Patent number: 7905233Abstract: A patient support incorporates a patient retention device includes frame, a rotatable shaft, a torque-producing device, and a flexible restraint member. The shaft has a cantilevered portion that extends from the frame and windably receives the flexible restraint member at the cantilevered portion. Optionally, a winding member is releasably coupled to the cantilevered portion of the shaft for receiving the flexible restraint member. The winding member is non-rotatable relative to the shaft, and is readily removable and replaceable. The torque-producing device applies a torque to the shaft to wind the flexible restraint member onto the shaft or winding member.Type: GrantFiled: April 11, 2008Date of Patent: March 15, 2011Assignee: Stryker CorporationInventor: Christopher J.

Patent number: 7062805Abstract: A wheeled carriage for supporting a patient includes a patient support with head and foot ends and a wheeled base supported by castered wheels. Auxiliary wheels secured to an auxiliary wheel support structure are suspendedly mounted to the wheeled base. A control apparatus includes manipulative members, such as foot pedals at the head and foot ends and at the lateral sides of the wheeled carriage. The side foot pedals are supported by a transverse control shaft. The transverse control shaft extends through apertures in the auxiliary wheel support structure. Wheel bearing devices rotatably attach the auxiliary wheels relative to the transverse control shaft. A linkage arrangement enables the side foot pedals to physically move with the auxiliary wheels during movement between deployed and stowed positions.Type: GrantFiled: September 17, 2003Date of Patent: June 20, 2006Assignee: Stryker CorporationInventors: Christopher J.

Patent number: 6752224Abstract: A wheeled carriage for supporting a patient in a substantially horizontal position includes a patient support having head and foot ends and a wheeled base supported by castered wheels. Auxiliary wheels are suspendably mounted on a wheel support structure with the axis of the auxiliary wheels spaced from a midpoint of the wheeled base. A control apparatus controls the wheel support structure to move the auxiliary wheels between a first deployed position whereat castered wheels at one end of the carriage are elevated from a floor surface, and a second stored position with the auxiliary wheels out of engagement with the floor surface. The wheeled carriage includes a drive motor for powering the auxiliary wheels. A drive member applies force to a load cell on the wheeled carriage. The load cell outputs a drive signal to drive the auxiliary wheels.Type: GrantFiled: February 28, 2002Date of Patent: June 22, 2004Assignee: Stryker CorporationInventors: Christopher J.

Patent number: 6289537Abstract: A patient support having a frame supporting a patient supporting surface as well as supporting a pair of foot rest mechanisms thereon. The pair of foot rest mechanisms are each selectively movable from stowed positions beneath the patient supporting surface to deployed positions thereof which straddle a drop leaf foot section forming a part of the patient supporting surface. As the drop-leaf foot section is moved to a vertically upright position, a space between the two foot rest mechanisms is available for physician use. Further, as the drop leaf foot section is moved in the vertically upright position toward the floor, a mechanism is provided for preventing contact of the foot end of the drop leaf foot section with the floor.Type: GrantFiled: February 9, 2000Date of Patent: September 18, 2001Assignee: Stryker CorporationInventors: Christopher J.

Patent number: 5343581Abstract: A drive mechanism for a hospital bed effects relative vertical movement of a base and a patient litter. The drive mechanism includes spaced, telescoping threaded screw assemblies, which are driven by a single electric motor through a train of gears having helical teeth oriented to offset inherent frictional forces of the screw assemblies. A support for the motor and a component of the drive train are made of electrically nonconductive materials to electrically isolate the motor, and are arranged to damp vibrations produced by the motor. Two coiled electrical cords extend between the base and patient litter, and are each received in a recess in the patient litter when the patient litter is adjacent the base. A sensor arrangement provides an electrical signal indicative of the relative vertical positions of the patient litter and base, and a manual drive arrangement is provided to permit the gear train to be manually driven.Type: GrantFiled: October 21, 1992Date of Patent: September 6, 1994Assignee: Stryker CorporationInventors: Gary L. Bartley, Christopher J. Hopper

Patent number: 5329657Abstract: A hospital bed includes an articulatable patient support with a fowler portion movable between horizontal and inclined positions relative to a frame of the bed. A reversible electric drive motor is supported on the frame of the bed and, through a reduction gearing arrangement and a releasible coupling mechanism, can rotatably drive a threaded shaft. A nut engages and is held against rotation with the shaft, and a linkage arrangement couples the nut to the fowler portion to effect reciprocal movement of the fowler portion in response to reciprocal movement of the nut along the shaft. A manual release is provided on the fowler portion and, when actuated, disengages the releasible coupling mechanism so that the threaded shaft is free to rotate independently of the motor and gearing arrangement.Type: GrantFiled: October 21, 1992Date of Patent: July 19, 1994Assignee: Stryker CorporationInventors: Gary L. Bartley, Christopher J. Hopper, Louis A. Haddock, Jr., John S. Messner
