Abstract

A guide means is formed on the needle holder for a catheter head by a guide sleeve axially surrounding the connecting needle, the guide sleeve being pushed or narrowly slide-guided over a cylindrical extension of the cannula housing upon the needle holder and the cannula housing being connected, i.e. upon the connecting needle being introduced. The cylindrical extension surrounds the inlet and a section of the passage channel of the cannula housing connected to the same. The invention ensures secure introduction of the connecting needle without the need of forming additional guide pins. In addition, the guide sleeve represents a means of protection for handling, both for the needle and the user. The guide sleeve may have openings, but is preferably designed as a closed sleeve body.
