Manual aneroid hand gauge sphygmomanometer with thumbscrew valve
Description
The Welch Allyn Hand Gauge Sphygmomanometer – Double Tube with Thumbscrew Valve (DS-5602-189) is a manual, aneroid blood pressure device featuring gear-free DuraShock technology for long-lasting accuracy. Designed as a double-tube hand gauge manometer with a traditional thumbscrew air release valve, it is supplied with an adult one-piece Velcro cuff and zipper case. The soft, ergonomic hand gauge with jewel movement and laser-engraved dial delivers reliable, precise readings, while its shock-resistant construction helps maintain calibration even after accidental drops, supporting a lower lifetime cost of ownership in clinical practice.
Bnefits
Gear-free DuraShock technology helps maintain calibration longer than traditional geared aneroid gauges
Shock resistant design can withstand drops of up to approximately 30 inches and remain in calibration, reducing lifetime costs
Double-tube hand gauge configuration for use with compatible two-tube cuffs and inflation systems
Traditional thumbscrew valve allows controlled, precise air release during blood pressure measurement
Soft, comfort grip hand gauge enhances clinician comfort during repeated use
Jewel movement provides smooth operation and long service life
Laser-engraved dial face supports accurate, easy-to-read measurements
Supplied with an adult one-piece Velcro cuff and zipper case for convenient storage and transport
Part of the Welch Allyn DuraShock Gold/Silver series of aneroid sphygmomanometers, designed for high reliability in demanding clinical environments

Usage
Before first use, familiarise yourself with the instructions for use supplied by Welch Allyn and any local clinical protocols for blood pressure measurement.
Inspect the gauge, cuff, tubing and bulb for visible damage, leaks or wear; do not use the device if any components appear damaged.
Select the appropriate cuff size for the patient’s arm according to the sizing marks on the cuff; using the wrong size may lead to inaccurate readings.
Wrap the cuff snugly around the patient’s upper arm at heart level, ensuring the artery marker on the cuff is aligned with the brachial artery.
Attach the double tubes to the hand gauge and inflation bulb assembly (if not already connected) and ensure all connections are secure.
Place the stethoscope over the brachial artery distal to the cuff edge, following standard auscultatory technique.
Close the thumbscrew valve and use the inflation bulb to inflate the cuff to the target pressure above the expected systolic level.
Slowly open the thumbscrew valve to release air at a controlled rate (typically 2–3 mmHg per second) while listening for Korotkoff sounds and observing the gauge.
Note the gauge reading at the appearance (systolic) and disappearance (diastolic) of Korotkoff sounds, according to your clinical protocol.
Fully deflate the cuff, remove it from the patient, and record the measurement in the patient’s notes.
After use, wipe the cuff, gauge and bulb surfaces with an approved disinfectant compatible with the device materials, in accordance with local infection-control policies and the manufacturer’s recommendations.
Store the device in its protective case in a clean, dry environment when not in use, and arrange periodic calibration checks as required by local quality and maintenance standards.
Contraindications
Do not apply the cuff to limbs with intravenous infusions, shunts, severe injury, or compromised blood flow unless expressly directed by a clinician and according to local protocols.
Avoid use on patients with severe clotting disorders or those at high risk of bruising without specialist guidance.
Do not use if the device is visibly damaged, leaking, or fails calibration checks.
Not intended for invasive blood pressure monitoring or for use as a life-supporting or life-sustaining device.
Adverse Effects
Temporary discomfort, tingling or numbness in the limb due to cuff inflation.
Potential for minor bruising or petechiae, particularly in patients with fragile vessels or clotting abnormalities.
Prolonged or excessive inflation may cause pain or circulatory compromise; follow recommended inflation times and pressures.
Risk of cross-contamination if the cuff and device are not cleaned and disinfected appropriately between patients.
Storage Conditions
Store in a clean, dry area away from dust, moisture and direct sunlight.
Avoid exposure to extreme temperatures or humidity that may affect the gauge mechanism or cuff materials.
Keep the device in its protective zipper case when not in use to minimise mechanical shock and contamination.
Do not place heavy objects on top of the device or subject it to unnecessary impact or dropping.
Duration
Not applicable; this is a reusable diagnostic instrument used for the duration of individual blood pressure measurements and retained in service subject to routine maintenance and calibration.
Onset
Immediate; accurate pressure readings are available as soon as the cuff is inflated and the gauge is used according to standard auscultatory blood pressure measurement technique.
