The fluid receiving means may have a test zone for performing an analytical reaction. Fluid sample from the collection zone is automatically or manually transported to the fluid receiving means to contact the fluid with the test zone.

Abstract: A lancing device for generating a puncture wound in a body part to obtain a body fluid sample for analytical or diagnostic purposes, in particular, by using integrated disposables that comprise a lancing element as well as an associated test element is disclosed. In order to achieve a high success rate in obtaining the body fluid sample, a drive can be designed such that the lancing element or the test element can be moved into a contact position while remaining in a position near the body part contact opening during a deployment period. If the amount of sample obtained in a lancing movement is inadequate to carry out the analysis or diagnosis, the lancing element can be brought into contact with the sample by a user by manual positioning the lancing device to manually take up a sample obtained by manually milking the sampling site in the region of the puncture wound.

Abstract: The present invention provides a portable blood sugar measuring device comprising a tape unit for winding a test tape forward in sections, a detection unit for detecting measured values on the sections of tape to which body fluid has been applied, and a housing to hold the tape unit and detection unit.
