Ophthalmic dispensing device

A manually operated dispensing device for dispensing an ophthalmic solution, the device being adapted to deliver the ophthalmic solution to a surface of an eye in a desired spray pattern with an impact pressure on the eye that is comfortably tolerated by an individual, the device comprising:

• a container having a neck defining an opening;
• a pressurized gas capable of being contained within the container;
• collapsible pouch configured to be contained within the container;
• an ophthalmic solution contained within the pouch;
• a mounting cup configured to operably engage the pouch so as to seal the ophthalmic solution therein, the mounting cup being further configured to sealingly engage the neck so as to retain the pouch within the container and to seal the pressurized gas between the container and the pouch such that the pressure of the pressurized gas is exerted on the pouch;
• a valve operably engaged with the mounting cup and configured to be capable of releasing a flow of the ophthalmic solution from the pouch, the flow through the valve being generated by the pressure exerted on the pouch;
• a nozzle member in communication with the valve and configured to receive the flow and direct the flow of the ophthalmic solution therefrom in a selected spray pattern;
• and
• an actuator operably engaged between the valve and the nozzle member for actuating the valve so as to initiate the flow from the valve through the nozzle member, the actuator being further configured to allow selective deactuation of the valve, so as to thereby selectively stop the flow of the ophthalmic solution through the nozzle member, after the valve has been actuated by the actuator.
