The full-function venipuncture and infusion arm model is a simulation device widely used in teaching and skills training in nursing, medicine and related fields. It is mainly used for training basic clinical skills such as venipuncture, infusion and blood collection.

This model is designed based on the anatomical structure and proportion of an adult arm. The skin texture is realistic, and the vein course is clearly palpable. After successful puncture, it can generate a blood return prompt, enhancing the authenticity of the operation. Users can practice performing venipuncture and indwelling needle insertion at different sites on the model, mastering the Angle, force and fixation techniques of inserting the needle. At the same time, they can also perform operations such as injecting liquid medicine, intravenous infusion and blood return observation.

Some advanced models support multiple repeated punctures, and the vascular system can be replaced, which is convenient for long-term teaching use. Through the training of this model, learners can repeatedly practice in a risk-free environment, become familiar with the standard procedures of venipuncture, improve the accuracy and proficiency of the techniques, and avoid causing injuries to patients due to lack of experience. The promotion and application of the full-function venipuncture and infusion arm model not only helps to improve the quality of nursing teaching, but also provides a strong guarantee for cultivating qualified clinical skilled talents.
