Yuwell YE660E - Medaval

Description:

The Yuwell YE660E 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. It is intended for self-measurement and home use.

Assessment:

The technology used in the Yuwell YE660E, to measure blood pressure, has failed in a clinical validation study, in a general population, according to a recognised standard protocol, as published in a peer-reviewed publication. It has also been compared to a clinically validated device, but the results of the equivalence study have not been published and cannot be verified; nor can the protocol be checked for compliance 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.
BP	Stride BP	Self-measurement for adults (Preferred)	Equivalence claim without published evidence
