The Disposable V-Lok cuff is part of the Calibrated&trade V-Lok&trade Inflation system for use with manual blood pressure instruments. Each system is latex-free and interchangeable with WA Baum's line of reusable cuffs. The Calibrated V-Lok system clearly indicates whether or not the correct size cuff is being used. The center of the bladder is clearly marked on the inner and outer surfaces of the cuff for correct application on either the right or left limb. This cuff comes with two threaded adapters for connecting tubing to monitoring systems.
