Concentrate bottle used in blood dialysis machine - has stopper cooperating with fitting in dialysis machine to provide flow paths for dialysis fluid and thinned concentrate

摘要

The concentrate bottle holding a fluid or solid concentrate for the dialysis fluid used in the dialysis machine has an opening fitted with a stopper (220). This cooperates with a fitting (210) within the dialysis machine to provide a flow path to the interior of the concentrate bottle when the stopper and the fitting are coupled together, and a second flow path from the interior of the bottle to the dialysis machine. The inlet and outlet provided by the stopper are each coupled to a hose projecting into the interior of the bottle, with a filter at the free end of the hose for leading the thinned concentrate to the interior of the dialysis machine. ADVANTAGE - Reliable connection between dialysis machine and concentrate bottle.
