Abstract
A patient support is provided. The patient support may include a plurality of inflatable members that raise or lower portions of the patient support based on the status of a valve assembly. The patient support may also include a plurality of inflatable members positioned at a foot end of the patient support to support lower legs of a patient including their heels. Another valve assembly is provided to control a bleed rate of air from the heal bladders.
Claims12
A patient support, comprising:
- a right side bladder having an interior region;
- a left side bladder having an interior region;
- a valve assembly in fluid communication with the interior regions of the right and left side bladders, the valve assembly having a body and a first rotatable member, the first rotatable member being positionable relative to the body in a plurality of positions to control the inflation and deflation of the right and left bladders, wherein the first rotatable member is positionable in at least one position resulting in either a simultaneous inflation of both the right and left bladders or a simultaneous deflation of both the right and left bladders;
- wherein the plurality of positions includes a first position resulting in one of the right side bladder and the left side bladder being inflated, a second position resulting in the other of the right side bladder and the left side bladder being inflated, a third position resulting in the left and right side bladders being simultaneously inflated, and a fourth position resulting in the right side and left side bladders being simultaneously deflated;
- and
- a right foot bladder positioned to support a right lower leg of a patient, and a left foot bladder positioned to support a left lower leg of a patient, wherein the right side bladder is positioned to support a right side of a patient torso and the left side bladder is positioned to support a left side of the patient torso, and the plurality of positions includes a fifth position resulting in the right and left side bladders and the right and left foot bladders being inflated, the valve assembly deflating the right and left foot bladders when in the fourth position.

A patient support configured to be used as a bed, the patient support comprising:
- a plurality of bladders positioned to support a lower leg of a patient, each of the bladders including an interior region, and
- a valve assembly in fluid communication with the interior region of at least one of the plurality of bladders, the valve assembly having a plurality of positions to control at least two distinct stepped bleed rates of pressurized fluid from the interior region of the at least one bladder using a plurality of apertures having different sizes to variably control the at least two distinct stepped bleed rates.
