    摘要: A polyurethane dispersion and a method of making are provided. The polyurethane dispersion is stable in a mixture of alcohol and water. The dispersion comprises the reaction product of (a) an isocyanate terminated polyurethane prepolymer comprising the reaction product of (i) at least one oligomeric polyactive hydrogen compound insoluble in said alcohol, wherein said polyactive hydrogen compound is an alkyl, aryl, or aralkyl structure optionally substituted by N, O, and S; (ii) at least one polyisocyanate, and (iii) at least one polyactive hydrogen compound soluble in said mixture of alcohol and water; (b) a polyfunctional chain extender; and (c) a monofunctional chain terminator; wherein the equivalent ratio of difunctional chain extender to prepolymer isocyanate is 0.60 to 1.20.

    摘要: Patient support systems and methods for transferring patients and controlling patient temperature. The system can include a non-inflatable and self-supporting platform that can include a first surface and a second surface separated by a distance, a plurality of supporting structures that extends at least partially across the distance between the first surface and the second surface, a plenum, and a plurality of apertures formed through at least one of the first surface and the second surface and in fluid communication with the plenum. The system can further include a fluid source configured to move fluid into the plenum and out the plurality of apertures. A method of transferring a patient can include moving fluid into the plenum and out the plurality of apertures to form a fluid pallet. A method of controlling patient temperature can include moving a temperature-controlled fluid into the plenum and out the plurality of apertures.
