Methods for reduction of battery usage in ambulatory infusion pumps
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.
1. An infusion pump, comprising:
a battery;
a memory;
a wireless communication interface 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 memory; and
control communication of the stored data related to therapy provided by the infusion pump to another device so as to reduce energy consumption of the battery, wherein controlling communication of the stored data so as to reduce energy consumption of the battery includes selectively delaying transmission of at least some of the stored data until a predetermined condition relating to treatment with the infusion pump is met.
2. The infusion pump of claim 1 , wherein the predetermined condition is occurrence of a predetermined infusion pump therapy event.
3. The infusion pump of claim 1 , wherein the processor is configured to communicate an indication of a status of the infusion pump to the another device.
4. The infusion pump of claim 1 , wherein the processor is configured to transmit part of the stored data to the another device prior to the predetermined condition being met.
5. The infusion pump of claim 4 , wherein the processor is configured to transmit additional stored data upon the predetermined condition being met.
6. The infusion pump of claim 1 , wherein the predetermined condition is connection of the infusion pump to a power source.
7. The infusion pump of claim 1 , wherein the predetermined condition is based on a geographic location of the infusion pump.
8. The infusion pump of claim 1 , wherein the communication is via Bluetooth connection.
9. The infusion pump of claim 1 , further comprising a connector configured for interfacing with an external power source.
10. 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 memory in the infusion pump; wirelessly communicating the stored 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 memory, wherein controlling communication of the stored data so as to reduce energy consumption of the battery includes selectively delaying transmission of at least some of the stored data until a predetermined condition relating to treatment with the infusion pump is met.
11. The method of claim 10 , wherein the predetermined condition is occurrence of a predetermined infusion pump therapy event.
12. The method of claim 10 , further comprising communicating an indication of a status of the infusion pump.
13. The method of claim 10 , wherein controlling communication of the data comprises transmitting less than all of the stored data to the another device prior to the predetermined condition being met.
14. The method of claim 13 , further comprising transmitting additional data to the another device upon the predetermined condition being met.
15. The method of claim 10 , wherein the predetermined condition is connection of the infusion pump to a power source.
16. The method of claim 10 , wherein the predetermined condition is based on a geographical location of the infusion pump.
17. The method of claim 10 , wherein communication of the data is via Bluetooth connection.
