[0024] Please refer to the attached Figure 1 - attached Figure 5 , a special nasogastric feeding device for patient nutritional support, including a support column 1 and a nutrient solution bag 13. A storage rack 4 with an L-shaped structure is fixedly installed at the top of the support column 1. A chute 7 is opened on one side of the storage rack 4. A lifting plate 6 is slidably installed in the chute 7. A circular convex block 22 is fixedly installed on one side of the top of the lifting plate 6. A bracket 11 with a U-shaped structure is provided on one side of the top of the lifting plate 6. A transfer block is provided on one side of the bracket 11. A rotation groove 29 adapted to the circular convex block 22 is opened at the bottom of the transfer block. A hook 12 is fixedly installed at the top inside the bracket 11. A device hole 21 penetrating its surface is opened at the top of the storage rack 4. A heating cylinder 16 is rotatably installed in the device hole 21. A tip joint for inserting the nutrient solution bag 13 is provided at the top of the heating cylinder 16. A branch pipe 27 is provided on one side of the heating cylinder 16. Two first limit blocks 26 are symmetrically arranged on the surface of the heating cylinder 16. A first limit groove 28 adapted to the heating cylinder 16 is opened at one side of the bottom of the bracket 11.

[0025] During use, by setting the bracket 11 and the heating cylinder 16, during the use process, the nutrient solution bag 13 is hung on the hook 12 at the top of the bracket, the tip joint at the top of the heating cylinder 16 is inserted into the bottom of the nutrient solution bag 13, so that the nutrient solution is conveyed into the heating cylinder 16. As the bracket 11 makes a reciprocating rotation at a certain angle, the nutrient solution bag 13 and the heating cylinder 16 can be driven to make a reciprocating rotation, thereby making the nutrient solution in the nutrient solution bag 13 and the heating cylinder 16 in a shaking state, so that various nutrients in the nutrient solution bag 13 and the heating cylinder 16 are fully mixed, avoiding stratification and precipitation, and improving the smoothness inside the pipeline;

[0026] A branch pipe 17 is provided, and other nutrients or medicines required by doctors' orders can be added to the heating tube 16 during the use of the device. As the heating tube 16 is shaken, the added nutrients or medicines are quickly dissolved and mixed evenly. A detachable dust cap is provided at the end of the branch pipe 17, which improves the practicability of the device.

[0027] In this embodiment, a through hole is provided on the top of the adapter block, which passes through the surface of the adapter block. Two second limit blocks 30 are provided in the through hole. A rubber plug 25 is fixedly embedded in the middle of the bottom of the heating tube 16. A groove 24 is provided at the bottom of the heating tube 16. An electric heating ring 23 is fixedly installed in the groove 24. The interior of the heating tube 16 is a hollow structure. A liquid inlet hole is provided on the surface of the tip joint. A fixing plate 8 is fixedly installed on one side of the rack 4. A screw rod 10 and a main shaft 14 are rotatably installed at the bottom of the fixing plate 8. One end of the screw rod 10 passes through the outer surface of the lifting plate 6 and is threadedly connected thereto. A circular hole is provided on one side of the top of the lifting plate 6 for avoiding the main shaft 14, and two second limit grooves adapted to the second limit block 30 are provided on the surface of the main shaft 14. The adapter block is slidably sleeved on the surface of the main shaft 14 through the second limit block 30, and the bottom end of the screw rod 10 is rotatably installed with the top of the rack 4. A servo motor 15 is fixedly installed on the top of the rack 4, and the output end of the servo motor 15 is fixedly installed with the rotation center of the bottom end of the main shaft 14. A hand wheel 9 is rotatably installed on the top of the fixed plate 8, and the bottom of the hand wheel 9 is fixedly installed with the rotation center of the top of the screw rod 10 through a connecting shaft.

[0028] When in use, the servo motor 15 is set to reciprocate and rotate at a certain angle, and the bracket 11 is slidably sleeved on the surface of the main shaft 14 through the adapter block. The rotation of the main shaft 14 drives the bracket 11 to reciprocate and rotate. When encountering nutrient solution bags 13 of different specifications, to avoid the spacing between the nutrient solution bag 13 and the heating cylinder 16 being too small or too large, the hand wheel 9 can be rotated, and the hand wheel 9 drives the screw rod 10 to rotate, thereby driving the lifting plate 6 to adjust the height, and then driving the bracket 11 to adjust the height, so that after the nutrient solution bag 13 is connected to the heating cylinder 16, its top can be normally hung on the hook 12, thereby improving the practicality of the device;

[0029] A heating cylinder 16 is provided. When the temperature of the nutrient solution in the nutrient solution bag 13 is low, the inner wall of the heating cylinder 16 can be heated by starting the motor heat ring 23, thereby increasing the temperature of the nutrient solution entering the heating cylinder 16, thereby preventing the cold nutrient solution from entering the stomach and intestines and causing discomfort, thereby improving the patient's comfort during the eating process.

[0030] In this embodiment, a Mauffy's dropper 17 is embedded at the bottom of the heating tube 16, and an adapter for connecting a gastric tube is provided at the bottom end of the Mauffy's dropper 17. A fixing block 19 is fixedly installed on one side of the pillar 1, and two limiting holes are provided on one side of the fixing block 19. The long axis and the short axis are slidably installed in the two limiting holes respectively, and a spring 20 is fixedly installed on one end of the long axis, and the other end of the spring 20 is fixedly installed on the fixing block 19. A clamping block 18 is fixedly installed on the other end of the long axis and the short axis, and an arc-shaped card groove compatible with the Mauffy's dropper 17 is provided on one side adjacent to the clamping block 18 and the fixing block 19. A battery 5 is fixedly installed on one side of the top of the shelf 4, a controller 3 is fixedly installed on one side of the pillar 1, and a plurality of self-locking universal wheels 2 are installed at the bottom of the pillar 1.

[0031] When in use, the Mouphy's dropper 17 is inserted into the heating tube 16 through the rubber plug 25 at the bottom of the heating tube 16, and then the other end is connected to the gastric tube through the adapter, and the clamping block 18 is pulled to clamp the tube body of the Mouphy's dropper 17 in the arc-shaped groove on one side of the fixing block 19, so as to avoid the Mouphy's dropper 17 from shaking violently due to the reciprocating rotation of the heating tube 16, thereby improving the stability of the device during use. The controller 3 is provided with a liquid crystal display screen, which can display the temperature in the heating tube 16 in real time, so that the staff or family members can adjust the temperature in time. The self-locking universal wheel 2 is provided, so that the device can be moved as needed, and then the universal wheel is locked, thereby improving the convenience of the device during use.

[0032] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
