Description

Technical Field

[0001] The present invention relates to the technical field of oxygen humidification, and in particular to an oxygen humidification device for respiratory function. Background Art

[0002] Oxygen humidification devices are widely used in the treatment of various respiratory diseases, including colds, pneumonia, chronic obstructive pulmonary disease, bronchiectasis, asthma, respiratory failure, etc. Oxygen itself is a dry, pure gas without humidity. Direct inhalation of dry oxygen can cause dryness of the patient's respiratory mucosa, impaired ciliary function, and even cause discomfort, such as dry nasal cavity, pain, cough, etc. Therefore, oxygen needs to be humidified to reduce irritation to the respiratory tract; bubble humidification is one of the most commonly used oxygen humidification methods in clinical practice. Its principle is to pass oxygen into the humidification liquid through the sieve holes to form small bubbles, increase the contact area between oxygen and water, and thus achieve humidification. It is recommended to use sterile water for injection, distilled water, or purified water in oxygen humidification devices to ensure humidification effect and patient safety.

[0003] To ensure the humidification effect and patient safety, traditional oxygen humidifiers usually require manual regular inspection of the humidification liquid level and manual addition, and the humidification liquid needs to be replaced once a day to prevent bacterial growth. Each regular water addition and daily water change requires the humidification cup to be opened and closed, which not only increases the workload of medical staff and reduces efficiency, but also increases the risk of infection. Moreover, the humidification cup requires different volumes based on different patients. In general hospital wards, medium-volume humidification cups can be used for patients' routine oxygen therapy; in intensive care units, some patients with more serious conditions who require long-term high-flow oxygen inhalation can use large-volume humidification cups to better ensure the humidification effect of oxygen. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an oxygen humidifier for respiratory function. By arranging a water adding component and an adjusting component, the water adding component can not only improve the efficiency of regular water adding, but also can realize automatic water adding without opening the humidifier cup during the water adding process; the adjusting component can not only adjust the humidification processing volume of the humidifier cup, but also assist the humidifier cup in convenient water change.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0008] Optionally, the lower group long tube, the lower group short tube, the upper group long tube and the upper group short tube are all made of polyvinyl chloride (PVC) with the same tube diameter, and all extend to the bottom of the inner wall of the folded portion.

[0009] Optionally, the cross-section of the sealing convex buckle is a structure with a convex structure, and the cross-section of the sealing concave buckle is a structure with a groove. The convex size of the sealing convex buckle is consistent with the groove size of the sealing concave buckle.

The sealing concave buckle is provided with a concave arc groove at the position corresponding to the lower group long tube and the lower group short tube. The inner wall sizes of the convex arc groove and the concave arc groove are consistent with the outer wall size of the lower group long tube.

[0010] Optionally, an elastic clip is fixedly connected to the edge of the convex arc-shaped groove, the elastic clip is elastic, and a lightweight groove is evenly formed on a side of the elastic clip away from the convex arc-shaped groove.

[0011] Optionally, an air inlet pipe is inserted into the top center of the humidification cup, the top of the air inlet pipe is fixedly connected to the bottom of the regulator, and the bottom of the air inlet pipe extends to the bottom of the inner wall of the humidification cup.

[0012] Optionally, the adjustment assembly includes a support bracket fixedly connected to the inner wall of the humidification cup, a pressing clip is fixedly connected to the opposite surface of the support bracket, an arc-shaped clip is symmetrically installed on the bottom of the pressing clip, the outer size of the arc-shaped clip is consistent with the inner wall size of the support bracket, a weakening groove is provided at the connection between the pressing clip and the support bracket, and a buffer spring is symmetrically installed on the inner wall of the support bracket, and the bottom of the buffer spring does not contact the inner wall of the support bracket.

[0013] Optionally, both ends of the support bracket are wide-mouthed, and a limiting sleeve is symmetrically installed on the bottom of the support bracket, and the inner wall size of the limiting sleeve is consistent with the outer wall size of the lower group long tube.

