BP Med 21 is an airbag blood pressure and ECG smartwatch. A side-insert airbag and a piezoelectric ceramic pump take oscillometric blood pressure readings on the wrist, while a Goodix GH3220T chip and nano conductive glass capture an ECG waveform. The 1.95-inch AMOLED display is a full-touch screen for everyday health check-ins.
Airbag Blood Pressure and ECG
BP Med 21 uses a piezoelectric ceramic air pump and a detachable, sealed side airbag in the strap. The watch checks measurement posture and filters readings taken in the wrong position. ECG capture uses a Goodix GH3220T chip and nano conductive glass. A one-tap mini health check records several metrics together. An AI heart-health report in the HealthWear app is for reference only.

FAQ
How does BP Med 21 measure blood pressure?
A piezoelectric ceramic pump inflates a side airbag in the strap. That is the same oscillometric idea used by an upper-arm cuff. The watch checks posture and can read the result aloud. Readings are for reference only.
Does it record an ECG?
Yes. A Goodix GH3220T chip and nano conductive glass capture an ECG waveform, and the HealthWear app can show an AI heart-health report. This is not a medical diagnosis.
Is the blood glucose number a lab result?
No. The non-invasive glucose figure is a wellness estimate. It does not replace a blood test or a doctor's advice.
Is BP Med 21 a medical device?
No. It is a wellness smartwatch. Use it to watch personal trends, and talk to a clinician about diagnosis or treatment.
What colors are available?
Black (black case and black strap) and Beige (gold-tone case and beige strap).
Can I swim with it?
No. IP66 covers rain and splashes. Do not swim, shower, or use a sauna while wearing it.
How long does the battery last?
The 400 mAh battery is rated for about 5–7 days of typical use and more than 30 days on standby. Charging is magnetic.
This product is not a medical device. Blood pressure, ECG, blood glucose estimates, and other readings are for wellness reference only. They are not a diagnosis and must not be used as a medical basis. Consult a healthcare professional for diagnosis and treatment.
