A bed structure includes a bedstead formed by bedstead units. The bedstead units are symmetrically arranged with respect to the central axis of the bedstead. The bedstead unit includes a first bedstead unit and a second bedstead unit. The first bedstead unit is hinged to the second bedstead unit. A motor is provided between the first bedstead unit and the second bedstead unit. The bedstead units at both sides of the central axis of the bedstead are hinged by a fixing rod. Each of two ends of the fixing rod is provided with a clamping member. The bedstead unit is provided with a matching member connected to the clamping member. The clamping member and the matching member are hinged by a fastener. In this arrangement, the electric bed can be folded.

Disclosed are a driving assembly, a folding bed and a folding bed frame using the driving assembly. The driving assembly includes a first driving cylinder and a first force transmission assembly, one end of the first driving cylinder is fixedly mounted with a first connecting seat, the other end is rotatably connected to a second connecting seat; the first force transmission assembly includes a third connecting seat fixedly connected to the first base, a first force transmission rod rotatably connected to the third connecting seat, and a second force transmission rod rotatably connected to the first force transmission rod, the first force transmission rod is fixedly connected to the second connecting seat, and the second force transmission rod is configured to be rotatably connected to the back support.

A foldable bed includes a bed frame structure having a back frame and a leg frame connecting to the back frame such that the back frame and the leg frame are pivotally foldable relative to one another along a length direction of the foldable bed; and a plurality of boards detachably attached onto the bed frame structure along the length direction of the foldable bed, wherein each board comprises a pair of panels arranged along a width direction of the foldable bed.

A mattress assembly includes a chassis having top and bottom walls and first and second sidewalls that each extend from the top wall to the bottom wall. Inner surfaces of the walls and the sidewalls define an interior cavity. The top and bottom walls each include a first section that is connected to the first sidewall and a second section that is connected to the second sidewall such that the first sections are pivotable relative to the first sidewall and the second sections are pivotable relative to the second sidewall. The first section of the top wall is pivotable relative to the second section of the top wall and the first section of the bottom wall is pivotable relative to the second section of the bottom wall. A spring assembly is configured to be positioned within the interior cavity.

A bed assembly includes a pair of expandable structural frame members, each having a compact position with a first frame length and an expanded position with a second frame length longer than the first frame length, a plurality of cross frame members each having a pair of opposing ends and each opposing end releasably attachable to one of the expandable structural frame members in the expanded position and a plurality of decking panels each releasably attachable to the pair of expandable structural frame members in the expanded position.

Embolic protection elements are integrated with a catheter or access sheath for any catheter. A catheter with an integrated embolic protection element comprises a catheter shaft, an embolic filter slidably mounted on a distal portion of the shaft, a proximal stop for limiting the proximal movement of the embolic filter, and a distal stop for limiting the distal movement of the embolic filter. The filter comprises a porous mesh material defining a collection chamber for captured emboli and has a collapsed and a deployed configuration. The filter may be collapsed by an access sheath used with the catheter. An access sheath may comprise a tubular main body and an embolic filter mounted on the distal portion of the tubular main body. The embolic filter may evert into the central lumen of the sheath or may be constrained on the exterior of the sheath with a larger diameter outer tube.

Disclosed are collapsible beds and bed frames. A collapsible bed frame includes first and frame units disposed side by side and connected with each other at their proximal sides. Each of the first and second frame units comprises a plurality of bar units. Adjacent bar units are connected with each other and rotatable with respect to each other along one or more axes each substantially perpendicular to a first plane defined by a top surface of the collapsible bed frame when it is expanded. The first and second frame units can contract and expand while remaining on the first plane and while connected with each other.

A flexible article is provided having a core formed from a plurality of laminar panels that are inter-connected to provide an expandable structure upon movement of the panels away from each other. Opposite ends of the core terminate in a pair of end panels whereby the end panels may be moved apart to expand the expandable structure. Each of the panels are made from wood material. The panels, for example, include two wood sheets with longitudinally oriented grains and a flexible backing sheet that is sandwiched and adhered between the two wood sheets.

An adjustable bed system includes first and second frames; a back lifting assembly having a back lifting bracket pivotally connected to the first frame and a back lifting actuator pivotally connected between the back lifting bracket and the first frame for operably driving the back lifting bracket to pivotally move in an upward or downward rotating direction relative to the first frame; a leg lifting assembly having a leg lifting bracket pivotally connected to the second frame structure and a leg lifting actuator pivotally connected between the leg lifting bracket and the second frame for operably driving the leg lifting bracket to pivotally move in an upward or downward rotating direction relative to the second frame; and a foldable connection mechanism connecting the first and second frames such that the first and second frames are pivotally foldable relative to one another at the connection mechanism.
