ADC's revolutionary new DuraShock gearless manometer from ADC & Welch Allyn. The DuraShock Adult BP is an Integrated Aneroid Sphygmomanometer featuring gear-free, helix-spring technology. The shock-resistant aneroid sphygmomanometer has a gauge that snaps directly into the blood pressure cuff via a patented cuff port. This system enables the gauge to rotate 360° for easy viewing and facilitates quick cuff changes. The left- or right-arm design accommodates artery-maker placement over the brachial artery on either arm.
