The present invention relates to an injection needle cap having a reuse prevention structure, and more particularly, to an injection needle cap having a transparent open cap part and a fixed cap part integrally formed in a connection cut part, And a needle cap for preventing the reuse of the needle can be prevented by allowing the transparent cap part to be separated from the fixed cap part by cutting so as to confirm whether the needle is used according to whether or not the needle is cut, .

In general, a syringe is one of medical supplies, and is used for various purposes such as injecting injection liquid, collecting blood, or taking a sample.

Such a syringe includes a syringe body, a piston inserted into the syringe body, and a piston rod that pressurizes the piston. Depending on the use of the syringe, a syringe needle may be coupled to an upper discharge port of the syringe body, Or a combination of blood collecting tools.

Such a syringe must be discarded after one use to prevent reuse of the syringe because once the syringe is used, the patient's blood remains on the syringe needle and if the syringe containing the blood stain is used again, The pathogens contained in the virus are transferred to other people as they are, and secondary infection is caused by the transferred pathogens.

Accordingly, the syringe used once is discarded so that it can not be reused. However, in some cases, the syringe used for reducing the purchase cost of the syringe is frequently used without being discarded, It is a social problem caused by infection as well as infection by radio waves.

In recent years, disposable syringes have been used which make it impossible to reuse syringes after they have been used. Such disposable syringes can improve the structure of the syringe itself so that it can be checked whether the syringe is used or not, have.

However, the conventional disposable syringe has a structure which can not be applied to a general syringe, so that a disposable syringe must be separately manufactured and used.

In this conventional technique, when the rotating body enclosing the needle portion is pressed, the needle portion is not exposed to the outside and can not be reused because the needle portion is lowered and raised by the elastic force and is not lowered again due to the fixing protrusion.

However, in the case of the related art, there is a problem in that productivity is deteriorated as well as assemblability because the components are complicated, and when the elasticity of the gimbal member is deteriorated or bad, the needle is not exposed.

As another example, there has been disclosed a reuse prevention injection needle which is a public office 20-1990-0009317, which has a groove formed in an outlet protruding from a syringe and having a plurality of cutout grooves and an inner circumferential groove formed in a cap in which a needle is formed And an inclined circumferential groove of an annular yarn inside the cap, and a plurality of sets of cut-outs are formed or formed on the outer periphery of the cap.

Such a conventional technique has a simple structure so that it is easy to handle and use. However, since the injection needle is exposed to the outside before use, contaminants are injected into the injection needle and the injection needle is contaminated.
