Detailed Description

The invention is further described with reference to the following figures and examples.

Examples

A head radiation protection device for CT scanning comprises a bed 1, wherein a brain shield 2 is installed at the end position of the bed 1, the end of the brain shield 2 is closed and perpendicular to the cross section of the length direction of the bed 1, an eye shield 3 is installed on the brain shield 2, and the eye shield 3 can move along the length direction of the bed 1.

Further, in this embodiment, the cross section of the eye shield 3 perpendicular to the length direction of the bed 1 is an inverted U shape, two sides of the end position of the bed 1 are both provided with sliding chutes 4 which are opened upwards, two sides of the eye shield 3 are respectively inserted into the two sliding chutes 4, and the eye shield 3 can slide along the sliding chutes 4. The eye shield 3 can slide along the length direction of the bed 1, so that the total protection length of the whole protection device can be adjusted, and the protection position can be flexibly selected.

Further, in this embodiment, the cross section of spout 4 is "T" type the gear 5 is installed to the lower extreme of spout 4 the both sides limit lower extreme of eye guard shield 3 all is provided with rack 6 install motor 7 on the both sides limit of the tip position of bed 1, motor 7 with gear 5 coaxial power is connected, gear 5 with rack 6 meshing is connected. The selection of 5 racks of gear 6 makes the slip of eye guard shield 3 be automatic state, when in actual use, can external wireless switch, the doctor directly controls the switch alright conveniently to the slide adjusting of eye guard shield 3, and is convenient simple.

When a patient only scans the brain, the brain shield 2 needs to be opened, so that two slots 8 are arranged at two sides of the end position of the bed 1, two side edges of the brain shield 2 are inserted into the slots 8, ear plates 9 are arranged at two sides of the lower end of the brain shield 2, the ear plates 9 are hinged at the end of the bed 1, and the hinged shaft is parallel to the width direction of the bed 1.
