The disclosed medical dressing has a dressing body and a flap. The dressing body has a first major surface and opposite second major surface containing a skin-contact adhesive. The flap has a fixed end integrally connected to the dressing body and a movable free end. The second major surface of the flap has a securing adhesive for contact with the first major surface of the dressing body.

Medical dressing comprising a flap

A medical dressing () with a dressing body () and a flap (). The flap can include a fixed end () coupled to the dressing body, and a free end () movable with respect to the dressing body between a first position and a second position in which the free end is positioned in overlapping relationship with the dressing body. A second major surface () of at least the free end of the flap can be configured to be secured to the dressing body, and the flap can be located toward a proximal end of the dressing body, such that a distal portion of the dressing body is free of the flap. The dressing body can be adhered to skin with a skin-contact adhesive (e.g., a silicone adhesive) (), and the flap can be secured to the dressing body with a securing adhesive (e.g. an acrylate adhesive) () that can have a higher adhesion or adhesive strength.

Devices, methods and systems for low volume microarray processing are disclosed. The microarray devices preferably include a plurality of reactant sites on a reactant surface. The reactant sites include reactants that operate to capture one or more selected analytes that can then be detected based on an electromagnetic signal, e.g., fluorescence, that is emitted by each analyte in response to excitation energy incident on the microarray device. Mixing and/or distribution of the analyte sample over the reactant surface is accomplished by tilting the reactant surface such that the analyte sample flows over the reactant surface under the force of gravity. The tilting is performed such that a portion of the analyte sample accumulates in a bead along a first edge of the reactant surface. The reactant surface is then tilted in a different direction such that a portion of the analyte sample flows over the reactant surface and accumulates at a second edge. The reactant surface preferably generates sufficient capillary forces with the analyte sample such that the analyte sample is retained on the reactant surface. The tilting and resultant flow may be performed as many times as necessary to obtain the desired mixing and/or distribution of analyte sample over the reactant surface.
