There are several objections in the use of the conventional continuous drainage system with indwelling Foley catheter which are very commonly encountered in hospitals. For example, the bladder is always kept contracted with small amounts of residual urine which might results in the spread of infection to the bladder. The present study relates to basic design of a bladder assist device, "BLADMAN^[○!R]", composed of concentric type syphon which is simple in construction and comparatively inexpensive to manufacture. The object is to provide an intermittent drainage system which simulates the normal periodic filling and emptying of the bladder with indwelling catheter.Another object is to provide a tidal irrigating unit for the automatic irrigation of the bladder without the need of an attendant's continuous attention. In order to design the form, dimension, construction and arrangement of several elements of the syphon for the bladder assist device, urodynamic studies were performed in in vitro model system which simulated the clinical situation. It was found that there should be provided a filter at the top of the housing of the syphon so as to empty the bladder completely by syphonic action.
