Tycos Aneroid Sphygmomanometers

Tycos is Welch Allyn's flagship line of manual blood pressure instruments, built around a single-tube and dual-tube aneroid design that has become a reference standard for accuracy in clinical measurement. Clinicians choose Tycos because the calibrated gauge holds its accuracy over years of use, and the movement is engineered to be recalibratable rather than disposable—a meaningful distinction for facilities that don't want to replace instruments every time a reading drifts.

This collection covers the formats a practice actually needs. The Tycos pocket aneroid units (5090 series) pair a compact palm or pocket gauge with a Size 11 nylon cuff (23–40 cm) for rounds and portable use, with a Size 12 large-adult option (34–50 cm) for larger arms. The Baxter DS66 Trigger Aneroid Gold Series offers a bladderless one-piece cuff that speeds cleaning and cuts down on the tangle of separate tubing and bladders. For fixed clinical stations, the 7670 series mounts to a five-leg mobile stand or the wall, keeping a two-tube adult unit exam-ready between patients.

Getting the cuff size right matters more than most buyers expect—a cuff that's too small reads falsely high, too large reads falsely low. Match the size range to arm circumference, and consider stocking both a standard adult (Size 11) and a large-adult (Size 12) cuff if your patient population varies. All units use a manual inflation pump and dial display, so there are no batteries to manage and no reliance on power at the point of care.
