摘要： An implantable skin piercing device for connecting an external tube to a catheter tube (4) that can be placed inside the human or animal body comprises a cylindrical base body (6) with an upper region (8) facing away from the body in the implanted state and a lower region (10) facing towards the body in the implanted state, wherein the base body is provided in its lower region with a subcutaneous anchorage (12) intended for subcutaneous insertion and wherein upper connection means (16) for connecting the external tube and lower connection means (18) for connecting the catheter tube are present. The subcutaneous anchorage is formed from a plurality of fixing tabs (14) articulated on the base body, which are pivotable from a radially downwards folded retracted position (E) into a radially outwards folded holding position (H). The lower connection means comprise an adapter piece (20) for the catheter tube which can be inserted into the base body and which cooperates with the fixing tabs in such manner that in an inserted lower stop position, it fixes the fixing tabs in the radially outwards folded holding position (H).

摘要： A fluid sampling system for biotechnological applications, comprises a bioreactor chamber (2) for a fluid culture medium (4) containing cells (6) and further comprising transfer means (8) for transferring controlled amounts of culture medium from said bioreactor chamber to a target container (10). The transfer means comprise: a perfusion probe (12) with a fluid-tight probe housing surrounding an internal probe volume (14) and having an inlet probe aperture (16) and an outlet probe aperture (18); a fluid filtering element (20) sealingly connected to the probe housing and forming a cover of the inlet probe aperture. A fluid connection line comprises a fluid receptacle (30) disposed between the outlet probe aperture (18) of the perfusion probe and the target container (10) and disposed on a weight measuring station (32) configured for acquisition of a weight signal corresponding to the fluid receptacle's momentary weight.
