  • Publication number: 20100094173
    Abstract: Described is, e.g., an apparatus (100), and associated methods of manufacture and use, for draining a fluid, discharged from a urinary catheter (104) installed in a subject's bladder, into a drain container (138) while avoiding undesired pressure states in such bladder. A drain conduit (102) connected to the catheter has a sufficiently small size as to maintain plug-flow between opposite ends of the drain conduit. The discharge end of the drain conduit is connected to a siphon-break apparatus (106) configured to cause a siphon-break disposed at an elevation (132) in approximate agreement with the subject's bladder. The potential energy from fluid downstream of the siphon-break location is decoupled from fluid in the drain conduit.
