The Welch Allyn sphygmomanometer with gearless, shock-resistant DuraShock technology offers enormous practical advantages over traditional sphygmomanometers. Especially appreciated in the fast-paced reality of medical environments where instruments can be handled roughly or dropped. Thanks to DuraShock technology, Welch Allyn sphygmomanometers:
- Maintain calibration longer than traditional gear-driven sphygmomanometers thus ensuring more accurate measurements
- Do not have to be replaced as frequently as traditional models, thus saving costs in the long run.
- They feature the only manometer that complies with the AAMI (Association for the Advancement of Medical ) Instrumentation's impact resistance specification (resistant to being dropped from a height of 76 cm onto a hard surface without affecting calibration).
How DuraShock technology works
In the traditional aneroid sphygmomanometer, several delicate gears and springs convert and amplify the vertical movement of the pinion into rotational movement to rotate the cursor. The gearless DuraShock technology uses a single helical spring to directly convert the vertical movement of the pinion into the rotational movement of the cursor without the need for multi-step gears. By realising a gearless system, Welch Allyn has created a gauge with fewer moving parts, which is shock-resistant and lighter than conventional gauges. Until now, accidentally dropping a sphygmomanometer required recalibration or replacement. DuraShock, on the other hand, can fall from a height of 76 cm onto a hard surface while maintaining its accuracy, and is the only manometer that complies with AAMI's impact resistance specification.
