[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] Reference Figure 1-6, an embodiment of the present invention provides: a severe nasal feeding device, including a nasal mask 7, both sides of the bottom end of the nasal mask 7 are fixedly connected with a tape 1, the top of one side of the nasal mask 7 is rotatably connected to a mounting block 9, both sides of the mounting block 9 are provided with a limiting groove 11, the limiting groove 11 is set as an arc structure, both ends of one side of the nasal mask 7 are fixedly connected with a push block 21, the top of one side of the nasal mask 7 is rotatably connected to the mounting block 9, two cavities 15 are provided inside the mounting block 9, and a notch is provided on one side of the cavity 15. Both sides of the bottom end of the mounting block 9 are fixedly connected with a fixing ring 2, the fixing ring 2 is set as a U-shaped structure, a rubber bag 17 is fixedly connected inside the cavity 15, and the bottom end of the rubber bag 17 is connected with a pipe 16, one end of the pipe 16 passes through the side wall of the cavity 15 and the fixing ring 2 in sequence and is connected with an air bag 3, the air bag 3 is set as a U-shaped structure, a nasogastric feeding tube body 24 is inserted into the air bag 3, the inner wall of the air bag 3 is fixedly connected with a protrusion 4, and physiological saline is stored inside the rubber bag 17.

[0037] Insert the nasogastric tube body 24 into the patient's nasal cavity, then place the nasal mask 7 on the patient's nose, and use the tape 1 to fix the nasal mask 7 to the patient's nose. Then rotate the mounting block 9 downward with your hand so that the fixing ring 2 is connected across the outside of the nasogastric tube body 24. When the mounting block 9 is rotated to be at the same horizontal plane as the nasal mask 7, the push block 21 will push the extrusion plate 18 to squeeze the rubber bag 17, so that the physiological saline inside the rubber bag 17 can flow into the air bag 3 through the pipe 16 to expand the air bag 3 to fix the nasogastric tube body 24. After the air bag 3 is expanded, the force will not cause the nasogastric tube body 24 to be deformed. The convex block 4 can be used to increase the friction between the nasogastric tube body 24 and the air bag 3, thereby increasing the fixing effect of the air bag 3 on the nasogastric tube body 24.

[0038] Both ends of one side of the nasal mask 7 are equipped with fixing parts, and the fixing parts include two fixing blocks 6, which are respectively fixedly connected to the two ends of one side of the nasal mask 7. A mounting groove 12 is opened inside the mounting block 9, and a spring 13 is fixedly connected to the inner wall of the mounting groove 12. One end of the spring 13 is fixedly connected to a limiting block 14. The limiting block 14 is set to an arc structure, and one end of the limiting block 14 is inserted into the limiting groove 11. When the mounting block 9 and the nasal mask 7 are rotated to the same horizontal plane, the spring 13 will push the limiting block 14 into the limiting groove 11 to limit the mounting block 9 to prevent the mounting block 9 from pulling the nasogastric tube body 24 due to accidental rotation.

[0039] Slide grooves 19 are provided on both sides of the inner wall of the cavity 15, and sliders 20 are slidably connected inside the multiple slide grooves 19. The adjacent sides of the multiple sliders 20 are fixedly connected to the two sides of the extrusion plate 18. When the push block 21 pushes the extrusion plate 18 to move inside the cavity 15, it will drive the slider 20 to move inside the slide groove 19. The slider 20 can be used to limit the extrusion plate 18 to prevent the extrusion plate 18 from tilting under the push of the push block 21.

[0040] A plurality of evenly distributed through holes 8 are provided at the top of the nasal mask 7. When the nasal mask 7 is fixed to the patient's nose, the through holes 8 can be used to allow air to flow inside the nasal mask 7, thereby preventing the nasal mask 7 from being too stuffy and causing discomfort to the patient.

[0041] A slot 22 is provided inside the nose mask 7, and a retractable belt 23 is provided inside the slot 22. The retractable belt 23 is made of elastic nylon. Both ends of the retractable belt 23 are fixedly connected to the fixing belt 10. One end of the two fixing belts 10 passes through the inner sides of the slot 22 and is fixedly connected to the Velcro 5 on both sides.

[0042] After the nasal mask 7 is fixed to the patient's nose with the tape 1, the fixing straps 10 on both sides of the nasal mask 7 can be wrapped around the back of the patient's head, and the Velcro 5 on the fixing straps 10 can be fitted together to further fix the nasal mask 7 to the patient's nose. At the same time, when the patient's head circumference is large, the fixing straps 10 on both sides can be pulled to stretch the elastic straps 23 connecting the fixing straps 10 to both sides so that the fixing straps 10 can extend out of the slots 22, thereby adapting to the head circumference of different patients.

[0043] Working principle: Insert the nasogastric tube body 24 into the patient's nasal cavity, place the nasal mask 7 on the patient's nose, and use the tape 1 to fix the nasal mask 7 to the patient's nose, wrap the fixing straps 10 on both sides of the nasal mask 7 around the back of the patient's head, and fit the Velcro 5 on the fixing straps 10 together to further fix the nasal mask 7 to the patient's nose, rotate the mounting block 9 by hand to make the fixing ring 2 bridge the outside of the nasogastric tube body 24, at this time the push block 21 will push the extrusion plate 18 to squeeze the rubber bag 17, so that the physiological saline inside the rubber bag 17 can flow into the air bag 3 through the pipe 16 to expand the air bag 3 to fix the nasogastric tube body 24.

[0044] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
