[0002] Injection is the process of injecting medicine into the human body with the help of medical devices such as syringes to achieve the purpose of diagnosis, treatment and prevention of diseases. Before taking up their posts, nurses in hospitals will learn about injection operations. When teaching nurses about injection, the teaching doctor will demonstrate the injection operation on a rubber profiling injection model. The teaching doctor will demonstrate and explain the steps of injection, and then the nurse will imitate the demonstration on the profiling injection model. Each injection teaching is carried out using the same profiling injection model. The profiling injection model is fixedly mounted on the bracket, and the state of the profiling injection model is fixed. The main demonstration operation area of the profiling injection model is the exposed upper surface. After multiple rounds of teaching demonstrations, a large number of demonstration holes will appear on the upper surface of the profiling injection model due to frequent punctures, which will affect the teaching demonstration. The entire injection model needs to be replaced for subsequent teaching work. At the same time, the demonstration area of the profiling injection model is made of the same rubber. When teaching nurses about injections in different hardness areas, it is also necessary to replace the entire injection model or reselect another injection model. The operation is not convenient enough. Replacing the injection model will increase the teaching time and difficulty, which will affect the fluency and teaching effect of injection teaching for nurses. Summary of the invention
