PROBLEM TO BE SOLVED: To provide a protective connection device to be connected to a medical device in a hygienic and safe state.SOLUTION: The present invention relates to a medical transfer/connection device including an external component, an internal component is telescopically disposed in the external component, and the internal component with a barrier member is so configured that the barrier member is axially movable between a shielding position and a cleaning position in the external component, and, when the barrier member (12) is in the shielding position, an end-part opening is opened to receive one of a first medical device and a second medical device. A first end of the internal component forms a first end of the medical transfer/connection device, and a second end of the external component forms a second end of the medical transfer/connection device. After the first end coupled with one of the first medical device and the second medical device, the second end can be coupled with the other one of the first medical device and the second medical device, where the other one of the first medical device and the second medical device includes a puncture member.SELECTED DRAWING: Figure 3【課題】衛生的かつ安全な状態で、医療器具に接続するための保護接続装置の提供。【解決手段】本発明は、外側部品を備える医療用移送接続装置に関連し、内側部品は、外側部品に入れ子式に配置され、バリア部材を有する内側部品は、外側部品において、バリア部材が遮蔽位置と、洗浄位置との間で軸方向に可動であり、バリア部材(12)が遮蔽位置にあるときに端部開口が開いて第1の医療器具および第2の医療器具の一つを受け入れ、内側部品の第1の端部は、医療用移送接続装置の第1の端部を形成し、外側部品の第2の端部は、医療用移送接続装置の第2の端部を形成し、第1の端部が第1の医療器具および第2の医療器具の一つと連結した後に、第2の端部が第1の医療器具および第2の医療器具の他の一つと連結することができ、第1の医療器具および第2の医療器具の他の一つが穿刺部材を備える。【選択図】図3
