Publication number: 20240024183Abstract: A patient transport apparatus for transporting a patient over a floor surface is described herein. The patient transport apparatus includes an auxiliary wheel assembly including an auxiliary wheel, an auxiliary wheel drive system, and a control system for operating the auxiliary wheel drive system based on user commands. The control system includes a processor that is programmed to receive a user command to operate the auxiliary wheel drive system in a drive mode and responsively operate a motor control circuit to transmit power signals to a motor to rotate the auxiliary wheel. The processor is also programmed to receive a user command to operate the auxiliary wheel drive system in a free wheel mode and responsively operate the motor control circuit to enable the auxiliary wheel to rotate relatively freely with the auxiliary wheel in a deployed position.Type: ApplicationFiled: September 28, 2023Publication date: January 25, 2024Applicant: Stryker CorporationInventors: Richard A. Derenne, Gary L. Bartley, Scott A. Kuebler, Tyler Ethen, Matthew Aaron Whitehead, Anish Paul

Publication number: 20230038537Abstract: A patient transport apparatus includes a base, a patient support deck, a plurality of wheels, a plurality of brakes, and an electro-mechanical braking system. The electro-mechanical braking system includes a linkage, a manual actuator, and an electrical braking assembly. The linkage is operatively coupled to the brakes to place the brakes in a braked state, a released state, or other state. The manual actuator moves the linkage manually to place the brakes in one of the states. The electrical braking assembly includes an actuator assembly that moves the linkage with electrical power to place the brakes in one of the states.Type: ApplicationFiled: December 23, 2020Publication date: February 9, 2023Applicant: Stryker CorporationInventors: Charles Donald Baker, JR., Krishna Sandeep Bhimavarapu, William Dwight Childs, Tyler Ethen, Kirby M. Neihouser, Anish Paul, Lavanya Vytla

Publication number: 20210196533Abstract: A patient transport apparatus for transporting a patient over a floor surface is described herein. The patient transport apparatus includes a throttle assembly, an auxiliary wheel assembly including an auxiliary wheel, an auxiliary wheel drive system, and a control system for operating the auxiliary wheel drive system based on user commands received from the throttle assembly. The control system includes a controller configured to detect a position of the throttle assembly, determine a desired rotational speed value associated with a current operating throttle position, determine a current rotational speed of the auxiliary wheel, select an acceleration rate based on the current rotational speed of the auxiliary wheel, generate an output signal based on the selected acceleration rate, and transmit the generated output signal to the motor control circuit to operate the motor to rotate the auxiliary wheel at the selected acceleration rate.Type: ApplicationFiled: December 23, 2020Publication date: July 1, 2021Applicant: Stryker CorporationInventors: Richard A.

Publication number: 20200405555Abstract: A patient transport apparatus comprises a base, a patient support deck, a wheel assembly, and a braking system. The wheel assembly includes a wheel and a braking mechanism. The braking system includes a linkage assembly, a manual actuator, and an electrical braking assembly. The linkage assembly is arranged to place the braking mechanism in a braked state and a released state. The manual actuator moves the linkage assembly manually to place the braking mechanism in the braked state and the released state. The electrical braking assembly includes a driving assembly that moves to a first position and to a second positing that causes the linkage assembly to place the braking mechanism in the braked state and the released state. The linkage assembly is movable relative to the driving assembly to enable the braking mechanism to be manually actuated with the manual actuator.Type: ApplicationFiled: September 16, 2020Publication date: December 31, 2020Applicant: Stryker CorporationInventors: Joseph Adam Upchurch, Tyler Ethen, Gary L.
