Abstract
The present disclosure is directed to devices that administer single or multiple doses of one or more substances to the eye, nose, or ear of a user. The precise and repeatable dosing features of the presently disclosed devices overcome many of the disadvantages associated with known methods for dispensing substances to, for example, the eye of a user. The devices administer precise doses of a substance to a precise location from ampoules that may be single-dose or two-dose ampoules, which may be externally or internally pierced.