[0014] Optionally, the pressing clip, the supporting bracket and the limiting sleeve are an integrated manufacturing structure, and the whole is a curved elastic structure.

[0015] Optionally, a water inlet is fixedly connected to the top of the humidification cup, the water inlet is located above the folding portion, the bottom of the water inlet extends to the inside of the folding portion, and a drain pull ring is threadedly connected at the bottom center of the humidification cup.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects:

[0017] In the above scheme, by setting a water adding component and an adjusting component, both of which are arranged on the inner wall of the humidifier cup, the water adding component can not only improve the efficiency of regular water adding, but also can realize automatic water adding without opening the humidifier cup during the water adding process, thereby better ensuring that the water level of the humidifying liquid is maintained at the optimal state; the adjusting component can not only adjust the humidification processing volume of the humidifier cup, but also assist the humidifier cup in convenient water change. Compared with manually opening the humidifier cup to add or change water, this setting can automatically add water and conveniently change water, which reduces manual intervention, improves efficiency and reduces the risk of infection, and greatly improves the practicality of the oxygen humidifier.

[0018] By arranging the cooperation of the lower group long tube, the lower group short tube and the folding part, the lower group long tube and the lower group short tube are used to connect the folding part and the humidifying liquid inside the humidifying cup, and by changing the relative position relationship between the length of the lower group long tube and the lower group short tube and the liquid level, the siphon principle is used to achieve the purpose of automatic water addition, ensuring that the page of the humidifying liquid can always maintain the optimal water level height, so as to ensure that oxygen can fully absorb water when passing through the humidifying cup, achieve the ideal humidification effect, and effectively improve the use effect and safety of the humidifying cup.

[0019] By setting up a sealing convex buckle and a sealing concave buckle to cooperate with each other and utilizing the structural echo between the two, a sealing effect is achieved, and good sealing can be maintained after multiple uses. The separation and fitting sealing states of the sealing convex buckle and the sealing concave buckle are utilized to correspond to the large-volume and medium-volume usage states of the humidification cup to adapt to different usage scenarios. The sealing convex buckle and the sealing concave buckle are an integrated manufacturing structure with the humidification cup. This setting makes the processing technology of the three simpler during the production process, easier to produce, and reduces the manufacturer's capital investment.

[0020] By arranging the cooperation of the pressing clamp, the supporting frame and the arc clamp, water can be automatically added in two volume states, ensuring a variety of usage scenarios of the device. The bottom of the pressing clamp uses a drain pull ring to thin the connection position of the pressing clamp and the supporting frame. This arrangement makes it easier for the arc clamp to bend and deform from the position of the weakened groove under the action of external force, thereby pressing the arc clamp into the inside of the supporting frame. This structural arrangement makes the overall structure of the pressing clamp and the supporting frame elastic. Under the action of elasticity, the arc clamp can be displaced under the pressing action of external force, thereby realizing the interruption of the flow of the lower group long tube, the lower group short tube or the upper group long tube, the upper group short tube. The setting of the integrated structure of the pressing clamp and the supporting frame makes the overall structure simpler and more clever, and easy to produce and install and disassemble.

[0038] like Figures 1 to 8 As shown, an embodiment of the present invention provides an oxygen humidification device for respiratory function, including a regulator 1 and a humidification cup 2. The inner wall of the humidification cup 2 is fixedly connected to a water adding component, which is used to replenish water consumed during oxygen humidification treatment and is connected to the humidification cup 2; an adjustment component, which is used to assist in adjusting the humidification treatment volume of the humidification cup 2 and is connected to the humidification cup 2. The oxygen humidification device for respiratory function provided by the present invention is suitable for patients with airway humidification needs. In actual products, bubble humidification is achieved by introducing oxygen into the liquid (usually Sterile water for injection or distilled water) allows oxygen to pass through the sieve holes or bubbler to form tiny bubbles. As these bubbles rise in the liquid, the contact area and time between oxygen and water are increased, allowing oxygen to absorb moisture and achieve the purpose of humidification. The humidification cup 2 is usually marked with obvious maximum and minimum water level lines. During use, it is necessary to ensure that the humidification liquid level is between these two lines. By controlling the amount of humidification liquid, it is ensured that oxygen can fully absorb moisture when passing through the humidification cup 2. The bubble-type humidification method and working principle, as well as the definition principle of the water level line of the humidification cup 2, are disclosed in the prior art and therefore will not be described in detail.

