Description
Technical field
This utility model relates to a kind of structure of syringe, and particularly a kind of disposable syringe with safety self-destruct function belongs to technical field of medical instruments.
Background technology
Disposable syringe is widely used in medical field, has avoided using unhygienic syringe and the viral cross infection that produces.But common disposable syringe has the possibility of being used by secondary, causes some medical institutions' violation operation.Because the ordering about of economic interests, common disposable syringe is used by secondary, even nonexpondable phenomenon often has generation, causes viral cross infection easily.Therefore, designing a kind of disposable syringe that the safety self-destruct function is arranged, stop disposable syringe by the possibility that secondary uses, is the urgent needs in market.
The utility model content
The purpose of this utility model is exactly for satisfying the demand in market, designing a kind of safety self-destruct disposable syringe.This syringe can reach the pumpback needle tubing, and the disposable use of safety self-destruct cross infection can not take place, and product is easy to manufacture, cheap.
The purpose of this utility model is to realize like this, the safety self-destruct disposable syringe, comprise the intravital injection core rod of injection cylinder and injection tube, injection core rod is made up of the interconnective body of rod and bar head, the front end of injection cylinder is installed and is connected needle holder, the liquid-through hole of the center of needle holder for connecting, the bonding installation needle tubing in the top of needle holder, on the bar head of injection core rod plug is installed, the liquid-through hole bottom that it is characterized in that described needle holder center is provided with the button neck, nose is provided with elasticity and locks button in, elasticity is locked the internal diameter of the external diameter of button greater than the button neck in, be provided with junction point between bar head and the body of rod and be connected, cylinder back-end is provided with the retaining ring, and the internal diameter of retaining ring is less than the external diameter of bar head.
Described body of rod rear end is provided with the lamellar safety plate, adopts junction point to be connected between the body of rod and the lamellar safety plate.
Described junction point is a thin footpath joint pin.
Described barrel front end is provided with step and the boss that the positioning needle headstock is installed.
Safety self-destruction disposable syringe, earlier safety plate is removed the absorption medicinal liquid before using, in the use injection core rod is advanced into the front portion of injection cylinder, the elasticity of bar head is locked button in and is entered into the interior button throat of needle holder center liquid-through hole, the button neck is locked elasticity in padlock and is lived and can not fall back, pull back injection core rod this moment, the bar head is to cylinder back-end retaining ring place, make junction point 9 fractures, the bar head that comprises plug, needle tubing is stuck and stays in the injection cylinder, injection cylinder and injection core rod all can not be used again, reach the purpose of safety self-destruct.Safety plate is established in the body of rod rear end of safety self-destruct disposable syringe, and effect is: 1, when syringe uses, must get rid of safety plate, could shift injection core rod onto the end, make liquid medicine injection all inject human body.2, prevent before completed knocked down products and syringe use misoperation and being taken place by the phenomenon of self-destruction.3, can make user clearly discern syringe and whether be used, prevent that syringe from being used by secondary.
This utility model is rational in infrastructure simple, manufactures easily, and cost is low.This syringe can reach the pumpback needle tubing, and the disposable use of safety self-destruct guarantees safe in utilizationly, avoids syringe to cause viral cross infection because of repeated use.
