Abstract: Disclosed is a portable first-aid anti-asphyxiation device that automatically takes foreign matter from a respiratory airway, relating to medical care supplies. It generates suction force automatically by pressing the trigger button. The device is operated easily. The obstructions in the airway can be eliminated quickly. Since the suction force is controlled by the spring inside the device and the stops on the piston rod, the structure of the device is simple. The device generates the same force each time. The suction force may not be variable due to manual operation. Compared to the devices on the market that requires a person to operate with both hands, the device of the present disclosure is safer, can be operated easily, and can generate stable results.

Abstract: The present invention relates to the technical field of an automatic detection trigger device, and discloses an automatic detection trigger device for a quantitative compressed administration aerosol.
