Patent number: 8852124Abstract: A lancet-sampler system is configured to automatically remove a protective cover from a lancet and automatically unpack a test pad just prior to use. This minimizes the risk of injury and reduces the chance of cross-contamination between the lancet and the test pad. The lancet defines a capillary groove for drawing body fluid from the incision via capillary action and a sample transfer opening for collecting the fluid from the groove. A carrier tape is coupled to the lancet. The carrier tape includes a test pad for analyzing the fluid. The tape is folded around the test pad to form an airtight package. The test pad is located at a position to align with the sample transfer opening when the tape is unfolded. The protective cover covers a portion of the lancet, and when the tape is pulled, the protective cover is automatically pulled from the lancet.Type: GrantFiled: June 2, 2011Date of Patent: October 7, 2014Assignee: Roche Diagnostics Operations, Inc.Inventors: Steven N.

Patent number: 8814808Abstract: Body fluid sampling device comprising a skin-piercing element having a collection zone for receiving body fluid. In one embodiment, the collection zone includes a plurality of holes, e.g., 3 or more holes, or 50 to 100 holes. The hole size may be small, e.g., having a diameter of 0.01 to 0.5 mm. The holes may or may not extend through the lancet. In some embodiments, the holes have a depth of 50 to 500 ?m. In other embodiments, the collection zone is porous, or is a roughened area. The collection zone can take up a very small volume of body fluid, e.g., 3 to 10 nL, in a very short time period, e.g., less than 0.5 seconds. In other embodiments, the device further comprises a fluid receiving means spaced apart from the collection zone so that body fluid in the collection zone will not contact the fluid receiving means initially.Type: GrantFiled: September 10, 2010Date of Patent: August 26, 2014Assignee: Roche Diagnostics Operations, Inc.Inventors: Irio Guiseppe Calasso, Patrick Griss, Emad Sarofim, Rainer Jaeggi, Uwe Kraemer, Dave Hasker, Volker Zimmer, Wilifried Schmid, Otto Fuerst, Hans List, Hans-Peter Haar, Theo Arnitz, Steven N.

Patent number: 8444574Abstract: Lancing system comprising a needle and a lancing device The lancing device comprises a housing with a housing opening that is surrounded by a housing skin contact surface. A lancing depth reference element with a reference skin contact surface is adapted in such a manner that the reference skin contact surface at a reversal point of the lancing movement is in contact with the skin. The lancing depth is determined by the distance between the reference skin contact surface and the tip of the needle element at the reversal point of the lancing movement. The lancing depth reference element is in a stationary defined position relative to the reversal point of the lancing movement. The lancing depth reference element is adapted to stabilize the skin when pressed against the reference skin contact surface with respect to a skin deformation which occurs upon lancing of the skin.Type: GrantFiled: March 3, 2009Date of Patent: May 21, 2013Assignee: Roche Diagnostics Operations, Inc.Inventors: Hans List, Irio G.

Patent number: 8394035Abstract: The invention concerns a device for collecting body fluids which has at least one lancet comprising a lancet body with at least two tips of different lengths. The device is characterized in that it has a selection means with the aid of which only one tip is selected before the lancing. This selection means can have different functions and shapes. The selection means is used to select a tip from a plurality of lancet tips which have different lengths and make only this tip available for use in the lancing process. Since the various tips are attached to a lancet body, it is, for example, possible to use a bending element which bends one of the various tips out of the plane of the lancet body in order to provide only one lancet tip for use. This is especially preferable for lancet tips that are arranged linearly relative to one another.Type: GrantFiled: January 21, 2009Date of Patent: March 12, 2013Assignee: Roche Diagnostics Operations, Inc.Inventors: Hans-Peter Haar, Herbert Harttig, Joachim Hoenes, Hans-Juergen Kuhr, Ortrud Quarder, Dirk Voelkel, Volker Zimmer
