The method includes automatically injecting an injectable into a surface in contact with the needle-free injector in response to a skin compression parameter of an end of the needle-free injector. A 112'-110 needle-free injector device (102) includes predefmed structures formed on it to inject an injectable through a non-porous material. The predefmed Nu) structures engage an airlock mechanism such that an airlock in the non- porous material and operably coupled to the airlock mechanism can on- ly be opened and closed to enable needle-free injection through the non- porous material without disrupting an integrity of the non-porous materi- al by the needle-free injector device. Other functions, embodiments and methods for using and programming the needle-free injector device are FIG. IA also provided.
