Abstract
An invasive blood parameter probe includes a flexible pressure tube which surrounds the sterile probe portion. When the pressure tube is stretched, the proximal probe tip slips into the pressure tube. Pressure tube is held in its elongated position by means of an--e.g. U-shaped--spanning member against which a Y-connector and a threaded sleeve abut. A container may now be replaced, under sterile conditions, by a catheter.
