Foldable dialysis unit with integral pump and a method for performing solution exchange
First Claim
1. A system for controlling fluid flow, the system comprising:
- a holder capable of holding a first container having a first solution therein;
a processor unit having an integral pump connected to the holder wherein the pump is capable of pumping the first solution from the first container in the holder;
a tray capable of holding a second container wherein the pump is capable of pumping a second solution to the second container; and
an arm connecting the holder to the processor unit wherein the arm includes a hinge at a point of connection to the processor unit such that the arm is rotatable with respect to the processor unit.

Abstract
A system and a method are provided to effect solution exchange particularly for a patient requiring peritoneal dialysis. The system includes a device (1) that is portable and particularly adaptable for patients requiring a night time exchange or an additional exchange. The device (1) includes an operator-touch control panel (10) operatively connected to a pouch (26) with an incorporated heater (12). The pouch (26) holds a solution bag (18) and may be selectively opened and closed by a cover (28). A drain tray (30) holds a drain bag (20) and has a scale (14) incorporated therein. The pouch (26) is connected to the control panel (10) by an upper arm (38), and the drain tray (30) is connected to the control panel (10) by a lower arm (42). The device (1) may be collapsed by releasing the upper arm (38) and the lower arm (42) such that the system (1) lays in a substantially flat arrangement when not in use.
