An object of the present invention is to provide an injection needle corruption apparatus and method of injection needle assembly. A needle breakage devices of the injection needle assembly according to the present invention is a device for breaking the injection needle mounted to a hub of the needle assembly, inlet for introduction of the injection needle a formed body to be incorporated in the main body includes a gear with the installed drive gear and the driven gear so as to rotate engaged to pass the injection needle is introduced into inlet and gears By needle passing between is broken is taken out from the hub, as compared to the grinding section having a sharp edge for crushing as in the prior art, the gear is usable permanently separated waste of can waste a large number of injection needle is very small capacity volume, injection needle from the needle assembly is completely removed, the majority of the conventional injection needle that the remaining part of the injection needle to needle assembly It is a very safe than the separation or removal device, in corruption device small, constant power, easily installed in a hospital with a small configuration space because it can be manufactured in such as rechargeable battery or power supply of batteries, for portable is easier animal husbandry there is a feature that is good usability even farmers. .BACKGROUND 4【課題】注射針組立体の注射針破損装置及びその方法を提供する。【解決手段】本発明による注射針組立体の注射針破損装置は、注射針組立体のハブに装着された注射針を破損するための装置であって、注射針の投入のための投入口が形成された本体と、本体に内蔵され、投入口に投入される注射針を通過させるためにかみ合って回転するように設置された駆動歯車及び従動歯車を備えた歯車と、を含み、そして歯車の間を通過する注射針がハブから取り出されて破損されることによって、従来のように破砕するための鋭い刃を有する粉砕部に比べて、歯車は永久的に使用可能で、分離された廃棄物の容量体積が非常に小さくて多数の注射針を廃棄でき、注射針組立体から注射針が完全に除去され、注射針組立体に注射針の一部が残存する大部分の従来の注射針の分離または除去装置よりも非常に安全であり、破損装置が小型で、常時電源、充電池または乾電池の電源などで製作できるため配置空間が小さくて病院に設置しやすく、持ち運びが楽であるため畜産農家でも使い勝手がよいという特徴がある。【選択図】図4
