Abstract: A needle hub assembly for a pen needle includes a needle hub, a cannula or needle coupled to the needle hub, a retractable and compressible sleeve covering at least one end of the cannula, and an outer cover. The outer cover encloses the needle hub and the retractable sleeve. The retractable sleeve is coupled to the hub to cover the end of the cannula where the sleeve can pass through or can be pierced by the cannula and the sleeve retracts axially on the cannula. The sleeve is resilient and returns to an original configuration when an insertion force is released. The needle hub can have a first sleeve to cover a patient end of the cannula, and second sleeve to cover a non-patient end of the cannula where the sleeves retract onto the cannula or hub and expand to the original configuration to cover the ends of the cannula.
