K201600 is an FDA 510(k) clearance for the Infrared thermometer, models KFT-22M, KFT-22, KFT-23, KFT-24, KFT-25, KFT-26,.... Classified as Continuous Measurement Thermometer (product code FLL), Class II - Special Controls.

Submitted by Kangfu Medical Equipment Factory (Wenzhou, CN). The FDA issued a Cleared decision on December 10, 2021 after a review of 546 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the General Hospital FDA review panel, regulated under 21 CFR 880.2910 - the FDA general hospital device framework. The Traditional 510(k) pathway establishes clearance through substantial equivalence to a legally marketed predicate device, without requiring clinical trial data.

Device pattern: High-complexity regulatory submission. Elevated predicate reliance profile. The extended review timeline suggests the FDA required additional documentation before confirming substantial equivalence - a pattern common in complex or first-of-kind General Hospital submissions.
