Disclosed is no risk that the contact used needle directly being contaminated and to provide a more needle remover less biological hazards A needle removal device, as well as configured to communicate erected needle on opening of the used needle housing case, a needle Dakkyo cylindrical body 13 formed with an inner circumferential wall to the helical surface 26 , along with the configured to loosely fitted screwed on the outer peripheral surface by Nishigojo section 32 to the inner peripheral wall spiral surface of the needle Dakkyo cylinder, integrally needle hub 44 while accommodating the needle tube 45 of the internal to the injection needle 11 I includes a needle Dakkyo frame body 14 and can be mounted to,. The syringe 10 with attached needle body Dakkyo piece needle portion is inserted into the body needle Dakkyo cylinder, by a needle Dakkyo frame member to pivot sliding needle is Dakkyo. Needle Dakkyo piece body, fall to needle the held was still spent needle housed inside the case after Dakkyo of injection needle [Selection Figure Figure 7【課題】使用済み注射針と直接接触して汚染されるおそれのない、より生物学的危害要因の少ない注射針除去装置を提供する。【解決手段】注射針除去装置は、使用済針収容ケースの針投入用開口部に立設して連通するように構成すると共に、内周壁を螺旋面26に形成した針脱去筒体13と、螺合条部32により針脱去筒体の内周壁螺旋面に外周面で遊嵌螺合するように構成すると共に、内部に注射針11の針管45を収容しつつ針基44を一体に装着可能とした針脱去コマ体14と、を備える。針脱去コマ体を注射針部分に装着した注射器10を針脱去筒体内に挿入し、針脱去コマ体を旋回摺動させることにより、注射針が脱去される。針脱去コマ体は、注射針の脱去後に注射針を保持したまま使用済針収容ケース内へ落下する。【選択図】図7
