Abstract

A system configured to synchronize the displays of multiple infusion pumps is provided. In some embodiments, the system includes a plurality of infusion pumps in communication with a server. An individual infusion pump synchronizes its internal clock by communicating with the server. Based on the synchronized internal clock, the infusion pump determines the current time, calculates a parameter based on the current time, and causes screen content corresponding to the calculated parameter to be displayed.

Claims

1. An apparatus configured to provide synchronized screen content of at least one medical device, the apparatus comprising:

a display;

an internal clock;

a processor in communication with the display and the internal clock;

a memory storing instructions that, when executed by the processor, configure the processor to;

calculate a first screen content index based on (i) a first time based on the internal clock, (ii) a content display period length indicative of a duration for which a medical device screen content is to be displayed on the display, and (iii) a screen content count indicative of a count of a plurality of medical device screen contents to be displayed on the display; and

cause a first medical device screen content of the plurality of medical device screen contents that corresponds to the calculated first screen content index to be displayed on the display for a duration that is equal to the content display period length.

2. The apparatus of claim 1, wherein the instructions, when executed by the processor, further configure the processor to, prior to causing the first medical device screen content to be displayed on the display for the duration that is equal to the content display period length, cause a second medical device screen content of the plurality of medical device screen contents to be displayed on the display for a duration that is less than the content display period length.

3. The apparatus of claim 2, wherein the display of the second medical device screen content immediately precedes the display of the first medical device screen content.

4. The apparatus of claim 2, wherein the instructions, when executed by the processor, further configure the processor to:

determine that a user input has not been received for a threshold amount of time; and

in response to the determination that the user input has not been received for the threshold amount of time, calculate a second screen content index based on (i) a second time based on the internal clock prior to the first time, (ii) the content display period length, and (iii) the screen content count; and

cause the second medical device screen content that corresponds to the calculated second screen content index to be displayed on the display.

5. The apparatus of claim 1, wherein the instructions, when executed by the processor, further configure the processor to calculate the first screen content index based on a modulo operation comprising the content display period length and the screen content count.

6. The apparatus of claim 1, wherein the instructions, when executed by the processor, further configure the processor to:

receive clock synchronization data from a server in network communication with the apparatus; and

update the internal clock based on the clock synchronization data.

7. The apparatus of claim 6, wherein the instructions, when executed by the processor, further configure the processor to transmit a clock synchronization data request to the server and receive the clock synchronization data in response to the clock synchronization data request.

8. A method of providing synchronized screen content of a medical device, the method comprising:

calculating a first screen content index based on (i) a first time based on an internal clock of the medical device, (ii) a content display period length indicative of a duration for which a medical device screen content is to be displayed on a display of the medical device, and (iii) a screen content count indicative of a count of a plurality of medical device screen contents to be displayed on the display of the medical device; and

displaying, on the display of the medical device, a first medical device screen content of the plurality of medical device screen contents that corresponds to the calculated first screen content index for a duration that is equal to the content display period length.

9. The method of claim 8, further comprising, prior to displaying the first medical device screen content on the display for the duration that is equal to the content display period length, displaying a second medical device screen content of the plurality of medical device screen contents on the display for a duration that is less than the content display period length.

10. The method of claim 9, wherein the display of the second medical device screen content immediately precedes the display of the first medical device screen content.

11. The method of claim 9, further comprising:

determining that a user input has not been received for a threshold amount of time; and

in response to determining that the user input has not been received for the threshold amount of time, calculating a second screen content index based on (i) a second time based on the internal clock prior to the first time, (ii) the content display period length, and (iii) the screen content count; and

displaying the second medical device screen content that corresponds to the calculated second screen content index on the display.

12. The method of claim 8, further comprising calculating the first screen content index based on a modulo operation comprising the content display period length and the screen content count.

13. The method of claim 8, further comprising:

receiving clock synchronization data from a server; and

updating the internal clock based on the clock synchronization data.

14. A system configured to provide synchronized screen content, the system comprising:

a server; and

a plurality of medical devices in network communication with the server, wherein each respective medical device of the plurality of medical devices comprises (i) a display configured to display one or more medical device screen contents and (ii) an internal clock, wherein the respective medical device is configured to;

calculate a first screen content index based on (i) a first time based on the internal clock, (ii) a content display period length indicative of a duration for which a medical device screen content is to be displayed on the display, and (iii) a screen content count indicative of a count of a plurality of medical device screen contents to be displayed on the display; and

cause a first medical device screen content of the plurality of medical device screen contents that corresponds to the calculated first screen content index to be displayed on the display for a duration that is equal to the content display period length.

15. The system of claim 14, wherein the respective medical device is further configured to, prior to causing the first medical device screen content to be displayed on the display for the duration that is equal to the content display period length, cause a second medical device screen content of the plurality of medical device screen contents to be displayed on the display for a duration that is less than the content display period length.

16. The system of claim 15, wherein the display of the second medical device screen content immediately precedes the display of the first medical device screen content.

17. The system of claim 15, wherein the respective medical device is further configured to:

determine that a user input has not been received for a threshold amount of time; and

in response to the determination that the user input has not been received for the threshold amount of time, calculate a second screen content index based on (i) a second time based on the internal clock prior to the first time, (ii) the content display period length, and (iii) the screen content count; and

cause the second medical device screen content that corresponds to the calculated second screen content index to be displayed on the display.

18. The system of claim 14, wherein the respective medical device is further configured to calculate the first screen content index based on a modulo operation comprising the content display period length and the screen content count.

19. The system of claim 14, wherein the respective medical device is further configured to:
