Intended Use

Electronic Blood Pressure Monitor intended for use in measuring blood pressure and pulse rate in adult patient population. It is intended to measure the diastolic, systolic blood pressures and pulse rate through an inflatable cuff wrapped around the arm. It can be used by medical professionals or at home. The cuff circumference is limited to 22-42 cm.

Device Story

Electronic Blood Pressure Monitor uses oscillometric principle to measure systolic/diastolic blood pressure and pulse rate. Device consists of main unit (screen, buttons, air connector), inflatable arm cuff, air tube, and power source (AA batteries or USB-C). User wraps cuff around upper arm; device inflates/deflates cuff, sensing pressure pulses in radial artery. Internal processor calculates blood pressure and pulse rate from pressure signals. Used in clinical or home settings by professionals or patients. Output displayed on screen; assists in monitoring cardiovascular health. Models YJ320, YJ321E, YJ326E differ by screen type (B&W vs color), cuff detection, and misoperation prompts.

Clinical Evidence

Clinical validation performed per ISO 81060-2:2018 using the same-arm sequential method. Study included 86 adult subjects (49 female, 37 male; age 17-76). Results demonstrated mean error and standard deviation of differences for systolic and diastolic pressure within ISO 81060-2 limits. No adverse effects reported.

Technological Characteristics

Oscillometric measurement; upper arm site. Materials: Nylon (cuff), ABS (cover). Power: 4 AA batteries or USB-C (5V-6V). Connectivity: Standalone. Standards: IEC 60601-1, IEC 60601-1-2, IEC 60601-1-8, IEC 60601-1-11, ISO 80601-2-30, IEC 80369-5. Software: Moderate level of concern.

Indications for Use

Indicated for measuring blood pressure and pulse rate in adult patients via an inflatable arm cuff. Suitable for use by medical professionals or at home. Cuff circumference 22-42 cm.

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.

#### IV Device Description

Electronic Blood Pressure Monitor mainly consist of the main body (include screen display, air tube connector, memory button and start/stop button), cuff, USB cable, air tube, and AA batteries.

Electronic Blood Pressure Monitor that uses the oscillometric principle to measure your blood pressure and pulse rate. The radial artery in the arm changes from blocked to open as the pressure in the cuff tied around the arm changes from high to low, causing the pressure in the cuff to be superimposed on a series of small pressure pulses. The sphygmomanometer senses these signals and, after certain calculations, finds the systolic and diastolic pressures of the radial artery in the body.

Electronic Blood Pressure Monitor can be divided into three models (YJ320、YJ321E、

#### Different 1- Blood pressure measurement range

The Blood Pressure Range of the subject device includes the blood pressure range of predicate devices and meets the requirements of IEC 80601-2-30. Therefore, the difference will not affect the safety and effectiveness of the subject device.

#### Different 2- Power supply

The difference between subject device and predicate device (K222994) is the batteries, the predicate device use Lithium-ion battery, D.C. 3.7V while the subject device use 4 "AA" batteries (d.c.6v) or USB-C INPUT 5V d.c-6V d.c/600mA, but the power supply safety of subject device is justified by the IEC60601-1 electricity test reports. Thus this difference will not affect the safety and effectiveness, therefore this item is considered as substantial equivalence.

#### Different 3- Operation condition

The difference between subject device and predicate device (K222994) is the humidity and Atmospheric pressure, the predicate device is 15%RH-90%RH, 70 kPa -106 kPa, while the subject device is 15%RH-85%RH, 80kPa~105kPa, it is included in predicate device. Therefore, this item is considered as substantial equivalence.

#### Different 4- Storage condition

The difference between subject device and predicate device (K222994) is the humidity

Section 3-4

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

#### K232814

and Atmospheric pressure, the predicate device is 15%RH-90%RH, 70 kPa -106 kPa, while the subject device is 15%RH-85%RH, 80kPa~105kPa, it is included in predicate device. Therefore, this item is considered as substantial equivalence.

#### Different 5- Biocompatibility

The predicate device (K222994) was tested by ISO 10993-5, ISO 10993-10, and the testing part included the battery.

While the main part of subject device that comes into contact with the patient is the cuff, the part that comes into contact with the operator is mainly the cover and cuff. The material of cover is ABS, which is a commonly used material in the market. It has Limited contact with intact skin. Per FDA's 2020 guidance document, Use of International Standard ISO 10993-1, ABS materials are exempt from biological testing. In addition, the cuff has tested by ISO 10993-5 and ISO 10993-10.

Based on the above description, these differences do not affect the achievement of the product's intended use, nor do they compromise the safety of patients and operators.
