A medical dummy, also known as a medical mannequin, is a lifelike model used for training healthcare professionals. These dummies simulate human anatomy and physiological responses, allowing students and practitioners to practice procedures, such as CPR or surgical techniques, in a safe environment. Medical dummies come in various forms, from basic models for basic skills to advanced versions equipped with technology that mimics real-life medical conditions. They are essential tools in medical education, helping to improve the skills and confidence of future doctors, nurses, and other healthcare providers.
