An artificial airway device (1) to facilitate pulmonary ventilation of a patient, comprising at least one airway tube (2) and a mask (39) carried at one end of at least one airway tube (2 ), the mask having an inflatable peripheral formation (46) capable of adapting to, and easily adjusting within, the real and potential space behind the patient's larynx to form a seal around the circumference of the laryngeal inlet, surrounding the peripheral formation (46) a hollow interior space or lumen of the mask (39) and the at least one airway tube (2) opening inside the lumen of the mask (39), in which the mask (39) provides a space for the drainage of gastric matter leaving the esophagus, in which the space is an internal volume of the mask (39) within the body of the mask (39) that forms a generally truncated conical channel within the body of the mask , which has a circular inlet (50) at the distal end of the mask and an outlet (56) at the rear end of the mask, outlet that has an area of cross section greater than the entry in the plane perpendicular to the longitudinal axis of the mask, to effect a significant increase in fluid pressure that arises from the esophageal sphincter while still providing an inflatable mask shape that maintains the seal around the circumference of the laryngeal inlet.Un dispositivo de vía respiratoria artificial (1) para facilitar la ventilación pulmonar de un paciente, que comprende al menos un tubo de vía respiratoria (2) y una máscara (39) portados en un extremo de al menos un tubo de vía respiratoria (2), teniendo la máscara una formación periférica hinchable (46) capaz de adaptarse a, y de ajustarse fácilmente dentro de, el espacio real y potencial detrás de la laringe del paciente para formar un sello alrededor de la circunferencia de la entrada laríngea, rodeando la formación periférica (46) un espacio interior hueco o lumen de la máscara (39) y abriéndose el al menos un tubo de vía respiratoria (2) al interior del lumen de la máscara
