PURPOSE: A semi-automatic shield door for an MRI shield room is provided to reduce manufacturing costs by manufacturing a shielding structure without power. CONSTITUTION: A semi-automatic shield door for an MRI shield room comprises a door frame(100), a shield door(200), and a semi-automatic shield unit(300). The door frame is formed at the entrance of an MRI shield room. The shield door is drawn into/out of the door frame. The semi-automatic shield unit is composed of a guide, a silicon rubber hose, an air controller, and a finger plate. The silicon rubber hose is received in the tunnel of the guide and is expanded and contracted by air injected through a through hole. The air controller injects air to the silicon rubber hose. The finger plate touches a door rail(110) of the door frame and shields the bottom of a door body. |
