The inner tube 1 and the upper surface of the outer tube 3 are fixedly installed with an external threaded sleeve 6, and the external threaded sleeve 6 is connected to the inner tube 1, and the external threaded sleeve 6 is internally threadedly connected to the internal threaded sleeve 7. The upper surface of the internal threaded sleeve 7 is fixedly installed with a cylinder 8, and the cylinder 8 is connected to the internal threaded sleeve 7. The filter screen plate 9 is installed on the lower inner wall of the cylinder 8, and the upper surface of the cylinder 8 is threadedly installed with a sealing cover 10. A feeding pipe 11 is embedded in the sealing cover 10 near the left position, and a crushing mechanism 12 is provided in the middle position of the sealing cover 10. A prompt mechanism 13 is provided on the right wall of the cylinder 8.

[0021] Specifically, the lower surface of the discharge head 2 is an arc-shaped structure.

[0022] In this embodiment, the discharge head 2 is inserted into the intestine more smoothly and is less likely to cause damage to the intestine, and the discharge head 2 is made of rubber material.

[0023] Specifically, the organizing mechanism 5 includes a pull rope 501, a circular ring 502, a movable ring 503 and a through hole 504. The pull rope 501 is rectangular and has four pieces. The circular rings 502 are evenly arranged on the pull rope 501. The circular rings 502 are movably installed between the outer surface of the inner tube 1 and the inner wall of the outer tube 3. The upper ends of the pull ropes 501 are fixedly connected to the inner wall of the movable ring 503. The movable ring 503 is movably sleeved on the outside of the outer tube 3. A through hole 504 is provided on the side wall of the outer tube 3 near the position of the external threaded sleeve 6 and corresponding to the pull rope 501.

[0024] In this embodiment, the circular ring 502 supports the inner tube 1 and the outer tube 3 to prevent the inner tube 1 and the outer tube 3 from bending and folding. When blockage occurs, the movable ring 503 pulls the pull rope 501 outward, so that the pull rope 501 drives the circular ring 502 to move upward. The circular ring 502 enables the bent part of the inner tube 1 and the outer tube 3 to be unfolded to ensure the flow of food. At the same time, the pull rope 501 pulls open the tension spring 4. When the bent part of the inner tube 1 and the outer tube 3 can be unfolded, the tension spring 4 resets the circular ring 502 through the pull rope 501, and the inner tube 1 and the outer tube 3 can be further arranged.

[0025] Specifically, the crushing mechanism 12 includes a rotating shaft 121, a mechanical seal 122, a handle 123 and a crushing blade 124. The rotating shaft 121 is installed on the sealing cover 10 through the mechanical seal 122, and the rotating shaft 121 is inserted into the cylinder 8. The handle 123 is fixedly installed on the upper surface of the rotating shaft 121, and the crushing blade 124 is installed near the lower side of the rotating shaft 121.

[0026] In this embodiment, the handle 123 drives the rotating shaft 121 to rotate in the mechanical seal 122, so that the rotating shaft 121 drives the crushing blade 124 to rotate, and the crushing blade 124 crushes the food with a larger diameter filtered out by the filter plate 9.

[0027] Specifically, the length of the crushing blade 124 matches the inner diameter of the cylinder 8 , and the lower surface of the crushing blade 124 is movably fitted to the upper surface of the filter screen plate 9 .

[0028] In this embodiment, the crushing blade 124 can completely crush the food in the cylinder 8, and at the same time, the lower surface of the crushing blade 124 cleans the upper surface of the filter plate 9 to prevent the filter plate 9 from being blocked.

[0029] Specifically, the prompt mechanism 13 includes a control box 131, a temperature probe 132, a buzzer 133 and a switch button 134. The control box 131 is installed on the right side of the cylinder 8. The temperature probe 132 is sealed and embedded on the left side wall of the control box 131 and the right side wall of the cylinder 8. The buzzer 133 is embedded on the front and rear side walls of the control box 131. The switch button 134 is provided on the upper surface of the control box 131.

[0030] In this embodiment, the switch button 134 enables the battery in the control box 131 to provide power to the controller. The controller enables the temperature probe 132 to detect the temperature of the food in the cylinder 8 and feeds back the collected food temperature information to the controller. After processing by the information processing module, it is compared with the set value. When the temperature of the food is greater than or less than the set value, the controller causes the buzzer 133 to alarm to avoid secondary injury or discomfort to the patient.

[0031] When in use, the discharge head 2 is inserted into the stomach. During the insertion process, the inner tube 1 and the outer tube 3 are supported by the circular ring 502 in the arranging mechanism 5 to prevent the inner tube 1 and the outer tube 3 from bending and folding. The food flows into the cylinder 8 through the feeding tube 11. The switch button 134 in the prompting mechanism 13 enables the battery in the control box 131 to provide power to the controller. The controller enables the temperature probe 132 to detect the temperature of the food in the cylinder 8 and feeds back the collected temperature information of the food to the controller. After being processed by the information processing module, it is compared with the set value. When the temperature of the food is greater than or less than the set value, the controller makes the buzzer 133 alarm to avoid secondary injury or discomfort to the patient. The food flows into the inner tube 1 through the filter screen 9. The filter screen 9 filters the larger diameter food and passes through The handle 123 in the crushing mechanism 12 drives the rotating shaft 121 to rotate in the mechanical seal 122, so that the rotating shaft 121 drives the crushing blade 124 to rotate, and the crushing blade 124 crushes the food with larger diameter filtered out by the filter plate 9, and the food flows through the inner tube 1 and the discharge head 2. When blockage occurs, it means that the inner tube 1 and the outer tube 3 may be completely folded, so that the movable ring 503 pulls the pull rope 501 to move outward, and the pull rope 501 drives the circular ring 502 to move upward. The circular ring 502 enables the folded part of the inner tube 1 and the outer tube 3 to be unfolded to ensure the flow of food. At the same time, the pull rope 501 pulls the tension spring 4. When the folded part of the inner tube 1 and the outer tube 3 can be unfolded, the tension spring 4 resets the circular ring 502 through the pull rope 501, and the inner tube 1 and the outer tube 3 can be further sorted.

[0032] In summary, the anti-blocking gastrointestinal nutrition tube reduces the possibility of bending and folding of the gastrointestinal nutrition tube, and can tidy up the bent and folded parts of the gastrointestinal nutrition tube to ensure the flow of food, while increasing the filtering and crushing function of the added food to ensure that the food will not block the gastrointestinal nutrition tube, and at the same time detect the temperature of the added food to ensure that the food temperature is appropriate and safe to use.
