Abstract

A modular drive device for driving a first driven module of a first emergency patient motion device or a second driven module of a second emergency patient motion device, the first driven module being different from the second driven module. The modular drive device comprises a motor, and an output device operatively coupled to and drivable by the motor. The output device transmits mechanical force from the motor to the first driven module when said output device is coupled to the first emergency patient motion device and from the motor to the second driven module when said output device is coupled to the second emergency patient motion device. The modular drive device further comprises a controller operable in a first motor mode and a second motor mode. The first motor mode corresponding to the first driven module, and the second motor mode corresponding to the second driven module.

First claim

What is claimed is:

1. A modular drive device for driving a first driven module of a first emergency patient motion device or a second driven module of a second emergency patient motion device, the first driven module having different drive requirements from the second driven module, said modular drive device comprising:
a motor having an operation parameter;
an output device operatively coupled to and drivable by said motor to transmit mechanical force from said motor to the first driven module when said output device is coupled to the first emergency patient motion device and from said motor to the second driven module when said output device is coupled to the second emergency patient motion device, said output device having a drive parameter;
a mount coupler coupled to said output device and configured to removably couple said modular drive device to each of the first emergency patient motion device and the second emergency patient motion device; and
a controller in communication with one of said motor and said output device, said controller comprising an identification module configured to identify whether said modular drive device is coupled to the first emergency patient motion device or the second emergency patient motion device, with said controller being operable in a first motor mode when coupled to the first emergency patient motion device and a second motor mode when coupled to the second emergency patient motion device,
wherein in said first motor mode, said controller provides a first signal to one of said motor and said output device to control said motor or said output device based on the drive requirements of the first driven module, and wherein in said second motor mode, said controller provides a second signal to one of said motor and said output device based on the drive requirements of the second driven module.

2. A modular drive device according to claim 1 , further comprising a housing and an energy storage device, said energy storage device configured to be removably mounted to said housing, said energy storage device configured to provide energy to said motor and said controller.

3. A modular drive device according to claim 1 , further comprising a memory device, wherein said first motor mode of said controller corresponds to a first set of target parameters, wherein said second motor mode of said controller corresponds to a second set of target parameters, and wherein said first set of target parameters and said second set of target parameters are stored in said memory device, and wherein said controller is configured to control one of said motor and said output device to one of said first set of target parameters and said second set of target parameters.

4. A modular drive device according to claim 3 , wherein said controller is configured to automatically control one of said motor and said output device based on said identification module.

5. A modular drive device according to claim 1 , wherein said operation parameter of said motor is selected from the group consisting of: speed, torque, direction, and combinations thereof.

6. A modular drive device according to claim 1 , further comprising a user input device configured to control operation of the first driven module and the second driven module when said modular drive device is coupled to one of the first emergency patient motion device and the second emergency patient motion device.

7. A modular drive device according to claim 1 , wherein said operation parameter of said motor and said drive parameter of said output device correspond to a characteristic of patient motion effected by the first and second emergency patient motion devices.

8. A reconfigurable emergency patient motion system, said system comprising:
a modular drive device comprising:
a motor,
an output device operatively coupled to said motor, and
a mount coupler coupled to said output device;

a first emergency patient motion device comprising:
a first driven module having a first drive requirement and configured to perform a first patient motion function, and
a first drive module mounting assembly comprising a first drive mount and a first drive member; and

a second emergency patient motion device comprising:
a second driven module having a second drive requirement and movable to perform a second patient motion function, and
a second drive module mounting assembly comprising a second drive mount and a second drive member;

wherein said mount coupler is configured to be removably coupled to said first drive mount and said second drive mount such that said modular drive device powers said first driven module when said modular drive device is coupled to said first emergency patient motion device and said modular drive device powers said second driven module when said modular drive device is coupled to said second emergency patient motion device; and
a controller in communication with one of said motor and said output device, said controller comprising an identification module configured to identify whether said modular drive device is coupled to said first emergency patient motion device or said second emergency patient motion device, with said controller being operable in a first motor mode when coupled to said first emergency patient motion device and a second motor mode when coupled to said second emergency patient motion device, wherein in said first motor mode, said controller provides a first signal to one of said output device based on the drive requirements of said first driven module, and wherein in said second motor mode, said controller provides a second signal to one of said motor and said output device based on the drive requirements of said second driven module.

9. A reconfigurable emergency patient motion system according to claim 8 , wherein each of said first and second emergency patient motion devices is independently selected from the group consisting of a cot, a stair climber, a backboard lifter, a patient lift, and a transfer device.

10. A reconfigurable emergency patient motion system according to claim 8 , wherein said first emergency patient motion device is different from said second emergency patient motion device.

11. A reconfigurable emergency patient motion system according to claim 10 , wherein said first drive mount is the same as said second drive mount.

12. A reconfigurable emergency patient motion system according to claim 8 , wherein said first signal comprises a 100% duty cycle pulse width modulation signal; and
wherein said second signal comprises a 50% duty cycle pulse width modulation signal.
