Description

Technical Field

[0001] This utility model relates to the field of teaching tools, and more specifically, to a teaching tool for cholestatic jaundice. Background Technology

[0002] Cholestatic jaundice is a type of jaundice caused by impaired bile secretion due to mechanical or non-mechanical factors, resulting in the reflux of bilirubin from bile into the bloodstream. Typical clinical manifestations include yellowing of the skin and sclera, darkened urine, and lighter-colored stools, often accompanied by itching, fatigue, loss of appetite, and discomfort in the right upper quadrant. In severe cases, patients may experience steatorrhea due to the inability of bile to participate in fat digestion, or bleeding tendencies due to fat-soluble vitamin deficiencies. The causes of cholestatic jaundice can be divided into intrahepatic and extrahepatic factors, such as gallstones, tumors, parasites, viral hepatitis, and medications. Diagnosis of cholestatic jaundice requires a comprehensive assessment of the liver and bile duct function, taking into account the patient's clinical symptoms, laboratory tests, and imaging results, to determine the specific cause and formulate an appropriate treatment plan.

[0003] Currently, in teaching cholestatic jaundice, traditional two-dimensional teaching methods (such as static photographs and diagrams) lack dynamic visualization, resulting in insufficient intuitiveness. This approach not only fails to present the pathophysiological process of bile excretion obstruction in a three-dimensional way, but also keeps students' understanding of core mechanisms such as bilirubin metabolism and bile salt deposition at a two-dimensional level, increasing the difficulty of knowledge memorization. Furthermore, because two-dimensional teaching cannot intuitively connect the normal bilirubin metabolism process in physiology with the principle of biliary obstruction in pathophysiology, students struggle to systematically reconstruct multidisciplinary knowledge, resulting in a significant gap in the process of transforming basic theory into clinical case thinking. Based on these teaching pain points, this invention proposes an innovative solution that overcomes the limitations of two-dimensional teaching to improve the intuitiveness of teaching and the efficiency of knowledge integration. Utility Model Content

[0004] This invention aims to address the shortcomings of current teaching methods for diagnosing cholestatic jaundice, which rely on static photographs and two-dimensional illustrations to explain clinical symptoms. Traditional teaching methods lack dynamic and three-dimensional presentation of pathological features, making it difficult for students to understand the mechanisms underlying typical symptoms such as yellowing of the skin and sclera, and clay-colored stools. This increases the difficulty of connecting knowledge with clinical scenarios. Based on the above background, a teaching tool for cholestatic jaundice is proposed.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A teaching tool for cholestatic jaundice includes a housing. Inside the housing are installed a head and face simulation component, a trunk simulation component, a liver simulation component, a colon simulation component, and a urinary system simulation component.

[0009] As a preferred embodiment of this invention, the liver simulation component, the colon simulation component, the kidney model, and the bladder model are all hollow structures and are semi-transparent.

[0010] As a preferred technical solution of this utility model, the liquid supply assembly includes a storage tank and a recycling tank installed inside the housing. A delivery pump is installed on the top of the recycling tank. The input end of the delivery pump is inserted into the interior of the recycling tank, and the output end of the delivery pump is inserted into the interior of the storage tank.

[0011] As a preferred technical solution of this utility model, a liquid filling pipe is installed on the top of the storage box, penetrating the top of the outer shell. The top end of the liquid filling pipe is threadedly connected to a pipe cap located on the outside of the outer shell. A drain pipe is installed on the side wall of the recycling box, penetrating the outer shell. The end of the drain pipe away from the recycling box is threadedly connected to a plug located on the outside of the outer shell.

