Abstract: A medical patch can comprise a biocompatible substrate and a dry hydrogel precursor layer on the substrate, the dry hydrogel precursor layer comprising an electrophilic-hydrogel precursor having a plurality of electrophilic functional groups and a nucleophilic-hydrogel precursor having a plurality of protonated amine groups and no more than about 2 weight percent water. Both the electrophilic-hydrogel precursor and the nucleophilic-hydrogel precursor are substantially uncrosslinked, and are blended or in direct contact with each other. The medical patches can be formed by coating a melt blend of hydrogel precursors in a dry environment or based on solution coating from a dry, non-aqueous solvent, onto a porous, hydrophilic substrate. The medical patches can be used for placement over a bleeding wound or the like and may function as a hemostatic patch. Shredded patches and compositions mimicking a shredded patch can be placed into a wound defect.

Abstract: Processes for coating medical devices are provided herein. The processes include heating a surface of the particles used to form the coating as the particles are being applied to the medical device. The resulting coating has improved adherence to the medical device, and does not require the use of solvents and/or water, obviating the need for any steps that otherwise might be required to remove these solvents and/or water. Sufficient adherence of the particles to the medical device may also occur without the need for heating the substrate used to form the medical device.

Abstract: A cap is provided for a laboratory vessel. The cap includes a lid that can be rotated relative to the laboratory vessel from a closed position to an open position. The lid includes a shield for at least partly surrounding the open top of the laboratory vessel. Ribs are disposed on outer surfaces of the shield for receiving manual digital pressure for opening and/or closing the lid.

Abstract: A cap is provided for a laboratory vessel. The cap includes a lid that can be rotated relative to the laboratory vessel from a closed position to an open position. The lid includes at least one tab dimensioned and disposed for receiving manual digital pressure for opening and/or closing the lid. The tab is in an offset position to prevent a thumb or forefinger from passing over and in contact with the opening to the vessel. Additionally, the lid includes a shield inwardly from the tab for further preventing contact between a finger and the open top of the vessel.
