Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and more specifically, to an improved oxygen inhalation tube. Background Technology

[0002] Oxygen therapy is a commonly used clinical treatment method and a part of oxygen therapy. It is a way to relieve hypoxia, increase arterial blood oxygen partial pressure and oxygen saturation, promote metabolism, and is one of the important methods for adjuvant treatment of various diseases. Currently, after a patient finishes receiving oxygen, the nasal cannula is often left hanging haphazardly at the head of the bed or on the oxygen flow meter, which easily leads to bacterial growth. Leaving it hanging haphazardly at the head of the bed or on the oxygen flow meter also makes it easy for one end of the nasal cannula to fall to the ground, causing contamination and bacterial infection. Furthermore, if the nasal cannula is placed in a plastic bag when oxygen therapy is stopped, timely cleaning is not possible.

[0003] Currently, there are many methods used in clinical practice to protect oxygen tubing from contamination. For example, non-woven fabric bags are used, and the entire oxygen tubing is placed inside the bag when in use. However, since the oxygen tubing itself is exposed to the air, it may still be contaminated when mixed with nasal plugs in the non-woven fabric bag. Other methods include using infusion set packaging bags, disposable plastic bags, or even disposable shoe covers to protect the oxygen tubing. These packaging bags are made from a variety of materials and do not meet the hospital's infection control requirements.

[0004] Therefore, providing an improved oxygen tubing to protect the nasal cannula and prevent contamination of the oxygen tubing and nasal cannula is a technical problem that urgently needs to be solved in this field. Utility Model Content

[0005] In view of this, the present invention provides an improved oxygen inhalation tube, which facilitates the protection of the nasal cannula oxygen inhalation head and prevents the oxygen inhalation tube and nasal cannula oxygen inhalation head from being contaminated.

[0006] This application also provides an improved oxygen inhalation tube, comprising: an oxygen inhalation tube including an oxygen inhalation main tube and two oxygen inhalation branch tubes, a connection portion connecting the oxygen inhalation main tube and the two oxygen inhalation branch tubes, and a nasal plug-type oxygen inhalation head connecting the two oxygen inhalation branch tubes; further comprising: a storage box slidably connected to the oxygen inhalation tube, wherein a retaining ring structure is fixed on one side wall of the storage box, and the retaining ring structure is slidably connected to the oxygen inhalation branch tubes;

[0007] The storage box includes a box body and a lid that covers the box body; a first storage slot is provided inside the box body, and a storage device adapted to the nasal plug oxygen inhalation head is placed in the first storage slot; a channel for the oxygen inhalation tube to pass through is provided on the storage box, and a sealing device is provided on the storage box for switching the open and closed states of the channel.

[0008] Optionally, the retaining ring structure is detachably connected to the oxygen inhalation branch tube.

[0009] Optionally, the box body and the box lid are hinged; a groove is provided on the top surface of the box body, and a protrusion adapted to the groove is provided on the box lid.

[0010] Optionally, the channel includes a first through slot penetrating the housing and a second through slot penetrating the protrusion.

[0011] Optionally, the box body is provided with a movable groove, and the sealing device is fixed in the movable groove.

[0012] Optionally, the sealing device includes a sealing structure and a return spring, one end of which is connected to the bottom of the sealing structure and the other end is fixed to the bottom of the movable groove.

[0013] Optionally, the sealing device further includes a limiting member, which is used to limit the movement distance of the sealing structure. A limiting hole is provided on the inner wall of the box, and the limiting member moves within the limiting hole.

[0014] Optionally, the sealing device includes a sealing body and a sealing plate adapted to the second through groove.

[0015] Optionally, a second storage slot is provided inside the box.

[0016] Optionally, a hook is attached to the lid.

[0017] Compared with the prior art, the improved oxygen inhalation tube provided by this utility model achieves at least the following beneficial effects:

[0018] This invention provides an improved oxygen tubing with a snap-ring structure that allows for detachable connection to the oxygen branch tube and slides up and down along it. It is easy to use; simply open the storage box and push or pull it to place the nasal cannula head inside. Closing the lid completes the storage of the nasal cannula head, preventing dust and contamination. The protrusion on the lid engages with the groove in the box body, preventing dust and bacteria from entering the box through the gap between the lid (without protrusions) and the box body (without grooves), thus preventing contamination of the cleaned and disinfected oxygen tubing. The storage container and the nasal cannula head are fitted together to achieve a seal. The seal between the lid's protrusion and the box body's groove, combined with the storage container's seal, provides a double seal, effectively preventing dust entry and external contamination. A sealing device is used to switch the channel between open and closed states, preventing external contamination from entering the box. This invention can also be used in conjunction with oxygen tubing storage bags to store the entire oxygen tubing, preventing cross-infection between the nasal cannula head and other parts of the tubing.

