First Claim
1. A system for automatically and accurately dispensing measured doses of eye drop solution into the eye of a user, the system comprising:
- (a) a dispenser housing;
(b) a loop cartridge comprising a plurality of ampoules each containing a dose of eye drop solution, the plurality of ampoules positioned in spaced increments around and through a flexible looped band, the looped band having an interior face and an exterior face, the loop cartridge removably attachable to the dispenser housing, each of the plurality of ampoules positioned in spaced increments around the looped band comprising;
(i) an eye drop solution reservoir comprising a flexible reservoir wall positioned on the interior face of the looped band;
(ii) a dispensing port in fluid communication with the eye drop solution reservoir, the dispensing port positioned on the exterior face of the looped band and comprising a nozzle defining a dispensing aperture; and
(iii) a port cap removably positioned on the dispensing port and sealing closed the dispensing aperture;
(c) a bi-pedal resilient leg support and positioning structure fixed to and supporting the dispenser housing;
(d) a movable electromechanical loop cartridge advancement mechanism positioned within the dispenser housing;
(e) a port cap hook arm fixed within the dispenser housing and oriented to engage and remove the port cap positioned on each dispensing port as the dispensing port is moved into position for dispensing a dose of eye drop solution;
(f) a movable electromechanical ampoule compression mechanism positioned within the dispenser housing; and
(g) electronic control circuitry for operational control of the loop cartridge advancement mechanism and the ampoule compression mechanism.

Abstract
An eyedrop delivery system for the automated dispensing of eyedrop solution from bottles and ampoules. The system includes a battery and electronic control circuitry. A sprocket drive motor directs the advancement of a loop cartridge band containing eyedrop solution ampoules, moving each one at a time into position for dispensing. A motor rotates a cam to strike a push rod to compress each ampoule. The system includes an eyelid retracting leg assembly. The cartridge automatically advances the next full ampoule into position for dispensing and pushes the ampoule tip aside. The system helps assure that: (1) a known number of drops are dispensed; (2) the dispensed eyedrop(s) fall on the eyeball (by providing eyelid retracting legs to keep the eye open); and (3) the eyedrop(s) landing on the surface of the eye are confirmed using a drop dispensing sensor pair and a surface of the eye sensor pair.

11. A system for automatically and accurately dispensing measured doses of eye drop solution into the eye of a user, the system comprising:
-
(a) a dispenser housing; (b) a loop cartridge comprising a plurality of ampoules each containing a dose of eye drop solution, the plurality of ampoules positioned in spaced increments around and through a flexible looped band, the loop cartridge removably attachable to the dispenser housing; (c) a bi-pedal resilient leg support and positioning structure fixed to and supporting the dispenser housing, the bi-pedal resilient leg support and positioning structure comprising; (i) a U-shaped frame of semi-rigid plastic material defining a central opening through which a quantity of eye drop solution is dispensed, the U-shaped frame comprising first and second legs extending from a middle portion defining the central opening, the middle portion attached to the dispenser housing; (ii) first and second J-shaped feet sections extending from the first and second legs of the U-shaped frame respectively, the J-shaped feet sections extending in a direction back along the legs of the U-shaped frame and spaced therefrom, before curving outward and apart at terminal ends thereof, each leg of the U-shaped frame in combination with one of the J-shaped feet sections, forming a spring compressible by the user to move the terminal ends of the J-shaped feet towards each other, the spring thereafter preferencing the J-shaped feet sections apart; and (iii) cushion pads positioned on the first and second J-shaped feet sections on the outward surfaces of the curved terminal ends thereof; (d) a movable electromechanical loop cartridge advancement mechanism positioned within the dispenser housing; (e) a movable electromechanical ampoule compression mechanism positioned within the dispenser housing; and (f) electronic control circuitry for operational control of the loop cartridge advancement mechanism and the ampoule compression mechanism; wherein when the bi-pedal resilient leg support and positioning structure is compressed by the user and the cushion pads engage the orbital ridge of the user, spring preferencing of the J-shaped feet sections facilitates an open condition of the eyelid.
