Description

Technical Field

[0001] This application relates to the technical field of oxygen inhalation tubes, and in particular to a nasal cannula for a non-slip, pressure ulcer-resistant humidification therapy device. Background Technology

[0002] The respiratory humidification therapy device utilizes a built-in high-performance airflow generator and oxygen delivery system to deliver oxygen directly to the alveoli of patients with chronic obstructive pulmonary disease through comfortable temperature adjustment and flexible self-controlled pressure, providing patients with optimized oxygen supply and expectoration experience with "optimal flow".

[0003] Existing nasal cannulas for respiratory humidification therapy devices are usually fixed to the patient's face with elastic bands. After wearing, the cannulas and elastic bands will compress the patient's skin, which can easily cause pressure sores with long-term use. In addition, for patients who need to wear nasogastric tubes at the same time, the nasogastric tube and the nasal cannulas of the respiratory humidification therapy device are prone to slippage and displacement at the nasal plug, requiring frequent adjustment and fixation. Utility Model Content

[0004] To alleviate facial pressure sores in patients and improve the stability and comfort of wearing nasal cannulas, this application provides a non-slip, pressure-sore-resistant humidification therapy nasal cannulas.

[0005] The above-mentioned inventive objective of this application is achieved through the following technical solutions:

[0006] A nasal cannula for a non-slip, pressure-ulcer-preventing humidified respiratory therapy device includes a nasal plug, an air inlet tube, and a flexible plate. Elastic bands are fixedly connected to both ends of the flexible plate. The nasal plug is fixedly disposed on the inner side of the top of the flexible plate. One end of the air inlet tube is connected to the nasal plug.

[0007] The outer wall of the nasal plug is provided with a limiting buckle, which is rotatably connected to the nasal plug and is used to limit the nasogastric tube.

[0008] The inner side of the flexible plate, away from the end of the nasal plug, is fixedly provided with a first foam dressing.

[0009] By adopting the above technical solution, a double-hole nasal plug is inserted into the patient's nasal cavity, and an external humidification therapy device is connected to the air inlet tube to deliver oxygen to the patient. The device is fixed to the patient's face by an elastic band. During use, the first foam dressing on the inner side of the soft plate increases the contact area with the face and protects the patient's skin, reducing device-related pressure injury to the face. This avoids device-related pressure injury that may easily occur between the device and the patient's skin under the nose after prolonged use. When the patient needs to wear a nasogastric tube at the same time, a limiting buckle is placed on the outer wall of the nasal plug to limit the nasogastric tube, making it less likely to slip or shift between the nasogastric tube and the nasal plug, thus improving the practicality of the device.

[0010] Optionally, an adjustment buckle is fixedly connected to one end of the elastic band near the flexible plate, and the adjustment buckle is used to adjust the tightness of the elastic band.

[0011] By adopting the above technical solution, the adjustment buckle can adjust the tightness of the elastic band. The adjustment buckle is set at the end of the elastic band near the soft plate. After the patient puts on the nasal cannula and elastic band, the adjustment buckle is located on the side of the patient's head, which is convenient for the patient to lie supine.

[0012] Optionally, a second foam dressing is fixedly connected to the inner side of the soft plate, and the second foam dressing is disposed below the nasal plug.

[0013] By adopting the above technical solution, a second foam dressing is placed below the nasal plug, which can protect the patient's nasal septum from pressure sores.

[0014] Optionally, the limiting buckle has a through hole inside, the inner diameter of the through hole is larger than the outer diameter of the nose plug, the nose plug is inserted into the through hole, and an arc-shaped notch is provided on one side of the limiting buckle. The limiting buckle is made of elastic material.

[0015] By adopting the above technical solution, when the patient needs to wear a nasogastric tube at the same time, the limiting buckle can slide along the outer wall of the nasal plug catheter, and the limiting buckle is placed on the outer wall of the nasal plug on one side of the nasogastric tube. Then the nasogastric tube is inserted into the arc-shaped notch, thereby achieving the purpose of fixing the nasogastric tube and the nasal plug catheter, so that the nasogastric tube and the nasal plug catheter of the respiratory humidification therapy device are not easy to slip off or shift at the nasal plug.

[0016] Optionally, the intake pipe is a corrugated pipe.

[0017] By adopting the above technical solution, the corrugated tube can adapt to the connection requirements of different angles and directions. When the patient moves or changes posture, it can maintain the stability of the air delivery tube, making it less likely to be stretched or flattened, thus keeping the airflow smooth.

[0018] In summary, this application includes at least one of the following beneficial technical effects:

[0019] 1. Insert the double-hole nasal plug into the patient's nasal cavity, connect the inlet tube to the humidification therapy device to deliver oxygen to the patient, and fix the device to the patient's face with an elastic band. During use, the first foam dressing on the inner side of the soft plate increases the contact area with the face and protects the patient's skin, reducing device-related pressure injury to the face and avoiding device-related pressure injury that may easily occur directly with the patient's skin under the nose after prolonged use. When the patient needs to wear a nasogastric tube at the same time, the limiting buckle is set on the outer wall of the nasal plug. The limiting buckle limits the nasogastric tube, making it less likely to slip or shift between the nasogastric tube and the nasal plug, thus improving the practicality of the device.

