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.
Core Innovation
An ambulatory infusion pump stores and communicates data related to therapy provided by the infusion pump to another device. The pump detects occurrence of a predetermined event related to an operation of the infusion pump, determines a priority assigned to the predetermined event, and controls communication of the therapy-related data to the other device based at least on the priority assigned to the predetermined event. The pump includes a wireless communication interface that, in accordance with the priority assigned to the predetermined event, communicates the data related to therapy provided by the infusion pump to the other device.
Communication behavior is driven by the priority assigned to the predetermined event. The pump can communicate different portions of stored therapy-related information, including a partial subset of stored data and full saved data, depending on the priority and context of the event and communication. Priority-based wireless exchanges include event-based communication and time/periodic communication.
Communication behavior is also conditioned on power and event circumstances. The pump can delay communication of therapy-related data to the other device until the infusion pump is connected to an external power source when a predetermined event is determined to have relatively lower priority. Low-power Bluetooth advertising packets can be used to indicate when the phone should initiate a data transfer.
Claims Coverage
The partial set includes three independent claims. Across the independent claims, the core coverage is an event-detection and priority determination controlling priority-based wireless communication of therapy/operation data to another device, with a wireless interface used in accordance with the assigned priority.
Priority-based communication of therapy data
An infusion pump detects occurrence of a predetermined event related to an operation of the infusion pump, determines a priority assigned to the predetermined event, and responsive to the occurrence controls communication of data related to therapy provided by the infusion pump to another device based at least on the priority assigned to the predetermined event; and a wireless communication interface configured to, in accordance with the priority assigned to the predetermined event, communicate the data related to therapy provided by the infusion pump to the other device.
Priority-based wireless communication method
A method detects occurrence of a predetermined event related to an operation of an infusion pump; determines a priority assigned to the predetermined event; responsive to the occurrence controls communication of data related to therapy provided by the infusion pump to another device based at least on the priority assigned to the predetermined event; and in accordance with the priority wirelessly communicates the data related to therapy provided by the infusion pump to the other device.
Priority-based communication of medical device operation data
A medical device includes a processor configured to detect occurrence of a predetermined event related to the medical device, determine a priority assigned to the predetermined event, and responsive to the occurrence control communication of data related to one or more operations of the medical device to another device based at least on the priority assigned to the predetermined event; and a wireless communication interface configured to, in accordance with the priority assigned to the predetermined event, communicate the data related to one or more operations of the medical device to the other device.
All independent claims require detecting occurrence of a predetermined event, determining a priority assigned to the predetermined event, and controlling wireless communication of therapy/operation-related data to another device in accordance with the assigned priority.
Stated Advantages
Reduces power usage associated with communications by conserving phone-to-cloud transfers and controlling wireless exchanges based on priority and context.
Documented Applications
Communicating ambulatory infusion pump therapy data to a smartphone/another device based on priority and event-related context, including event-based, time-based/periodic, proximity/GPS-based triggering, and partial versus full data transfer.
Priority-driven communication of example pump events such as bolus delivery, basal-rate changes, and alarms.
