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. 11,857,383.

Summary of the Inventive Concept

The present disclosure provides an enhanced washing appliance for medical devices, incorporating advanced features such as drying, UV sterilization, and monitoring capabilities to improve efficiency, safety, and accountability in medical device washing.

Background and Problem Solved

The original patent provides a washing appliance for medical devices, but it has limitations in terms of drying and sterilization capabilities, which can lead to bacterial growth and cross-contamination. The new inventive concept addresses these limitations by incorporating advanced features that enhance the washing process, making it faster, safer, and more efficient.

Detailed Description of the Inventive Concept

The enhanced washing appliance comprises a drying module with a heat source and a fan for drying medical devices after washing, reducing the risk of bacterial growth. Additionally, the appliance includes a UV light sterilization module for sterilizing devices after washing, reducing the risk of cross-contamination. The appliance also features a monitoring system that tracks device identity, monitors washing parameters, and generates a report of the washing process, increasing accountability and traceability. The inventive concept also encompasses a method for washing medical devices using the enhanced washing appliance, comprising pre-treating devices with an enzymatic solution, washing with a detergent solution, and rinsing with sterile water, increasing cleaning efficiency. Furthermore, the concept includes a washing appliance system comprising multiple washing appliances connected in series, each performing a specific cleaning step, increasing throughput and efficiency.

Novelty and Inventive Step

The new inventive concept's advanced features, including drying, UV sterilization, and monitoring capabilities, are novel and non-obvious compared to the original patent. The combination of these features provides a significant improvement in medical device washing, making the inventive concept eligible for patent protection.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include varying the design of the drying module, using different types of UV light for sterilization, or incorporating additional monitoring features. Variations could also include adapting the washing appliance for specific types of medical devices or integrating the appliance with existing hospital infrastructure.

Potential Commercial Applications and Market

The enhanced washing appliance has significant commercial potential in the medical device industry, particularly in hospitals and healthcare facilities. The inventive concept's advanced features address a critical need for improved medical device washing, and its potential market includes hospitals, medical device manufacturers, and healthcare providers.
