K191639 is an FDA 510(k) clearance for the TK Insulin Syringe with/without Saftey Retractable Device. Classified as Syringe, Antistick (product code MEG), Class II - Special Controls.

Submitted by Anhui Tiankang Medical Technology Co., Ltd. (Tianchang, CN). The FDA issued a Cleared decision on September 11, 2020 after a review of 450 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the General Hospital FDA review panel, regulated under 21 CFR 880.5860 - 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.
