Intended Use

Transtek Wrist Blood Pressure Monitor TMB-1014-BT is a digital monitor intended for use in measuring blood pressure and heartbeat rate in adult patient population with wrist circumference ranging from 13.5 cm to 21.5 cm (about 5 1/4 - 8 1/2 inches). This device detects the appearance of irregular heartbeats during measurement and gives a warning signal with readings. The Wrist Blood Pressure Monitor compares average blood pressure results to pre-established AHA (American Heart Association) hypertension guideline of 135/85 mmHz. Transtek Wrist Blood Pressure Monitor, TMB-1014-BT is not intended to be a diagnostic device. Contact your physician if hypertensive values are indicated.

Device Story

Wrist-worn oscillometric blood pressure monitor; uses inflatable cuff and electronic pressure sensor to detect pulse waves; microprocessor calculates systolic/diastolic pressure and heart rate; detects irregular heartbeats by comparing pulse wave intervals to mean interval (warning if >25% difference); displays results on LCD; includes Bluetooth module for wireless data transmission to external devices; intended for adult home use; provides blood pressure readings and irregular heartbeat alerts; aids in monitoring blood pressure trends relative to AHA guidelines; not diagnostic; requires physician consultation for hypertensive values.

Clinical Evidence

Bench testing only. No clinical data provided. Device conforms to AAMI/ANSI SP10, IEC60601-1, and IEC60601-1-2 standards.

Technological Characteristics

Oscillometric measurement; electronic pressure sensor; inflatable nylon cuff (13.5-21.5 cm); powered by 2 AAA alkaline batteries; Bluetooth connectivity; LCD display; microprocessor-based control; electromagnetic deflation valve. Conforms to ISO14971, AAMI/ANSI SP10, IEC60601-1, IEC60601-1-2, and FCC Part 15.

Indications for Use

Indicated for adult patients with wrist circumference 13.5-21.5 cm for non-invasive measurement of systolic/diastolic blood pressure and heartbeat rate. Detects irregular heartbeats. Not for diagnostic use.

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. Device Description

Transtek Wrist Blood Pressure Monitor, TMB-1014-BT is designed to measure the systolic and diastolic blood pressure and heartbeat rate of an individual by using a non-invasive technique in which

{1}------------------------------------------------

### TRANSTEK

an inflatable cuff is wrapped around the wrist.

Measurement method to define systolic and diastolic pressure is similar to the auscultatory method but uses an electronic pressure sensor rather than a stethoscope and mercury manometer. The sensor converts tiny alterations in cuff pressure to electrical signals, by analyzing those signals to define the systolic and diastolic blood pressure and calculating heartbeat rate, which is a well-known technique in the market called the "Oscillometric method".

Transtek Wrist Blood Pressure Monitor is single-mounted devices of the main unit and cuff unit. The preformed cuff unit, which is applicable to wrist circumference approximately between 13.5 and 21.5 cm, includes the inflatable bladder and nylon shell. The device consists of the microprocessor, the pressure sensor, the operation keys, the pump, the electromagnetic deflation control valve and the LCD. The subject device is powered by two AAA alkaline batteries.

The device also compares the longest and the shortest time intervals of detected pulse waves to mean time interval and displays a warning signal with the reading to indicate the detection of irregular heartbeat when the difference of the time intervals is over 25%.

Transtek Wrist Blood Pressure Monitor TMB-1014-BT embeds a Bluetooth module that allows it to connect to nearby BT receiving end. The LCD of device displays results. And once measurement is over, the device will start transmission data by BT. Thus users can receive, and display/storage, measurement data from TMB-1014-BT unit through their end devices that embedded BT module.

#### 6. Intended Use of Device

Transtek Wrist Blood Pressure Monitor TMB-1014-BT is a digital monitor intended for use in measuring blood pressure and heartbeat rate in adult patient population with wrist circumference ranging from 13.5 cm to 21.5 cm (about 5 1/4 - 8 1/2 inches).

This device detects the appearance of irregular heartbeats during measurement and gives a warning signal with readings.

The Wrist Blood Pressure Monitor compares average blood pressure results to pre-established AHA (American Heart Association) hypertension guideline of 135/85 mmHz.

Transtek Wrist Blood Pressure Monitor, TMB-1014-BT is not intended to be a diagnostic device. Contact your physician if hypertensive values are indicated.

#### 7. Design Control Activities and Performance Tests Summary

Design control activities for this modification were performed and bench tests have been done. Those performance tests, risk management, and design verification tests provide demonstration that the difference does not raise any new questions of safety and effectiveness.

TMB-1014-BT conforms to the following standards:

ISO14971, Risk management to medical devices

{2}------------------------------------------------

### TRANSTEK

AAMI/ANSI SP10, Safety and performance characteristics

IEC60601-1, Electrical safety; IEC60601-1-2, Electromagnetic compatibility

FCC Part 15, EMI tests of FCC Radiation & RF rules and regulations

Explanation: The cuff of TMB-1014-BT is identical to the predicate's cuff, and the new wireless function does not affect blood pressure monitor measurement function. Therefore we have not done the ISO10993 test and Clinical test.

### 8. Summary of Substantial Equivalence

8.1 Difference between proposed device and the predicate device

The only difference between the two devices is that TMB-1014-BT add-on a Bluetooth data communication, what user option, which can transmit measurement results to those end devices that embedded a BT module.

### 8.2 Discussion

The Transtek Wrist Blood Pressure Monitor TMB-1014-BT has identical indication for use, fundamental scientific technology, cuff, energy type, environmental specifications, dimensional specifications, performance specifications, and similar software/firmware, functions, labeling to the predicate device.

The only function difference between TMB-1014-BT and the predicate device is that the TMB-1014-BT provides user an optional wireless (Bluetooth) data transmission. It is an add-on function that is entirely independent from the blood pressure monitor measurement function, which does not reply on the wireless connection to carry out a blood pressure measurement and heartbeat rate analysis and display its results. Thus the BT data transmission does not affect the safety and effectiveness of the wrist blood pressure monitor function.

All required design control activities have been implemented and all applicable performance tests have been done according with demands of FDA guidance document "Non-Invasive Blood Pressure (NIBP) Monitor Guidance" FDA March 10, 1997. We found that the modified device does not create new significant risk.

#### 9. Conclusions

The Transtek Wrist Blood Pressure Monitor TMB-1014-BT is substantially equivalent to the predicate device TMB-1014 by having the identical indication for use, identical technologies, and an add-on function which does not impact the safety and effectiveness of the device.
