Abstract

A peritoneal dialysis system includes an automated peritoneal dialysis (“APD”) machine including a logic implementer and a wireless interface receiver. The system also includes at least one of a scale or a blood pressure monitor including a wireless interface transmitter. The scale or blood pressure monitor is operable to send at least one of patient blood pressure data and patient weight data wirelessly, respectively, to the wireless interface receiver. The logic implementer is configured to store the patient blood pressure data or patient weight data. A server computer is configured to communicate with the logic implementer to receive the stored at least one patient blood pressure data and patient weight data.

Claims

1. A peritoneal dialysis system comprising:

an automated peritoneal dialysis (“

APD”

) machine including a wireless interface receiver and at least one of (i) an address and (ii) a personal identification number; and

a patient weight scale and a blood pressure monitor each including a wireless interface transmitter, the patient weight scale and the blood pressure monitor operable to send (i) at least one of (a) the address and (b) the personal identification number and (ii) patient weight data and patient blood pressure data wirelessly, respectively, to the wireless interface receiver.

2. The peritoneal dialysis system of claim 1, which includes a plurality of APD machines each including a wireless interface receiver, and

at least one of a scale and a blood pressure monitor associated with each of the plurality of APD machine wireless interface receivers, wherein each of the at least one scale and blood pressure monitor includes a wireless interface transmitter and is operable to send at least one of patient weight data and patient blood pressure data wirelessly, respectively, to the respective associated wireless interface receiver.

3. The peritoneal dialysis system of claim 1, wherein the patient weight scale and blood pressure monitor are operable to automatically send patient weight data and patient blood pressure data wirelessly, respectively, to the wireless interface receiver.

4. The peritoneal dialysis system of claim 1, wherein the APD machine includes at least one logic implementer, and wherein the patient blood pressure data and patient weight data sent wirelessly is stored on the APD machine logic implementer.

5. The peritoneal dialysis system of claim 1, which includes a server computer in communication with the APD machine, the server computer and APD machine programmed such that the APD machine can send patient ultrafiltration (“

UF”

) removed data to the server computer, the server computer configured to (a) remove anomalous data from the UF removed data and (b) output the UF removed data in a form suitable for a doctor/clinician to review the data and make a therapy adjustment if necessary.

6. The peritoneal dialysis system of claim 5, the form including a daily UF removed trend.

7. The peritoneal dialysis system of claim 6, which includes at least one of an upper and a lower UF limit, the at least one limit used with the daily UF removed trend to determine if therapy adjustment is necessary.

8. The peritoneal dialysis system of claim 7, the APD machine configured to send an alert to the server computer if an alert condition is met, the alert condition at least partially based upon a comparison of the daily UF removed trend to the at least one limit.

9. The peritoneal dialysis system of claim 7, the server computer configured to generate an alert if an alert condition is met, the alert condition at least partially based upon a comparison of the daily UF removed trend to the at least one limit.

10. The peritoneal dialysis system of claim 7, the at least one UF limit being a factor multiplied by an expected daily UF removal amount.

11. The peritoneal dialysis system of claim 5, the UF removed data including a moving average UF removed trend.

12. The peritoneal dialysis system of claim 11, which includes at least one of an upper and lower limit, the at least one limit used with the moving average UF removed trend.

13. A peritoneal dialysis system comprising:

an automated peritoneal dialysis (“

APD”

) machine including a wireless interface receiver and identifying information particular to the APD machine, the identifying information including at least one of (i) an address and (ii) a personal identification number, the wireless interface receiver operable to receive at least one of patient weight data and patient blood pressure data sent from the at least one scale and blood pressure monitor, respectively, when the wireless interface transmitter provides the identifying information to the APD machine.

16. The peritoneal dialysis system of claim 15, wherein the identifying information is sent wirelessly via a radio frequency transmission.

17. The peritoneal dialysis system of claim 15, wherein the wireless interface receiver is operable to automatically receive at least one of patient weight data and patient blood pressure data sent from the at least one scale and blood pressure monitor, respectively, when the wireless interface transmitter provides the identifying information to the APD machine.

18. A dialysis system comprising:

a dialysis machine;

a logic implementer operable with the dialysis machine, the logic implementer programmed to process blood pressure data, patient weight data and ultrafiltration data for a patient in connection with a treatment performed by the dialysis machine;
