The supply of oxygen from the supply device 31 may be performed according to the following procedure.
[0022]
First, the length of the head mounting band 9 of the cannula holder 1 shown in FIGS. 1 to 4 is adjusted according to the length of the outer circumference of the head 32b of the cannula wearer 32 and the like. In this length adjustment, first, the male hook-and-loop fastener 7 of the connecting strip 4 shown in FIGS. 1 and 3 is detached from the female hook-and-loop fastener 8. Then, the portion of the connecting band portion 4 inserted into the slit 6 of the right band-shaped main body portion 3 is changed by appropriately shifting in the longitudinal direction, and then the male surface fastener 7 is replaced with the female surface fastener. 8 again.
[0023]
Next, a head mounting band 9 composed of a pair of left and right band-shaped main bodies 2 and 3 and a connecting band 4 is mounted on the head 32 b of the cannula wearer 32. In this case, first, as shown in FIG. 6A, the pair of left and right band-shaped main bodies 2 and 3 is hooked on the left and right ears 32c of the cannula wearer 32 like a string of glasses. In other words, the respective ear hooks 2a, 3a of the pair of band-shaped main bodies 2, 3 are partially wound or abutted, respectively, substantially along the bases of the left and right ears 32c. The ear hooks 2a and 3a have a position holding function such as preventing the head mounting band 9 from rotating around the head 32b of the cannula wearer 32. Then, as shown in FIG. 6 (B), the front end portion of the left band-shaped main body portion 2 is applied to the forehead, and then the front end portion of the right band-shaped main body portion 3 is applied thereto. Thus, the female hook-and-loop fastener 12 is connected to the male hook-and-loop fastener 11. If necessary, the position of the tube locking member 14 is adjusted so that the tube locking member 14 is located substantially at the center of the forehead in the left-right direction. This adjustment may be performed by removing the female hook-and-loop fastener 15 from the male hook-and-loop fastener 13, adjusting the position of the tube locking member 14, and then reconnecting them.
[0024]
Next, the cannula wearer 32 wears the nostril cannula 21 shown in FIG. In this case, the connector 29 is connected to an oxygen supply device 31 as an oxygen supply source shown in FIG. 7 as generally known in the related art. Further, as shown in FIG. 6C, a pair of left and right prong portions 22d and 22e of the cannula main body 22 are inserted into left and right nostrils 35a and 35b of the cannula wearer 32, respectively. Further, the tube 16 is elastically gripped and locked by the hook-shaped locking portion 14b of the tube locking member 14 of the cannula holder 1. Further, the ring 33 is moved up and down so that the outer periphery of the opening 34 substantially surrounds the outer periphery of the nose 32a. In this case, the ring 33 can be positioned near the upper end of the nose 32a or substantially at the center of the eyes when viewed from the front. Note that these procedures may be performed in any order. Then, if oxygen is supplied from the oxygen supply device 31 after the preparation as described above is completed, the cannula wearer 32 can use the nostril cannula 21 in the same manner as in the case of a conventionally generally known nostril cannula device. The supply of oxygen can be received through.
