Description

Technical Field

[0001] This utility model relates to the field of medical teaching equipment technology, and more specifically, to a clinical simulation subcutaneous edema teaching equipment. Background Technology

[0002] Subcutaneous edema is a common clinical sign, frequently seen in various diseases such as heart failure, renal insufficiency, and malnutrition. In medical education, enabling students to accurately identify the clinical manifestations of subcutaneous edema and master palpation methods and assessment techniques is both a key focus and a challenge.

[0003] Based on the above, the inventors have discovered that current teaching methods mainly rely on real cases or illustrations, which suffer from limited case resources, restricted teaching scenarios, and few opportunities for student practice. Although some simulated human models are used in clinical teaching, their structures are complex, costly, and difficult to accurately simulate the local characteristics of subcutaneous edema, such as indentation and elasticity changes. Therefore, in view of this, the inventors have researched and improved the existing structures to provide a clinical simulation subcutaneous edema teaching device, aiming to achieve a more practical value.

It can simulate the symptoms of subcutaneous edema, solve the problems of limited case resources, limited teaching scenarios, and few student practice opportunities caused by relying on real cases or illustrations in teaching, and overcome the shortcomings of existing simulated human body models such as complex structure, high cost, and poor simulation accuracy.

[0006] 2. Technical Solution

A base is located below the limb model, and a cap is installed on one side of the limb model. An anti-slip base is installed below the base.

[0009] Furthermore, a mounting head is fixedly provided at the bottom of the base, and an arc-shaped groove is provided at the top of the base, with an internal thread on the inner sidewall of the mounting head.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] Example:

[0026] Please see Figure 1-4 A clinical simulation teaching device for subcutaneous edema includes a limb model 1. A bionic skin layer 8 is fitted on the outer side of the limb model 1. An elastic filling layer 9 is fixed on the inner side of the bionic skin layer 8. A liquid sac 10 is installed inside the elastic filling layer 9. An infusion tube 4 is installed on one side of the liquid sac 10. The liquid sac 10 is connected to a pressure regulator 5 through the infusion tube 4. A pressure regulator 5 is provided on one side of the infusion tube 4. A connector 6 is threadedly connected to one side of the pressure regulator 5. A base 3 is provided below the limb model 1, and a cap 2 is installed on one side of the limb model 1. An anti-slip base 7 is installed below the base 3.

[0027] See Figure 1 and Figure 3 The base 3 has a fixed mounting head 31 at its bottom and an arc groove 32 on its upper part. The inner wall of the mounting head 31 has an internal thread. The arc groove 32 allows the limb model 1 to be tilted at a certain angle, which is convenient for teaching demonstration.

[0028] See Figure 1 and Figure 3 A threaded connector is fixedly provided on the top of the anti-slip base 7. The threaded connector is connected to the internal thread, and the threaded connector and the internal thread are used for quick disassembly and assembly of the anti-slip base 7.

[0029] See Figure 1 and Figure 2 The pressure regulator 5 is located on the side of the limb model 1. The pressure is adjusted by the control system to simulate the different manifestations of mild, moderate and severe subcutaneous edema. The pressure regulator 5 is connected to the infusion tube 4 through the connector 6 to realize the injection and discharge of fluid.

[0030] See Figure 1 and Figure 2 The pressure regulator 5 includes a micro pump, a regulating valve, and a pressure sensor, which are used to monitor and control the pressure changes inside the liquid bag 10 in real time. By adjusting the liquid pressure inside the liquid bag 10 through the control system, the system can simulate the symptoms of subcutaneous edema of different degrees.

[0031] See Figure 3 and Figure 4 Both the bionic skin layer 8 and the liquid sac 10 are made of medical silicone material. The liquid sac 10 is filled with a transparent liquid that simulates tissue fluid. The liquid sac 10 is connected to the pressure regulator 5 through the infusion tube 4.

[0032] See Figure 3 and Figure 4 The inner side of the bionic skin layer 8 is provided with two sets of symmetrical slots 12, and a locking strip 11 is fixed on one side of the cover 2. The locking strip 11 is engaged with the slots 12, and the locking strip 11 and the slots 12 are used for quick disassembly and assembly of the cover 2.

[0033] In use: First, the limb model 1 is mounted on the anti-slip base 7 via the base 3. The base 3 has an mounting head 31 at its bottom, with internal threads on its inner wall, which mate with the threaded connector on the anti-slip base 7 for a secure connection. The arc-shaped groove 32 allows the limb model 1 to be tilted at a certain angle, facilitating teaching demonstrations. The pressure regulator 5 is turned on, and the required pressure value is set through the control system. The micro-pump delivers liquid to the liquid bag 10, causing it to expand and simulate subcutaneous edema. Students press the surface of the bionic skin layer 8 to observe the formation and recovery of indentations, simulating the characteristics of clinical "pitting edema." Teachers can switch the caps 2 at different locations and change the liquid bags 10 with different pressure settings according to teaching needs, training students to identify edema symptoms of different locations and severity. After use, the caps 2 can be removed through the locking structure of the slot 12 and the locking strip 11 to clean and replace the bionic skin layer 8 and the liquid bag 10, facilitating long-term use.
