The present invention provides a generally hollow vessel which articulates with the female genitalia and, when left in situ, functions to opportunistically collect urine when the patient inevitably voids her bladder. The device is further designed to sequester the first portion of said urine, which tends to be unsuitable for diagnostic testing, and then, divert the remainder of relatively uncontaminated urine, preferably into a collection receptacle where it can be easily accessed for testing.
