摘要:
The invention relates to a device for taking and analyzing a blood sample, comprising an integrated drive unit having a common drive source and a driving-force transmitting gear train, by means of which a lancet drive, an apparatus for advancing a magazine (4), and a sample transmitting apparatus (12) can be coupled to the drive source. A stressing rotor (18) and a drive rotor (20) are rotatably mounted coaxially to each other. A first cam control converts the rotation of the drive rotor (20) into a radial forward and backward motion of a driving rod (9). A second cam control converts the rotational motion of the stressing rotor (18) into a linear motion of a slotted-link slider (11). A switching slotted link (34) moved by the slotted-link slider (11) rotates the magazine (4) one step further. A third cam control converts the rotational motion of the stressing rotor (18) into a linear motion of a push rod (37) perpendicular to the pricking axis.

The invention relates to a method for producing a hole in the skin in order to remove a body fluid sample from the body part, wherein an opening (21) is produced on the skin on the point of the hole in the epidermis (20) in the skin-opening step. Then, a sample removing hole is created by means of a pricking element (11) in the sample removing step, wherein the skin opening (21) is deepened by means of the pricking element (11) and then a hole, which is used to remove the sample, is produced. The invention also relates to a hand-held device for carrying out said method.

The invention relates to a measuring device for the optical analysis of a diagnostic test strip (10). Said device comprises a light source (16), a photo-detector (24) and a device (12) for positioning the test strip (10) between the light source (16) and the photo-detector (24). The light source (16) comprises one or more organic light-emitting diodes (OLEDs) and the OLEDs (14) form a composite structure with imaging optics (20) and/or the photo-detector (24) by means of a support substrate (18).
摘要:
The invention concerns a system for monitoring the concentration of analytes in body fluids, in particular in interstitial fluid and comprises a catheter having an implantable region and an outlet opening for withdrawing fluid in particular body fluid. A first and a second analytical zone are contacted sequentially with fluid from the catheter and undergo a detectable change when an analyte is present. The analytical zones can be contacted manually with fluid and also preferably in an automated fashion by means of a device. A system according to the invention additionally has an analytical device for analysing the analytical zones in order to determine the concentration of the analyte on the basis of changes caused by the analyte. A further subject matter of the present invention are catheters for use in systems according to the invention as well as magazines containing test zones.
