Description:
The Rossmax CH91 (V1) is a surface-placed semi-automatic blood pressure monitor. Medaval has not found evidence proving the accuracy of its blood pressure measurement technology.

This device has been discontinued by the manufacturer but may be available through certain outlets.
Assessment:
There appears to be no peer-reviewed clinical validation information available on the technology used in the Rossmax CH91 (V1) to measure blood pressure. However, this device appears to be very similar to another device by the same manufacturer or a device within a family of equivalent devices. At least one validation needs to be published and equivalence needs to be proven according to a protocol compliant with (EU) 2017/745 and MEDDEV 2.7/1 rev 4.
