This technical disclosure describes improvements that would be readily apparent to a Person Having Ordinary Skill In The Art (PHOSITA) when considered in combination with the foundational architecture disclosed in U.S. Patent No. 11,857,756.

Summary of the Inventive Concept

The present invention relates to an improved rotational metering pump for insulin infusion, featuring advanced sensors, adaptive algorithms, and wireless connectivity to enhance safety, accuracy, and patient convenience.

Background and Problem Solved

The original patent, 'Rotational metering pump for insulin patch', provided a foundational design for wearable medication infusion patches. However, the existing design had limitations, such as the potential for inaccurate dosing due to changes in fluid viscosity or temperature, and the lack of real-time monitoring and control. The new inventive concept addresses these limitations by integrating advanced sensors, adaptive algorithms, and wireless connectivity to ensure accurate and safe insulin delivery.

Detailed Description of the Inventive Concept

The enhanced rotational metering pump features an integrated pressure sensor to monitor fluid pressure during delivery, allowing for real-time adjustments to pump speed. The pump is also equipped with an adaptive pumping algorithm that adjusts pump speed and stroke volume based on real-time feedback from a built-in accelerometer and gyroscope, ensuring accurate dosing during patient movement. Additionally, the pump features interchangeable cartridges, each containing a different insulin formulation or concentration, and a control unit that automatically detects and adjusts to the specific cartridge inserted. The pump is powered by a compact, low-power design with a self-contained power source and wireless connectivity for remote monitoring and control.

Novelty and Inventive Step

The new inventive concept introduces several novel features, including the integration of advanced sensors, adaptive algorithms, and wireless connectivity, which provide a significant improvement over the original patent. The inventive step lies in the combination of these features, which enables accurate and safe insulin delivery, while also enhancing patient convenience and comfort.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include variations in sensor types, algorithm designs, and connectivity protocols. For example, the pump could be designed with a built-in glucose sensor to provide real-time glucose monitoring, or with a different type of wireless connectivity, such as Bluetooth or NFC. Additionally, the pump could be adapted for use with other types of medications or fluids.

Potential Commercial Applications and Market

The enhanced rotational metering pump has significant commercial potential in the diabetes management market, where there is a growing need for accurate, convenient, and connected insulin delivery systems. The inventive concept could be licensed to insulin pump manufacturers, or developed into a proprietary product for Becton, Dickinson and Company. The target market includes patients with diabetes, as well as healthcare providers and payers seeking to improve patient outcomes and reduce healthcare costs.
