摘要:
The present invention relates to an item (10) having liquid (L) storage and/or discharge properties, in particular a bandage, comprising: - a liquid-permeable proximal structure (20), consisting of a material capable of inflating in the presence of liquid (L), - a distal structure (30) capable of draining a liquid (L), -a hydrophobic and non-absorbent spacer structure (40) extending between the distal (30) and proximal (20) structures, and being capable of locally limiting, when said material is not inflated, the exchange of liquid between the distal and proximal structures by maintaining a gap between said structures, and of authorising a local expansion of the proximal structure in at least one zone (P) where said material is inflated in response to coming into contact with a liquid, said expansion causing the proximal and distal structure to move together locally and the transfer of said liquid from the zone of the proximal structure (20) having undergone expansion to the distal structure (30).

The invention relates to a flow meter comprising a first chamber (11) and a second chamber (13) that are interconnected by a channel (12), the first chamber being provided with a first deformable membrane (11') and a first and a second gauge (R1, R2), the second chamber (13) being provided with a second deformable membrane (13') and a third and a fourth gauge (R3, R4), the four gauges forming a Wheatstone bridge.
摘要:
L'invention concerne un dispositif pour la séparation et concentration de particules présentes dans un fluide, comprenant : ● un premier microcanal (1), ayant au moins une première ouverture (10, 12) ; ● au moins un deuxième microcanal (5), ayant au moins une deuxième ouverture (50), et une extrémité (51) ; ● le premier microcanal (1) entourant le deuxième microcanal au niveau de ladite extrémité (51) ; ● le premier microcanal (1) et le second microcanal (5) sont reliés, au niveau de la dite extrémité (50), par au moins un nanocanal ( 3 ), le(s) nanocanal(ux) formant une restriction entre le premier microcanal et le second microcanal, dont la géométrie est figée durant une période temporelle prédéterminée ; ● un capot (13) délimitant le premier microcanal, le deuxième microcanal et le nanocanal au niveau de ladite extrémité. Application pour la séparation et concentration de particules d'échantillons biologiques, tels que virus, molécules d'ADN ou de synthèse.
摘要:
The invention concerns a device for moving a small volume of liquid under the effect of an electric control, comprising a first substrate with hydrophobic surface (29) provided with electrically conductive means (24), second electrically conductive means (30) arranged opposite the first conductive means. The invention is characterized in that it comprises third conductive means (32), forming with the second conductive means for analyzing or heating a volume of liquid.
