    摘要: A medical needle assembly includes a stylet having non-circular cross-sectional shape disposed within the needle lumen. The needle and the stylet each define respective electrodes that enable ascertainment of an electrical property of a body substance adjacent the distal tip of the needle. An electrically insulative coating having a uniform thickness covers the stylet. Wire leads enable connection of the electrodes to a measurement module configured to measure an electrical property of a body substance adjacent a distal end of the needle during insertion. Electrical property measurement enables identification of the location of the needle tip within the patient based on the measurement value. A major diameter of the non-circular cross-sectional shape extends across the needle lumen to create first and second flow paths extending along the lumen on opposite sides of non-circular cross-sectional shape. The first and second flow paths enable blood to flow along the lumen during use.

    摘要: Systems and method for remote field measurement-based mapping of anatomical structures (e.g., using impedance image of electrical fields) are described. In some embodiments, an image of features within a target region is produced by analysis of a spatial pattern of field measurements made in a measurement region remote from the target region features; for example, but not exclusively, by treating the spatial arrangement of field measurements in some portion of the measurement region as indicating the spatial (e.g., angular and/or distance) arrangement of features (e.g., anatomical structure of topography and/or tissue type) in the target region.

    摘要: A moisture measuring device includes a biosensor, a processing unit, a substrate, a housing, and one or more attaching members. The biosensor has a sensor surface for acquisition of biological information. The processing unit is configured to process the biological information acquired by the biosensor. The substrate has a first principal surface on which the processing unit is mounted. The housing accommodates the biosensor, the processing unit, and the substrate. The one or more attaching members are disposed on the first principal surface side of the substrate to attach the substrate to the housing. The total area of one or more overlap regions in which the one or more attaching members overlap the substrate in the first principal surface of the substrate when viewed in a direction perpendicular to the first principal surface of the substrate is smaller than a sensor area of the sensor surface of the biosensor.
