Abstract

A bed for use with a patient coupled to a medical device via at least one patient care line is provided. The bed includes a frame including at least one movable patient support section and an actuator coupled to the movable patient support section. The actuator is operable to move the movable patient support section. The bed also includes control circuitry that is coupled to the actuator to command operation of the actuator. The control circuitry ceases operation of the actuator in response to receiving a signal indicative of an unwanted condition of the at least one patient care line.

Claims

1. A patient support apparatus for use with a patient coupled to a medical device via at least one patient care line, the patient support apparatus comprising

a frame including at least one movable patient support section,

an actuator coupled to the at least one movable patient support section and operable to move the at least one movable patient support section,

a user interface facing away from the patient and that is used by a caregiver to signal operation of the actuator to move the at least one movable patient support section, and

control circuitry coupled to the actuator to command operation of the actuator in response to use of the user interface by the caregiver, wherein during movement of the actuator in response to use of the user interface by the caregiver, the control circuitry ceases operation of the actuator in response to receiving a signal indicative of an unwanted condition of the at least one patient care line.

2. The patient support apparatus of claim 1, wherein the unwanted condition of the at least one patient care line comprises unwanted tensioning of the patient care line.

3. The patient support apparatus of claim 1, wherein the unwanted condition of the at least one patient care line comprises kinking of an IV fluid line.

4. The patient support apparatus of claim 1, wherein the unwanted condition of the at least one patient care line comprises blockage of an IV fluid line.

5. The patient support apparatus of claim 1, wherein the signal indicative of the unwanted condition is communicated to the control circuitry via a wired connection between the patient support apparatus and the medical device.

6. The patient support apparatus of claim 1, wherein the signal indicative of the unwanted condition is communicated to the control circuitry via a network of a healthcare facility.

7. The patient support apparatus of claim 1, wherein the signal indicative of the unwanted condition is communicated to the control circuitry wirelessly.

8. The patient support apparatus of claim 7, wherein the control circuitry comprises an acoustic sensor that receives sound waves emanating wirelessly from an audible alarm of the medical device.

9. The patient support apparatus of claim 1, further comprising a line management device that supports at least a portion of the patient care line and the line management device having a sensor that senses unwanted tensioning of the patient care line to produce the signal.

10. The patient support apparatus of claim 9, wherein the line management device comprises a plurality of upstanding fingers and the sensor is coupled to at least one of the plurality of upstanding fingers.

11. The patient support apparatus of claim 10, wherein the frame comprises a socket, the line management device comprises a post configured for receipt in the socket, the post having a first electrical connector coupled to the sensor, and the socket having a second electrical connector coupled to the control circuitry.

12. The patient support apparatus of claim 11, wherein the first and second electrical connectors mate together automatically as a result of insertion of the post into the socket.

13. The patient support apparatus of claim 9, wherein the sensor comprises a strain gage.

14. The patient support apparatus of claim 9, wherein the sensor comprises a force sensitive resistor element.

15. The patient support apparatus of claim 1, further comprising a line management device that supports at least a portion of the patient care line, the frame having a socket configured for receipt of a coupling portion of the line management device therein, and further comprising a sensor situated between the socket and the coupling portion, the sensor producing the signal.

16. The patient support apparatus of claim 15, wherein the sensor is mounted to the socket.

17. The patient support apparatus of claim 15, wherein the sensor comprises a strain gage.

18. The patient support apparatus of claim 15, wherein the sensor comprises a force sensitive resistor element.

19. The patient support apparatus of claim 1, wherein the at least one movable patient support section comprises at least one of a head section, a seat section, a thigh section and a foot section.

20. The patient support apparatus of claim 1, wherein the actuator comprises one of a head section motor, a thigh section motor, a foot section motor, and an elevation system motor.

21. The patient support apparatus of claim 1, further comprising a mattress having a portion supported on the at least one movable patient support section.

22. The patient support apparatus of claim 1, wherein the at least one movable patient support section is part of a patient support deck that is movable between a horizontal position in which the patient is supported in a lying down position and a chair egress position in which the patient is supported in a sitting up position.
