Arterial puncture arm model Q&A Tablets

The arterial puncture arm model is a teaching tool specifically designed for pre-skill training in arterial blood collection and blood gas analysis. It is based on the anatomical structure of the human forearm, with clear arterial routes and realistic touch sensations. It can simulate the pulsation of the radial artery, providing trainees with a clinical experience close to reality. Through this model, learners can repeatedly practice key links such as arterial positioning, selection of puncture angles, and control of needle tip insertion depth, thereby reducing risks caused by lack of experience in clinical practice.

During the operation, trainees need to first touch the radial artery pulsation point according to the anatomical landmarks, select the appropriate puncture position and Angle, and then carry out standardized disinfection, fixation and needle insertion. The model is equipped with a simulated blood circulation system inside. When the puncture is successful, blood will flow back, helping trainees to visually judge the operation effect. This feedback mechanism has greatly enhanced the pertinence and practical value of learning.

The advantage of this model lies in its reusability. It can be used not only for individual repeated training but also for collective teaching and assessment, truly achieving a closed-loop teaching of "learning - practicing - testing - evaluating". Through the study and operation of the arterial puncture arm model, trainees can not only master standardized puncture skills, but also enhance their confidence and clinical safety awareness in a risk-free environment.
