Description

図４Ａおよび図４Ｂの実施形態は、電気的接点がカニューラに配置され、接点によって検知される皮膚または間質性液体の導電特性の変化が、カニューラの挿入状態を決定するのに用いられることを除いて、図１の実施形態と類似する。先の実施形態と同様、ハウジング１０８（糖監視オンボディセンサまたは注入セットまたはポンプの部分であり得る）は、カニューラ１４０が挿入される部位において、使用者の皮膚１０１に配置される基部１１４を含み、カニューレ１４０は、ハブ１０９に支持される。カニューラ１４０は、絶縁層１１５を備え、電気的に導電性の遠位電極１６４と近位電極１６２が、絶縁層１１５に配置される。図４Ａに見られるように、カニューラ１４０が対象の皮膚に完全に挿入されるとき、電極１６４および１６２は、共に、間質液の電解質の比較的な高濃度のために一般的に明確にされた導電性を有する、間室空間内にある。センサー回路１１６内の電流は、電極間を流れる。カニューラが、例えば、皮膚の表面が、図４Ｂにおけるように、テンティングによりゆがめられるときのように、完全に挿入されないなら、近位の電極１６２は、間室空間１０５に入らないであろうし、電極１６２、１６４間の導電性は、予測される方向に影響を受けるであろう。同様に、カニューラが、最初に正確に挿入され、その後に乱されたら、導電性の急速な変化が生じるであろう。
