A black and white line drawing of a hand holding a syringe. The syringe is made of plastic and has a long, cylindrical body with a needle at the end. The needle is connected to a hose that extends from the top of the syringe to the bottom. The hose is attached to a small, rectangular device with a connector at the bottom, which is likely used to connect the device to a power source. The device appears to be a pressure gauge or a measuring instrument used to measure the pressure of a liquid or gas.
