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. 11,857,504.

Summary of the Inventive Concept

An improved patient-controlled liquid oral medicine dispenser and deactivation system that ensures safe, efficient, and secure medication administration, addressing the limitations of existing invasive and non-invasive modes of delivery.

Background and Problem Solved

The original patent, 'Patient-controlled liquid oral medicine dispenser and deactivation system,' introduced a non-invasive approach to medication administration. However, it still had inherent limitations, such as the risk of overfilling, potential diversion, and lack of real-time monitoring. The new inventive concept builds upon the original patent by incorporating advanced features that overcome these limitations, providing a more reliable, efficient, and secure system for patients and healthcare professionals.

Detailed Description of the Inventive Concept

The enhanced system comprises a dosing container with automatic shut-off upon reaching the defined volumetric capacity, preventing overfilling. A real-time monitoring system tracks medication administration and detects potential diversion attempts. The suction apparatus is designed with an anti-tampering feature to prevent unauthorized access to the liquid medicine. Additionally, a sealed waste receptacle automatically detects and responds to tampering or diversion attempts. A remote monitoring and control system enables secure communication and centralized tracking of medication administration.

Novelty and Inventive Step

The new claims introduce novel features that significantly improve the original patent's functionality, including automatic shut-off, real-time monitoring, anti-tampering, and remote monitoring. These advancements provide a non-obvious solution to the limitations of the original patent, ensuring a safer, more efficient, and more secure medication administration system.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include variations in the design of the dosing container, suction apparatus, and sealed waste receptacle. For example, the dosing container could be adapted for different types of medications or patient populations. The suction apparatus could be designed with varying levels of anti-tampering complexity. The sealed waste receptacle could be integrated with different types of sensors or alarm systems to detect tampering or diversion attempts.

Potential Commercial Applications and Market

The enhanced patient-controlled liquid oral medicine dispenser and deactivation system has significant commercial potential in the healthcare industry, particularly in hospitals, clinics, and pharmacies. The system's advanced features and improved safety profile make it an attractive solution for healthcare professionals and patients alike, addressing a significant unmet need in medication administration.
