An urethral drain having deep external drainage channels, a low-profiled bladder retention segment, and a reversibly detachable collection segment, facilitates the draining of urine and fluids from the bladder. The low-profiled retention means minimizes bladder irritations and the deep external channels reduce the occurrence of infections. Incorporation of a reduced diameter smooth segment on the catheter, proximate the location of the external urethral sphincter allows the patient to void normally and at will. Modifying the size of this smooth segment aids the function of a defective sphincter in controlling urine leakage. The drain can be worn concealed within the urethra. Flushing action from normal voiding washes out particulate matters in the urethra and the concealed drain further minimizes contamination. Together, these features improve quality of life for patients needing catheterization.

Techniques for detecting stress urinary incontinence use a pressure sensing catheter the electrical indications of which are applied to a processing unit for detecting pressure levels generated during involuntary coughs.

An apparatus and method for collecting urine from an incontinent person including a condom catheter fluidly coupled to the inlet of a urine pump, with the outlet of the pump fluidly coupled to a urine collection bag suspended about the person's abdomen by an integral strap. The pump is fastened to the strap adjacent to the urine bag. The pump mechanism has a resilient flexible tubular section that is provided with inlet and outlet check valves and functions by displacing liquid present within the tubular section by physically deforming the tubing. A cam, driven by a solenoid, causes a crimping of the tubular section which expels fluid through pump discharge. When the force causing physical deformation is released, the resilient tubular section returns to its original shape, providing a suction at the pump inlet. For continuous or intermittent pumping, the solenoid is repeatedly actuated and de-energized according to a timing sequence that is user controllable according to expected urine leakage conditions via the electronic control circuitry. When the user wishes to urinate, the user may simply void in the normal fashion, as free flow of urine through pump assembly is permitted. A manual activation switch allows the user to pump accumulating fluid from the condom catheter independently of the timing sequence, if needed.

A penile compression device for preventing urinary leaking and method for the same. First and second semi-rigid support arm are connected at opposing ends in their length direction.
