Abstract

A prone positioning therapeutic bed comprises a base frame, a patient support platform rotatably mounted on the base frame for rotational movement about a longitudinal rotational axis, a drive system for rotating the patient support platform on the base frame, and an upright end ring at the head of the bed with a central opening for routing patient care lines and a removable upper section for improved access to a patient's head. The patient support platform preferably has pivotally mounted side rails that fold underneath the patient support platform and straps with strap connectors that indicate whether the straps are sufficiently tensioned. A direct, wired electrical connection between the patient support platform and the base frame allows full rotation of the patient support platform in either direction. A manually operable lever disengages the patient support platform from the drive system to allow manual rotation of the patient support platform.

Claims

1. A therapeutic bed comprising:

2. The therapeutic bed of claim 1 wherein the at least one prone support extension comprises a first section pivotally attached to a side of the patient support platform, wherein the first section extends upward from and substantially perpendicular to the patient support platform when the prone support extension is in the extended position, and underneath and substantially parallel to the patient support platform when the prone support extension is in the retracted position.

3. The therapeutic bed of claim 2, wherein the first section of the prone support extension comprises at least two rails.

4. The therapeutic bed of claim 2 wherein the prone support extension further comprises a second section connected to the first section, the second section extending substantially perpendicularly from the first section and substantially parallel to the patient support platform when the prone support extension is in the extended position.

5. The therapeutic bed of claim 4, wherein the second section of the prone support extension is pivotally connected to the first section.

6. The therapeutic bed of claim 4, wherein the prone support extension further comprises a third section connected to the second section, wherein one or more of the prone support cushions are mounted on the third section.

7. The therapeutic bed of claim 6, wherein the third section of the prone support extension comprises a hinge plate.

8. The therapeutic bed of claim 6, wherein the third section of the prone support extension is pivotally connected to the second section, so that the one or more prone support cushions mounted on the third section are operable to be folded inwardly toward the first section when the prone support extension is in the retracted position.

9. The therapeutic bed of claim 8, wherein the prone support extension further comprises a strap operable to retain the one or more prone support cushions mounted on the third section in the inwardly folded position.

10. The therapeutic bed of claim 1, further comprising a detent mounted to the patient support platform that is operable to hold the at least one prone support extension in the extended position.

11. The therapeutic bed of claim 10, where in the detent is also operable to hold the at least one prone support extension in the retracted position.

12. The therapeutic bed of claim 11, wherein the prone support extension is slidably mounted on a shaft adjacent a side of the patient support platform.

13. The therapeutic bed of claim 12, further comprising means for preventing the prone support extension from rotating with respect to the shaft.

14. The therapeutic bed of claim 12, further comprising:

15. The therapeutic bed of claim 1, further comprising a plurality of spaced-apart complementary pairs of prone support extensions pivotally mounted on opposite sides of the patient support platform, each pair of prone support extensions having an associated locking strap to releasably lock the prone support extensions together in the extended position.

16. A prone-positioning bed comprising:

17. The prone-positioning bed of claim 16 wherein the strap connector is slidably mounted on said patient support platform.

18. The prone-positioning bed of claim 16 wherein the indicator provides a visible indication of whether the strap is sufficiently tensioned.

19. The prone-positioning bed of claim 16 wherein the indicator provides an electrical signal representative of whether the strap is sufficiently tensioned.

20. The prone positioning bed of claim 19, further comprising:

21. A prone-positioning bed comprising:

22. The prone-positioning bed of claim 21, further comprising a compressible pad for engagement with the at least one prone support extension to control activation of the tape switch.

23. The prone positioning bed of claim 21, further comprising:

24. A therapeutic bed comprising:

25. The therapeutic bed of claim 24, wherein the motor is operable to provide controlled alternating rotational movement to the patient support platform about an arc of rotation that crosses the inverted prone patient position.
