DETAILED DESCRIPTION

[0020] In order to further understand the invention content, characteristics and effects of the utility model, the following examples are used for detailed description.

[0021] Please refer to Figure 1 and Figure 2 The enteral nutrition infusion device of the utility model includes base 1, and a wall breaking assembly and an infusion assembly are arranged on the base 1. The base 1 is used for supporting the wall breaking assembly and the infusion assembly, and on the other hand, a control circuit board is arranged in the base 1, and a power supply interface is arranged on the back of the base 1, and power supply is realized by using a power cable. The wall breaking assembly is used for preparing the nutrient solution, and the operation principle of the wall breaking machine is adopted, and the raw materials of the nutrient solution are stirred and crushed to form a fluid under the action of the wall breaking assembly. Of course, it is also conceivable that the prepared nutrient solution can be directly sent into the interior of the wall breaking assembly. The infusion assembly is used for injecting the nutrient solution into the gastrointestinal tract of the patient in an active infusion mode.

[0022] For example, Figure 1As shown in the figure, the cell wall breaking assembly comprises a housing 2, the bottom of which is fixedly connected with the top of the base 1, and a detachable cell wall breaking kettle 12 is arranged on the housing 2, and the raw materials of the nutrient solution or the prepared nutrient solution are arranged in the cell wall breaking kettle 12. A handle 9 is arranged on the side of the cell wall breaking kettle 12 to facilitate the operation of the cell wall breaking kettle 12, a buckle 10 is arranged on the top of the cell wall breaking kettle 12, and a pouring opening is arranged on the side of the top of the cell wall breaking kettle 12 to facilitate the pouring of the residual materials in the cell wall breaking kettle 12. Since the cell wall breaking kettle 12 can be taken off the housing 2 as a whole, it is easier to perform operations such as adding raw materials of the nutrient solution / nutrient solution and cleaning and disinfecting.

[0023] A cell wall breaking motor 7 is arranged in the housing 2, a cell wall breaking impeller 11 is arranged in the middle of the bottom wall 13 of the cell wall breaking kettle 12, a sealing type shaft seat is arranged in the middle of the bottom wall 13, and the rotating shaft of the cell wall breaking impeller 11 is arranged in the sealing type shaft seat, and the cell wall breaking motor 7 is connected with the control circuit board in the base 1 through a cable. When the cell wall breaking kettle 12 is placed on the housing 2, the lower end of the rotating shaft of the cell wall breaking impeller 11 is connected with the upper end of the output shaft of the cell wall breaking motor 7 through a shaft coupling 5, that is, when the cell wall breaking kettle 12 is stably placed on the housing 2, the cell wall breaking impeller 11 can be connected with the cell wall breaking motor 7 in power.

[0024] In the embodiment, the shaft coupling 5 is fixedly arranged on the lower end of the rotating shaft of the cell wall breaking impeller 11, a square shaft hole is arranged in the middle of the bottom of the shaft coupling 5, the upper end of the output shaft of the cell wall breaking motor 7 is a square shaft, and when the cell wall breaking kettle 12 is placed on the housing 2, the square shaft of the cell wall breaking motor 7 is inserted into the square shaft hole of the shaft coupling 5, so that the output shaft of the cell wall breaking motor 7 is combined with the rotating shaft of the cell wall breaking impeller 11 as a whole.

[0025] In the embodiment, a plurality of positioning and combining assemblies 4 are arranged between the bottom wall 13 of the cell wall breaking kettle 12 and the top of the housing 2, each of the positioning and combining assemblies 4 comprises a sleeve arranged on the bottom wall 13 and a stand arranged at a corresponding position on the top of the housing 2, and when the cell wall breaking kettle 12 is placed on the housing 2, each of the stands is inserted into the corresponding sleeve. The positioning and combining assemblies 4 have two functions: one function is to position the cell wall breaking kettle 12, so that the cell wall breaking kettle 12 can be placed at the correct position, and the output shaft of the cell wall breaking motor 7 can be smoothly combined with the rotating shaft of the cell wall breaking impeller 11; the other function is to combine the cell wall breaking kettle 12 with the housing 2 as a whole, so that the excessive shaking of the cell wall breaking kettle 12 caused by vibration can be reduced when the cell wall breaking impeller 11 is running.

[0026] A discharge connector 14 is arranged on the bottom of the side wall of the cell wall breaking kettle 12 and penetrates the inner cavity, and the fluid nutrient solution in the cell wall breaking kettle 12 is sucked out through the discharge connector 14.

