Abstract
The invention relates to a miniaturised fluid flow regulating device comprising a fluid flow channel with an inlet portion, an outlet portion and a flow regulation passage between the inlet portion and the outlet portion, an elongated beam element arranged in the flow channel, such that a pressure difference over the inlet portion and the outlet portion causes the beam element to bend and regulate fluid flow in the flow regulation passage. The invention further relates to a breath analysis device comprising such a flow regulating device for regulating a flow of exhaled breath.