[0019] Of course, any product implementing this utility model does not necessarily need to achieve all the technical effects described above at the same time.

Detailed Implementation

[0032] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present invention.

[0033] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0034] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0035] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0036] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0037] In one alternative embodiment, refer to Figures 1-3The improved oxygen inhalation tube provided in this embodiment includes an oxygen inhalation tube comprising a main oxygen inhalation tube 10 and two branch oxygen inhalation tubes 11, a connecting portion 12 connecting the main oxygen inhalation tube 10 and the two branch oxygen inhalation tubes 11, and a nasal plug-type oxygen inhalation head 13 connecting the two branch oxygen inhalation tubes 11; it also includes a storage box 20 slidably connected to the oxygen inhalation tube, a retaining ring structure 23 fixed on one side wall of the storage box 20, the retaining ring structure 23 being detachably connected to the branch oxygen inhalation tubes 11, and the retaining ring structure 23 being slidably connected to the branch oxygen inhalation tubes 11; the storage box 20 includes a box body 21 and a box lid 22 covering the box body 21. The box body 21 is hinged to the box cover 22. A groove 26 is provided on the top surface of the box body 21, and a protrusion 27 adapted to the groove 26 is provided on the box cover 22. A first storage slot 24 is provided inside the box body 21, and a storage device 25 adapted to the nasal plug oxygen inhalation head 13 is placed in the first storage slot 24. The storage box 20 is provided with a channel 30 for the oxygen inhalation tube 11 to pass through. The channel 30 includes a first through groove 31 that penetrates the box body 21 and a second through groove 32 that penetrates the protrusion 27. The storage box 20 is provided with a sealing device 40, which is used to switch the open and closed states of the channel 30.

[0038] Understandably, the retaining ring structure 23 fixed on one side wall of the storage box 20 is detachably connected to the oxygen inhalation tube 11. The retaining ring structure 23 can slide up and down on the oxygen inhalation tube 11. When the patient uses the oxygen inhalation tube, the storage box 20 is located above the connecting part 12 and is slidably connected to the two oxygen inhalation tubes 11. The storage box 20 is placed on the oxygen inhalation tube 11 in a position that does not affect the patient's oxygen inhalation. It should be noted that the fixed position of the retaining ring structure 23 is mainly to avoid affecting the placement of the oxygen inhalation tube in the storage box 20. When the patient no longer needs oxygen after inhalation, clean and disinfect the oxygen tubing, then push the storage box 20 along the direction from the oxygen branch tube 11 to the nasal cannula oxygen head 13. When the patient is near the nasal cannula oxygen head 13, open the box cover 22 and continue pushing the storage box 20. Use the sealing device 40 to switch the channel 30 from the closed state to the open state. Place the nasal cannula oxygen head 13 into the suitable storage container 25. The portion of the oxygen branch tube 11 connecting to the nasal cannula oxygen head 13 is respectively locked in the storage container 25 and the first through groove 31 of the box body 21. Close the box cover 22. The protrusion 27 of the box cover 22 is engaged with the groove 26 of the box body 21. The second through groove 32 passing through the protrusion 27 is connected to the first through groove 31 of the box body 21 to form the channel 30. The channel 30 is adapted to the oxygen branch tube 11 to prevent dust from entering the box body 21 from the gap between the channel 30 and the oxygen branch tube 11. Complete the storage of the nasal cannula oxygen head 13. After storing the nasal cannula oxygen head 13, clean and disinfect the oxygen tubing and place it in a storage bag to prevent cross-infection between the nasal cannula oxygen head 13 and other parts of the oxygen tubing.

