Inflation System Change and Replacement
The Welch Allyn DuraShock integrated blood pressure gauge connects effortlessly to
the inflation system via a unique port connection. Therefore, only Welch Allyn
integrated blood pressure cuffs can be used with the Welch Allyn DuraShock
integrated blood pressure gauge.
1. To remove the inflation system, simply grasp the
gauge and pull away from the cuff. Rotating the
gauge as it is being pulled away from the cuff will
make removal easier.
2. To attach a new or different size blood pressure
cuff, simply press the gauge stem into the cuff port
until you feel it engage. Rotating the gauge as it is
being pressed into the cuff will make insertion
easier.

momanometers.
• European Standard EN 1060-1: 1996, Non-invasive sphygmomanometers,
Part 1: General Requirements
• European Standard EN 1060-2: 1996, Part 2: Supplementary requirements
for mechanical sphygmomanometers (excluding Section 7.4.3 for pointer
thickness).
• INMETRO Technical Metrological Regulation Number 24 of February 26,
1996 (excluding Section 5.4 for pointer thickness).
This product will maintain the safety and performance characteristics specified at
temperatures ranging from 0°C (32°F) to 46°C (115°F) at a relative humidity level not
to exceed 85%.
Calibration Check of Aneroid Sphygmomanometer
Welch Allyn recommends that the calibration of aneroid sphygmomanometers be
checked using the following procedure on an annual basis.
1. Connect gauge to a high-quality, known pressure standard
1
using a Y-connector
and the DuraShock Caliberation Connector accessor (part no. 5082-255).
2. Pressurize gauge to slightly above 300 mm Hg.
3. Bleed pressure down no faster than 10 mm Hg per second, stopping to check the
pressure at 300, 250, 200, 150, 60 and 0 mm Hg.
