The infant leg venipuncture model is a commonly used training tool in nursing and medical teaching, aiming to help trainees master the basic skills of venipuncture for newborns and infants. During the usage process, the following matters should be noted:

First of all, before operation, it is necessary to check whether the appearance of the model and the vascular access are intact to ensure the smooth flow of the simulated blood, so as to guarantee the authenticity and continuity of the training.

Secondly, when performing puncture, trainees should master the correct selection of needles, angles and depths. Their movements should be gentle to avoid damaging the blood vessels or skin of the model.

Thirdly, during the training process, strictly follow the principle of aseptic operation. Keep your hands clean before and after use, and properly handle the needles and consumables. Fourth, after the operation is completed, the simulated blood should be drained in time, and the needle holes and the surface of the model should be cleaned to prevent residual liquid from causing the model to age or get clogged.

Finally, regular maintenance and inspection of the model should be carried out to maintain its elasticity and vascular elasticity, thereby extending its service life. By following these precautions, trainees can repeatedly practice in a safe and controllable environment, improving their operational skills and clinical confidence in infant venipuncture.
