摘要： 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.

摘要： A system is provided that comprises a patient support apparatus and a unit being independent from the patient support apparatus. The patient support apparatus comprises a support structure having a base and a patient support surface for a patient. The patient support apparatus also comprises an electrical distribution system, one or more electrical devices, and an energy storage device (ESD) configured to store energy to power the one or more electrical devices through the electrical distribution system. The unit is configured to autonomously interact with the patient support apparatus to remove the ESD from the patient support apparatus and/or to place a replacement ESD on to the patient support apparatus.

摘要： 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.

摘要： A patient transport apparatus transports a patient over a floor surface. The patient transport apparatus comprises a support structure and support wheels coupled to the support structure. An auxiliary wheel is coupled to the support structure to influence motion of the patient transport apparatus over the floor surface to assist users. An actuator is operatively coupled to the auxiliary wheel and operable to move the auxiliary wheel relative to the support structure from a retracted position to a deployed position. A user interface sensor is operatively connected to the actuator and configured to generate signals responsive to the user touching the user interface. A controller is operatively coupled to the user interface sensor and the actuator to operate the actuator in response to detection of signals.

摘要： The present invention relates to controlling a removable electric propulsion system for a rolling object. In this method, a signal representative of the torque at a wheel driven by an electric machine of the electric propulsion system is measured (MES). This measurement is compared (COMP), over different time increments, with two thresholds, and the electric machine is controlled according to this comparison. The invention also relates to a propulsion system suited for this method and to a coupled assembly comprising the propulsion system and a rolling object.

摘要： Powered patient support apparatuses—such as beds, cots, stretchers, or the like—include a plurality of user controls that allow a caregiver to control the steering and/or driving of one or more powered wheels from multiple different locations around the patient support apparatus (e.g. head end, foot end, and/or the sides). The control is carried out by force sensors that detect both an orientation of the applied forces and a magnitude of the applied forces. Translational and/or rotational movement is effectuated, depending upon the magnitude and direction of the forces, as well as the physical location of the applied force relative to a reference point on the support apparatus, such as the center. One or more object sensors may also be included in the support apparatus to assist in steering and/or navigating.

摘要： A patient transport apparatus transports a patient over a surface. The patient transport apparatus comprises a base and support wheels coupled to the base. An auxiliary wheel assembly is coupled to the base and comprises one or more auxiliary wheels that influence motion of the patient transport apparatus over the surface to assist caregivers. An actuator system is operatively coupled to the auxiliary wheels to move the auxiliary wheels relative to the base from a stowed position to a first deployed position, and further to a second deployed position.

摘要： A patient support apparatus comprises a base supported by caster assemblies with each caster assembly comprising a stem, a caster wheel, and a caster wheel axle. A patient support surface is coupled to the base and is configured to receive a load. One or more load sensors are integrated with at least one of the stem, the caster wheel, or the caster wheel axle for measuring the load. One or more of the caster assemblies can be coupled to a steering motor, which controls orientation of the caster assembly. A controller can control the steering motors based on analyzing the measurements of the load sensor. The load sensors can produce measurements indicative of both vertical load and non-vertical load applied to the caster assembly. The controller can also analyze the measurements of the load sensor to determine the load received by the patient support surface by negating the non-vertical load.

摘要： A patient transport apparatus transports a patient over a surface. The patient transport apparatus comprises a support structure comprising a base, a patient support surface, and a reference sensor arranged to sense inclination of the support structure. A drive system is coupled to the support structure and operable to propel the patient transport apparatus. A handle assembly is operable by a user to control operation of the drive system. The handle assembly comprises a handle movable relative to the base and a position sensor arranged to sense positioning of the handle. A controller is coupled to the reference sensor and the position sensor, and is adapted to control the drive system in response to signals received from the reference sensor and the position sensor.
