A recently granted patent (Publication Number: US11969100B2) discloses a method for providing a support surface for a patient. The method involves forming a foam frame defining a space, positioning a bladder assembly within the space, and enclosing both components in a cover. The cover is designed to engage an articulated frame to control movement in response to the frame's motion. Protrusions are secured to the foam frame and bladder assembly, which can be received in receivers on the articulated frame of a patient support apparatus to secure the components in place.

Furthermore, the method includes additional steps such as securing the bladder assembly to the cover at a second location, forming the cover with pockets to secure the bladder assembly, and incorporating a plate that floats within the bladder assembly to enhance support. The bladder assembly is made up of foam-filled bladders interconnected in a manifold, with features like unpowered relief valves and check valves to regulate air pressure. Different groups of foam-filled bladders can offer varying levels of support for different parts of the patient's body, enhancing comfort and customization. Additionally, the bladders are designed with transparent windows for color-coding to help users identify and associate specific performance characteristics with each bladder. The cover also includes pockets to secure the bladder assembly at a second location, ensuring stability and support for the patient.
