Patent number: 10905520Abstract: An autonomous accessory support and system for transporting a medical accessory for delivering therapy that is coupled to a patient via a medical line. The autonomous accessory support comprises an accessory post for supporting the medical accessory. A movement module supports the accessory post for moving the accessory post relative to the patient. A tracking module is configured to track movement of the patient or a patient support apparatus relative to the autonomous accessory support and provide a tracking input signal. A controller is in electronic communication with the movement module and the tracking module. The controller controls the movement module to reduce actual patient proximity to a target patient proximity being a distance between the accessory support and the patient or the patient support apparatus sufficient to prevent tensioning of the medical line beyond a tension threshold. The distance may be a selectable preset distance maintained by the controller.Type: GrantFiled: November 10, 2017Date of Patent: February 2, 2021Assignee: Stryker CorporationInventors: Annie Désaulniers, William D. Childs, Michael Lau, Connor F. St. John, Krishna Bhimavarapu, Christopher R. Sweeney, Joshua E. Mix

Patent number: 10905606Abstract: A patient transport apparatus for moving a patient from one location to another. The patient transport apparatus comprises a suspension system to limit discomfort to the patient when the patient transport apparatus moves over disturbances in floor surfaces. The suspension system comprises suspension devices such as a spring and/or a damper. The suspension system is operable in an energy-absorbing mode in which the suspension system absorbs energy as wheels move over the disturbances during transport or a lockout mode in which the suspension system is relatively more rigid as compared to the energy-absorbing mode. A control system operates to place the suspension system in one of the modes.Type: GrantFiled: February 26, 2020Date of Patent: February 2, 2021Assignee: Stryker CorporationInventors: Jerald A. Trepanier, Kevin M. Patmore, Anish Paul, William D. Childs

Publication number: 20200261287Abstract: A patient transport apparatus for transporting a patient over a surface. The patient transport apparatus has support wheels coupled to a base and swivelable about swivel axes. An auxiliary wheel assembly is coupled to the base and includes an auxiliary wheel configured to move between a plurality of wheel positions, and an actuator operably coupled to the auxiliary wheel to move the auxiliary wheel between the plurality of wheel positions. A sensing system with a sensor is provided to detect a motion condition of the patient transport apparatus. A controller is coupled to the sensing system and to the actuator, and is configured to drive the actuator to move the auxiliary wheel between the plurality of wheel positions based on the motion condition of the patient transport apparatus.Type: ApplicationFiled: May 8, 2020Publication date: August 20, 2020Applicant: Stryker CorporationInventors: William D. Childs, Kevin M. Patmore, Brian Tessmer, Marco Constant

Publication number: 20200237595Abstract: A patient support apparatus comprising a base, an intermediate frame arranged for movement relative to the base, a support deck disposed on the intermediate frame to provide support for a patient, and a telescoping assembly operatively attached to the intermediate frame. The telescoping assembly comprises a support movable between a collapsed position and an extended position, a lock operable to releasably hold the support in the extended position, and an accessory manually movable by a user relative to the support between a stowed position and a use position. The accessory comprises a deactivator operable to deactivate the lock remotely from the user in response to the user manually moving the accessory relative to the support toward the stowed position thereby enabling movement of the support from the extended position to the collapsed position.Type: ApplicationFiled: April 16, 2020Publication date: July 30, 2020Applicant: Stryker CorporationInventors: Michael William Graves, Richard A.

Patent number: 10682269Abstract: 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 to influence motion of the patient transport apparatus over the surface to assist caregivers. The auxiliary wheel assembly comprises auxiliary wheels and an actuator operably coupled to the auxiliary wheels. A controller adjusts the actuator based on input from a sensing system so that frictional forces acting between the auxiliary wheels and the surface are sufficient for steering and maneuvering of the patient transport apparatus, without sacrificing stability of the patient transport apparatus.Type: GrantFiled: June 13, 2018Date of Patent: June 16, 2020Assignee: Stryker CorporationInventors: William D.
