Abstract

A patient support system includes a patient support apparatus and a powered device mounted relative to the patient support apparatus and an electrical circuit to power the powered device, with the electrical circuit having a wireless power receiver to inductively couple to and transfer electrical energy from a wireless power transmitter when the wireless power receiver is in proximity to the wireless power transmitter.

Claims (27)

1. A patient support apparatus comprising:

a patient support deck for supporting a patient thereon;

a wireless power receiver operable to inductively couple and receive electrical energy from a wireless power transmitter when the wireless power transmitter is transmitting power wirelessly in proximity to the wireless power receiver; and

an electrically powered device or subsystem operably coupled to the wireless power receiver, the electrically powered device or subsystem configured to receive power from the wireless power receiver based on the electrical energy received by the wireless power receiver from the wireless power transmitter.

2. The patient support apparatus according to claim 1 , comprising an impedance matching circuit to improve a resonant frequency match between the wireless power receiver and the wireless power transmitter.

3. The patient support apparatus according to claim 1 , wherein the wireless power receiver includes a wireless power receiving coil.

4. The patient support apparatus according to claim 1 , in combination with a vehicle, the wireless power transmitter mounted in the vehicle.

5. The patient support apparatus according to claim 4 , wherein the patient support apparatus includes an emergency cot, and the emergency cot includes the patient support deck and a base supporting the patient support deck, and the electrically powered device includes an elevation mechanism for moving one of the patient support deck and the base relative to the other of the patient support deck and the base.

6. The patient support apparatus according to claim 5 , in combination with a loading and unloading apparatus mounted in the vehicle, the wireless power transmitter mounted and located to align with the wireless power receiver of the emergency cot when the emergency cot is loaded onto and fully retracted into the vehicle by the loading and unloading apparatus.

7. The patient support apparatus according to claim 1 , wherein the patient support apparatus includes a head end and a foot end, and wherein the wireless power receiver is mounted at or adjacent the foot end of the patient support apparatus.

8. The patient support apparatus according to claim 1 , wherein the patient support apparatus includes a head end and a foot end, and wherein the wireless power receiver is mounted at or adjacent the head end of the patient support apparatus.

9. A patient support system for a system component comprising:

a power supply circuit;

a wireless power transmitter operatively coupled to the power supply circuit, the wireless power transmitter configured for inductively coupling and transferring electrical energy to a wireless power receiver of the system component when the wireless power receiver is in proximity to the wireless power transmitter; and

an alignment structure operable to align the wireless power transmitter with the wireless power receiver of the system component.

10. The patient support system of claim 9 wherein the alignment structure is an engagement structure operable to engage the system component.

11. The patient support system of claim 10 wherein the engagement structure is operable to facilitate maintaining a position of the wireless power receiver of the system component in proximity to the wireless power transmitter.

12. The patient support system according to claim 9 , wherein the power supply circuit includes an impedance matching circuit.

13. The patient support system according to claim 12 , wherein the impedance matching circuit is configured to affect a frequency of applied current to the wireless power transmitter to adjust a frequency of the wireless power transmitter.

14. The patient support system of claim 9 wherein the alignment structure includes an arm assembly configured to mount relative to an emergency vehicle, the arm assembly configured to secure the system component in the emergency vehicle.

15. The patient support system according to claim 14 , wherein the arm assembly includes a movable arm, and the patent support system includes an electrically powered device configured to move the movable arm.

16. The patient support system according to claim 14 , wherein the arm assembly includes a pair of stationary arms configured to secure the system component in the emergency vehicle.

17. The patient support system according to claim 9 , comprising a track, the alignment structure mounted for movement along the track between an extended loading or unloading position to engage or disengage from the system component and a fully retracted position along the track.

18. The patient support system according to claim 9 , comprising a second power supply circuit with a second wireless power receiver to inductively couple to and transfer electrical energy from a second wireless power transmitter when the second wireless power receiver is in proximity to the second wireless power transmitter.

19. The patient support system according to claim 18 , wherein the second wireless power receiver is mounted relative to and moves with the alignment structure.

20. The patient support system according to claim 19 , in combination with a vehicle, the vehicle including the second wireless power transmitter operable to inductively transfer power to the second wireless power receiver when aligned with the second wireless power transmitter.

21. The patient support system according to claim 9 , wherein the system component is a loading and unloading device or a patient support apparatus.
