Claims (3)
- 被検体の内部に配置され、前記被検体の内部の情報を取得する情報取得部を具備したカプセル型医療装置において、
前記カプセル型医療装置の表面に配置され、前記情報取得部が取得した前記情報を前記被検体の外部に対して出力する複数の通信用電極と、
前記情報取得部における前記情報の取得状態に応じて入力される情報信号に基づき、前記通信用電極間に電位差を生じさせて駆動させるための電極駆動信号を出力する信号出力部と、
前記信号出力部から前記通信用電極へ前記電極駆動信号を出力可能な接続状態と、前記信号出力部から前記通信用電極への前記電極駆動信号が出力されない非接続状態とを切り替える信号出力切替部と、
前記非接続状態において、前記情報取得部から前記信号出力部への前記情報信号の出力状態を監視することにより、前記電極駆動信号の出力状態が所定の期間以上変動していない場合においてタイムアップ信号を生成して出力するタイマ部に対し、前記情報取得部から前記信号出力部への前記情報信号の出力が再開されたことを検出すると、前記タイムアップ信号の出力を停止させるための制御を行う制御部と、
前記タイマ部からの前記タイムアップ信号が入力された際に、前記信号出力切替部を前記接続状態から前記非接続状態へ切り替える制御を行うとともに、前記タイマ部からの前記タイムアップ信号が入力されている期間において、前記信号出力切替部を前記非接続状態のまま維持する制御を行う信号切替制御部と、
を有することを特徴とするカプセル型医療装置。 - 前記非接続状態において、前記通信用電極各々の電位が所定の電位に設定されることを特徴とする請求項1に記載のカプセル型医療装置。
- 前記所定の電位は、接地電位であることを特徴とする請求項2に記載のカプセル型医療装置。
