Description

Technical Field

[0001] This utility model belongs to the field of teaching aids technology, and in particular relates to a blood glucose regulation demonstration device. Background Technology

[0002] Many teaching aids are used in biology education, but their functions are singular, designed only for a single, independent knowledge point, lacking systematic and spatial understanding. The regulation of blood glucose balance in the human body involves multiple organs and various regulatory mechanisms. In daily learning, students rarely see how these organs work together to complete this process. Therefore, students often find it difficult to understand the blood glucose regulation process due to a lack of concrete spatial and systematic understanding.

[0003] Utility model patent CN209183067U discloses a blood glucose balance demonstration device, which includes a rectangular template on which a simplified blood circulation path is drawn, and various organ and blood vessel areas are set up to demonstrate the blood glucose regulation process. However, during the demonstration, the magnetic ball needs to be constantly picked up and placed and its position changed. The demonstration of blood glucose regulation requires continuous manipulation of the magnetic ball, making the demonstration process quite complex.

[0004] A utility model with publication number CN216287244U discloses a real-time blood glucose regulation model, which includes multiple pancreatic A cells, pancreatic B cells, and capillary modules. It simulates changes in blood glucose levels by using three switches to control different light strips and a running light display. However, during the demonstration, the switches need to be constantly operated to control the position of the running light display to demonstrate blood glucose regulation, making the operation process complex. Furthermore, the demonstration cannot establish the spatial connections between human organs, resulting in a lack of three-dimensionality. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Understandably, the organs primarily involved in blood sugar regulation include the hypothalamus in the brain, pancreatic A cells and B cells in the pancreas, and the liver, skeletal muscle, and fat, which produce biochemical reactions regulated by insulin and glucagon, respectively. Furthermore, during eating, the mouth, esophagus, stomach, and small intestine are all involved in blood sugar regulation. During eating, food enters the esophagus, reaches the stomach, and finally enters the small intestine. After absorption in the small intestine, blood sugar levels rise.

[0028] like Figure 1 and Figure 2 As shown, this embodiment provides a blood glucose regulation demonstration device, including:

[0029] The multi-colored balls 1 represent glucose, neurotransmitters, insulin, and glucagon, respectively.

[0030] For example, the multi-colored beads 1 include yellow beads, green beads, red beads, dark blue beads and light blue beads, wherein the yellow beads represent glucose, the light blue beads and dark blue beads represent neurotransmitters in different states, the red beads represent insulin, and the green beads represent glucagon.

[0031] Multiple sensor-activated building blocks 2 are used to represent the mouth, stomach, hypothalamus, pancreas, liver, skeletal muscle, and fat, such as Figure 3 As shown, each sensor block 2 has a ball bearing spiral slide track 21 inside, and a pressure-sensitive button 22 is provided on the surface of the spiral slide track 21.

[0032] Multiple connecting tracks 3 are used to connect the various sensor blocks 2, which represent the esophagus, small intestine, blood vessels, and nerves.

[0033] Multiple labels 4 are used to attach to each sensor block 2 and each connecting track 3 to label the oral cavity, stomach, hypothalamus, pancreas, liver, skeletal muscle, fat, esophagus, small intestine, blood vessels, and nerves.

[0034] For example, each inductive block 2 is provided with an LED light strip 23; wherein the inductive block 201 representing the oral cavity and stomach is provided with a single-color LED light strip, and the inductive block representing the hypothalamus, pancreas, liver, skeletal muscle and fat is provided with a dual-color LED light strip, and the dual-color LED light strip is electrically connected to a rotary switch 24, which can be provided on the inductive block 2.

[0035] All the sensor-activated building blocks 2 and connecting tracks 3 are interlocked and assembled according to the positional relationships of human organs to form digestive and absorption pathways and blood sugar regulation pathways; for example Figure 1As shown, the digestive and absorptive pathway is formed by interlocking and splicing a sensor block 201 representing the oral cavity, a connecting track 301 representing the esophagus, a sensor block 202 representing the stomach, a connecting track 302 representing the small intestine, and a connecting track 303 representing blood vessels.

[0036] like Figure 2 As shown, in the blood glucose regulation pathway, the sensor block 206 representing the hypothalamus is connected to the sensor block 203 representing the pancreas via a connecting track 304 representing a nerve; the sensor block 203 representing the pancreas is connected to the sensor block 207 representing skeletal muscle, the sensor block 204 representing the liver, and the sensor block 205 representing fat via three connecting tracks 303 representing blood vessels.

