Abstract
Various methods and systems are provided for patient transfer using a patient table with lockable casters. In one example, a method includes adjusting locking of the lockable casters sequentially in response to an indication of reversing of the patient table. The sequential caster locking may be based on acceleration, velocity changes, or user interface forces. In another example, the system may include sensors to detect operator input and a controller to adjust caster locking accordingly.
Claims18
A method for controlling a patient table having a plurality of lockable casters, comprising:
- adjusting locking of the lockable casters sequentially in response to an indication of reversing of the patient table, and
- reducing force assist for a first duration based on a magnitude of the indication of reversing being less than a first threshold and reducing force assist for a second duration based on the magnitude of the indication of reversing being greater than the first threshold.
A method for controlling a patient table having a plurality of lockable casters, comprising:
- adjusting locking of the lockable casters sequentially in response to an indication of reversing of the patient table, and
- simultaneously unlocking the lockable casters in response to an indication of one of a multiple operator condition and deceleration to stop for less than a second threshold.
A method for controlling a patient table having a plurality of lockable casters, comprising:
- during a first operation, unlocking the lockable casters sequentially;
- and
- during a second operation, unlocking the lockable casters concurrently,
- wherein the first operation includes a first indication of reversing of the patient table and the second operation includes one of a second indication of multiple user interface forces and deceleration to stop for less than a threshold.
A method for controlling a patient table having a plurality of lockable casters, comprising:
- during a first operation, unlocking the lockable casters sequentially;
- during a second operation, unlocking the lockable casters concurrently;
- and
- reducing force assist for a duration during the first operation, and maintaining force assist during the second operation.
A patient transfer system, comprising:
- a medical imaging device;
- a patient table selectively docking to the medical imaging device;
- a plurality of lockable casters rotatably coupled to the patient table;
- a sensor coupled to the patient table;
- a controller communicatively coupled to the sensor and to the lockable casters;
- and
- a memory storing executable instructions that, when executed, cause the controller to:
- receive sensor signals from the sensor;
- unlock the lockable casters sequentially during a first operation;
- unlock the lockable casters concurrently during a second operation, and
- reduce force assist for a duration during the first operation, and maintain force assist during the second operation.
