this inboard, lengthening section stack shell 8 lower end this moment, and have the limited step of a band tapering below this annular groove 10.
Core bar is by making the length of this core bar 5 equate with overcoat 4 and lengthening section stack shell 8 sums after the hand channel thickening.
Aforementioned overcoat 4 and lengthening section stack shell 8 are the PP material, and core bar 5 is the TPE material.
This utility model mainly is by the limited step of annular groove and band tapering is set on by hands and lengthening section stack shell, and both cooperatively interact, and can not extract the purpose that reaches self-destruction thereby realize core bar is fastened in the overcoat.
