Abstract

There is disclosed a support surface which is particularly suited for supporting a patient and permitting X-rays of the patient to be taken. The support surface comprises at least two substantially rigid support elements coupled together by a flexible joining element such that relative movement between the support elements can take place. The support elements and flexible joining elements are radio-lucent with at least an area through which X-rays are (in use of a support surface) to pass, being of such relative thicknesses and composition that said area is of substantially uniform radio-lucence.

Claims

1. A patient support surface, which comprises:

at least two substantially rigid support elements coupled together by a flexible joining element having such a construction that relative movement between the support elements can take place, and

an X-ray suppressant material applied as required to achieve substantially uniform radiolucence in at least that area of the support surface normally occupied by the patient'"'"'s body located thereon.

2. A support surface as claimed in claim 1, wherein the support elements comprise panels formed from compressed wood fiber board and the joining element comprises an area of flexible material spanning between adjacent edges of said panels.

3. A support surface as claimed in claim 1 or 2 wherein the joining element is bendable in only one direction such that as the angle between the support elements diminishes the joining element curves through a diminishing radius.

4. A support surface as claimed in claim 3 wherein the joining element comprises a resin bonded carbon fiber laminate.

5. A support surface as claimed in claim 4 wherein portions of the area of flexible material are fixedly mounted in said support elements.

6. A support surface as claimed in claim 5 wherein a filler material is provided in the area between adjacent edges of the support elements so as to provide a support surface.

10. A support surface as claimed in claim 1 or 7 which comprises a plurality of said substantially rigid support elements joined by said flexible joining elements to form the patient support surface, said support surface being in combination with a support frame to form a piece of one of emergency and hospital equipment.

11. Emergency or hospital equipment as claimed in claim 10 wherein the support frame comprises means for controlled articulated movement of at least one support element relative to a next adjacent support element about the flexible coupling formed by the flexible element joining said support elements.

7. A patient support surface, which comprises:

at least two substantially rigid support elements coupled together by a flexible joining element having such construction that relative movement between the support elements can take place while maintaining substantially uniform radiolucence in at least that area of the support surface normally occupied by a patient'"'"'s body located thereon, wherein said rigid support elements comprise panels formed from compressed wood fiber board and the joining element comprises a resin bonded carbon fiber laminate spanning between adjacent edges of said panels.

8. A support surface as claimed in claim 7, which comprises an X-ray suppressant material applied to at least one of the flexible and support elements for achieving said substantially uniform radiolucence.

9. A support surface as claimed in claim 7 or 8 which comprises a filler material provided in the area between adjacent edges of the support elements so as to provide a continuous surface.

12. A patient support surface which comprises:

at least two rigid support elements coupled together by a unitary joining element of less cross-sectional thickness than said support elements and being bendable in one direction to enable relative movement between the rigid support elements to take place, and

a support frame with which said support surface is mounted, said support frame being free of any frame elements extending immediately beneath that area of the support surface on which a patient would normally be located, said support surface being of substantially uniform radiolucence in at least said area, such that an X-ray cassette is positionable beneath said support surface and a patient may be X-rayed while located on said support surface.

13. A patient support surface as claimed in claim 12 which comprises X-ray suppressant material applied to at least one of the flexible and support elements for achieving said substantially uniform radiolucence in at least said area of the support surface.

14. A patient support surface as claimed in claim 12 or 13 wherein the support elements comprise panels formed from compressed wood fiber board and the joining element comprises resin bonded carbon fiber laminate with portions of said area of flexible material being fixedly mounted in said panels.

15. A patient support surface as claimed in claim 12 or 13 which comprises rails provided beneath the support surface for the sliding location of an X-ray cassette.
