Clear- One-Way: Specially designed valve that allows air to move in only one direction. When pressure is applied, the air escapes from the sides and is not directed into the lungs, preventing the risk of pushing the object deeper.
- Piston: The device has a cylindrical body and a plunger, functioning like a large medical syringe. By placing the mouthpiece/mask and pulling the plunger sharply, a strong suction vacuum is created to clear the airway.
- Manual Vacuum Pump: The mechanism consists of a compressible chamber resembling an accordion. The user places the mask on the face, presses the bellows downward to expel the air, and then pulls the handle sharply upward.
