Abstract:
1. An anaesthetic drug delivery device comprising: a. a needle assembly including a needle having a proximal end and a distal end, a central bore extending between the proximal end and the distal end, said distal end having a sharp distal tip, and the needle assembly further comprising a needle hub including a distal portion connected to the proximal end of the needle; b. a releasable catheter lock having a locked position and an unlocked position, attached to and extending proximally from a proximal portion of the needle hub, the catheter lock including a central bore extending the entire length of the catheter lock; and c. a catheter having a portion pre-loaded through the central bore of the needle or needle hub and including a proximal end, a distal end, a central bore along the entire length of the catheter and an electrical conductor extending from the proximal end to the distal end of the catheter to an electrically conductive distal tip of the catheter, the distal end of the catheter being disposed in the central bore of the catheter lock and extending into the needle hub; wherein the catheter lock releasably holds the catheter in a position within the central bore of the catheter lock such that the electrically conductive distal tip of the catheter is in electrical contact with an inner surface of the needle.
