Abstract
The invention relates to a microfluidic device comprising at least one micro-channel connected at one end to an enclosed area, characterized in that it also comprises an inlet circuit and an outlet circuit connected to the enclosed area and between which the fluid can be discharged without any contact with the micro-channel, wherein at least one of said inlet and outlet circuits can be controlled in such a way that the pressure at the end of the micro-channel can be modified independently from the pressure at the other end of the micro-channel.
Claims22
A pressure monitoring device comprising:
- a chamber configured to be connected at one end of at least one microchannel,
- an inlet circuit in fluid communication with the chamber, and
- an outlet circuit separate from said inlet circuit and in fluid communication with the chamber,
- wherein a substantially continuous flow of fluid can be established from the inlet circuit to a point in fluid communication with said chamber, and from said point to the outlet circuit without contact with the microchannel, and
- at least one of the inlet and outlet circuits comprises a progressively controllable valve so as to control flow rate in the inlet and outlet circuits so as to modify the pressure at said end of the microchannel.
