MUMBAI, India, Jan. 2 -- Intellectual Property India has published a patent application (202511103012 A) filed by Dit University, Dehradun, Uttarakhand, on Oct. 25, 2025, for 'a nebulizer system and a method for intranasal delivery of liquid drug formulations in laboratory animals.'
Inventor(s) include Anuj Uniyal; Giriraj T Kulkarni; Garima Varshney; Mandeep Kumar Arora; and Anglina Kisku.
The application for the patent was published on Dec. 12, under issue no. 50/2025.
According to the abstract released by the Intellectual Property India: "The present invention relates to a nebulizer system (100) for the intranasal delivery of liquid drug formulations in laboratory animals is disclosed. The system comprises a nebulizer unit (101) incorporating a vibrating mesh or ultrasonic element to generate aerosol particles in the 1-5 m range, and a drug reservoir (102) with a sealed capacity of 0.5-5 mL operatively coupled to the nebulizer. A nasal delivery interface (103), shaped as a contoured plastic nose-cone, is configured to fit over the snout of rodents and direct aerosolized drug into both nostrils while minimizing environmental dispersion. The animal is secured in an animal holding chamber (104) designed to allow normal respiration with minimal restraint. A flow control system (105) delivers regulated airflow between 0.5-2 L/min, facilitating precise aerosol transport from the nebulizer to the nasal interface. The entire system is housed in a compact, modular, and detachable housing unit (106) allowing for easy cleaning and sterilization. An electronic controller may be coupled to the flow control system to regulate dose timing and aerosol delivery rate. A corresponding method (200) of use enables consistent, reproducible, and non-invasive drug delivery without anesthesia, enhancing translational research applications in rodent models."
