Description
本願は、2010年12月9日に出願され、「インピーダンス低減システムを備える電極」と題された米国仮出願シリアル番号第61/421,283号に基づき、米国特許法第119条(e)による優先権を主張し、その開示全体が引用により本明細書に援用される。
1.発明の分野
本発明は、医療用電極に関し、より詳細には、冗長インピーダンス低減システムを備え、除細動器のような着用式医療装置とともに使用可能な医療用電極に関する。
心停止および他の心臓病気は、世界中において、主な死亡原因である。患者の命を救うために、心停止中に罹病者の身体の循環系および呼吸器系を維持しようとする蘇生努力がさまざまある。これらの蘇生努力を早く開始すればするほど、罹病者が生存するチャンスは高くなる。これらの蘇生努力はコストが高く、かつ、成功率が低いため、特に、心停止は、罹病者の命を奪い続けている。
本発明の一局面によれば、電極アセンブリが与えられる。電極アセンブリは、電極アセンブリの電極部を形成する導電層と、第1インピーダンス低減システムと、第2インピーダンス低減システムとを含む。導電層は、人間の皮膚に隣接して配置される第1表面を有する。第1インピーダンス低減システムは、第1起動信号に応答して第1分量の第1導電性ゲルを導電層の第1表面上に供給するように構成される。第2インピーダンス低減システムは、第2起動信号に応答して第2分量の第2導電性ゲルを導電層の第1表面上に供給するように構成される。
本発明は、その用途において、以下の説明に記載され、または図面に図示された構成の詳細および要素の配置に限定されない。本発明は、他の実施形態も可能であり、さまざまな方法で実行または実施することができる。さらに、本明細書で用いられる語法表現および専門用語は、説明の目的のためであり、限定と見なされるべきではない。本明細書において、「含む」、「備える」、「有する」、「包含する」、「伴う」およびそれらの変形は、その後に列挙される項目およびそれらの均等物に加えて、追加の構成も含むことを意味する。
