Liquid diet, nutritional supplements, medicines and water can be provided smoothly and effectively through the nasogastric tube. The corresponding fixing device is to maintain the stable position of the nasogastric tube to prevent it from shifting or falling off, thereby ensuring that the nutrient solution or medicine can be smoothly delivered to the patient's digestive tract.

[0003] However, current measures for fixing nasogastric tubes usually use medical tape or 3M tape to stick them on the cheeks. However, the stickiness of the tape is easily affected by temperature and humidity. In addition, nasogastric tubes usually require a long period of use, during which the patient's cheeks are prone to heat, sweating and oiliness, which causes the stickiness of the tape to decrease and the nasogastric tube to shift, thereby increasing the patient's discomfort and pain, which is not conducive to the patient's rest.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-4The utility model provides a nasogastric tube fixing head-mounted device, comprising a plastic ring 1, the inner wall of the plastic ring 1 is provided with teeth 2, the outer surface of the plastic ring 1 is slidably connected with a sleeve shell 3, the bottom surface of the sleeve shell 3 is fixedly connected with a gauze 4, the bottom end of the gauze 4 is fixedly connected with a rubber plate 5, the outer surface of the gauze 4 is fixedly connected with a Velcro 1 6, and the outer surface of the gauze 4 is fixedly connected with a Velcro 2 7; the material of the plastic ring 1 is mainly soft rubber material, the sleeve shell 3 can slide on the plastic ring 1, and rely on the teeth 2 to clamp at a certain position of the plastic ring 1, the gauze 4 is mainly a three-layer composite woven medical gauze 4, and the rubber plate 5 itself has good Deformability enables it to adapt to the patient's chin; the patient can wear the plastic ring 1 on the upper head, and fix the shell 3 between the parietal bone and the temporal bone on both sides of the head, and place the rubber plate 5 on the patient's mandible to tighten the gauze 4. At this time, the nasogastric tube can be tightly attached to the surface of Velcro 1 6, and Velcro 2 7 can be covered on the nasogastric tube and adhered to Velcro 1 6 to effectively fix the nasogastric tube. At this time, no matter the patient sweats, the body surface temperature rises or oil is secreted, it will not affect the nasogastric tube, thereby solving the problem of the decrease in the viscosity of the tape and the displacement of the nasogastric tube, which in turn increases the patient's discomfort and pain.

[0024] A spring 10 is fixedly connected to the outer surface of the baffle 9, and the other end of the spring 10 is fixedly connected to the outer surface of the limit plate 8. The outer surface of the baffle 9 and the outer surface of the tooth 2 are mutually clamped. The spring 10 can always push the baffle 9, forcing the baffle 9 to be tightly attached to the outer surface of the tooth 2. The angle of the surface of the tooth 2 in contact with the baffle 9 is close to ninety degrees, and the other side of the tooth 2 is inclined at nearly forty-five degrees, thereby forcing the shell 3 to move only clockwise along the trajectory of the plastic ring 1. At the same time, the tooth 2 with a forty-five-degree inclined surface can also reduce the resistance of the baffle 9 when sliding.

[0025] A limit plate 8 is provided on the inner side wall of the shell 3, and a baffle 9 is rotatably connected to the inner side wall of the shell 3. The limit plate 8 serves as a limit for the baffle 9 and also provides a fixing function for the spring 10. The spring 10 can push the baffle 9 with the limit plate 8 as a fixed point. The outer surface of the baffle 9 is in close contact with the outer surface of the limit plate 8. The limit plate 8 can force the baffle 9 to tilt counterclockwise only with the connection point between the baffle 9 and the shell 3 as a circle, forcing the shell 3 to move only clockwise along the trajectory of the plastic ring 1, thereby preventing the risk of displacement of the shell 3 and its lower components due to head tilt or displacement during use.

[0026] A positioning hole 11 is provided on the inner side of the casing 3, and a limiting rod 12 is slidably connected to the inner wall of the positioning hole 11. The limiting rod 12 is located at an end away from the casing 3 and is fixedly connected to a wheel frame 13. A roller 14 is installed inside the wheel frame 13. The outer surface of the roller 14 is slidably connected to the outer surface of the plastic ring 1. The limiting rod 12 can assist the movement of the wheel frame 13 in the direction given by the positioning hole 11 to prevent the wheel frame 13 from shifting during movement. A bearing is fixed to the inner wall of the roller 14, and both ends of the bearing are installed inside the wheel frame 13. At the same time, during the movement of the casing 3, the roller 14 can rotate on the surface of the plastic ring 1, thereby reducing the resistance between the casing 3 and the plastic ring 1. A rubber ring is sleeved on the surface of the roller 14, and the rubber ring can increase the friction between the roller 14 and the plastic ring 1.

