Enhanced Patient Interface Device with Double-Y Supporting Structure
Legal Citation
Summary of the Inventive Concept
An improved patient interface device featuring a double-Y supporting structure, designed to enhance stability, ease of use, and overall performance in delivering breathing gas to patients.
Background and Problem Solved
The original patient interface device with a double-Y supporting structure, as described in the original patent, has limitations in terms of vibration, manufacturing complexity, and maintenance. The new inventive concept addresses these limitations by introducing a stabilizing component, 3D printing, modular architecture, pressure monitoring, and lightweight materials.
Detailed Description of the Inventive Concept
The enhanced patient interface device features a frame assembly with a double-Y supporting structure, which is augmented by a stabilizing component to reduce vibrations during gas delivery. The frame assembly can be fabricated using a 3D printing process to improve structural integrity and reduce manufacturing complexity. Additionally, the frame assembly is designed with a modular architecture to facilitate easy disassembly and cleaning. A sensor integrated into the frame assembly monitors the pressure of the delivered gas and adjusts the flow rate accordingly. The device is constructed with a lightweight yet durable material to reduce the overall weight of the device.
Novelty and Inventive Step
The new inventive concept introduces a stabilizing component, 3D printing, modular architecture, pressure monitoring, and lightweight materials, which are not present in the original patent. These innovations provide a significant improvement in stability, ease of use, and overall performance of the patient interface device.
Alternative Embodiments and Variations
Alternative embodiments of the inventive concept could include different types of stabilizing components, such as dampers or shock absorbers, or alternative 3D printing materials and techniques. Additionally, the modular architecture could be adapted for use in other medical devices, and the pressure monitoring system could be integrated with other sensors to provide a more comprehensive monitoring system.
Potential Commercial Applications and Market
The enhanced patient interface device has significant commercial potential in the medical device industry, particularly in the fields of respiratory care, anesthesia, and critical care. The device's improved stability, ease of use, and performance make it an attractive option for hospitals, clinics, and other healthcare providers.
