Device for catheterization in particular for perfusions in the medical and veterinary fields

摘要

A needle for "tunnelization" beneath a patient's skin and subsequent perfusion is attached to a flexible catheter tube by means of a fastening device comprising a rigid tube having the same internal diameter as the flexible tube. A needle constriction serves to clamp the end of the flexible tube against the rigid tube without producing any reduction in internal diameter of the flexible tube.
