The present invention weight can be greatly reduced, to the outer surface of the cylindrical body of the dialyzer and the like in the mounted state The display described can be easily visually recognized, and provides a medical instrument holder. A holder for the medical device 1 includes a holding portion A having a pair of pinching members 4 and 5 sandwiching the cylindrical main body 2a elastically, together with the holding part is coupled, the holder And a clamp portion B that can be held at a predetermined height of the pole stand 3. Clamping portion, and the outer threaded portion is formed a cylindrical wall portion, an opening can Tsu pole 3a by notching a portion from the edge portion axially opposite directions of the wall, the cylindrical wall formed on the bottom surface with a positioning portion for one side of the pole is pressed against the connecting member provided with, is guided in the axial direction of the wall portion, a pressing member for pressing the other side of the pole, is screwed to the outer circumferential screw portion the inner circumferential screw portion provided, and a clamp operation member 7 for pressing the pressing member to the pole by turning operation. The clamping operation member is affixed to the inside of the wall, the backup portion is provided having an outer surface for preventing a deformation of the wall.BACKGROUND 1【課題】重量を大幅に低減でき、装着状態でダイアライザー等の筒状本体の外面に記載された表示を容易に視認することができる、医療器具用ホルダを提供する。【解決手段】医療器具用ホルダ1は、筒状本体2aを弾性的に挟持する一対の挟持部材4,5を有する保持部Aと、保持部が連結されるとともに、保持部をポールスタンド3の所定高さで保持できるクランプ部Bとを備える。クランプ部は、外周螺子部が形成された円筒状の壁部と、壁部の対抗する一部を縁部から軸方向に切り欠いてポール3aを通挿できる開口部と、円筒状の壁部の底面に形成されてポールの一側が押し付けられる位置決め部とを設けた連結部材と、壁部の軸方向に案内され、ポールの他側を押圧する押圧部材と、外周螺子部に螺合される内周螺子部が設けられ、回動操作することにより押圧部材をポールに押圧するクランプ操作部材7とを備える。クランプ操作部材には、壁部の内側に添着されて、壁部の変形を阻止する外面を有するバックアップ部が設けられている。【選択図】図1
