Title:
METHOD FOR ESTABLISHING ORAL RESPIRATORY AIRFLOW PASSAGE, AND SUPPORT THEREOF
Document Type and Number:
WIPO Patent Application WO/2022/199197
Kind Code:
A1
Abstract:
Provided are a method for establishing an oral respiratory airflow passage for sleep-disordered breathing, and a support thereof. All oral respiration auxiliary devices currently available in the market use a method for forcing the oral cavity proper to be in a semi-open state, which has defects in terms of comfort, reliability, etc. The technical solution of the present application provides a U-shaped support made of a soft elastic material, wherein the two sides of the U-shape are symmetrical left and right supporting bodies; the bottom end of the U-shape is a cavity which is disposed between the lips and includes respiratory airflow inlet/outlet ports; a left end and a right end of the cavity are respectively connected to front ends of the left and right supporting bodies; and the left and right supporting bodies are respectively disposed in left and right oral vestibules, so as to establish an oral respiratory airflow passage formed of a respiratory airflow passage 1, which starts from the gap between the maxillary tubercle and the retromolar area and passes through the pterygomandibular space and along the dentition and the periphery of the gum to reach the cavity (1), and a respiratory airflow passage 2, which is composed of small spaces between chewing surfaces of the maxillary dentition and the mandibular dentition and connects the oral cavity proper and the oral vestibule.
