Detailed implementation manners

[0024] The present utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. The same components are denoted by the same reference numerals.

[0025] Figures 1-4 This is the first embodiment of the present utility model. A high-flow humidified oxygen therapy nasal catheter includes an intake pipe head 1. The intake pipe head 1 includes an adjustment section 2 and connection sections 3 located on both sides of the adjustment section 2. The adjustment section 2 is a corrugated pipe, and two nasal oxygen heads 4 are symmetrically arranged on the adjustment section 2.

[0026] It further includes an adjustment block 5. The adjustment block 5 is provided with an eccentric rotation hole 6. The connection section 3 passes through the adjustment block 5 and is rotatably connected to the adjustment block 5. The adjustment block 5 is used to abut against the human body and support the connection section 3. The adjustment block 5 rotates relative to the connection section 3 to adjust the relative support position of the connection section 3 with respect to the human body.

[0027] Furthermore, the adjustment block 5 is made of a soft material, specifically medical silicone, to improve the comfort level when contacting the human body.

[0028] It further includes an input pipe 7. The input pipe 7 is connected to the connection section 3 and is used to convey air flow into the connection section 3. The end of the input pipe 7 away from the connection section 3 is used to be connected to a humidification treatment instrument.

[0029] It further includes an elastic band 8. The elastic band 8 is connected to the intake pipe head 1 and is used to fix to the human body.

[0030] During use, the intake pipe head 1 is worn through the elastic band 8, and at the same time, air flow is input through the input pipe 7. This air flow is respectively conveyed into the nasal cavity through the intake pipe head 1 and the nasal oxygen heads 4. The patient can stretch, compress or bend the corrugated pipe according to the nasal cavity interval and the protrusion of the maxilla of his own, so as to adjust the mutual interval and the insertion angle of the two nasal oxygen heads 4. At the same time, the adjustment block 5 is used to support the support section, and further adjust the insertion angle of the two nasal oxygen heads 4. At the same time, the setting of the adjustment block 5 can ensure the contact degree between the connection section 3 and the human body, so as to prevent the nasal oxygen heads 4 from falling off.

[0031] When the patient needs to adjust the insertion angle of the nasal oxygen head 4, on the basis of adjusting the corrugated pipe, the adjusting block 5 can be rotated. Since the rotation hole 6 is eccentrically arranged, when the adjusting block 5 is rotated, it can control the areas with different thicknesses of the adjusting block 5 to contact the human body, so as to realize the adjustment of the supporting position of the connecting section 3, and further realize the further adjustment of the insertion angle of the nasal oxygen head 4.

[0032] Preferably, the cross-section of the adjusting block 5 is circular. The circular shape can ensure contact with the arc surface of the patient's skin, thereby improving the wearing comfort and facilitating long-term wearing and use. In another embodiment, the cross-section of the adjusting block 5 can also be set as a polygon.

[0033] Preferably, a locking mechanism 9 is provided at the connection between the connecting section 3 and the adjusting block 5. The locking mechanism 9 is used to adjust the rotation / locking of the adjusting block 5 relative to the connecting section 3.

[0034] Through the setting of the locking mechanism 9, it can be avoided that the adjusting block 5 deflects and slips relative to the connecting section 3 during the wearing process, so as to ensure that the supporting position of the adjusting block 5 on the connecting section 3 remains unchanged and the insertion angle of the nasal oxygen head 4 remains unchanged.

[0035] Preferably, the locking mechanism 9 includes a limiting ring 10 and a plurality of first clamping blocks 11 arranged around the connecting section 3. The plurality of first clamping blocks 11 are evenly distributed, and a first clamping groove 12 is formed between adjacent first clamping blocks 11. An installation groove 13 is formed at the end of the adjusting block 5. The limiting ring 10 is fixedly arranged in the installation groove 13. The limiting ring 10 is provided with a second clamping block 14 corresponding to the clamping groove 12. The second clamping block 14 is used to clamp the first clamping groove 12 to limit the rotation of the limiting ring 10 relative to the connecting section 3. Through the cooperation between the first clamping groove 12 formed by the plurality of first clamping blocks 11 and the second clamping block 14, the adjusting block 5 can obtain a plurality of adjustment angles relative to the connecting section 3, so as to improve the overall applicability.

[0036] In the initial state, the second clamping block 14 is clamped with the first clamping groove 12. Since the limiting ring 10 is fixedly connected with the installation groove 13, the adjusting block 5 and the connecting section 3 are locked with each other. When the adjusting block 5 needs to be adjusted, by moving the adjusting block 5 on the connecting section 3, the second clamping block 14 is separated from the first clamping groove 12, so that the limiting ring 10 can rotate relative to the connecting section 3, and then the adjusting block 5 can be rotated and adjusted according to the needs of the user. After the adjustment is completed, the adjusting block 5 is moved again to make the second clamping block 14 be clamped with the first clamping groove 12 again to realize re-locking.

[0037] Preferably, a limiting plate 15 is provided on the side of the connecting section 3 corresponding to the first clamping block 11 away from the adjusting block 5. The limiting plate 15 is used to abut against the limiting ring 10 to limit the moving range of the limiting ring 10. By providing the limiting plate 15, it can be avoided that the limiting ring 10 completely passes through the first clamping block 11 during the adjustment process, resulting in the locking failure of the limiting ring 10, thereby ensuring the fixing effect of the limiting ring 10.

[0038] Preferably, the adjusting section 2 is wrapped with a soft gel 16, which can effectively avoid the discomfort caused by the edge of the corrugated pipe pressing on the skin after bending, so as to improve the overall wearing comfort.

[0039] Preferably, an annular groove 17 is provided in the middle section of the adjusting block 5. By providing the groove 17, it is convenient for the adjusting block 5 to bend, thereby improving the degree of attachment to the human body and the comfort during wearing.

[0040] Figure 5 This is the second embodiment of the present invention. The difference from the first embodiment is that a cushion block 18 is provided at one end of the connecting section 3 away from the adjusting section 2. One side of the cushion block 18 is used to abut against the human body, and the other side forms an inclined surface 19. A plurality of second clamping grooves 20 are arranged on the inclined surface 19. The second clamping grooves 20 are used to clamp the connecting section 3. The connecting section 3 contacts the concave part of the human jaw bone through the cushion block 18 to ensure the tightness of the air inlet head 1 and thus avoid falling off.

[0041] The above are only the preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements should also be regarded as the protection scope of the present invention.
