Description

Technical Field

[0001] This utility model relates to the technical field of nephron simulation devices, specifically to a nephron simulation device. Background Technology

[0002] In recent years, in classroom teaching, especially in the section on "The Excretion of Waste Products in the Human Body" in the second semester of the first year of junior high school biology, the explanation of the key and difficult knowledge of the structure and function of the nephron is often done using multimedia courseware or non-operable models. However, the teaching effect is often not ideal, and students say that they do not have a deep enough grasp of the knowledge.

[0003] Traditional nephron models are kidney structure models made according to anatomical principles. They are simple and rigid, and only collectively display the kidney structure, failing to let students understand the flow and filtration function of the nephron. Utility Model Content

[0004] The purpose of this invention is to provide a nephron simulation device to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] This utility model discloses a nephron simulation device, comprising a support plate. The lower part of the front of the support plate is provided with a renal vein simulation bottle and a bladder simulation bottle, the middle part of the front is provided with a water pump and a glomerular simulation bottle, and the upper part of the front is provided with a renal artery simulation bottle. The renal vein simulation bottle, water pump, renal artery simulation bottle, glomerular simulation bottle, and bladder simulation bottle are connected in sequence by a hose. The renal vein simulation bottle is also connected to the glomerular simulation bottle by a hose. A battery is provided on the back of the support plate, and the battery is electrically connected to the water pump.

[0007] As an improvement, the tubing connecting the bladder simulator is equipped with a flow rate regulator.

[0008] As an improvement, the renal vein simulation bottle contains iodine solution, and the glomerular simulation bottle contains vitamin C powder.

[0009] As an improvement, the renal vein simulation bottle, bladder simulation bottle, water pump, glomerular simulation bottle, and renal artery simulation bottle are fixedly connected to the support plate.

[0010] The advantages of this invention compared to the prior art are as follows: the flexible tube can be folded to simulate real blood vessels; the iodine solution in the renal vein simulation bottle is drawn into the renal artery simulation bottle by a water pump; the iodine solution falls from the renal artery simulation bottle into the glomerular simulation bottle; the glomerular simulation bottle contains vitamin C powder; the vitamin C powder reduces the iodine solution, making the dark brown color of the iodine solution lighter; and then it falls into the bladder simulation bottle; the flow rate regulator is used to adjust the flow rate.

[0011] The flow rate controller simulates and regulates blood pressure and the urethra to expel urine. Vitamin C powder reacts with iodine solution to simulate the effect of glomerular filtration. A folded tubing increases the pressure of blood flow. A water pump simulates the circulatory system, allowing fluid from the renal vein to flow through the renal artery to form a closed loop, thereby simulating the filtration effect of blood flowing through the kidneys.

[0012] This nephron simulator, when used in formal classrooms, is easy to operate, has good visual effects, attracts students' attention, and is highly engaging. It helps students grasp the concept that "blood is filtered through the glomeruli and Bowman's capsule and reabsorbed by the renal tubules to form urine," and helps to further systematically improve their understanding and construction of the broader concept that "the structure and function of the human body are adapted to each other, and the various systems coordinate and work together to complete complex life activities."

[0017] 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.

[0018] In the description of the embodiments of this utility model, it should be noted that if terms such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" appear, the indicated orientation or positional relationship is based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship that the utility model product is usually placed in during use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0019] Furthermore, the terms "first," "second," and "third" are used only for distinguishing descriptions and should not be interpreted as indicating or implying relative importance. The use of terms such as "horizontal," "vertical," and "suspended" does not imply that the component must be absolutely horizontal or suspended, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," not that the structure must be perfectly horizontal, but can be slightly tilted.

[0020] In the description of the embodiments of this utility model, the terms "multiple" or "several" refer to at least two.

[0021] In the description of the embodiments of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0022] This embodiment is combined with the appendix Figure 1 This paper provides a detailed description of a nephron simulation device.

[0023] This embodiment discloses a nephron simulation device, including a support plate 1. The lower part of the front of the support plate 1 is provided with a renal vein simulation bottle 2 and a bladder simulation bottle 3, the middle part of the front is provided with a water pump 4 and a glomerular simulation bottle 5, and the upper part of the front is provided with a renal artery simulation bottle 6. The renal vein simulation bottle 2, the water pump 4, the renal artery simulation bottle 6, the glomerular simulation bottle 5, and the bladder simulation bottle 3 are connected in sequence by a flexible tube 7. The renal vein simulation bottle 2 is also connected to the glomerular simulation bottle 5 by a flexible tube 7. A battery is provided on the back of the support plate 1, and the battery is electrically connected to the water pump 4.

[0024] The tubing 7 connected to the bladder simulation bottle 3 is equipped with a flow rate regulator 8.

[0025] The renal vein simulation bottle 2 contains iodine solution, and the glomerular simulation bottle 5 contains vitamin C powder.

[0026] The renal vein simulation bottle 2, bladder simulation bottle 3, water pump 4, glomerular simulation bottle 5, and renal artery simulation bottle 6 are fixedly connected to the support plate 1.

[0027] In practice, the flexible tube 7 can be folded to simulate real blood vessels. The iodine solution in the renal vein simulation bottle 2 is drawn into the renal artery simulation bottle 6 by the suction pump 4. The iodine solution falls from the renal artery simulation bottle 6 into the glomerular simulation bottle 5. The glomerular simulation bottle 5 contains vitamin C powder. The vitamin C powder reduces the iodine solution, making the dark brown color of the iodine solution lighten, and then it falls into the bladder simulation bottle 3. The flow rate regulator 8 is used to adjust the flow rate.

[0028] The flow rate controller 8 simulates and regulates blood pressure and simulates the urethra to expel urine. Vitamin C powder reacts with iodine solution to simulate the effect of glomerular filtration. The folded hose 7 increases the pressure of blood flow. The suction pump 4 simulates the circulatory system, allowing the fluid from the renal vein to flow through the circulatory system to the renal artery to form a closed loop, thereby simulating the filtration effect of blood flowing through the kidney.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this invention should be included within the scope of protection of this invention. Therefore, the scope of protection of this invention should be determined by the scope of the claims.
