#### 5. Device Description

The Blood Pressure Monitor is designed to measure the systolic and diastolic blood pressure and pulse rate of an individual by using a non-invasive technique in which an inflatable cuff is wrapped around the upper arm. Our method to define systolic and diastolic pressure is similar to the auscultatory method but uses an electronic pressure sensor rather than a stethoscope and mercury manometer. The sensor converts tiny alterations in cuff pressure to electrical signals, by analyzing those signals to define the systolic and diastolic

{4}------------------------------------------------

blood pressure and calculating pulse rate, which is a well-known technique in the market called the "Oscillometric method".

When using the device, users will be able to monitor their blood pressure and their pulse rate. The device will give metrics about heart health:

- Systolic blood pressure
- Diastolic blood pressure
- Pulse rate

The device should be placed on the left upper arm during all the measurement duration. The measurement lasts between 30 seconds and 3 minutes depending on the selected mode by the user. The measurement can be longer if the user selects the triple measurement mode (three blood pressure measurements in a row to give an average).

Users will get an instant feedback after the measurement thanks to a LED matrix located on the tube part of the device.

# WPM05 (BPM Connect)

The device synchronizes with Withings application and Withings server via Bluetooth or Wi-Fi connectivity.

# WPM06 (BPM Connect Pro)

The device synchronizes with third-party applications by cellular, Wi-Fi or Bluetooth connectivity. On the mobile application, users have access to their historic and more contents around each metrics.

#### 6. Intended use & Indication for use

The device is a digital monitor intended for use in measuring blood pressure and pulse rate. The device is intended to be used in a human adult population with an arm circumference of 9 inches (22 cm to 42 cm). The device is intended for indoor use.

#### Comparison to the Predicate Device 7.

{5}------------------------------------------------

{6}------------------------------------------------

Justification of difference:

Different (1): The substantial difference of the intended use is the arm circumference ranging. The subject device is within the range of the predicate device. The subject device was validated according to ISO 80601-2-30 and ISO 81060-2. The performance data can demonstrate this difference does not raise different questions of safety and effectiveness.

Different (2): The battery is different. The IEC 60601-1 test report can demonstrate that the subject device can maintain the safety and performance with the battery. Thus, this difference does not raise different questions of safety and effectiveness.

Different (3): Compared with the predicate device reguires less strict operation and storage environment. The IEC 60601-1-11 test report can demonstrate that the subject device can maintain the safety and performance within the operation and storage environment. Thus, this difference does not raise different questions of safety and effectiveness.

Different (4) (5): The blood pressure measurement range and accuracy are different. The pulse rate measurement range and accuracy are different. The IEC 80601-2-30 can demonstrate that the subject device can maintain the safety and performance within the measurement range. Thus, the difference does not raise different questions of safety and effectiveness.

Different (6): The wireless module is different. However, the wireless function is same. The monitor can transmit the measurement result through wireless and display the measurement on the mobile application. Thus, this difference does not raise different questions of safety and effectiveness.
