Patent ID: 7959876

Claim:
A fluidic device comprising a first reservoir to receive a first fluid; a second reservoir to receive a second fluid; a main channel coupled to the first and second reservoirs through one or more branch channels, wherein a valve having a connector is disposed in one of the branch channels and the valve couples the main channel with the second reservoir, wherein when the connector is intact, the valve prevents the second fluid from entering the main channel, and when the connector is broken, a passage is generated to allow the second fluid to enter the main channel; a first one-use pump, connected to the main channel, the first one-use pump comprising a first main body with a first channel configured therein, in which at least a part of the first main body is made of a first elastic material; and a first container, being disposed inside the first channel of the first main body near a part of the main body made of the first elastic material, wherein a material of the first container is a first brittle material, wherein a first pressure difference is generated in the first channel of the first main body of the first one-use pump when a body of the first container is broken into physically separated pieces, and a portion of the first fluid is moved from the first reservoir to a first position at the first main channel due to the first pressure difference, and at the same time the connector of the valve is intact; and a second one-use pump, comprising a second main body with a second channel configured therein, in which at least a part of the second main body is made of a second elastic material; and a second container, being disposed inside the second channel of the second main body near the part of the second main body made of the second elastic material, wherein a material of the second container is a second brittle material, wherein a second pressure difference is generated in the second channel of the second main body of the second one-use pump when a body of the second container is broken into physically separated pieces, the portion of the first fluid is moved from the first position at the main channel to a second position due to the second pressure difference and the second fluid is drawn from the second reservoir when the connector of the valve is broken and is moved toward the second position after the portion of the first fluid due to the second pressure difference.
