Abstract:
1. A urine collection apparatus for collecting urine expelled from a person fitted with a urinary catheter, the urine collection apparatus comprising: a bag formed of plastic film defining an interior volume in fluid communication with the urinary catheter, said bag being capable of expanding from an empty collapsed condition to an enlarged non-collapsed condition upon receipt of urine from the urinary catheter, wherein in the enlarged non-collapsed condition the interior volume of the bag is occupied at least in part by urine; and a check valve located in an upper portion of said bag, said check valve comprising wherein said check valve is configured to be in a closed position with the valve disc engaged with the valve seat to seal said interior volume from a surrounding atmosphere when pressure within said bag is approximately equal to pressure of the surrounding atmosphere, wherein said check valve is configured to open to an open position with the valve disc flexed and disengaged from the valve seat to admit gas from the surrounding atmosphere into the bag when the pressure within said bag is less than the pressure of the surrounding atmosphere, wherein said check valve functions to substantially equilibrate the pressure within the bag with the pressure of said surrounding atmosphere as urine is received from the urinary catheter, wherein the check valve has an interior side that faces the interior volume of the bag and an exterior side that faces the surrounding atmosphere, and wherein the check valve continues to function notwithstanding that the interior side of the check valve has been contacted by urine.
