    摘要: A reservoir electrode assembly of the present invention for an iontophoretic drug delivery device includes an electrode and a hydrophilic reservoir situated in electrically conductive relation to the electrode. The hydrophilic reservoir is formed from a bibulous hydrophilic cross-linked polymeric material having a first surface and a second surface that is adhesively adherent to the electrode. The first surface of the polymeric material is releasably adhesively adherent when applied to an area of a patient's skin. The polymeric material has a cohesive strength forms an adhesive bond with a bond strength between the second surface of the polymeric material to the electrode that is greater than the cohesive strength of the polymeric material. Additionally, an adhesive bond strength of the first surface of the polymeric material to the applied area of the patient is less than the cohesive strength of the polymeric material so that upon removal of the reservoir assembly of the invention from the applied area of the patient, substantially no polymeric material remains on the applied area and the hydrophilic reservoir remains substantially intact and adhesively adherent to the electrode.

    摘要: A method for testing the ability of an iontophoretic reservoir-electrode to deliver a medicament includes providing an iontophoretic reservoir-electrode with a contact surface having a shape, a suitable electrical connection and a hydrated bibulous reservoir containing an ionized medicament. The method further includes providing another electrode operating a at preselected polarity opposite to the preselected polarity of the medicament reservoir-electrode. The method further includes providing a separation medium having the property of allowing passage therein to of ions of one charge. The separation medium is positioned between the reservoir electrode with the ionized medicament and the another electrode. The method also includes applying a sufficient electrical potential between the iontophoretic reservoir-electrode containing the ionized medicament and the another iontophoretic reservoir-electrode so that a current flows through the separation medium for a preselected time thereby transporting a quantity of the ionized medicament into the separation medium. The method then includes determining an amount of the ionizable medicament in the separation medium.

    摘要: Formed constituents in an aqueous based fluid biologic material sample are separated from the aqueous constituent of the sample, and are concentrated in an examining instrument's focal plane where they can be examined under magnification. Examples of fluids that can be analyzed in this fashion include urine; cerebrospinal fluid; pleural fluid; ascites; fluids aspirated from cysts such as thyroid and breast cysts; cytologic specimens which have been placed in an aqueous fluid; platelet-rich plasma; and the like. The sample is placed in a chamber having a layer of a hydrophilic hydrogel covering a surface of the chamber. An opposite surface of the chamber is transparent, and may be formed by a microscope slide cover slip, or the like. The volume of hydrogel in the chamber is sufficient so that, when the hydrogel absorbs essentially all of the aqueous fraction of the sample, the hydrogel will expand and fill the chamber. The capture surface of the expanded hydrogel is preferably planar, and any formed constituents in the sample will be captured on the capture surface of the hydrogel layer, and will not be absorbed into the hydrogel. Formed constituents, such as: cells; bacteria; crystals; protozoa; ova; parasites; and the like, can be differentially highlighted by use of labeled antibodies, selective stains, or the like, so as to enable optical examination and differentiation of various formed constituents which may be in the sample. Formed constituents may be harvested from the capture surface of the expanded hydrogel layer for more detailed examination and analysis. The capture surface of the hydrogel may be provided with a plurality of beads for use in locating the capture surface with an optical scanning instrument, and for re-establishing previously scanned fields of view.
