Referring to FIGS. 8 and 9, when the user wears the respiratory mask 2 having the guide member 40 and must be provided with the catheter 21 for feeding, the external catheter 21 can be inserted through the outer end of the through hole 521 of the mounting pad 52 of the plug body 5. The insertion hole 511 of the elastic holding piece 51 is inserted into the nose of the user by the inner end of the through hole 521 of the mounting pad 52. The hole diameter of the insertion hole 511 of the elastic holding piece 51 is slightly smaller than the outer diameter of the catheter 21. Therefore, when the catheter 21 is inserted into the insertion hole 511, the elastic elastic holding piece 51 can elastically hold the catheter 21, thereby causing the positioning so that the catheter 21 does not easily come loose or slide. It should be noted that the size of the aperture of the insertion hole 511 can be changed according to the outer diameter of the catheter 21, and the design of the insertion hole 511 is slightly smaller than the outer diameter of the catheter 21, so that the catheter 21 is passed through. When the hole 511 is inserted, it can be clamped by the elastic holding piece 51. Moreover, when the breathing mask 2 is actually used, other inner tubes, such as a stomach tube, a twitch tube, an endoscope, etc., may be inserted, so that the breathing is performed. After the catheter 21 is inserted into the insertion hole 511, the mask 2 can be engaged with the second fracture line 523 by the first fracture line 512, so that the insertion hole 511 is expanded to allow other inner tubes to be inserted, and the elasticity is utilized. The elastic restoring force of the holding piece 51 and the mounting pad 52 causes the elastic holding piece 51 to be tightly connected to the catheter 21 and the other inner tube without slipping or air leakage.

Referring to FIG. 10, if the outer diameter of the conduit 21' is large, for example, the outer diameter of the conduit 21' approaches the aperture of the through hole 521 of the mounting pad 52, and the first break occurs when the conduit 21' is bored through the through hole 521 and the insertion hole 511. The wire 512 will be fully extended and the bottom end of the second breaking line 523 will be slightly expanded, and the catheter 21' will press the elastic clamping piece 51 inwardly to cause the elastic clamping piece 51 to be deformed. At this time, the catheter 21' It can still be held by the elastic holding piece 51. At the same time, by the design that the thickness of the mounting pad 52 is larger than the thickness of the elastic holding piece 51, a relatively stable supporting force can be provided, so that the catheter 21' can be stably penetrated in the through hole 521 and held by the elastic holding piece 51.

In addition, by the arrangement of the rib 527 and the groove 528, when the catheter 21' having a larger outer diameter is inserted into the through hole 521, the force of the rib 527 and the groove 528 is overcome to obtain the first and second sections 525. The bottom of the 526 is slightly separated to avoid misalignment between the first and second sections 525 and 526 when the catheter 21' is inserted, thereby causing the elastic clamping piece 51 to be unable to firmly hold the catheter 21'.

Referring to FIG. 4, FIG. 11 and FIG. 12, the sealing plug 6 includes a connecting piece 61 connected to the plug body 5 and a sealing hole disposed at the end of the connecting piece 61 for inserting through the insertion hole 511 to close the insertion hole 511. Section 62. The sealing portion 62 includes a shielding piece 621 which is connected to the shielding piece 511 and has a circular shape for shielding the insertion hole 511.

The outer diameter of the shielding piece 621 and the outer diameter of the protruding post 622 are larger than the opening diameter of the insertion hole 511. When the user does not need to use the catheter 21, 21', the pull tab 63 at the bottom end of the shielding piece 621 can be pulled in the direction indicated by the arrow I to bend the connecting piece 61 and insert the fastening block 623 of the sealing portion 62 through the insertion. The hole 511 is configured to fasten the fastening block 623 to the inner side of the elastic clamping piece 51. Since the outer diameter of the protruding post 622 and the outer diameter of the shielding piece 621 are larger than the opening diameter of the insertion hole 511, the protruding post 622 is inserted through the insertion hole. When the 511 is held by the elastic clamping piece 51, the shielding piece 621 abuts against the outer side of the elastic clamping piece 51 and shields the insertion hole 511, so that the sealing portion 62 can seal the insertion hole 511 to avoid the cover body. The gas in 20 is generated by air leakage through the insertion hole 511. In addition, when the sealing portion 62 is to be detached from the insertion hole 511, the pull tab 63 is reversely pulled along the arrow I, so that the fastening block 623 spreads the insertion hole 511 away from the insertion hole 511, and then the sealing portion 62 is completed.
