The function of the simulated arm for children's venous puncture

The pediatric venipuncture simulation arm is a simulation tool specially designed for nursing teaching and clinical training. Its main function is to help trainees familiarize themselves with the anatomical characteristics and operational essentials of pediatric venipuncture. Due to the small and elastic nature of children's blood vessels, clinical puncture is highly challenging and prone to failure or increased pain for the children during practical operations. Therefore, this simulated arm provides a safe and risk-free practice platform for trainees.

This model typically features soft simulated skin and a replaceable vascular system design, enabling puncture operations on the back of the hand, forearm, and other areas. It provides real feedback through a blood return device to help trainees determine whether the puncture was successful. During the usage process, trainees can repeatedly practice the touch positioning of blood vessels, as well as the mastery of the needle insertion Angle and depth, thereby gradually improving their sense of touch and skill proficiency.

Through the training of the simulated arm for children's venipuncture, medical staff can accumulate experience without harming real children, reduce clinical errors, and improve the success rate of operations and the quality of care. At the same time, it also provides scientific means for teaching and assessment, promoting trainees to transform theoretical knowledge into practical abilities.
