Through the setting of the above structure, it is convenient to put the thermal insulation cotton 6 on the surface of the gastric tube body 1. During the specific operation, the thermal insulation cotton 6 is wrapped around the surface of the gastric tube body 1, and then the first magnetic plate 61 is attached to the corresponding second magnetic plate 62 to complete the fixation of the thermal insulation cotton 6. The operation is also more convenient, and there is a certain distance between each first magnetic plate 61 and the second magnetic plate 62, so that the gastric tube body 1 can bend normally.

[0054] like Figure 1 , Figure 6 and Figure 8 As shown, a top cover 31 is threadedly sleeved on the top of each tank body 3, and each top cover 31 is connected to a handle 32, and each handle 32 is provided with a through hole 36. With the arrangement of the above structure, the top cover 31 can protect the liquid in the tank body 3 to avoid accidental leakage of the liquid. With the arrangement of the handle 32 and the through hole 36, it is not only convenient for personnel to remove the top cover 31, but also can ensure the normal flow of the liquid in the tank body 3.

[0055] like Figure 3As shown, the bottom ends of the two second hook plates 42 are elastically slidably arranged in the two first hook plates 41 respectively, which can facilitate the second hook plate 42 and the first hook plate 41 to be clamped on the guardrail of the bed, and a connecting plate 402 is fixedly connected between the two first hook plates 41, and the connecting plate 402 can ensure the stability of the clamping, and a pulling plate 44 is fixedly connected between the two second hook plates 42. When the second hook plate 42 and the first hook plate 41 need to be removed from the guardrail, it is only necessary to pull the pulling plate 44 upward to make the second hook plate 42 away from the first hook plate 41 to release the clamping of the guardrail, and the operation is also more convenient. Moreover, the heater 2 can be always clamped on the guardrail when not in use. When used subsequently, it is only necessary to put the two tank bodies 3 into the two heating chambers 21. The inner walls of the two first hook plates 41 and the two second hook plates 42 are fixedly connected with protective pads 403, and the protective pads 403 can improve the clamping stability of the second hook plate 42 and the first hook plate 41 on the guardrail.

[0056] like Figure 7 As shown, the inner wall of the guide frame 51 is slidably provided with two movable plates 50, and the two movable plates 50 are rectangular, the top ends of the two sets of movable frames 52 are respectively connected to the two ends of the two movable plates 50, a second compression spring 57 is fixedly connected between the two connecting rods 56, the bottom surfaces of the two U-shaped frames 54 are fixedly connected with a paddle plate 53, the bottom surface of the guide frame 51 is fixedly connected with two stoppers 59, and the gastric tube body 1 and the extrusion rod 58 are both located between the two stoppers 59,

[0057] like Figure 4 As shown, both sides of the two fixed frames 43 are provided with equidistantly arranged limiting grooves 40, and the interiors of the two adjustment plates 45 are provided with two opposite mounting cavities 46, and an L-shaped plate 400 and a plurality of first compression springs 48 connected to the L-shaped plate 400 are slidably arranged in each mounting cavity 46, and a limiting block 49 penetrating the adjustment plate 45 and engaging with the limiting groove 40 is fixedly connected to the bottom end of each L-shaped plate 400, and a top block 47 extending to the outside of the adjustment plate 45 is fixedly connected to the top end of each L-shaped plate 400, and a connecting member 47 is fixedly connected between the two adjustment plates 45.

[0059] Example 2

[0060] In order to increase the pressing area of ​​the gastric tube body 1, the following improvements are made on the basis of Example 1:

[0061] See also Fig.11 As shown, the left and right sides of the squeezing rod 58 are connected to the top plate 501 through the torsion spring rod, and the top of each top plate 501 is rotatably provided with a roller 502, and each roller 502 is provided with a plane section. Through the arrangement of the top plate 501 and the roller 502, when the squeezing rod 58 rises to squeeze the gastric tube body 1, the two rollers 502 can roll on the gastric tube body 1, and when the plane section on the roller 502 contacts the gastric tube body 1, it will not be able to roll, so that the plane section on the roller 502 squeezes the gastric tube body 1 to increase the pressing area of ​​the gastric tube body 1 and ensure the sealing of the gastric tube body 1. Specifically, when in use, the gastric tube body 1 is first passed through a group of guide rollers 55, and then passed through the top of the two rollers 502, and at this time, the plane sections of the two rollers 502 will be away from the gastric tube body 1, so that the two rollers 502 position the gastric tube body 1 at the bottom of the guide frame 51, and then the gastric tube body 1 is passed through another group of guide rollers 55.

[0062] According to the working principle of the present invention, the heater 2 is clamped on the guardrail of the bed through the first hook plate 41 and the second hook plate 42, and then the personnel pinch the two sets of top blocks 47 to pull the heater 2 and the adjustment plate 45 upward to adjust the height of the heater 2, which is also convenient for the personnel to take the liquid pump 4 for operation. After adjusting the height of the heater 2, the top block 47 can be loosened to allow the limit block 49 to automatically position the adjustment plate 45 to ensure the stability of the heater 2, and then water and nutrient solution are respectively poured into the two tanks 3, and then The top cover 31 seals the tank body 3 to prevent dust from entering. Then, the two tank bodies 3 are placed in the two heating chambers 21, and the power of the heater 2 is turned on to start heating the liquid in the tank body 3. After heating to the specified temperature, the valve 35 on the first delivery tube 33 is opened and the valve 35 on the second delivery tube 34 is closed, so that the nutrient solution first enters the gastric tube body 1, and the injection cylinder 4 is used to continuously inject the nutrient solution into the patient's body through the gastric tube body 1. In this process, the heat-insulating cotton 6 can keep the nutrient solution in the process of being transported warm. To avoid excessive temperature loss, the temperature measuring patch 7 can measure the temperature of the nutrient solution in the gastric tube body 1, so as to facilitate timely control of the heating temperature of the heater 2. When the nutrient solution is injected, the valve 35 on the first delivery tube 33 is closed and the valve 35 on the second delivery tube 34 is opened, and then the injection cylinder 4 is pushed and pulled to flow water into the gastric tube body 1 through the second delivery tube 34, so as to flush the residual nutrient solution in the gastric tube body 1. At this time, the water is also heated, so there is no need for personnel to prepare warm water in advance, and there is no need to replace the syringe. The operation is more convenient. When all the processes are completed, pinch the two paddles 53 together so that the squeezing rod 58 squeezes the stomach tube body 1 onto the guide frame 51 to prevent outside air from entering the stomach tube body 1. The liquid-injecting cylinder 4 and the first delivery tube 33 can be removed from the stomach tube body 1, and the corresponding sealing plugs can be used to seal the liquid inlet and the air inlet pipe 8 of the stomach tube body 1.
