Abstract
An injection system applicable to off-the-shelf syringes having a microneedle hub may reduce dead space and isolate the drug fluid from the microneedle chip to avoid compatibility issues. An insert may be disposed inside a male luer fitting and extend so that it is also disposed inside the female luer fitting using an insert. A septum may isolate the drug fluid from the microneedle chip in the hub prior to activation and the septum may, after activation, seal the triangular space in the hub to prevent leakage of fluid back to the syringe.
