[0013] Furthermore, the ear strap assembly includes:

[0014] An elastic ear loop having a receiving cavity, wherein the two ends of the elastic ear loop are respectively connected to the airbag ring and the airbag pad; and,

[0015] A telescopic tube is provided inside the receiving cavity, with one end of the telescopic tube connected to the airbag ring and the other end connected to the airbag cushion.

[0016] Furthermore, the sealing disc has a through hole in the middle, and the sealing assembly is a rotary sealing assembly, which includes:

[0017] The movable column has its outer wall threadedly connected to the inner wall of the through hole; and,

[0018] A sealing plate is fixedly connected to one end of the movable column. The sealing plate corresponds to the exhaust hole and can abut against the sealing disc.

[0019] Furthermore, the airbag ring is connected to a fixing tube, which is threadedly connected to the mounting tube.

[0020] Furthermore, the sealing disc has a through hole in the middle, and the sealing assembly is a press-to-seal assembly, which includes:

[0041] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0042] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0043] Please see Figures 1 to 8 This application discloses a mask-type oxygen inhalation device for children, comprising:

[0044] Oxygen mask assembly, including inhalation mask 1;

[0045] An airbag ring 2 is disposed at the periphery of the inhalation mask 1;

[0046] The ear loop assembly is connected to the airbag ring 2, and the ear loop assembly is elastically extendable; and...

[0047] Airbag cushion 4 is connected to the ear strap assembly;

[0048] The mounting tube 8 is connected at one end to the airbag ring 2, and a one-way valve 10 is provided inside the mounting tube 8;

[0049] An exhaust assembly is provided in the portion of the mounting pipe 8 located between the airbag ring 2 and the one-way valve 10. The exhaust assembly includes an exhaust pipe 11, a sealing disc, and a sealing hole assembly. One end of the exhaust pipe 11 is connected to the mounting pipe 8. The outer peripheral wall of the sealing disc 14 is fixedly connected to the inner wall of the exhaust pipe 11. The sealing disc 14 is provided with an exhaust hole 13. The sealing hole assembly is movably inserted through the sealing disc 14. The sealing hole assembly can abut against the sealing disc 14 to seal the exhaust hole 13.

[0050] When medical staff assist children in wearing the inhalation mask 1, they can place the mask 1 against the patient's face and then pull the ear loop assembly to hang it around the patient's ears, thus securing the mask 1. Inflating the installation tube inflates the airbag ring 2 and airbag pad 4. The inflated airbag ring 2 increases the contact area with the patient's facial skin, and the inflated airbag pad 4 increases the contact area with the patient's ear skin, dispersing the pressure and preventing pressure marks on the child's face and ears from prolonged wear, thus improving comfort. When a child with a larger head pulls the ear loop assembly further and hangs it around their ear, the airbag pad 4 is compressed, forcing air into the airbag ring 2, making it larger to fit their facial skin. By inflating the installation tube and deflating through the exhaust assembly, the expansion size of the airbag ring and airbag pad can be adjusted to fit different children's facial and ear skin, improving versatility.

[0051] The oxygen mask assembly also includes an air inlet tube connected to the inhalation mask 1, which is used to assist the child in inhaling oxygen. The oxygen mask assembly also includes a nose bridge on the inhalation mask 1 to allow the child to wear the inhalation mask 1 smoothly. The oxygen mask assembly also includes an air outlet and an air valve on the inhalation mask 1 to allow the child to exhale gas.

[0052] To facilitate storage by ensuring the airbag ring 2 and airbag pad 4 are in an uninflated state before use, and to inflate them during use, and to prevent redness and pain on the face and ears of children caused by prolonged wearing of the inhalation mask 1, medical personnel can use an external syringe to draw in outside air, insert the syringe tip into the installation tube 8, and push the syringe to inject air through the installation tube 8 into the airbag ring 2 and airbag pad 4, causing both airbag ring 2 and airbag pad 4 to inflate and expand.