[0039] It should be noted that the retaining ring structure 23 has a certain degree of elasticity. During use, the space at the opening of the retaining ring structure 23 is widened. When the oxygen inhalation tube 11 is inserted into the retaining ring structure 23, the tension applied to the retaining ring structure 23 is released, allowing the retaining ring structure 23 to hold the oxygen inhalation tube 11 in place, preventing it from detaching. This connects the storage box 20 to the oxygen inhalation tube. The inner wall of the retaining ring structure 23 and the outer wall of the oxygen inhalation tube 11 have a clearance fit, allowing the retaining ring structure 23 to slide up and down along the oxygen inhalation tube 11 for easy movement. The storage box 20 is connected to the oxygen inhalation tube. When oxygen inhalation is not needed, the storage box 20 is simply pushed to the nasal cannula oxygen head 13, and the nasal cannula oxygen head 13 is placed inside the storage box 20 to protect it from dust and prevent contamination.

[0040] The protrusion 27 of the lid 22 engages with the groove 26 of the body 21, preventing dust and bacteria from entering the body 21 through the gap between the lid 22 (without the protrusion 27) and the body 21 (without the groove 26), thus contaminating the cleaned and disinfected oxygen tubing. To ensure a tight fit between the lid 22 and the body 21 and prevent the lid 22 from detaching, a snap-fit ​​structure 46 can also be used. Different types and sizes of nasal cannula oxygen heads 13 require different compatible storage containers 25. When storing different types and sizes of nasal cannula oxygen heads 13, such as single nasal cannula oxygen heads 13 or detachable nasal cannula oxygen heads 13, a compatible storage container 25 can be used instead of a new storage box 20, saving resources and production costs. The storage container 25 can be made of soft silicone material to fit snugly against the single nasal cannula oxygen head 13. For example, this silicone material has a certain degree of elasticity. When the receiver 25 is attached to the nasal cannula oxygen head 13, the silicone will slightly deform to fill the gaps around the connector, achieving a good sealing effect. The double seal achieved by the interlocking of the protrusion 27 of the lid 22 with the groove 26 of the body 21 and the seal of the receiver 25 effectively prevents dust from entering and external contamination from entering.

[0041] When using the storage box 20, the channel 30 is switched from a closed state to an open state using the sealing device 40 to facilitate the placement of the oxygen inhalation tube 11 when placing the nasal plug oxygen inhalation head 13. When not using the storage box 20, the channel 30 is switched from an open state to a closed state using the sealing device 40 to prevent dust from entering and external contamination.

[0042] by Figure 1 For reference, the first direction X is the horizontal direction from the first storage slot 24 to the second storage slot 29; the second direction Y is the horizontal direction from the right sealing device 40 to the left first through slot 31; and the third direction Z is the direction in which the opening of the box 21 is vertically upward. The first direction X, the second direction Y, and the third direction Z intersect each other perpendicularly.

[0043] In order to enable the sealing device 40 to switch the open and closed states of channel 30, in an optional embodiment, refer to Figures 3-9 The box body 21 has a movable groove 28, and a sealing device 40 is fixed inside the movable groove 28. The sealing device 40 includes a sealing structure 41, a return spring 44, and a limiting member 47. One end of the return spring 44 is connected to the bottom of the sealing structure 41, and the other end is fixed to the bottom of the movable groove 28. The limiting member 47 is used to limit the movement distance of the sealing structure 41. A limiting hole 48 is provided on the inner wall of the box body 21, and the limiting member 47 moves within the limiting hole 48. Specifically, the sealing device 40 includes a sealing body 42 and a sealing plate 43 adapted to the second through groove 32.

[0044] It is understood that the movable groove 28 connects to the recess 26, and the closing structure 41 moves up and down within the space formed by the movable groove 28, the overlapping space of the recess 26 above the movable groove 28 and the first through groove 31, and the second through groove 32, thereby closing and opening the channel 30 formed by the first through groove 31 and the second through groove 32. Specifically, the length of the movable groove 28 in the first direction X is greater than the length of the first through groove 31 in the first direction X, and the length of the movable groove 28 in the second direction Y is equal to the length of the recess 26 in the second direction Y. The movable groove 28 is located below the recess 26 and connects to the recess 26.

[0045] Combination Figures 3-6 When the lid 22 and the body 21 are open, the return spring 44 is in its natural state, and the closing structure 41 completely closes the first through slot 31. Specifically, the closing body 42 completely closes the first through slot 31, and the closing plate 43 extends beyond the top surface of the body 21. At this time, the limiting member 47 does not limit the movement distance of the closing structure 41.

