[0031] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0032] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model discloses a bionic digestive system for infants and young children, including a gastrointestinal model, comprising,

[0033] Base 1, base 1 is set horizontally;

[0034] The first rotating mechanism 2 includes a first rotating seat 21 that rotates in a first plane perpendicular to the base 1, and the first rotating seat 21 is connected to a first driving source 22 for driving its rotation.

[0035] The second rotating mechanism 3 includes a second rotating seat 31, which rotates in a second plane that is perpendicular to both the base 1 and the first plane. The second rotating seat 31 is connected to a second driving source 32 for driving its rotation.

[0036] The reaction chamber 4 is connected to the second rotating seat 31, and the gastrointestinal model is placed in the reaction chamber 4.

[0037] The digestive fluid assembly 5 includes an acid liquid cylinder 51, an alkali liquid cylinder 52, a gastric liquid cylinder 53, and an intestinal liquid cylinder 54, which are respectively connected to the reaction chamber 4. The acid liquid cylinder 51, alkali liquid cylinder 52, gastric liquid cylinder 53, and intestinal liquid cylinder 54 are respectively connected to the gastrointestinal model A, and the acid liquid cylinder 51, alkali liquid cylinder 52, gastric liquid cylinder 53, and intestinal liquid cylinder 54 are respectively connected to a first injection pump 55, a second injection pump 56, a third injection pump 57, and a fourth injection pump 58.

[0038] Specifically, through the cooperation of the first rotating mechanism 2 and the second rotating mechanism 3, the reaction chamber 4 and the gastrointestinal model set inside it can be rotated to different angles and postures (simulating the upright, side-lying, or lying-down positions of a person), thereby simulating the state of infants and young children in such conditions. Figure 6 and Figure 7 The system simulates the complex feeding and digestion processes under various conditions. It includes an acid solution tank 51, an alkali solution tank 52, a gastric juice tank 53, and an intestinal juice tank 54, which, along with a first injection pump 55, a second injection pump 56, a third injection pump 57, and a fourth injection pump 58, form the entire digestive fluid system. This system can simulate the digestion process under different digestive fluid conditions. It is conceivable that both the first rotating mechanism 2 and the second rotating mechanism 3 are electrically controlled, achieving automatic adjustment of the rotation angle through the cooperation of the drive structure and the control unit 6. Compared to manual adjustment mechanisms, this offers higher adjustment efficiency and accuracy, which is beneficial to the accuracy of experimental results.

[0039] Specifically, such as Figure 6 The first rotating mechanism 2 shown can drive the second rotating mechanism 3 and the reaction box 4 connected to the second rotating mechanism 3 and the gastrointestinal model inside it to rotate left and right, that is, to simulate the human body from an upright to a side-lying position; as shown Figure 7 As shown, the second rotating mechanism can simultaneously drive the reaction chamber 4 and the gastrointestinal model inside to rotate back and forth, simulating the human body lying down or prone position. The two rotating mechanisms work together to simulate the eating and digestion process in various positions.

[0040] Specifically, the injection volume and injection speed of each reaction solution can be precisely adjusted by the first injection pump 55, the second injection pump 56, the third injection pump 57 and the fourth injection pump 58, which are respectively connected to the acid solution cylinder 51, the alkali solution cylinder 52, the gastric solution cylinder 53 and the intestinal solution cylinder 54, thereby simulating the digestion process under various digestive fluid secretion states and ensuring the accuracy of the experimental results.

[0041] Furthermore, the system includes a control unit 6, which is connected to the first drive source 22, the second drive source 32, the first injection pump 55, the second injection pump 56, the third injection pump 57, the fourth injection pump 58, and the gastrointestinal model. Specifically, the control unit 6 is connected to the first drive source 22, the second drive source 32, the first injection pump 55, the second injection pump 56, the third injection pump 57, the fourth injection pump 58, the gastrointestinal model, the first position sensor 24, and the second position sensor 34. The control unit 6 serves as the control core of the entire system to control the operation of each component.

[0042] Furthermore, acid cylinder 51 and gastric fluid cylinder 53 are connected to a first input tube via a T-connector to the digestive chamber of the gastrointestinal model, while alkali cylinder 52 and intestinal fluid cylinder 54 are connected to a second input tube via another T-connector to the digestive chamber of the gastrointestinal model. Specifically, the gastrointestinal model is also equipped with a pH meter for detecting the pH of the reaction solution within the digestive chamber, further ensuring the accuracy of the reaction process and results.

[0043] Furthermore, the acid liquid cylinder 51, the alkali liquid cylinder 52, the gastric liquid cylinder 53, and the intestinal liquid cylinder 54 are arranged on the same side of the reaction chamber 4.

