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. 11,857,295.

Summary of the Inventive Concept

This inventive concept introduces novel enhancements to connectors for medical equipment, focusing on improved accuracy, efficiency, and patient safety in hemodynamic parameter measurements.

Background and Problem Solved

The original patent, 'Connectors for medical equipment,' provides a foundation for cuff adapters in patient monitoring devices. However, these adapters can be prone to biofilm buildup, inaccurate measurements, and time-consuming calibration. This inventive concept addresses these limitations by incorporating self-cleaning mechanisms, integrated sensors, machine learning algorithms, detachable calibration modules, and wireless communication capabilities into the connector design.

Detailed Description of the Inventive Concept

The enhanced connector for medical equipment features a novel self-cleaning mechanism that prevents biofilm buildup on the connector's surface, ensuring accurate hemodynamic parameter measurements. Additionally, the cuff adapter is equipped with an integrated sensor for detecting cuff pressure and automatically adjusting the pressure to ensure accurate measurements. A machine learning algorithm can be used to analyze data from the cuff-based measurement system, providing real-time feedback on cuff inflation and deflation rates. The connector also includes a detachable module for storing calibration data and automatically updating the connector's calibration settings, reducing calibration time and increasing measurement accuracy. Furthermore, the system can be integrated with a wireless communication module for transmitting measurement data to a remote monitoring station, enabling real-time remote monitoring and improving patient care.

Novelty and Inventive Step

The new claims introduce a range of novel features that enhance the functionality and accuracy of the original cuff adapter design. The self-cleaning mechanism, integrated sensor, machine learning algorithm, detachable calibration module, and wireless communication capabilities are non-obvious improvements that address specific limitations of the original patent.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include variations in the self-cleaning mechanism, such as using ultraviolet light or enzymatic cleaning agents. The integrated sensor could be replaced with alternative sensing technologies, such as pressure sensors or flow sensors. The machine learning algorithm could be adapted for use with different types of medical equipment or patient monitoring devices. The detachable calibration module could be designed for use with multiple connectors or devices, and the wireless communication module could be integrated with various remote monitoring platforms.

Potential Commercial Applications and Market

The enhanced connector for medical equipment has significant commercial potential in the patient monitoring device market, particularly in applications where accurate hemodynamic parameter measurements are critical, such as in intensive care units, operating rooms, and emergency medical services. The inventive concept's focus on improving patient safety, reducing calibration time, and enabling real-time remote monitoring aligns with the growing demand for advanced patient monitoring technologies.
