Disclosed herein are embodiments of an electric suction device for emergency airway obstruction removal and anti-choking, relating to the field of emergency rescue technology. One embodiment comprises a face mask, with an electric suction mechanism set on the surface of the face mask. The electric suction mechanism includes an oral support that is movably installed inside the face mask. The face mask is pressed tightly against the face and adjusted to form a sealed space. Activating the electric suction mechanism switch triggers the control circuit board to power the one-way suction module via the battery. This controls the one-way suction module to extract air, creating negative pressure in the sealed space.Consequently, the obstructing object is suctioned out of the airway due to continuous negative pressure. When the patient is unconscious or unable to cooperate, the oral support can be inserted into the patient's mouth to ensure that the patient's mouth is open and the device can be used. This device is easy to operate, safe and stable. The suction of this device can be controlled and there are different types of masks that can be configured to meet different people. It can be used independently by the patient without third-party assistance, or by a rescuer when the patient is unable to perform self-rescue.