[0046] Combination Figure 9When the lid 22 and the body 21 are closed, the sealing structure 41 moves downward, the return spring 44 is compressed and moves downward, and the second through groove 32 penetrating the protrusion 27 and the first through groove 31 of the body 21 are joined to form a channel 30. The part of the protrusion 27 adjacent to the second through groove 32, the sealing plate 43 and the part of the sealing body 42 seal the channel 30 and the first through groove 31. Because the sealing plate 43 is subjected to the upward elastic force of the return spring 44 and the downward pressure of the lid 22, the outer edge of the sealing plate 43 is tightly fitted with the outer wall of the second through groove 32 on the protrusion 27, preventing dust from entering the body 21 from the gap between the sealing plate 43 and the second through groove 32. It should be noted that when the nasal plug oxygen head 13 is detachable, the nasal plug oxygen head 13 is directly placed into the body 21 without using the limiting member 47 to limit the sealing structure 41, and the lid 22 and the body 21 are closed to store the nasal plug oxygen head 13. To prevent dust from entering the box 21 through the gap between the sealing plate 43 and the second through groove 32, other dustproof designs can be implemented on the part of the sealing plate 43 that contacts the second through groove 32.

[0047] Combination Figures 7-8 The limiting hole 48 is formed on the right inner wall of the box 21 in the opposite direction of the second direction Y. The limiting hole 48 penetrates the inner wall of the box 21 in the second direction Y until it enters the inner wall of the box 21 in the opposite direction of the second direction Y. The limiting hole 48 formed on the left inner wall of the box 21 is similar in structure to the limiting hole 48 formed on the right inner wall of the box 21 in the opposite direction, and will not be described in detail.

[0048] When the lid 22 and body 21 are closed and an oxygen tube is placed inside, the sealing structure 41 is compressed below the groove 26, and the limiting member 47 is inserted through the limiting hole 48 on the inner wall of the body 21. The limiting member 47 prevents the sealing body 42 from moving upward along the third direction Z. The protrusion 27 adjacent to the second through groove 32 and the oxygen branch tube 11 seal the channel 30 and the first through groove 31, preventing dust from entering the body 21 from the gap between the oxygen branch tube 11 and the first through groove 31 and the second through groove 32.

[0049] By switching the open and closed states of the channel 30 through the sealing device 40, the closed state of the storage box 20 when it is not in use and the closed state of the storage box 20 when it is used to store the oxygen inhalation tube will not cause dust from outside the channel 30 to contaminate the inside of the storage box 20 due to the opening of the channel 30.

[0050] In one alternative embodiment, refer to Figure 1 , Figure 9 The box body 21 has a second storage slot 29 inside. The lid 22 is connected to a hook 45.

[0051] Understandably, wiping reusable oxygen tubing after use is a crucial step in the cleaning process. After oxygen therapy, residual moisture and secretions from the patient's exhaled breath may remain. Timely wiping prevents these substances from drying and accumulating on the tubing, facilitating subsequent cleaning and disinfection. The second storage slot 29 within the housing 21 can hold disposable medical cotton balls and other cleaning supplies, making it convenient to wipe the oxygen tubing clean and avoiding prolonged searching for cleaning supplies, which could cause the patient's exhaled moisture and secretions to dry. When hanging the oxygen tubing, it can be suspended using the hook 45 on the lid 22. This prevents the oxygen tubing from falling off due to the weight of the housing 21 shifting the center of gravity when directly suspended. It should be noted that the hook 45 is movable. When not in use, the hook 45 is flush with the top surface of the lid 22; when in use, the hook 45 forms an angle with the top surface of the lid 22 and is no longer flush.

