Abstract:
1. An apparatus for measuring hydraulic pressure in the bladder of a medical patient comprising: a catheter adapted for draining urine from said patient into a drain conduit; a container of fluid; a first fluid path between said container of fluid and a discharge end of said catheter; a pump disposed to effect a pressure on fluid in said first fluid path; a pressure transducer arranged to measure a pressure of said fluid in said first fluid path at a location downstream of said pump; and a drain valve defining, at most, two fluid flow paths there-through, each such flow path extending from a valve housing entrance to a valve housing exit and being configurable to permit uninterrupted flow of fluid the entire length there-between, the drain valve being operable to occlude said drain conduit while permitting fluid flow through said first fluid path, said valve being configured to remain in association with said drain conduit when said valve is in a configuration to permit fluid flow through said drain conduit, the valve comprising structure configured to cause routing of a length of the first path, on the container-side of the valve and in the vicinity of the valve, to be disposed substantially in parallel with both of:
