Abstract:
A dialysis machine includes: (i) a source of peritoneal dialysis solution; (ii) a patient line for passing the peritoneal dialysis solution to the peritoneal cavity of a patient; (iii) a pump for pumping the peritoneal dialysis solution to the peritoneal cavity via the patient line; (iv) a heater for heating the peritoneal dialysis solution prior to the dialysis solution reaching the patient line, the heater including first and second heating elements; (v) a voltage input from a remote power source; and (vi) a control scheme responsive to the voltage input and configured to (a) automatically maintain a proper dialysis solution temperature for the patient via the first and second heating elements regardless of the voltage input wherein the control (b) account for an inlet temperature of the dialysis solution to the heater and (c) account for heater efficiency.
Abstract:
A dialysis machine includes: a source of dialysis solution; a pump configured to pump the dialysis solution; a heater configured to heat the dialysis solution; an electrical input receiving power from a remote power source; and a housing supporting the pump, the heater and the electrical input, the housing including an electrical insulation rated for 240 VAC such that the remote power source can be either 110 or 240 VAC.

Abstract:
A dialysis system includes: a dialysis machine for performing a first dialysis session on a patient at a first time of a day; a remote exchange device for performing a second dialysis session on the patient at a second time of the day, the remote exchange device configured to record an amount of ultrafiltration (“UF”) that is removed from the patient over the second dialysis session; and a communication link between the dialysis machine and the remote exchange device, wherein the dialysis machine is configured to receive the recorded amount UF removed from the remote exchange device via the communication link and determine a total amount of UF removed from the patient over the first and second sessions.

Abstract:
A method, system and apparatus for performing peritoneal dialysis are provided. To this end, in part, a method of controlling a medical fluid heater is provided. The method includes the steps of determining a first heater control output based on a number of measured inputs for the heater and at least one mathematical relationship between at least two of the measured inputs, determining a second heater control output based on at least one fuzzy logic membership function and at least one fuzzy logic rule, and determining a third heater control output based on the first and second outputs and using the third heater control output to control the heater.
