PROBLEM TO BE SOLVED: To provide a clamp device which reduces time loss and physical burden of a nurse to the minimum by eliminating the need for turning a rotatable knob continuously for several times while supporting an infusion apparatus when fixing and detaching the infusion apparatus to and from a pole of an infusion stand.SOLUTION: The clamp device 20 switches a holding condition and holding released condition with respect to the pole 30 of the infusion stand. The clamp device includes a cylindrical screw member 2 which has a screw section on its inner surface and through which a main axis is inserted, a pair of male screw pieces 4 and 4 which is housed within a main axis receiving section in such a way that the pieces can switch an engaged condition and an engagement released condition with respect to a female screw section, and an operation means 103 having an operation section 3f which is arranged movably between a separated position and an operating position where the operation section is operated to move toward the rotary knob, and disengages the pair of male screw pieces into the engagement released condition.COPYRIGHT: (C)2010,JPO&INPIT【課題】輸液装置を輸液スタンドのポールに固定およびポールから取り外すときに、輸液装置を支えた状態で、回転ノブを何回転も回し続ける必要がなく、看護士の時間的損失と肉体的負担を最小限に抑えるクランプ装置の提供。【解決手段】輸液スタンドのポール30に対する把持状態または把持解除状態にするクランプ装置20であって、ネジ部をその内周面に形成し、かつ主軸体を挿通する筒状ネジ部材2と、雌ネジ部に対する歯合状態と歯合解除状態とになるように主軸体の収納部に内蔵されるとともにガイド部を有した一対の雄ネジ駒4、4と、回転ノブに向けて移動操作される操作位置と離間位置との間で移動可能に配置され、一対の雄ネジ駒を歯合解除状態にする操作部3fを有した操作手段103を備える。【選択図】 図5
