Legal Citation
Summary of the Inventive Concept
The present inventive concept relates to a supraglottic airway device with enhanced features, including a reinforced breathing tube, integrated suction port, adjustable cuff pressure monitoring, detachable filter module, and securing adhesive, to improve patient safety, reduce complications, and enhance user experience.
Background and Problem Solved
The original supraglottic airway device, as described in the original patent, has inherent limitations, including the risk of puncture, inadequate suction capabilities, and lack of real-time cuff pressure monitoring. The present inventive concept addresses these limitations by introducing innovative solutions to improve the overall performance and safety of the device.
Detailed Description of the Inventive Concept
The enhanced supraglottic airway device comprises a breathing tube with a reinforced material at the cuff region, reducing the risk of puncture during use. The coupler assembly is equipped with an integrated suction port, enabling simultaneous suction and airflow without additional components. The device features an adjustable cuff pressure monitoring system, providing real-time feedback to medical professionals to ensure optimal cuff pressure. A detachable and reusable filter module allows for easy cleaning and replacement, reducing maintenance costs and environmental impact. Additionally, a securing adhesive is applied to the device to prevent dislodgement and ensure a secure fit.
Novelty and Inventive Step
The present inventive concept introduces several novel features that distinguish it from the original patent, including the reinforced breathing tube, integrated suction port, adjustable cuff pressure monitoring, detachable filter module, and securing adhesive. These features provide a significant improvement in patient safety, device performance, and user experience, thereby constituting an inventive step over the prior art.
Alternative Embodiments and Variations
Alternative embodiments of the inventive concept may include variations in the material used for the reinforced breathing tube, different designs for the integrated suction port, or alternative methods for securing the device to the patient. Additionally, the detachable filter module could be replaced with a disposable filter or a modular filter system, allowing for customization and flexibility.
Potential Commercial Applications and Market
The enhanced supraglottic airway device has significant commercial potential in the medical device industry, particularly in the fields of anesthesiology, emergency medicine, and critical care. The device's improved features and functionality make it an attractive solution for hospitals, clinics, and medical professionals seeking to enhance patient safety and reduce complications.
