PROBLEM TO BE SOLVED: To provide a medical device for transporting at least two medicaments from individual reservoirs.SOLUTION: An administration interface 500 comprises a first one way valve 508, a second one way valve 510, a first medicine valve front ullage 504, a second medicine valve front ullage 506, a post valve ullage 512 having a first end part 516 and a second end part 518 and a needle 406. The first medicine valve front ullage is connected to the post valve ullage by the first one way valve and the second medicine valve front ullage is connected to the post valve ullage by the second one way valve. First fluid may be guided from the first medicine valve front ullage to the post valve ullage and second fluid may be guided from the second medicine valve front ullage to the post valve ullage. It is so designed that a first end part of the needle is inserted into the post valve ullage and the post valve ullage allows reverse flow between the post valve ullage and the needle.SELECTED DRAWING: Figure 13 【課題】別個のリザーバから少なくとも２つの薬物を送達するための医療デバイスを提供する。【解決手段】投薬インターフェース５００は、第１の一方向弁５０８と第２の一方向弁５１０と第１の薬剤弁前アレージ５０４と第２の薬剤弁前アレージ５０６と第１の端部５１６および第２の端部５１８を有する弁後アレージ５１２と針４０６とを備える。第１の薬剤弁前アレージは、第１の一方向弁によって弁後アレージに連結され、第２の薬剤弁前アレージは、第２の一方向弁によって弁後アレージに連結される。第１の流体を第１の薬剤弁前アレージから弁後アレージに案内可能であり、第２の流体を第２の薬剤弁前アレージから弁後アレージに案内可能である。針の第１の端部が弁後アレージ内に挿入され、弁後アレージは弁後アレージと針の間で流れ反転があるように設計される。【選択図】図１３
