Abstract

In certain aspects, a method includes determining that one or more alarm criteria of a first alarm condition of a dialysis machine is satisfied, and in response to determining that the one or more alarm criteria of the first alarm condition is satisfied, activating an alarm corresponding to the first alarm condition and activating a peripheral device.

Claims

1. A method comprising:

determining that one or more alarm criteria of a first alarm condition of a dialysis machine is satisfied; and

in response to determining that the one or more alarm criteria of the first alarm condition is satisfied, activating an alarm corresponding to the first alarm condition and activating a peripheral device.

2. The method of claim 1, wherein the peripheral device is activated by transmitting to the peripheral device peripheral activation data associated with the first alarm condition.

3. The method of claim 2, wherein the peripheral activation data associated with the first alarm condition is wirelessly transmitted to the peripheral device.

4. The method of claim 1, wherein determining that the one or more alarm criteria of the first alarm condition is satisfied comprises monitoring data associated with the dialysis machine and comparing the data to the one or more alarm criteria of the first alarm condition.

5. The method of claim 4, wherein the data associated with the dialysis machine comprises pressure data.

6. The method of claim 1, wherein determining that the one or more alarm criteria of the first alarm condition is satisfied comprises accessing a look-up table that comprises the first alarm condition and the one or more alarm criteria and peripheral activation data associated with the first alarm condition.

8. The method of claim 1, wherein the method comprises activating a plurality of peripheral devices in response to determining that the one or more alarm criteria of the first alarm condition is satisfied, at least one of the peripheral devices waking a patient upon being activated and at least one of the peripheral devices drawing the patient'"'"'s attention to a particular part of the system upon being activated.

10. The method of claim 1, wherein activating the peripheral device causes the peripheral device to transmit data to a remote location.

12. The method of claim 1, further comprising, in response to determining that one or more alarm criteria of a second alarm condition is satisfied, activating an alarm corresponding to the second alarm condition and activating a peripheral device.

13. The method of claim 12, wherein the peripheral device activated in response to determining that the one or more alarm criteria of the second alarm condition is satisfied differs from the peripheral device activated in response to determining that the one or more alarm criteria of the first alarm condition is satisfied.

14. The method of claim 12, wherein activating the peripheral device in response to determining that the one or more alarm criteria of the first alarm condition is satisfied causes a first part of the dialysis machine to be illuminated, and activating the peripheral device in response to determining that the one or more alarm criteria of the second alarm condition is satisfied causes a second part of the dialysis machine to be illuminated.

15. The method of claim 12, wherein, in response to determining that the one or more alarm criteria of the first alarm condition is satisfied, a plurality of first peripheral devices are activated, at least one of the first peripheral devices waking a patient upon being activated and at least one of the first peripheral devices drawing the patient'"'"'s attention to a particular part of the system upon being activated.

19. The method of claim 1, wherein the first alarm condition is indicative of a condition of a disposable component of the dialysis system.

20. The method of claim 19, wherein the first alarm condition is indicative of a malfunction of the disposable component.

22. The method of claim 19, wherein activating the peripheral device causes the peripheral device to provide feedback drawing a patient'"'"'s attention to the disposable component.

24. A computer readable storage device storing instructions that, when executed, cause a computer system to perform operations comprising:

accessing a look-up table of a plurality of alarm conditions associated with a dialysis machine, each of the alarm conditions being associated with one or more alarm criteria and one or more peripheral activation data;

monitoring one or more states of the dialysis machine, each state being associated with the one or more alarm criteria of at least one of the alarm conditions;

in response to determining that the one or more alarm criteria associated with a first alarm condition is satisfied, activating an alarm corresponding to the first alarm condition; and

transmitting, to a peripheral device, peripheral activation data associated with the first alarm condition.

25. A dialysis system comprising

a monitoring circuit configured to identify an alarm condition of the dialysis machine, the alarm condition identified based on one or more criteria associated with the alarm condition, and the alarm condition associated with peripheral activation data;

and

an alarm circuit configured to transmit the peripheral activation data to a peripheral device based on the identified alarm condition, the peripheral activation data comprising data to cause the peripheral device to operate in a mode of the peripheral device relevant to the alarm condition.

26. The dialysis system of claim 25, wherein the alarm condition is an indication that a component of the dialysis system may be malfunctioning, and the mode of the peripheral device comprises providing feedback drawing attention to the component of the dialysis system.

27. The dialysis system of claim 26, wherein providing feedback drawing attention to the component of the dialysis system comprises illuminating the component of the dialysis system.

28. The dialysis system of claim 25, further comprising a plurality of peripheral devices that are configured to receive peripheral activation data from the alarm circuit.

29. The dialysis system of claim 28, wherein at least one of the peripheral devices is configured to wake a patient upon receiving the peripheral activation data and at least one of the peripheral devices is configured to draw the patient'"'"'s attention to a particular part of the system upon receiving the peripheral activation data.

30. The dialysis system of claim 29, wherein the at least one peripheral device that is configured to wake the patient comprises a speaker and/or a light directed to the patient, and the at least one peripheral device that is configured to draw the patient'"'"'s attention to a particular part of the system comprises a light directed to the particular part of the system.

31. The dialysis system of claim 28, wherein at least one of the peripheral devices is configured to transmit information to a remote location upon receiving the peripheral activation data.

35. The dialysis system of claim 25, wherein the peripheral device is in wireless communication with the dialysis machine.

37. The dialysis system of claim 25, wherein the alarm condition is indicative of a condition of a disposable component of the dialysis system.

38. The dialysis system of claim 37, wherein the alarm condition is indicative of a malfunction of the disposable component.
