Abstract

An example renal therapy system includes a blood pressure monitor configured to output blood pressure data concerning a patient and a renal therapy machine communicatively coupled to the blood pressure monitor. The renal therapy machine is configured to generate ultrafiltration (“UF”) removed data from a prescribed renal therapy treatment performed by the renal therapy machine on the patient, and transmit the UF removed data and the blood pressure data via a network. At least one of a UF trend or a blood pressure trend from the UF removed data or the blood pressure data is determined, enabling a further determination as to at least one of (a) whether a prescribed renal therapy treatment adjustment or a new prescribed renal therapy treatment needs to be made, (b) whether the patient is complying with the prescribed renal therapy treatment, or (c) whether a condition related to an alarm or an alert exists.

Claims

1. A renal therapy system comprising:

a renal therapy machine configured to

perform a dialysis treatment on a patient according to a prescription,

generate ultrafiltration (“

UF”

) removed data over the dialysis treatment performed by the renal therapy machine, and

transmit the UF removed data;

a receiver coded with at least one of an address or a personal identification number (“

PIN”

), the receiver configured to

receive blood pressure data from a blood pressure monitor over a frequency, data rate, or communication protocol, the blood pressure monitor located external to the renal therapy machine,

receive the UF removed data from the renal therapy machine, and

transmit the blood pressure data and the UF removed data via a network; and

a server communicatively coupled to the receiver via the network, the server configured to

determine at least one of a UF trend or a blood pressure trend from at least one of the UF removed data or the blood pressure data, and

display information indicative of the at least one of the UF trend or the blood pressure trend,

wherein the at least one coded address or PIN is provided with the blood pressure data that is sent to the receiver, and

wherein the receiver is configured to compare the at least one coded address or PIN to the coded address or PIN provided with the blood pressure data to ensure that the blood pressure data is received and processed by the receiver as opposed to extraneous data received over the same frequency, data rate, or communication protocol from sources other than the blood pressure monitor, including devices in proximity of the renal therapy machine.

2. The renal therapy system of claim 1, wherein the prescription is a first prescription, and the server is further configured to:

access the at least one of the UF trend or the blood pressure trend to process at least one of (a) a generation of a plurality of regimens and filtration of one or more new second prescription from the regimens, or (b) a generation of a set of filter criteria for filtering a set of new second prescriptions; and

transmit a message via the network related to at least one of (a) or (b).

3. The renal therapy system of claim 2, wherein the receiver includes a display device and is further configured to:

receive the message via the network related to the at least one of (a) or (b); and

display the message, the message prompting input or action from a user concerning at least one of (a) or (b).

4. The renal therapy system of claim 3, wherein the receiver is configured to receive at least one of the UF trend or the blood pressure trend from the server and the display device is configured to display the at least one of the UF trend or the blood pressure trend.

5. The renal therapy system of claim 1, wherein the receiver is separate from the renal therapy machine.

6. The renal therapy system of claim 5, wherein the receiver includes a display device and is configured to display the UF removed data and the blood pressure data.

7. The renal therapy system of claim 6, wherein the display device is a display device of a cell phone or a computer.

8. The renal therapy system of claim 1, wherein the receiver is included in the renal therapy machine.

9. The renal therapy system of claim 1, wherein the renal therapy machine is configured to perform at least one of an automated peritoneal dialysis (“

APD”

) therapy treatment, a continuous cycling peritoneal dialysis (“

CCPD”

) therapy treatment, or a hi-dose CCPD therapy treatment.

10. The renal therapy system of claim 1, wherein the receiver is configured for at least one of Bluetooth®

, WiFi™

, or Zigbee™

.

a receiver coded with at least one of an address or a personal identification number (“

PIN”

), communicatively coupled to the blood pressure monitor, and configured to receive the blood pressure data outputted by the blood pressure monitor over a frequency, data rate, or communication protocol; and

a renal therapy machine communicatively coupled to the receiver and configured to

generate ultrafiltration (“