[0039] By setting a water adding component and a regulating component, both of which are arranged on the inner wall of the humidifier cup 2, the water adding component can not only improve the efficiency of regular water adding, but also can realize automatic water adding without opening the humidifier cup 2 during the water adding process, thereby better ensuring that the water level of the humidifying liquid is maintained at the optimal state; the regulating component can not only adjust the humidification processing volume of the humidifier cup 2, but also assist the humidifier cup 2 to conveniently change water. Compared with manually opening the humidifier cup 2 to add or change water, this setting can automatically add water and conveniently change water, which reduces manual intervention, improves efficiency and reduces the risk of infection, and greatly improves the practicality of the oxygen humidifier.

[0040] like Figures 1 to 8 As shown, the water adding assembly includes a folding portion 10 arranged at the top of the humidifying cup 2, a lower group long tube 11 and a lower group short tube 12 are inserted on one side of the folding portion 10, and an upper group long tube 13 and an upper group short tube 14 are inserted on the other side of the folding portion 10, and a sealing convex buckle 5 and a sealing concave buckle 6 are fixedly connected in the middle of the inner wall of the humidifying cup 2, the sealing convex buckle 5 and the sealing concave buckle 6 are arranged opposite to each other, the lower group long tube 11 and the lower group short tube 12 extend to the bottom of the inner wall of the humidifying cup 2, the upper group long tube 13 and the upper group short tube 14 extend to above the sealing convex buckle 5 and the sealing concave buckle 6, the lower group long tube 11, the lower group short tube 12, the upper group long tube 13 and the upper group short tube 14 are all made of polyvinyl chloride (PVC) with the same pipe diameter size, and all extend to the bottom of the inner wall of the folding portion 10, the cross section of the sealing convex buckle 5 is a convex structure, the cross section of the sealing concave buckle 6 is a groove structure, and the convex size of the sealing convex buckle 5 is the same as the concave size of the sealing concave buckle 6 The groove sizes are consistent, and the sealing convex buckle 5 is provided with a convex arc groove 7 at the position corresponding to the lower group long tube 11 and the lower group short tube 12, and the sealing concave buckle 6 is provided with a concave arc groove 9 at the position corresponding to the lower group long tube 11 and the lower group short tube 12. The inner wall sizes of the convex arc groove 7 and the concave arc groove 9 are consistent with the outer wall size of the lower group long tube 11. An elastic clip 8 is fixedly connected to the edge of the convex arc groove 7. The elastic clip 8 is elastic, and lightweight grooves are evenly provided on the side of the elastic clip 8 away from the convex arc groove 7. An air inlet pipe 3 is inserted at the top center of the humidification cup 2, and the top of the air inlet pipe 3 is fixedly connected to the bottom of the regulator 1, and the bottom of the air inlet pipe 3 extends to the bottom of the inner wall of the humidification cup 2. The top of the humidification cup 2 is fixedly connected to the water inlet 4, and the water inlet 4 is located above the folding part 10. The bottom of the water inlet 4 extends to the inside of the folding part 10, and the bottom center of the humidification cup 2 is threaded with a drain pull ring 21.