[0052] The snap ring structure 23 of this utility model is detachably connected to the oxygen inhalation tube 11 and can slide up and down on the oxygen inhalation tube 11, making it convenient to use. Simply open the storage box 20 and push or pull it to place the nasal plug oxygen inhalation head 13 into the storage box 20. Closing the box lid 22 completes the storage of the nasal plug oxygen inhalation head 13, preventing dust and contamination. The sealing device 40 is used to switch the open and closed states of the channel 30. The storage unit 25 fits snugly against the nasal plug oxygen inhalation head 13 to achieve a seal. The protrusion 27 of the box lid 22 engages with the groove 26 of the box body 21 for a dustproof seal. The sealing of the storage unit 25 and the sealing device 40 seal the channel 30, providing multiple seals that effectively prevent dust from entering and avoid external contamination from contaminating the inside of the box body 21 through the channel 30. This utility model can also be used in conjunction with oxygen tube storage bags to store the entire oxygen tube and prevent cross-contamination. In an optional embodiment, refer to... Figures 1-3The improved oxygen inhalation tube provided in this embodiment includes an oxygen inhalation tube comprising a main oxygen inhalation tube 10 and two branch oxygen inhalation tubes 11, a connecting portion 12 connecting the main oxygen inhalation tube 10 and the two branch oxygen inhalation tubes 11, and a nasal plug-type oxygen inhalation head 13 connecting the two branch oxygen inhalation tubes 11; it also includes a storage box 20 slidably connected to the oxygen inhalation tube, a retaining ring structure 23 fixed on one side wall of the storage box 20, the retaining ring structure 23 being detachably connected to the branch oxygen inhalation tubes 11, and the retaining ring structure 23 being slidably connected to the branch oxygen inhalation tubes 11; the storage box 20 includes a box body 21 and a box lid 22 covering the box body 21. The box body 21 is hinged to the box cover 22. A groove 26 is provided on the top surface of the box body 21, and a protrusion 27 adapted to the groove 26 is provided on the box cover 22. A first storage slot 24 is provided inside the box body 21, and a storage device 25 adapted to the nasal plug oxygen inhalation head 13 is placed in the first storage slot 24. The storage box 20 is provided with a channel 30 for the oxygen inhalation tube 11 to pass through. The channel 30 includes a first through groove 31 that penetrates the box body 21 and a second through groove 32 that penetrates the protrusion 27. The storage box 20 is provided with a sealing device 40, which is used to switch the open and closed states of the channel 30.

[0053] Understandably, the retaining ring structure 23 fixed on one side wall of the storage box 20 is detachably connected to the oxygen inhalation tube 11. The retaining ring structure 23 can slide up and down on the oxygen inhalation tube 11. When the patient uses the oxygen inhalation tube, the storage box 20 is located above the connecting part 12 and is slidably connected to the two oxygen inhalation tubes 11. The storage box 20 is placed on the oxygen inhalation tube 11 in a position that does not affect the patient's oxygen inhalation. It should be noted that the fixed position of the retaining ring structure 23 is mainly to avoid affecting the placement of the oxygen inhalation tube in the storage box 20. When the patient no longer needs oxygen after inhalation, clean and disinfect the oxygen tubing, then push the storage box 20 along the direction from the oxygen branch tube 11 to the nasal cannula oxygen head 13. When the patient is near the nasal cannula oxygen head 13, open the box cover 22 and continue pushing the storage box 20. Use the sealing device 40 to switch the channel 30 from the closed state to the open state. Place the nasal cannula oxygen head 13 into the suitable storage container 25. The portion of the oxygen branch tube 11 connecting to the nasal cannula oxygen head 13 is respectively locked in the storage container 25 and the first through groove 31 of the box body 21. Close the box cover 22. The protrusion 27 of the box cover 22 is engaged with the groove 26 of the box body 21. The second through groove 32 passing through the protrusion 27 is connected to the first through groove 31 of the box body 21 to form the channel 30. The channel 30 is adapted to the oxygen branch tube 11 to prevent dust from entering the box body 21 from the gap between the channel 30 and the oxygen branch tube 11. Complete the storage of the nasal cannula oxygen head 13. After storing the nasal cannula oxygen head 13, clean and disinfect the oxygen tubing and place it in a storage bag to prevent cross-infection between the nasal cannula oxygen head 13 and other parts of the oxygen tubing.

