K803260 is an FDA 510(k) clearance for the SENSOMAT MUSCLE/TISSUE PH. Classified as Analyzer, Ion, Hydrogen-ion (ph), Blood-phase, Indwelling (product code CBZ), Class II - Special Controls.

Submitted by Biochem International, Inc. (Mchenry, US). The FDA issued a Cleared decision on February 2, 1981 after a review of 40 days - a notably fast clearance cycle.

This device falls under the Anesthesiology FDA review panel, regulated under 21 CFR 868.1170 - 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: Fast-track predicate clearance. Standard predicate reliance. The short review cycle indicates strong predicate alignment - the FDA found sufficient equivalence without extended technical review.
