Powered by two AAA batteries; includes auto-power-off feature. Provides non-invasive monitoring of blood pressure and pulse rate to assist users in tracking cardiovascular health.

Clinical Evidence

Clinical studies conducted per ANSI/AAMI SP 10-1992 confirmed accuracy criteria compliance. Additional testing included electrical, mechanical, and environmental integrity, high/low altitude performance, vibration/shock resistance, life cycle testing, and intra-device variability. Cuff material biocompatibility evaluated by TUV Product Service. Electromagnetic interference testing performed by ONETECH. Software validation documented.

Technological Characteristics

Oscillometric measurement system; wrist-cuff form factor. Powered by two AAA batteries. Features automatic inflation pump and constant air release valve (2-3 mmHg/sec). LCD display for systolic/diastolic pressure, heart rate, date, and time. Biocompatible cuff materials. Complies with ANSI/AAMI SP 10-1992 and international electromagnetic interference standards.

Indications for Use

Indicated for adult patients with arm circumferences between 5.5 and 7.5 inches for the measurement of systolic/diastolic blood pressure and pulse rate.

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.

#### 5. Description :

MD-880B, MD-900T models are oscillometric systems intended for measurement of blood pressure and purse rate in a home care environment.

- 1)MD-880B : MD-880B employs the oscillometric method for measurement of blood pressure and heart rate. A cuff is wrapped around the wrist and inflates to a pressure sufficient to initially interrupt blood flow. As cuff pressure is gradually reduced, a sensor inside the cuff detects the small oscillations in pressure against the cuff produced by expansion and contractions of the arteries in the wrist in response to each heart beat. The amplitude of these pressure waves is measured to monitor changes in the character of blood flow and the corresponding cuff pressure at which these changes occur is detected. The systolic and diastolic pressure in millimeters of mercury, followed by the heart rate in beats per minute, is displayed as a numerical value on the LCD.
The cuff is automatically inflated by a built-in air pump(low noise) and selected inflation level by checking heart beat signal. The inflation is automatically activated in about 1 second after power on. The three-row, 9-digit LCD displays systolic pressure(upper 3digits) and diastolic pressure(middle 3 digits) and heart rate(lower 3-digits). In addition, the date and time are displayed(8-digit).

MD-880B incorporates a constant air release valve to regulate deflation rate, within limits of 2 or 3 mmHg/sec to optimize measurement accuracy. The pressure measurement range is 20 to 285 mmHq. And keys are consisting of push-button switch instead of touch screen(MD-900T) for low cost model.

MD-880B is powered by two AAA-size batteries and are equipped with a circuit that will automatically cut off power after about 1 minutes of non-use to conserve battery charge.

- 2) MD-900T : MD-900T employs the oscillometric method for measurement of blood pressure and heart rate. A cuff is wrapped around the wrist and inflates to a pressure sufficient to initially interrupt blood flow. As cuff pressure is gradually reduced, a sensor inside the cuff detects the small oscillations in pressure against the cuff produced by expansion and contractions of the arteries in the wrist in response to each heart beat. The amplitude of these pressure waves is measured to monitor changes in the character of blood flow and the corresponding cuff pressure at which these changes occur is detected. The systolic and diastolic pressure in millimeters of mercury, followed by the heart rate in beats per minute, is displayed as a numerical value on the LCD.
The cuff is automatically inflated by a built-in air pump(low noise) and selected inflation level by checking heart beat signal. The inflation is automatically activated in about 1 second after power on. The three-row, 9-digit LCD displays systolic pressure(upper 3-

digits) and diastolic pressure(middle 3 digits) and heart rate(lower 3-digits). In addition, the date and time are displayed(8-digit).

MD-900T incorporates a constant air release valve to regulate deflation rate, within limits of 2 or 3 mmHg/sec to optimize measurement accuracy. The pressure measurement range is 20 to 285 mmHg.

MD-900T is powered by two AAA-size batteries and are equipped with a circuit that will automatically cut off power after about 1 minutes of non-use to conserve battery charge.

- 6. Indication for use :
Measuring Systolic and Diastolic blood pressure and pulse rates in adult patients with arm circumferences between 5½~ 7½ inches using the oscillometric method

- 7. Comparison with predicate device :
MD-880B, MD-900T models have been compared with the automatically inflated Omron Healthcare model HEM-630 and Meditec model MD-770. The intended use of the 2 subject devices and the predicate devices is the same. The principle of operation(oscillometric measurement) is identical and there are no significant differences on operating features. It is concluded that there are no technologic differences between the subject and predicate devices that raise new questions concerning either safety or effectiveness.

- 8. Performance Data :
The measurement performances of the 2 MEDITEC systems have been evaluated in clinical studies conducted on accordance with ANSI/AAMI SP 10-1992 and found to comply fully with the accuracy criteria established in the standard. Safety and functional testing including electrical characteristics, mechanical and environmental integrity under various operating and storage conditions, high and low altitude performance, resistance to vibration and shock, life cycle testing, and intra-device variability has been performed with satisfactory results. The biocompatibility of cuff materials was evaluated favorably by TUV Product Service. Electromagnetic interference studies have been conducted by ONETECH Testing & Evaluation Laboratories and found to comply with international standards. Software validation have been performed and documented. It is concluded that the subject devices comply with all relevant safety and performance standards.

- 9. Conclusions :
In accordance with the Federal Food, Drug and Cosmetic Act, 21 CFR Part 807, FDA's "Guidance document for the preparation of premarket notifications {510(k)'s} for NON-
