This model is designed for intravenous injection training on the arm. It consists of an arm 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 arm, a bottle for simulated blood tank, a power cord for the motor, and a shield. With the fabric attached to the arm skin pad, the 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 manikin arm 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 after circulating the pad to see the water drops 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 arm skinpad and as result, it comes to another end of the tube.
There is also a version without the motor in case you are not available for electricity.
