At present, in clinical medical treatment, surgical anesthesia or other requirements for introducing medical gas into a human body frequently exist, and the traditional common mode is to use an air conduit and an endotracheal tube for intubation, so that the smoothness of a respiratory tract can be maintained in the process of anesthesia or introducing the medical gas into the human body; however, the intubation operation and procedure described above cause serious discomfort to many patients, and in order to relieve the pain of the patients, another laryngeal mask device capable of replacing the endotracheal tube is gradually and widely used in the occasions where the requirement for maintaining the airway is needed.

In taiwan patent publication No. M340819, a structure of a self-organizing throat mask set is disclosed, which mainly comprises: an air supply hood unit including a main seat pipe, a support pad, a positioning piece, and a cover film, which can be assembled and disassembled; the main seat tube comprises a tube wall surrounding an axis and defining a through hole, a limiting sheet extending outwards from the periphery of one end of the tube wall in the radial direction, and an outward expanding body located above the limiting sheet and extending outwards from the outer peripheral surface of the tube wall; the supporting pad is removably sleeved between the outward expansion body of the main seat tube and the limiting sheet, and comprises a top surface facing the outward expansion body, a bottom surface facing the limiting sheet and a positioning hole extending from the top surface to penetrate through the bottom surface and sleeved between the limiting sheet and the outward expansion body, wherein the top surface and the bottom surface are reversely arranged; the positioning piece is attached to the bottom surface of the supporting pad and comprises a body part and an attaching part, wherein the body part is arranged corresponding to the supporting pad, the attaching part is arranged along the periphery of the top surface of the body part and is used for being combined with the supporting pad, and the body part is provided with a first vent hole and a second vent hole which are arranged at intervals and penetrate through the through hole of the main seat pipe; the mantle is covered outside the external expanding body and the limiting sheet of the main seat pipe, the supporting pad and the positioning sheet, and is provided with a mantle hole for the pipe wall of the main seat pipe to be closely sleeved and an opening which is separated from the mantle hole and is arranged corresponding to the first vent hole and the second vent hole of the positioning sheet; and an auxiliary member for inserting the cover film of the air supply mask unit to assist the air supply mask unit to go further toward the throat of the patient.

In the above structure, because the supporting pad is directly covered by the covering film, the covering film is supported by the supporting pad and keeps the expansion shape normally, when in use, the covering film is stretched into the throat in a fully expanded state, although the supporting pad is squeezed to generate elastic deformation in the process of stretching into the throat, the patient still can generate extreme discomfort.

In addition, taiwan patent publication No. M567115 discloses a throat mask, which comprises: the mask body is provided with a bag body and a supporting body, wherein the top of the supporting body is provided with a groove, and the bag body is correspondingly arranged on the groove; and a tube part having a vent tube and a filling tube connected with the bag body, wherein one end of the tube part is connected with the support body, the connection part has an opening connected with one end of the vent tube, the filling tube can inject external filler (liquid or gas) into the bag body to make the bag body fully expand.

After the filling material (liquid or gas) is injected into the bag body from the filling pipe body, the bag body can generate expansion slightly larger than the natural state due to the pushing force of the filling material from inside to outside so as to achieve the effects of being more attached to the inner wall of the throat to seal the esophagus and maintain the smoothness of the respiratory tract; however, since the expansion of the capsule cannot be directly observed when the capsule is inserted into the throat, the disadvantages of insufficient injected filler (too soft capsule, poor sealing effect) or excessive injected filler (too hard capsule, causing extreme discomfort to the patient) are often encountered.
