Device for conducting in vivo measurements of quantities in living organisms

摘要

In a device (10) for in-vivo measurements of quantities in living organisms that comprises a catheter-like tube (11) receiving in a removable manner a setting needle (14) provided for inserting the tube in the organism, with at least one aperture (12) being provided in the wall of the tube (11); and a sensor (18) for detecting the quantity to be measured in the interior of the tube; the sensor (18) is mounted on a separate oblong carrier (17) whose cross sectional dimensions are smaller than those of the interior of the tube. After the setting needle (14) has been pulled out of the tube (11), the sensor can be inserted in said tube (11).
