Description

Technical Field

[0001] This utility model relates to the field of nasal cannulas, and in particular to a high-flow oxygen therapy nasal cannula fixation patch assembly. Background Technology

[0002] High-flow-rate oxygen therapy is a technology that uses an air-oxygen mixing device to deliver a high flow rate of heated and humidified gas for respiratory support. This technology can generate positive end-expiratory pressure, maintain alveolar patency, and improve oxygenation by flushing out physiological dead space. As a key component of the high-flow-rate oxygen therapy system, the high-flow-rate oxygen nasal cannula's function is to accurately deliver oxygen to the patient's nasal cavity, ensuring that the patient receives the required oxygen flow rate and concentration.

[0003] Common high-flow oxygen therapy nasal cannulas consist of a nasal connector, a nasal plug, an oxygen tubing, and an oxygen inlet. One end of the nasal connector connects to the oxygen tubing, and the other end connects to the oxygen inlet, which in turn connects to the oxygen supply equipment. The nasal plug, fixed to the surface of the nasal connector, is directly inserted into the patient's nasal cavity to deliver oxygen. During oxygen therapy, patients need to perform daily activities such as turning over, sitting up, and walking. These movements can cause relative displacement between the nasal cannula and the nasal cavity, leading to the nasal plug slipping out and affecting the oxygen therapy effect. Existing high-flow oxygen therapy nasal cannulas have the following problems with the way the nasal plug is fixed: Existing nasal cannulas often use integrated elastic bands on both sides to secure the nasal plug to the patient's nasal cavity by fixing the elastic bands to the patient's head. Since nasal cannulas have a limited lifespan, if they are not replaced in time, nasal secretions may cause inflammation. Therefore, when replacing the nasal cannula, the integrated elastic bands are also replaced, resulting in a waste of resources and increased medical costs.

[0004] Therefore, this utility model provides a high-flow oxygen therapy nasal cannula fixation patch assembly to meet the requirements. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a high-flow oxygen therapy nasal cannula fixation patch assembly. By setting a detachable fixation patch assembly, the fixation patch assembly can be reused, reducing the consumption of medical resources and lowering medical costs. The above setting can solve the problem that when the nasal cannula is replaced, the integrated elastic band is also replaced, which leads to the waste of resources and increased medical costs.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A high-flow oxygen therapy nasal cannula fixation patch assembly includes a nasal tube, two nasal plugs fixed to the surface of the nasal tube, an oxygen hose fixed to one end of the nasal tube, and an oxygen inlet fixed to the end of the oxygen hose away from the nasal tube; and a fixation patch assembly for assisting in fixing the nasal plugs to the patient's nasal cavity, the fixation patch assembly being connected to the nasal tube and the nasal plugs respectively.

[0007] Optionally, the fixing patch assembly includes a connecting sleeve, a connecting block, a connecting strip, and a fixing patch. The connecting sleeve is fitted onto the surface of the nasal tube, and the nasal plug passes through the connecting sleeve. The connecting blocks are symmetrically fixed to one side of the nasal tube, and the two connecting blocks are respectively located on the sides of the two nasal plugs that are far apart from each other. There are two connecting strips, which are respectively fixed on the sides of the two connecting blocks that are far apart from each other. There are two fixing patches, which are respectively fixed inside the two connecting strips.

[0008] Optionally, the connecting sleeve has a connection port on the side away from the nasal plug.

[0009] Optionally, a through hole is provided on one side of the connecting sleeve, and the nose plug passes through the through hole.

[0010] Optionally, a limiting post is fixed to one side of the connecting strip, a locking block is engaged on the limiting post, and an elastic rope is threaded through the locking block.

[0011] Optionally, a limiting port and a rope threading port are sequentially provided on the top of the card block. Protrusions are fixed on both sides of the inner wall of the limiting port away from the rope threading port. The limiting port is engaged with the limiting post. The protrusions abut against the outer wall of the limiting post. One end of the elastic rope is threaded through the rope threading port.

[0012] Optionally, one of the connecting strips is fixed to one side with a plurality of guide frames, and one end of the elastic rope passes through the guide frame.