[0054] It should be noted that the retaining ring structure 23 has a certain degree of elasticity. During use, the space at the opening of the retaining ring structure 23 is widened. When the oxygen inhalation tube 11 is inserted into the retaining ring structure 23, the tension applied to the retaining ring structure 23 is released, allowing the retaining ring structure 23 to hold the oxygen inhalation tube 11 in place, preventing it from detaching. This connects the storage box 20 to the oxygen inhalation tube. The inner wall of the retaining ring structure 23 and the outer wall of the oxygen inhalation tube 11 have a clearance fit, allowing the retaining ring structure 23 to slide up and down along the oxygen inhalation tube 11 for easy movement. The storage box 20 is connected to the oxygen inhalation tube. When oxygen inhalation is not needed, the storage box 20 is simply pushed to the nasal cannula oxygen head 13, and the nasal cannula oxygen head 13 is placed inside the storage box 20 to protect it from dust and prevent contamination.

[0055] The protrusion 27 of the lid 22 engages with the groove 26 of the body 21, preventing dust and bacteria from entering the body 21 through the gap between the lid 22 (without the protrusion 27) and the body 21 (without the groove 26), thus contaminating the cleaned and disinfected oxygen tubing. To ensure a tight fit between the lid 22 and the body 21 and prevent the lid 22 from detaching, a snap-fit ​​structure 46 can also be used. Different types and sizes of nasal cannula oxygen heads 13 require different compatible storage containers 25. When storing different types and sizes of nasal cannula oxygen heads 13, such as single nasal cannula oxygen heads 13 or detachable nasal cannula oxygen heads 13, a compatible storage container 25 can be used instead of a new storage box 20, saving resources and production costs.

The double seal achieved by the interlocking of the protrusion 27 of the lid 22 with the groove 26 of the body 21 and the seal of the receiver 25 effectively prevents dust from entering and external contamination from entering.

[0056] When using the storage box 20, the channel 30 is switched from a closed state to an open state using the sealing device 40 to facilitate the placement of the oxygen inhalation tube 11 when placing the nasal plug oxygen inhalation head 13. When not using the storage box 20, the channel 30 is switched from an open state to a closed state using the sealing device 40 to prevent dust from entering and external contamination.

[0057] by Figure 1 For reference, the first direction X is the horizontal direction from the first storage slot 24 to the second storage slot 29; the second direction Y is the horizontal direction from the right sealing device 40 to the left first through slot 31; and the third direction Z is the direction in which the opening of the box 21 is vertically upward. The first direction X, the second direction Y, and the third direction Z intersect each other perpendicularly.

[0058] In order to enable the sealing device 40 to switch the open and closed states of channel 30, in an optional embodiment, refer to Figures 3-9 The box body 21 has a movable groove 28, and a sealing device 40 is fixed inside the movable groove 28. The sealing device 40 includes a sealing structure 41, a return spring 44, and a limiting member 47. One end of the return spring 44 is connected to the bottom of the sealing structure 41, and the other end is fixed to the bottom of the movable groove 28. The limiting member 47 is used to limit the movement distance of the sealing structure 41. A limiting hole 48 is provided on the inner wall of the box body 21, and the limiting member 47 moves within the limiting hole 48. Specifically, the sealing device 40 includes a sealing body 42 and a sealing plate 43 adapted to the second through groove 32.

[0059] It is understood that the movable groove 28 connects to the recess 26, and the closing structure 41 moves up and down within the space formed by the movable groove 28, the overlapping space of the recess 26 above the movable groove 28 and the first through groove 31, and the second through groove 32, thereby closing and opening the channel 30 formed by the first through groove 31 and the second through groove 32. Specifically, the length of the movable groove 28 in the first direction X is greater than the length of the first through groove 31 in the first direction X, and the length of the movable groove 28 in the second direction Y is equal to the length of the recess 26 in the second direction Y. The movable groove 28 is located below the recess 26 and connects to the recess 26.

[0060] Combination Figures 3-6 When the lid 22 and the body 21 are open, the return spring 44 is in its natural state, and the closing structure 41 completely closes the first through slot 31. Specifically, the closing body 42 completely closes the first through slot 31, and the closing plate 43 extends beyond the top surface of the body 21. At this time, the limiting member 47 does not limit the movement distance of the closing structure 41.

