Mattress Cover For A Mattress Providing Rotation Therapy To A Patient

A mattress cover for coupling to a mattress having an upper surface opposite a lower surface and a thickness defined between the upper surface and the lower surface with the mattress providing movement therapy comprising increasing the thickness of the mattress with a patient disposed thereon, the mattress cover comprising:

• a patient support portion adapted to cover the upper surface of the mattress, the patient support portion having an outer periphery sized so that a majority of the patient is supported on the patient support portion within the outer periphery during the movement therapy;
• and
• a bottom portion opposite the patient support portion and adapted to cover the lower surface of the mattress such that the mattress is disposed between the patient support portion and the bottom portion;
• and
• an augmenting feature associated with one of the peripheral portions and being adapted to move between a stored configuration in the absence of the movement therapy, and a deployed configuration in response to increasing the thickness of the mattress during the movement therapy, the augmenting feature including a resilient member adapted to bias the augmenting feature toward the stored configuration,
• wherein the patient support portion is adapted to at least partially overlap the bottom portion and move relative to the bottom portion to accommodate increasing thickness of the mattress during the movement therapy such that the overlap decreases with the increasing thickness of the mattress.

A movement therapy mattress assembly comprising:

• a mattress having an upper surface, a lower surface, sides, and a patient turning device positioned adjacent to the lower surface and adapted to move the mattress to provide movement therapy;
• and
• a mattress cover comprising:
• a patient support portion covering the upper surface of the mattress, the patient support portion having an outer periphery sized so that a majority of the patient is supported on the patient support portion within the outer periphery during the movement therapy;
• a bottom portion coupled to the patient support portion, the bottom portion covering the patient turning device;
• and
• peripheral portions extending between the patient support portion and the bottom portion, the peripheral portions covering the sides of the mattress;
• and
• an augmenting feature associated with the mattress cover and adapted to move between a stored configuration in the absence of the movement therapy and a deployed configuration to accommodate movement of the mattress during the movement therapy, the augmenting feature including a roller configured to pivot about an axis with one of the peripheral portions at least partially furled about the roller.
