Breathing device for intra=oral use

摘要

The breathing device (10) consists of an intraoral breathing insert (11) with two air supply tubes (12,13) connected to it by connecting sections (16,17) in the side sections of the insert. The insert is made of plastics and has two main parts namely an upper jaw plate (18) and lower plate (19) which faces the lower part of the mouth. The upper jaw plate is formed so as to fit over the teeth and has a double concave shape. The lower plate has a similar shape in its middle but with less depth and a slightly bigger radius. Between the two plates is a hollow area (37) which widens slightly from front to back and also from side to side due to the concave shape. The hollow area ends in an outlet (14). Air is passed to the outlet from a compressor via the supply tubes.