[0044] Furthermore, the side of the reaction chamber 4 has through holes corresponding to the positions of the first and second input pipes. A mounting plate is installed on the through hole, and a heating plate 7 is mounted on the mounting plate. Specifically, the acid cylinder 51, alkali cylinder 52, gastric fluid cylinder 53, and intestinal fluid cylinder 54 are located on the same side of the reaction chamber 4. This places the first and second input pipes on the same side inside the reaction chamber 4. By installing a heating plate 7 on the side of the reaction chamber 4, the reaction solution passing through the first and second input pipes can be heated to a certain extent, ensuring the smooth progress of the reaction process while reducing the number of heating plates 7, thereby reducing the complexity of the equipment and manufacturing costs.

[0045] Furthermore, the first rotating mechanism 2 includes two support blocks symmetrically arranged on the base 1, and a bearing seat is connected to each of the two support blocks. The two ends of the first rotating seat 21 are provided with coaxial rotating shafts, and the two rotating shafts are rotatably connected to the two bearing seats through bearings. One of the rotating shafts is connected to the first driving source 22.

[0046] Reference Figure 2 and Figure 3As shown, further, the first drive source 22 is mounted on the base 1 via a connecting plate. A first sensing plate 23 is vertically connected to the free end of the rotating shaft connected to the first drive source 22, and multiple first position sensors 24 located on the movement path of the first sensing plate 23 are provided on the connecting plate. Specifically, both the first drive source 22 and the second drive source 32 can be geared motors. During the process of the first drive source 22 driving the rotating shaft (first rotating seat 21) to rotate, the first sensing plate 23 vertically connected to the free end of one of the rotating shafts will rotate with this rotating shaft. When the first sensing plate 23 rotates to a certain angle, it will be sensed by the first position sensor 24 at the corresponding position, thereby determining whether the rotation angle of the rotating shaft is in place.

[0047] Furthermore, the second rotating mechanism 3 includes a support shaft connected to the first rotating seat 21. The second rotating seat 31 is rotatably connected to the support shaft. A second sensing plate 33 is mounted on one side of the second rotating seat 31, and multiple second position sensors 34 located on the movement path of the second sensing plate 33 are provided on the first rotating seat 21. Specifically, during the rotation of the second rotating seat 31, the second sensing plate 33 rotates with the second rotating seat 31. The rotation angle and position of the second rotating seat 31 can be confirmed by the multiple second position sensors 34 located on the rotation path of the second sensing plate 33, ensuring the accuracy of the experimental process and results.

[0048] Furthermore, the side of the reaction chamber 4 is provided with a ventilation opening that connects to its interior, and an air circulation fan 8 is installed on the ventilation opening. The temperature inside the reaction chamber 4 can be regulated by the air circulation fan 8.

[0049] Furthermore, the bottom of the reaction chamber 4 has at least one mounting hole communicating with its interior, and a heating lamp 9 is installed in the mounting hole. Specifically, by setting the heating lamp 9 at the bottom of the reaction chamber 4, the internal temperature of the reaction chamber 4 is adjusted, thereby simulating the temperature environment inside the human body, which is beneficial to the accuracy of the experimental results.

[0050] like Figure 5 As shown, the gastrointestinal model further includes a bionic stomach model A5, with an esophagus A3 connected to the input end of the bionic stomach model A5. An injection device A1 is provided at the end of the esophagus away from the bionic stomach model, and an upper esophageal clamp A2 and a lower esophageal clamp A4 are respectively provided at both ends of the esophagus. The bionic stomach model A5 is connected to a gastric peristalsis device A6, and a bionic duodenal model A8 is connected to the output end of the bionic stomach model A5. A pyloric clamp A7 is also provided between the bionic stomach model A5 and the duodenal model A8. At the same time, a duodenal compression device A9 and a duodenal clamp A10 are respectively provided on the duodenal model A8.

[0051] Experimental procedure:

[0052] The first rotating mechanism 2 and the second rotating mechanism 3 are reset by the control unit 6; then, all components are installed and the digestive fluid and digestive chamber are preheated; then, the experimental sample is placed in the digestive chamber and the parameters such as the secretion rate of each digestive fluid, the angle and posture of the gastrointestinal model, and the peristaltic frequency of the gastrointestinal model are set to start the simulated digestion; after the experiment is completed, the two rotating mechanisms are reset, and then the gastrointestinal model, the reaction fluid input tubes (i.e., the first input tube and the second input tube), the pH meter and other components are cleaned, and the experimental data are processed, and the experiment is completed.

[0053] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description.