[0037] Each connecting track 3 is connected to the corresponding inductive building block 2 through through holes and snap-fit, which facilitates the assembly and disassembly of the entire blood glucose regulation demonstration device.

[0038] The spiral track 21 of each sensor block 2 is set to extend the rolling time of the ball 1 in the sensor block 2, that is, to keep the ball 1 rolling in the sensor block 2 for as long as possible. The rolling time can be set to 5 seconds.

[0039] The pressure-sensitive button 22 is connected to the LED strip 23 in the corresponding inductive block 2 via a circuit. When the ball 1 passes the pressure-sensitive button 22, the LED strip 23 is triggered to light up.

[0040] The rotary switch 24 is connected to the dual-color LED light strip via a circuit and is used to switch the dual-color LED light strip to display different colors to indicate that organs release different chemical substances or undergo different biochemical reactions under different physiological states.

[0041] The blood glucose regulation demonstration device provided in this embodiment also includes a collection base 5 for collecting the ball bearings 1 that pass through the connecting track 3 during the demonstration. In the digestive and absorption pathway, the collection base 5 is connected to the connecting track 302 representing the small intestine via the connecting track 303 representing blood vessels; in the blood glucose regulation pathway, the collection base 5 is connected to the sensor block 203 representing the pancreas, the sensor block 204 representing the liver, and the sensor block 205 representing fat via three connecting tracks 303 representing blood vessels.

[0042] When demonstrating the eating process, such as Figure 1As shown, labels (which can be stickers) corresponding to the organs are attached to the sensor-activated building blocks 2 and the connecting tracks 3, respectively. The sensor-activated building block 201 representing the oral cavity and the connecting track 301 representing the esophagus are connected via through holes and snap-fit ​​mechanisms. At this time, the connecting track 303 representing blood vessels, which represents blood vessels throughout the body, is connected to the sensor-activated building block 302 representing the small intestine. At this time, the end of the connecting track 303 representing blood vessels, away from the sensor-activated building block 302 representing the small intestine, is connected to a collection base 5.

[0043] A yellow ball representing glucose is placed at the upper opening of the sensor-activated block 201 representing the oral cavity. When the yellow ball passes the pressure-sensitive button 22 inside the block 201, a white LED light illuminates, indicating chewing. The yellow ball continues downwards through the connecting track 301 representing the esophagus to the sensor-activated block 202 representing the stomach. Passing the pressure-sensitive button 22 inside the stomach block 202, a white LED light illuminates, indicating digestion in the stomach. The yellow ball continues downwards to the connecting track 302 representing the small intestine and the connecting track 303 representing blood vessels, indicating glucose absorption into the bloodstream from the small intestine. The connecting track 303, representing blood vessels, has a rotating wheel 6 inside. The yellow ball drives the rotating wheel 6 to rotate, indicating that glucose absorbed from the small intestine enters the bloodstream and circulates throughout the body, providing energy. Finally, the yellow ball enters the collection base 5, indicating the end of the eating process.

[0044] During a demonstration of blood glucose regulation, such as... Figure 2 As shown, attach labels (which can be stickers) to the corresponding organs or tissues to the sensor-activated building blocks 2 and the connecting track 3 respectively.

[0045] During the demonstration of blood glucose regulation in the "full" state, the power switches for the sensory blocks 206 (representing the hypothalamus), 207 (representing skeletal muscle), 203 (representing the pancreas), 204 (representing the liver), and 205 (representing fat) are turned on, and the knob switch 24 is rotated to the "full" state. Five yellow beads representing glucose are placed at the upper opening of the sensory block 206 (representing the hypothalamus), indicating that the blood glucose level is high. When the yellow beads pass the pressure-sensitive button 22 inside the sensory block 206 (representing the hypothalamus), a red LED light illuminates, indicating that the increased blood glucose level sends a signal to the hypothalamus's blood glucose regulation center. At this time, a light blue bead representing neurotransmitters is placed at the upper opening of the sensory block 206 (representing the hypothalamus). This bead travels through the connecting track 304 (representing nerves) to the sensory block 203 (representing the pancreas), indicating that the hypothalamus is releasing neurotransmitter signals that act on the pancreas. A light blue ball passes the pressure-sensitive button 22 within the sensor block 203 representing the pancreas, illuminating a red LED strip. This indicates that pancreatic beta cells have received signals from the hypothalamus to regulate insulin release. At this time, multiple red balls representing insulin are continuously placed at the opening at the top of the sensor block 203 representing the pancreas. These red balls travel via three connecting tracks representing blood vessels to sensor blocks 207 representing skeletal muscle, 204 representing the liver, and 205 representing fat. After passing the pressure-sensitive buttons 22 on each sensor block, the red LED strip in the liver sensor block 204 illuminates, indicating that insulin regulates the gradual synthesis of liver glycogen; the red LED strip in the skeletal muscle sensor block 207 illuminates, indicating that insulin regulates the gradual synthesis of muscle glycogen; and the red LED strip in the fat sensor block 205 illuminates, indicating that insulin regulates the conversion of excess glucose into fat for storage. Finally, the red, yellow, and light blue beads are collected into the collection base 5 via the connecting track 303, which represents blood vessels.

