A multi-parameter catheter (1) for the in vivo determination of multiple parameters in a patient's blood comprising an elongated tube with a distal hollow chamber (5) terminating in a distal end (3) the wall of said chamber being defined at least in part by a biphasic membrane (2) made from a layer of microporous hydrophobic substance having micropores which are filled with a hydrophilic substance which when hydrated forms a gel which allows the passage of water-bound ions and said chamber containing a plurality of sensors (7, 8, 9, 10) mounted sequentially from said distal end within a hydrophilic medium. |
