• Submission Type: Traditional
• Regulation: 21 CFR 870.1130
• Device Class: Class 2

Intended Use

The Mars MS-900S, MS-900SFM & MS-900SPM Auto Inflation Wrist Blood Pressure Monitors are designed to provide signals from which systolic and diastolic pressures can be derived through the use of the oscillometric method. The devices also measure pulse rate.

Device Story

Automatic wrist-worn blood pressure monitors (MS-900S, MS-900SFM, MS-900SPM) utilize oscillometric method to measure systolic/diastolic blood pressure and pulse rate. Device inflates cuff automatically, detects pressure oscillations, and processes signals to derive hemodynamic values. Intended for use in clinical or home settings by patients or healthcare providers. Output displayed on integrated screen for immediate clinical assessment of patient cardiovascular status.

Clinical Evidence

No clinical data provided; substantial equivalence based on technological characteristics and established measurement methodology.

Technological Characteristics

Wrist-worn digital blood pressure monitor; oscillometric sensing principle; automatic inflation/deflation system; battery-powered; digital display output.

Indications for Use

Indicated for non-invasive measurement of systolic and diastolic blood pressure and pulse rate in adults using the oscillometric method at the wrist.

Regulatory Classification

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.