[0012] As a preferred technical solution of this utility model, the outer shell includes a housing, a transparent writing board is installed on the front of the housing, a partition for separating the torso simulation component and the liquid supply component is fixedly installed inside the housing, and a back plate is installed on the back of the housing.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Example

[0018] like Figures 1-5As shown, this embodiment proposes a teaching tool for cholestatic jaundice, including a shell 1. Inside the shell 1 are installed a head and face simulation component 3, a trunk simulation component 4, a liver simulation component 5, a colon simulation component 6, and a urinary system simulation component 7. The head and face simulation component 3 is installed on top of the trunk simulation component 4, the liver simulation component 5 is installed on the front of the trunk simulation component 4, the colon simulation component 6 is located below the liver simulation component 5, and the urinary system simulation component 7 is located to one side of the liver simulation component 5. Through the arrangement of the liver simulation component 5, the colon simulation component 6, and the urinary system simulation component 7, and through the interconnection of the liver simulation component 5, the colon simulation component 6, and the urinary system simulation component 7, the circulation and excretion process of bilirubin is simulated. This system assists teachers in better explaining the relationship between the pathophysiological processes and clinical manifestations of patients with cholestatic jaundice, making the teaching content more intuitive and vivid. This helps students better understand and remember complex medical knowledge, enhancing learning outcomes. A fluid flow pipeline is installed between the trunk simulation component 4, liver simulation component 5, colon simulation component 6, and urinary system simulation component 7. Valves 13 are installed on the pipeline, and a fluid supply component that works in conjunction with the pipeline is installed inside the outer casing 1. Through the fluid supply component, pipeline, and valve 13 setup, the teacher can operate the valve 13 to control the flow of simulated fluid during the teaching process, while students can also manually operate the valve 13 to control the flow of fluid inside the pipeline, effectively improving interactivity during the teaching process.

[0019] like Figure 1 and Figure 2As shown, in a preferred embodiment, based on the above method, the urinary system simulation component 7 includes a kidney model 701 and a bladder model 702. The bladder model 702 is located inside the colon simulation component 6, and the kidney model 701 is located above the colon simulation component 6. The pipeline includes a first input pipe 8 connecting the liquid supply component and the liver simulation component 5, a first connecting pipe 9 connecting the liver simulation component 5 and the colon simulation component 6, a second connecting pipe 10 connecting the colon simulation component 6 and the kidney model 701, a third connecting pipe 11 connecting the kidney model 701 and the bladder model 702, a fifth connecting pipe 22 connecting the first input pipe 8 and the kidney model 701, and a second input pipe 23 connected to the first input pipe 8. The bottom end of the colon simulation component 6 is equipped with an outlet pipe 14, and the bottom end of the bladder model 702 is equipped with a fourth connecting pipe 12 that communicates with the interior of the outlet pipe 14. It should be noted that during use, the liquid supply component delivers the yellow liquid used to simulate bile to the liver simulation component 5 through the first input tube 8. The yellow liquid entering the liver simulation component 5 enters the colon simulation component 6 through the first connecting tube 9. Part of the liquid in the colon simulation component 6 enters the kidney model 701 through the second connecting tube 10, and the remaining liquid is discharged through the discharge tube 14. The liquid in the kidney model 701 enters the bladder model 702 through the third connecting tube 11, and then is discharged into the discharge tube 14 through the fourth connecting tube 12, thereby simulating the circulation and excretion process of bilirubin.

[0020] like Figure 1 and Figure 2 As shown, in a preferred embodiment, based on the above method, the liver simulation component 5, colon simulation component 6, kidney model 701, and bladder model 702 are all hollow structures and semi-transparent. It should be noted that the hollow structure facilitates the entry and exit of liquids, while the semi-transparency facilitates observation by students.

