[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-3 This utility model provides a technical solution: a headband-type adjustable ventilator nasal tube, including a mesh cover 1 and a nasal tube 2. The mesh cover 1 covers the head of the child outside. A fixing strap 3 is installed below the mesh cover 1. Side connecting straps 4 are installed on both the left and right sides of the fixing strap 3. A fixing plate 5 is installed on the side wall of the side connecting strap 4. The nasal tube 2 is snapped onto the fixing plate 5. The nasal tube 2 is connected to the external ventilator.

[0024] This device can be worn on the child's head via a mesh cover 1, a side connecting strap 4, and a chin strap 8, and the nasal tube 2 can be fixed by the fixing plate 5 on the side connecting strap 4.

[0025] This device ensures breathability by placing a mesh cover 1 over the child's head, and a chin strap 8 below it ensures the child's stability after wearing it.

[0026] Nasal tube 2 includes a fixing tube 21, a connecting tube 22, an insertion tube 23, and a nasal insertion tube 24. The left side of the fixing tube 21 is inserted into one end of the connecting tube 22, and the right side of the fixing tube 21 is inserted into one end of the insertion tube 23. The other ends of the connecting tube 22 and the insertion tube 23 are connected to the external ventilator. The upper walls of the fixing tube 21 and the insertion tube 23 are both inserted into the nasal insertion tube 24. The two nasal insertion tubes 24 are inserted into the two nostrils of the external patient, respectively.

[0027] Both the connecting tube 22 and the insertion tube 23 are fitted with a sealing ring 6 at one end inside the fixing tube 21;

[0028] By moving the position of the intubation tube 23, the distance between the two nasal intubation tubes 24 can be adjusted, thereby improving the flexibility of the device and making it suitable for different children.

[0029] By setting the sealing ring 6, the airtightness of the nasal tube 2 can be guaranteed, preventing air leakage.

[0030] Specifically, the side wall of the fixing plate 5 is equipped with an arc-shaped locking block 7, and the connecting pipe 22 and the insertion pipe 23 can be respectively locked into the two arc-shaped locking blocks 7.

[0031] Specifically, a jaw strap 8 is installed on the lower wall of the two side connecting straps 4, and the jaw strap 8 is placed on the lower jaw of the external patient.

[0032] The lower jaw band 8 is made of elastic material.

[0033] Specifically, a fixing block 9 is installed on the front side wall of the fixing tube 21, and a sliding groove 10 is provided on the side wall of the fixing block 9. A first insertion rod 11 is installed on the front side wall of the insertion tube 23. The first insertion rod 11 can be inserted into the sliding groove 10, and a toothed groove 12 is provided on the side wall of the first insertion rod 11.

[0034] A second insert rod 13 is inserted into the side wall of the fixing block 9. One end of the second insert rod 13 located in the slide groove 10 is equipped with a protruding tooth 14 that mates with the tooth groove 12. A spring 15 is sleeved on the outside of the second insert rod 13. One end of the spring 15 is in contact with the inner side wall of the slide groove 10, and the other end of the spring 15 is in contact with the side wall of the protruding tooth 14.

[0035] By engaging the protruding teeth 14 on one side of the second insertion rod 13 with the grooves 12 on the first insertion rod 11, the position of the insertion tube 23 can be fixed, preventing changes in the distance between the two nasal insertion tubes 24 after the child wears the device.

[0036] Specifically, a medical adhesive patch 16 is installed on the rear side wall of the fixing tube 21, which can be attached to the philtrum of the child.

[0037] By attaching the medical adhesive patch 16 to the child's philtrum, the nasal tube 2 in this device can be fixed in place, preventing the child from moving around and causing the nasal tube 24 to fall out of the child's nasal cavity.

[0038] Specifically, the side wall of the side connecting strip 4 is provided with an ear relief hole 17;

[0039] The child's ear can pass through the side connecting strap 4 through the ear clearance hole 17, making it more comfortable to wear.

[0040] Working principle: The device is worn on the child's head through the mesh cover 1, fixing strap 3, side connecting strap 4 and chin strap 8. Then, the nasal tube 2 is adjusted according to the distance between the child's two nostrils.

[0041] When adjusting the nasal tube 2, first pull the second insert rod 13 outward so that its protrusion 14 disengages from the tooth groove 12. Then pull the tube 23 to adjust the distance between the two nasal tubes 24. After the adjustment is completed, release the second insert rod 13. Under the action of the spring 15, the second insert rod 13 moves inward so that its protrusion 14 is inserted into the tooth groove 12, thus fixing the position of the tube 23.

[0042] After the nasal tube 2 is adjusted, insert the nasal cannula 24 in the nasal tube 2 into the child's nostril, and connect the connecting tube 22 and the cannula 23 to the external ventilator. The ventilator provides a certain positive pressure to the child's breathing, increases the functional residual capacity, and ensures that the newborn's airway and alveoli are in an expanded state in case of abnormalities, thus preventing alveolar collapse.
