Abstract
A sterile lubricant dispenser for dispensing calibrated amount of a sterile lubricant having a viscosity greater than that of 150 P.
Claims17
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.
