METHODS AND SYSTEMS FOR A DYNAMIC SUPPORT MATTRESS TO TREAT AND REDUCE THE INCIDENCE OF PRESSURE ULCERS
First Claim
1. A support including:
- a base structure formed from a single piece of a first material having a first density, the base structure extending a full length of the support and including a well with non-vertical, graduated sides;
a core layer formed from a single piece of second material having a second density, the core layer extending a full width of the base structure and having a non-rectangular trapezoidal prism shape that is wider at a top surface than at a bottom surface and is shaped to fit flush within the well in the base structure; and
a top layer formed from a third material having a third density, the top layer covering the core layer and at least a portion of the base structure,wherein the second density of the core layer is different than the first density of the base structure.

Abstract
Systems, methods, and apparatus are provided for preventing and treating pressure ulcers in bedfast patients. The invention includes providing a non-powered mattress having a first zone adapted to conform to a first body part and a second zone adapted to provide support to a second body part, and off-loading interface pressure on the first body part to the second body part by dynamically increasing the support provided to the second body part by the second zone based on a weight of the first body part on the first zone. The off-loading of interface pressure from the first body part to the second body part equalizes blood oxygen saturation in tissue of the first and second body parts. Numerous additional aspects are disclosed.

7. A mattress for preventing and treating pressure ulcers in bedfast patients, the mattress including:
-
a first zone adapted to support a scapular area of a patient; a second zone adjacent the first zone and adapted to support at least a sacrum area of the patient; and a third zone adjacent the second zone and adapted to support a leg area of the patient, wherein the second zone includes a structure adapted to compress the first and third zones based on weight applied to the second zone, and wherein compressing the first zone increases the support provided to the patient by the first zone and compressing the third zone increases the support provided to the patient by the third zone. - View Dependent Claims (8, 9, 10, 11, 12, 13)
