sphygmomanometer technology. We expect you will receive years of trouble free
operation from this product.
Components of the Welch Allyn DuraShock
Aneroid Sphygmomanometer with Integrated
Gauge Adapter
Assembly Instructions
1. Snap the gauge into the adapter (Figure 1).
2. Slide the clip on the back of the gauge through the cuff loop (Figure 2).
3. Press the clip into the locked position (Figure 3).
4. Attach the shorter hose from the cuff to the stem at the bottom of the adapter.
Operating Instructions
Auscultatory Method
1. Select cuff size appropriate for the patient’s arm circumference. The applicable
range, in centimeters, is printed on each cuff.
Note: The “Index Marker” on the cuff should fall within the “Range” indicated
on the cuff. If the index marker falls short of range, a larger cuff should be used
to ensure accurate results. If the index marker is past the range, a smaller cuff
should be used to ensure accurate results.
2. Wrap the cuff around the arm with the Arteria (artery) located over the brachial
artery and with the lower edge of the cuff 1-inch (2.5 cm) above the bend in the
elbow.
3. Inflate cuff rapidly to a level 30 mm Hg above estimated (or palpatory) systolic
pressure.
4. Partially open the valve to allow deflation at a rate of 2 to 3 mm Hg per second.
5. As the pressure falls, note systolic pressure and diastolic pressure with your
stethoscope.
6. Rapidly release the remaining pressure and record measurements
immediately. After a minimum of 30 seconds, repeat the above steps for a
second reading.
Inflation System Change and Replacement
1. To remove the inflation system, disengage the clip on the back of the inte-
grated gauge adapter and slide the gauge off the cuff loop. Pull the short tube
off the adapter stem.
2. To install the new cuff, follow steps two, three, and four of the Assembly
Instructions.
Specifications and Standards
The Welch Allyn DuraShock aneroid sphygmomanometer with Integrated Gauge Adapter
is accurate to ±3 mm Hg and conforms to applicable sections of the following standards
for aneroid sphygmomanometers:
• American National Standard ANSI/AAMI SP10-2003, Non-automated
sphygmomanometers.
• European Standard EN 1060-1: 1996, Non-invasive sphygmomanometers,
Part 1: General Requirements
• European Standard EN 1060-2: 1996, Part 2: Supplementary require-
ments 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-connec-
tor.
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.
NOTE: Your ability to measure the accuracy of a gauge depends upon the sensitivity of the
pressure standard you use for the calibration procedure.
• If using a manometer (mercury column or aneroid gauge) rated at
±3.0 mm Hg, you will be able to determine the accuracy of the gauge
being tested to within ±6.0 mm Hg.
• If using a device (e.g., digital pressure standard) rated at ±0.1 mm Hg,
you will be able to determine the accuracy of the gauge being tested to
within ±3.1 mm Hg.
1 Welch Allyn recommends using as sensitive as possible a pressure standard when
performing calibration checks. A Setra Pressure Meter (part no. 2270-01), which is
calibrated for ±0.1 mm Hg, or Netech (part no. 200-2000IN), which is calibrated for ±1.0
mm Hg, work well for this application. Both meters can be purchased from Welch Allyn by
calling 828-684-4895.
How to Clean, Disinfect, and Sterilize the Welch
Allyn DuraShock Sphygmomanometer
Cleaning
Aneroid Gauge, Inflation Bulb, and Valve: Clean the aneroid gauge, inflation bulb, and
valve by wiping with slightly dampened cloth or alcohol pad.
Two-Piece Cuff and Bladder: Safely clean the cuffs with a damp cloth or wash in
warm water (140° F, 60° C maximum) with mild detergent.
Before laundering the cuff:
1. Remove the bladder, inflation bulb and valve.
2. Place the hook and loop fasteners in the closed position.
3. Machine launder using gentle cycle, warm water, and mild detergent.
4. Air dry completely and reassemble components.
DO NOT PRESS WITH HOT IRON.
Disinfection
To disinfect the two-piece cuff, use Gluataraldehyde-type liquid disinfectants. Follow
instructions for use provided with the Glutaraldehyde product. Prolonged use of these
disinfectants may cause discoloration. Do not use glutaraldehyde-type liquid disinfectants
on the aneroid gauge, bulb, valve, or bladder.
Sterilization
Gas sterilization is acceptable for the two-piece blood pressure cuff. Do not use steam or
heat to sterilize the cuff, bulb, valve, or bladder. Do not attempt to sterilize the aneroid
gauge.
CAUTION: Do not allow a blood pressure cuff to remain on
patient for more than 10 minutes when inflated above 10 mm
Hg. This may cause patient distress, disturb blood circulation,
and contribute to the injury of peripheral nerves.
