Patent

CA 2302675

The present invention generally provides a micropump (100) that utilizes electro-osmotic pumping of fluid in one channel or region (106) to generate a pressure based flow of material in a connected channel (104), where the connected channel (104) has substantially no electro-osmotic flow generated. Such pumps have a variety of applications, and are particularly useful in those situations where the application for which the pump is to be used prohibits the application of electric fields to the channel in which fluid flow is desired, or where pressure based flow is particularly desirable.

Cette invention se rapporte d'une façon générale à une micropompe (100) qui utilise le pompage électro-osmotique de fluide dans un canal ou une région (106), afin de produire un flux de matière par pression dans un canal (104) raccordé, lequel ne contient aucun flux électro-osmotique généré. Ces pompes ont une grande variété d'applications et elles sont particulièrement utiles dans les situations où l'utilisation pour laquelle la pompe est prévue empêche l'application de champs électriques dans le canal dans lequel un flux de fluide est souhaité ou dans lequel la création d'un flux par pression est particulièrement souhaitable.