[0027] Please refer to Figure 1 and Figure 2 It can be seen that

[0028] The perfusion assembly comprises a support plate 17, the bottom of which is fixedly connected with the base 1. A perfusion roller 16 and a perfusion motor 24 for driving the perfusion roller 16 to rotate are installed on the support plate 17. The perfusion motor 24 drives the perfusion roller 16 to rotate at a uniform and slow speed. As shown in the figure, the perfusion motor 24 is fixedly installed on the back of the support plate 17, and the perfusion roller 16 is located on the front of the support plate 17. The perfusion roller 16 comprises a roller base, and a plurality of cylindrical independent roller shafts are installed on the roller base and are arranged at equal angles along the circumferential direction. The perfusion motor 24 is connected with the control circuit board in the base 1 through a cable.

[0029] A supporting arm 20 is arranged below the perfusion roller 16, and a perfusion hose 15 is arranged between the supporting arm 20 and the perfusion roller 16. The end of the perfusion hose 15 is connected with the discharge connector 14. As shown in the figure, the main part of the supporting arm 20 is V-shaped, so that the middle part of the perfusion hose 15 is wrapped around the lower part of the perfusion roller 16. During the rotation of the perfusion roller 16, the independent roller shafts on the perfusion roller 16 are sequentially pressed on the perfusion hose 15 and are shifted along the circumferential direction with the rotation of the perfusion roller 16. Thus, the fluid nutrient liquid in the perfusion hose 15 is forced to flow along the direction of the perfusion hose 15. A high-pressure area is formed at the rear part of the perfusion hose 15, and the pressurized nutrient liquid can more smoothly enter the nasogastric tube worn by the patient and further enter the gastrointestinal tract. A low-pressure area is formed at the front part of the perfusion hose 15, so as to achieve the effect of sucking the nutrient liquid in the jug through the discharge connector 14.

[0030] In this embodiment, the supporting arm 20 is hingedly connected with the support plate 17, and a connecting arm 18 with a spring is also hingedly installed on the support plate 17. The end of the supporting arm 20 is provided with a notch, and the middle part of the connecting arm 18 is located in the notch. The spring provides the supporting arm 20 with a buffer elastic force.

[0031] The foregoing structure has the advantages that: by swinging the connecting arm 18 outward, the middle part of the connecting arm 18 can be disconnected with the end notch of the supporting arm 20. Thus, the supporting arm 20 can rotate around the hinge shaft between the supporting arm 20 and the support plate 17 as the center. When the supporting arm 20 swings downward, the perfusion hose 15 is released, so that the perfusion hose 15 can be replaced and the replacement operation is convenient. The perfusion hose 15 can be designed as a consumable, which is taken off and discarded after single use. On the other hand, since the spring is arranged on the connecting arm 18, the supporting arm 20 is not rigidly installed, but can be elastically and slightly swung up and down.

[0032] A heating element 19 is also installed in the middle of the support arm 20. The heating element 19 is used to heat the infusion hose 15 above and the nutrient solution inside the hose. The heating element 19 is a flat electric heating block, and a mounting groove is provided on the inner side of the middle of the support arm 20, with the electric heating block located in the mounting groove. The heating element 19 is connected to the control circuit board in the base 1 via a cable.

[0033] In this embodiment, a support arm 22 is also installed at the bottom back of the support plate 17. An elastic base 21 is installed at the outer end of the support arm 22. A vertical through-hole is provided on the elastic base 21, and an irrigation tube 23 is inserted into the through-hole. The end of the irrigation tubing 15 is connected to the upper end of the irrigation tube 23, and the patient's irrigation tube (i.e., nasogastric tube) is connected to the lower end of the irrigation tube 23. The purpose of setting the irrigation tube 23 is to improve the convenience of docking between the irrigation tubing 15 and the patient's irrigation tube. Specifically, the elastic base 21 can be a rubber block with a through-hole in the middle, and the irrigation tube 23 is a rigid plastic tube made of medical material. It is designed as a consumable and is removed from the elastic base 21 after a single use and disposed of.

[0034] In this embodiment, hose clamps are provided on the top and outer sides of the support plate 17, and the injection hoses 15 on both sides of the injection roller 16 are respectively embedded in these two hose clamps. The purpose of providing these two hose clamps is to limit the posture of the middle part of the injection hose 15, and to prevent the injection hose 15 from being pulled and shifting or swinging during the operation of the injection roller 16.

[0035] like Figure 1 As shown, a display screen 6, a blending button 3, and an infusion speed control button 8 are installed on the outer casing 2 of the blending assembly. These components are connected to a control circuit board inside the base 1 via cables. The display screen 6 displays information such as the infusion speed of the nutrient solution and the set infusion time interval. The blending button 3 is used to manually activate the blending function after the nutrient solution is added to the container. The infusion speed control button 8 adjusts the rotation speed of the infusion motor 24, thus regulating the infusion speed of the nutrient solution.
