- 経皮センサによって患者の分析を行うためのシステムであって、
当該患者に被着するためのベースユニット(1)と、前記ベースユニット(1)に着脱式に取り付けし得る、当該患者に前記センサを経皮挿入するための注入器(2)と、前記ベースユニット(1)に着脱式に取り付けし得る、前記センサによって測定データを生成させるための検出ユニット(3)とを有するシステムにおいて、
前記ベースユニット(1)は保持装置(4)を有し、前記保持装置は注入器(2)及び検出ユニット(3)と協働して次のように―つまり、前記ベースユニット(1)に検出ユニット(3)が配置された検出コンフィギュレーションにおいて、前記保持装置(4)によって、前記センサ(5)を当該摩擦係止固定するための圧接力が形成され、前記ベースユニット(1)に注入器(2)が配置された注入コンフィギュレーションにおいて、前記保持装置(4)によって、前記センサ(5)に対して、前記検出コンフィギュレーションに比較して僅少な圧接力が形成されるように―形成されていることを特徴とするシステム。 - 前記保持装置(4)は少なくとも一つのレバー部材(6)を有し、前記レバー部材は次のように―つまり、前記検出ユニット(3)の取り付けによって前記レバー部材(6)が前記センサの方向へ変位し得るように―配置及び形成されていることを特徴とする、請求項1に記載のシステム。
- 前記保持装置(4)は、前記レバー部材(6)と協働する弾性復元部材(6b)を有し、前記弾性復元部材は前記レバー部材(6)に対して前記センサ(5)から離反する方向への復元力を生ずるように形成されていることを特徴とする、請求項2に記載のシステム。
- 前記保持装置(4)は、前記センサ(5)を包囲するように配置された複数のレバー部材を有することを特徴とする、請求項2又は3に記載のシステム。
- 前記レバー部材は、環状に、好ましくは、均等に分散されて、前記センサ(5)を包囲して配置されていることを特徴とする、請求項4に記載のシステム。
- 前記検出ユニット(3)は、前記ベースユニット(1)に検出ユニット(3)が配置された際に、レバー部材(6)に対する、特に前記センサの方向への圧接力が形成されるように配置された圧接面を有することを特徴とする、請求項1から5のいずれか一項に記載のシステム。

- ベースユニット(1)と検出ユニット(3)、及び/又は、ベースユニット(1)と注入器(2)は、バヨネット継手による着脱式の取り付けのために形成されていることを特徴とする、請求項1から8のいずれか一項に記載のシステム。
- 前記センサ(5)は、注入位置において、前記保持装置(4)を貫通して配置し得ることを特徴とする、請求項1から9のいずれか一項に記載のシステム。
- 検出コンフィギュレーションにおいて、センサ(5)が注入位置に位置する際に、前記検出ユニット(3)は前記検出ユニット(3)の連結要素によって前記センサ(5)に密接するように形成されていることを特徴とする、請求項1から9のいずれか一項に記載のシステム。
- 前記連結要素は、光学的な連結要素として形成されていることを特徴とする、請求項11に記載のシステム。
