[Prior art] Anesthesia laryngeal mask (Laryngeal_Mask Construction) is a medical aid used when administering anesthetic gas to a patient. US Patent Publication No. 5,355,879 'is to disclose the structure of an anesthesia laryngeal mask' such as As shown in FIGS. 1 and 2, the laryngeal mask includes an air tube 10, an inflatable ring 20 connected to the air tube 10, and an inflatable tube 30 connected to the air ring 20. One end is the inlet end, and the other end is diagonally connected to the inflatable ring 20, and an inner hole corresponding to the inner ring of the inflatable ring 20 is formed at the joint with a through hole 11 corresponding to the front of the through hole 11 of the air duct 10. 15 The end wall is shaped as a pointed arc-shaped body 12 to facilitate the laryngeal mask to be inserted into the patient's mouth from there. The inflatable ring 20 is an oval-shaped inflatable balloon. In addition, the inflatable tube 30 is The inflatable ring 20 is inflated and evacuated by pulling the inflatable cylinder (not shown) to control the inflation and contraction of the inflatable ring 20. When the above-mentioned laryngeal mask is used, the un-inflated laryngeal mask is inserted into the throat from the patient's mouth through 20, and the patient's trachea is corresponding to the vent hole 11, and then inflated through the external inflation tube 30, so that The inflatable ring 20 expands against the entire larynx, so that there is no gap between the patient's larynx and the laryngeal mask, and the trachea must be completely aligned with the vent hole 11, so that anesthetic gas is sent from the inlet end of the airway 10 It will enter the trachea directly and will not escape into other parts 4 M253359. 5 10 However, although the above-mentioned embodiment can achieve the expected function, the laryngeal mask is placed before the patient is anesthetized, and the laryngeal inflatable ring 20 is made of a soft flexible material, so it can only rely on &Amp; 10 pointed arc-shaped body 12 at the front end guides the plug person, but the pointed arc-shaped body 12 2 the front end of the inflatable ring 20 is too far 'does not have much guiding effect, so the laryngeal mask is in the plug user In the throat, there will be problems such as difficulty in aligning the penetration holes U, and tube parts, which makes installation difficult. Second, medical personnel often stop at the plug = laryngeal mask because of the poor installation of the 2G inflatable ring, and Being used by the user; ^ against the local inflatable ring 20, which can not be filled with gas locally, and the inflatable ring 20 cannot be fully expanded. In contrast, the inflatable ring buckle is not fully expanded, which will cause the trachea and the vent hole. u can't be all aligned ', = there is a gap between the two, so when the anaesthetic gas is filled, the danger that the anaesthetic gas 15 will escape to various parts of the human body, so this type of laryngeal mask is still in the installation. There is a major shortcoming that needs to be improved. [New content] Therefore, the object of the present invention is to provide a laryngeal mask for anesthesia with a guiding function, which can be easily accommodated in a user's throat, and can improve the lack of traditional manufacturing methods. Therefore, the laryngeal mask for anesthesia with a guiding function of the present invention includes an inflatable ring, a guide piece, an inflatable device, and an air tube. The inflatable ring is made of a flexible material and can be used.
