Description

Technical Field

[0001] This utility model belongs to the field of medical equipment technology, specifically a skin protection device for nasal high-flow oxygen therapy. Background Technology

[0002] High-flow-rate oxygen therapy (HFlowO2) is a treatment method that delivers a high-flow-rate, temperature-controlled, and humidified mixture of oxygen and air to patients via specialized equipment. It delivers this mixture directly to the patient through a non-sealed nasal cannula, ensuring a specific oxygen concentration. HFlowO2 is characterized by: providing a high-flow-rate (up to 60 L / min), temperature-controlled, and humidified mixture of oxygen and air via specialized equipment, delivered to the patient through a nasal cannula; adjustable oxygen concentration between 21% and 100%; and features high flow rate, stable oxygen concentration, and heating and humidification, thereby reducing airway irritation and improving patient comfort and oxygenation effectiveness.

[0003] When using it, the nasal cannula needs to be fixed under the patient's nose with an elastic band so that the end of the nasal cannula can be stably inserted into the patient's nose. The elastic band should generally wrap around the entire head to ensure the stability of the nasal cannula.

[0004] However, nasal high-flow oxygen therapy uses an elastic band to fix the nasal cannula. Since different patients have significantly different head contours and irregular shapes, the elastic band is prone to shifting position during daily activities, especially head movements. This shift in position changes the pressure applied to the face, and this instability and uneven pressure distribution greatly increases the risk of device-related pressure injuries to the face and above the ears, severely impacting the patient's treatment experience and recovery process. Therefore, a skin protection device for nasal high-flow oxygen therapy is proposed to address these issues. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art and solve at least one of the technical problems mentioned in the background art, this utility model proposes a skin protection device for nasal high-flow oxygen therapy.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0017] Specific implementation examples are given below. Example

[0018] Please see Figure 1 - Figure 5This utility model provides a skin protection device for nasal high-flow oxygen therapy, including a connecting strip 1; an elastic band 2 is fixedly connected to the end of the connecting strip 1; an oxygen tube 3 is installed on the side wall of the connecting strip 1; rectangular frames 4 slide on the outer walls of both ends of the elastic band 2; ear hooks 41 are fixedly connected to the bottom of the rectangular frames 4; a limiting rod 44 is slidably connected through the side wall of the rectangular frames 4; multiple sets of through holes 8 are opened on the side wall of the elastic band 2; the end of the limiting rod 44 slides through the inner wall of the through hole 8. During operation, the connecting strip 1 and the oxygen tube 3 are fixed to the patient's face by the elastic band 2. To reduce the positional change of the elastic band 2 during use, the device is designed to ensure the patient's comfort. The instability and uneven distribution of facial pressure can lead to the risk of device-related pressure injuries to the face and above the ear. The ear hook 41, which is fixed to the bottom of the rectangular frame 4, can be hung on the patient's ear. When it is necessary to adjust the position of the ear hook 41 according to the position of the patient's ear, the limiting rod 44 can be moved to disengage it from the inner wall of the through hole 8. At this time, the rectangular frame 4 can be pushed to adjust the position of the ear hook 41, reducing the risk of slippage of the elastic band 2 and ensuring that the pressure on the patient's face and above the ear is even, thus improving the patient's wearing comfort. After adjustment, the limiting rod 44 can be inserted into the inner wall of the through hole 8 to ensure the stability of the ear hook 41. Example

[0019] Furthermore, such as Figure 1 - Figure 2 As shown, a protective film 52 is in contact with the middle of the connecting strip 1; a mesh double-sided adhesive 5 is adhered to the sidewall of the protective film 52; the sidewall of the end of the mesh double-sided adhesive 5 is adhered to the sidewall of the connecting strip 1; the end of the oxygen tube 3 is adhered to the sidewall of the mesh double-sided adhesive 5; a shielding film 51 is adhered to the sidewall of the mesh double-sided adhesive 5 near the end of the oxygen tube 3. During operation, the protective film 52 and the sidewall of the connecting strip 1 contact the patient's cheek and below the nose. The protective film 52 is made of a skin-friendly material, and the sidewall of the connecting strip 1 is made of an elastic material, which improves the patient's comfort. When the protective film 52 is contaminated or damaged, simply remove the oxygen... Peel tube 3 off the side wall of double-sided mesh tape 5, and then peel double-sided mesh tape 5 off the side wall of connecting strip 1. At this time, the masking film 51 will be removed along with double-sided mesh tape 5, so that the masking film 51 can be replaced. During installation, stick the new masking film 51 to double-sided mesh tape 5, and then stick double-sided mesh tape 5 to connecting strip 1, ensuring that the masking film 51 is placed in the middle of connecting strip 1. Then stick oxygen tube 3 to double-sided mesh tape 5. In addition, the masking film 51 can be stuck to double-sided mesh tape 5 and on the same side as oxygen tube 3, which reduces the adhesion of unused double-sided mesh tape 5 to foreign objects and improves practicality. Example