[0041] Specifically, the humidification cup 2 is made of soft transparent silicone material as a whole. The transparent material property makes it easy to observe the relationship between the humidification liquid and the water level inside the humidification cup 2, so as to facilitate automatic water addition. Moreover, the soft silicone material itself has good flexibility and elasticity, which can realize the folding function. A folding portion 10 is provided on the top of the humidification cup 2. The cross section of the folding portion 10 is a U-shaped structure. The U-shaped feature makes it easy to use the folding portion 10 to store the humidification liquid, so as to facilitate water addition. The folding portion 10 uses the cup body to adopt a folding ring design. These structures enable the cup body to fold under pressure. Without being damaged, the folding ring enables the cup body to be folded along a specific position for easy operation, and the elastic restoring force of the material is utilized so that the humidification cup 2 can be quickly restored to the use state when unfolded; in addition, the bottom of the air inlet pipe 3 can be extended and retracted up and down, and can hover at a required height. The extension and hovering principles of the air inlet pipe 3 are disclosed as prior art and will not be elaborated on here. Similarly, the soft silicone material of the humidification cup 2 itself has good flexibility and elasticity. When the length of the air inlet pipe 3 needs to be adjusted, the bottom of the air inlet pipe 3 is pinched by hand to stretch it to adjust the required length of the air inlet pipe 3.

[0042] Two sets of catheters are inserted into the interior of the humidification cup 2, and a lower set of water level lines and an upper set of water level lines are set on the outer wall of the humidification cup 2. Each set of water level lines is provided with a minimum water level line and a maximum water level line. Each set of catheters is provided with one long and one short. The first set of catheters includes a lower long tube 11 and a lower short tube 12, and the second set of catheters includes an upper long tube 13 and an upper short tube 14. Both sets of catheters are made of soft silicone transparent material, which is convenient for observing the liquid situation in the tube and can be bent easily. In order to adapt to the U-shaped structural characteristics of the folding portion 10, the lower long tube 11 extends to the bottom of the humidification cup 2, and cooperates with the lower short tube 12 to extend above the lowest water level of the lower water level line. By using the siphon principle, when the liquid level of the humidification liquid is between the lowest water level line and the highest water level line of the lower water level line, the liquid level inside the folding portion 10 is kept higher than the bottom of the lower long tube 11 and the lower short tube 12. At this time, both ends of the lower long tube 11 and the lower short tube 12 are in the humidification liquid. When the liquid level of the humidifying liquid is lower than the bottom of the lower short tube 12, the lower short tube 12 will suck the humidifying liquid inside the folded part 10 and replenish it into the humidifying cup 2 until the liquid level of the humidifying liquid in the humidifying cup 2 is higher than the bottom of the lower short tube 12 again, thereby achieving the purpose of automatic water addition. The phenomenon of the siphon principle and its working principle are disclosed as prior art and therefore will not be described in detail. By arranging the lower long tube 11, the lower short tube 12 and the folded part 10 to cooperate, the lower long tube 11 and the lower short tube 12 are used to connect the folded part 10 and the humidifying liquid inside the humidifying cup 2, and the relative position relationship between the length of the lower long tube 11 and the lower short tube 12 and the liquid level changes, the siphon principle is used to achieve the purpose of automatic water addition, ensuring that the page of the humidifying liquid can always maintain the optimal water level, so as to ensure that the oxygen can fully absorb water when passing through the humidifying cup 2, achieve the ideal humidifying effect, and effectively improve the use effect and safety of the humidifying cup 2.

