PUNCTURING AND CATHETERIZING DEVICE FOR THE HUMAN OR ANIMAL BODY

摘要

A puncturing and catheterizing device for the human or animal body with a metallic puncture needle and a cannula which surrounds the puncture needle in the region between its point and rear end and through which, after the puncture needle has been pulled out, a longer guidewire can be inserted into the body, which then, after the cannula has also been pulled out, serves as a guide for a catheter to be inserted. The puncture needle is electrically conductive from its point to its end projecting out of the cannula and is equipped with an electrical connecting piece at the rear end.
