Device Story

ROSSMAX Automatic Wristwatch Blood Pressure Monitor (Model RM-4200) is a wrist-worn device for non-invasive blood pressure and heart rate monitoring. It utilizes the oscillometric method to detect pressure oscillations in the wrist artery. The device is intended for over-the-counter use by adult patients. Users apply the device to the wrist; the monitor automatically inflates, measures, and displays systolic/diastolic blood pressure and heart rate on an integrated screen. This provides patients with a convenient method for self-monitoring blood pressure outside of clinical settings, facilitating tracking of cardiovascular health metrics.

Clinical Evidence

No clinical data provided; bench testing only.

Technological Characteristics
