Abstract: A medical storage assembly for reusable medical equipment includes a main storage bag having an opening, a bottom and an interconnecting wall which is operatively suspended from a mounting member that can be removably secured to a vertical support pole. A pivotable rigid lid member is connected to the mounting member and is configured to enable the closing of the opening of the medical storage bag. The medical storage bag can include a plurality of sub-storage bags that are removably mounted within the main storage bag and are removably connected together to provide open configurations whereby different types of reusable medical equipment can be stored. Alternatively, the main storage bag can hold used blood product containers and can be provided with an exterior compartment member of a configuration to hold medical forms that identify the recipient patient with the used blood product container.

Abstract: The present invention relates to a process for preparing flexible, semi-flexible or rigid polyurethane foam plastics from a polyfunctional isocyanate and a polyhydric compound. More specifically, the invention involves the substitution of some portion of the hydroxy groups on the polyhydric compound with acetoacetate groups. Such substitution reduces the viscosity of the polyhydric resin without effecting the performance properties of the foams. Various substitution levels can be used depending on the desired level of viscosity reduction.
