Description:
The Rossmax X9 BT is an automatic blood pressure monitor. The accuracy of its blood pressure measurement technology has yet to be proven to MDR requirements. Blood pressure measurements are taken from the upper arm. With atrial fibrillation detection, it is intended for professional use.
Assessment:
There appears to be no peer-reviewed clinical validation information available on the technology used in the Rossmax X9 BT to measure blood pressure. However, this device appears to be very similar to a validated device by the same manufacturer, but equivalence needs to be proven according to a protocol compliant with (EU) 2017/745 and MEDDEV 2.7/1 rev 4.
Recommendations:
| Accuracy Assessment | Recommendation | Basis | |
| BP | Medaval | None | Although equivalence to another device is claimed, this has not been tested to MDR requirements. |
