Welch Allyn DuraShock DS55 Hand Aneroid Sphygmomanometer - Silver Series DS-5501-189 Black

The Welch Allyn DuraShock DS55 Hand Aneroid Sphygmomanometer, part of the Silver Series, is a professional-grade device engineered for non-invasive blood pressure measurement in adult and pediatric patients. This manual upper arm blood pressure monitor is designed for use in clinics and medical practices, providing accurate and reliable readings in professional healthcare environments. It incorporates DuraShock™ technology, featuring a gearless manometer for enhanced durability and consistent performance.

The DS55 model, identified as DS-5501-189, is built with a shock-resistant design that has been validated to stringent AAMI standards. This technology allows the sphygmomanometer to withstand drops up to 76cm onto a solid surface while maintaining calibration accuracy, thereby reducing long-term maintenance costs. Its laser-engraved dial ensures maximum precision and readability for healthcare professionals.

This "Black" sphygmomanometer features a traditional thumbscrew-style air release valve for controlled pressure deflation. For patient safety, the device is not made with natural rubber latex. Its portable design, complemented by a zippered carrying case, facilitates seamless use across diverse clinical settings.

1. Wrap the cuff around the patient’s upper arm, ensuring a snug fit.
2. Position the stethoscope diaphragm over the brachial artery.
3. Inflate the cuff using the inflation bulb until circulation is momentarily restricted.
4. Gradually release the air via the precision valve while auscultating the Korotkoff sounds.
5. Record systolic and diastolic readings as indicated on the aneroid dial.

• Ensure proper cuff sizing for accurate measurements.
• Avoid over-inflation to prevent patient discomfort.
• Store in a dry, dust-free environment to maintain gauge precision.
• Regularly calibrate to uphold measurement accuracy.
