[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Embodiment, this embodiment provides an oxygen inhalation tube fixing device, including: a fixing piece for fixing the oxygen inhalation tube and a strap 3 connected to the fixing piece and capable of surrounding the back of the head, the fixing piece includes a U-shaped outer sleeve 1 and a U-shaped inner sleeve 2, such as Figure 1 As shown, there are two fixing parts. When in use, the inner spaces of the two U-shaped inner ferrules 2 are clamped on the outer walls of the oxygen tube on both sides of the nasal vestibule. The inner space width of the U-shaped inner ferrule 2 is just equal to the outer diameter of the oxygen tube. The oxygen tube can be easily inserted into the inner space of the U-shaped inner ferrule 2 without causing the oxygen tube to be compressed and affect the oxygen delivery. Then, the U-shaped inner ferrule 2 is clamped on the inner wall of the U-shaped outer ferrule 1, and the two free ends of the U-shaped inner ferrule 2 are brought together and the distance between the two free ends of the U-shaped inner ferrule 2 is reduced. The two free ends of the U-shaped inner ferrule 2 are symmetrically pressed against the upper sides of the outer wall of the oxygen tube relative to the side walls. In this way, the oxygen tube can be stably clamped, while preventing the oxygen tube from being compressed and unable to supply sufficient oxygen. Then, the strap 3 is used to wrap around the back of the head to limit the position of the fixing part below the nasal vestibule, ensuring that the oxygen outlet of the oxygen tube is inserted into the nasal vestibule, thereby fixing the position of the oxygen tube and preventing it from falling off. This solves the problem of infants or young children being unable to breathe oxygen normally due to limb movement causing the oxygen tube to fall off from the nasal vestibule.

[0023] The axial length of the U-shaped inner ferrule 2 is 5-10 times the axial length of the U-shaped outer ferrule 1. The purpose of this arrangement is to provide a relatively large clamping surface of the U-shaped inner ferrule 2 for clamping the oxygen tube, thereby preventing the oxygen tube from curling at the clamping position and failing to provide sufficient oxygen.

[0024] In the first embodiment of the fixing member, both outer walls of the U-shaped inner ferrule 2 are provided with limit slots 21, and the upper end of the inner side wall of the U-shaped outer ferrule 1 is fixed with an extension block 13 engaged with the limit slots 21, such as Figure 3 As shown, after the U-shaped inner ferrule 2 is inserted into the inner space of the U-shaped outer ferrule 1, the two extension blocks 13 can bring the two free ends of the U-shaped inner ferrule 2 together and reduce the distance between the two free ends of the U-shaped inner ferrule 2, so as to ensure that the oxygen tube is not easily separated from the U-shaped inner ferrule 2, and then fix the position of the oxygen tube by the binding band 3. After the oxygen inhalation is completed, the U-shaped inner ferrule 2 is removed from the inner wall of the U-shaped outer ferrule 1, and the two free ends of the U-shaped inner ferrule 2 are reset, and the oxygen tube can be easily removed.

[0025] In the second embodiment of the fixing member, the outer walls of both sides of the U-shaped inner ferrule 2 are provided with limit slots 21, and the upper end of the inner side wall of the U-shaped outer ferrule 1 is rotatably provided with an I-shaped wheel 14 engaged with the limit slots 21, such as Figure 4 and Figure 5 As shown, after the U-shaped inner ferrule 2 is inserted into the inner space of the U-shaped outer ferrule 1, the two I-shaped wheels 14 can bring the two free ends of the U-shaped inner ferrule 2 together and reduce the distance between the two free ends of the U-shaped inner ferrule 2, so as to ensure that the oxygen tube is not easily separated from the U-shaped inner ferrule 2, and then fix the position of the oxygen tube through the strap 3, and the I-shaped wheel 14 can roll along the limiting groove 21 to reduce the friction resistance when the U-shaped inner ferrule 2 is inserted into the inner side of the U-shaped outer ferrule 1. After the oxygen inhalation is completed, the U-shaped inner ferrule 2 is removed from the inner wall of the U-shaped outer ferrule 1, and the two free ends of the U-shaped inner ferrule 2 are reset, and the oxygen tube can be easily removed.

[0026] In addition, a connecting block 11 is provided on the outer wall of one side of the end of the U-shaped outer ferrule 1, a U-shaped notch is provided at the end of the connecting block 11, a protrusion 12 is provided at the end of one side wall in the U-shaped notch, and a groove matching the protrusion 12 is provided at the end of the other side wall in the U-shaped notch. Two straps 3 are provided, and both ends of the two straps 3 are provided with hollow rings, such as Figure 2 As shown, the bandage 3 is detachably connected to the connecting block 11, the U-shaped notch of the connecting block 11 is stretched open, the protrusion 12 is separated from the groove, the hollow loop of the bandage 3 is put into the U-shaped notch, the stretched U-shaped notch is released, the protrusion 12 is reset and snapped into the groove, and the opening of the U-shaped notch is closed. After oxygen inhalation is completed, the bandage 3 is taken out from the U-shaped notch of the connecting block 11, and a new bandage 3 can be replaced for reuse to avoid cross infection caused by repeated use. The bandage 3 is preferably made of elastic braided band or medical sterile gauze.

[0027] Furthermore, one end of one of the straps 3 is provided with a furry surface at one end away from the hollow loop, and the other end of the strap 3 is provided with a hook surface at one end away from the hollow loop, and the hook surface is adhered to the furry surface. The two straps 3 are respectively wrapped around the face and the upper part of the auricle to the back of the head, and the two straps 3 are bound by adhering the hook surface and the furry surface. The adhesion position of the hook surface and the furry surface is adjusted according to the size of the patient's head circumference to ensure moderate tightness and prevent it from falling off.

[0028] And if Figure 1 As shown, an expansion portion is provided at one end of the two straps 3 away from the hollow ring, and the width of the expansion portion is 5-10 times the width of the strap 3. The advantage of setting the expansion portion with a width of 5-10 times the width of the strap 3 itself at the binding end of the strap 3 is that it is attached to the back of the head with a wider coverage area, preventing the strap 3 from being wrapped around the head and rolling down to the cervical spine due to its thinness, causing the oxygen tube to fall off.

[0029] An anti-dropping string 31 may also be connected between the two extension parts, so that the two binding straps 3 are connected as one, preventing one from being lost and the other from being unusable.

[0030] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
