The device also measures the heart rate. The device is for adult use only and measures wrist circumferences from 5 1/4" to 7 3/4". The end user should not have common arrhythmias, such as atrial or ventricular premature beats or atrial fibrillation ## Device Story Daiwa Model 180 is an automatic inflation wrist digital blood pressure monitor. Device uses oscillometric method to detect pressure signals; calculates systolic/diastolic blood pressure and heart rate. Intended for adult home use; patient operates device by securing cuff to wrist. Output displayed on digital screen for user monitoring. Provides non-invasive hemodynamic data to assist in blood pressure management. ## Clinical Evidence No clinical data provided; bench testing only. ## Technological Characteristics Wrist-worn digital blood pressure monitor; utilizes oscillometric sensing principle; battery-powered; digital display; non-invasive measurement. ## Regulatory Identification A noninvasive blood pressure measurement system is a device that provides a signal from which systolic, diastolic, mean, or any combination of the three pressures can be derived through the use of tranducers placed on the surface of the body. ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).
