Abstract

Insulin delivery systems include a first insulin pump and a second insulin pump, wherein each pump includes a memory configured to store an infusion program, a control unit configured to control operation of the pump, and a communication interface for data exchange with the other pump, wherein the control unit of the first insulin pump is configured monitor, a status of the first insulin pump, activate a search for the presence of the second insulin pump when a predetermined status is assumed, and, upon detection of the presence of the second insulin pump, transmit, via the communication interface of the first insulin pump, the infusion program stored, and the control unit of the second insulin pump is configured to search for the presence of the first insulin pump, and, upon detection of the presence of the first insulin pump, receive and store, the infusion program.

Claims

1. An insulin delivery system comprising a first insulin pump and a second insulin pump, wherein each of the first insulin pump and the second insulin pump comprises:

a memory configured to store an infusion program;

a control unit configured to control operation of the insulin pump; and

a communication interface for data exchange with the other of the first insulin pump and the second insulin pump;

wherein the control unit of the first insulin pump is configured to autonomously perform the steps of;

monitoring, during operation of the first insulin pump according to the infusion program, a status of the first insulin pump;

activating a search for the presence of the second insulin pump when a predetermined status is assumed by the first insulin pump, and, upon detection of the presence of the second insulin pump; and

transmitting, via the communication interface of the first insulin pump, the infusion program stored in the memory of the first insulin pump to the second insulin pump; and

the control unit of the second insulin pump is configured to perform the steps of;

searching for the presence of the first insulin pump, and, upon detection of the presence of the first insulin pump, performing the steps of;

receiving, via the communication interface of the second insulin pump, an infusion program from the first insulin pump; and

storing the infusion program in the memory of the second insulin pump.

2. The insulin delivery system of claim 1, wherein the first insulin pump and the second insulin pump are identical insulin pumps.

3. A method for replacing a first insulin pump by a second insulin pump, the method comprising:

operating the first insulin pump according to an infusion program stored in a memory of the first insulin pump; and

controlling the first insulin pump to autonomously perform the steps of;

activating a search for the presence of the second insulin pump, and, upon detection of the presence of the second insulin pump; and

transmitting, via communication interfaces of the first insulin pump and the second insulin pump, the infusion program from the first insulin pump to the second insulin pump.

4. An insulin pump comprising:

a communication interface for data exchange with a replacement pump;

a memory configured to store an infusion program; and

a control unit configured to control operation of the insulin pump, wherein the control unit is further configured to autonomously perform the steps of;

monitoring, during operation of the infusion pump according to the infusion program, a status of the insulin pump;

activating a search for the presence of the replacement pump when a predetermined status is assumed by the insulin pump; and

transmitting, upon detecting the presence of the replacement pump, via the communication interface, the infusion program stored in the memory to the replacement pump.

5. The insulin pump of claim 4, wherein the status monitored by the control unit comprises at least one of a filling state of an insulin reservoir of the insulin pump, the status of a battery of the insulin pump, and an error status of the insulin pump.

6. The insulin pump of claim 4, wherein the control unit is further configured to control the insulin pump to continue insulin delivery while a search for the presence of the replacement pump is active.

7. The insulin pump of claim 4, wherein the control unit is further configured to control the insulin pump to terminate operation after successful transmission of the infusion program to the replacement pump.

8. The insulin pump of claim 4, wherein the insulin pump comprises, in addition to the wireless communication interface, a device for detecting the presence of the replacement pump.

9. The insulin pump of claim 4, wherein the insulin pump is further configured to receive the infusion program from a remote controller.

10. The insulin pump of claim 4, wherein the control unit is further configured to indicate, via an indicator of the insulin pump, at least one of the search for the replacement pump, the successful detection of the replacement pump, the successful transmission of the program to the replacement pump, or the unsuccessful transmission of the program to the replacement pump.

11. The insulin pump of claim 4, wherein the insulin pump is further configured to perform the steps of:

searching for the presence of a source pump; and

when the presence of a source pump is detected, performing the steps of;

receiving, via the communication interface, an infusion program from the source pump; and

storing the infusion program in the memory.

12. The insulin pump of claim 11, wherein the control unit is further configured to detect an insulin reservoir of the insulin pump being filled, and, upon the insulin reservoir being filled, to activate the search for a source pump.

13. The insulin pump of claim 11, wherein the control unit is further configured to control the insulin pump, after successfully having received an infusion program from the source pump, to autonomously start insulin delivery.

14. The insulin pump of claim 13, wherein the control unit is further configured to detect an insulin reservoir of the insulin pump being filled, and, upon the insulin reservoir being filled, to activate the search for a source pump.

15. The insulin pump of claim 5, wherein the control unit is further configured to control the insulin pump to continue insulin delivery while a search for the presence of the replacement pump is active.

16. The insulin pump of claim 15, wherein the control unit is further configured to control the insulin pump to terminate operation after successful transmission of the infusion program to the replacement pump.

17. The insulin pump of claim 16, wherein the insulin pump comprises, in addition to the wireless communication interface, a device for detecting the presence of the replacement pump.

18. The insulin pump of claim 17, wherein the insulin pump is further configured to receive the infusion program from a remote controller.

19. The insulin pump of claim 18, wherein the control unit is further configured to indicate, via an indicator of the insulin pump, at least one of the search for the replacement pump, the successful detection of the replacement pump, the successful transmission of the program to the replacement pump, or the unsuccessful transmission of the program to the replacement pump.
