Abstract

【課題】注射針の脱落を簡単な構成で信頼性良く検知する磁気検知装置を提供する。 【解決手段】検知対象用磁石と、磁気バイアス磁石と、磁気センサと、制御部と、リセット部と、記憶部と、警報部とを備え、制御部が、リセット部から送信される開始信号に応答して、磁気センサに、初期環境の磁界強度を測定させるとともに、定期的な時間間隔で磁界強度を測定させ、記憶部の初期磁界強度記憶手段に、初期環境の磁界強度を記憶させるとともに、計算手段に、初期環境の磁界強度と記憶部の閾値記憶手段に記憶された閾値とに基づいて警報を出すべき警報範囲を計算させ、かつ計算された警報範囲を比較手段に送信させ、比較手段に、定期的な時間間隔で測定された磁界強度と警報範囲とを比較させるとともに、測定された磁界強度が警報範囲を越える場合には、警報信号を警報部に送信させ、警報部に、警報信号に応答して注射針の脱落に対する警報を出させる。
