Development of an Urination Assist System - A Bladder Compressing System with a Link-Work Mechanism

In this paper, we propose a compact urination assist system that is implantable in a patient who has difficulty in urination caused by the decline of bladder muscular power, disconnection of the nerve to a bladder, etc. in order to assist the urination. The proposed system assists the urination by directly pushing the bladder of the patient using a link-work mechanism. SMA springs and Peltier elements are used to activate the proposed system. The effectiveness of the proposed system is evaluated by experiment.
