The patented dual stage injector prevents ‘premature injectuculation’ . The mechanism will only dispense the NumOcaine once the needle is forward and in the animal at the required angle and depth, defined by the Numnuts device. If the needle comes up against a blockage (dag, stone ot bone in the tail), the dual stage injector provides feedback to the operator to readjust their position and does not waste a dose of NumOcaine on outside of the animal.

Changing the fluid junction each season ensures the NumOcaine being injected into your new-born lambs is passing through clean apparatus. O-ring degrade with UV. A combined Oring & fluid junction replacement ensures ‘sticky free’ injections for thousands of cycles.

Regular needle changeover ensures a sharp needle, reducing the pain of injection and keeping injection loads low for the operator.
Reduce injection or cross contamination of bugs by regularly changing over needle.
