Description
該凸部にはファンデルワールス力により皮膚に付着するようにした多数の超微細突起を備えさせたことを特徴とする接触針(請求項1)。
請求項1の発明による接触針は、基板に形成された多数の凸部にはファンデルワールス力により皮膚に付着するようにした多数の超微細突起を備えさせているため、該接触針は粘着剤を使用することなく皮膚に貼着する。したがって、粘着剤を使用したときに生ずる皮膚に対する好ましくない刺激、臭気等の問題は解消される。すなわち、本発明による接触針は、使用者に皮膚の不快な刺激、臭気等を感じさせることなく、疼痛緩和の効果を発揮する。
各凸部における先端径が10μm〜70μmであり、基板の片面から各凸部の頂部までの高さが50μm〜500μmである凸部を備え、かつ、各凸部に超微細突起を有しない上記従来の接触針の共振域は100Hz〜500Hz程度であった。これに対し、当該各凸部に超微細突起を備えさせ、該超微細突起は、先端径が1nm〜1000nm、高さが1nm〜5000nmであり、1nm〜1000nmのピッチで配設されている請求項2の発明による接触針においては、1Hz〜2500Hzまで共振域が拡大することが判明した。その結果、疼痛緩和の効果が更に高まる。