[0013] Optionally, a plurality of guide frames are fixed to one side of another connecting strip, one end of the elastic rope passes through the guide frame, and a socket is fixed to one side of each guide frame, the socket being inserted into the oxygen hose.

[0014] Optionally, a sliding ring is fitted onto the oxygen hose, and a plug is fixed to one side of the sliding ring, the plug being inserted into the socket.

[0015] Optionally, a drawstring buckle is provided at the end of the elastic cord away from the locking block.

[0016] Compared with the prior art, this utility model has at least the following beneficial effects: In the above solution, by setting a detachable fixing patch component, the fixing patch component does not need to be replaced when the nasal cannula is changed, which can be reused, thus reducing the consumption of medical resources and lowering medical costs. At the same time, the fixing patch component can help fix the nasal plug in the patient's nasal cavity, effectively resisting the pulling force and displacement caused by the patient's movement, ensuring the nasal plug is stably fixed in the patient's nasal cavity, and ensuring that oxygen can be accurately and effectively delivered to the patient's nasal cavity, thereby improving the stability and effectiveness of oxygen therapy.

[0017] By using connecting sleeves, connecting blocks, connecting strips, and fixing patches, the nasal plug can be fixed in place in the nasal cavity from different directions, effectively preventing the nasal plug from shifting or slipping out during patient activity. This ensures the stable fixation of the nasal plug in the patient's nasal cavity, ensuring that oxygen can be accurately and effectively delivered to the patient's nasal cavity, improving the stability and reliability of oxygen therapy. At the same time, the fixing patch components can be reused, reducing resource waste and lowering medical costs, which is in line with the concepts of environmental protection and conservation.

[0018] By incorporating connecting blocks, the stability of the nasal plug in the nasal cavity is enhanced, effectively preventing displacement or slippage of the nasal plug during patient activity. This ensures that oxygen therapy can be performed continuously and stably. At the same time, the connecting blocks limit the depth of the nasal plug insertion into the nasal cavity to a certain extent, preventing the nasal plug from completely blocking the nostrils. This allows patients to maintain normal respiratory function during oxygen therapy and prevents breathing from being affected by excessive insertion of the nasal plug, thus improving the patient's treatment experience and comfort.

[0028] like Figures 1 to 8 As shown, an embodiment of this utility model provides a high-flow oxygen therapy nasal cannula fixing patch assembly, including a nasal tube 1, two nasal plugs 4 fixed on the surface of the nasal tube 1, an oxygen hose 2 fixed to one end of the nasal tube 1, and an oxygen inlet 3 fixed to the end of the oxygen hose 2 away from the nasal tube 1. The high-flow oxygen therapy nasal cannula is composed of the nasal tube 1, nasal plugs 4, oxygen hose 2 and oxygen inlet 3. One end of the nasal tube 1 is connected to the oxygen hose 2, and the other end is inserted into the patient's nasal cavity through the nasal plugs 4 fixed on the surface. The oxygen hose 2 is connected to the oxygen inlet 3, and then connected to the oxygen supply equipment to realize the delivery of oxygen. The fixing patch component is used to assist in fixing the nasal plug 4 in the patient's nasal cavity. The fixing patch component is connected to both the nasal cannula 1 and the nasal plug 4. When changing the nasal cannula, there is no need to replace the fixing patch component, which can be reused, thus reducing the consumption of medical resources and lowering medical costs. At the same time, the fixing patch component can help fix the nasal plug 4 in the patient's nasal cavity, effectively resisting the pulling force and displacement caused by the patient's movement, ensuring the stable fixation of the nasal plug 4 in the patient's nasal cavity, ensuring that oxygen can be accurately and effectively delivered to the patient's nasal cavity, and improving the stability and effectiveness of oxygen therapy.

