Resonance high pressure syringe

The utility model is a high-pressure injector used for the inspection of magnetic resonance; the whole device consists of two parts including an injector body and an air pump. The full body part is made of the plastic, which mainly consists of a gas storage tank, a three-connecting air valve and a cylinder piston component. The three units are connected by a connecting tube, which can pass through the magnetic resonance inspecting room safely; the device is with the better magnetic field compatibility. The air pump is provided with an air-pressure meter and an air-transfer tube; the air-pressure meter can display the pressure of the output air; the air-transfer tube can be connected with the intake mouth of the injector body; the whole air pump is not equipped with the magnetic field compatibility. When being used, the air pump is put outside of the inspecting room.
