K023956 is an FDA 510(k) clearance for the THERMOMETER MODELS ST313C/F, ST314C/F, ST323C/F, ST324C/F, ST333C/F, ST334C/F. Classified as Continuous Measurement Thermometer (product code FLL), Class II - Special Controls.

Submitted by Mesure Technology Co., Ltd. (San Chung City, TW). The FDA issued a Cleared decision on June 17, 2004 after a review of 568 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.
