An apparatus for monitoring the intra-abdominal pressure of a hospitalized patient includes a urinary catheter connected to a urine valve providing selectable communication between a discharge end of the urinary catheter and either a drain or a fluid source. The hip joint comprises an acetabulum, being a part of the pelvic bone, and a caput femur, being the proximal part of the femoral bone. The apparatus also includes a bulb housing having a substantially annular shape that substantially corresponds to the shape of the light bulb to facilitate accommodation of the light bulb within the bulb housing. The system also includes an energy recovering assembly. With this arrangement, the deterioration of display quality caused by vertical cross-talk is reduced, minimized or resolved by correcting the image signal. The first shank portion has a length substantially equal to the water collecting opening in a gutter, while the second shank portion has a length substantially equal to one half the length of the first shank portion.
