Abstract

A battery-powered infusion pump for delivery of insulin or other medicament may collect and store data related to the pump. The infusion pump can communicate some or all of the stored data to another device, and control the timing and amount of data communicated in order to conserve battery life.

Claims

1. An infusion pump, comprising:

a battery;

a data storage means;

a wireless communication means configured to communicate data related to therapy provided by the infusion pump to another device; and

a processor configured to;

collect and store the data related to therapy provided by the infusion pump in the data storage means; and

control communication of the data related to therapy provided by the infusion pump to another device so as to reduce energy consumption of the battery based on information contained in the data storage means by controlling how often the data related to therapy provided by the infusion pump is communicated to the another device,

wherein the processor is configured to control the communication of the data to the other device based on occurrence of a predetermined event, and

wherein the predetermined event is selected from a group consisting of a bolus delivery, a change in basal delivery rate, and an alarm.

2. The infusion pump of claim 1, wherein the processor is configured to communicate an indication of status of the infusion pump as part of the data.

3. The infusion pump of claim 1, wherein the processor is configured to only transmit part of the stored data to the other device.

4. The infusion pump of claim 3, wherein the processor is configured to transmit additional stored data upon connection of the infusion pump to an external power source.

5. The infusion pump of claim 1, wherein the processor is configured to control the communication of the data based on a physical location of the infusion pump.

6. The infusion pump of claim 1, wherein the communication is via Bluetooth connection.

7. The infusion pump of claim 1, further comprising a connector configured for interfacing with an external power source.

8. A method of reducing energy consumption of a battery of an infusion pump, the method comprising:

collecting data related to the infusion pump;

storing the data in a data storage means in the infusion pump;

wirelessly communicating the data to another device; and

controlling communication of the data so as to reduce energy consumption of the battery based on information contained in the data storage means by controlling how often the data is communicated to the another device,

wherein controlling communication of the data is based on occurrence of a predetermined event, and

wherein the predetermined event is selected from a group consisting of a bolus delivery, a change in basal delivery rate, and an alarm.

9. The method of claim 8, wherein communication of the data includes communicating an indication of status of the infusion pump.

10. The method of claim 8, wherein controlling communication of the data comprises transmitting less than all of the stored data to the other device.

11. The method of claim 10, further comprising transmitting additional data upon connection of the infusion pump to an external power source.

12. The method of claim 8, wherein controlling communication of the data is based on a physical location of the infusion pump.

13. The method of claim 8, wherein communication of the data is via Bluetooth connection.
