Title:
HYDRODYNAMICALLY ACTUATED PRESERVATIVE FREE DISPENSING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/212033
Kind Code:
A8
Abstract:
Multi-dose preservative-free ocular fluid delivery devices are provided. The fluid delivery device includes a fluid dispensing system and a fluid package for storing a liquid therein and supplying said liquid to the dispensing system. The dispensing system comprises an elongated chamber which includes a check valve which defines a frontal closure to the chamber. The valve is normally closed and hermetically seals the chamber. The dispenser includes a vibration motor that induces oscillations to the chamber and to the fluid within. The oscillations of the chamber impart momentum to the fluid stored in the chamber which in turn imparts force that cyclically opens the valve to dispense streams or liquid droplets. Fluid is dispensed only when the motor oscillates while otherwise the valve is hermetically closed.
