Enhanced Rotational Metering Pump for Wearable Insulin Infusion Patches

An advanced rotational metering pump system for wearable insulin infusion patches, featuring improved safety, efficiency, and user experience through innovative enhancements.

The original patent for the rotational metering pump for insulin patches, while effective, had limitations in terms of fluid pressure monitoring, user insulin sensitivity, temperature control, and redundant fluid paths. The new inventive concept addresses these limitations by introducing a pressure sensor, adaptive pump speed, temperature control, redundant fluid paths, and data analytics.

The enhanced rotational metering pump system comprises a fluid reservoir, cannula assembly, pressure sensor, and adaptive pump speed control. The pump speed is adjusted based on the user's insulin sensitivity profile, ensuring optimal insulin delivery. A temperature control mechanism maintains a consistent fluid temperature during delivery, while a redundant fluid path ensures continuous delivery in case of primary path failure. A data analytics module tracks and analyzes user insulin delivery patterns, providing valuable insights for improved disease management.

The new inventive concept's novelty lies in the integration of a pressure sensor, adaptive pump speed control, temperature control, redundant fluid paths, and data analytics, which collectively provide a safer, more efficient, and user-centric insulin delivery system. These enhancements are non-obvious compared to the original patent and demonstrate a significant inventive step.

Alternative embodiments may include varying the pressure sensor design, incorporating additional sensors for glucose monitoring, or using alternative materials for the fluid reservoir and cannula assembly. Variations may also include different temperature control mechanisms or data analytics algorithms to further optimize insulin delivery.

The enhanced rotational metering pump system has significant commercial potential in the wearable insulin infusion patch market, offering improved safety, efficiency, and user experience. The system can be marketed to pharmaceutical companies, medical device manufacturers, and healthcare providers, targeting patients with diabetes and other chronic diseases requiring insulin therapy.
