Abstract
A contact lens cleaning device provides a mechanical apparatus for the thorough agitation and cleaning of contact lenses immersed in a disinfecting solution. The device comprises a base portion bearing a reservoir for containing a measured amount of disinfecting solution, and a main housing portion including a lens holder portion for releasable capture of the contact lenses to be cleaned. The lens holder is connected to rotating crankshafts by connecting rods, and the crankshafts are connected to a knob on the outside of the main housing, so that rotary motion of the crankshafts is translated to reciprocating motion of the lens holder.
Claims4
A contact lens cleaning device comprising:
- a housing member bearing an internal cavity for containing a cleaning solution;
- a lens holder portion for releasable capture of said contact lens, said lens holder portion terminating in end portions separated by a first distance, said lens holder portion conditioned for reciprocating motion within said housing member;
- connecting rod means attached to said lens holder portion, said connecting rod means comprising a pair of connecting rods each attached to only one of said lens holder end portions;
- and
- rotary drive means connected to said connecting rod means, said rotary drive means comprising a pair of crankshafts each bearing an off-center crankpin, said crankpins attached to said connecting rods so that said crankpins are separated by a second distance lens than said first distance, so that rotation of said rotary drive means moves said lens holder portion in reciprocating motion.
