Abstract: The invention provides a training aid for teaching venous or arterial puncture and line placement. It comprises model pressure-loadable veins and arteries having lifelike properties, including tactile sensation and accurate sonographic images that enable a trainee to learn to locate and access target vessels in real time by ultrasound. The present invention advantageously provides the trainee with instant feedback of having accessed the correct or wrong blood vessel by withdrawing different color fluids. The combination of realistic modeling of the vasculature, real-time feedback, and risk-free training environment allows for the development of proficiency in ultrasound-guided invasive medical techniques.
