20080269639 | Device for obtaining bodily fluids for analysis - A lancing device for piercing skin to obtain a bodily fluid, such as blood, for testing has an electrically activated actuator, such as a shape memory alloy or electro-active polymer, that changes shape upon the application of electrical energy to advance and withdraw the lancing element. The lancing device operates when the actuator changes shape to advance a lancing element to pierce the skin when the actuator changes shape, delaying the lancing element tip near the advanced position to allow fluid to flow into the lancing tip, withdrawing the lancing element to remove the lancing element form the skin when the actuator again changes shape. | 10-30-2008 |
20080294064 | Lancing Element, Lancing System and a Method for Skin Detection - In the case of a disposable lancing element for collecting body fluid through the skin comprising a support and a lancing member which distally projects therefrom and can pierce the skin in a lancing movement, it is proposed that a pretensioning means which tightens the skin in the area of the puncture site is arranged on the support and has a contact member which impacts the skin laterally from the lancing member during the lancing movement. | 11-27-2008 |
20090093735 | Test unit and test system for analyzing body fluids - The test unit for analyzing body fluids such as blood comprises a collecting element which has a microfluidic collecting area for the body fluid, and a test element which can be brought into fluidic connection with the collecting area by deflecting a transfer part of the collecting element in order to transfer body fluid. The transfer part is pre-tensioned against a holding-down device and the deflection of the transfer part towards the test element can be triggered by releasing the holding-down device. | 04-09-2009 |
20110028862 | METHOD AND DEVICE FOR THE EXTRACTION OF A BODY FLUID - The present invention provides a method and a device for piercing a body part and determining whether a sufficient volume of blood has been withdrawn. A lancing element is rapidly inserted into a body part in a forward phase and retracted quickly to a lesser puncturing depth. Subsequently, the lancing element is retracted slower than during the first retraction movement and the distance retracted during the second retraction is shorter than the first retraction movement. During the second retraction movement, body fluid is collected in a collection phase by a capillary structure of the lancing element. Contact between the lancing element and the body fluid is detected after the forward phase at the beginning and the end of a waiting period. | 02-03-2011 |
20110124128 | Centrifugal Force Based Microfluidic System And Method For The Automated Analysis of Samples - Centrifugal force based microfluidic systems for the automated analysis of fluids involving the use of magnetically responsive particles and methods thereof are disclosed. A magnet is fixed to a supporting device of the system in correspondence to a retention zone of the system so as to rotate therewith and to generate a magnetic field which magnetically manipulates the magnetically responsive particles contained in a reaction chamber of the system. | 05-26-2011 |
20110136109 | System And Method For Cycling Liquid Samples Through A Series Of Temperature Excursions - A system and method for cycling liquid samples through a series of temperature excursions are disclosed. Provided are open-top reaction vessels for containing the samples, which may be enclosed by one or more covers. A temperature-controlled block for generating or adsorbing heat is coupled thermally to the reaction vessels. A detection arrangement is disposed in an emission beam path to detect radiation emitted from the samples through the covers. A heating arrangement for generating heat includes a heating element that is both disposed between the reaction vessels and the detection arrangement and coupled thermally to the covers. The heating element includes an optically transparent substrate provided with one or more opaque heating lines, the heating lines being disposed in the emission beam path in a manner to obtain a predetermined minimum optical transmission of the heating element. A controller, set up to control cycling of the samples, is provided. | 06-09-2011 |
20120230885 | BENT MICROSTRUCTURES FOR SAMPLING, TRANSPORTING OR DISPENSING A FLUID MEDIA - A device for sampling, transporting and/or disposal of fluid media in the nl and μl-range comprises a substrate with an open or closed capillary-like groove or channel respectively, the substrate with the open or closed groove or capillary respectively is bent or arcuated at least at one location. The substrate comprises at least one end into which the open or closed capillary-like groove or channel respectively is extended, which end is shaped according to its application or use as e.g. needle-like, straight-lined cut, tip-like, at least most half circle-shape, rounded, etc. | 09-13-2012 |
20130183212 | BENT MICROSTRUCTURES FOR SAMPLING, TRANSPORTING OR DISPENSING A FLUID MEDIA - A device for sampling, transporting and/or disposal of fluid media in the nI and μl-range comprises a substrate with an open or closed capillary-like groove or channel respectively, the substrate with the open or closed groove or capillary respectively is bent or arcuated at least at one location. The substrate comprises at least one end into which the open or closed capillary-like groove or channel respectively is extended, which end is shaped according to its application or use as e.g. needle-like, straight-lined cut, tip-like, at least most half circle-shape, rounded, etc. | 07-18-2013 |