[0053] The mounting tube 8 is funnel-shaped, with the cross-sectional area of ​​one end of the mounting tube 8 being smaller than that of the other end. This funnel-shaped design allows injected gas to enter the airbag ring 2 and airbag cushion 4 more quickly, causing them to expand rapidly and improving the efficiency of syringe use for medical personnel.

[0054] A rubber pad is attached to the inner wall of the mounting tube 5, and the rubber pad is cylindrical. Due to the high coefficient of friction of the rubber pad, when the cylindrical injection head of the syringe is inserted into the cylindrical rubber pad, the injection head of the syringe can be stabilized in the inflation tube 5, so that the gas can be injected smoothly.

[0055] By moving the sealing assembly back and forth, the vent hole 13 can be continuously opened and closed, allowing the gas inside the airbag ring 2 and airbag pad 4 to be released. The contact area between the airbag ring 2 and airbag pad 4 and the child's skin can be adjusted according to the child's comfort level to achieve the best comfort required by the child.

[0056] In a preferred embodiment, this application may be further configured such that the ear strap assembly includes:

[0057] The elastic earband 3 has a receiving cavity, and its two ends are respectively connected to an airbag ring and an airbag pad 4; and,

[0058] Telescopic tube 7 is located inside the receiving cavity. One end of telescopic tube 7 is connected to airbag ring 2, and the other end is connected to airbag cushion 4.

[0059] The telescopic tube 7 is located within the receiving cavity, making the structure more compact and preventing it from interfering with the child's wearing of the inhalation mask 1. The outer wall of the telescopic tube 7 can be connected to the inner wall of the receiving cavity, and both ends of the telescopic tube 7 are connected to the airbag ring 2 and the airbag pad 4. Two ear loop assemblies are configured, each including two elastic ear loops 3. One end of each elastic ear loop 3 is connected to the airbag ring 2, and the other end is connected to both ends of the airbag pad 4, respectively, for easy placement on the child's ears. The telescopic tube 7 can be configured as one, with one of the two elastic ear loops 3 having a receiving cavity to accommodate it. Alternatively, two telescopic tubes 7 can be configured, with both elastic ear loops 3 having receiving cavities.

[0060] In a preferred embodiment, this application can be further configured such that: the sealing disc has a through hole in the middle, and the sealing assembly is a rotary sealing assembly, the rotary sealing assembly comprising:

[0061] The movable column 18 has its outer wall threadedly connected to the inner wall of the through hole; and,

[0062] The sealing plate 19 is fixedly connected to one end of the movable column 18. The sealing plate corresponds to the exhaust hole and can abut against the sealing disc 14.

[0063] By rotating the movable column 18, the sealing plate 19 can be pressed against the sealing disc 14 and block the exhaust hole 13. When the movable column is rotated in the opposite direction, the sealing plate can be disengaged from the sealing disc 14 and the exhaust hole 13 can be exposed, so that the gas in the airbag ring 2 and the airbag pad 4 can be discharged through the exhaust hole 13.

[0064] To improve the ease of operation of the movable column, in a preferred embodiment, the present application may further configure the sealing disc 14 to have a through hole 12 in the middle, and the sealing assembly is a press-to-seal assembly, which includes:

[0065] The outer wall of the movable part 17 is slidably connected to the inner wall of the through hole 12;

[0066] The sealing member 6 is fixedly connected to one end of the movable member 17, and the sealing member 6 corresponds to the vent 13 and can abut against the sealing disc 14; and...

[0067] One end of the elastic element 16 is fixedly connected to the other end of the movable element 17, and the other end is fixedly connected to the sealing disc 14.

[0068] Thus, by simply pressing and releasing the movable part 17, the sealing part 6 can be moved away from and the exhaust port 13 can be sealed, making operation more convenient. Among them, the elastic part 16 includes a coil spring.

[0069] In a preferred embodiment, the airbag ring can be further configured such that a fixing tube 5 is connected in communication with it, and the fixing tube 5 is threadedly connected to the mounting tube. This eliminates the need to fix the exhaust assembly and mounting tube 8 to each inhalation mask, saving costs and facilitating the replacement of the mounting tube 8 and exhaust assembly.

