Abstract
A patient support system comprises a patient support apparatus for patients. The patient support apparatus comprises a base and a patient support surface supported by the base. The patient support apparatus also comprises side rails that move between raised and lowered positions. One or more actuators are coupled to each of the side rails. A controller communicates with the actuators to raise and lower the side rails, either without any manual assistance from the user, or with manual assistance from the user.
Claims16
A patient support apparatus for supporting a patient, said patient support apparatus comprising:
- a support structure;
- a side rail movable relative to said support structure between a raised position and a lowered position, said side rail comprising an interior;
- a support arm assembly coupling said side rail to said support structure, said support arm assembly including:
- a first support arm pivotally coupled to said side rail about a first side rail pivot axis and pivotally coupled to said support structure about a first frame pivot axis, and
- a second support arm spaced from said first support arm, said second support arm pivotally coupled to said side rail about a second side rail pivot axis and pivotally coupled to said support structure about a second frame pivot axis;
- an actuator disposed at least partially within said interior of said side rail and configured to move said side rail between said raised position and said lowered position;
- an input device for generating an input signal;
- and
- a controller in communication with said actuator and said input device and configured to receive said input signal from said input device to control said actuator based on said input signal.
