This hand model is designed for intravenous injection training. It consists of a hand skin pad with a vein buried inside at the anatomically right position and shape, a motor for simulating the circulation of the blood flow through the hand, a bottle for simulated blood tank, a power cord for the motor, and a shield. With the fabric attached to the hand skin pad, users can have a more realistic practice experience by role-playing. There is a shield included to protect the user who wears the simulator from an unexpected puncture accident. A single person also can practice intravenous injection using the mannequin hand model.
The direction of the water pump is, the input tube near the bottle. The input tube should be sinking in the water and the output tube needs to be hanging in the air to see the water drops after circulating the pad which proves the water flow.
To drain, please pull the input tube in the air while the pump is still on. You can find the air goes into the pump to the hand skin pad and as result, it comes to another end of the tube.