[0043] The sealing convex buckle 5 and the sealing concave buckle 6 provided inside the humidifying cup 2 cooperate with each other. The sealing convex buckle 5 and the sealing concave buckle 6 are made of the same material as the humidifying cup 2 and are an integral manufacturing structure with the humidifying cup 2. The sealing convex buckle 5 and the sealing concave buckle 6 are respectively provided on the opposite inner side surfaces of the inner wall of the humidifying cup 2, and are sealed by mutual engagement. When the sealing convex buckle 5 and the sealing concave buckle 6 are engaged with each other, the oppositely distributed sealing convex buckles 5 and the sealing concave buckles 6 are engaged with each other, that is, the two ends of the sealing convex buckle 5 correspond one-to-one with the two ends close to the sealing concave buckle 6, so as to realize the folded and closed state of the humidifying cup 2 and achieve the effect of preventing liquid from leaking. The sealing structure and working principle of using silicone material and the sealing convex buckle 5 and the sealing concave buckle 6 to achieve sealing and preventing liquid from leaking are disclosed as prior art and will not be elaborated on here. By utilizing the elastic deformation of the material, when pressure is applied, the sealing convex buckle 5 and the sealing concave buckle 6 fit tightly together to form a seal; when the pressure is released, the material returns to its original shape, which is convenient for reopening. Since the lower group long tube 11 and the lower group short tube 12 pass through the sealing convex buckle 5 and the sealing concave buckle 6, the folded closed state of the humidification cup 2 is blocked to a certain extent. Therefore, the convex arc groove 7 and the concave arc groove 9 are respectively provided at the positions of the sealing convex buckle 5 and the sealing concave buckle 6 corresponding to the lower group long tube 11 and the lower group short tube 12 for avoidance. In order to ensure the integrity In order to improve the sealing effect of the body, an elastic clip 8 is fixedly connected to the convex arc groove 7, which is convenient for using the elastic clip 8 to squeeze the lower group long tube 11 and the lower group short tube 12 when sealing. The elastic clip 8 is used to clamp and limit the lower group long tube 11 and the lower group short tube 12 when the sealing convex buckle 5 and the sealing concave buckle 6 are engaged with each other, ensuring that the lower group long tube 11 and the lower group short tube 12 are completely clamped, and there will be no liquid leakage here to affect the overall sealing, thereby maximizing the sealing effect and meeting the switching of usage scenarios.

[0044] After the old humidifying liquid has been drained out, close the drain ring 21, open the sealing convex buckle 5 and the sealing concave buckle 6, and pinch the lower group long tube 11 and the lower group short tube 12 between the sealing convex buckle 5 and the sealing concave buckle 6. The humidifying cup 2 is convenient to be moved, so as to facilitate the expansion of the sealing convex buckle 5 and the sealing concave buckle 6. After observing that the new humidifying liquid is at the appropriate water level, the water inlet 4 is closed and then the oxygen source is slowly opened to check whether the oxygen flows out smoothly and whether there are bubbles in the humidifying cup 2 to confirm that the humidification effect is good. The whole water changing process is not only simple to operate and improves efficiency, but also the whole water changing process can be completed without unscrewing the humidifying cup 2, which effectively reduces the risk of infection, improves the humidification effect, and ensures the safety and comfort of the patient's treatment. By setting the sealing convex buckle 5 and the sealing concave buckle 6 to cooperate, the structural echo between the two is utilized to achieve a sealing effect, and good sealing can still be maintained after multiple uses. The sealing convex buckle 5 and the sealing concave buckle 6 are an integrated manufacturing structure with the humidifying cup 2. Such a setting makes the processing technology of the three simpler and easier to be manufactured during the production process, thereby reducing the manufacturer's capital investment.

[0045] like Figures 3 and 4 and Figures 7 and 8 As shown, the adjustment assembly includes a support bracket 16 fixedly connected to the inner wall of the humidification cup 2, and a pressing clip 15 is fixedly connected to the opposite surface of the support bracket 16, and an arc clip 19 is symmetrically installed on the bottom of the pressing clip 15. The outer size of the arc clip 19 coincides with the inner wall size of the support bracket 16, and a weakening groove 20 is provided at the connection between the pressing clip 15 and the support bracket 16. Buffer springs 17 are symmetrically installed on the inner wall of the support bracket 16, and the bottom of the buffer springs 17 does not contact the inner wall of the support bracket 16. Both ends of the support bracket 16 are wide-mouthed, and a limiting sleeve 18 is symmetrically installed on the bottom of the support bracket 16. The inner wall size of the limiting sleeve 18 coincides with the outer wall size of the lower group long tube 11. The pressing clip 15, the support bracket 16 and the limiting sleeve 18 are an integrated manufacturing structure, and the whole is a curved elastic structure.