[0020] 2. When the patient needs to wear a nasogastric tube at the same time, the limiting buckle can slide along the outer wall of the nasal plug catheter. The limiting buckle is placed on the outer wall of the nasal plug on one side of the nasogastric tube, and then the nasogastric tube is inserted into the arc-shaped notch. This achieves the purpose of fixing the nasogastric tube and the nasal plug catheter, so that the nasogastric tube and the nasal plug catheter of the respiratory humidification therapy device are not easy to slip off or shift at the nasal plug.

[0021] 3. The adjustment buckle can adjust the tightness of the elastic band. The adjustment buckle is located at the end of the elastic band near the soft plate. After the patient has put on the nasal cannula and elastic band, the adjustment buckle is located on the side of the patient's head, making it convenient for the patient to lie supine.

[0027] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0028] This application discloses a nasal cannula for an anti-slip, pressure-ulcer-preventing humidified respiratory therapy device. (Refer to...) Figure 1-3The nasal cannula of the humidification therapy device includes a nasal plug 1, an inlet tube 2, and a flexible plate 3. The inlet tube 2 is a corrugated tube. Elastic bands 4 are fixedly connected to both ends of the flexible plate 3. The nasal plug 1 is fixedly installed on the inner top of the flexible plate 3, and one end of the inlet tube 2 is connected to the nasal plug 1. A limiting buckle 5 is movably installed on the outer wall of the nasal plug 1. The limiting buckle 5 is rotatably connected to the nasal plug 1 and is used to limit the nasogastric tube. A first foam dressing 6 is fixedly installed on the inner side of the flexible plate 3 away from the nasal plug 1. A second foam dressing 8 is fixedly connected to the inner side of the nasal plug 1. The second foam dressing 8 is located below the nasal plug 1. The second foam dressing 8 can protect the patient's nasal septum from pressure sores. An adjustment buckle 7 is fixedly connected to one end of the elastic band 4 near the soft plate 3. The adjustment buckle 7 can adjust the tightness of the elastic band 4. The adjustment buckle 7 is located at one end of the elastic band 4 near the soft plate 3. After the patient puts on the nasal plug 1 catheter and the elastic band 4, the adjustment buckle 7 is located on the side of the patient's head, which is convenient for the patient to lie supine. The double-hole nasal plug 1 is inserted into the patient's nasal cavity. The air inlet tube 2 is connected to a humidification therapy device to deliver oxygen to the patient. The device is fixed to the patient's face by the elastic band 4. During use, the first foam dressing 6 on the inner side of the soft plate 3 increases the contact area with the face and protects the patient's skin, reducing device-related pressure injury to the face. This avoids the possibility of device-related pressure injury that may easily occur between the device and the patient's skin under the nose after prolonged use. When the patient needs to wear a nasogastric tube at the same time, the limiting buckle 5 is placed on the outer wall of the nasal plug 1. The limiting buckle 5 limits the nasogastric tube, making it difficult for the nasogastric tube to slip or shift between the nasal plug 1 and the tube.

[0029] Reference Figure 4 The limiting buckle 5 has a through hole 9 inside, and the inner diameter of the through hole 9 is larger than the outer diameter of the nasal plug 1. The nasal plug 1 is inserted into the through hole 9. One side of the limiting buckle 5 is provided with an arc-shaped notch 10. The limiting buckle 5 is made of elastic material. When the patient needs to wear a nasogastric tube at the same time, the limiting buckle 5 can slide along the outer wall of the nasal plug 1 catheter. The limiting buckle 5 is placed on the outer wall of the nasal plug 1 on one side of the nasogastric tube, and then the nasogastric tube is inserted into the arc-shaped notch 10. This achieves the purpose of fixing the nasogastric tube and the nasal plug 1 catheter, so that the nasogastric tube and the nasal plug 1 catheter of the respiratory humidification therapy device are not easy to slip off or shift at the nasal plug 1.

[0030] The implementation principle of the anti-slip and pressure ulcer-preventing nasal plug 1 catheter of the present application embodiment is as follows: the double-hole nasal plug 1 is inserted into the patient's nasal cavity, the air inlet tube 2 is connected to the humidification therapy device to deliver oxygen to the patient, and the device is fixed to the patient's face by the elastic band 4. During use, the first foam dressing 6 on the inner side of the soft plate 3 increases the contact area with the face and protects the patient's skin, reducing device-related pressure damage to the face and avoiding device-related pressure damage that may easily occur directly with the patient's nasal skin after long-term use. When the patient needs to wear a nasogastric tube at the same time, the limiting buckle 5 can slide along the outer wall of the nasal plug 1 catheter. The limiting buckle 5 is sleeved on the outer wall of the nasal plug 1 on one side of the nasogastric tube, and then the nasogastric tube is inserted into the arc-shaped notch 10, thereby achieving the purpose of fixing the nasogastric tube and the nasal plug 1 catheter, so that the nasogastric tube and the nasal plug 1 are not easy to slip or shift.

[0031] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Any feature disclosed in this specification (including the abstract and drawings) may be replaced by other equivalent or similar features unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is only one example of a series of equivalent or similar features.
