However, when the oxygen inhaler is inhaling oxygen, there is still a certain size gap between the nostril tube and the nostril, which may cause some of the oxygen released by the nostril tube to leak, resulting in easy waste of a large amount of oxygen, and the oxygen inhalation effect of the oxygen inhaler is not good. Content of the Utility Model

[0005] The purpose of the utility model is to provide a mask-type nasal oxygen tube, which has the advantages of convenient installation and can reduce the waste of oxygen during oxygen inhalation, and solves the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A face mask type nasal oxygen tube includes two oxygen delivery tubes. One end of the two oxygen delivery tubes close to each other is connected to a nostril tube, and both oxygen delivery tubes are connected to the nostril tube and communicate with it.

[0023] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1-6 , the present utility model provides a technical solution: a mask-type nasal oxygen tube, including two oxygen delivery tubes 1. One ends of the two oxygen delivery tubes 1 close to each other are connected with a nostril tube 2, and both of the two oxygen delivery tubes 1 are communicated with the nostril tube 2. One ends of the two oxygen delivery tubes 1 far from the nostril tube 2 are both connected with an oxygen source connector 7. A restricting mechanism 3 is arranged on the outer side of the nostril tube 2, and the restricting mechanism 3 is also arranged on the outer side of the oxygen delivery tube 1. The restricting mechanism 3 is used for reducing oxygen leakage. The two oxygen delivery tubes 1 can effectively install and connect the nostril tube 2. At the same time, the oxygen source connector 7 is used to connect with an external oxygen protection device, so that oxygen can smoothly flow into the interior of the oxygen delivery tube 1 through the oxygen source connector 7 and flow into the nostril tube 2 through the oxygen delivery tube 1, realizing the inhalation of oxygen by the oxygen absorber. The setting of the restricting mechanism 3 can effectively reduce oxygen waste, so that the oxygen absorber can inhale more oxygen when inhaling oxygen.

[0025] Please refer to Figures 1-6:The limiting mechanism 3 includes an upper mask 31 and a lower mask 32 connected to the outer side of the oxygen delivery tube 1. A connecting block 33 is connected to the outer side of the upper mask 31. One side of the lower mask 32 is connected to a fixing plate 34. A one-way screw 35 is connected to the upper side of the fixing plate 34. The one-way screw 35 is threadedly connected to the inner side of the connecting block 33. The outer side of the upper mask 31 is connected to a first elastic cord 361 and a second elastic cord 362. A sub-magic tape 363 is connected to the inner side of the first elastic cord 361. A first mother-magic tape 364 is connected to the outer side of the second elastic cord 362. And the first mother-magic tape 364 is bonded to the sub-magic tape 363. The upper mask 31 and the lower mask 32 can effectively limit the oxygen released by the nostril tube 2 and not inhaled, so that the oxygen is not easily floating into the air smoothly. And when the oxygen absorber takes oxygen next time, the oxygen limited by the upper mask 31 and the lower mask 32 can be adsorbed together, thus reducing the waste of oxygen. The upper mask 31 can connect the connecting block 33. The lower mask 32 can connect the one-way screw 35 through the fixing plate 34. The one-way screw 35 can make the upper mask 31 and the lower mask 32 be connected together smoothly through the threaded connection between itself and the connecting block 33. At the same time, the upper mask 31 can also effectively install and fix the first elastic cord 361 and the second elastic cord 362. At the same time, the first elastic cord 361 and the second elastic cord 362 are worn on the back of the head of the oxygen absorber. After the sub-magic tape 363 connected to one side of the first elastic cord 361 is bonded to the first mother-magic tape 364 connected to one side of the second elastic cord 362, the upper mask 31 and the lower mask 32 can be effectively worn on the head of the oxygen absorber, thus increasing the oxygen absorption amount.

[0026] Please refer to Figure 4 :A slot 81 is opened on the lower side of the upper mask 31. An insertion block 82 is connected to the upper side of the lower mask 32. And the insertion block 82 is connected inside the slot 81. The lower mask 32 can effectively install and fix the insertion block 82. After the insertion block 82 is connected to the upper mask 31 through the slot 81, it can increase the stability when the upper mask 31 and the lower mask 32 are connected, and play a certain sealing role at the connection between the upper mask 31 and the lower mask 32, thus reducing the possibility of oxygen leakage through the connection between the upper mask 31 and the lower mask 32.

[0027] Please refer to Figure 6: One side of the second elastic cord 362 is connected to the auxiliary elastic cord 41, and the outside of the auxiliary elastic cord 41 is connected to the second female Velcro 42. The second female Velcro 42 and the child Velcro 363 are bonded to each other. The second elastic cord 362 can install and fix the second female Velcro 42 through the auxiliary elastic cord 41. After the second female Velcro 42 is bonded to the child Velcro 363, it can increase the stability of the child Velcro 363 and the first female Velcro 364 when connected, thereby further increasing the stability of the second elastic cord 362 and the first elastic cord 361 when worn on the head of the oxygen inhaler.

