operation from this product.

Components of the Welch Allyn DuraShock Integrated
Aneroid Sphygmomanometer

Gear-free Gauge

Snaps into Cuff

Valve

Integrated One­Piece Cuff

Tubing

Assembly Instructions

1. Attach the gauge to the cuff by pressing the gauge
stem into the cuff port until you feel it engage. The
gauge can be rotated 360° in the cuff port to improve
your view of the dial face during readings.

2. Push the remaining smaller-diameter barb of the valve
onto the tube.

NOTE: To assemble the bumper to a Welch Allyn
DuraShock integrated gauge (model DS44 only), gently slide
bumper over the gauge until the bumper just contacts the
crystal around the entire circumference. Do not force to the
point where the bumper shape is deformed, as this will
reduce the shock-resistant properties of the bumper.
Properly assembled, about 1/16-inch (2 mm) of the gauge
will be visible below the bumper when viewed from the
side (see illustration).

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 “Artery 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 artery index marker 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.

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.

WARNING: If luer lock connectors are used in the construction
of tubing, there is a possibility that they might be inadvertently
connected to intravascular fluid systems, allowing air to be
pumped into a blood vessel.

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.

Specifications and Standards

The Welch Allyn DuraShock integrated aneroid sphygmomanometer is accurate to
±3 mm Hg and conforms to applicable sections of the following standards for aneroid
sphygmomanometers:

• American National Standard ANSI/AAMI SP9-1994, Non-automated sphyg-

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
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.

using a Y-connector

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 315-685-4560.

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 of alcohol pad.

Integrated One-Piece Cuff: Cuffs may be safely cleaned with a damp cloth (70%
alcohol or 0.5% bleach solution may be used) or wash in warm water (140° F, 60° C
maximum) with mild detergent. Before laundering the cuff:

1. Remove the inflation bulb and valve.

2. Close off the end of the tubing with Tube Plug Accessory (part no. 5082-163).

3. Close off the cuff port with Cuff Port Laundering Plug (part no. 5082-250).

4. Place the hook and loop fasteners in the closed position.

5. Machine launder using gentle cycle, warm water, and mild detergent.

6. Air dry completely and reassemble components.

DO NOT PRESS WITH HOT IRON.

Disinfecting

Glutaraldehyde-type liquid disinfectants may be used on the durable one-piece cuff.
Follow instructions for use provided with the Glutaraldehyde product. Prolonged use of
these disinfectants may cause discoloration. Do not
disinfectants on the aneroid gauge, bulb, valve, or gladder.

use glutaraldehyde-type liquid

Sterilizing

The durable integrated blood pressure cuff may be gas sterilized. Do not use steam or
heat to sterilize the cuff, bulb, valve, or bladder. Do not
gauge.
