A blood glucose measuring device is equipped with a drill device, attachment assembly, and disposable sensing and measurement assembly. The attachment assembly contains an attachment ring that connects to the drill device and is used to hold the disposable sensing and measurement assembly. A detach actuating cam and output shaft are attached to the drill device. Spring tongs are attached to the output shaft by a compression ring further clamp to an end cap. A skin penetrator is attached to the end cap. The disposable sensing and measurement assembly is enclosed in a disposable case. An outer telescoping anti-bend tube is attached to the end cap. An inner anti-bend capillary sensor tube contains analyte sensors and is attached to the disposable case. The electrical conductors for the analyte sensor electrodes are attached to the capillary sensor tube and thus to the disposable case. An impedance sensing electrode on the bottom of the case provides electrical contacts to the skin. The electrical conductor to the impedance sensing electrode is attached to the bottom of the disposable case.

A method of fabricating programmable interlayer conductive links in a multilayer integrated circuit structure, comprising the steps of forming elements of either a conductive or semiconductive material as a lower layer, depositing an insulative layer on top of the lower layer elements, implanting ions into one or more link regions of the insulative layer, forming at least one upper conductor over the implanted regions and selectively applying sufficient energy to at least one of the implanted regions of the integrated circuit structure to render the selected link region conductive. The invention also embraces customized integrated circuit structures with interlayer conductive paths made in accordance with this method.
摘要:
The present invention relates to methods and devices used for the formation of microconduits in a tissue. The term “microconduit” refers to a small opening, channel, or hole into, or through, a tissue, that allows transfer of materials by liquid flow, and by electrophoresis, the microconduit being formed upon impact of a plurality of accelerated microparticles with the surface of the tissue. A method is described for forming at least one microconduit in tissue including the steps of: accelerating a plurality of microparticles to a velocity that causes the microparticles to penetrate a region of tissue surface upon impingement of the microparticles on the tissue surface; and directing the microparticle towards the region of tissue surface, thereby causing the microparticles to penetrate the tissue and form a microconduit in the tissue. According to an embodiment, microparticles are accelerated by being hit with a moving, solid surface. In another embodiment, microparticles are accelerated by a flowing gas or liquid. Also described are methods and devices for using microconduits to deliver therapeutic molecules and ions into tissue, or for extraction of chemical analytes out of tissue. Also described is a method of nail piercing to accommodate jewelry.

摘要:
Devices for applying an intermittent pressure to a skin surface are provided. The device includes a housing, a drive mechanism at least partially disposed within the housing, and a pressing portion operatively coupled to the drive mechanism. The pressing portion may include at least one pressing element configured for applying pressure to the surface. The pressing portion is configured to be driven by the drive mechanism between a first configuration having a maximum extension and a second configuration having a minimum extension. The difference between the maximum and minimum extensions is greater than or equal to 0.025 inches. The pressing portion may include a series of rollers to press and squeeze the skin and underlying vein, to create a pumping action, thus pressurizing the vein. The vein expands and presses upward against the skin, thus becoming more visible.
摘要:
Lead connections and packaging for integrated circuits are formed by processing elongated ribbon arrays of integrated circuit dice in groups prior to cutting the ribbon along its length to free the discrete integrated circuit products. The ribbon is adhered to the base of an elongated channel having at least one leg containing implanted lead-in conductors arranged therein as an axial series of axial arrays of conductors. The axial arrays are aligned with the circuits on the ribbons and interconnections therebetween are formed as photolithographically defined conductive coatings on a top surface of the ribbon extending from bonding pads of the integrated circuit to exposed conductor ends at a top end(s) of the leg(s). The channel ribbon assembly is cut into discrete circuits after forming such interconnections for all the circuits of the ribbon as a group. Each array of lead-in conductors is packed in high density and fans out from the channel to an array of low density lead-out conductors which may be plugged into sockets or otherwise macroscopically treated.
