A rollator having a first side frame and a second side frame; the first side frame comprising a first side frame intervening structural portion; the second rolling side frame comprising a second side frame intervening structural portion; a central platform having a first platform side and a second platform side; and first and second track mechanisms respectively coupling the first and second side portions to the first and second platform sides of the central platform; the first and second track mechanisms permitting independent movement of said first and second side frames relative to said central platform.

A process (and apparatus) of managing pressure injuries provides a two-dimensional array of expandable, compressible cells. Each cell has a contact surface with an associated contact pressure, and the array of cells includes a given cell with a given contact surface and at least one cell adjacent to the given cell (“adjacent cell”). A controller expands the array of cells. The process also monitors the contact pressure of a body on the contact surface and detects a given contact pressure exceeding or equal to a predetermined threshold contact pressure. The controller may produce a pressure reduction response when determining that the given contact pressure exceeds or equals the predetermined threshold contact pressure. This automatically causes the controller to modify the internal air pressure of the given cell and the internal air pressure of the adjacent cell.

A seating system, particularly suited for personal mobility vehicles, such as wheelchairs, includes a seat cushion having pressure relieving properties and enhanced thermal conduction properties. The seat cushion includes a thixotropic fluid contained within a flexible envelope. The thixotropic fluid includes nanoparticles that enhance the thermal conduction properties of the seat cushion to increase heat transfer from a seated user to provide a reduced temperature sensory effect.

A chair support and booster seat is shown and described. The chair support and booster seat is comprised of a frame. The frame is comprised of a lower frame section rotatably coupled to an upper frame section. The upper frame section is comprised of a pair of vertical supports. A securement arm is rotatably coupled to each one of the pair of vertical supports. A chair seat is secured to the lower frame section.

A patient examination system including a frame assembly, one or more motion-controlling assemblies connected to the frame assembly for moving one or more selected movable portions of the frame assembly, and a patient support assembly. The patient support assembly includes a seat subassembly including a seat cushion, a back subassembly, a footrest subassembly including a footrest cushion, and a cover element covering a top side of the seat cushion and an external side of the footrest cushion. The cover element has an exposed surface for engagement with the patient. The seat subassembly includes the seat cushion and is secured to the upper element of the frame assembly. The frame assembly is configured to support the seat subassembly relative to the floor in a lowered position thereof, in a raised position thereof, in intermediate seat positions therebetween, and in Trendelenburg positions.

A method for fabricating a custom anatomical cushion and a device to capture pressure controlled shape is provided. The device comprises, generally, a flexible membrane enclosing floating beads adapted to be completely immersed and freely moving inside a fluid. The device further comprises a mesh adapted to stop the floating beads from going outside of the flexible membrane as a result of a pressure increase or decrease inside the flexible membrane. The device is being fluidly connected to a pressure control system adapted to increase and/or decrease the internal pressure of the flexible membrane and comprises a vibration/leveling system adapted to adjust the fluid level inside the flexible membrane.

An apparatus is disclosed for adjusting an active length of a plurality of interwoven support elements of a weight bearing surface to conform to contours of a user's anatomy. The weight bearing surface overlies a frame to which the plurality of interwoven support elements are connected. The apparatus includes an adjustment mechanism connected to one of the plurality of interwoven support elements, wherein the adjustment mechanism is attached or releasably attached to the frame. The adjustment mechanism allows the active length of the connected interwoven support element to change as a user bears upon the weight bearing surface, thereby conforming the weight bearing surface to the contours of a user's anatomy. In another aspect, a method for adjusting an active length of at least some of a plurality of interwoven support elements of a weight bearing surface to conform to contours of a user's anatomy is disclosed.

An adjustable chair assembly comprising a frame, a seat assembly, a back assembly and at least one of a seat space-filling element and a back space-filling element. The seat assembly extends along a seat plane and comprises a first seat element and a second seat element adjustably positionable with respect to one another along the seat plane and together defining a support surface of the seat assembly. The back assembly extends along a back plane and comprises a first back element and a second back element adjustably positionable with respect to one another along the back plane and together defining a support surface of the back assembly. A central gap is defined in at least one of the support surfaces and the at least one of the seat space-filling element and the back space-filling element is removably insertable in the central gap of the corresponding support surface.

Apparatuses including features for predicting pressure wound formation are disclosed. A wheelchair apparatus includes a seat having a surface that contacts a subject when the subject is sitting in the wheelchair apparatus. The surface includes a thermochromic layer having one or more materials that cause the thermochromic layer to change to a first color upon application of thermal energy radiating from the subject that corresponds to a baseline body temperature and change to a second color that is different from the first color upon application of thermal energy radiating from the subject that corresponds to a temperature that exceeds a threshold difference from the baseline body temperature. The second color is indicative of a potential pressure wound.

A backrest having features that support proper sitting posture of a user to improve back health and posture may be utilized. The backrest may include a front wall with wings extending to the left and right and diagonally forward to reduce Kyphosis of a user when sitting against the backrest. A combination of the front wall and wings may causing the user's (i) back ribs to be raised and gently tilted forward and (ii) thoracic spine region to be gently thrusted forward. By thrusting the thoracic spine region and raising and tilting the back ribs, a user's abdominal cavity may be expanded, and thereby reinforcing the ideal positioning of the cervical spine so that the user's head naturally positions on axis and does not “dump” forward.
