sterile lubricant dispenser for dispensing calibrated amount of a sterile lubricant having a viscosity greater than that of 150 P. ## Claims ### Claim 1 A sterile lubricant dispensing system comprised of: a sterile lubricant container containing a quantity of sterile lubricant, wherein said sterile lubricant container has a sterile threaded opening; a compression tool assembly which provides pressure to said sterile lubricant container; and a dispenser to which said sterile threaded opening is selectively affixed, including: a housing containing a sterile threaded channel, wherein said sterile threaded opening is centered within said compression tool assembly such that a longitudinal axis of said sterile lubricant container is on a plane perpendicular to said housing, said housing having an upper housing portion and a lower housing portion, wherein said upper housing portion includes an upper surface that includes a convexly curved section, a sloped section, and a lower flattened horizontal surface section located under the convexly curved and sloped sections, wherein said lower flattened horizontal surface section has a sanitary clearance distance having a value X, wherein said lower housing portion includes a contoured front portion having a sanitary clearance curvature, a base of said lower housing portion extends beyond said lower flattened horizontal surface section, and a height of said lower housing portion as measured between said lower flattened horizontal surface section and a base of lower housing portion is greater than a height of said upper housing portion as measured between said upper surface and said lower flattened horizontal surface section, a refill port assembly having a closed structure with sterile and non-sterile surfaces adapted to receive said sterile threaded opening of said sterile lubricant container, wherein said sterile threaded channel is located within said refill port assembly such that a portion of said refill port assembly is removable to permit reception of said sterile threaded opening within said sterile threaded channel, a refill chamber assembly with a rounded outer chamber housing which encases an inner pressurized chamber cavity, an inner spring, a spring loaded piston, and at least one O-ring, a motion sensor which triggers operation of a magnetic solenoid pin, wherein a center point of said motion sensor is located a distance having a value no greater than 35 percent of X as measured from an outer point (Q) of said lower flattened horizontal surface section, a solenoid valve which activates the opening of a dispensing orifice, a dispensing tube. ### Claim 2 (depends on 1) The sterile lubricant dispensing system of claim 1, wherein said refill port assembly further includes a non-sterile access door. ### Claim 3 (depends on 2) The sterile lubricant dispensing system of claim 2 wherein said non-sterile access door encloses a cavity that accommodates said refill port cap. ### Claim 4 (depends on 3) The sterile lubricant dispensing system of claim 3 wherein said refill port cap includes a non-sterile outer surface, a sterile inner surface, and said sterile threaded channel that interfaces with a one way valve. ### Claim 5 (depends on 1) The sterile lubricant dispensing system of claim 1 wherein said dispenser further includes a sealing aperture door. ### Claim 6 (depends on 5) The sterile lubricant dispensing system of claim 5 wherein said sealing aperture door closes a sterile lubricant aperture. ### Claim 7 (depends on 1) The sterile lubricant dispensing system of claim 1 wherein said compression tool includes a rotatable lever attached to at least one base. ### Claim 8 (depends on 7) The sterile lubricant dispensing system of claim 7 wherein said compression tool further comprises at least one roller attached to said at least one base. ### Claim 9 (depends on 1) The sterile lubricant dispensing system of claim 1 wherein said dispenser further includes a power assembly. ### Claim 10 (depends on 9) The sterile lubricant dispensing system of claim 9 wherein said power supply assembly includes a battery, a charging circuit for recharging, and a connector component which interfaces with said solenoid valve. ### Claim 11 (depends on 1) The sterile lubricant dispensing system of claim 1 wherein said dispenser further includes an electrical adapter positioned at a base of said vertical rear portion. ### Claim 12 (depends on 1) The sterile lubricant dispensing system of claim 1 wherein said sterile lubricant container is tube-shaped. ### Claim 13 (depends on 1) The sterile lubricant dispensing system of claim 1 wherein said dispenser further includes at least one grip attached to said lower portion. ### Claim 14 (depends on 1) The sterile lubricant dispensing system of claim 1 wherein said dispenser further includes a catch basin positioned in said lower portion. ### Claim 15 (depends on 1) The sterile lubricant dispensing system of claim 1 wherein said dispenser further includes an exaggerated concave contour positioned in said contoured front portion. ### Claim 16 (depends on 1) The sterile lubricant dispensing system of claim 1 wherein a distance from a center of said sterile lubricant dispensing aperture and a tangency point of said lower horizontal surface member is no less than 100 mm. ### Claim 17 (depends on 16) The sterile lubricant dispensing system of claim 16 wherein the radius of the curve of said contoured front is less at that lower points of contoured front portion than higher points.
