Abstract:
1. A lancing device for generating a puncture wound in the skin of a human or animal to obtain a sample of a body fluid with a first analytical consumable which comprises a lancing element for carrying out an analysis of a medically significant component of the sample with a second analytical consumable which comprises a test element, wherein the lancing device comprises: a pressing member for pressing the lancing device against a body part in which it is intended to generate a puncture wound with the lancing element at a sampling site from which a sample is to be taken; a drive for driving a lancing element inserted into the lancing device for a lancing movement of the lancing element along a predetermined lancing path into a lancing position, wherein the lancing movement comprises a rapid puncture movement which is directly followed by a return movement; a housing with a body part contact opening for the body part, wherein the lancing element is disposed in the housing in an initial position and at the body part contact opening it can be pierced into the applied body part in the lancing position by actuating the drive; and a control device configured for checking a collected sample with regard to whether the amount of sample obtained and taken up by the lancing device is sufficient for carrying out the analysis with a test element, wherein the drive is configured such that in a first step the lancing movement can be carried out with a lancing element to generate a puncture wound at a sampling site for obtaining a sample, and wherein the lancing device is configured such that after the lancing movement the control device can be used to check whether the amount of sample obtained and taken up by the lancing device is sufficient to carry out the analysis with a test element, and wherein the drive is configured such that in a further step at least one of the analytical consumables can be moved in an extending movement into a contact position in which the analytical consumable remains in a position in the region of the body part contact opening during a deployment period, in which the analytical consumable can be brought into contact with the sample by a user of the lancing device by a manual positioning of the lancing device to manually take up a sample which has been expressed by manually milking the sampling site in the region of the puncture wound, if according to the result of the check carried out by the control device, the amount of sample obtained in the lancing movement is not sufficient to carry out the analysis, and wherein the extending movement differs from the puncture movement in that the analytical consumable remains in the contact position for a longer time than in the lancing position such that in the contact position it can be brought into contact with the sample by the user of the lancing device during the deployment period by a manual positioning of the lancing device to manually take up a sample which has been expressed by manually milking the sampling site in the region of the puncture wound.
