    • 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.
    • 将含水基流体生物材料样品中的成分与样品的水性成分分离,并浓缩在检查仪的焦平面上,在此可以在放大倍数下进行检查。 可以以这种方式分析的流体的实例包括尿液; 脑脊液 胸膜液 腹水; 从囊肿如甲状腺和乳腺囊肿吸出的液体; 已经置于水性液体中的细胞学标本; 血小板富集血浆 等等。 将样品放置在具有覆盖室的表面的亲水性水凝胶层的室中。 室的相对表面是透明的,并且可以由显微镜滑盖盖等形成。 腔室中的水凝胶的体积是足够的,使得当水凝胶基本上吸收样品的所有含水部分时,水凝胶将膨胀并填充室。 膨胀的水凝胶的捕获表面优选是平面的,并且样品中的任何形成的成分将被捕获在水凝胶层的捕获表面上,并且不会被吸收到水凝胶中。 形成成分,如:细胞; 菌; 晶体 原生动物 奥娃 寄生虫 可以通过使用标记的抗体,选择性污渍等差异地突出显示,以便能够对可能在样品中的各种形成的成分进行光学检查和分化。 可以从膨胀的水凝胶层的捕获表面收获成形成分,以进行更详细的检查和分析。 水凝胶的捕获表面可以设置有多个珠子,用于使用光学扫描仪器来定位捕获表面,并且用于重建先前扫描的视场。

    • 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 crosslinked 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.
    • 用于离子电渗药物递送装置的本发明的储存器电极组件包括位于与电极导电关系的电极和亲水性储存器。 亲水性储存器由具有粘附到电极的第一表面和第二表面的吸水性亲水性交联聚合物材料形成。 当应用于患者皮肤区域时,聚合物材料的第一表面可剥离地粘附。 聚合物材料具有内聚强度,其形成粘合剂粘合,聚合物材料的第二表面与电极之间的粘合强度大于聚合物材料的内聚强度。 此外,聚合物材料的第一表面与患者的施用区域的粘合粘合强度小于聚合材料的内聚强度,使得当从患者的施用区域移除本发明的储器组件时, 基本上没有聚合物材料保留在施加的区域上,并且亲水性储存器保持基本上完整且粘附到电极上。
