MICROVANNE A ACTIONNEMENT PYROTECHNIQUE

摘要

The microvalve has a mini-piston moving due to thrust of gases given off by firing of pyrotechnic charge (20). An aperture establishes communication between ends of microchannels of a micorfluidic component. A mini-position is formed in a substrate, when the ends between which the communication is established is open out on to a face of another substrate. The mini-position has a rod (24) that slides into a transverse slot (25) to form an aperture by a transverse orifice, when a clot is placed between the ends of the microchannels.
