[0029] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0030] First embodiment:

[0031] This embodiment discloses an oxygen inhalation tube with adjustable flow rate, including an oxygen regulator. An inlet channel 110 and an outlet channel 210 are interconnected within the oxygen regulator. The inlet channel 110 is arranged along a first direction, and the second channel is arranged along a second direction. The first and second directions form an angle. A regulating valve 300 is provided at the connection between the inlet channel 110 and the outlet channel 210. The regulating valve 300 is at least partially exposed outside the oxygen regulator. The inlet channel 110 is connected to an external air supply device, and the outlet channel 210 is connected to a nasal catheter 500.

[0032] The above example is only a possible implementation method and does not limit the present invention. Please continue to refer to the subsequent embodiments for understanding.

[0033] Second embodiment

[0034] Based on the above embodiments, in this example, Figure 1-3 The oxygen regulator will be described in detail.

[0035] The oxygen regulator includes a first pipe 100 arranged along a first direction and a second pipe 200 arranged along a second direction. In this example, the first direction is a horizontal direction and the second direction is a vertical direction. For details, please refer to Figure 1 Further combined with Figure 2-3 As shown in the internal structure, the first pipe 100 is horizontally arranged and has the air inlet channel 110 inside, the second pipe 200 is vertically arranged and has the air outlet channel 210 inside, the first pipe 100 is connected to the middle section of the second pipe 200, and then the air inlet channel 110 is connected to the air outlet channel 210.

[0036] Specifically, the wall surface of the first pipe 100 and the wall surface of the second pipe 200 are integrally formed, and the air inlet channel 110 is connected to the air outlet channel 210 to form a T-shaped pipe, wherein one end of the first pipe 100 is an air inlet 120, and the air inlet 120 is used to connect to an external gas transmission device, such as an oxygen machine, and the other end of the first pipe 100 is provided with a through hole 130, and the regulating valve 300 is passed through the through hole 130. More specifically, the outer wall surface of the air inlet 120 is provided with a first threaded surface 121, and the inner wall surface of the through hole 130 is provided with a second threaded surface 131. The regulating valve 300 includes a threaded rod 310 threadedly connected to the second threaded surface 131. For better explanation, this example uses the threaded connection of the threaded rod 310 as the boundary. The side of the threaded rod 310 arranged in the air inlet channel 110 is the valve body 320, and the side arranged outside the air inlet channel 110 is the regulating body 330; the outer wall of the valve body 320 at one end facing the air outlet is completely fitted with the inner wall of the air inlet channel 110.

[0037] As mentioned above, the air inlet pipe and the air outlet pipe are connected to form an L-shaped pipe. Figure 3 As shown, the valve body 320 can be moved to the bottom of the gas outlet pipe in at least one state, that is, the valve body 320 can separate the horizontal pipe from the gas outlet pipe in at least one state.

[0038] It is understood that by screwing and adjusting the adjusting body 330, the position of the valve body 320 in the pipeline can be effectively changed. Twisting the adjusting body 330 causes the threaded rod 310 to move forward or backward along the threaded connection, thereby causing the valve body 320 to move axially along the pipeline. When the adjusting body 330 is screwed in one direction, the valve body 320 moves toward the air inlet channel 110, thereby increasing the opening between the valve body 320 and the air outlet channel 210 and increasing the oxygen flow rate. Conversely, when the adjusting body 330 is screwed in the other direction, the valve body 320 moves toward the air outlet channel 210, reducing the opening and thus reducing the oxygen flow rate. In this way, the user can precisely control the oxygen flow rate as needed, achieving flexible adjustment of the oxygen supply.

[0039] Third embodiment

[0040] exist Figure 2-3In the preferred example shown, the diameter of the valve body 320 is larger than that of the threaded rod 310. The valve body 320 includes a first protrusion 321 and a second protrusion 322. The first protrusion 321 is disposed on the side facing the air outlet pipe, and the length of the first protrusion 321 in the first direction is at least equal to the inner diameter of the air outlet hole 130. The length of the second protrusion 322 in the first direction can be slightly shorter than that of the second protrusion 322. In this preferred example, the first protrusion 321 can completely block the air outlet channel 210. When the adjustment body 330 is rotated to move the valve body 320 toward the air outlet channel 210, the first protrusion 321 enters the air outlet channel 210, completely filling the channel inner diameter, thereby completely shutting off the oxygen flow.

[0041] Continue to refer Figure 3 In some specific examples, the air outlet channel 210 is further provided with a rib 211 for clamping the nasal catheter 500. Figure 1 As shown, the outer wall of the regulating body 330 and the air outlet channel 210 are provided with a plurality of stripes for increasing friction. Figure 3 As shown, the gas outlet is threadedly connected to the gas outlet end 400 of the oxygen machine (only the connection cap of the gas outlet end 400 is shown in the figure).

