The Welch Allyn sphygmomanometer with gearless, shock-resistant DuraShock technology offers enormous practical advantages over traditional geared sphygmomanometers. These advantages are especially noticeable in the fast-paced world of medical environments, where instruments can be handled roughly or dropped.

Thanks to DuraShock technology, Welch Allyn blood pressure monitors:
- maintain calibration longer than traditional gear-based blood pressure monitors, ensuring more accurate measurements.
- they do not need to be replaced as frequently as traditional gear-based blood pressure monitors, thus saving costs in the long term.
- they are equipped with the only pressure gauge that complies with the shock resistance specification according to the AAMI - Association for the Advancement of Medical Instrumentation - (withstands a fall from a height of 76 cm onto a hard surface without any alteration of the calibration).

In a traditional aneroid sphygmomanometer, multiple delicate gears and springs convert and amplify the pinion's vertical motion into rotational motion to rotate the slider. Gearless DuraShock technology uses a single helical spring to directly convert the pinion's vertical motion into the slider's rotational motion without the aid of multi-step gears.

By designing a gearless system, Welch Allyn created a gauge with fewer moving parts, is shock resistant, and lighter than traditional gauges.

Until now, accidentally dropping your blood pressure monitor required recalibration or replacement.

The DuraShock can be dropped from a height of 76cm onto a hard surface while maintaining its accuracy, and is the only pressure gauge that meets the AAMI shock resistance specification.
