An apparatus for withdrawing a urethral catheter at a constant speed is described. The motor and the puller assembly are separate components so that the puller assembly can be autoclaved. By matching pulling speed to recorder chart speed a reproducible representation of urethral length can be obtained without using a displacement transducer. The apparatus has been used clinically for measuring urethral pressure profiles.
描述了一种用于以恒定速度拔出尿道导管的装置。电机和牵拉器组件是分开的部件，以便牵拉器组件能够进行高压灭菌。通过使牵拉速度与记录图表速度相匹配，无需使用位移传感器就能获得尿道长度的可重复表示。该装置已在临床上用于测量尿道压力分布。
