VALVE FOR USE IN MICROFLUIDIC STRUCTURES

A valve for use in microfluidic structures. The valve uses a spherical member, such as a ball bearing, to depress an elastomeric member to selectively open and close a microfluidic channel. The valve may be operated manually or by use of an internal force generated to shift the spherical member to i...

Beschreibung
Zusammenfassung:	A valve for use in microfluidic structures. The valve uses a spherical member, such as a ball bearing, to depress an elastomeric member to selectively open and close a microfluidic channel. The valve may be operated manually or by use of an internal force generated to shift the spherical member to its activated position. La présente invention concerne une valve s'utilisant dans des structures microfluidiques. Cette valve fait intervenir un élément sphérique, tel qu'un roulement à billes, qui permet d'enfoncer un élément élastomère en vue d'ouvrir et de fermer sélectivement un canal microfluidique. Cette valve peut être commandée manuellement ou au moyen d'une force interne produite pour décaler l'élément sphérique dans sa position d'activation.
