Abstract

A method of orthonasal evaluation of a fluid, comprising the metering of the fluid in a defined quantity to provide a desired orthonasal combination, metering being accomplished from a plurality of fluid reservoirs, each containing a different fluid, according to inputs from a control unit, the defined quantities being provided by means of a metering device comprising (a) a plurality of channels, each corresponding with an individual reservoir, the channels being formed in a surface and adapted to receive a flow of fluid, and which channels are covered by an elastically-deformable membrane; (b) valve means associated with each channel, comprising an element mounted orthogonally to each channel and capable of moving into fluid flow-blocking contact against the pressure of the membrane, the profile of the element matching that of the channel profile at the point of contact; and (c) valve-closing means. The method is particularly quick and convenient, and the device is capable of miniaturisation to an extent previously not possible.
