PROBLEM TO BE SOLVED: To relax a pain when pricking and pulling a needle with a simple configuration.SOLUTION: A device for relaxation of injection pain includes: a holder 6 storing a syringe 1, having engagement parts 6e on the periphery, and having a first hole 6a for passing the needle 1d at one end a guide member 10 installed movably in the axial direction on one end side of the holder, having engaged parts 10d engaging with the engagement parts 6e, and having a second hole 10c for passing the needle 1d in the center and an elastic member 3 interposed between the guide member 10 and one end of a holder 2, and energizing the second hole to a direction separated from the first hole. The engagement between the engagement parts 6e and the engaged parts 10d guides movement of the guide member 10. A grip member 8 rotatably supporting the holder 6 is installed to the holder 6, the guide member 10 is formed in a tube body 10 fitting on the periphery of the holder, a movement track B of the engaged parts 10d by the engagement parts 6e is inclined to the center line of the axial direction of the holder, and a cylinder 1a is elastically supported to the holder 6.COPYRIGHT: (C)2012,JPO&INPIT【課題】簡単な構成で注射針を刺すときと抜くときの痛みを緩和させる。【解決手段】注射器1を収容して外周に係合部6eを有して一端に注射針1dを通す第一孔6aを有するホルダ6と、ホルダの一端側に軸方向に移動自在に装着され、係合部6eに係合する被係合部10dを有して中央に注射針1dを通す第二孔10cを有する案内部材10と、この案内部材10とホルダ2の一端との間に介在して第二孔を第一孔から離脱する方向に付勢する弾性部材3とを有し、係合部6eと被係合部10dとの係合で案内部材10の移動を案内した。また、ホルダ6に、ホルダ6を回転自在に支持する把持部材8を取り付け、案内部材10をホルダの外周に嵌合する筒体10とし、係合部6eによる被係合部10dの移動軌跡Bをホルダの軸方向の中心線Aに対して傾斜させ、且つシリンダ1aをホルダ6に弾性支持するものとした。【選択図】図5
