A laryngeal mask for covering an opening of the trachea and touching an opening of the esophagus of a patient is disclosed. The laryngeal mask has a tube and a mask portion, wherein the tube has a first end. The mask portion has an upper surface, a front end, and an esophageal blocking portion, wherein the upper surface connects to the first end； the esophageal blocking portion situates at the front end. When the laryngeal mask is being placed into the patient’s oral cavity, the esophageal blocking portion is moving along both sides of the esophagus and blocking the opening of the esophagus such that the opening of the trachea can be properly covered by the laryngeal mask.一種喉頭罩用以罩住病患之氣管開口，且與病患之食道開口接觸，喉頭罩包括管體以及罩體，其中管體包括第一端。罩體包括上頂面、前端以及食道封阻部，其中上頂面與管體之第一端結合，食道封阻部係位於前端，藉由上述結構，當喉頭罩進入病患口中，食道封阻部會沿著氣管兩側進入病患之食道開口，並封阻食道開口，而使喉頭罩適當地罩住氣管開口。
