Components of the Welch Allyn DuraShock Integrated Aneroid Sphygmomanometer

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 degree 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 patients 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.

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.

  • 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.
  • 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 sphygmomanometers.
  • 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? (32?) to 46? (115?) at a relative humidity level not to exceed 85%.

How to Clean, Disinfect, and Sterilize the Welch Allyn DuraShock Sphygmomanometer


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?, 60? maximum) with mild detergent. Before laundering the cuff:

  • Remove the inflation bulb and valve.
  • Close off the end of the tubing with Tube Plug Accessory (part no. 5082-163).
  • Close off the cuff port with Cuff Port Laundering Plug (part no. 5082-250).
  • Place the hook and loop fasteners in the closed position.
  • Machine launder using gentle cycle, warm water, and mild detergent.
  • Air dry completely and reassemble components.



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.


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.
