Abstract

A dialysis system includes: a dialysis machine; and at least one of a blood pressure sensor and a weight sensor in wireless communication with the dialysis machine, wherein the dialysis machine is so positioned and arranged relative to the at least one blood pressure sensor or weight sensor that the dialysis machine is discoverable by the at least one blood pressure sensor or weight sensor when the at least one blood pressure sensor or weight sensor, respectively, is powered, and such that the at least one blood pressure sensor or weight sensor becomes paired automatically with the dialysis machine for secure wireless communication.

Claims

1. A dialysis system comprising:

a dialysis machine; and

at least one of a blood pressure sensor and a weight sensor in wireless communication with the dialysis machine,

wherein the dialysis machine is so positioned and arranged relative to the at least one blood pressure sensor or weight sensor that the dialysis machine is discoverable by the at least one blood pressure sensor or weight sensor when the at least one blood pressure sensor or weight sensor, respectively, is powered, and such that the at least one blood pressure sensor or weight sensor becomes paired automatically with the dialysis machine for secure wireless communication.

2. The dialysis system of claim 1, which includes at least one additional sensor configured to discover and send data wirelessly to the dialysis machine, the data of a type selected from one of (i) patient temperature, (ii) patient hydration level and (iii) patient glucose level.

3. The dialysis system of claim 1, wherein the dialysis system is a peritoneal dialysis system.

4. The dialysis system of claim 1, wherein the dialysis machine is a first dialysis machine, and which includes a second dialysis machine discoverable by the at least one blood pressure sensor and weight sensor.

5. The dialysis system of claim 1, wherein the dialysis machine is wirelessly paired with the at least one blood pressure sensor or weight sensor by entering an identifier for the blood pressure sensor or weight sensor into the dialysis machine.

6. The dialysis machine of claim 5, wherein the identifier is entered into the dialysis machine upon the dialysis machine receiving a request from the corresponding sensor.

7. The dialysis machine of claim 5, which is configured such that a measurement is taken by the corresponding sensor prior to the identifier being entered into the dialysis machine.

8. The dialysis system of claim 1, wherein the dialysis machine is configured and arranged to be set in a discoverable mode after being powered for discovery by the at least one blood pressure or weight sensor.

9. A dialysis system comprising:

first and second dialysis machines;

a blood pressure sensor including a blood pressure sensor identifier configured to wirelessly communicate with the first or second dialysis machine when the blood pressure sensor identifier is entered into the first or second dialysis machine, respectively, the blood pressure sensor further configured to wirelessly communicate with only one dialysis machine at a time; and

a weight sensor including a weight sensor identifier configured to wirelessly communicate with the first or second dialysis machine when the weight sensor identifier is entered into the first or second dialysis machine, respectively, the weight sensor further configured to wirelessly communicate with only one dialysis machine at a time,

wherein the first or second dialysis machine is paired with the blood pressure sensor or the weight sensor after the respective identifier is entered into the first or second dialysis machine.

10. The dialysis system of claim 9, which is configured such that a reading be taken by the blood pressure sensor prior to the blood pressure sensor identifier being entered into the first or second dialysis machine.

11. The dialysis system of claim 9, which is configured such that a reading be taken by the weight sensor prior to the weight sensor identifier being entered into the first or second dialysis machine.

12. The dialysis system of claim 9, which includes at least one additional sensor configured to discover and send data wirelessly to the first or second dialysis machine, the data of a type selected from one of (i) patient temperature, (ii) patient hydration level and (iii) patient glucose level.

13. A dialysis system comprising:

first and second dialysis machines; and

at least one of a blood pressure sensor and a weight sensor, each sensor configured to prompt one of the first and second dialysis machines to enter an identifier for the sensor,

wherein the first or second dialysis machine is paired with the at least one of the blood pressure sensor or weight sensor after the respective identifier is entered into the first or second dialysis machine.

14. The dialysis system of claim 13, wherein the first or second dialysis machine that is prompted is the dialysis machine that is set into a discoverable mode after being powered.

15. The dialysis system of claim 13, which is configured such that a measurement is taken by the at least one blood pressure or weight sensor prior to its respective identifier being entered into the first or second dialysis machine.

16. A dialysis system comprising:

a first dialysis machine having a first user name and a first password;

a second dialysis machine having a second user name and a second password; and

an intermediate data transfer unit configured to communicate data to the first or second dialysis machine when the respective user names and passwords are entered into the intermediate data transfer unit.

17. The dialysis system of claim 16, wherein the intermediate data transfer unit is configured to receive wireless data from at least one of (i) a blood pressure sensor (ii) a weight sensor, (iii) a temperature sensor, (iv) a bioimpedance sensor and (v) a glucose monitor.

18. The dialysis system of claim 16, the data being first data for a first patient, wherein the intermediate data transfer unit is configured to erase the first data so as to enable the intermediate data transfer unit to receive second data for a second patient.

19. The dialysis system of claim 16, wherein the intermediate data transfer unit is configured to communicate data for a first patient to the first dialysis machine, be erased, and communicate data for a second patient to the second dialysis machine.

20. The dialysis system of claim 16, wherein the intermediate data transfer unit and the dialysis machines communicate (i) wirelessly or (ii) over a wire.
