PROBLEM TO BE SOLVED: To provide an injector assist tool having improved operability and configured to safely perform self-injection.SOLUTION: The injector assist tool attached to an injector including a cylindrical barrel to be filled with parenteral injection, an injector body having an injection needle provided at one end in an axial direction of the barrel, and a cap mounted on the injector body to cover the injection needle, comprises a housing capable of extracting/inserting the injector body in an extraction/insertion direction orthogonal to the axial direction of the barrel a removal member for removing the cap from the injector body inserted into the housing a removal regulation part for regulating the removal of the injector body from the housing and an operation part that can be raised/tilted with respect to the housing. The removal member and the removal regulation part are operated along with raising operation/tilting operation of the operation part with respect to the housing.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2018,JPO&INPIT【課題】 操作し易く且つ安全に自己注射を行うことができる注射器補助具を提供することを課題とする。【解決手段】 注射剤が充填される筒状のバレル及び該バレルの軸線方向における一端に設けられる注射針を有する注射器本体と、該注射針を覆うようにして該注射器本体に装着されるキャップとを備える注射器に取り付けられ、バレルの軸線方向に直交する抜差方向で注射器本体を抜差可能な筐体と、該筐体に差し込まれた注射器本体からキャップを取り外す取外部材と、注射器本体の筐体からの抜き取りを規制する抜取規制部と、筐体に対して起倒可能である操作部とを備え、該操作部の筐体に対する引起操作及び押倒操作に伴って、取外部材と抜取規制部とを作動させる。【選択図】図1
