## Indications for Use

The Arm-type Fully Automatic Digital Blood Pressure Monitors are intended to measure blood pressure (systolic and diastolic) and pulse rate of adults and adolescents over 12 years of age with circumference ranging from 22cm to 42cm and 40cm to 56cm.

## Device Story

Arm-type oscillometric blood pressure monitor; uses piezoelectric pump for cuff inflation and electric valve for rapid deflation; extracts pulse waveform data during inflation. Microprocessor software analyzes waveforms to calculate systolic/diastolic pressure and pulse rate; detects irregular heartbeats if pulse interval variance exceeds 25%. Used in home or clinical environments by patients or clinicians. Models with Bluetooth (2.4GHz BLE) transmit data to external terminals/apps for display/storage. Output includes LCD results, irregular heartbeat warnings, WHO classification, and trend charts. Benefits include non-invasive, automated monitoring of cardiovascular metrics to support clinical decision-making.

## Clinical Evidence

No new clinical testing performed. Accuracy leveraged from previously cleared devices (K230566, K250548). Leveraged studies used ISO 81060-2:2018+AMD2020 protocol with manual mercury sphygmomanometer reference. Study 1 (n=95) and Study 2 (n=85) confirmed accuracy within acceptable limits. Bench testing verified equivalence of core algorithms and performance characteristics.

## Technological Characteristics

Oscillometric measurement; piezoelectric pump; solenoid valve; 4 AAA batteries or AC adapter. Upper arm cuff (22-42cm or 40-56cm). Connectivity: 2.4GHz BLE module (select models). Standards: IEC 60601-1, IEC 80601-2-30, IEC 60601-1-11, IEC 60601-1-2, ISO 10993-1/5/10/23. Software: Embedded microprocessor algorithm for waveform analysis.

## 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.

Dear Yingting Lan:

We have reviewed your section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (the Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database available at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls.

## 5. Device Description:

The Arm-type Fully Automatic Digital Blood Pressure Monitors(DBP-6186 Plus, DBP-6286B Plus, DBP-61E3 Plus, DBP-61E2 Plus, DBP-62E3B Plus, DBP-62E2B Plus) are intended to measure blood pressure (systolic and diastolic) and pulse rate of adults and adolescents over 12 years of age with circumference ranging from 22cm to 42cm and 40cm to 56cm.

They are automatic, non-invasive, blood pressure measurement system for over-the-counter (OTC) use at home and clinical environment . The systolic and diastolic pressures are determined using the oscillometric method, where the cuff is inflated with an integral controllable piezoelectric pump and deflates via an electric automatic rapid deflation valve. During inflation measurements, an electric pump within the main unit slowly inflates the arm cuff, generating cuff pressure which is monitored and from which pulse waveform data is extracted. This waveform data is analyzed by software algorithms within the microprocessor to determine pulse rate, systolic pressure, and diastolic pressure. The cuff can measure pressure range from 0 to 299mmHg, and the pulse rate range from 30 to 180 beats/min. The pulse rate measurement is compare 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%.

DBP-6286B Plus, DBP-62E3B Plus, DBP-62E2B Plus with bluetooth function can be used as a stand-alone unit to finish the blood pressure measurement or in conjunction with the APP through embed a 2.4GHz BLE module that allow users to connect with nearby BT receiving terminal. Once measurement is over, the LCD display of the device appears results. And the device will start to transmit data to the pair-up terminal automatically.

With the use of software (including APP) and wireless communication module, the wireless software function and hardware function are solely intended to transfer, store, convert formats, or display medical device data and results (blood pressure and pulse rate readings), without

# Equivalence Justification via Bench Testing:

Comprehensive bench testing and internal simulation analyses were conducted to demonstrate equivalence. The testing confirmed:

Equivalence between the subject device models and the previously cleared model DBP-6286B from K250548, DBP-6279B from K230566, as they share the same core algorithm and essential performance characteristics.

# Clinical Coverage Discussion:

The subject devices share the same upper-arm application site as previous portable models DBP-6279B, DBP-6286B cleared by JOYTECH. Combined with the bench testing equivalence proof between the subject models, the previously cleared model DBP-6279B, DBP-6286B, the safety and effectiveness of all subject devices are adequately demonstrated. The above clinical studies can cover the subject devices. No additional study is needed.

# 10. Conclusions:

The subject device and predicate devices have same Measuring principle, measuring method, are designed for the measurement of blood pressure, pulse rate and detection of irregular pulses

for home use. The minor difference between the subject devices and the predicate devices have been evaluated and determined to not raise any new issues of safety or effectiveness.

Therefore, the new models as mentioned on this submission are considered substantial equivalent to the predicate devices.
