Abstract

A dialysis system includes: a portable device configured to be carried by a patient and to read a marking displayed on a dialysis fluid container, the device obtaining data concerning at least one of a dialysis fluid type and a dialysis fluid volume from the marking; the device defined dialysate dwell time, alert patients for the next exchange and further configured to transfer the data to a computer; and wherein the computer is configured to use the data to track therapy progress of the product.

Claims

1. A dialysis system comprising:

a portable device configured to be carried by a patient, the portable device including;

a portable reader configured to (i) read a marking displayed on a dialysis fluid container to acquire data concerning at least one of a dialysis fluid type and a dialysis fluid volume from the marking and (ii) receive a patient weight signal from a weight scale;

a processor configured use the acquired data, including the at least one of the dialysis fluid type and the dialysis fluid volume, and the patient weight signal to determine a dialysis dwell time for at least one cycle of a dialysis therapy for a patient, the dialysis dwell time corresponding to a time to achieve at least one of (a) a specified ultrafiltrate level for the at least one cycle, (b) a urea removal level for the at least one cycle, and (c) a creatinine removal level for the at least one cycle; and

an output interface configured to provide an indication to the patient of a completion of the dialysis dwell time; and

a personal communication device communicatively coupled to the portable device and a computer, the personal communication device configured to transfer the acquired data to the computer to enable the computer to use the data to track therapy progress of the patient,

wherein the portable device communicates with the personal communication device on a first periodic basis and the personal communication device communicates with the computer on a second different periodic basis, and

wherein the portable device is configured to be worn as a necklace, configured to be worn on a key ring, or is integrated with the personal communication device such that the processor of the portable reader is a processor of the personal communication device.

2. The dialysis system of claim 1, wherein the portable device communicates with the personal communication device more frequently than the personal communication device communicates with the computer.

3. The dialysis system of claim 2, which is configured such that the portable device communicates with the personal communication device via a localized wireless communication technology and the personal communication device communicates with the computer via a satellite communication technology.

4. The dialysis system of claim 2, wherein the first periodic basis occurs after each reading is taken by the portable reader and the second periodic basis occurs daily.

5. The dialysis system of claim 1, wherein the computer is a computer of a doctor or clinician, the device configured to be brought to the computer.

6. The dialysis system of claim 1, wherein the personal communication device is configured to communicate with the computer via a localized wireless communication technology.

7. The dialysis system of claim 1, wherein the personal communication device is configured to receive a dialysis prescription from the computer and cause the output interface to display the dialysis prescription to the patient.

8. The dialysis system of claim 7, wherein the personal communication device is configured to automatically communicate with the computer.

9. The dialysis system of claim 1, wherein the portable reader includes a (i) barcode scanner, the marking displayed on the dialysis fluid container being a barcode or (ii) a radio frequency identification (“

RFID”

) reader, the marking displayed on the dialysis fluid container being an RFID tag.

10. The dialysis system of claim 1, wherein the portable reader is a first portable reader and the personal communication device includes a second portable reader and a base station, the second portable reader configured to read the marking and communicate with the base station, the base station configured to communicate with the second portable reader and the computer.

11. The dialysis system of claim 10, wherein the base station is configured to dock and charge the second portable reader.

12. The dialysis system of claim 10, which is configured such that the second portable reader communicates with the base station via a localized wireless communication technology and the base station is configured to communicate with the computer via an internet communication technology.

13. The dialysis system of claim 10, which is configured such that the second portable reader communicates with the base station on a first periodic basis and the base station communicates with the computer on a second periodic basis.

14. The dialysis system of claim 1, wherein at least one of the portable device and the personal communication device is further configured to receive a signal from a blood pressure cuff or a bioimpedance measurement device.

15. The dialysis system of claim 1, wherein the computer is a server computer that is configured to (i) communicate with a medical device professional and a supply warehouse and (ii) automatically order at least one solution bag for delivery to the patient.

16. A dialysis system comprising:

a portable device including a portable reader, a processor, and an output interface configured to be carried by a patient,

the portable reader configured to (i) read a marking displayed on a dialysis fluid container to acquire data concerning at least one of a dialysis fluid type and a dialysis fluid volume from the marking and (ii) receive a patient weight signal from a weight scale,

the processor configured use the acquired data, including the at least one of the dialysis fluid type and the dialysis fluid volume, and the patient weight signal to determine a dialysis dwell time for at least one cycle of a dialysis therapy for a patient, the dialysis dwell time corresponding to a time to achieve at least one of (a) a specified ultrafiltrate level for the at least one cycle, (b) a urea removal level for the at least one cycle, and (c) a creatinine removal level for the at least one cycle, and

the output interface configured to provide an indication of a completion of the dwell time;

a server computer in communication with the portable device, the portable device further configured to send supply usage data to the server computer;

a doctor/clinician computer in communication with the server computer, the doctor/clinician computer configured to send a therapy prescription for the patient to the server computer;

a supply warehouse computer in communication with the server computer; and

a delivery person communication device in communication with the server computer,

wherein the portable device, server computer, doctor/clinician computer and supply warehouse computer are linked such that the server computer can issue a supply order for the patient to the supply warehouse computer, the supply order taking into account the therapy prescription and the supply usage data, and wherein the delivery person communication device communicates the amount of supplies that are actually delivered to the patient.

17. The dialysis system of claim 16, wherein the doctor/clinician computer is configured to receive therapy compliance data for the patient from the server computer.