[0061] Combination Figure 9When the lid 22 and the body 21 are closed, the sealing structure 41 moves downward, the return spring 44 is compressed and moves downward, and the second through groove 32 penetrating the protrusion 27 and the first through groove 31 of the body 21 are joined to form a channel 30. The part of the protrusion 27 adjacent to the second through groove 32, the sealing plate 43 and the part of the sealing body 42 seal the channel 30 and the first through groove 31. Because the sealing plate 43 is subjected to the upward elastic force of the return spring 44 and the downward pressure of the lid 22, the outer edge of the sealing plate 43 is tightly fitted with the outer wall of the second through groove 32 on the protrusion 27, preventing dust from entering the body 21 from the gap between the sealing plate 43 and the second through groove 32. It should be noted that when the nasal plug oxygen head 13 is detachable, the nasal plug oxygen head 13 is directly placed into the body 21 without using the limiting member 47 to limit the sealing structure 41, and the lid 22 and the body 21 are closed to store the nasal plug oxygen head 13. To prevent dust from entering the box 21 through the gap between the sealing plate 43 and the second through groove 32, other dustproof designs can be implemented on the part of the sealing plate 43 that contacts the second through groove 32.

[0062] Combination Figures 7-8 The limiting hole 48 is formed on the right inner wall of the box 21 in the opposite direction of the second direction Y. The limiting hole 48 penetrates the inner wall of the box 21 in the second direction Y until it enters the inner wall of the box 21 in the opposite direction of the second direction Y. The limiting hole 48 formed on the left inner wall of the box 21 is similar in structure to the limiting hole 48 formed on the right inner wall of the box 21 in the opposite direction, and will not be described in detail.

[0063] When the lid 22 and body 21 are closed and an oxygen tube is placed inside, the sealing structure 41 is compressed below the groove 26, and the limiting member 47 is inserted through the limiting hole 48 on the inner wall of the body 21. The limiting member 47 prevents the sealing body 42 from moving upward along the third direction Z. The protrusion 27 adjacent to the second through groove 32 and the oxygen branch tube 11 seal the channel 30 and the first through groove 31, preventing dust from entering the body 21 from the gap between the oxygen branch tube 11 and the first through groove 31 and the second through groove 32.

[0064] By switching the open and closed states of the channel 30 through the sealing device 40, the closed state of the storage box 20 when it is not in use and the closed state of the storage box 20 when it is used to store the oxygen inhalation tube will not cause dust from outside the channel 30 to contaminate the inside of the storage box 20 due to the opening of the channel 30.

[0065] In one alternative embodiment, refer to Figure 1 , Figure 9 The box body 21 has a second storage slot 29 inside. The lid 22 is connected to a hook 45.

[0066] Understandably, wiping reusable oxygen tubing after use is a crucial step in the cleaning process. After oxygen therapy, residual moisture and secretions from the patient's exhaled breath may remain. Timely wiping prevents these substances from drying and accumulating on the tubing, facilitating subsequent cleaning and disinfection. The second storage slot 29 within the housing 21 can hold disposable medical cotton balls and other cleaning supplies, making it convenient to wipe the oxygen tubing clean and avoiding prolonged searching for cleaning supplies, which could cause the patient's exhaled moisture and secretions to dry. When hanging the oxygen tubing, it can be suspended using the hook 45 on the lid 22. This prevents the oxygen tubing from falling off due to the weight of the housing 21 shifting the center of gravity when directly suspended. It should be noted that the hook 45 is movable. When not in use, the hook 45 is flush with the top surface of the lid 22; when in use, the hook 45 forms an angle with the top surface of the lid 22 and is no longer flush.

[0067] The snap ring structure 23 of this invention is detachably connected to the oxygen inhalation tube 11 and can slide up and down on the oxygen inhalation tube 11, making it convenient to use. Simply open the storage box 20 and push or pull it to place the nasal plug oxygen inhalation head 13 into the storage box 20. Closing the box lid 22 completes the storage of the nasal plug oxygen inhalation head 13, preventing dust and contamination. The sealing device 40 is used to switch the open and closed states of the channel 30. The storage container 25 fits snugly against the nasal plug oxygen inhalation head 13 to achieve a seal. The protrusion 27 of the box lid 22 engages with the groove 26 of the box body 21 for a dustproof seal. The sealing of the storage container 25 and the sealing device 40 together seal the channel 30, providing multiple layers of sealing that effectively prevent dust from entering and avoid external contamination from entering the box body 21 through the channel 30. This invention can also be used in conjunction with oxygen tube storage bags to store the entire oxygen tube and prevent cross-contamination.
