The venipuncture model uses a variety of technical means to simulate the real human venous system, in order to be as close as possible to the real scene, and provide effective training and practice opportunities for medical personnel. Here is a detailed explanation of how the venipuncture model simulates the real human venous system:

1. Fine anatomical structure design

Venipuncture models typically have elaborate anatomical designs, including simulated skin layers, simulated blood vessels, and simulated subcutaneous tissue layers. These layers are made with specific processes and materials to simulate the look and feel of a real human vein system. The simulated skin layer uses soft and durable materials such as imported plastic or thermoplastic elastic blends to simulate the elasticity and toughness of real skin. Artificial blood vessels are made of transparent or translucent latex or silicone materials to clearly show the internal structure and blood flow of blood vessels.

2. Realistic blood flow simulation

To more realistically simulate the venipuncture process, some advanced venipuncture models are also equipped with blood circulation devices such as peristaltic pumps or electronic blood circulation devices. These devices are able to simulate real hemodynamics and produce blood circulation functions, allowing medical personnel to feel the pressure and speed changes of blood flow during practice. This real blood flow simulation helps to improve the coping ability and technical level of medical staff in the actual operation.

3. Rich training functions

Venipuncture model not only has fine anatomical structure and real blood flow simulation function, but also has rich training function. For example, the vein and blood vessel system on the model can simulate different parts of the vein and different thickness to meet different training needs. Medical staff can perform puncture training such as intravenous injection, infusion and blood drawing on the model, as well as intramuscular injection of the deltoid muscle. At the same time, the model can also simulate various situations in the process of puncture, such as the blood return phenomenon of correct puncture and the sense of resistance when puncture failure, so as to help medical staff better grasp the puncture skills and precautions.

4. Durability and replaceable

In order to ensure the long-term use effect of the model and reduce maintenance costs, venipuncture models usually have high durability. Parts such as simulated skin layers and simulated blood vessels on the model can be pierced multiple times without leakage or damage. In addition, some models are designed with replaceable component structures, such as replaceable skin and blood vessels, so that parts can be replaced when damaged or aged without the entire model being scrapped.

To sum up, the venipentesis model simulates the real human venous system through fine anatomical design, real blood flow simulation, rich training functions, durability and replaceable features. These characteristics make venipunction model one of the important tools for training and practice of medical staff.
