Abstract: A blood-collection position indicator facilitating blood collection is provided. An adhesive layer is positioned on the back face of a substrate portion having a convex cross section and a circular planar shape, and at its center, a through hole going through the substrate portion and the adhesive layer is provided to serve as a blood collection hole, thus obtaining a blood-collection position indicator. In the blood-collection position indicator, the protruding portion serves as an attachment part to be attached to the tip of a lancet device, and the protruding portion is inserted into a hole of the tip of the lancet device, thus attaching the blood-collection position indicator to the tip of the lancet device. Adhesive strength of the adhesive layer to the skin is set to be stronger than attachment strength of the attachment part to the tip of the lancet device. Consequently, only the first blood-collection position indicator remains on the skin after the lancet device is used.

Abstract: A data logging system and method in which an implantable medical device transmits logged data to an external data logging device with low energy potential signals. The implantable device generates potential signals modulated with digitally encoded data by operating a current source to cause corresponding electrical potentials that can be sensed at the skin surface by the external data logging device. The data logging device then demodulates the sensed potentials to derive the digital data and stores the data in a data logging storage medium.
