Briefly, an injection delivery system is described for subcutaneous or intramuscular injection of a drug, in particular a large volume of a biologic drug, high and low viscosity biologies, or a large volume of a high viscosity and low viscosity chemical drug. The injections may be self-administered or performed by a caregiver. The system uses a pump to move a drug from a vial, thorough an infusion set, and into the patient. A vial of a biological or chemical drug is set into a vial adapter that is associated with the pump, which can be manual or powered. A fluidics subassembly connects the vial adapter, pump, and the infusion set so that a drug pathway is enabled from the vial to the patient. The fluidics subassembly has one or more check valves to assure that the drug pathway is only enabled for a one-way drug flow out of the vial and to the patient. The infusion set has flexible tubing that connects the fluidics subassembly to cannula assembly inside an infuser housing. The cannula assembly has an air evacuation assembly near the tip of the needle. This air evacuation assembly is constructed to safely exhaust air from the cannula assembly at three times: (1) at initial setup to exhaust air while the drug is filling the cannula assembly, which enables the self-priming; (2) during injection to exhaust drug-entrapped air, which increases injection safety; and (3) at the end of drug delivery to exhaust air after the full dose of drug has been delivered to the cannula assembly, including drug that was in the tubing, which reduces wasted drug and minimizes the amount of drug overfill required in the vial.