[0042] refer to Figure 1 As shown, the air outlet channel 210 is connected to the nasal catheter 500. Figure 1 Omitting the subsequent pipeline, it is understandable that Figure 1 The C-terminal of Figure 4 At the D end in FIG, the oxygen regulator is connected to the nasal catheter 500. In the subsequent examples, a structure of the nasal catheter 500 is specifically described.

[0043] Fourth embodiment

[0044] Based on the above embodiments, Figure 4-5In the structure shown, two first branch tubes 510 extend from the tube of the nasal catheter 500. The first branch tubes 510 are designed to be inserted into the patient's nasal cavity. In this example, the distal end of the first branch tube 510 has a rounded end structure 511, and the diameter of the first branch tube 510 gradually decreases from the starting end to the rounded end structure 511. The first branch tube 510 is provided with several micropores (not shown) for the passage of oxygen, wherein the rounded end structure 511 is provided with micropores. It is understood that the rounded end structure 511 of the first branch tube 510 can improve user comfort. Traditional cylindrical tubes with one end open may cause irritation or damage to the inner wall of the nasal cavity during insertion. However, the rounded end structure 511 is designed with a smooth shape to reduce friction and irritation on the nasal mucosa. In addition, the gradual decrease in tube diameter from the starting end to the rounded end structure 511 helps it more naturally adapt to the shape of the nasal cavity, providing a more comfortable fit, thereby significantly improving patient comfort.

[0045] In addition, the micropores provided on the first branch pipe 510 are evenly distributed on the round head structure 511 and the surrounding wall surface, which can evenly disperse the inflow of oxygen and avoid the oxygen being concentrated at one point and outputting, causing unnecessary pressure or discomfort.

[0046] The nasal cannula 500 is further provided with a second branch tube 520, which is connected to the nasal cannula 500. The second branch tube 520 is located opposite the first branch tube 510. It is understood that the second branch tube 520 is located opposite the first branch tube 510 so that the second branch tube 520 faces the patient's mouth. The second branch tube 520 is provided with an auxiliary ventilation hole 521.

[0047] It is understood that in certain medical situations, such as after ENT surgery, such as nasal surgery, the patient may temporarily be unable to breathe normally through the nose and therefore need to inhale oxygen through the mouth. In this case, the second branch tube 520 is located on the opposite side of the nasal cannula 500, facing the patient's mouth. The auxiliary vent 521 provided therein facilitates the output of oxygen, ensuring that the patient can effectively inhale oxygen through the mouth.

[0048] Fifth embodiment

[0049] Based on the above embodiment, continue to refer to Figure 4-5In this example, the second branch tube 520 includes a manifold section 522 connected to the nasal catheter 500. A first tube balloon 523 extends from the manifold section 522. The first tube balloon 523 is connected to the manifold section 522 on its vertical upper side, and a second tube balloon 524 extends from its horizontal side. The second tube balloon 524 is further connected to a bite portion 525, which is provided with the auxiliary ventilation hole 521. Specifically, the bite portion 525 is a hollow air balloon.

[0050] Combine Figure 5 In the structure shown, two auxiliary ventilation holes 521 are provided on the upper and lower sides of the bite portion 525, and a flap 526 extends from the hole wall of the auxiliary ventilation hole 521, and the free end of the flap 526 extends to the interior of the airbag, so that the flap 526 is curved. It can be understood that the flap 526 is designed to control the flow direction of the gas to ensure that the gas can be flexibly distributed according to the patient's breathing needs. When the patient does not need to breathe through the mouth, the flap 526 can effectively block the gas inside the bite portion 525 due to the curved design of its free end, preventing the gas from flowing out through the auxiliary ventilation hole 521. At this time, oxygen is mainly supplied through the first branch pipe 510, thereby meeting the patient's normal breathing through the nasal cavity.

[0051] When a patient needs to breathe through the mouth, such as after nasal surgery or when the nasal cavity is temporarily unsuitable for breathing, the patient can achieve ventilation through the upper and lower flaps 526 of the bite portion 525. The bite causes the curved portion of the flap 526 to deform or move, thereby opening the auxiliary ventilation hole 521 and allowing air to flow out of the bite portion 525 and into the mouth.

[0052] Therefore, the hollow structure of the bite portion 525 combined with the flap 526 provides a flexible storage space for gas, allowing for instant adjustment of gas output to meet rapidly changing breathing needs, ensuring that the patient can receive appropriate oxygen supply in all situations, whether through the nasal cavity or the mouth.

[0053] exist Figure 4-5 In the specific structure shown, the width of one side of the engaging portion 525 connected to the second tube bag 524 is smaller than the other side, which is more in line with the human oral structure and is convenient for being held in the mouth.

[0054] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
