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
use glutaraldehyde-type liquid
disinfectants on the aneroid gauge, bulb, valve, or gladder.
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
attempt to sterilize the aneroid
gauge.
