In recent years, international guidelines including those by WHO/ISH (World Health Organization/International Society of Hypertension) have shown the importance of continuously managing blood pressure not just in medical institutions but also in daily life. In response, interest in regular blood pressure management at home, including blood pressure measurement, is rising.
This product inherits the simple operability developed from our currently available entry models "CHUN380" and "CHWL350," and is equipped with Bluetooth® functionality. You can connect with the dedicated app "Health Scan" with the push of a single button, allowing for automatic transfer of measurement data. This reduces the hassle of recording entries in traditional paper blood pressure diaries and supports users in easily managing daily blood pressure changes through visual graphs in the app, enabling convenient health management via smartphone.
Furthermore, with a universally designed consideration for first-time blood pressure monitor users, this product contributes to maintaining the health of a broad user demographic.
The Company will continue to expand its lineup of products compatible with "Health Scan" to support ongoing health management in daily life.
