The description details calculations based on Bioelectrical Impedance Analysis (BIA) using programmed variables (electrical impedance, height, weight, age, and gender). There is no mention of AI, ML, or any learning algorithms. The calculation method is explicitly stated as the Bioelectrical Impedance Method, which is a standard physiological measurement technique.
No
The device is a body scale that measures various body composition metrics. It does not claim to treat, diagnose, cure, or prevent any disease or condition.
No
Explanation: A diagnostic device is used to detect, diagnose, or monitor a disease, condition, or health status. This device measures body composition parameters (weight, fat, water, muscle, bone, visceral fat, DCI) for generally healthy adults, which are indicators of overall health but not for diagnosing medical conditions.
No
The device description explicitly states it is a "Wi-Fi body scale" and describes physical components like electrodes and the process of stepping on the scale, indicating it is a hardware device with internal software.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are medical devices intended for use in vitro for the examination of specimens, including blood, tissue, and urine, derived from the human body, in order to provide information concerning a physiological or pathological state, or a congenital abnormality, or to monitor therapeutic measures.
- Device Function: The Wi-Fi body scale, model HS5, measures body composition (weight, fat, water, muscle, bone, visceral fat, DCI) by passing a small electrical current through the body and analyzing the impedance. This is an in vivo measurement (within the living body), not an in vitro examination of a specimen outside the body.
- Intended Use: The intended use is to measure body composition in generally healthy adults, not to diagnose a disease or condition based on the analysis of a biological specimen.
Therefore, while it is a medical device, it falls under the category of devices that perform measurements directly on the body, rather than analyzing samples taken from the body.
N/A
Intended Use / Indications for Use
Wi-Fi body scale, model HS5 is indicated to measure body weight, estimate body fat, body water percentage, body muscle mass, bones mass, visceral fat rating and daily calorie intake (DCI) using BIA (bioelectrical impedance analysis). This product is for use by generally healthy adults,,who are not ill, feverish, have a chronic or acute disease, or a condition that affect the level of hydration such as pregnancy.

Device Description
The patient steps on the scale device, where four electrodes are located. The patient must step on the electrodes with bare feet, with normal moisture. Through harmless current stimulation of 500 uA, at 50 kHz, the Wi-Fi body scale calculates the body fat percentage. This calculation is done via the Bioelectrical Impedance Method. The current is passed through the body and the impedance of the body determines the body fat. The calculation is based upon electrical impedance, height, weight, age, and gender. The calculation is performed via internal software, which uses the variables programmed in by the user. Wi-Fi body scale, model HS5 can be used with an iPod Touch, iPhone or iPad.

8.0 Performance summary
Electrical, mechanical, environmental safety and performance testing according to standard EN/IEC 60601-1 and EN/IEC 60601-1-2. Clinical testing was used to validate the effectiveness and accuracy of the device. All test results were satisfactory.
9.0 Comparison to the predict device and the conclusion
Our device Wi-Fi body scale, model HS5 is substantially equivalent to the ody Analysis Scale, Model BG 17 whose 510(k) number is K110928.
The two devices are very similar in the intended use, the design principle, the material, the energy source and the applicable standards. Wi-Fi body scale, model HS5 can be used with an iPod Touch, iPhone or iPad.
However, the test in this submission provides demonstration that these small differences do not raise any new questions of safety and effectiveness.
