Abstract

This document discusses, among other things, an apparatus comprising a pump configured to deliver a fluid, a wireless communication port, a controller, and a housing to enclose the apparatus. The controller is configured to communicate with a second device via the communication port using an open standard wireless communication protocol. The housing includes a mechanical coupling to slidably engage the second device which includes a second wireless communication port. Slidably engaging the second device positions the first and second communication ports opposite each other to allow communication via the first and second communication ports when slidably engaged.

Core Innovation

An insulin infusion pump system delivers insulin therapy to a user and includes a wireless communications interface and at least one processor coupled to the pump and the wireless communications interface. The processor establishes wireless communications with a user device and receives wireless communications indicating that the user is exercising, including a specific activity of the user. Based on the specific activity, the processor modifies one or more parameters of the insulin therapy while the user is exercising, where the modification is based on a category of activities that the specific activity belongs to.

The system supports activity information associated with exercise by receiving a signal representative of user activity, including activity sensing using an accelerometer or a pedometer. The user device provides the specific activity via selection of the specific activity or via detection of an activity-representative signal, and different specific activities result in different modifications of insulin-therapy parameters.

The system also includes storing therapy modifications associated with specific activities in memory, so the modification based on the specific activity is stored for the specific activity. In this way, insulin therapy changes during exercise are tied to a specific activity category and corresponding parameter modifications, communicated wirelessly between the user device and the pump system.

Claims Coverage

The partial claim set includes two independent claims that both focus on wireless communication with a user device to modify insulin-therapy parameters during exercise based on a specific activity and its categorization; one claim additionally requires storage of the modification for the specific activity in memory.

Across the independent claims, the inventive subject matter centers on wireless communications from a user device that indicate exercise and a specific activity, followed by modification of insulin-therapy parameters while the user is exercising, with the modification being based on an activity category in one claim and being stored for the specific activity in the other claim.
