Abstract:
1. An insertion aid for inserting a cannula of a catheter head into organic tissue comprising: a guide needle fixed to a grip section for removable introduction and stabilizing of the cannula during insertion into the organic tissue; a centering web extending from a lower end face of the grip section provided around and spaced apart from the guide needle and configured for facilitating placement of the insertion aid on the catheter head; a needle guard, comprising two disc-shaped shields anchored in a pivotable manner on opposite sides of the lower end face of the grip section, each of the shields comprising a narrower section anchored at one end to the lower end face of the grip section via a pair of hinges, and at the other end is adjoined by a roof-like wider section, wherein the two disc-shaped shields of the needle guard can be pivoted from a first position oriented substantially perpendicular to the longitudinal direction of the guide needle, for insertion of the guide needle into the cannula, to a second position oriented substantially parallel to the longitudinal direction of the guide needle, for locking the disc-shaped shields together in the second position; and a web section extending from an underside of each of the disc-shaped shield in a direction parallel to the guide needle when the shields are in the first position, wherein a first web section comprises a profile that follows the contours of the roof-like wider section of its respective shield, and wherein a second web section comprises a profile that follows the contours of the roof-like wider section of its respective shield and is slightly larger that the first web section such that, when the shields are in the second position, the second web section encloses the first web section.