[0021] The working principle of this teaching tool for cholestatic jaundice is as follows: During use, the liquid supply component delivers yellow liquid, used to simulate bile, to the liver simulation component 5 through the first input tube 8. The yellow liquid entering the liver simulation component 5 enters the colon simulation component 6 through the first connecting tube 9. Part of the liquid in the colon simulation component 6 enters the kidney model 701 through the second connecting tube 10, and the remaining liquid is discharged through the discharge tube 14. The liquid in the kidney model 701 enters the bladder model 702 through the third connecting tube 11, and then is discharged into the discharge tube 14 through the fourth connecting tube 12, thereby simulating the circulation and excretion process of bilirubin. Through the liquid supply component, pipelines, and valve 13, the teacher can operate the valve 13 to control the flow of the simulated liquid during the teaching process, and students can also manually operate the valve 13 to control the flow of liquid inside the pipeline, which can effectively improve the interactivity of the teaching process. Example

[0022] like Figure 1 , Figure 3 and Figure 4 As shown, in a preferred embodiment, based on the above method, the liquid supply assembly further includes a storage tank 15 and a recovery tank 16 installed inside the housing 1. A delivery pump 19 is installed on the top of the recovery tank 16, with its input end inserted into the recovery tank 16 and its output end inserted into the storage tank 15. It should be noted that during use, the liquid inside the storage tank 15 enters the liver simulation assembly 5 through the first input pipe 8. The delivery pump 19 allows the liquid discharged from the discharge pipe 14 into the recovery tank 16 to be re-delivered to the storage tank 15 for recycling.

[0023] like Figure 1 , Figure 3 and Figure 4 As shown, in a preferred embodiment, based on the above method, a liquid filling pipe 17 penetrating the top of the outer shell 1 is further installed on the top of the storage tank 15. The top end of the liquid filling pipe 17 is threadedly connected to a pipe cap 18 located on the outside of the outer shell 1. A drain pipe 21 penetrating the outer shell 1 is installed on the side wall of the recovery tank 16. The end of the drain pipe 21 away from the recovery tank 16 is threadedly connected to a plug 20 located on the outside of the outer shell 1. It should be noted that the liquid filling pipe 17 allows for convenient injection of liquid into the storage tank 15, and the drain pipe 21 allows for the drainage of liquid from the recovery tank 16 when not in use.

[0024] like Figure 1 and Figure 3As shown, in a preferred embodiment, based on the above method, the outer shell 1 further includes a shell 101, a transparent writing board 102 mounted on the front of the shell 101, a partition 104 for separating the torso simulation component 4 and the liquid supply component fixedly mounted inside the shell 101, and a back plate 103 mounted on the back of the shell 101. It should be noted that the transparent writing board 102 facilitates writing or marking with a whiteboard marker during explanations, and the partition 104 separates the torso simulation component 4 and the liquid supply component.

[0025] like Figure 1 and Figure 5 As shown, in a preferred embodiment, based on the above method, a bracket 2 is further installed at the bottom of the outer casing 1. The bracket 2 includes a base plate 201, with self-locking casters 203 installed at each of the four corners of the bottom of the base plate 201. Two sleeves 202 are symmetrically installed on the top of the base plate 201. A sliding rod 204 is slidably installed inside the sleeve 202, with the top end of the sliding rod 204 connected to the bottom of the outer casing 1. A screw 205 is threadedly connected to the side wall of the sleeve 202. It should be noted that the base plate 201 and the self-locking casters 203 facilitate the movement of the outer casing 1. The sleeves 202, sliding rods 204, and screws 205 allow for adjustment of the length of the sliding rod 204 extending from the sleeve 202 during use. Then, the screw 205 is tightened to lock the sliding rod 204, thereby adjusting the height of the outer casing 1, making it more flexible and convenient to use.

[0026] The working principle of this teaching tool for cholestatic jaundice is as follows: When in use, the liquid inside the storage tank 15 enters the liver simulation component 5 through the first input tube 8. With the setting of the delivery pump 19, the liquid discharged into the recycling tank 16 through the discharge tube 14 can be transported back to the storage tank 15 for recycling. During use, the overall height of the outer shell 1 can also be adjusted by the bracket 2. When explaining, the teacher can use a whiteboard marker to write or mark on the transparent writing board 102.

[0027] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above.
