The electronic arm venipuncture model is an indispensable and important tool in the field of modern medical education. It provides a safe and controllable training environment for medical staff by simulating the real human arm venous system. The training methods and puncture techniques of this model will be introduced in detail below.

1. Training methods

Familiar with the model structure: Before starting training, medical staff need to fully understand the structure and function of the electronic arm venipuncture model. This includes understanding the model's blood vessel distribution, blood flow simulation mechanisms, and how electronic sensors work. By becoming familiar with the model structure, medical staff can better understand the mechanical changes and physiological responses during the puncture process.

Simulated puncture practice: Medical staff can use the model to perform repeated puncture practice. During the practice, attention should be paid to adjusting the puncture angle, strength and depth to simulate various situations in actual clinical operations. At the same time, the model can also be set up with different vascular conditions and pathological states, so that medical staff can train in various complex scenarios.

Real-time feedback and evaluation: The electronic arm venipuncture model has real-time feedback function, which can display the accuracy and depth of puncture. Medical staff should pay close attention to feedback information during practice and adjust operating techniques in a timely manner. In addition, the model can also record and analyze the operational data of medical staff, providing strong support for teaching evaluation and personalized training.

2. Puncture skills

Stabilize hands: Healthcare professionals should maintain hand stability while performing punctures. The left hand holds the patient's hand, skin and blood vessels while the right hand holds the needle. Choose a suitable fulcrum and avoid hanging operations to ensure a stable fingertip feel and control the depth of the needle as well as the angle and direction of the needle insertion.

Tourniquet position: The tourniquet should be placed 10 to 15cm proximal to the heart of the puncture site, with moderate tightness and should not be too long. This can effectively reduce the patient's pain and improve the success rate of puncture.

Adjust the back of the patient's hand: During venipuncture on the back of the hand, the natural state of the back of the patient's hand should be adjusted to avoid excessive clenching of the fist, which may cause high tension on the skin on the back of the hand. Smoothing the skin on the back of the hand helps to better observe the direction of blood vessels and improve the accuracy of puncture.

Needle holding method and needle insertion angle: When holding the needle with the right hand, the index finger and thumb should control the front and rear ends of the needle handle, and the other three fingers serve as fulcrums to stabilize the needle. The angle of needle insertion should be adjusted according to the specific situation. It is usually recommended to insert the needle at an angle of about 60 degrees to the skin. This can reduce the scope of skin damage, increase the needle insertion pressure, speed up the needle insertion, and reduce the patient's pain.

By combining the training methods and puncture skills of the electronic arm venipuncture model, medical staff can continuously improve their venipuncture skills in a safe and controlled environment, laying a solid foundation for clinical operations. At the same time, this training method can also help reduce clinical operation risks and improve patient satisfaction and medical quality.