[0046] During the demonstration of blood glucose regulation in a "hunger" state, the power switches for the sensory blocks 206 (representing the hypothalamus), 207 (representing skeletal muscle), 203 (representing the pancreas), 204 (representing the liver), and 205 (representing fat) are turned on, and the knob switch 24 is rotated to the "hunger" state. A yellow ball representing glucose is placed at the upper opening of the sensory block 206 (representing the hypothalamus), indicating that the blood glucose concentration is low. The yellow ball passes the pressure-sensitive button 22 inside the sensory block 206 (representing the hypothalamus), at which point the green LED light strip lights up, indicating that the blood glucose level has decreased and a signal has been sent to the blood glucose regulation center in the hypothalamus. At this time, a dark blue ball representing neurotransmitters is placed at the upper opening of the sensory block 206 (representing the hypothalamus). It travels through the connecting track 304 (representing nerves) to the sensory block 203 (representing the pancreas), indicating that the hypothalamus is releasing neurotransmitter signals that act on the pancreas. A dark blue ball passes over a pressure-sensitive button 22 within a sensor-activated block 203 representing the pancreas, and a green LED strip lights up, indicating that pancreatic A cells have received signals from the hypothalamus to regulate the release of glucagon. At this point, multiple green beads representing glucagon are continuously placed on the upper end of the sensor block 203 representing the pancreas. These green beads travel via the connecting track 303 representing blood vessels to the sensor blocks 207 representing skeletal muscle, 204 representing the liver, and 205 representing fat. After passing through the pressure-sensitive buttons 22 on each sensor block, the green LED strip in the liver sensor block 204 turns off, indicating that glucagon-regulated glycogen breakdown leads to an increase in blood glucose levels; the green LED strip in the skeletal muscle sensor block 207 turns off, indicating that glucagon-regulated muscle glycogen breakdown is used for energy; and the green LED strip in the fat sensor block 205 turns off, indicating that glucagon-regulated body fat is converted into glucose through gluconeogenesis. Finally, the yellow, green, and dark blue beads are all collected in the collection base 5 via the connecting track 303 representing blood vessels.

[0047] This invention provides a blood glucose regulation demonstration device. It uses inductive building blocks and connecting tracks to replace human organs and tissues, and connects them in sequence to build a model of a simulated human body. Through the coordinated action of the label 4, the knob switch 24 that changes the state of the human body, and the LED light strip 23, it can three-dimensionally display the position and cooperative relationship between the various organs involved in blood glucose regulation. It vividly and concretely demonstrates the blood glucose regulation process that cannot be directly observed in the human body, making it intuitive, clear, and easy for students to learn and understand.

[0048] This invention demonstrates the digestive process of food in the digestive system before blood sugar rises, integrating the entire process of eating and blood sugar elevation. It showcases both blood sugar regulation and the human digestive system's digestion of food, breaking down the limitations of individual modules and units in traditional teaching.

[0049] The demonstration device provided by this utility model allows students to personally participate in the process of building the sensory building blocks 2, pasting the corresponding labels 4, selecting human body status, and selecting and placing the ball bearings 1. This helps to stimulate students' learning interest, improve their hands-on skills, and enhance their memory of knowledge points.

[0050] Once the demonstration device is set up, the demonstration process only requires changing the knob switch 24 on the sensor block 2 to change the human body state, selecting and placing the ball 1, and then learning and observing by observing the lighting of the lights in each part. It is very convenient to operate and demonstrate, and its visualization and intuitiveness are also very helpful for students to imagine and learn.