[0070] In a preferred embodiment, the present application may be further configured such that: the sealing member 6 is fixedly connected with a sealing rod 15 adapted to the vent hole 13, and the sealing rod 15 can penetrate the vent hole 13.

[0071] By setting the sealing rod 15, when the sealing member 6 and the movable member 17 are in motion, the sealing rod 15 can move within the vent hole 13, which can push out dust and impurities in the vent hole 13 and prevent the vent hole 13 from being blocked.

[0072] In a preferred embodiment, the present application may be further configured such that: the via 12 includes a first hole segment and a second hole segment, the inner wall of the first hole segment is slidably connected to the outer wall of the movable member 17, the sealing member 6 is arranged in a frustum shape, and the second hole segment is at least partially adapted to the sealing member 6.

[0073] When the movable part 17 is pressed and released, the sealing part 6 will quickly approach and collide with the sealing disc 14 under the elastic force of the elastic part 16. By setting the frustum-shaped sealing part 6 and the matching second hole section, the surface of the sealing part 6 in contact with the inner wall of the second hole section can be prevented from being perpendicular to its own direction of movement, thereby reducing the impact force on the sealing part 6 after contact with the inner wall of the second hole section, preventing damage to the sealing part 6, and improving the service life of the sealing part 6. Furthermore, as the frustum-shaped sealing part 6 gradually moves away from the sealing disc 14, the sealing part 6 will gradually expose the vent hole 13, allowing the gas in the airbag ring 2 and airbag pad 4 to be slowly discharged. This prevents the gas in the airbag ring 2 and airbag pad 4 from being discharged too quickly due to the vent hole 13 being exposed too quickly, making it difficult to carefully feel the comfort. This allows the patient to adjust the airbag ring 2 and airbag pad 4 to the optimal comfort level.

[0074] In a preferred embodiment, the movable member 17 can be further configured as follows: the first hole segment is rectangular. This prevents the movable member 17 from rotating within the through hole 12 after the sealing rod 15 disengages from the vent hole 13, and allows the sealing rod 15 to be accurately inserted back into the vent hole 13.

[0075] In a preferred embodiment, the sealing member 6 can be further configured such that the portion of the sealing member 6 away from the movable member 17 extends out of the second hole and is fitted with a protective bladder 9, which can abut against the sealing disc 14. The protective bladder 9 not only improves the sealing performance of the sealing member 6 to the exhaust hole 13, but also cushions the sealing member 6 when it contacts the sealing disc 14, further preventing damage to the sealing member 6 and improving its service life.

[0076] Working principle: When medical staff assist children in wearing the inhalation mask 1, they can fit the inhalation mask 1 against the patient's face, and then pull the elastic ear loops 3 to hang the elastic ear loops 3 and air cushions 4 on the patient's ears to fix the inhalation mask 1. Children's facial skin is relatively delicate, and prolonged wearing of the inhalation mask can cause pressure marks on the skin. Moreover, prolonged pulling of the ear loops can cause redness, swelling and pain in the child's ears. At this time, medical staff can hold an external syringe to draw in external air, move the syringe head to insert into the installation tube 8, and then push the syringe to inject air into the air cushion ring 2. The air cushion ring 2 is connected to the air cushion 4 through the telescopic tube 7. After the air is injected into the air cushion ring 2, the air cushion ring 2 and the air cushion 4 will expand and increase the contact area with the patient's skin, avoiding pressure marks, redness, swelling and pain caused by prolonged wearing of the inhalation mask, and improving the comfort of wearing it.

[0077] When the airbag cushion 4 and airbag ring 2 need to be depressurized, the movable part 17 can be pressed manually. The movable part 17 drives the sealing part 6 to move, canceling the seal on the exhaust hole 13. At this time, the gas inside the airbag ring 2 and airbag cushion 4 can be discharged through the exhaust hole 13 and exhaust pipe 11, which makes it convenient to adjust the size of the airbag ring 2 and airbag cushion 4, further improving the comfort when wearing them.
