Abstract
A fluidic component intended to be associated with a heating module and in which there is formed a fluidic circuit including a fluidic channel intended for the circulation of a fluid, the fluidic channel including at least one passage for the fluid and a widened portion forming a location produced at the periphery of the passage, the component including a fluidic valve mechanism including at least an actuating element capable of expanding, trapped by at least one body made of a meltable compound in the location.
Claims6
A device, comprising:
- a fluidic component in which there is formed a fluidic circuit comprising a fluidic channel intended for the circulation of a fluid, said fluidic channel comprising at least one passage for said fluid and a widened portion positioned at a periphery of said at least one passage, said component also comprising a fluidic valve mechanism comprising at least an actuating element capable of expanding, trapped by at least one body made of a meltable compound in said location,
- the fluidic circuit comprising a reaction chamber, the fluidic valve mechanism being arranged on the fluidic channel of the fluidic circuit opening into said reaction chamber,
- a heating module designed simultaneously to heat both the reaction chamber in order to perform a detection reaction, and the fluidic valve mechanism in order to expand the actuating element and cause the meltable-compound body of said fluidic valve mechanism to melt so as to initiate operation of said fluidic valve mechanism.