[0027] The two sides of the wheel frame 13 are slidably connected to the inner wall of the casing 3. The inner wall of the wheel frame 13 is provided with a slideway. The side of the wheel frame 13 is provided with a slide bar, which slides on the slideway, so that the wheel frame 13 is not easily displaced when moving.

[0028] The inner wall of the casing 3 is rotatably connected with a threaded rod 15, and the threaded rod 15 is rotatably connected to the outer surface of the wheel frame 13 at one end away from the inner side of the casing 3. The threaded rod 15 is fixedly connected with a turning handle 16 at one end away from the wheel frame 13. Turning the turning handle 16 can drive the threaded rod 15 to rotate. The threaded rod 15 can squeeze or relax the pressure on the wheel frame 13 when rotating. When the pressure is too high, the rubber ring on the surface of the roller 14 will be deformed, so that the contact area between the rubber ring and the plastic ring 1 is increased, thereby increasing the friction, and then the casing 3 is fixed on the plastic ring 1 and is not easy to move. When the pressure becomes smaller or there is no pressure, the roller 14 can roll on the plastic ring 1, so that it can move.

[0029] The side wall of the shell 3 is fixedly connected with a breathable plate 17, and a breathable plate 2 18 is inserted on one side of the breathable plate 17. The inner sides of the breathable plates 17 and 18 are both provided with air holes 19. The breathable plates 17 and 18 mainly contact the two sides and the back of the patient's head. The breathable plates 17 and 18 have good deformation characteristics, which can reduce the discomfort caused by the protrusion of foreign matter brought by the plastic ring 1 when the patient lies on the bed, and the air holes 19 can facilitate the heat dissipation of the patient's head. The main material of the breathable plates 17 and 18 is sponge, which can play a good sweat absorption role, thereby making the device more practical.

[0030] The outer surface of the gauze 4 is fixedly connected with six rows of male buckles 20, wherein the outer surfaces of two rows of the male buckles 20 are buckled and connected with female buckles 21, and the outer surfaces of the female buckles 21 are fixedly connected with an adjustment plate 22. There are two rows of female buckles 21, and each row of female buckles 21 can correspond to three rows of male buckles 20 in sequence, so that the Velcro 1 6 and Velcro 2 7 can be driven by the adjustment plate 22 to correspond to different heights according to the different face shapes or different age groups of the patients.

[0031] The outer surface of the adjustment plate 22 is fixedly connected with a tube clamping plate 23, and the A surface of the tube clamping plate 23 is fixedly connected to the outer surface of Velcro 1 6, and the B surface of the tube clamping plate 23 is fixedly connected to the outer surface of Velcro 2 7. The nasogastric tube can be inserted into the tube clamping plate 23, and the Velcro 1 6 can adhere to the surface of Velcro 2 7 when it is attached to the surface of Velcro 2 7, and can cover the nasogastric tube and the tube clamping plate 23 to prevent the nasogastric tube from falling off from the tube clamping plate 23.

[0032] Working principle: When the device needs to be used, first put the plastic ring 1 on the patient's head, and place the air permeable plate 1 17 and the air permeable plate 2 18 between the parietal bones and temporal bones on both sides of the head and the back of the head, then turn the handle 16 counterclockwise to force the threaded rod 15 to squeeze the wheel frame 13 and the roller 14. When the pressure is too high, the rubber ring on the surface of the roller 14 will deform, increasing the contact area between the rubber ring and the plastic ring 1, thereby increasing its friction, and then fixing the shell 3 on the plastic ring 1 and making it difficult to move. Then place the rubber plate 5 on the patient's mandible to fix the device as a whole on the patient's head, then clamp the nasogastric tube on the tube clamping plate 23, and attach Velcro 1 6 to Velcro 2 7 so that Velcro 1 6 covers the nasogastric tube, which can effectively fix the nasogastric tube.
