Intended Use

Fully Automatic Electronic Blood Pressure Monitor is for use by medical professionals or at home and is a non-invasive blood pressure measurement system intended to measure the diastolic and systolic blood pressures and pulse rate of an adult individual by using a non-invasive technique in which an inflatable cuff is wrapped around the upper arm. The cuff circumference is limited to 22cm-48cm.

Device Story

Device is a non-invasive, oscillometric blood pressure monitor for adult use in clinical or home settings. It utilizes an inflatable upper arm cuff and a silicon-integrated pressure sensor to detect arterial oscillations. The device processes pressure signals to calculate systolic/diastolic blood pressure and pulse rate; it also identifies irregular heartbeats. Results are displayed on an integrated LCD screen. The device includes memory storage for multiple readings and provides averaged results. It is operated by the patient or a healthcare provider. The output allows users to monitor blood pressure trends and identify potential cardiovascular irregularities, supporting clinical decision-making regarding hypertension management.

Clinical Evidence

No new clinical testing performed. Clinical performance is established by referencing clinical test reports of previously cleared devices (K083246, K102939, K120672) that share identical algorithms and design principles. Accuracy verified against ISO 81060-2 criteria.

Technological Characteristics

Oscillometric measurement via silicon-integrated pressure sensor. Powered by 6V DC (AA or AAA batteries). Dimensions vary by model (e.g., 139.4mm x 93.8mm x 41.8mm). Connectivity: Standalone. Compliance: IEC 60601-1, IEC 60601-1-2, IEC 60601-1-11, IEC 80601-2-30. Algorithm: Amplitude-based oscillometric analysis.

Indications for Use

Indicated for adult individuals requiring non-invasive measurement of systolic and diastolic blood pressure and pulse rate via an upper arm cuff (22-48cm circumference). For use by medical professionals or at home.

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.

Dear Liu Yi:

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 (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 located 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.

# 8.0 Discussion of Non-Clinical Testing

Non-clinical tests were conducted to verify that the proposed device met all design specifications. The test results demonstrated that the proposed device complies with the following standards:

- . IEC 60601-1:2005/(R)2012 And A1:2012, C1:2009/(R)2012 And A2:2010/(R)2012 (Consolidated Text) Medical Electrical Equipment - Part 1: General Requirements For Basic Safety And Essential Performance (IEC 60601-1:2005, MOD)
- . IEC 60601-1-2:2014,Medical Electrical Equipment -- Part 1-2: General Requirements For Basic Safety And Essential Performance -- Collateral Standard: Electromagnetic Disturbances -- Requirements And Tests
- IEC 60601-1-11 Edition 2.0 2015-01 Medical electrical equipment Part 1-11: ● General requirements for basic safety and essential performance - Collateral Standard: Requirements for medical electrical equipment and medical electrical systems used in the home healthcare environment
- IEC 80601-2-30:2009 & A1:2013,Medical Electrical Equipment Part 2-30: ● Particular Requirements For The Basic Safety And Essential Performance Of Automated Noninvasive Sphygmomanometers

{8}------------------------------------------------

None of the tests demonstrate that the new Blood Pressure Monitors raises new questions of safety and effectiveness as compared to the predicate

# 9.0 Clinical Test

Comparison and evaluation are carried out between the subject device and cleared devices, and it is showed that:

The proposed devices KD-5810, KD-5810B, KD-5811 and KD-5920TL has the same algorithm and design principle with cleared device KD-5961 (K083246), so the clinical test report of KD-5961can be used as a reference when considering the clinical effect of KD-5810, KD-5810B, KD-5811 and KD-5920TL.

The proposed devices KD-552 has the same algorithm and design principle with cleared device BP3 (K102939) and BP5 (K120672), so the clinical test report of BP3 (K102939) and BP5 (K120672) can be used as a reference when considering the clinical effect of KD-552.

Accuracy of the blood pressure monitors for the clinical test report was verified by meeting criteria 1 and criteria 2 of ISO 81060-2.

## 10. Comparison to the Predicate Device and Conclusion

The conclusion drawn from the nonclinical tests and clinical test demonstrate that the subject device, Fully Automatic Electronic Blood Pressure Monitor (KD-5810. KD-5810B, KD-5811, KD-5920TL and KD-552), is substantially equivalent to the Fully Automatic Electronic Blood Pressure Monitor KD-5031M (K183534) and KD-926 (K162668).

The subject devices are very similar with its predicate device in the intended use, design principle, materials, performance and applicable standards. Their appearance, the memory capacity, the average function, and MCU is different.

However, the tests in this submission demonstrates that these small differences do not raise any new questions of safety and effectiveness and the subject device is as safe, as effective and performs as well as or better than the legally marketed predicate K183534 and K162668.
