Abstract
【解決手段】物質(例えば流体)をリザーバ(34)から移すピストン(30)を有する供給装置用の光センサ。光センサは光源(42)と、ピストンに連結されたプランジャロッド(38)に沿って配置された符号化特徴をイメージングするための検出器アレー(44)と、を有する。符号化特徴のパターンによって、基準の位置と関連するプランジャロッドの絶対位置が、独自に決定され得る。このように、リザーバに残っている流体量、流体供給の速度およびリザーバの適切な負荷が正確に確認され得る。加えて、符号化は、例えば、分配される治療薬の異なる濃度に対応するさまざまなバージョンにおいて供給され得るリザーバのバージョンを独自に識別するのに役立つことができる。

治療薬を患者の体内に供給するためのポンプの主要素は、図1に関して記載されている。
薬剤リザーバ11(典型的には円筒形状)は、ハウジング16内に保持され、供給管18および皮下注射針(図示せず)を介して患者に供給される液状薬剤を含む。そのリザーバに含まれる液状薬剤は、リザーバの軸と同軸方向8に沿って、ピストン30の線形運動によって、決定された速さでリザーバから押し出される。減速ギアドライブを介してスクリュードライブ14に連結されたモーター(見えない)によって、ピストンは、順番に、所定の速度で駆動されるプランジャロッド12によって動かされる。本発明は、ポンプ(例えばインスリンペン)以外の供給装置のために都合よく適用され得ると理解され、同様に、様々な流体の供給、または薬剤または他の物質であり得る物質の供給装置のために都合よく適用され得ると理解される。ポンプの、そして患者への治療薬の供給に関する説明は限定することなく、そして、実施形態だけとしてある。本発明の実施形態は、例えば、給水に浄化剤の供給のためにも、都合よく適用され得る。供給される流体は典型的には液体であるが、本願明細書において記載され、そして添付の特許請求の範囲でクレームしているように、他の物質の供給もまた本発明の範囲内である。
a. 供給精度をモニターすること;
b. リザーバ(例えばその内容に関して)の特徴を識別すること;
c. リザーバに残っている流体量を決定すること;および
d. リザーバの適切な負荷を検査すること。
例えば制限ストッパ)に動かされ得る。
本発明の好ましい実施形態において、ほぼ16μmのピクセル解像度については、検出器44は、512ピクセルの線形配列として理解される。検出器44は、プランジャロッド38の移動線に沿ってかつ平行に配置され、リードねじ40の端部で実質的に開始する。特に、集束光学素子が使用されないとき、検出器44がプランジャロッド38に非常に近くに配置されるのが好ましい。
、その結果、一つより多くないスロットがイメージセンサの視野の中にある場合、リザーバのバージョンは独自に識別され得る。
画像を作成するために、検出器44の全てのピクセルがリセットされる。それから、光が指定された時間発光するように光源42が発光する。可変の露出時間が採用され得、スロットが見られるときは、より長い時間が使われる、しかし、プランジャロッドの端部が見られるときには、より短い時間が使われる。スロットにおいては5mの露出時間が、ロッドの端部においては0.7mの露出時間が満足であるとわかった。配列のプロセッサ56によって保存され、一つ以上のアルゴリズムを使用して解釈される、各々のピクセルの値とともに、検出器44からの信号が読み込まれる。
