Upper Limb Nerve Injury Diagnosis and Inspection Training Simulator

■  In addition to using advanced sensors and 4 sets of microcomputer voice circuits for light indication, all four arms are equipped with high-quality speakers, automatic voice prompts, and four people can operate simultaneously to improve teaching effectiveness by four times.
■  Use the pain inspection needle in the percussion hammer, and each group of students will use the acupuncture method to check the corresponding number of simulated forearm and hand pain according to teaching and assessment needs. The speaker in the arm with normal pain will emit a "painful" sound, and the controller light of that number will display green. The speaker in the arm with no pain will emit a "painless" sound. Determine the type of nerve damage based on the different areas of pain sensation impairment.
