Abstract
An on-body injector includes a drug reservoir having an outlet. First and second pistons may be positioned within the reservoir, with the second piston first being moved to open the outlet, followed by the first piston being moved to convey a drug from the reservoir via the outlet. The reservoir may instead include a cover, with a valve positioned between the outlet and the cover. The valve is rotated to place a channel of the valve in fluid communication with a through-hole of the cover, allowing flow from the reservoir via the outlet. The reservoir may instead include a valve movable from a condition in which it deforms the outlet, preventing flow through the outlet, to a condition allowing flow. The reservoir may instead include a seal that is deformed by an increase in pressure within the reservoir, with the deformed seal being open to allow flow through the outlet.
