A transmission device for lifting a sickbed is fixed on a head mounting or a bed end of the sickbed and contains: a gear seat, a cover, a power input assembly, and a power output assembly. The gear seat includes a first conduit, a second conduit, a first opening, and a receiving orifice. The cover is covered on the first opening of the gear seat. The power input assembly includes an input shaft and a first bevel gear. The power output assembly includes an output shaft, a second bevel gear, and a support element. The support element is rotatably connected with the output shaft. The support element has multiple reinforcement ribs surrounding around an outer wall of the support element and configured to abut against an abutting fence of the second conduit, and the second bevel gear meshes with the first bevel gear.

A patient transport apparatus with a throttle assembly arranged for rotation by a user between a maximum forward position and a maximum backward position to modulate propulsion via a wheel drive system. The throttle assembly includes a handle configured to be gripped by the user and a throttle arranged for user-selected rotation relative to the handle about a central axis between a maximum forward throttle position and a maximum backward throttle position. A damper assembly is interposed between the throttle and the handle to provide torque resisting rotation of the throttle as the throttle rotates relative to the handle.

A patient support apparatus for transporting a patient over a floor surface is described herein. The patient support apparatus includes a drive system with a drive member, a user interface arranged for selective user engagement by a user to operate the drive system, and a control system for operating the drive system. The control system includes a processor configured to determine that the patient transport apparatus is traveling on an inclined floor surface, monitor the user interface for changes in user engagement by a user, and operate the drive system to decelerate the drive member to one of a plurality of positions based on the changes in user engagement.

Systems and methods for a load sensing system that determines a mass on a bed. The systems generally are in the form of a castor base, particularly one that can be used as part of an adjustable hospital bed. The load sensing system serves to determine the mass of any object or objects (typically a human or animal patient) which is placed on the bed by having the mass create a force on lever arms of a plurality of load cells in the castor base. The load sensing systems are designed to work without hindering the adjustable functionality of the bed and can accurately determine mass (weight) at any position of the bed, and potentially even while the bed is adjusting between positions.

A bed base frame assembly of a bed generally comprises a base frame, a plurality of steerable and lockable casters, a lateral support assembly at the first and second sides of the base frame assembly, and an in-line support assembly at the foot end of the base frame assembly. The lateral support assembly may further include: a base frame; a first leg and a second leg rotatably connected to the base frame; a first actuator connected to the first leg and the second leg, wherein the first leg and the second leg rotate from the retracted position to the extended position; a third leg and a fourth leg rotatably connected to the base frame; and a second actuator connected to the third leg and the fourth leg, wherein the third leg and the fourth leg rotate from the retracted position to the extended position.
