Abstract: Described are computer-based surgical methods and apparatuses for a self-detecting kinematic assembly. The self-detecting kinematic clamp assembly detects and indicates a degradation in pose. The self-detecting kinematic clamp assembly includes a tracking element for tracking a pose of the kinematic clamp assembly. The self-detecting kinematic clamp assembly includes a base portion comprising a fixation device that is attachable to a rigid body, and a top portion connected to the tracking element, the top portion being removably connected to the base portion. The self-detecting kinematic clamp assembly includes a detection mechanism, the detection mechanism including three or more contact points between the base potion and top portion and a mechanism that detects movement between one or more of the three or more contact points.

Abstract: A mattress for a bed is provided to support a patient. The mattress includes a plurality of air fluidized bladders. Each bladder includes a fluidized zone having fluidizable material positioned therein. Each bladder further includes a diffuser configured to provide air to the fluidized zone to fluidize the material.

Abstract: A patient support is provided having a frame, a deck positioned on the frame, and a mattress. The patient support further including a siderail configured to move relative to the frame.

Abstract: A patient support is provided having a frame, a deck positioned on the frame, and a mattress. The deck includes a deck section configured to move relative to the frame. The frame includes a recessed portion configured to receive the deck section during movement of the deck section relative to the frame.

Abstract: A mattress for a bed is provided to support a patient. The mattress includes a plurality of air fluidized bladders. Each bladder includes a fluidized zone having fluidizable material positioned therein. Each bladder further includes a diffuser configured to provide air to the fluidized zone to fluidize the material.

Abstract: A mattress assembly including an inflatable central support portion and a side bolster. A check valve is configured to prevent fluid flow from at least a portion of the side bolster to the central support portion.

Abstract: A mattress assembly comprises an inflatable central support portion having a head end, a foot end, a first side and a second side, and first and second side bolsters coupled to the first and second sides, respectively, of the inflatable central support portion. The first and second side bolsters each have at least two chambers extending along a longitudinal axis of the first and second side bolsters. At least one of the chambers is a manifold in fluid communication with the central support portion. The manifold is configured to be coupled to an air supply to supply air to the central support portion and the other chambers.

Abstract: A mattress is provided having an elongated foam base, a plurality of air sacks positioned above the foam base, and a longitudinally-extending manifold. Each air sack defines an interior region. The manifold includes an outer wall defining an interior region in fluid communication with a source of pressurized fluid and in fluid communication with the interior region of each air sack. The foam base and the plurality of air sacks cooperate to define a channel. The manifold is positioned in the channel and supported on top of the foam base.

Abstract: An apparatus is provided to support a mattress. The apparatus includes a base platform that is formed to rest on a box spring and to include slots therethrough, a plate hinged to the base platform, and a bladder fastened between the plate and the base platform. In addition, the apparatus includes a fastener mechanism coupled to the plate and adapted to block sliding movement of the mattress relative to the plate and a strap coupled to the base platform. The strap extends through the slots and is configured to extend about the box spring to hold the base platform on the box spring.

Abstract: An apparatus is configured for mounting a blower motor into a blower housing. The blower housing has an interior region for receiving the blower motor. The apparatus comprises a top shell configured to surround a top portion of the blower motor and a bottom shell configured to surround a bottom portion of the blower motor. The top and bottom shells are configured to hold the blower motor in the interior region of the housing without a rigid connection between the blower motor and the blower housing. The top shell cooperates with the bottom shell to define an air intake manifold to provide flow of intake air to the blower motor.

Abstract: An apparatus for controlling the pressure of fluid within a chamber upon which a person rests includes a manifold having a wall defining an interior region in fluid communication with a source of pressurized fluid and an air sack defining the chamber. The air sack includes a wall defining an interior region of the air sack. The wall is formed to include an air loss opening in fluid communication with the interior region of the air sack. The apparatus also includes a flow control assembly having a conduit in fluid communication with the interior region of the air sack and with the interior region of the manifold. The flow control assembly also includes a check valve mounted in the conduit to prevent the flow of pressurized fluid through the conduit from the interior region of the air sack to the interior region of the manifold.
