beißfeste and positionable breathing mask

摘要

A positioning and bit-proof throat mask retainer is a flexibly and slightly hard tube capable of being adhered to an upper side of a throat mask respiratory siphon. A lower side of the retainer is matched with an arc shape of the respiratory siphon and has a hollow cambered structure and an upper side of the retainer is suitable for the upper side of the oral cavity. A front end of the retainer is bent upwards to be formed as a resisting portion for resisting against an upper jaw of the patient along the cambered shape of the upper jaw. By the supporting of the upper jaw, the retainer is fixed to the mouth of a patient, thereby, having a function of guiding and positioning the respiratory siphon.
