USPTO Abstract
A microdispensing ophthalmic pump is provided for repeatedly delivering doses as small as 5 microliters within an angular operating range. The pump basically comprises a reservoir (12), a dispensing cap (18), an actuator (20) and a pump body (14) with a pump mechanism (16) disposed therein. The pump mechanism (16) is regulated by a limited-travel inlet check valve and a biased-closed outlet check valve. A failsafe mechanism is formed between the actuator (20) and dispensing cap (18) to prevent operation of the pump outside the operating range. <IMAGE>
