20080271245 | Inflatable mattress with uniform restraint - A cushioning device having a first deep cell inflatable bladder, a first restraint structure, a pump and an attachment. The first deep cell inflatable bladder has a first side, a second side, an upper surface and a lower surface. The first restraint structure has a top surface and a bottom surface. The pump has (a) a maximum inflation mode that inflates the first deep cell inflatable bladder so the bladder's upper surface and the first restraint's top surface are in or approximately in the same plane and (b) a normal operating inflation mode that provides sufficient inflation to (A) prevent the first bladder's upper surface from contacting the first bladder's lower surface, (B) decrease (i) the formation of debuticus ulcers on a patient and (ii) the patient's tissue interface pressure, and (C) allow the restraint structure to inhibit and/or restrain the patient from rolling off the first deep cell inflatable bladder. The attachment attaches at least a portion of the first bladder's first side to the first restraint structure at a predetermined distance below the first restraint's top surface so (A) the first restraint during the normal operating mode inhibits and/or restrains the patient from rolling off the first deep cell inflatable bladder, and (B) the first restraint and first deep cell inflatable bladder provide lateral stability to allow the patient to get in and out of the cushioning device and facilitating patient transfers during the maximum inflate mode. | 11-06-2008 |
20090106898 | ADAPTABLE MATTRESS CONVERSION - A mattress system has a cover, a crib, and a fluid bladder system. The crib surrounds the perimeter of the fluid bladder system and the cover overlies the top surface of the crib and fluid bladder system. The fluid bladder systems provide at least one conventional bladder therapy to a patient positioned on the mattress system. The fluid bladder system interconnects to the crib to not form a hammock effect so the crib functions as a restraint. The fluid bladder is also designed to bottom out to form an exterior cavity. A second cushion is inserted into the exterior cavity and positioned so the crib continues to function as a restraint. The second cushion provides a therapy to the patient that is different from the fluid bladder system. | 04-30-2009 |
20100199437 | MULTI-WALLED GELASTIC MATERIAL - The present invention is directed to a gelastic cushion. The gelastic cushion is made from a conventional gelastic composition. The gelastic cushion has a structure having a first wall that defines an opening area and buckles when a force is applied to the first wall. When the first wall buckles a predetermined amount, a second wall, interconnected to the first wall, also buckles. The second wall decreases the chance that the first wall bottoms out. Bottoming out increases the pressure on the patient (a.k.a., the force) overlying the gelastic cushion. That increased pressure is undesirable. | 08-12-2010 |

20110030144 | CUSHION BLADDER WITH MIDDLE LAYER HAVING GAPS AND VARIOUS POSITIONED INTERIOR WELDS - A cushioning device has a first material and an opposing second material that are sealed together at the peripheral edges to form a first (right) side, a first (head) end, a second (left) side, and a second (foot) end. Positioned between the first material and the second material is a middle material. The middle material has a top side, a bottom side, a first gap between the first side and the middle material and a second gap between the second side and the middle material. In addition, the first material is sealed to the middle material's top side at a first set of locations to form a first set of interior welds. The second surface is sealed to the middle material's bottom surface at a second set of locations to form a second set of interior welds. The first set of interior welds on the middle material's top surface and the second set of interior welds on the middle material's bottom surface are not superimposed on each other or overlap each other. | 02-10-2011 |
20120060295 | DECREASED SHEAR GELATINOUS CUSHION - A gelatinous elastomeric cushion having decreased shear forces applied to the patient by altering the gelatinous elastomeric configuration in certain areas. For example, the decreased gelatinous elastomeric material does not have secondary walls align with each other. Alternatively, the cushion has different gelatinous configurations in different sections of the cushion to intentionally elongate the walls to decrease the shear pressure applied to the patient. | 03-15-2012 |
20130205507 | CUSHION BLADDER WITH MIDDLE LAYER HAVING GAPS AND VARIOUS POSITIONED INTERIOR WELDS - A cushioning device has two materials that are sealed together at their peripheral edges to form first and second sides and first and second ends. Positioned between the first and second materials is a middle material. The middle material has the top and bottom sides, a gap between the first side and the middle material and another gap between the second side and the middle material. In addition, the first material is sealed to the middle material's top side by a first set of interior welds. The second surface is sealed to the middle material's bottom surface by a second set of interior welds. The first set of welds on the middle material's top surface and the second set of welds on the middle material's bottom surface are not superimposed on each other or overlap each other. | 08-15-2013 |
