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. 11,857,708.

Summary of the Inventive Concept

An innovative device and system for attachment to injection devices, providing real-time dosage detection, audible and visual feedback, and automated adjustments to enhance user experience and accuracy.

Background and Problem Solved

The original patent, 'Device for attachment to an injection device', addressed the need for a supplementary device to detect and select dosages for injection. However, it had limitations in providing real-time feedback, tracking dosage information, and adjusting injection depth. The new inventive concept solves these limitations by introducing an intelligent system that detects and provides feedback on the selected dosage, enabling users to make accurate injections.

Detailed Description of the Inventive Concept

The new inventive concept comprises a device for attachment to an injection device, configured to detect a selected dosage for injection and provide an audible and visual indication of the selected dosage. The device includes a mechanical coupling to transfer the torque from the dial knob to the release button of the drug delivery device, ensuring accurate dosage selection. Additionally, the device can transmit the selected dosage information to a remote server for tracking and storage in a patient-specific database. The system also includes a method for improving the accuracy of dosage selection by providing real-time feedback to the user. Furthermore, the device can automatically adjust the injection depth based on the selected dosage, enhancing user experience and accuracy.

Novelty and Inventive Step

The new claims introduce the novelty of providing real-time feedback and automated adjustments to the injection process, which is not present in the original patent. The inventive step lies in the integration of mechanical coupling, audible and visual indication, and automated adjustments to create an intelligent dosage detection and feedback system.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include the use of different mechanical coupling mechanisms, such as gears or levers, or the integration of additional sensors to detect other parameters, such as injection speed or pressure. Variations of the system could also include the use of different types of injection devices or the development of a standalone device for dosage detection and feedback.

Potential Commercial Applications and Market

The intelligent dosage detection and feedback system has significant commercial potential in the pharmaceutical and medical industries, particularly in the development of injectable medications and insulin delivery systems. The system's ability to enhance user experience, accuracy, and safety makes it an attractive solution for patients and healthcare professionals alike.
