Disclosed is an intercardiac defibrillation catheter system provided with a defibrillation catheter (100) and a power source device (700) wherein the defibrillation catheter (100) is provided with a memory (110) comprising an initial connection information storage unit (112) and an event information storage unit (113) and the power source device (700) is provided with an arithmetic processing unit (75) which comprises an output circuit (751) of direct current voltage, a memory (752) for storing a usage time limit, and an internal clock (753), and which controls writing to and reading from the memory (110) of the defibrillation catheter (100). The arithmetic processing unit (75), for each event that has been written to the event storage unit (113) of the memory (110) of the defibrillation catheter (100), performs control so that the next event is not executed if the elapsed time between the connection time that has been written to the initial connection information storage unit (112) of the memory (110) of the defibrillation catheter (100) and the time that the first-mentioned event has been performed has been determined to exceed the usage time limit.提供一種限於在性能或安全性上不會造成問題的時間內使用去顫導管的導管系統。具備有去顫導管(100)與電源裝置(700),去顫導管(100)係具備有記憶體(110),其具有:初次連接資訊記憶部(112)及事件資訊記憶部(113);電源裝置(700)係具備有運算處理部(75),其係具有:直流電壓的輸出電路(751)、記憶使用限制時間的記憶體(752)、及內部時鐘(753),控制對去顫導管(100)的記憶體(110)的寫入及讀出;運算處理部(75)係按每個被寫入在去顫導管(100)的記憶體(110)的事件資訊記憶部(113)的事件,若判斷出從被寫入在去顫導管(100)的記憶體(110)的初次連接資訊記憶部(112)的連接時刻起、至進行該事件的時刻為止的經過時間超過使用限制時間時,係以不會執行接下來的事件的方式來進行控制。71...DC電源部72...導管連接連接器73...心電儀連接連接器74...外部開關741...模式切換開關742...電氣能量設定開關743...充電開關744...電氣能量施加開關75...運算處理部753...內部時鐘751...輸出電路752...記憶體76...切換部77...心電圖輸入連接器78...心電位資訊顯示部100...去顫導管110...記憶體111...導管序列記憶部112...初次連接資訊記憶部113...事件資訊記憶部700...電源裝置800...心電儀900...心電位測定手段
