Omron M1 Classic (HEM-442C-E)

Description:

The Omron M1 Classic (HEM-442C-E) is a surface-placed semi-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. This device has been discontinued by the manufacturer but may be available through certain outlets.

Assessment:

The technology used in the Omron M1 Classic (HEM-442C-E), to measure blood pressure, has been compared to a clinically validated device, but not 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.
BP	ESH (Europe)	Self-measurement	Published evidence
