Noninvasive ankle brachial pressure index measurement unit

This category includes automated, portable electronic devices that calculate the ankle brachial pressure index (ABPI) to aid in diagnosing peripheral vascular disease. They function by simultaneously measuring blood pressure oscillations in the arm and ankle using inflatable cuffs and integrated pressure transducers. These units are typically battery-powered and designed for use by healthcare professionals in clinical or point-of-care settings.

These devices are classified as active medical devices that provide diagnostic information without penetrating the body. They are supplied through standard medical equipment distribution channels and require calibration and maintenance according to manufacturer guidelines. Operation relies on oscillometric technology to detect vascular pressure fluctuations and compute the index ratio automatically.