[0020] Furthermore, such as Figure 2 and Figure 5 As shown, a rectangular groove 7 is provided on the side wall of the end of the connecting strip 1; a rotating plate 61 is rotatably connected to the inner wall of the rectangular groove 7; a push plate 6 is fixedly connected to the side wall of the rotating plate 61; the side wall of the rotating plate 61 contacts the side wall of the end of the mesh double-sided adhesive 5. During operation, when the protective film 52 needs to be replaced and the mesh double-sided adhesive 5 needs to be peeled off, the push plate 6 can be pulled, and the push plate 6 will drive the rotating plate 61 to rotate. In this way, the end of the mesh double-sided adhesive 5 will be lifted up, and medical staff can pull the lifted end of the mesh double-sided adhesive 5 to peel it off, which improves convenience. When adhering the mesh double-sided adhesive 5, it is necessary to ensure that the side wall of the end of the mesh double-sided adhesive 5 covers the side wall of the rotating plate 61, which can reduce the risk of the rotating plate 61 detaching from the inner wall of the rectangular groove 7. Example

[0021] Furthermore, such as Figure 2 - Figure 4 As shown, a connecting rod 42 is rotatably connected above the end of the limiting rod 44; a sliding rod 43 is rotatably connected above the end of the connecting rod 42; the sliding rod 43 is slidably connected to the inner wall of the end of the rectangular frame 4. During operation, when the limiting rod 44 needs to be moved, the sliding rod 43 can also be pushed. The end of the sliding rod 43 will rotate with the end of the connecting rod 42, and at the same time, the other end of the connecting rod 42 will rotate with the end of the limiting rod 44. The limiting rod 44 will move with the change of the angle of the connecting rod 42, increasing the versatility of releasing the limiting rod 44 and ensuring that it can be operated at different angles, thus improving its practicality.

[0022] Furthermore, such as Figure 4 As shown, a spring 45 is fixedly connected to the inner wall of the end of the rectangular frame 4; the end of the spring 45 is fixedly connected to the end of the sliding rod 43. During operation, when the sliding rod 43 moves, the spring 45 will elastically deform accordingly. The spring 45 will push the sliding rod 43 to move outward of the rectangular frame 4 through its own elasticity, ensuring that the limiting rod 44 can be quickly reset without repeated pushing, and ensuring the stability of the limiting rod 44.

[0023] Furthermore, such as Figure 4 As shown, a roller 46 is rotatably connected to the inner wall of the rectangular frame 4; the roller 46 rolls on the end of the elastic band 2. During operation, when the rectangular frame 4 is pushed to move, the roller 46 will roll on the end of the elastic band 2 to ensure the smooth movement of the rectangular frame 4, reduce the risk of friction between the elastic band 2 and the rectangular frame 4, and improve its service life.

[0024] Working principle: The connecting strip 1 and oxygen tube 3 are fixed to the patient's face by the elastic band 2. To reduce the risk of device-related pressure injury to the face and above the ear caused by the elastic band 2 shifting position during use, which could lead to unstable and uneven pressure distribution, an ear hook 41 fixed to the bottom of the rectangular frame 4 can be hung on the patient's ear. When it is necessary to adjust the position of the ear hook 41 according to the patient's ear position, the limiting rod 44 can be pulled to move it away from the inner wall of the through hole 8. At this time, the rectangular frame 4 can be pushed to adjust the position of the ear hook 41, reducing the risk of the elastic band 2 slipping and ensuring that the pressure on the patient's face and above the ear is even, thus improving the patient's wearing comfort. After adjustment, insert the limiting rod 44 into the inner wall of the through hole 8 to ensure the stability of the hook 41. Alternatively, push the sliding rod 43. At this time, the end of the sliding rod 43 will rotate with the end of the connecting rod 42, and the other end of the connecting rod 42 will rotate with the end of the limiting rod 44. The limiting rod 44 will move with the angle of the connecting rod 42, increasing the versatility of releasing the limiting rod 44 and ensuring that it can be operated at different angles, thus improving its practicality. Both of these methods will cause the sliding rod 43 to move and compress the spring 45. When the pressure is stopped, the spring 45 will push the sliding rod 43 to move in the opposite direction to reset through its own elasticity, and the limiting rod 44 will also move in the opposite direction to reset.

[0025] In addition, the protective film 52 and the side wall of the connecting strip 1 are in contact with the patient's cheeks and below the nose. The protective film 52 is made of a skin-friendly material, and the side wall of the connecting strip 1 is made of an elastic material, which can improve the patient's comfort. When the protective film 52 is contaminated or damaged, simply tear the oxygen tube 3 off the side wall of the double-sided mesh tape 5. Then, pull the push plate 6, which will drive the rotating plate 61 to rotate. This will cause the end of the double-sided mesh tape 5 to lift up, and medical staff can then pull the lifted end of the double-sided mesh tape 5 to remove it from the connecting strip 1. Peel off the side wall of connector 1. At this time, the masking film 51 will be removed along with the mesh double-sided tape 5, so that the masking film 51 can be replaced. During installation, stick the new masking film 51 to the mesh double-sided tape 5, and then stick the mesh double-sided tape 5 to connector 1, ensuring that the masking film 51 is placed in the middle of connector 1. Then stick the oxygen tube 3 to the mesh double-sided tape 5. In addition, the masking film 51 can be stuck to the mesh double-sided tape 5 and on the same side as the oxygen tube 3, which reduces the adhesion of unused mesh double-sided tape 5 to foreign objects and improves practicality.

[0026] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
