  • Patent number: 11041846
    Abstract: A test element analysis system for the analytical examination of a sample is disclosed. The test element analysis system comprises: at least one evaluation device with at least one test element holder for positioning a test element containing the sample and at least one measuring device for measuring a change in a measuring zone of the test element, the change being characteristic for the analyte; at least one electrical heating element configured for electrically heating the test element; at least one electrical power supply for supplying electrical energy to the electrical heating element; at least one temperature sensor connected to the test element holder for detecting a temperature of the test element holder; at least one gap detection device configured for monitoring the electrical energy Espez supplied by the electrical power supply to the electrical heating element for reaching a predetermined target temperature measured by the temperature sensor.

  • Publication number: 20210109088
    Abstract: Methods, devices and systems for detecting an analyte in a body fluid are described. A sample of body fluid is applied to a test element having a test field including a test material adapted to change a measurable property in the presence of the analyte. The test element includes a capillary to guide the sample across said test field. The measurable property is measured in a first measurement location providing a first measurement value, and in a second measurement location providing a second measurement value. The analyte is detected by using an evaluation algorithm having at least a first input variable including a difference between the first measurement value and the second measurement value, and at least a second input variable including information relating to an analyte-induced change of the measurable property of the test material in at least part of the test field.

  • Patent number: 10900957
    Abstract: Methods for detecting an analyte in a body fluid are described as well as devices and systems adapted for performing such methods. In embodiments of the method, a sample of body fluid is applied to a test element having at least one test field including at least one test material that is adapted to change at least one measurable property in the presence of the analyte. The test element further includes a capillary to guide the sample across said test field in a flow direction. The test element also includes first and second measurement locations offset from each other in the flow direction. The measurable property is measured in at least one first measurement location, providing at least one first measurement value, and it is measured in at least one second measurement location, providing at least one second measurement value.

  • Patent number: 6854772
    Abstract: A plug connection for hoses or pipes as for connecting washing fluid conduits in a motor vehicle comprises a plug receiving member for receiving a connecting plug portion. The connecting plug portion can be latched in the plug receiving member in such a way as to be secured against forces acting axially thereon. The plug receiving member has resilient or spring-loaded latching portions. A securing sleeve is arranged axially slidably on the outside of the plug receiving member. In a first position of the securing sleeve the latching portions are held in a receiving and latching position in which a connecting plug portion can be inserted into and latched in the plug receiving member. In a second position of the securing sleeve it permits the latching portions to move resiliently into a retracted open position for disengagement of an inserted connecting plug portion from the plug receiving member.
