Device for dispensing microbeads for cell sonoporation

A device for dispensing microbubbles for cell sonoporation, wherein the device comprises:

• a tube symmetrical about a vertical axis, said tube being configured to receive a vial containing a solution of microbubbles,
• at least two catheters arranged inside the tube, said catheters being at least partially oriented substantially parallel to the vertical axis, each of the catheters having at a first end an orifice adapted to open into the vial when the latter is received by the tube, the first catheter being adapted to be connected to a first air injection source, the second catheter having a second end,
• wherein, when the first catheter is connected to the first air injection source, air can be injected into the vial via the orifice of the first catheter, the injected air generating an overpressure in the vial, so that microbubbles contained in the vial enter the second catheter via the orifice of its first end, and then move inside the second catheter toward its said second catheter's second end.
