Patent ID: 8296887

Claim:
A therapeutic support comprising a rotational (turn-assist) bladder system and a control unit; the rotational (turn-assist) bladder system has a right side bladder component and a left side bladder component positioned on a support surface; the right side bladder component has (I) a first right section with a first right resilient structure (a) positioned on the first right section's bottom surface and (b) has a height that (i) allows the fluid in the first right section to be the primary patient support in the first right section wherein the right side bladder contacts the patient directly or through a non-supporting layer, and (ii) inhibits a patient from bottoming out only when the patient's weight displaces the first right section's fluid from being positioned between the patient and the support surface; and (II) a second right section with a second right resilient structure (a) positioned on the second right section's bottom surface and (b) has a height that (i) allows the fluid in the second right section to be the primary patient support in the second right section wherein the right side bladder contacts the patient directly or through a non-supporting layer and (ii) inhibits a patient from bottoming out only when the patient's weight displaces the second right section's fluid from being positioned between the patient and the support surface: and the left side bladder component has (I) a first left section with a first left resilient structure (a) positioned on the first left section's bottom surface and (b) has a height that (i) allows the fluid in the first left section to be the primary patient support in the first left section wherein the left side bladder contacts the patient directly or through a non-supporting layer, and (ii) inhibits a patient from bottoming out only when the patient's weight displaces the first left section's fluid from being positioned between the patient and the support surface; and (II) a second left section with a second left foam section (a) positioned on the second left section's bottom surface and (b) has a height that (i) allows the fluid in the second left section to be the primary patient support in the second left section wherein the left side bladder contacts the patient directly or through a non-supporting layer, and (ii) inhibits a patient from bottoming out only when the patient's weight displaces the second left section's fluid from being positioned between the patient and the support surface.
