Abstract

Claims (41)

1. A system comprising:

a patient support apparatus including:

a base supporting a plurality of caster assemblies arranged for movement along floor surfaces,

an intermediate frame with a patient support deck for a patient,

an electrical distribution system,

one or more electrical devices including at least one actuator for moving the intermediate frame relative to the base, and

an energy storage device (ESD) configured to store energy to power the one or more electrical devices through the electrical distribution system;

a unit being independent from the patient support apparatus and including a charging station for coupling to and charging the ESD; and

a device including an output device, one or more processors, and a non-transitory computer-readable medium comprising instructions, which when executed by the one or more processors, are configured to provide information presentable with the output device relating to:

a remaining charge of the ESD, and

a proximity between the patient support apparatus and the unit.

2. The system of claim 1 , wherein the instructions, when executed by the one or more processors, are further configured to determine a location of the patient support apparatus and to determine a location of the unit.

3. The system of claim 2 , wherein the instructions, when executed by the one or more processors, are further configured to provide information presentable on the output device relating to directions to navigate the patient support apparatus to the unit.

4. The system of claim 2 , wherein the instructions, when executed by the one or more processors, are further configured to provide information presentable on the output device relating to a remaining charge of the ESD.

5. The system of claim 4 , wherein the instructions, when executed by the one or more processors, are further configured to determine the remaining charge of the ESD according to time based on a distance from to the unit.

6. The system of claim 1 , wherein the instructions, when executed by the one or more processors, are further configured to provide a notification on the output device regarding needed replacement of the ESD with a charged replacement ESD coupled to the charging station of the unit.

7. The system of claim 1 , wherein the instructions, when executed by the one or more processors, are further configured to determine the proximity between the patient support apparatus and the unit according to time and/or distance.

8. The system of claim 1 , wherein the device is further defined as a mobile computing device independent of the patient support apparatus and the unit; and

wherein the output device is further defined as a display.

9. The system of claim 1 , wherein the device is further defined as a user interface device operably coupled to the patient support apparatus.

10. The system of claim 1 , wherein the charging station is coupled to the unit.

11. The system of claim 1 , wherein the unit further comprises a docking system configured to enable docking between the patient support apparatus and the unit.

12. The system of claim 1 , wherein the unit is configured to autonomously interact with the patient support apparatus to remove the ESD from the patient support apparatus and/or to place a replacement ESD on to the patient support apparatus; and

wherein the unit comprises a robotic device being configured to remove the ESD and/or to place the replacement ESD.

13. The system of claim 12 , wherein the unit is configured to autonomously interact with the patient support apparatus to remove the ESD from the patient support apparatus and/or to place a replacement ESD on to the patient support apparatus; and

wherein the unit is mobile and configured to receive tracking information about the patient support apparatus to autonomously approach the patient support apparatus.

14. The system of claim 1 , wherein the ESD includes a casing having a first interface;

wherein the charging station of the unit comprises a second interface configured to engage the first interface to facilitate charging the ESD via the charging station; and

wherein the first and second interfaces are mechanical interfaces being configured to mechanically interlock.

15. The system of claim 1 , wherein the ESD includes electrical contacts; and

wherein the patient support apparatus includes a receptacle for housing the ESD and having electrical contacts coupled to the electrical distribution system and being configured to interface with the electrical contacts of the ESD to power the one or more electrical devices through the electrical distribution system.

16. The system of claim 15 , wherein the unit is further configured to autonomously remove the ESD from the receptacle and/or to autonomously place a replacement ESD into the receptacle.

17. The system of claim 16 , wherein the unit comprises a receptacle for housing the ESD and/or the replacement ESD; and

wherein the unit is further configured to autonomously place the ESD into the receptacle and/or to autonomously remove the replacement ESD from the receptacle.

18. The system of claim 17 , wherein the receptacle of the unit includes electrical contacts coupled to a power source of the charging station and being configured to interface with the electrical contacts of the ESD and/or with electrical contacts of the replacement ESD to enable the power source to electrically charge the ESD and/or the replacement ESD.

19. The system of claim 1 , wherein the patient support apparatus further comprises a second ESD being of a different type than the ESD and with the second ESD being connectable to the electrical distribution system to power the one or more electrical devices; and

wherein the second ESD is a Lithium ion battery or a supercapacitor.

20. The system of claim 19 , wherein the patient support apparatus further comprises a controller being configured to:

evaluate a state of the second ESD;

selectively disconnect the second ESD from the electrical distribution system in response to evaluating the state of the second ESD; and

selectively connect the ESD to the electrical distribution system to power the one or more electrical devices instead of the second ESD in response to selectively disconnecting the second ESD.
