Lafayette Instrument Company patented standard blood pressure Kovacic-style cuff for LX5000-S and LX4000-S computerized polygraphs eliminates problems associated with a loosely wrapped cuff and ensures that the cuff does not shift away from the brachial artery during application. In addition, the center of the bladder is clearly marked on the inner and outer surface of the cuff for correct application on either right or left limb. The unique Velcro tab and cuff aperture technique provides a tight “double wrap”.
