Abstract: A pressure controlled valve apparatus for use with a catheterized bladder or the like to selectively control fluid flow therefrom comprising a fluid reservoir including a primary fluid reservoir chamber and a secondary fluid reservoir chamber in open fluid communication relative to each other to receive fluid from the catheterized bladder and a fluid flow control including a primary control valve and a secondary control valve each selectively movable between a first and second position, the primary control valve disposed to seal the primary fluid reservoir chamber when in the first position and to unseal the primary fluid reservoir chamber when in the second position in response to a first predetermined pressure to release fluid from the catheterized bladder and the primary fluid reservoir chamber to a fluid collection container and the secondary control valve disposed to seal the secondary fluid reservoir chamber when in the first position and to unseal the secondary fluid reservoir chamber when in the secon
