Abstract

Micro válvulas de retención con una flotación libre para el control de los flujos de líquido en aplicaciones de microfluídos y biomédicas y sus métodos de fabricación. Una microválvula incluye un asiento de la válvula, una tapa de la válvula que pone en contacto con el asiento de la válvula flotante y un miembro sin ataduras que puede moverse entre el asiento de la válvula y la tapa de la válvula. Algunas microválvulas tienen apertura con cero o poca presión y no flujo reverso. Algunos otros tipos de válvulas pueden ser configuradas para permitir el flujo de líquido dentro de un rango de presiones. El miembro flotante puede ser sólido o definir un orificio, y el asiento de la válvula puede tener uno o dos niveles. Estas Válvulas pueden ser configuradas para permitir el flujo de líquido cuando el miembro flotante es empujado por el fluido contra la tapa de la válvula o en contra del asiento de la válvula. El asiento de la válvula puede ser de silicio u otro material que sea compatible con los micro-procesos, la tapa de la válvula y el miembro flotante pueden ser de un polímero como Parylene.
