Preparation Phase:

First, make sure the model has been installed correctly and is in working order.

Check whether the skin, blood vessels and other parts of the model are intact to ensure the authenticity of the simulation.

According to training needs, the parameters of the model, such as blood pressure, blood flow velocity, etc., are adjusted to simulate the physiological states of different patients.

Locate the artery:

Use manual pressure to simulate the rubber ball to simulate arterial pulsation and feel the radial artery pulsation of the arm model.

Carefully observe and touch the blood vessels in the model arm to determine the best site for arterial puncture. This step is very important because it is directly related to the success of the puncture.

Disinfection and fixation:

Perform routine disinfection at selected puncture sites to ensure sterility of the procedure.

Use your left hand to hold the pulse site in place to ensure that the vessel remains stable during puncture.

Puncture operation:

Hold the syringe in your right hand and ensure that the needle is inserted at a certain angle to the skin (usually 30 to 45 degrees). The concentration should be moderate to avoid puncturing the blood vessel wall.

During the puncture process, pay close attention to the real-time feedback of the model to ensure the accuracy and depth of the puncture.

Collect blood:

Once the puncture is successful, blood will automatically enter the syringe. At this time, make sure that the amount of blood in the syringe is appropriate and avoid too much or too little.

Needle removal and subsequent treatment:

When withdrawing the needle, pull it out quickly and smoothly to avoid additional damage to the blood vessels.

After removing the needle, apply appropriate compression and bandage to the puncture site to prevent bleeding and infection.

Records and feedback:

During the entire operation process, each step of the operation and the feedback from the model must be recorded in detail.

Based on the recorded results, analyze the strengths and weaknesses in your operations in order to make targeted improvements.

Through repeated practice and continuous summarization of experience, medical staff can gradually master the skills and key points of arterial puncture and improve the accuracy and safety of the operation. At the same time, the high degree of simulation and adjustability of the advanced arterial puncture arm model also provides medical staff with a more realistic and comprehensive training environment, helping them better deal with various complex situations in clinical practice.
