Publication number: 20230329932Abstract: A patient transport apparatus with a base, a litter comprising a support surface, and a lift mechanism to facilitate arranging the litter at different heights relative to the base between a plurality of lift configurations including a fully-retracted configuration and a fully-extended configuration. The lift mechanism includes an actuator including a cylinder, fluid reservoir, and a pump driven by a motor to direct hydraulic fluid from the fluid reservoir to the cylinder. A sensor outputs a signal indicative of a magnitude of pressure in the cylinder. A user interface with an input control is provided. A controller determines a target parameter for the motor and, in response to user engagement with the input control, drives the motor at the target parameter to effect movement of the litter relative to the base at a predetermined rate irrespective of a weight of a patient supported on the litter.Type: ApplicationFiled: June 28, 2023Publication date: October 19, 2023Applicant: Stryker CorporationInventors: Joshua Alan Mansfield, Craig Lear, Ross Timothy Lucas

Patent number: 11771607Abstract: A patient support apparatus for supporting a patient comprising a support frame and a support deck coupled to the support frame. The support deck has a deck section arranged to articulate relative to said support frame between a first position and a second position. An actuator is interposed in force-translating relation between the support frame and the deck section to articulate the deck section. The actuator comprises a biasing device configured to store mechanical energy and having an interface. The actuator further comprises a torque multiplier coupled to the deck section and engaged with the interface to translate mechanical energy stored in the biasing device into force acting on the deck section to urge the deck section toward the first position.Type: GrantFiled: December 9, 2021Date of Patent: October 3, 2023Assignee: Stryker CorporationInventors: Shawn Trimble, Christopher S.

Patent number: 10987260Abstract: A patient handling apparatus includes a frame, a base, and a lift assembly supporting the frame relative to the base, the lift assembly configured to extend or contract to raise or lower the base or the frame with respect to the other of the base and the frame. The patient handling apparatus further includes a control system, which comprises at least one hydraulic cylinder to extend or contract the lift assembly, a hydraulic circuit to direct the flow of hydraulic fluid to and from the hydraulic cylinder, and a controller operable to control the hydraulic circuit. Based on an input signal, for example, an input signal that is indicative of a status or condition of the patient handling apparatus, the controller is configured to open, optionally automatically, fluid communication between the rod end chamber and the cap end chamber to redirect a portion of the fluid output from the rod end chamber to the cap end chamber when the rod is extending to thereby increase the extension speed of the rod.Type: GrantFiled: April 10, 2018Date of Patent: April 27, 2021Assignee: Stryker CorporationInventors: Chad Conway Souke, Ross Timothy Lucas
