Its equipment structure mainly includes: an air-oxygen mixer, a gas heater, a heated breathing tube, and a nasal inlet tube connected in sequence. Among them, the air-oxygen mixer is used to generate an air-oxygen mixed gas with an appropriate proportion, the gas heater is used to heat the air-oxygen mixed gas, and the heated breathing tube is used to guide the heated air-oxygen mixed gas to the nasal inlet tube and introduce it into the patient's nose through the nasal inlet tube. The problem with this equipment structure is that when performing nasal high-flow oxygen therapy, the patient usually needs to lie on his back or sit on the bed, which results in the need to give a larger design length to the tube body of the heated breathing tube, and the weight of the tube body is heavy and presses on the patient's upper body. The patient will feel uncomfortable when using the device because the upper body is compressed by the tube for a long time. In particular, the heated breathing tube will cause inconvenience to the patient when eating.

DETAILED DESCRIPTION

[0030] The following is an explanation of the implementation of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention.

[0031] Example 1, please refer to Figure 2 :

[0032] A high-flow oxygen inhalation nasal cannula device comprises: an air-oxygen mixer 100, a gas heater 200, a heated breathing tube 300, a nasal inlet tube 400 and a pulling assembly 500.

[0033] The air-oxygen mixer 100, the gas heater 200, the heated breathing tube 300, and the nasal inlet tube 400 are connected in sequence. The air-oxygen mixer 100 is used to generate a mixed gas of air and pure oxygen according to a preset ratio; the gas heater is used to heat the mixed gas generated and output by the air-oxygen mixer 100; the heated breathing tube 300 is used to conduct the heated mixed gas output by the gas heater to the nasal inlet tube 400, and the input end of the nasal inlet tube 400 is connected to the output end of the gas heater 200; the output end of the nasal inlet tube 400 extends into the patient's nostrils. The nasal inlet tube 400 is fixed to the patient's head by a fixing belt 410.

[0034] The pulling assembly 500 is connected to the heated breathing tube 300 and is used to provide a pulling force for pulling the tube body of the heated breathing tube 300 upward in a vertical direction.

[0035] By adopting this technical solution: during the process of high-flow nasal oxygen therapy, firstly, air and oxygen are introduced into the air-oxygen mixer 100 through the catheter respectively, and the air-oxygen mixer 100 mixes the air and oxygen according to a preset ratio to form a mixed gas, which enters the gas heater 200, and the gas heater 200 heats the mixed gas to a suitable temperature and inputs it into the heated breathing tube 300. The heated mixed gas reaches the nasal inlet 400 along the heated breathing tube 300, and enters the patient's nasal cavity to realize high-flow nasal oxygen therapy. In the above process, since the pulling component 500 always maintains the pulling force applied to the heated breathing tube 300 in the vertical direction to pull its tube body upward, the weight of the heated breathing tube 300 pressing on the patient's upper body is reduced, and the pulling feeling caused by the fixing belt 410 on the patient's face is reduced, thereby improving the patient's physical experience during treatment.

[0036] In this example, an intermediate conducting tube 600 is provided between the output end of the heating breathing tube 300 and the input end of the nasal inlet tube 400. The intermediate conducting tube 600 is preferably a rigid tube body. The heating breathing tube 300 and the nasal inlet tube 400 are both bendable flexible tube bodies. The pulling assembly 500 includes: a support rod 510, a mechanical arm 520, a support platform 530 and a storage basket 540.

[0037] The rod body of the support rod 510 extends in a vertical direction, a support seat 511 is connected to the bottom of the rod body of the support rod 510, and a universal wheel 512 is provided at the bottom of the support seat 511. The mechanical arm 520 includes a first connecting rod 521 and a second connecting rod 522 connected in sequence. Specifically, the first connecting rod 521 is configured to extend in a horizontal direction, a clamping sleeve 523 is provided at the first end of the first connecting rod 521, the clamping sleeve 523 is sleeved on the rod body of the support rod 510, and a tightening piece 524 for adjusting the tightness of the clamping sleeve 523 is provided on the clamping sleeve 523. The first end of the second connecting rod 522 is movably connected to the second end of the first connecting rod 521 through a first rotating joint 525, and the second end of the second connecting rod 522 is movably connected to the intermediate conducting pipe 600 through a second rotating joint 526;

[0038] The first rotating joint 525 is configured to realize the vertical rotation of the second connecting rod 522 relative to the second end of the first connecting rod 521; the second rotating joint 526 is configured to realize the horizontal rotation of the intermediate conductive tube 600 relative to the second end of the second connecting rod 522.

[0039] The support platform 530 is fixedly mounted on the rod body of the support rod 510 and is located below the clamping sleeve 523. The support platform 530 is used to place the gas heater 200. The storage basket 540 is fixedly mounted on the rod body of the support rod 510 and is disposed below the support platform 530. (For example, in practice, the air-oxygen mixer 100 can be placed in the storage basket 540).

[0040] By adopting this technical solution: during the nasal high-flow oxygen therapy, firstly, the horizontal height of the clamping sleeve 523 on the support rod 510 is adjusted accordingly according to the actual height position of the patient on the bed (clinically, many beds have the function of adjusting the height), so that it is slightly higher than the actual height position of the patient on the bed, and at the same time, the first rotating joint 525 is operated to rotate, so that the rod body of the second connecting rod 522 rotates in a vertical plane with the first rotating joint 525 as the center, and then the rod body of the second connecting rod 522 is rotated to a height higher than the patient on the bed. At this time, the second connecting rod 522 realizes the pulling force of the intermediate conductive tube 600 to pull upward through the second rotating member. Therefore, the load on the patient's body, especially the patient's neck, caused by the tube body of the heated breathing tube 300 can be reduced during the nasal high-flow oxygen therapy.

[0041] When the patient needs to eat during treatment, the second rotating joint 526 is operated to rotate, so that the second connecting rod 522 and the first connecting rod 521 rotate in a horizontal plane with the second rotating joint 526 as the center, and the universal wheel 512 is used to synchronously move the support rod 510. Then, the heated breathing tube 300 and the nasal inlet tube 400 are driven to bend to different degrees to the side and rear of the patient's head to prevent the tube body from affecting the patient's eating.

[0042] The above is a detailed description of the embodiments of the present invention in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Even if various changes are made to the present invention, if these changes fall within the scope of the claims of the present invention and their equivalents, they still fall within the protection scope of the present invention.
