K213431 is an FDA 510(k) clearance for the Handheld Pulse Oximeter. Classified as Oximeter (product code DQA), Class II - Special Controls.

Submitted by Shenzhen Witleaf Medical Electronics Co., Ltd. (Shenzhen, CN). The FDA issued a Cleared decision on February 26, 2023 after a review of 493 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Anesthesiology FDA review panel, regulated under 21 CFR 870.2700 - the FDA anesthesiology and respiratory 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 Anesthesiology submissions.
