Abstract
Description
本発明の更に別の目的は、患者に対して、熱的エネルギー交換及び電極インターフェースを提供しながらも患者の快適さを高めることにある。
そのような目的にて、そして更に、患者に高効率な熱移動を提供するために、本発明のパッドは、患者と接触するために、流体循環層の第一の側部の少なくとも一部に、好ましくは大部分を覆って延びる接着面を含む。好ましくは、該接着面はまた、電極の少なくとも一部を覆うように、かつ該一部の周囲に延びており、患者と接触する実質的に連続した面を形成するとともに信頼できる電極のインターフェースを形成する。一例として、接着面は患者の皮膚に対して少なくとも約10g/in(3.94g/cm)の剥離値を備え得る。患者が使用する前に選択的な除去ができるように接着面上に剥離ライナーを設けることができる。
