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 wrist. The cuff circumference is limited to 14cm-25cm.

Device Story

The Fully Automatic Electronic Blood Pressure Monitor (models KD-743V, KD-743B, KD-752) is a non-invasive device for measuring systolic/diastolic blood pressure and pulse rate. It utilizes an inflatable wrist cuff and an oscillometric pressure sensor to detect arterial pressure oscillations. The device processes these signals to calculate blood pressure and pulse, displaying results on an LCD screen. It includes features for irregular heartbeat detection and blood pressure classification. Used in clinical or home settings by patients or medical professionals, the device provides immediate feedback to assist in monitoring cardiovascular health. Data is stored in internal memory, with some models offering averaging functions (e.g., last 3 readings, 7-day averages). The device operates on DC power (batteries).

Clinical Evidence

No new clinical trials were conducted. Substantial equivalence is supported by clinical test reports from reference devices KD-7961 (K090769) and KD-972 (K121470), which share the same algorithm and design principles. Accuracy was verified against ISO 81060-2 criteria.

Technological Characteristics

Oscillometric measurement via silicon integrated pressure sensor. Powered by 2x1.5V AAA batteries. Wrist cuff circumference 14-25cm. LCD display (backlight on KD-752). Complies with IEC 60601-1, IEC 60601-1-2, IEC 60601-1-11, and IEC 80601-2-30. Algorithm: Amplitude-based.

Indications for Use

Indicated for adult individuals requiring non-invasive measurement of systolic and diastolic blood pressure and pulse rate via a wrist-worn inflatable cuff (14cm-25cm circumference). Suitable for use by medical professionals or for home 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.

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.

## 8.0 Discussion of Non-Clinical Testing

Non-clinical tests 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

None of the tests demonstrate that the new Blood Pressure Monitors raise 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-743V and KD-743B has the same algorithm and design principle with cleared device KD-7961 (K090769), so the clinical test report of KD-7961 can be used as a reference when considering the clinical effect of KD-743V and KD-743B.

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

The proposed devices KD-752 has the same algorithm and design principle with cleared device KD-972 (K121470), and so the clinical test report of KD-972 can be used as a reference when considering the clinical effect of KD-752.

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-743V, KD-743B, KD-752), is substantially equivalent to the Fully Automatic Electronic Blood Pressure Monitor KD-753 whose 510(k) number is K183535 and KD-721 whose 510(k) number is K163276.

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 is different, and MCU used is different.

However, the tests in this submission demonstrates that these 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 K183535 and K163276.
