Abstract

A system and method are disclosed for the automated collection of dialysis data. An example method includes receiving and aggregating dialysis data comprising a fill volume amount and a drain volume amount for at least one continuous ambulatory peritoneal dialysis (“CAPD”) cycle. The method also includes calculating an amount of ultrafiltration removed for each CAPD cycle by subtracting the fill volume amount from the drain volume amount for the respective CAPD cycle, and storing ultrafiltration data that is indicative of the amount of ultrafiltration removed as part of the aggregated dialysis data. The method further includes determining or receiving an indication that a dialysis machine is connected. After the dialysis machine is connected, the method includes transmitting the aggregated dialysis data to the dialysis machine to enable the aggregated dialysis data to be combined with additional dialysis data generated by the dialysis machine for determining total dialysis data.

First claim

The invention is claimed as follows:

1. A system for recording continuous ambulatory peritoneal dialysis (“CAPD”) data, the system comprising:
a dialysis machine; and
a data transfer unit including:
an input device for receiving dialysis data from a patient, the dialysis data including a fill volume amount and a drain volume amount for at least one CAPD cycle;
a transceiver for communicative coupling to the dialysis machine; and
a processor communicatively coupled to the input device and the transceiver, wherein the processor in conjunction with the input device and the transceiver are configured to:
aggregate the received dialysis data over a defined time period, and
after the transceiver is communicatively coupled to the dialysis machine, transmit the aggregated dialysis data to the dialysis machine to enable the aggregated dialysis data to be combined with additional dialysis data generated by the dialysis machine for determining total dialysis data for the defined time period,
wherein the processor is configured to automatically transmit the aggregated dialysis data after detecting the communicative coupling to the dialysis machine.

2. The system of claim 1 , wherein the defined time period includes a twenty-four hour time period.

3. The system of claim 1 , wherein the dialysis machine includes an automated peritoneal dialysis machine.

4. The system of claim 1 , wherein the processor is configured to:
calculate an amount of ultrafiltration removed for each CAPD cycle by subtracting the fill volume amount from the drain volume amount for the respective CAPD cycle; and
transmit ultrafiltration data that is indicative of the amount of ultrafiltration removed to the dialysis machine as part of the aggregated dialysis data.

5. The system of claim 4 , wherein the dialysis machine uses the ultrafiltration data to calculate a total amount of ultrafiltration removed by the dialysis machine and during the at the at least one CAPD cycle.

6. The system of claim 1 , further comprising a video monitor, wherein the processor is configured to cause the video monitor to display the aggregated dialysis data.

7. The system of claim 1 , wherein the processor is configured to transmit the aggregated dialysis data after the input device receives an entry from a user.

8. The system of claim 1 , wherein the transceiver includes at least one of a wireless transceiver or a wired transceiver.

9. The system of claim 1 , wherein the processor in conjunction with the input device and the transceiver are configured to:
receive 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; and
transmit the at least one of (i) to (v) to the dialysis machine as part of the aggregated dialysis data.

10. A method for recording continuous ambulatory peritoneal dialysis (“CAPD”) data, the method including:
receiving, in an input device, dialysis data, the dialysis data including a fill volume amount and a drain volume amount for at least one CAPD cycle;
aggregating, via a processor connected to the input device, the dialysis data over a defined time period;
calculating, via the processor, an amount of ultrafiltration removed for each CAPD cycle by subtracting the fill volume amount from the drain volume amount for the respective CAPD cycle;
storing, via the processor, the aggregated dialysis data and ultrafiltration data that is indicative of the amount of ultrafiltration removed;
determining or receiving an indication, via a transceiver and the processor, that a dialysis machine is connected to the processor for receiving the aggregated dialysis data; and
after the dialysis machine is connected to the processor, transmitting, via the transceiver and the processor, the aggregated dialysis data including the ultrafiltration data to the dialysis machine to enable the aggregated dialysis data and the ultrafiltration data to be combined with additional dialysis data generated by the dialysis machine for determining total dialysis data for the defined time period.

11. The method of claim 10 , further comprising calculating, via the dialysis machine, a total amount of ultrafiltration removed by the dialysis machine and the at least one CAPD cycle using the ultrafiltration data.

12. The method of claim 10 , wherein the dialysis data is entered into the input device by at least one of a patient or a clinician.

13. The method of claim 10 , wherein the at least one CAPD cycle is a day exchange and the additional dialysis data is generated during a nighttime treatment.

14. The method of claim 10 , wherein the defined time period includes a twenty-four hour time period and the dialysis machine includes an automated peritoneal dialysis machine.

15. The method of claim 10 , wherein the aggregated dialysis data is transmitted automatically after the connection with the dialysis machine is detected.

16. The method of claim 10 , wherein the aggregated dialysis data is transmitted after the input device receives an entry from a user.

17. The method of claim 10 , further comprising:
receiving, via the processor, 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; and
transmitting, via the processor and the transceiver, the at least one of (i) to (v) to the dialysis machine as part of the aggregated dialysis data.

18. The method of claim 10 , further comprising displaying, via the processor and a video monitor, the aggregated dialysis data.

19. The method of claim 10 , wherein the input device, the processor, and the transceiver are included within a remote dialysis fluid exchange device.
