The correct use of venipuncture infusion arm model for training is a key step to improve the venipuncture skills of nursing staff. Here are detailed steps and considerations on how to properly train using this model:

1. Prepare

Select the model: Ensure that the selected venipuncture infusion arm model is anatomically similar to the actual human arm and has a clear venous system.

Environment preparation: Ensure that the training environment is clean, tidy and meets the requirements of aseptic operation.

Prepare tools: Prepare the necessary syringes, needles, disinfectant, sterile gloves, etc.

2. Arm model installation and preparation

Install the model: Follow the instructions in the manual to properly install the arm model and ensure that all components are firmly fixed.

Filling blood vessels: Use red simulated blood to fill blood vessels as needed to simulate the filling state of real blood vessels.

3. Disinfection and skin preparation

Sterilizing the arm model: The surface of the model is sterilized with disinfectant to simulate the skin disinfection process of real patients.

Tighten the skin: Hold the fingers of the pierced hand so that the pierced hand is fixed into a cup-like hand with an empty back and palm, and tighten the skin for piercing.

4. Puncture operation

Select veins: Observe the veins on the model and select the appropriate vein for puncture, usually choosing a relatively thick and obvious vein.

Injection Angle: Direct injection method is adopted, the injection Angle is about 60 degrees from the skin, and the needle is quickly injected. Pay attention to avoid too small Angle resulting in needle insertion difficulties or too large Angle damage to blood vessels.

Puncture technique: ensure "steady, accurate and fast", evaluate the thickness of subcutaneous fat, decide the depth of injection, and directly stab the blood vessel before sending the needle. Take care to avoid repeated piercings or adjusting the needle position multiple times to reduce pain and discomfort for the patient.

5. Transfusion or blood drawing operation

Infusion operation: Connect the infusion set, adjust the infusion speed, and observe whether the infusion is smooth and whether there is leakage or blood return.

Blood drawing operation: Use a syringe to draw blood and observe whether the simulated blood is successfully drawn.

6. Pull the needle and clean

Needle extraction: After infusion or blood drawing, gently pull out the needle and press the eye of the needle with a cotton swab for a moment.

Clean and disinfect: The entire arm model is cleaned and disinfected in preparation for the next use.

7. Precautions

Aseptic operation: During the entire training process, the principles of aseptic operation should be strictly observed to avoid infection.

Safe use: Avoid damaging the model with sharp objects or violent handling.

Repeated practice: Improve piercing skills through repeated practice to ensure that the piercing task can be accurately and quickly completed in the actual operation.
