Abstract
An injection guide globally aligns an injector to an angle selected for consistent subcutaneous delivery of an injectate, while locally aligning a patient's skin normal to the injection path at the location where the injection pierces the skin. This arrangement advantageously maintains controlled contact between an injector and a subject's skin in order to deliver the full, intended volume of injectate into the patient's subcutaneous layer while avoiding misdelivery into adjacent layers such as the patient's dermis or muscle.
