Patent ID: 8186869

Claim:
A device for the integrated metering and mixing of small quantities of liquid comprising a first reservoir for a first quantity of liquid; a second reservoir for a second quantity of liquid; filling passage structures which are in communication with a reservoir at one respective end and with a filling device at the other respective end; at least two connection passage structures which connect the two reservoirs and have a cross-section at least in one region in the direction of view of the connection line of the reservoirs which is smaller than the cross-sections of the reservoirs; at least one device for the generation of a laminar flow along at least one of said connection passage structures, the at least one device for the generation of laminar flow including a sound wave generation device having at least one radiation direction along at least a part of the at least one connection passage structure; and at least one device for the mixing of the quantities of liquid, the device for the mixing of the quantities of liquid being located in or on the second reservoir.
