A notch for the nutrition tube 1 to enter and exit is provided on one side of the second heating sleeve 402. A pressing belt 406 is provided at the notch. One end of the pressing belt 406 is fixedly connected to the outer wall of the second heating sleeve 402. The other end of the pressing belt 406 is provided with a Velcro for being attached and connected to the outer side of the second heating sleeve 402. A sealing pad 407 for sealing and embedding in the notch is provided on the pressing belt 406.

After the nutrition tube 1 is inserted into the second heating sleeve 402, the pressing belt 406 and the sealing pad 407 can play a role in binding the nutrition tube 1, and also play a role in heat preservation to prevent the loss of heating heat.

[0048] In order to clean the inner wall of the nutrient tube 1, the spiral cleaning head structure 6 includes an inner cleaning sleeve 601 and an outer cleaning sleeve 603 arranged in inner and outer concentric circles.

Through the above-mentioned specific structural design, when the pulse flusher 10 performs pulse flushing, the water flow can impact-drive the propeller plate 604, and the rotation of the propeller plate 604 can drive the inner cleaning sleeve 601 to rotate through the bearing 602, thereby realizing the rotation of the inner cleaning sleeve 601 under the pull of the extraction rope 302. The rotation of the propeller plate 604 can change the flow direction of the water flow, and flush toward the inner wall of the pipe in multiple directions, thereby improving the flushing effect. In addition, it also moves in the pipe under the manipulation of the propeller plate 604, and when the outer cleaning sleeve 603 rotates, the cleaning bristles 605 provided on the outer wall of the outer cleaning sleeve 603 can realize the cleaning of the inner wall of the pipe, and realize the cleaning of stubborn impurities on the inner wall of the pipe.

[0049] Working principle:

[0050] Clinically, during the use of the feeding tube 1, 20-30 ml of warm water is required for pulse flushing every 4 hours, and the pipeline is also required to be pulse flushed before and after the infusion of drugs through the feeding tube 1 to prevent feeding interruption due to pipeline blockage. Specifically, the feeding tube 1 is inserted into the patient's body to provide nutrition, such as nasogastric feeding and enteral nutrition, and the pulse flusher 10 is used to flush the inner wall of the feeding tube 1;

[0051] When the pulse flusher 10 is used for flushing, the motor 306 of the pull-holding and drawing-out assembly 3 is driven to pay out the drawing-out rope 302. At this time, the spiral cleaning head structure 6 moves in the nutrient tube 1 under the impact of the pulse water flow, and the spiral cleaning head structure 6 cleans the inner wall of the nutrient tube 1. The propeller plate 604 of the spiral cleaning head structure 6 is driven to rotate under the impact of the water flow, thereby driving the outer cleaning sleeve 603 and the cleaning bristles 605 provided on the outer wall of the outer cleaning sleeve 603 to rotate, so that the cleaning bristles 605 can brush the inner wall of the nutrient tube 1 to avoid stubborn residues on the inner wall of the nutrient tube 1. After cleaning, the pull-holding and drawing-out assembly 3 can pull the spiral cleaning head structure 6 back into the first flushing tube 2.

[0052] In addition, the heating assembly 4 can heat the nutrient tube 1 and the flushing tube respectively to maintain constant temperature injection of the nutrient solution and the flushing solution, and the temperature sensor 5 can realize the temperature feedback control of the first electric heater 403 and the second electric heater 404 by the digital display control panel 7;

[0053] The heating component 4 and the pulse flusher 10 are both arranged on the first liquid guiding pipe 303. After the pulling and pumping component 3 is disassembled and separated from the first flushing tube 2 and the second flushing tube 9, the heating component 4 is disassembled and separated from the nutrition tube 1, so that the pulling and pumping component 3, the heating component 4 and the pulse flusher 10 can be recycled after disinfection and cleaning, thereby reducing the use cost.

[0054] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention.
