Patent number: 12263126Abstract: A protective system for a patient transport apparatus includes the patient transport apparatus with a base arranged for movement along floor surfaces and an intermediate frame coupled to the base and supporting a patient support deck. A mattress is disposed on the patient support deck. The protective system further includes a keeper coupled to the intermediate frame and further includes a cover having a first side configured to absorb fluid and a second side configured to at least partially limit fluid from transferring through the cover towards the first side. The cover is movable by a caregiver between three positions: (i) a stowed position secured within the keeper, (ii) an environmental deployed position with the first side facing towards the mattress, and (iii) a patient deployed position with the first side facing away from the mattress.Type: GrantFiled: March 28, 2023Date of Patent: April 1, 2025Assignee: Stryker CorporationInventors: Mackenzie Van Loon, Hieu Phan, James K. Galer

Patent number: 11986429Abstract: A patient transport apparatus is provided with a lift mechanism to move a litter relative to a base between lift configurations, a user interface with an input control and an indicator, a height sensor, and a controller. The controller is configured to compare signals generated by the height sensor against a value associated with a transport configuration, operate the indicator in a first state when the signal corresponds to the value to communicate to a user that the litter is arranged in the transport configuration, to operate the indicator in a second state when the signal differs from the value to communicate to the user that the litter is arranged in a lift configuration other than the transport configuration, and to drive the lift mechanism to move to the transport configuration in response to the signal being within a predetermined threshold of value upon user disengagement of the input control.Type: GrantFiled: May 13, 2021Date of Patent: May 21, 2024Assignee: Stryker CorporationInventors: William Ross Heneveld, Jr., Hieu Phan

Patent number: 11801161Abstract: A reinforcing clinical wrap is provided with integral thermal management. The clinical wrap includes a fluid circuit for a heat transfer medium to circulate between a fluid inlet and a fluid outlet. A shape conforming medium is disposed within a portion of the clinical wrap providing selective reinforcement support of the portion of the clinical wrap to conform to a surface of a patient. Non-limiting examples of the shape conforming medium may include a magnetorheological elastomer, a magnetorheological elastomer, a magnetorheological foam, a UV curable resin, and a phase change material.Type: GrantFiled: September 26, 2022Date of Patent: October 31, 2023Assignee: Stryker CorporationInventors: Gregg Taylor, Alexey Titov, Hieu Phan
