Description

Single-Use Auto-Disable Syringes
Technical field
This utility model belongs to medical instruments field, is specifically related to Single-Use Auto-Disable Syringes.
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 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.The existing formula syringe of ruining 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 is to solve existing syringe construction complexity, and technical problems such as trivial operations provide a kind of simple in structure, easy to operate Single-Use Auto-Disable Syringes.
This utility model is that the achieve the above object technical scheme that adopted is as follows:
Single-Use Auto-Disable Syringes, comprise core bar, overcoat, needle stand needle tubing and helmet, described helmet covers on the needle tubing, needle tubing is fixedlyed connected with needle stand and is integral and is sleeved on the overcoat top, be set with the core bar of band piston in the overcoat, it is characterized in that described core bar is provided with self-destruction section and ratchet, put outward and be provided with the corresponding snap ring that cooperates with ratchet.
The section of self-destruction described in this utility model is divided into upper and lower two parts for the connecting rod of thin weak point and frangibility and with core bar.
Described ratchet is located at the upper end of self-destruction section.
Described snap ring is arranged on around the inwall of overcoat crimping.
Described snap ring is an annular groove.
This utility model is by being provided with self-destruction section and ratchet on core bar, on the inwall of overcoat crimping, be provided with and ratchet corresponding annular groove snap ring, therefore when liquid medicine injection, when the core bar top reaches in the overcoat top and is about to medicinal liquid and all releases, ratchet on the core bar reaches the snap ring position just and is stuck in the snap ring and can not extract, and reaches the purpose of self-destruction.
This utility model is simple in structure, easy to operate, cheap for manufacturing cost, is fit to promote the use of widely.
