An aqueous control liquid is provided that contains glucose at a known concentration and cyclodextrin. A method is also provided that binds a wetting agent from a region of a test element that comes into contact with a sample. The method includes contacting the region with a control liquid that has a substance selected from the group of cyclodextrin derivatives and dispersed materials having a specific surface of 100 m2/g to over 1000 m2/g. A method for controlling the function of a measuring system having test strips and a measuring instrument for the determination of glucose in liquid samples is provided that includes contacting the test strip with a control liquid containing glucose at a known concentration and at least one substance selected from the group consisting of cyclodextrins and cyclodextrin derivatives and detecting a signal caused by the glucose contained in the control liquid.

There is proposed a diagnostic test element for detecting an analyte in a sample of a body fluid, more particularly in whole blood. The diagnostic test element comprises at least one test field having at least one detection reagent, wherein the detection reagent is set up to pass through at least one detectable change in the presence of the analyte, more particularly an optical change. The test field has at least one detection layer which comprises the detection reagent and which comprises particles. At least 90% of all particles of the detection layer have an actual particle size of less than 10 micrometers.

A device for obtaining body fluid is described which has at least one lancet comprising a lancet body and a tip. The lancet has at least one structure with an altered stiffness which can also be referred to as a bending region. This structure preferably has a lower or reduced stiffness than the remaining lancet body such that the lancet can be bent in this region when a force acts thereon. In this process, the orientation of the tip is changed relative to the remaining lancet body. This change in orientation is preferably out of the lancet body plane.

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 μm. 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.

A device is disclosed for obtaining body fluid, in particular blood, comprising a lancing element having a tip for puncturing the skin of a body part and an actuator coupled with the lancing element for a forward and backward movement of the lancing element, where the lancing element can be inserted into the skin up to an optionally adjustable puncture position. The actuator is adapted to drive the lancing element forwardly to a penetration speed of at most 0.7 m/s when the lancing element penetrates the skin.
摘要:
The invention concerns an analytical test element in which the sample liquid is transported from a sample application site to a determination site, where a detection site lies upstream of the sample application site in the transport direction. The analytical test element has at least one surface which is composed of at least one element that can be oxidized with water or an alloy that can be oxidized with water which has been treated by the action of boiling water or water vapor.

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.
摘要:
A system for determining an analyte in a body fluid includes a magazine comprising two partial magazines, one including chambers containing analysis elements having a sample contact zone and a reagent system containing a reagent, whose reaction with the body fluid results in a change of a variable, and another including chambers containing puncturing elements having a tip having a capillary channel, which forms a fluid connection between the tip and a sample transfer zone of the puncturing element. The system may also include an analysis instrument having a puncturing drive for driving a puncturing element on a movement path, a mounting for receiving the magazine such that one chamber of the magazine at a time is located in a functional position, in which a puncturing element in the chamber can be moved by the puncturing drive, and a measuring and evaluation apparatus for measuring the change of the variable.
