The application provides a
venipuncture training and examination
model simulation arm module, which simulates the
forearm structure of an adult, and is sequentially provided inside a
simulation arm body from outside to inside with a
simulation skin layer made of flexible
high polymer elastic material and detachably installed on the outer surface of the
simulation arm, a simulation fat layer provided inside the simulation
skin layer and used for simulating the buffer resistance of
subcutaneous fat tissue, a simulation
muscle layer provided inside the simulation fat layer and used for supporting the arm shape and providing
puncture resistance, and a simulation
venous vessel network embedded between the simulation fat layer and the simulation
muscle layer according to the real anatomical running, wherein the simulation
skin layer, the simulation fat layer, the simulation
muscle layer and the simulation
venous vessel network are all configured as detachable modules, and can be replaced with combinations of different thickness,
hardness and venous elasticity parameters according to the training requirements.