[0029] As one implementation method in this embodiment, such as Figures 2 to 4 and Figure 7As shown, the fixing patch assembly includes a connecting sleeve 5, connecting blocks 8, connecting strips 9, and fixing patches 21. The connecting sleeve 5 is fitted onto the surface of the nasal tube 1, and the nasal plug 4 passes through the connecting sleeve 5. The connecting sleeve 5 is made of silicone rubber, which has a certain strength and can maintain the structural integrity of the connecting sleeve 5 while ensuring elasticity, so that the connecting sleeve 5 can fit tightly against the nasal tube 1 and the nasal plug 4, providing stable support for the nasal plug 4. A through hole 7 is opened on one side of the connecting sleeve 5, through which the nasal plug 4 passes. A connecting port 6 is opened on the side of the connecting sleeve 5 away from the nasal plug 4. The connecting blocks 8 are symmetrically fixed on one side of the nasal tube 1, with the two connecting blocks 8 located at two... On the side of the nasal plugs 4 that are far apart from each other, there are two connecting strips 9, each fixed to the side of the two connecting blocks 8 that are far apart from each other. There are two fixing stickers 21, each fixed to the inside of the two connecting strips 9. In use, the connecting sleeve 5 is put on the surface of the nasal tube 1 through the connecting port 6, and the two nasal plugs 4 pass through the through hole 7. The through hole 7 can limit the position of the nasal plugs 4, so that the connecting sleeve and the nasal tube 1 are stably connected. The nasal plugs 4 are placed in a suitable position in the patient's nasal cavity, the connecting strips 9 are spread out to both sides, and the fixing stickers 21 are attached to the patient's face, so that the position of the nasal plugs 4 in the nasal cavity is fixed from different directions, effectively preventing the nasal plugs 4 from moving around in the patient's body. During movement, displacement or slippage occurs, ensuring the nasal plug remains stable and fixed in the patient's nasal cavity. This ensures accurate and effective oxygen delivery to the nasal cavity, improving the stability and reliability of oxygen therapy. When the nasal plug 4 is placed in the patient's nasal cavity, the two connecting blocks 8 are located on the opposite sides of the two nasal plugs 4 and abut against the patient's nostrils, forming additional support and fixation. These blocks limit the nasal plug 4 from both sides of the nostrils. Together with the connecting sleeve 5, connecting strip 9, and fixing sticker 21, they enhance the stability of the nasal plug 4 in the nasal cavity, effectively preventing displacement or slippage during patient movement and ensuring continuous and stable oxygen therapy. Furthermore, the design of the connecting block 8 abutting against the patient's nasal wing limits the depth of the nasal plug 4 inserted into the nasal cavity to a certain extent, ensuring that the nasal plug 4 does not completely block the nostrils, but rather allows for airflow. This creates a gap between the patient's nasal cavity and the nasal plug 4, allowing the patient to maintain normal respiratory function during oxygen therapy. The nasal plug 4 is not inserted too deeply, which affects the smoothness of breathing and improves the patient's treatment experience and comfort. When the nasal cannula needs to be replaced, the connecting sleeve 5 can be removed from the nasal tube 1 without replacing the fixing patch assembly. This allows for the reuse of the fixing patch assembly, reduces resource waste, lowers medical costs, and aligns with the concepts of environmental protection and conservation.

[0030] In this embodiment, as Figures 2 to 4As shown, a limiting post 11 is fixed to one side of the connecting strip 9. A locking block 12 is engaged on the limiting post 11. A limiting opening 13 and a rope-threading opening 15 are sequentially opened on the top of the locking block 12. Protrusions 14 are fixed on both sides of the inner wall of the limiting opening 13 away from the rope-threading opening 15. The limiting opening 13 engages with the limiting post 11, and the protrusions 14 abut against the outer wall of the limiting post 11. An elastic rope 16 is threaded through the locking block 12, with one end of the elastic rope 16 passing through the rope-threading opening 15. The limiting post 11 and the locking block 12 are engaged through the limiting opening 13, and the protrusions 14 on both sides of the inner wall of the limiting opening 13 abut against the outer wall of the limiting post 11. When the locking block 12 is engaged with the limiting post 11, the protrusions 14... The locking block 12 is able to resist the limiting post 11, preventing it from easily falling off the limiting post 11, thus providing a reliable connection base. During the patient's activities, the pulling force generated by the body's movements will not easily destroy this locking relationship, ensuring a stable connection between the connecting strip 9 and the locking block 12. This enhances the fixation stability of the nasal plug 4 in the nasal cavity, reduces the possibility of the nasal plug 4 slipping out, and ensures that oxygen therapy can be carried out continuously and stably. The elastic rope 16 is connected to the locking block 12 through the rope opening 15, further increasing the fixation strength and stability. The multi-part coordinated fixation method is more reliable than the single fixation method, further improving the quality and effect of oxygen therapy.

