The Huibao BE-136 Body Fat Scale measures body weight and impedance for the person standing on the four foot electrodes, and then estimates and displays the information of body weight, total body fat percentage, total body water percentage, bone mass, and daily calorie intake(DCI) using Foot-to-Foot BIA(bioelectrical impedance analysis) method. BF-136 is intended for the healthy person whose age is between 10 and 80 years old

Device Story

Huibao BF-136 is a program-controlled body composition analyzer; utilizes foot-to-foot bioelectrical impedance analysis (BIA). Device inputs: body weight and electrical impedance measured via four foot electrodes (100 µA/30KHz current). Device transforms inputs by calculating body composition metrics based on user parameters. Outputs: body weight, total body fat percentage, total body water percentage, bone mass, and daily calorie intake (DCI) displayed to user. Used in home or clinical settings; operated by the individual standing on the scale. Output provides health information to the user for personal monitoring.

Clinical Evidence

Clinical performance study compared BF-136 to predicate TANITA BC-534. Study included 35 male and female subjects aged 10-80. Primary endpoints were body fat percentage, water percentage, bone mass, and DCI. Results showed deviations between devices were within 10% (Max deviation 9.09%, Min deviation -8.70%). No adverse effects reported.

Technological Characteristics

Body composition scale; foot-to-foot BIA sensing principle. Energy source: electrical. Dimensions/form factor: scale with four foot electrodes. Connectivity: standalone. Standards: EN/IEC 60601-1 (electrical safety), EN/IEC 60601-1-2 (EMC). Software: program-controlled.

Indications for Use

Indicated for healthy individuals aged 10 to 80 years for the measurement of body weight and estimation of body composition metrics including body fat percentage, total body water percentage, bone mass, and daily calorie intake.

Regulatory Classification

Identification

An impedance plethysmograph is a device used to estimate peripheral blood flow by measuring electrical impedance changes in a region of the body such as the arms and legs.

Discussion of Non-Clinical Tests Performed Determination of Substantial Equivalence: Compliance is ensure via the following voluntary standard testing reports: 1> EN/IEC 60601-1 for electrical safety compliance tested by accredited laboratory 2> EN/IEC 60601-1-2 for EMC compliance tested by accredited laboratory.
- Summary discussion of the clinical tests performed for determination of Substantial Equivalence: ర్లో Performance clinical test for the comparison of total body fat percentage, total body water percentage, bone mass, and daily calorie intake(DCI) was performed by manufacturer. For the clinical test, 35 male and female subjects whose age are between 10 and 80 years old were chosen as the investigated users to take comparison measurement. For the comparison, it is considered acceptable that the deviation between our device Huibao/BF-136 and the predicate device TANITA/BC-534(K040778) is within 10%. Consequently, the maximum and minimum deviation of comparison testing and results are as the following table:

| Comparison feature | Max. deviation | Min. deviation | Verdict |
|-------------------------|----------------|----------------|------------|
| 1. Body Fat Percentage | 9.09 % | -8.70 % | Acceptable |
| 2. Water Percentage | 8.83 % | -3.33 % | Acceptable |
| 3. Bone Mass | 9.09 % | -5.88 % | Acceptable |
| 4. Daily calorie intake | 1.18 % | -1.45 % | Acceptable |

During the execution of the clinical test, no any adverse effect or complication was encountered for every individual who was subjected to the clinical test.

#### Conclusions ்.

Based on the clinical test comparison results for the measurement performance of total body fat percentage, total body water percentage, bone mass, and daily calorie infrake(DCI) performed by manufacturer as presented in section 8, and the completed electrical safety and EMC testing report performed by accredited laboratory presented in section 7, it was concluded that the Hubao Body Fat Scale, model BF-136 as well as the predicate device, the TANTA InnerScan Body Composition Monitor model BC-534(K040778), had been proven to meet the relevant safety and efficacy requirements of the device, and therefore is considered as Substantial Equivalence.
