Abstract
A dialytic probe is provided with an insertion needle sharpened at one end, which is surrounded by a flexible plastic cannula, and may be removed after introduction of the probe. The plastic cannula is covered at least partly by a tubular dialyzing membrane which is bonded to the plastic cannula at the distal end and to a handle at the other end, thus forming a fluid-tight seal. The space between the plastic cannula and dialyzing membrane is divided along the length of the probe, such that two passages or lumens of essentially crescent-shaped cross-section are formed, with a flow-connection at the distal end of the plastic cannula, and with a connection to one of separate ingoing and outgoing lines each. The lumen of the plastic cannula may be connected to a drug feeder line. The handle holds the ingoing and outgoing lines and a potential drug feeder line of the probe.
