  • Publication number: 20100256047
    Abstract: A method for measuring and managing an analyte (e.g., blood glucose) in a bodily fluid includes storing a therapeutic administration protocol in a memory module of an analyte measurement and management device and measuring the analyte in the bodily fluid sample using an analyte measurement module of the device. The method also includes calculating, with a processor module of the device, a recommended therapeutic agent dosage (for example, an insulin dosage) and a recommended administration time for user-activated delivery of the dosage by employing the therapeutic administration protocol. The method further includes displaying the recommended therapeutic agent dosage and administration time to a user on a visual display of the device, delivering a therapeutic agent dosage to the user via a user-activated therapeutic agent delivery device, and detecting the user-activated administration of the therapeutic agent using a delivery device communication module of the device.

  • Publication number: 20100016700
    Abstract: Various embodiments of a diabetes management system are provided. One exemplary system may include an analyte measurement device and a therapeutic agent delivery device. The measurement device includes a measurement unit, display, and first wireless module. The therapeutic agent delivery device has a delivery device housing, delivery mechanism disposed in the housing that delivers a dosage of the agent to the user upon actuation by the user or health care provider, and a second wireless module. The second module, automatically, without prompting from a user or any active input or action by the user, transmits a signal to the first wireless module indicative of: (a) type of therapeutic agent delivered; and (b) amount of therapeutic agent delivered to the user; or (c) type of therapeutic agent device from which the therapeutic agent was administered. Also described are diabetes management devices and methods.

  • Patent number: 7361307
    Abstract: A device for accessing biological fluid, sampling biological fluid constituents and determining the concentration of at least one target constituent within the accessed biological fluid is provided. The device has at least one micro-piercing member used to penetrate the skin to a selected depth and to access biological fluid, a constituent sampling means and a constituent measuring means. The constituent sampling means comprises a constituent transfer medium, such as a hydrophilic gel material, by which sampled constituents are transferred from the micro-piercing member to the measuring means. The measuring means includes an electrochemical cell having at least one porous electrode through which at least one sampled constituent is caused to enter into the electrochemical cell. Methods of sampling constituents within the skin and measuring the sampled constituents, as well as kits for practicing the invention are provided.

  • Publication number: 20050169810
    Abstract: Devices for dispensing test strips and methods of using the same are provided. The subject devices are characterized by having a housing made of a cover and a base configured to retain a plurality of test strips. In certain embodiments, the height of the base is less than the height of each of the test strips, such that a portion of each of the test strips extends beyond the distal or top edge of the base. The subject devices may further be characterized as having a substantially air and moisture tight seal. In using the subject devices, a plurality of test strips stored in a subject device are provided. A single test strip is removed from the subject device by moving the test strip distal to the remaining test strips. Also provided by the subject invention are kits for use in practicing the subject methods.

  • Patent number: 5230866
    Abstract: A capillary stop-flow junction located in a housing at an end of a capillary passageway used to transport a liquid and at the beginning of a non-capillary internal chamber in the housing, in which the stop-flow junction contains an improvement which comprises 1) means for selectively trapping a gas in the capillary passageway and non-capillary chamber, wherein when the means for trapping is activated and the liquid enters the capillary passageway, the gas is compressed by the liquid as the liquid flows through the capillary channel and stops flowing at the stop-flow junction; or 2) a stop-flow nozzle surrounding the capillary passageway and projecting into the chamber; or 3) the stop-flow junction being formed from a single housing body member; or 4) a rupture junction in the capillary pathway, wherein the rupture junction is a stop-flow junction providing less maximum available back pressure than the capillary stop-flow junction.
