Abstract

A radiation protection shield for protecting medical personnel from radiation being applied to a patient positioned on a table. The shield includes a frame and a primary screen including a radiation-resistant material connected to said frame.

Claims

1. A radiation protection shield for protecting medical personnel from radiation being applied to a patient positioned on a table, the shield comprising:

a frame; and

a primary screen including a radiation-resistant material connected to said frame.

2. A radiation protection shield as set forth in claim 1 wherein the primary screen includes a lead-impregnated acrylic.

3. A radiation protection shield as set forth in claim 1 further comprising a plurality of rollers attached to a bottom of the frame to allow the lower shield to move along a floor that the shield is positioned on during use of the radiation protection shield.

4. A radiation protection shield as set forth in claim 3 wherein said rollers are lockable to restrict the rollers from moving thereby limiting movement of the lower shield.

5. A radiation protection shield as set forth in claim 1 further comprising a secondary screen slidably connected to the primary screen so the secondary screen can move up and down with respect to the primary screen.

6. A radiation protection shield as set forth in claim 5 wherein the secondary screen includes a lead-impregnated acrylic.

7. A radiation protection shield as set forth in claim 5 wherein:

the primary screen and secondary screen are curved forming an inner concave surface and an outer convex surface opposite the concave surface; and

the inner surface is positioned adjacent the radiation source during use of the system.

8. A radiation protection shield as set forth in claim 1 further comprising a hand rail connected to said primary screen to facilitate moving of the lower shield.

9. A radiation protection shield as set forth in claim 1 further including a toe flange extending downward from the primary screen.

10. A radiation protection shield as set forth in claim 1 further comprising a kick plate positioned adjacent a lower edge of the shield for protecting the primary screen and for medical personnel to use to move the lower shield.

11. A radiation protection shield as set forth in claim 1 further comprising an upper flange extending from a top region of the shield to form a right angle with the primary screen.

12. A radiation protection shield as set forth in claim 5 further comprising an upper flange extending from a top region of the shield to form a right angle with the secondary screen.

13. A radiation protection shield as set forth in claim 12 further comprising an upper shelf extending from the top region of the shield adjacent said upper flange to form a right angle with the secondary screen.

14. A radiation protection shield as set forth in claim 13 wherein said upper shelf extends farther from the secondary screen than the upper flange extends from the secondary screen.

15. A radiation protection shield as set forth in claim 13 wherein the upper shelf is positioned adjacent an end of said shield.

16. A radiation protection shield as set forth in claim 15 further comprising an upper shelf extending from a top region of the shield.

17. A radiation protection shield as set forth in claim 16 wherein said shelf includes a lead-impregnated acrylic.

18. A radiation protection shield as set forth in claim 5 wherein:

the secondary screen is connected to generally vertical rods; and

the frame includes sleeves receiving said rods.

19. A radiation protection shield as set forth in claim 18 further comprising springs attached to the frame adjacent said sleeves for providing an upward force to the secondary screen by way of said rods.

20. A radiation protection shield as set forth in claim 18 further comprising a locking mechanism attached to the frame adjacent said sleeves for selectively locking the rods in place in the sleeves thereby locking the secondary screen in place with respect to the primary screen.

21. A radiation protection shield as set forth in claim 1 wherein said primary screen includes a lead-impregnated acrylic.

22. A radiation protection shield as set forth in claim 1 further comprising a secondary screen telescopically connected to the primary screen so the secondary screen can move up and down with respect to the primary screen.

23. A radiation protection shield for protecting medical personnel from radiation being applied to a patient positioned on a table, the shield comprising multiple screens telescopically connected to each other in a vertical direction so that an overall height of the shield can be selectively adjusted during use of the shield.
