Abstract

There is provided a patient support that may be adjustable in height, width, length or a combination thereof. The patient support may be useable with normal sized patients or with bariatric patients. The patient support has a variety of features to enhance operability and/or functionality, including a width adjustable caster frame, width adjustable deck portions, a width adjustable headboard and an extendible foot board to provide extra length. An enhanced lift mechanism can accommodate bariatric patients and alternative functionality in achieving deck positions improves patient comfort. Various parts of the patient support including deck panels and the footboard may be removed and replaced with ease without complicated connectors.

First claim

The invention claimed is:

1. A patient support apparatus for supporting a patient thereon, the patient support apparatus comprising:
a base;
a deck for supporting a mattress thereon; and
a lift mechanism for supporting the deck on the base, each of the base, the deck and the lift mechanism having a width, and the width of each of the base, the deck, and the lift being adjustable.

2. The patient support apparatus according to claim 1 , wherein the width of each of the base, the deck, and the lift mechanism is simultaneously adjustable.

3. The patient support apparatus according to claim 1 , wherein the base includes a base actuator to adjust the width of the base, and the deck including a deck actuator to adjust the width of the deck.

4. The patient support apparatus according to claim 1 , wherein the lift mechanism includes a pair of leg assemblies.

5. The patient support apparatus according to claim 4 , wherein each leg assembly of the pair of leg assemblies comprises lower and upper ends, the lower ends of each leg assembly being pivotally mounted relative to the base, and the upper ends of each leg assembly being pivotally mounted relative to the deck.

6. The patient support apparatus according to claim 5 , wherein the lower ends of each leg assembly are spaced apart by a spacing and the upper ends of each leg assembly are spaced apart by a spacing, the spacings between the lower ends of the leg assemblies and the spacings between the upper ends of the leg assemblies being adjustable to thereby adjust the width of the lift mechanism.

7. The patient support apparatus according to claim 5 , further comprising a deck frame having a width, the deck supported by the deck frame, and the width of the deck frame being adjustable.

8. The patient support apparatus according to claim 7 , wherein the upper ends of the leg assemblies are pivotally mounted to the deck frame.

9. The patient support apparatus according to claim 5 , further comprising a lower frame mounted in the base, and the lower ends of the leg assemblies being pivotally mounted to the lower frame.

10. The patient support apparatus according to claim 9 , wherein the lower frame includes guides for guiding the lower ends of the leg assemblies when the leg assemblies raise or lower the deck.

11. The patient support apparatus according to claim 10 , wherein the base has opposed frame members and the guides are angled relative to the opposed frame members wherein the lower ends of the leg assemblies move toward or away from each other when the lift mechanism lowers or raises the deck.

12. The patient support apparatus according to claim 1 , wherein the deck has a head end and a foot end, further comprising a barrier at the head end or the foot end, and the barrier having an adjustable width.

13. The patient support apparatus according to claim 12 , wherein the barrier has two movable sections.

14. The patient support apparatus according to claim 12 , further comprising side rails mounted to the deck, and the side rails moving with the adjustment of the width of the deck.

15. The patient support apparatus according to claim 14 , wherein the adjustable width of the barrier is adjustable to maintain a required spacing between the barrier and the side rails when the width of the deck is adjusted.

16. A patient support apparatus for supporting a patient thereon, the patient support apparatus comprising:
a base, the base having a plurality of caster wheel assemblies, each caster wheel assembly having a caster wheel mounted about a swivel axis and a rotational axis, and each caster wheel having an orientation about the swivel axis,
a deck for supporting a mattress thereon;
a lift mechanism for supporting the deck on the base, each of the base and the deck having a width, and the width of each of the base and the deck being adjustable; and
wherein the caster wheels are configured to adjust the orientation before the width of at least the base is adjusted.

17. The patient support apparatus according to claim 16 , wherein each respective caster wheel of the caster wheels includes a caster wheel actuator to adjust the orientation of the respective caster wheel.

18. The patient support apparatus according to claim 17 , further comprising a control system, the control system having a controller and a deck actuator in communication with the controller to adjust the width of the deck and a base actuator in communication with the controller to adjust the width of the base.

19. The patient support apparatus according to claim 18 , wherein the controller is in communication with the caster wheel actuator to control the orientation of the caster wheel actuator.

20. The patient support apparatus according to claim 16 , wherein the width of the lift mechanism is adjustable.

21. The patient support apparatus according to claim 18 , wherein the base comprises a caster frame.

22. The patient support apparatus according to claim 21 , further comprising a lower frame mounted in the caster frame, and the lift mechanism mounted relative to the base by the lower frame.

23. The patient support apparatus according to claim 18 , wherein the controller adjusts the widths of the deck and/or the base based on an input.

24. The patient support apparatus according to claim 20 , wherein the control system includes one or more sensors to detect an orientation of the patient support apparatus, and the control system adjusting at least one of the widths of the deck or the base based on the orientation of the patient support apparatus.

25. A patient support apparatus for supporting a patient thereon, the patient support apparatus comprising:
a base;
a deck for supporting a mattress thereon; and
a headboard supported relative to the deck, the headboard having first and second headboard sections, each of the first and second headboard sections having an outwardly facing surface, the second headboard section being moveable between a first position wherein the outwardly facing surfaces of the first and second headboard sections are generally coplanar with each other and contiguous and a second position spaced along the first headboard section wherein the outwardly facing surfaces of the first and second headboard sections are spaced apart, and the first and second headboard sections configured to leave no gap therebetween when the second headboard section is in the first or second position.

26. The patient support apparatus according to claim 25 , wherein each of the first and second headboard sections has a mount for mounting the headboard relative to the deck.

27. The patient support apparatus according to claim 26 , wherein each of the mounts comprises downwardly extending mounting posts.

28. The patient support apparatus according to claim 26 , further comprising a deck frame for supporting the deck, wherein the first and second headboard sections are mounted to the deck frame.

29. The patient support apparatus according to claim 28 , further comprising a headboard supporting base mounted to the deck frame, and the mounts of the first and second headboard sections releasably mounting the headboard to the headboard supporting base.

30. The patient support apparatus according to claim 29 , wherein the mounts of the first and second headboard sections and the headboard supporting base are configured to allow
