  • Publication number: 20090137931
    Abstract: A lancet integrated test element tape includes a plurality of lancet integrated test elements. The lancet integrated test elements each include a lancet configured to form an incision in tissue and a test element configured to analyze body fluid from the incision in the tissue. A cartridge includes a supply compartment configured to store an unused section of the tape. The tape is folded within the supply compartment to limit damage to the lancet integrated test elements. The cartridge can further include a waste compartment in which a used section of the tape is stored. An indexing mechanism moves the tape between the supply and waste compartments.

  • Publication number: 20090131828
    Abstract: A body fluid sampling device is used to sample a bodily fluid from an incision in skin. The device includes a housing that defines a sample cavity with one open end that contacts skin. The device also includes a lancing mechanism that forms an incision in the skin. A vacuum mechanism is used to create a vacuum inside the sample cavity to express fluid from the incision site. To release the vacuum, a valve is connected with the sample cavity to exchange atmospheric air and further works to minimize fluid splatter. The fluid sample can then be tested or analyzed as desired.

  • Publication number: 20090124930
    Abstract: A body fluid sampling device includes an expression member placed around an incision in the skin of a user, a compression member to contact and traverse the expression member, and a housing configured to contact the skin near the incision. The expression member is configured to repeatedly move from a relaxed position over the incision to a contracted position over the incision. The expression member is at least partially resilient in order to repeatedly squeeze and/or compress the skin around the incision.

  • Publication number: 20090124933
    Abstract: A unique technique for maintaining the sterility and integrity of a lancet tip. One or more lancet tips are sandwiched between a first web and a second web of material to protect the sterility of the lancet tips. The first and second webs are heat fused together to form a structure that covers and encapsulates the lancet tips to protect the integrity of the lancet tips. The structure is cut to form individual protective caps to detachably cover each of the lancet tips.

  • Publication number: 20090036797
    Abstract: A lancet enclosed in a sterility sheet forms a lancet packet to maintain the sterility of the lancet and prevent the lancet from unintentionally piercing the sterility sheet prior to lancet actuation. In one form, the lancet is immobilized by hot tack welding a portion of the sterility sheet to the lancet. Alternatively, portions of the sterility sheet are hot tack welded together through an opening in the lancet to limit movement of the lancet.

  • Publication number: 20090010802
    Abstract: An integrated disposable includes a test strip and a lancet packet coupled to the test strip. The lancet packet includes a sterility sheet enclosing at least a portion of a lancet to maintain the sterility of the lancet. The lancet packet and the sterility sheet, in particular, allow the lancet to be sterilized separately from the test strip. The lancet in one form is incorporated into a lancet tape that is sterilized in a continuous, reel-to-reel sterilization process. The lancet tape in one form is sterilized using an electron beam sterilization process. With electron beam sterilization, sterilization is enhanced by irradiating both sides of the tape with electron beams. Sterilization can adversely affect chemical reagents in the test strip. To alleviate this chemistry degradation issue, the lancet packet is attached to the test strip after the lancet is sterilized.

  • Patent number: 7384402
    Abstract: An integrated body fluid sampling device is used to sample a body fluid from an incision in the skin of a body part. The device includes a lancet for forming the incision in the skin. A housing is coupled to the lancet. The housing defines at least in part a capillary channel with an opening. The capillary channel is sized to draw the body fluid from the incision via capillary action. An expression pad is coupled to the housing. The expression pad has opposing angled sides for compressing the backside of a body part where the incision is made. The lancet extends from the housing to form the incision. Fluid from the incision is drawn into the channel and is deposited on the test strip for analysis. A test strip is positioned along the capillary channel for analyzing the fluid.

  • Publication number: 20070173739
    Abstract: A meter system for analyzing body fluids includes a supply magazine for storing a stack of test elements, a meter for analyzing fluid samples, and a transport system for transporting test elements from the supply magazine to the meter. The test element in one embodiment includes a lancet integrated test element that has a lancet coupled to a test strip. The transport system is configured to minimize damage to the test element. In one form, the transport system includes a shuttle that slides the top-most test element from the stack onto a connection portion of the meter. In another form, the transport system includes a drum that rotates to transport test elements from the supply magazine to a testing position and, once used, to a waste magazine for disposal. In a further form, the transport system includes a disc that rotates to transport the test elements.

  • Publication number: 20060229532
    Abstract: An integrated lancing test strip device includes a lancet configured to form an incision in tissue and a test strip coupled to the lancet for analyzing body fluid. A retention mechanism acts as a detent to hold the lancet in a static position relative to the test strip before forming the incision. The retention mechanism is configured to release the lancet for retracting the lancet relative to the test strip to reduce smearing of body fluid by the lancet during collection of the fluid with the test strip. In one form, the retention mechanism includes breakable tabs that are broken to release the lancet, and the lancet is retracted via translational movement. The retention mechanism in another form includes one or more dimples that release the lancet when the lancet is retracted via rotational motion. In a further form, the entire integrated device is rotated to collect fluid.

  • Publication number: 20060159108
    Abstract: A communication method for execution at a customer premises device, comprising detecting receipt of a command indicative of an intent of a management entity to initiate a management session, the command being a management session initiation command. Responsive to detecting receipt of the management session initiation command, an identifier for participating in a management session with the management entity is obtained. Also, a method for execution at a management entity, comprising obtaining a management address for a customer device and determining whether the management address is indicative of a an address capable of supporting a management session or an address incapable of supporting a management session. If the management address is indicative of an address incapable of supporting a management session, a command is sent to the customer device, causing it to obtain a management address capable of supporting a management session.

  • Publication number: 20060159243
    Abstract: Apparatus for establishing a packet-based connection between a video display equipment (such as a set-top box) having an analog modem and a remote computer. The translation apparatus receives a connection initiation request from the video display apparatus and responsive to the connection initiation request establishes a modem connection with the video display apparatus. The translation apparatus further receives communication data from the video display apparatus via the modem connection and transmits the communication data to the remote computing apparatus via a packet-based network. The translation apparatus can also receive communication data from the remote computer and relay the same to the video display apparatus. The connection can be established upon powering up of the video display apparatus, upon loading of an Interactive TV application or upon other pre-determined event. The connection can be maintained “always-on” or substantially “always-on”.
