MUMBAI, India, May 30 -- Intellectual Property India has published a patent application (202321076758 A) filed by Adwani, Lajwanti Lalwani; and Lalwani, Jyoti, Wardha, Maharashtra, on Nov. 9, 2023, for 'a portable airway clearance device.'
Inventor(s) include Adwani, Lajwanti Lalwani; and Lalwani, Jyoti.
The application for the patent was published on May 30, under issue no. 22/2025.
According to the abstract released by the Intellectual Property India: "The present invention is related to a portable airway clearance device designed to improve respiratory health by enhancing airway clearance and reducing secretion retention. The device consists of a mouthpiece (101) for exhalation, a valve (102) that regulates airflow and provides resistance to generate positive expiratory pressure (PEP), and a manometer (103) for real-time monitoring of pressure levels, allowing users to maintain customized PEP settings. An amplifier (104) enhances the pressure effect, while a water chamber (105) adds resistance and humidity to the exhaled air, improving comfort and efficacy. The tube (106) connects the components, ensuring smooth airflow and maintaining pressure throughout the device. This device is lightweight, affordable, and user-friendly, suitable for both clinical and home use, particularly for postoperative care and chronic respiratory conditions. By enabling personalized PEP adjustments, it aids in reducing the risk of reinfection, clearing airway secretions, and supporting lung health in individuals with respiratory difficulties."
