Designed as a visual reminder for healthcare workers, the label features a seventy-two-hour elapsed time indicator adhered to an orange 8.5L x 2.5W In. self-looping hangtime label, allowing for quick and ongoing observable identification of how long it has been since an endoscope was reprocessed. The label allows staff to document critical information including the scope serial number and healthcare worker initials, as well as the date and time the indicator was activated. No preconditioning is required, there are no moving parts, and there is no power source. To activate the indicator, firmly press the blister on the strip, and upon activation, a safe dye migrates along a seventy-two-hour display run-out window, showing elapsed time. Accurate to within +/- 10%. The 72 hour indicator joins similar Healthmark Industries offerings, including the 1 Hour, 7 Day & 12 Day Indicator Hangtime Labels: “HTK-1H2” (One Hour Indicator), “HTK-7D2” (7 Day Indicator) & “HTK-12D” (12 Day Indicator). The 72 Hour Indicator Hangtime Label is available for purchase in a quantity of one hundred.
