摘要：
A wheeled carriage for supporting a patient has a wheeled base having frame members supporting a plurality of caster wheel assemblies and a braking system. A moveable brake lock assembly, a brake lock actuator, and a swivel lock receiver are operatively connected to one of the caster wheel assemblies to define a locking caster wheel assembly. The brake lock assembly comprises an actuating member, a swivel lock member, and a brake member that are interconnected as a unit for simultaneous movement. The brake lock actuator is operable to selectively move the brake lock assembly into an engaged position via engagement with the actuating member such that the swivel lock member engages the swivel lock receiver and the brake member contacts a wheel of the locking caster wheel assembly thereby preventing rotation and swiveling of the wheel.
