The purpose of the arterial puncture arm model

The main purpose of the arterial puncture arm model is to provide medical staff with a safe and repeatable platform for arterial blood collection and puncture training, helping trainees master standardized operations under risk-free conditions.

The model has a high degree of simulation, featuring palpable radial artery pulsation, realistic skin elasticity and vascular course, allowing trainees to practice key steps such as touch positioning, needle insertion Angle control, blood exposure during suction, and fixation of the puncture needle. Meanwhile, the model can simulate common situations such as failed puncture and insufficient blood return, making the practice more in line with clinical scenarios.

Its application purposes include improving the skills of arterial blood gas sampling, enhancing the ability of tactile judgment, avoiding the risks brought by repeated practice on real patients, and providing reliable support for teaching demonstrations, skills assessment and preclinical training. Overall, this model is conducive to enhancing the proficiency and safety of medical staff in arterial puncture operations.
