Title:
埋込装置におけるバッテリ消耗検出システムと、バッテリ消耗検出方法
Document Type and Number:
Japanese Patent JP5000765
Kind Code:
B2
Abstract:
Abnormal battery depletion can be detected in an implantable medical device. Battery capacity consumed can be measured using a coulometer and using a capacity-by-voltage device, and the measurements can be blended to determine battery status. A drop in battery voltage below a specified threshold can be detected to identify a high-current depletion fault, and an alarm can be provided to indicate the fault has been detected. The specified threshold can be determined as a function of battery capacity consumed. Other aspects and embodiments are provided herein.
