The Panasonic EW3901S Large Cuff is a specialized, medical-grade replacement accessory engineered strictly for users requiring an expanded arm diameter for blood pressure tracking. Sold exclusively as a standalone cuff, it allows households to share a single digital monitor base across individuals of different physical builds, ensuring accurate, pinch-free systolic and diastolic readings without requiring the purchase of an entirely new diagnostic machine.

Precision Sizing & Compliance

Expanded Large Diameter: Explicitly tailored to accommodate larger upper arm sizes ranging from 13-3/4" to 17-1/3" (35 cm to 44 cm). Utilizing a properly sized cuff is clinically critical, as using a cuff that is too small can artificially elevate blood pressure readings.

Broad Panasonic Compatibility: Fully approved and calibrated to plug directly into a wide lineup of Panasonic digital upper arm monitors, including the following specific consumer models:

EW-BU35W, EW-BU04W, and EW3122S

EW3109W, EW3109ACW, and EW3106W

Ergonomics & Application

360-Degree Rotating Tubing: Built with an integrated air tube connector that rotates a full 360 degrees. This spatial flexibility prevents the rubber air hose from kinking, twisting, or pulling uncomfortably during inflation cycles.

Ambidextrous Design Framework: The contoured structure makes self-application completely effortless. It is balanced for easy fastening and alignment using a heavy-duty hook-and-loop system, accommodating both left-handed and right-handed operators seamlessly.
