Our modular design allows the quick changeover of the two main drug handling components. The Numnuts® Spares Kit contains all the spare hardware you might need to keep your Numnuts device working smoothly, including: two spare fluid junctions, the clear part the NumOcaine bottle connects to; an additional dual-stage injector, the part you push to inject; and three extra trays of needles. Numnuts® (in conjunction with NumOcaine™) enables sheep producers to mitigate pain in their lambs during castration and tail-docking. Numnuts® puts fast, targeted and safe application of local anaesthetic into the hands of farmers & contractors at marking time. The combination of rubber ring and local anaesthetic applicator in a single device enables Numnuts to target acute pain where it occurs, within minutes.
