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.

Claims

1. A dialysis system comprising:

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.

2. The dialysis system of claim 1, wherein the communication link is wired or wireless.

3. The dialysis system of claim 1, wherein the dialysis machine is configured to record an amount of UF that is removed from the patient over the first dialysis session and add that amount to the amount of UF removed over the second dialysis session to determine the total amount of UF removed.

4. The dialysis system of claim 1, wherein the first dialysis session is a nighttime treatment and the second dialysis session is a day exchange.

5. The dialysis system of claim 1, wherein the communication link includes an intermediate data transfer unit, which is configured to receive the recorded amount of UF removed from the remote exchange device.

6. The dialysis system of claim 5, wherein the intermediate data transfer unit and the remote exchange device communicate (i) wirelessly or (ii) over a wire.

7. The dialysis system of claim 5, wherein at least one of:

(i) the dialysis machine and the intermediate data transfer unit each include a memory storage member port, the memory storage member enabling the dialysis machine to receive the recorded amount of UF from the remote exchange device;

(ii) the dialysis machine and the intermediate data transfer unit are configured to communicate wirelessly so that the dialysis machine can receive the recorded amount of UF from the remote exchange device; and

(iii) the dialysis machine and the intermediate data transfer unit are configured to communicate via a wire so that the dialysis machine can receive the recorded amount of UF from the remote exchange device.

8. The dialysis system of claim 5, wherein the intermediate data transfer unit is further configured to receive, for communication to the dialysis machine, at least one of:

(i) blood pressure data, (ii) bioimpedance data, (iii) patient weight data, (iv) patient glucose level data, and (v) patient temperature data.

9. The dialysis system of claim 8, wherein at least one of:

(i) each of the different data is sent from a different apparatus corresponding to the particular data and (ii) each of the different data is sent to the intermediate data transfer unit wirelessly.

10. The dialysis system of claim 8, wherein the dialysis machine is a first dialysis machine, and which includes a second dialysis machine in communication with the intermediate data transfer unit for receiving the at least one data.

11. The dialysis system of claim 1, wherein the dialysis machine is further configured to receive at lease one of:

(i) blood pressure data, (ii) bioimpedance data, (iii) patient weight data, (iv) patient glucose level data, and (v) patient temperature data.

12. The dialysis system of claim 11, wherein at least one of:

(i) each of the different data is sent from a different apparatus corresponding to the particular data and (ii) each of the different data is sent to the dialysis machine wirelessly.

13. The dialysis system of claim 11, the dialysis machine a first dialysis machine, and which includes a second dialysis machine configured to receive the at least one data from a separate source than that for the first dialysis machine.

14. The dialysis system of claim 13, wherein at least one of the:

(i) dialysis machines and (ii) the separate sources are at least one of (a) encrypted and (b) provided with an authentication number for secure wireless communication.

15. A dialysis system comprising:

a dialysis machine;

a blood pressure sensor in wireless communication with the dialysis machine;

a patient weight sensor in wireless communication with the dialysis machine;

wherein the dialysis machine is a wireless slave to the wireless master blood pressure and weight sensors such that the dialysis machine is discoverable by the sensors when either the blood pressure or weight sensors is powered.

16. The dialysis system of claim 15, wherein the blood pressure and weight sensors are paired with the dialysis machine for secure wireless communication.

17. The dialysis system of claim 15, which includes at least one additional master sensor configured to send data wirelessly to the dialysis machine, the data of a type selected from the group consisting of:

patient temperature, patient hydration level, and patient glucose level.

18. A dialysis method comprising:

accumulating a first amount of ultrafiltration (“

UF”

) removed from a patient over a nighttime therapy automatically;

recording a second amount of UF removed from the patient over a day time exchange automatically;

sending the second amount of UF removed electronically to a location; and

at the location, summing the first and second UF amounts to arrive at a total UF amount removed from the patient for a twenty-four hour period.

19. The method of claim 18, the location being a dialysis machine, and which includes enabling a remote exchange device for making the recording to be moved within a proximity of the dialysis machine such that the second amount can be sent electronically to the dialysis machine.

20. The method of claim 18, wherein accumulating the first amount of UF removed includes accumulating UF over multiple fill, dwell and drain cycles.
