Abstract: The Mobile, External, Prophylactic, Female, Urinary System is a uniquely-configured system which allows a human female to void their bladder without urinary frustration or bladder discomfort—whether lying, sitting, standing, walking or traveling. This system contains uniquely-sized and uniquely-shaped components which capture a discharged stream of urine from a human female urethra, and direct it smoothly into a capture-and-storage bag. The system is worn external to the body, which helps preclude urinary-tract infection. It can be worn under clothing. It is useful when the user has: urinary incontinence, or difficulty getting to a toilet, or difficulty finding a convenient place to urinate while traveling.
