Insulet has filed a patent for an infusion pump system that can adjust alarm limits based on the user’s insulin load. The system can also provide missed bolus or missed meal alarms based on the user’s blood glucose characteristics. The system includes a disposable pump device and a portable controller device that wirelessly receives information from a glucose monitoring device. The controller device displays the user’s current glucose value, indicates whether the glucose level is rising or falling, and shows the amount of insulin previously delivered to the user.

Infusion pump system with adjustable alarm limits and missed bolus alarm
A recently filed patent (Publication Number: US20230310744A1) describes an infusion pump system for the delivery of insulin to a user. The system consists of a disposable, non-reusable pump device with a cartridge to contain the insulin, and a portable, reusable controller device that communicates with the pump device to control its operation. The pump device can be easily attached and detached from the controller device.
The controller device is designed to wirelessly receive information from a glucose monitoring device. It can determine the amount of insulin previously delivered to the user but not yet acted upon by the user's body. This includes both bolus delivery (a single dose of insulin) and basal delivery (continuous insulin delivery). The controller device has a display that simultaneously shows the user's current glucose value, an indication arrow to indicate whether the glucose level is rising or falling, and the amount of insulin previously delivered but not yet acted upon.
The amount of insulin previously delivered but not yet acted upon can be used to predict the user's future blood glucose level. It can also be used to calculate a suggested dose of insulin to deliver to the user. The controller device determines this amount on a periodic basis and stores the information received from the glucose monitoring device, along with associated time values, in a computer-readable memory device.
The controller device is equipped with an alarm system that can detect patterns of information from the glucose monitoring device indicative of a missed insulin bolus or missed food intake. When such patterns are detected, the controller device can output an alarm and prompt the user for corrective action.
Overall, this patent describes an infusion pump system that offers improved control and monitoring of insulin delivery for users. The system's ability to wirelessly receive information from a glucose monitoring device and calculate the amount of insulin previously delivered but not yet acted upon provides valuable insights for managing diabetes. The system's alarm system and prompts for corrective action further enhance user safety and adherence to insulin therapy.
