The operation norms of the venotomy model are mainly used in medical teaching and skills training, aiming to help learners master the basic methods of venotomy and puncture, improve operational proficiency, and reduce clinical risks. This model typically simulates the distribution of veins on the arm or the back of the hand, with distinct vascular directions marked on the surface. It also uses flexible materials to reproduce the feel of the skin and tissues, allowing learners to conduct realistic training.

The operation norms generally include the following steps: First, learners should be familiar with the vascular position of the model and select the appropriate incision point and puncture Angle. Secondly, strictly follow the principle of aseptic operation, disinfect hands, wear gloves and prepare the necessary instruments. Subsequently, use an injection needle or intravenous catheter to perform incision or puncture practice on the model blood vessels, paying attention to mastering the depth and direction of needle insertion to simulate blood reflux or the patency of the lumen.

During the training process, the techniques of hemostasis, immobilization and bandaging should be repeatedly practiced to ensure the integrity and safety of the operation. Some high-end models also have the functions of recirculating water injection or simulating blood flow, which can enhance the realism of operation and enable learners to understand venous anatomy and puncture techniques more intuitively.

Through standardized operation training of the venotomy model, learners can master the technical essentials in a risk-free environment, enhance their sense of touch and operational confidence, lay a solid foundation for clinical venipuncture and infusion operations, and effectively reduce the risk of medical accidents in actual operations.
