Abstract

A first transport apparatus includes a deck for supporting a patient thereon and a lift mechanism supporting the deck. The deck is removable from the lift mechanism for use as a second transport apparatus or part of a second transport apparatus. The first transport apparatus further includes an electrically powered device at the first transport apparatus, and a user input device for wireless control of the electrically powered device, which is operable at or near the first transport apparatus and the second transport apparatus.

First claim

The invention claimed is:

1. An emergency medical services patient transport apparatus for transporting a patient and loading and unloading the patient into and out of an emergency medical services vehicle, said patient transport apparatus comprising:
a base having a plurality of wheels;
a deck support frame having a front end, a back end, and a footprint;
an articulatable deck supported by the deck support frame for supporting the patient thereon, the deck including a plurality of deck sections, the plurality of deck sections including a seat section, a back section, and a leg section, the seat section mounted to the deck support frame for movement with the deck support frame, the back section being pivotally mounted to the deck support frame adjacent the seat section, the leg section pivotally mounted to the deck support frame adjacent the seat section at the front end of the deck support frame; and
a lift assembly mounting the deck support frame to the base and being operable to raise and lower the deck support frame and the deck relative to the base between a raised transport height and a lowered loading height for loading the apparatus into the emergency medical services vehicle, the lift assembly being formed from a pair of upper X-frames and lower X-frames, each of the lower X-frames being mounted to the base and each of the upper X-frames being pivotally mounted to opposed sides of the deck support frame at or within the footprint of the deck support frame wherein the leg section is operable to pivot between a cot transport configuration and a chair configuration without interference with the lift assembly, and wherein the pair of upper X-frames and the pair of lower X-frames have telescoping legs wherein the lift assembly is configured to tilt the deck support frame and thereby tilt the articulatable deck relative to the base.

2. The patient transport apparatus according to claim 1 , wherein the lower X-frames are pivotally mounted to the base by first and second pairs of pivot connections, the first pair of pivot connections forming a sliding pivot connection with the base.

3. The patient transport apparatus according to claim 1 , wherein the base includes a track extending above the wheels.

4. The patient transport apparatus according to claim 3 , wherein the plurality of wheels comprise a pair of forward wheels generally located below the front end of the deck support frame and a pair of back wheels, and the track located between the forward wheels and located between the back wheels.

5. The patient transport apparatus according to claim 4 , wherein the track extends beyond the forward wheels.

6. The patient transport apparatus according to claim 4 , wherein the track extends beyond the back wheels.

7. The patient transport apparatus according to claim 4 , wherein the track comprises a pair of tracks.

8. An emergency medical services patient transport apparatus for transporting a patient and loading and unloading the patient into and out of an emergency medical services vehicle, said patient transport apparatus comprising:
a wheeled base;
a deck for supporting the patient thereon, the deck mounted relative to wheeled base; and
a pair of upper X-frames supporting the deck and a pair of lower X-frames pivotally connected to the upper X-frames, the lower X-frames mounted to the wheeled base, wherein when extended or contracted the upper and lower X frames raise or lower the deck relative to the base between a raised transport height and a loading height for loading the apparatus into the emergency medical services vehicle, and wherein the pair of upper X-frames and the pair of lower X-frames have telescoping legs wherein the upper and lower X frames are operable to tilt the deck relative to the base; and
the deck being reconfigurable between a cot configuration and a chair configuration and having a footprint, and the upper and lower X-frames being substantially within the footprint of the deck when the deck is in the chair configuration.

9. The patient transport apparatus according to claim 8 , further comprising a deck support frame, the deck mounted to the deck support frame, and the upper X-frames mounted to the deck support frame.

10. The patient transport apparatus according to claim 9 , further comprising a pair wheels mounted to the deck support frame.

11. The patient transport apparatus according to claim 10 , wherein the deck support frame has a front end and a back end, the deck including a back section, a seat section, and a leg section, and the leg section pivotally mounted the front end of the deck support frame.

12. The patient transport apparatus according to claim 11 , wherein the pair of wheels is mounted to the back end of the deck support frame.

13. The patient transport apparatus according to claim 11 , further comprising a pair of side rails, each side rail mounted at opposed sides of the seat section.

14. The patient transport apparatus according to claim 9 , wherein the lower X-frames are pivotally mounted to the base by first and second pairs of pivot connections, the first pair of pivot connections forming a sliding pivot connection with the base.

15. The patient transport apparatus according to claim 8 , wherein the deck has a length, further comprising an extendible head rest and/or extendible foot rest to thereby extend the length of the deck.

16. The patient transport apparatus according to claim 8 , wherein the base includes a track, the track extending above the wheels.

17. The patient transport apparatus according to claim 16 , wherein the wheeled base includes a pair of forward wheels and a pair of back wheels, the track located between the forward wheels and located between the back wheels.

18. The patient transport apparatus according to claim 16 , wherein the wheeled base includes a pair of forward wheels and a pair of back wheels, the track extending beyond the forward wheels.
