device includes a visually observable detector for furnishing
evidence of the exposure of the device to a disinfection
solution. See, e.g., the "Summary of the Invention" section
at pages 3 and 4 of the specification. An understanding of
the invention can be derived from a reading of exemplary claim
18, which is reproduced below.
18. A device for indicating residence time
in a liquid disinfection solution, the device
comprising a visually observable detector of
exposure of the device to said solution, said
device being selected such that upon exposure of
the device to said solution said detector
visibly changes after a predetermined time
interval, the detector comprising a first
visually apparent material that is water soluble
and crosslinkable by a crosslinking component
contained in said liquid disinfection solution,
and a second visually apparent material that is
soluble in said liquid disinfection solution, so
that upon immersion of the device, the first
material crosslinks to an insoluble state such
that the first material, remains visually
apparent in said device and the second material
is dissolved in a visually apparent manner.
No prior art references of record are relied upon by the
