A membrane catheter operating on the principle of pressure transmission across a latex membrane and permitting simultaneous recording of intravesical and urethral pressure is presented. A single and double membrane model are described in detail. Their use for accurate recording of urethral pressure profile and sphincteric activity, and responses to progressive bladder filling at the initiation and during the act of voiding are discussed. This catheter is also useful in neurophysiologic experimental studies as a means to record detrusor and sphinteric responses to various drugs, nerve stimulation, blocking. It is superior to water and gas perfusion catheters.
介绍了一种基于压力通过乳胶膜传递原理工作的膜式导管，该导管可同时记录膀胱内压和尿道压。详细描述了单膜和双膜模型。讨论了它们在准确记录尿道压力轮廓和括约肌活动，以及在排尿开始时和排尿过程中对膀胱逐渐充盈的反应方面的应用。这种导管在神经生理学实验研究中也很有用，可作为记录逼尿肌和括约肌对各种药物、神经刺激、阻断的反应的一种手段。它优于水灌注导管和气体灌注导管。
