1. A midstream urine collection device, the midstream urine collection device comprising:
a housing comprising an outer wall enclosing an interior volume, the interior volume having an upper portion which forms an initial collection well, and a lower portion which is divided by a dividing wall into an initial stream collection reservoir and a midstream collection reservoir;
a collection cavity formed on top of the housing by an upwardly-extending portion of the outer wall, the collection cavity having a collection drain in a bottom of the collection cavity to allow a urine stream to flow into the housing; and
a rotatable diverter having a deflection panel and an actuation panel joined along a fulcrum axis, the rotatable diverter being adapted to rotate between:
a first position in which the actuation panel is positioned to separate the initial collection well from the initial stream collection reservoir and the deflection panel is positioned to separate the initial collection well from the midstream collection reservoir, and
a second position in which the deflection panel deflects the urine stream received through the collection drain into the midstream collection reservoir,
wherein the actuation panel comprises a piece of permeable absorbent material affixed to a top surface of the actuation panel, within the initial collection well, when the rotatable diverter is in the first position;
wherein after fluid contact, the piece of permeable absorbent material is configured to maintain an increased weight while remaining affixed to the top surface of the actuation panel in the second position.
