Abstract
Enclosed herein are methods and systems for establishing communication protocols between wireless devices in infusion pump systems. Infusion pump systems can include a number of components capable of wireless communication with one or more other components including an infusion pump, a continuous glucose monitoring (CGM) system, and a smartphone or other multi-purpose consumer electronic device (i.e., remote control device). Communications among these devices can be coordinated to ensure reliable and consistent transmission of medical data.
Core Innovation
The described invention relates to coordinating wireless communications in an infusion pump system that includes a continuous glucose monitoring (CGM) device and an infusion pump. The method initiates a communication session between the infusion pump and the CGM device and determines that the infusion pump is communicatively coupled to the CGM device. The communication signal quality is determined as a function of relative positioning of the infusion pump and the CGM device with respect to the body of the user.
The invention determines a first location of the infusion pump relative to a body of a user and determines a first location of the CGM device relative to the body of the user. Based on the relative positioning between the first location of the infusion pump and the first location of the CGM device, the method determines a measurement of communication signal quality between the infusion pump and the CGM device. The communication signal quality measurement is linked to where the devices are positioned on the user's body.
The disclosed approach supports user-facing indications tied to the relative positioning and the signal strength measurement. The system provides guidance and interface indications that can include displaying communication signal quality measurements on a graphical representation of the user's body and supporting real-time updates when devices are moved. The guidance can include recommending a location for one or more of the devices based on the measure of signal strength and, for the infusion pump, on predicted efficacy of insulin absorption at the recommended location.
Claims Coverage
The provided material includes two independent claims. Across them, the coverage centers on initiating and coordinating a pump-to-CGM communication session using relative body positioning to measure signal quality/strength, and then using that measurement to drive user interface guidance for positioning.
Location-dependent measurement of communication signal quality
Initiating a communication session between the infusion pump and the CGM device; determining that the infusion pump is communicatively coupled to the CGM device; determining a first location of the infusion pump relative to a body of a user; determining a first location of the CGM device relative to the body of the user; and determining a measurement of communication signal quality between the infusion pump and the CGM device as a function of a relative positioning of the first location of the infusion pump and the first location of the CGM device with respect to the body of the user.
User-interface guidance for device positioning based on signal strength
Receiving input through a user interface from a user initiating a communication session between the infusion pump and the CGM device; and providing guidance on the user interface to the user on where to position at least one of the infusion pump and the CGM device relative to a body of the user based on a measure of signal strength between the infusion pump and the CGM device based on a relative position of the infusion pump and the CGM device with respect to the body of the user.
Overall, the claim coverage coordinates pump-to-CGM wireless communications by linking communication signal quality/strength to relative device positions on a user's body, and then uses the resulting measure to provide user interface guidance for positioning the devices, optionally including signal-quality indications and location recommendations informed by additional criteria.
Stated Advantages
Provides user-interface guidance on where to position the infusion pump and/or CGM device relative to the user's body based on a measure of signal strength.
Enables user interface indication of communication signal quality measurement as acceptable or not acceptable based on a predetermined threshold.
Supports recommending moving at least one of the infusion pump and the CGM device to a second location when the measured communication signal quality is below a predetermined threshold.
Supports visual guidance by displaying communication signal quality measurements on a graphical representation of the user's body.
Optionally supports location recommendation for an infusion pump based on predicted efficacy of insulin absorption at that location.
Documented Applications
Guiding a user to position an infusion pump and a CGM device to achieve or maintain wireless communication signal quality between the devices.
Providing user interface indications and guidance during initiation of a communication session between an infusion pump and a CGM device.
