When the laryngeal mask is implanted in the patient's throat, the breathing chamber 210 communicates with the patient's airway through the breathing orifice 220, and breathing gas enters the breathing chamber 210 through the breathing chamber 110 and then enters the patient's airway through the breathing orifice 220, thereby ensuring that the patient can breathe normally when the laryngeal mask is implanted in the patient's throat.
According to the technical scheme, the breathing cavity 110 for ventilation of breathing gas is arranged on the tube body 100, the breathing cavity 210 communicated with the breathing cavity 110 is arranged on the mask body 200, the breathing port 220 is arranged on the mask body 200, when the laryngeal mask is implanted into the throat of a patient, the breathing cavity 210 is communicated with the respiratory tract of the patient by the aid of the breathing port 220, the guide ridge 260 extending along the length direction of the laryngeal mask is arranged on the mask body 200, the guide ridge 260 protrudes from the surface of the mask body 200, so that the guide ridge 260 protruding from the surface of the mask body 200 is mutually extruded with laryngeal tissues in the process of implanting the laryngeal mask into the throat of the patient, the extending direction of the guide structure is identical with the direction of the laryngeal tissues extruded and recessed, and the problem that the implantation direction is easy to deviate from the initial implantation direction in the laryngeal mask implantation process, and the implantation direction needs to be adjusted in time in the implantation process is solved, so that the laryngeal mask is inconvenient in the implantation process is solved.
It will be appreciated that in the above embodiments, the mask body 200 is connected to the tube body 100, and the direction in which the mask body 200 is connected to the tube body 100 is the length direction of the laryngeal mask.

In one embodiment, the laryngeal mask has opposite anterior and posterior sides, the breathing orifice 220 is located on the anterior side and the guide ridge 260 is located on the posterior side. When the laryngeal mask is implanted in the throat of the patient, the breathing opening 220 at the front side is communicated with the respiratory tract of the patient, so that in order to ensure the sealing effect between the laryngeal mask and the throat of the patient, the front side needs to be in sealing abutting joint with the tissue of the throat of the patient as much as possible, the guide ridge 260 is arranged at the rear side in the embodiment, the guide ridge 260 is utilized to play a guiding role in the implantation process, and meanwhile, the guide ridge 260 is prevented from influencing the sealing effect between the mask body 200 and the throat of the patient, so that the front side of the mask body 200 can be better sealed with the throat of the patient after the laryngeal mask is implanted, and the respiratory gas can be ensured to be smoothly acquired by the patient.
In one embodiment, the guide ridge 260 is provided at the junction of the tube 100 and the housing 200. Because the structure of the mask body 200 is different from that of the tube body 100, the joint between the mask body 200 and the tube body 100 is easier to squeeze and deform during the laryngeal mask implanting process, so that the implantation direction is easier to deviate during the implanting process, and the guide ridge 260 is arranged at the joint between the tube body 100 and the mask body 200, so that the guide effect can be better achieved during the implanting process. In addition, the guide ridge 260 also plays a role in enhancing the structural strength of the joint of the mask body 200 and the tube body 100, so that the joint of the mask body 200 and the tube body 100 is not easy to bend in the laryngeal mask implantation process, and the channel blockage at the joint of the mask body 200 and the tube body 100 caused by bending is avoided, so that the respiratory tract 110 and the respiratory cavity 210 are kept in communication.
