Transfusion and infusion devices use the sampling site, fluid path, non-pyrogenic and one-way valve symbols (5.6.1 to 5.6.3, 5.6.6) as applicable; in the drops per millilitre symbol (5.6.4) the example figure is replaced by the device's actual drop rate, and in the liquid filter symbol (5.6.5) the example pore size is replaced by the filter's nominal pore size.
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