[0046] Specifically, the purpose of the support bracket 16 is to fix the lower group long tube 11, the lower group short tube 12 and the upper group long tube 13, the upper group short tube 14 and the humidification cup 2, and use the limiting sleeve 18 to bend the lower group long tube 11, the lower group short tube 12 and the upper group long tube 13, the upper group short tube 14 into an arc that matches the shape of the folding portion 10 of the humidification cup 2, and use the buffer spring 17 to clamp the lower group long tube 11, the lower group short tube 12 and the upper group long tube 13, the upper group short tube 14 inside the support bracket 16 to facilitate automatic water addition. When the pressing clamp 15 is pressed, the weakened groove 20 facilitates the pressing of the arc clamp 19 to the inside of the support bracket 16, and then the arc clamp 19 cooperates with the structure of the support bracket 16 to achieve locking of the lower group long tube 11, the lower group short tube 12 or the upper group long tube 13, the upper group short tube 14.

[0047] When the humidification cup 2 is used as a large volume, the sealing convex buckle 5 and the sealing concave buckle 6 are in a separated state. The pressing clamp 15 is pressed downward to clamp the upper group long tube 13 and the upper group short tube 14 between the support bracket 16 and the arc clamp 19, so as to cut off the flow of the upper group long tube 13 and the upper group short tube 14 without affecting the use of the lower group long tube 11 and the lower group short tube 12. Similarly, when the humidification cup 2 is used as a medium volume, the sealing convex buckle 5 and the sealing concave buckle 6 are in a fitted and sealed state. The pressing clamp 15 is pressed downward to clamp the lower group long tube 11 and the lower group short tube 12 between the support bracket 16 and the arc clamp 19, so as to cut off the flow of the lower group long tube 11 and the lower group short tube 12 without affecting the use of the upper group long tube 13 and the upper group short tube 14.

[0048] When the humidification cup 2 is used as a medium volume, the upper group long tube 13 and the upper group short tube 14 cooperate with the folding part 10 to realize the working principle of automatic water addition, which is consistent with the automatic water addition working principle of the lower group long tube 11 and the lower group short tube 12 mentioned above. By using the siphon principle, when the liquid level of the humidification liquid is between the lowest water level line and the highest water level line of the upper group water level line, the liquid level inside the folding part 10 is kept higher than the bottom of the upper group long tube 13 and the upper group short tube 14. At this time, both ends of the upper group long tube 13 and the upper group short tube 14 are in the humidification liquid. Once the liquid level of the humidification liquid is lower than the bottom of the upper group short tube 14, the upper group short tube 14 will absorb the humidification liquid inside the folding part 10 to replenish it into the humidification cup 2 until the liquid level of the humidification liquid in the humidification cup 2 is higher than the bottom of the upper group short tube 14 again, thereby achieving the purpose of automatic water addition.

[0049] By arranging the cooperation of the pressing clamp 15, the supporting frame 16 and the arc clamp 19, water can be automatically added in two volume states, ensuring a variety of usage scenarios of the device. The bottom of the pressing clamp 15 uses a water drain pull ring 21 to thin the connection position of the pressing clamp 15 and the supporting frame 16. This arrangement makes it easier for the arc clamp 19 to bend and deform from the position of the weakened groove 20 under the action of external force, thereby pressing the arc clamp 19 into the inside of the supporting frame 16. This structural arrangement makes the overall structure of the pressing clamp 15 and the supporting frame 16 elastic. Under the action of elasticity, the arc clamp 19 can be displaced under the pressing action of external force, thereby realizing the interruption of flow to the lower group long tube 11, the lower group short tube 12 or the upper group long tube 13, the upper group short tube 14. The setting of the integrated structure of the pressing clamp 15 and the supporting frame 16 makes the overall structure simpler and more clever, and easy to produce and install and disassemble.

