Zusammenfassung:To provide insertion mechanisms for drug delivery pumps, drug delivery pumps with safety integrated insertion mechanisms, methods of operating such devices, and methods of assembling such devices.SOLUTION: An insertion mechanism for a drug pump includes a housing 202, a sleeve 220, a rotational biasing member 210 initially held in an energized state, a retraction biasing member 216, and a hub 212 connected to a proximal end of a needle 214. The retraction biasing member is held initially in an energized state between the hub and the sleeve. The needle is inserted into a target tissue by the rotational biasing member and interaction between the hub and the housing. Retraction of the needle is caused by decompressing or de-energizing of the retraction biasing member. A drug delivery pump includes an activation mechanism, a drive mechanism, a sterile access connection, and the insertion mechanism.SELECTED DRAWING: Figure 8B 【課題】薬物送達ポンプ用の挿入機構、安全一体化式挿入機構を有する薬物送達ポンプ、こうしたデバイスを動作させる方法、及びこうしたデバイスを組立てる方法を提供する。【解決手段】薬物ポンプ用の挿入機構は、ハウジング202、スリーブ220、最初にエネルギー供給済み状態に保持される回転付勢部材210、引込み付勢部材216、及びニードル214の近位端に接続されるハブ212を含み、引込み付勢部材は、ハブとスリーブとの間で最初にエネルギー供給済み状態で保持される。ニードルは、回転付勢部材及びハブとハウジングとの間の相互作用によって目標組織に挿入される。ニードルの引込みは、引込み付勢部材を減圧するまたはエネルギー供給停止することによってもたらされる。薬物送達ポンプは、アクティブ化機構、駆動機構、減菌アクセス接続部、及び挿入機構を含む。【選択図】図8B
