First Claim
1. A fluid control and processing system comprising:
- a cartridge;
a cylinder body being received in the cartridge, said cylinder body comprised of a cylinder and a fluid port in fluid communication with said cylinder;
a piston movable in the cylinder to modulate a fluid volume inside said cylinder;
an instrument for operating the cartridge, said instrument including;
a piston driver for driving the piston, androtating means including a cylinder driver for rotating the cylinder body around an axis A which extends along the piston driver;
dispensing ports to drive at least a fluid flow, each dispensing port being positioned to be connectable, when the instrument is operating the cartridge, with the fluid port by rotation of the cylinder body; and
reversible fastening means for fastening the piston to the piston driver so that movement of the piston is controlled by the piston driver, wherein the reversible fastening means fastens the piston to the piston driver when the instrument rotates the piston driver with respect to the piston in a first direction around the axis A, and unfastens the piston from the piston driver when the instrument rotates the piston driver with respect to the piston in a second direction opposite to the first direction.

Abstract
A fluid control and processing system comprising a cartridge and an instrument for operating the cartridge. The cartridge comprises a cylinder body comprising a cylinder and a fluid port. It further comprises dispensing ports to drive a fluid flow, each dispensing port being positioned to be connectable, when the instrument is operating the cartridge, with at least a fluid port by rotation of the cylinder body. The instrument comprises a piston driver for driving the piston. The system further comprises: reversible fastening means for fastening the piston when the piston driver is rotated with respect to the piston, so that the movement of the piston is controlled by the piston driver; and rotating means comprising a cylinder driver constitutive of the instrument for rotating the cylinder body around the axis A.

11. An instrument comprising:
- a piston driver defining an axis A which extends along the piston driver, and a cylinder driver;
wherein said instrument is used in a fluid control and processing system including;
a cartridge operated by the instrument;
a cylinder body being received in the cartridge and arranged to be rotated by the cylinder driver around the axis A, said cylinder body comprising a cylinder and a fluid port in fluid communication with said cylinder;
a piston movable in the cylinder to modulate a fluid volume inside said cylinder, said piston driven by the piston driver;
dispensing ports to drive at least a fluid flow, each dispensing port being positioned to be connectable, when the instrument is operating the cartridge, with the fluid port by rotation of the cylinder body;
reversible fastening means for fastening the piston to the piston driver so that movement of the piston is controlled by the piston driver, wherein the reversible fastening means fastens the piston to the piston driver when the instrument rotates the piston driver with respect to the piston in a first direction around the axis A and unfastens the piston from the piston driver when the instrument rotates the piston driver with respect to the piston in a second direction opposite to the first direction.
