- Facilitates speech for laryngectomy patients: Enhances the quality of life by enabling clearer, more natural speech for individuals who have undergone a laryngectomy.
- Accessible and Safe: Provides a reliable, biocompatible solution for voice restoration, improving patient outcomes.
- Convenient and Cost-Effective: The device is affordable, has an increased lifespan, and can be easily cleaned and disinfected by the patient at home.
- Comprehensive Tool Set: The invention includes specialized insertion, removal, and combined insertion-removal tools, all crafted from biocompatible stainless steel, for precise handling and placement of the device.
- Adjustable Valve Seat: The valve seat at the esophagus side of the inner cylinder is inclined at specific angles (preferably 5-20°), ensuring optimal function and sealing of the flap valve.
- Innovative Dual-Cylinder Design with Integrated Flap Valve: The device features a hollow inner cylinder that moves within an outer cylinder for secure placement, and a unique circular flap valve that controls air passage.
- Durable and Visible Materials: Made from flexible, medical-grade polymers, the device includes radiopaque properties for easy visibility and monitoring under imaging techniques.
