To make it possible to easily attach and detach the above implement with one hand and to prevent the contact with the nostrils by either of right and left cannula front ends and the contact of the cannula front ends with the nostrils at the time of attaching and detaching by forming a cannula of one tubular form and fixing the cannula to either of the right or left side of a spectacle frame.
This spectacle type oxygen inhalation implement is constituted by irreversibly fixing one piece of the cannula, which is connected at one end to an oxygen cylinder to an oxygen supply source of an adsorption type oxygen thickener, etc., and is bent at the other end to a U shape, to either of the right or left bow portions of the spectacle frame or lens frame and supplying gaseous oxygen to the one nostril from the lower side of nose wings of the spectacles. The method for fixing the cannula is preferably a method of fixing an annular portion to the inner side of the frame and passing the cannula into the ring, thereby mounting the cannula. The cannula is required to be exchanged by long-term use. Also, the mounting part is disposed in the bow portion and the upper part of the spectacle frame as well as the lower part of the nose wing portions on the inner side of the spectacle frame.
