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. 11,857,757.

Summary of the Inventive Concept

The inventive concept leverages the core technology of wearable patch pumps to deliver microdoses of personal care products, nutraceuticals, and fragrances, enabling targeted and controlled administration for various applications.

Background and Problem Solved

The original patent focused on wearable insulin pumps for diabetes management. However, the limitations of these devices in terms of size, complexity, and user experience hinder their adoption in other industries. The new inventive concept addresses these limitations by adapting the core technology to cater to emerging markets and use cases.

Detailed Description of the Inventive Concept

The microdose delivery system consists of a wearable patch pump, a product cartridge, and a controller. The patch pump is designed to dispense precise amounts of the product through a transcutaneous portion. The controller regulates the dosage and frequency of delivery based on user input, sensor data, or predetermined settings. The system can be tailored for various applications, including skincare, haircare, makeup, fragrance delivery, and nutraceutical administration.

Novelty and Inventive Step

The new claims introduce the concept of microdose delivery for personal care and wellness, which is not anticipated by the original patent. The inventive step lies in the adaptation of the wearable patch pump technology to cater to these new applications, requiring modifications to the pump design, product cartridges, and control algorithms.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include varying patch pump designs, different product cartridges, and modifications to the control algorithms. Additionally, the system could be integrated with wearable sensors, mobile applications, or artificial intelligence to enhance user experience and personalize delivery.

Potential Commercial Applications and Market

The microdose delivery system has significant commercial potential in the personal care, wellness, and nutraceutical industries. Target markets include skincare, haircare, and fragrance companies, as well as nutraceutical manufacturers. The system's ability to provide targeted and controlled administration of products could revolutionize the way consumers interact with these industries.
