The operation specification of the unilateral infant head venipuncture training model is mainly used to standardize the training steps of nursing staff in infant scalp venipuncture and help trainees master the correct operation method proficiently.

Before training, the integrity of the model should be checked first. Prepare items such as puncture needles, infusion sets, and simulated blood, and keep the operating environment clean.

During the operation, the trainees need to first soothe and position the "child patient" to expose the puncture site. Subsequently, the scalp puncture area was routinely disinfected. The left hand fixed the model head and gently pressed the vein direction, while the right hand held the needle and inserted it along the direction of the blood vessel's course, paying attention to the Angle and depth of the needle insertion. After successfully entering the vascular lumen, blood return can be observed. Then, fixation, connection of the infusion device and adjustment of the drip rate are carried out.

The entire process must strictly follow the principle of aseptic operation to avoid repeated punctures causing discomfort to the "child patient". After the operation is completed, the needle should be properly removed, pressure applied to stop the bleeding, and the model should be cleaned and organized to maintain its reusable performance. Through repeated practice with this model, trainees can not only master the operation skills of venous puncture of the infant's head, but also cultivate good clinical thinking and humanistic care awareness, providing a strong guarantee for future clinical practice.
