ENHANCED PATCH PUMP AND COMBINATION CONTROL SYSTEMS WITH ALARM ANNUNCIATION AND PRIORITIZATION AND BIHORMONAL VERSIONS WITH GLUCAGON

Smart overview of the Invention

The patent application introduces the iLet BIONIC PANCREAS system, which enhances alarm annunciation and prioritization in medical devices. This system integrates multiple features, including improvements in alarm management, glucagon response learning, and real-time data sharing. The system aims to provide a seamless user experience by integrating the iLet APP with the iLet BIONIC PANCREAS and various patch pump embodiments.

Key Features

The invention includes novel tubeless insulin pumps with a three-day wear time and a 12-hour grace period. These pumps can hold at least 200 units of insulin and are controlled via smartphones. They are reusable, charge-free, and feature automatic pairing. A 4.5 mm cannula is used for insertion, triggered by a button. Alarms for non-critical functions are managed to prevent disruption in insulin flow, ensuring reliability in insulin delivery.

Improved Error Management

Traditional systems often halt insulin delivery due to minor errors like speaker malfunctions, which can lead to significant issues. The iLet system addresses this by maintaining insulin delivery even when such errors are detected. Users are notified of the issue and prompted to contact customer service for a replacement, allowing continued use without switching to alternative insulin delivery methods.

Technological Integration

The patent outlines a paradigm shift where patch pumps incorporate advanced software and logic structures for adaptive learning. This integration allows for simplified access to third-party systems and includes instructions for filling and priming the patch pump. The system aims to replace the need for prior mechanisms to drive fluid from pumps, offering a versatile solution for diabetes therapy and other applications.

Innovative Mechanisms

The invention utilizes a clutch mechanism for efficient engagement between the leadscrew and the nut, reducing the need for rotation and ensuring proper priming of the fluid path. This mechanism allows for adjustments in thread pitch for various drug applications without redesigning existing components. The system enhances power management for both rechargeable and non-rechargeable devices, improving the overall efficiency of fluid delivery methods.
