PROBLEM TO BE SOLVED: To provide a medical needle device which keeps the size of the blade section minimized, and at the same time, which can hold an injection needle by a sufficient force without specially providing a complicated mechanism.SOLUTION: This medical needle device is equipped with a needle base section 10 the distal end section 10a of which is fitted with an injection needle 11, and a sheath section 50 which is fitted on the needle base section 10, and at the same time, bonded with wing sections 51 and 52, has an approximately cylindrical shape, and is gripped by being pinched with fingers during a piercing operation. Holes 55 and 56 are provided at positions on both side surfaces of the sheath section 50 which are pinched with fingers, and thus, the movement of the sheath section 50 in the rotational direction and the movement of the needle base section 10 in the extensional direction are stopped by transmitting the gripping force to the needle base section 10 during the piercing operation.COPYRIGHT: (C)2008,JPO&INPIT【課題】翼部の大きさを最小限にするとともに、特に複雑な機構を設けることなく、注射針を十分な力で保持することのできる医療用針装置を提供する。【解決手段】先端部10aに注射針11が装着された針基部10と、該針基部10に外挿されるとともに翼部51,52が結合された略円筒状で、穿刺操作時に指で摘んで把持される鞘部50と、備え、前記鞘部50の指で摘まれる両側面の位置に穴55,56をあけて、前記穿刺操作時に把持力を前記針基部10に伝えて針基部10に対する前記鞘部50の回転方向及び針基部10の延びる方向への移動による動きを阻止した。【選択図】図1
