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. |
