Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically a pressure ulcer prevention nasogastric tube fixation device. Background Technology

[0002] A nasogastric tube is a commonly used medical assistive device, mainly used to provide nutritional support or perform gastrointestinal decompression for patients who cannot eat orally. It is usually a soft and flexible tube, with one end inserted into the patient's stomach through the nasal cavity or mouth, and the other end connected to a nutrient solution delivery device or a negative pressure suction device.

[0003] The adhesive parts used in some existing nasogastric tube fixation devices often become abnormally sticky and difficult to tear. This not only increases the difficulty of changing the nasogastric tube, but may also cause unnecessary pain and discomfort to the patient. In addition, for nasal patients who need long-term tube placement, the existing fixation methods often cause the patient's skin to be under pressure for a long time due to improper fixation angle or material problems, which can lead to pressure sores. Pressure sores not only cause great pain to patients, but may also lead to serious complications such as infection, affecting the patient's recovery process. Utility Model Content

[0004] The purpose of this utility model is to provide a nasogastric tube fixation device to solve the problems mentioned in the background above.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a pressure ulcer prevention nasogastric tube fixation device, comprising: a fixing plate and an angle fixing component, wherein an anti-slip layer is fixedly provided on the inner side of the fixing plate, and an application mechanism is fixedly provided on the side of the fixing plate;

[0006] The application mechanism includes a connecting seat fixedly disposed on the side of the fixed card plate. A silicone application plate is hinged to the side of the connecting seat.

The embodiments of this utility model will be described below based on its overall structure.

[0023] Reference Figures 1 to 5 In this embodiment of the present invention, a pressure ulcer prevention nasogastric tube fixation device includes: a fixing plate 1 and an angle fixing component 5. One end of the surface of the nasogastric tube is connected to the fixing plate 1 by a snap-fit. An anti-slip layer 3 is provided on the inner side of the fixing plate 1 to ensure that the nasogastric tube is stable and does not slide inside the fixing plate 1, effectively preventing displacement caused by movement or contact. In addition, an applicator 4 is cleverly provided on the side of the fixing plate 1, which provides additional protection for the stable fixation of the nasogastric tube. Meanwhile, the other end of the nasogastric tube is connected to the angle fixing component 5 by a snap-fit, which allows for flexible adjustment of the direction of the nasogastric tube.

[0024] The connecting seat 41 is fixedly mounted on the side of the fixing plate 1. The side of the connecting seat 41 is hinged to the silicone dressing plate 42, so that the silicone dressing plate 42 can be adjusted at an angle according to the patient's facial contours to ensure a good fit. The silicone dressing plate 42 has a placement groove 43 in the middle for inserting a medical sponge 44. The surface of the medical sponge 44 is evenly distributed with ventilation holes 45. These ventilation holes help the skin breathe and reduce the risk of pressure sores caused by prolonged pressure. The bottom of the silicone dressing plate 42 is filled with medical hot melt pressure-sensitive adhesive 46. This pressure-sensitive adhesive can ensure that the silicone dressing plate 42 is tightly attached to the patient's skin and provides a stable fixation effect.

[0025] The first adjusting tube 51 and the second adjusting tube 52 are fixedly sleeved onto the other end of the nasogastric tube. A connecting rod 53 is fixedly installed above the first adjusting tube 51 and the second adjusting tube 52. A movable frame 54 is rotatably mounted on the surface of the connecting rod 53, allowing the movable frame 54 to rotate within a certain range. The other end of the movable frame 54 is movably locked to the rotating shaft 55. By rotating the rotating shaft 55, the angle of the second adjusting tube 52 relative to the first adjusting tube 51 can be easily adjusted, thereby adjusting the direction of the nasogastric tube. After adjusting to the appropriate position, the rotation of the rotating shaft 55 can be restricted by rotating the fixing nut 56 above the rotating shaft 55, ensuring the stability of the nasogastric tube direction. The fixing plate 1, the anti-slip layer 3, and the 270-degree slots of the first adjusting tube 51 and the second adjusting tube 52 can be easily and stably locked onto the nasogastric tube to prevent slippage.

[0026] To ensure the stability of the medical sponge 44 within the placement groove 43, a retainer 6 is fixedly installed on the side of the silicone dressing plate 42. An insertion hole 7 is opened above the retainer 6, and an insertion rod 9 is fixedly installed below the pressure rod 8. When it is necessary to fix the medical sponge 44 in the placement groove 43, simply insert the pressure rod 8 into the insertion hole 7 through the insertion rod 9 below it. At this time, the pressure rod 8 is located directly above the medical sponge 44, and by pressing and fixing the medical sponge 44, it is ensured that it will not fall off due to movement or contact during use.

[0027] The working principle of this utility model is as follows:

[0028] One end of the nasogastric tube is fixedly connected to a fixing plate 1. The anti-slip layer 3 on the inner side of the fixing plate 1 ensures that the nasogastric tube is stable and does not slide. On the side of the fixing plate 1, there is an application mechanism 4. The application mechanism 4 includes a silicone application plate 42 hinged to a connecting seat 41. A medical sponge 44 is inserted into the placement groove 43 in the middle of the silicone application plate 42. The vent holes 45 on the surface of the medical sponge 44 help the skin to breathe and reduce the risk of pressure sores. The medical hot melt pressure-sensitive adhesive 46 filled under the silicone application plate 42 allows the silicone application plate 42 to be tightly applied to the philtrum of the patient, providing a stable fixation effect. The medical hot melt pressure-sensitive adhesive 46 can be slightly heated, such as by using hot water to moisten it, making the silicone application plate 42 easier to separate, reducing the pulling and damage to the skin.

[0029] When it is necessary to fix the nasogastric tube, the silicone dressing plate 42 is angled by the connecting seat 41 to adapt to the facial contours of different patients, and then it is attached to the patient's skin by medical hot melt pressure-sensitive adhesive 46. In order to fix the medical sponge 44, the pressure rod 8 is inserted into the insertion hole 7 of the card seat 6 through the insertion rod 9 below it, ensuring the stability of the position of the medical sponge 44. At the same time, the softness and breathability of the medical sponge 44 provide the patient with additional comfort and protection.

[0030] The other end of the nasogastric tube is fixed and adjusted by an angle fixing component 5, which includes a first adjusting tube 51 and a second adjusting tube 52. The other end of the movable frame 54 is movably connected to a rotating shaft 55. By rotating the rotating shaft 55, the relative angle between the second adjusting tube 52 and the first adjusting tube 51 can be adjusted, thereby adjusting the direction of the nasogastric tube. This adjustment method can prevent the nasogastric tube from obstructing the mouth and improve the patient's comfort. After adjusting to the appropriate position, the rotation of the rotating shaft 55 can be restricted by rotating the fixing nut 56 above the rotating shaft 55, thus ensuring the stability of the nasogastric tube direction.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