[0028] It should be noted that: the outer side of the nasal tube 2 is bonded to the oxygen supply tube 1, the inner side of the oxygen source connector 7 is bonded to the oxygen supply tube 1, the outer side of the upper mask 31 is screwed to the connecting block 33, the outer side of the lower mask 32 is screwed to the fixing plate 34, the lower end of the one-way screw 35 is slidably sleeved between the fixing plate 34, the outer side of the one-way screw 35 is threadedly connected to the connecting block 33, one side of the first elastic cord 361 is bonded to the upper mask 31, the inner side of the first elastic cord 361 is bonded to the connecting block 33, and one side of the second elastic cord 362 is bonded to the upper mask 31. The covers 31 are also bonded together, the outer side of the second elastic cord 362 is bonded to the first female Velcro 364, and the outer side of the first female Velcro 364 is connected to the child Velcro 363 by bonding. The lower side of the plug-in block 82 is screwed to the lower cover 32, and the outer side of the plug-in block 82 is movably connected to the upper cover 31 through the slot 81. One side of the auxiliary elastic cord 41 is bonded to the second elastic cord 362, one side of the second female Velcro 42 is bonded to the auxiliary elastic cord 41, and the outer side of the second female Velcro 42 is bonded to the child Velcro 363.

[0029] See also Figures 2-4 : A second sealing rubber layer 9 is connected to the inner side of the upper mask 31, and a first sealing rubber layer 6 is connected to one side of the upper mask 31 and the lower mask 32. The provision of the second sealing rubber layer 9 can further enhance the sealing performance of the connection between the upper mask 31 and the lower mask 32, thereby further reducing oxygen leakage. At the same time, the provision of the first sealing rubber layer 6 can reduce the gap between the upper mask 31, the lower mask 32 and the face of the oxygen inhaler, thereby making it difficult for oxygen to leak through the gap between the upper mask 31, the lower mask 32 and the face of the oxygen inhaler.

[0030] See also Figure 1 and Figure 5:The upper end of the unidirectional screw 35 is connected with an extension rod 11, and the diameter of the extension rod 11 is smaller than that of the unidirectional screw 35. An air outlet hole 5 is provided on the upper side of the upper mask 31, and a plurality of air outlet holes 5 are provided. The setting of the extension rod 11 facilitates the rotation of the unidirectional screw 35 by the staff. Since the diameter of the extension rod 11 is smaller than that of the unidirectional screw 35, when the staff connects the connecting block 33 through the unidirectional screw 35, the extension rod 11 is not likely to hinder the connection between the connecting block 33 and the unidirectional screw 35. At the same time, the provision of the air outlet hole 5 enables the gas exhaled by the oxygen absorber to smoothly pass through the air outlet hole 5 and be discharged to the outside of the upper mask 31 and the lower mask 32, and it is not easy to have the situation where exhalation cannot be carried out smoothly. At the same time, because the density of oxygen is greater than that of air, the air outlet hole 5 is provided on the upper side of the upper mask 31, so that oxygen can reduce the situation of oxygen flowing out through the air outlet hole 5 as much as possible.

[0031] Please refer to Figure 1 and Figure 2 : Third sealing rubber layers 10 are connected to the outer sides of the two oxygen delivery tubes 1, and the two third sealing rubber layers 10 are both arranged on the outer side of the upper mask 31. Through the setting of the third sealing rubber layer 10, the sealing performance between the upper mask 31 and the lower mask 32 and the oxygen delivery tube 1 can be increased, thereby further reducing the gap between the oxygen delivery tube 1 and the upper mask 31 and the lower mask 32, and further improving the sealing performance of the upper mask 31 and the lower mask 32 during use.

[0032] It should be noted that: One side of the second sealing rubber layer 9 is bonded to the upper mask 31, one sides of the two first sealing rubber layers 6 are respectively bonded to the upper mask 31 and the lower mask 32, the lower end of the extension rod 11 is screwed to the upper end of the unidirectional screw 35, and the inner sides of the two third sealing rubber layers 10 are bonded to the oxygen delivery tube 1.

[0033] Working principle: When the utility model is in use, the staff can place the lower mask 32 outside the oxygen delivery tube 1, and connect the connecting block 33 on one side of the upper mask 31 to the outside of the one-way screw 35. When connecting, the one-way screw 35 needs to be rotated. When the one-way screw 35 rotates, it can smoothly move the upper mask 31 downward through the threaded connection between itself and the connecting block 33. When the upper mask 31 moves a certain distance, it can contact and connect with the lower mask 32. Then, the staff can place the nostril tube 2 at the nose of the oxygen inhaler, and wind the oxygen delivery tube 1 around the outside of the oxygen inhaler's ear. At this time, the upper mask 31 and the lower mask 32 will also be worn at the mouth and nose of the patient. Then, the first elastic cord 361 and the second elastic cord 362 can be worn at the back of the oxygen inhaler's head, and the first elastic cord 361 and the second elastic cord 362 are connected through the adhesion between the sub-magic tape 363 and the first mother magic tape 364. When the first elastic cord 361 and the second elastic cord 362 are connected, the use and wearing of the upper mask 31 and the lower mask 32 can be realized, thereby reducing the waste of oxygen when it is inhaled.