[0031] In this embodiment, as Figures 2 to 4 and Figure 6 As shown, there are two connecting strips 9. One connecting strip 9 has multiple guide frames 10 fixed to one side, and one end of the elastic rope 16 passes through the guide frame 10. The other connecting strip 9 has multiple guide frames 27 fixed to one side, and one end of the elastic rope 16 passes through the guide frame 27. Each guide frame 27 has a socket 18 fixed to one side. A sliding ring 19 is fitted onto the oxygen hose 2, and a plug 20 is fixed to one side of the sliding ring 19. The plug 20 is inserted into the socket 18, allowing the socket 18 to be inserted into the oxygen hose 2. The guide frames 10 and 27 provide a guiding path for the elastic rope 16, enabling the elastic rope 16 to stably move along a predetermined direction during the fixing process. Tighten the tension to ensure that the connecting strip 9 and the fixing sticker 21 fix the nasal plug 4 more evenly and stably. The guide frame 10 and the guide frame 27 also provide certain support for the two connecting strips 9, which helps to improve the support strength of the connecting strips 9. At the same time, the socket 18 fixed on one side of the guide frame 27 and the plug 20 fixed on the sliding ring 19 on the oxygen hose 2 are connected to each other, which realizes the convenient fixation of the oxygen hose 2. Connecting the oxygen hose 2 to the connecting strip 9 can effectively prevent the oxygen hose 2 from shifting or falling off during use, thereby ensuring the normal delivery of oxygen and avoiding the interruption or poor effect of oxygen therapy due to the displacement of the oxygen hose 2.

[0032] In this embodiment, as Figures 3 to 4As shown, the end of the elastic cord 16 away from the locking block 12 is provided with a drawstring buckle 22. The drawstring buckle 22 provides a convenient way to adjust the tightness of the elastic cord 16. Medical staff or patients can quickly adjust the tightness of the elastic cord 16 by pulling the drawstring buckle 22 according to their actual needs, which helps to improve the patient's treatment experience and comfort.

[0033] The working principle of the technical solution provided by this utility model is as follows: In use, the connecting sleeve 5 is fitted onto the surface of the nasal tube 1 through the connecting port 6, while the two nasal plugs 4 pass through the through holes 7. The through holes 7 limit the position of the nasal plugs 4, thus ensuring a stable connection between the connecting sleeve and the nasal tube 1. The nasal plugs 4 are placed in a suitable position in the patient's nasal cavity, with the two connecting blocks 8 abutting against the patient's nostrils, forming additional support and fixation. At the same time, this limits the depth of insertion of the nasal plugs 4 into the nasal cavity to a certain extent, preventing the nasal plugs 4 from completely blocking the nostrils, but allowing for airflow. This creates a gap between the patient's nasal cavity and the nasal plugs 4, allowing the patient to maintain normal respiratory function during oxygen therapy without affecting breathing due to excessive insertion of the nasal plugs 4. After ensuring smooth flow, the connecting strips 9 are extended to both sides, and the fixing sticker 21 is attached to the patient's face to fix the position of the nasal plug 4 in the nasal cavity from different directions. The locking block 12 with the elastic cord 16 is attached to the limiting post 11. Medical staff or patients can quickly adjust the tightness of the elastic cord 16 by pulling the elastic cord 16 in the drawstring buckle 22 according to actual needs, so as to improve the patient's treatment experience and comfort. When the nasal cannula needs to be replaced, the locking block 12 and the elastic cord 16 are removed, and the connecting sleeve 5 is removed from the surface of the nasal tube 1 through the connecting port 6. Then, the above installation steps are repeated to complete the connection with the new nasal cannula.

Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0035] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
