What sets Willnice apart is their patented double-valve system. This innovative system offers a significant advancement over traditional choking devices by incorporating two valves that function in harmony to ensure optimal safety and efficient obstruction removal. 

When pressure is applied, the first valve located in the center closes, while simultaneously the second valves on both sides open, allowing for controlled expulsion of air. This ingenious mechanism prevents the unwanted entry of air into the airway and effectively halts any obstruction from being pushed further, thus reducing the risk of potential harm.

The intelligent deployment of the valves, with the first valve opening and the second valve closing when the device is pulled, generates a robust negative pressure that enhances suction power, allowing for effective removal of foreign objects lodged in the airway. This comprehensive approach ensures maximum safety and efficient obstruction clearance for patients in need.

Unlike other choking devices, this central cavity plays a crucial role in maintaining safety during the obstruction removal process. In other choking designs, the center of the device is hollow. There is a possibility of air being forcefully pushed into the airway, which can be unsafe and potentially exacerbate the situation by pushing the obstructions deeper. However, Willnice’s double-valve design eliminates this risk by preventing any air from entering the airway, ensuring that the obstruction remains isolated and does not pose a further threat.
