Abstract

An apparatus comprising a pump, an input configured to receive information related to a user, a user interface, and a controller communicatively coupled to the pump, the input, and the user interface. The controller includes a timing module configured to initiate delivery of a drug in time and to adjust delivery according to the received information. Other devices, systems, and methods are disclosed.

Claims

1. An apparatus comprising:

a pump configured to deliver a drug from a cartridge;

a user interface;

a memory to store guideline parameters related to use of the apparatus; and

a controller communicatively coupled to the pump, the memory, and the user interface, wherein the controller includes;

a comparison module configured to compare patient use parameters to the stored guideline parameters; and

a scoring module configured to calculate a score indicative of efficacy of patient pump use based on a comparison by the comparison module, and

wherein the controller is configured to communicate advice to the user on how to increase the efficacy of patient pump use.

6. The apparatus of claim 1, wherein the comparison module is configured to compare a frequency of entering user information into the device to a stored frequency.

7. The apparatus of claim 1, wherein the comparison module is configured to compare at least one of:

a frequency of cartridge changes to a stored cartridge change frequency value,

a frequency of infusion set changes to a stored set change frequency value,

a difference in timing of cartridge changes to a stored threshold change time difference value, or

a frequency that cartridges are allowed to empty to a stored empty cartridge frequency value.

8. The apparatus of claim 1, wherein the comparison module is configured to compare at least one of:

a frequency of using test features of the pump device to a stored test frequency value,

a total tune that the pump device is inoperative to a stored total time value,

a frequency that a pump generated report is viewed to a stored report-view frequency value, or

a time from when an alert is generated by the device to a time when a user responds to the alert to a stored response time value.

9. The apparatus of claim 1, wherein the user interface includes a display, wherein the scoring module is configured to trend the score, and wherein the controller is configured to display the score and score trend on the device.

10. The apparatus of claim 1, wherein calculating a score based on the monitored patient use includes assigning different weights to outcomes of comparisons of use parameters to guideline parameters when calculating the score.

11. The apparatus of claim 1, including a communication port communicatively coupled to the controller, and wherein the controller is configured to communicate the advice on how to increase pump efficacy to a second separate device.

2. The apparatus of claim including:

an input communicatively coupled to the controller and configured to receive user information, including a level of user information, and

wherein the comparison module is configured to monitor the level of the user information.

3. The apparatus claim 2, including a communication port communicatively coupled to the input and configured to receive user information from a second separate device.

4. The apparatus of claim 2, wherein the user interface includes a display, and wherein the controller is configured to prompt the user, via the display, to begin a measurement using a separate device.

5. The apparatus of claim 2, wherein the user interface is configured to receive manual entry of the information from the user.

12. A method comprising:

monitoring patient use of a device that includes a pump with an electronic controller communicatively coupled to the pump, wherein the monitoring includes comparing patient use parameters to stored guideline parameters;

calculating a score indicative of efficacy of patient pump use with the controller based on the monitoring of the controller; and

communicating advice to the user on how to increase pump efficacy with the controller.

13. The method of claim 12, including receiving patient information into the device, and wherein monitoring patient use includes monitoring the patient information.

14. The method of claim 12, wherein comparing patient use parameters to stored guideline parameters includes comparing a frequency of entering readings into the device to a stored frequency.

15. The method of claim 12, wherein comparing patient use parameters to stored guideline parameters includes comparing at least one of:

a frequency of cartridge changes to a stored change frequency value,

a difference in timing of cartridge changes to a stored threshold cartridge change time difference value,

a difference in timing of infusion set changes to a stored threshold infusion set change time difference value, or

a frequency that cartridges are allowed to empty to a stored empty cartridge frequency value.

16. The method of claim 12, wherein comparing patient use parameters to stored guideline parameters includes comparing at least one of:

a frequency of using test features of the pump device to a stored test frequency value,

a total time that the pump device is inoperative to at stored total time value,

a frequency that a pump generated report is viewed to a stored report-view frequency value, or

a time from when an alert is generated by the device to a time then a user responds to the alert to a stored response time value.

17. The method t of claim 12, wherein calculating a score based on the monitored patient use includes assigning different weights to outcomes of the comparing when calculating the score.

18. The method of claim 12, including:

trending the score; and

displaying the score and a score trend on the device.

19. The method of claim 12, wherein communicating advice includes communicating advice on how to increase pump efficacy to a second separate device.
