Patent No. EP3756713 (titled "Atomization Device Having Dual Modules") was filed by Feellife Health on Mar 13, 2019. The application was issued on Aug 17, 2022.
A nebulization device comprises a host machine, a controller, a ventilator, a mask, and a three-way tube. The host machine includes a side cover, a liquid medicine bottle, a nebulization sheet, and a nozzle. A partition plate divides the nozzle into an upper nebulization chamber and a lower gas flow chamber. A gas flow detection structure, featuring an inverted trapezoidal plate and a gas chamber, extends into the three-way tube. A sensor, located in a slot within the trapezoidal plate, detects gas flow signals and transmits them via a first circuit board to the controller. The controller drives the host machine to eject nebulized medicine. The device supports a variable frequency mode for respiratory synchronization and a fixed frequency mode for continuous nebulization.

Patent oppositions filed by competitors challenge the validity of a granted patent. These oppositions are typically based on claims of prior art, lack of novelty, or non-obviousness. They are a key part of the process for determining a patent's strength and enforceability.
