摘要为实现膀胱压力的实时测量,改善下尿路功能障碍患者的生活质量,设计一种可长期使用的植入式膀胱压力监测系统。该系统基于无线无源技术,由植入式膀胱压力检测器和体外控制器构成,两者之间通过无线方式传输数据。体外控制器具有设置压力阈值和排尿警报功能。植入式膀胱压力检测器采用无源式设计,能量直接由经皮电磁耦合从体外控制器供给,使其可不受电池容量限制而长期使用。通过软件处理,可增加系统稳定性,降低实现难度。经实验测试:该系统可测量的有效压力范围为266 ～1 284 cmH₂O(绝对压力),分辨率为0.1 cmH₂O。该系统可配合骶神经刺激器使用,实现反馈式闭环控制,更好地重建膀胱功能,为目前医学不能治愈的下尿路障碍患者提供一种新的治疗方案。
