Abstract: A pressure sore prevention mattress is provided alternating pressure points on the body of an occupant that is easily transformable between two stable configurations. The four-layer mattress construction has a top foam pad, a webbing layer, a dynamic layer of deformable panels trapezoid-shaped four-bar mechanisms that deform to produce an undulating pattern of peaks, and a base. Panel geometry can determine peak height. The mattress has a spatially hollow geometry that allows natural air convection through the breathable top foam pad to enable drying of moisture as well as the use of forced air convective drying or cooling. The mattress can be transformed from one configuration to the other while the occupant is on the mattress.

Abstract: A collection bin locking assembly with a gravity-actuated release mechanism is disclosed herein. The locking assembly includes a housing attached to the body of the bin and a separate cord support structure attached to the lid. When locked, a cord spans between a first cord support structure on the housing and the separate or second cord support structure on the lid. A pendulum is disposed within the housing which, due to gravity, automatically swings between a first, resting position and a second, unlocked positioned when the collection bin is moved from an upright position to an at least partially upended position. Furthermore, the first cord support structure includes a groove and, adjacent to the groove, a smooth, outwardly curved surface. When the pendulum swings, the cord is forced out of the groove and onto the adjacent smooth, outwardly curved surface where the cord will slip off, thereby unlocking the lid.

Abstract: A system for preventing and treating pressure sores of a bed-ridden patient including an array of expandable and collapsible supports to support and provide pressure relief to a patient in pressure locations where the expandable and collapsible supports support the patient; pressure sensors associated with the expandable and collapsible supports to monitor pressure locations where the expandable and collapsible supports support the patient; and a patient lift movable between the expandable and collapsible supports to raise and lower the patient between at least a position where the patient is primarily supported by the array of expandable and collapsible supports and a position above the expandable and collapsible supports where the patient is primarily supported by the patient lift.

Abstract: The subject invention pertains to novel materials and methods for use in delivering and sequestering substances, such as pharmacological agents, within a patient. One aspect of the invention is directed towards core-shell particles having a core encapsulated within a calcium carbonate shell, with an intermediate layer composed of an amphiphilic compound surrounding the core. When the particles of the subject invention are administered to a patient, they are capable of removing lipophilic drugs by absorption of the drug through their mineral shell and into their core. The particles of the subject invention can also be administered to a patient as controlled release, drug delivery vehicles. Thus, in another aspect, the subject invention concerns a method of delivering pharmacological agents by administering the core-shell particles of the subject invention to a patient in need of such administration.

Abstract: A system such as a hospital bed provides capability to monitor and alleviate the pressure points and provides oxygen and water jets to prevent and treat bed sores in bed-ridden patients. An array of balloons touching each other form a mattress of unstitched but contiguous balloons like in a conventional mattress with stitched puffs. Individual pressure sensors placed within each balloon measure and monitor pressure. Furthermore, horizontal rods which lay between the balloons perform oxygenation and provide water massage to the back of the patient body from the interstitial spaces within the unstitched mattress of contiguous balloons. The rods are elevated to raise the patient above the mattress to relieve overall pressure and enable cleaning and wipe down of the back of the patient body. The rods can elevate the entire patient body or its torso alone or the lower extremities alone to clean as desired.
