Abstract
Disclosed herein are methods 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, a smartphone or other remote consumer electronic device and/or a dedicated remote controller for the infusion pump. In order to ensure reliable communication of data, more than one component in a system can be capable of relaying data to another component.
Core Innovation
The invention relates to coordinating wireless communications in an infusion pump system that includes an infusion pump, a remote control device, and a continuous glucose monitoring system. The continuous glucose monitoring system transmits CGM data to the infusion pump, and the infusion pump determines therapy parameters using the CGM data. The problem addressed is disruption in wireless communication that prevents the pump from continuing therapy parameter determination based on the CGM data.
To address loss of CGM reception, the remote control device determines that the infusion pump is no longer receiving the CGM data communicated by the continuous glucose monitoring system. The remote control device communicates with the infusion pump at regular intervals to determine whether the infusion pump is receiving the CGM data. Based on this determination, the remote control device receives the CGM data from the continuous glucose monitoring system only when it has been determined that the infusion pump is no longer receiving the CGM data.
After receiving the CGM data only under the condition that the infusion pump is no longer receiving it, the remote control device relays the CGM data to the infusion pump to enable the infusion pump to continue to determine therapy parameters utilizing the CGM data while the infusion pump is no longer receiving the CGM data from the continuous glucose monitoring system. When the remote control device determines that the infusion pump resumes receiving the CGM data, the remote control device stops relaying the CGM data to the infusion pump.
Claims Coverage
The document contains three independent claims that share a common inventive concept: a remote control device monitors infusion pump reception of CGM data, conditionally receives CGM data, and relays it to the infusion pump to maintain therapy parameter determination during periods when the pump is no longer receiving the CGM data. Each independent claim includes regular-interval communication as part of determining loss of CGM reception.
Conditional CGM reception and relaying based on loss of pump reception
The remote control device receives the CGM data from the continuous glucose monitoring system only when it has been determined that the infusion pump is no longer receiving the CGM data, and relays the CGM data received from the continuous glucose monitoring system to the infusion pump to enable the infusion pump to continue to determine therapy parameters utilizing the CGM data while the infusion pump is no longer receiving the CGM data.
Remote determination of loss of CGM data reception using regular-interval communication
Determining that the infusion pump is no longer receiving the CGM data includes the remote control device communicating with the infusion pump at regular intervals to determine if the infusion pump is receiving the CGM data.
Monitoring the connection to determine whether the infusion pump is receiving CGM data
Monitoring, by the remote control device, a connection between the infusion pump and the continuous glucose monitoring system to determine whether the infusion pump is receiving CGM data from the continuous glucose monitoring system.
Control device configured to perform remote CGM connection monitoring and conditional CGM relaying
A control device including a processor configured to wireless communicate with the infusion pump system and the continuous glucose monitoring system, where the processor is configured to monitor a connection between the infusion pump and the continuous glucose monitoring system to determine whether the infusion pump is receiving CGM data, determine that the infusion pump is not receiving the CGM data, receive the CGM data only when it has been determined that the infusion pump is no longer receiving the CGM data, and relay the CGM data received to the infusion pump, wherein determining that the infusion pump is no longer receiving the CGM data includes the remote control device communicating with the infusion pump at regular intervals to determine if the infusion pump is receiving the CGM data.
Across the independent claims, the coverage focuses on remote monitoring of CGM data reception by the infusion pump, conditional reception of CGM data at the remote control device only during pump non-reception, and relaying of that CGM data to the infusion pump to allow continued therapy parameter determination, with regular-interval communication used to determine loss of reception.
Stated Advantages
Enables the infusion pump to continue to determine therapy parameters utilizing the CGM data while the infusion pump is no longer receiving the CGM data from the continuous glucose monitoring system.
Stops relaying CGM data when it has been determined that the infusion pump has resumed receiving the CGM data.