[0050] The workflow of the technical solution provided by the present invention is as follows:

[0051] When water needs to be changed, first use the regulator 1 to turn off the oxygen source to ensure safety, pull the bottom of the humidification cup 2 by hand and stretch it downward so that the folding part 10 is stretched, and the humidification liquid in the folding part 10 is retained in the interior of the humidification cup 2, and then open the drain ring 21 to let the old humidification liquid flow into the designated container to avoid polluting the environment. At the same time, when the humidification liquid is observed to be lower than the sealing convex buckle 5 and the sealing concave buckle 6, the sealing convex buckle 5 and the sealing concave buckle 6 are matched to seal, and after sealing, push it upward to restore the folding part 10 to its original state, and then open the water inlet 4 to let new humidification liquid The liquid flows into the humidifying cup 2 through the water inlet 4, and the old humidifying liquid is discharged and the new humidifying liquid is added at the same time. After the old humidifying liquid has flowed out, close the drain ring 21, and then open the sealing convex buckle 5 and the sealing concave buckle 6. Pinch the lower group long tube 11 and the lower group short tube 12 by hand and move them between the sealing convex buckle 5 and the sealing concave buckle 6 to facilitate the expansion of the sealing convex buckle 5 and the sealing concave buckle 6. After observing that the new humidifying liquid is at the appropriate water level, close the water inlet 4 and then slowly open the oxygen source to check whether the oxygen flows out smoothly and whether there are bubbles in the humidifying cup 2 to confirm that the humidifying effect is good.

[0052] Two groups of catheters are inserted into the interior of the humidifying cup 2, and a lower group of water level lines and an upper group of water level lines are set on the outer wall of the humidifying cup 2. Each group of water level lines is provided with a minimum water level line and a maximum water level line. Each group of catheters is provided with one long and one short. The first group of catheters includes a lower group of long tubes 11 and a lower group of short tubes 12, and the second group of catheters includes an upper group of long tubes 13 and an upper group of short tubes 14. Both groups of catheters are made of soft silicone transparent material, which is convenient for observing the liquid situation in the tubes and can be bent to adapt to the U-shaped structural characteristics of the folding portion 10. The lower group of long tubes 11 extends to the bottom of the humidifying cup 2, and cooperates with the lower group of short tubes 12 to extend to Above the lowest water level line of the lower group of water levels, by utilizing the siphon principle, when the liquid level of the humidifying liquid is between the lowest water level line and the highest water level line of the lower group of water levels, the liquid level inside the folded portion 10 is kept higher than the bottom of the lower group of long tubes 11 and the lower group of short tubes 12. At this time, both ends of the lower group of long tubes 11 and the lower group of short tubes 12 are in the humidifying liquid. Once the liquid level of the humidifying liquid is lower than the bottom of the lower group of short tubes 12, the lower group of short tubes 12 will absorb the humidifying liquid inside the folded portion 10 and replenish it into the humidifying cup 2 until the liquid level of the humidifying liquid in the humidifying cup 2 is higher than the bottom of the lower group of short tubes 12 again, thereby achieving the purpose of automatic water addition.

[0053] When the humidification cup 2 is used as a large volume, the sealing convex buckle 5 and the sealing concave buckle 6 are in a separated state, and the pressing clamp 15 is pressed downward to clamp the upper group long tube 13 and the upper group short tube 14 between the support bracket 16 and the arc clamp 19, so as to cut off the flow of the upper group long tube 13 and the upper group short tube 14 without affecting the use of the lower group long tube 11 and the lower group short tube 12. Similarly, when the humidification cup 2 is used as a medium volume, the sealing convex buckle 5 and the sealing concave buckle 6 are in a fitted and sealed state, and the pressing clamp 15 is pressed downward to clamp the lower group long tube 11 and the lower group short tube 12 between the support bracket 16 and the arc clamp 19 , to cut off the flow of the lower group long tube 11 and the lower group short tube 12 so as not to affect the use of the upper group long tube 13 and the upper group short tube 14. This device can not only improve the efficiency of regular water addition, but also can automatically add water without opening the humidification cup 2 during the water addition process, thereby better ensuring that the water level of the humidification liquid is maintained in an optimal state. It can also adjust the humidification processing volume of the humidification cup 2, and assist the humidification cup 2 to facilitate water change. This automatic water addition and convenient water change method reduces manual intervention, improves efficiency, and also reduces the risk of infection, greatly improving the practicality of the oxygen humidification device.
