Reagent Mixer and Fluid Control Devices

摘要

An apparatus for preparing a reagent solution includes an enclosure and a container disposed within the enclosure. The container defines an internal cavity having a compressible volume and defines a passage providing fluidic communication between the internal cavity and the exterior of the container. Optionally, a compressible member is disposed within the internal cavity. A reagent is disposed within the internal cavity.

主权项

1. A method of preparing a reagent solution, the method comprising:
providing a plurality of enclosures within a volume of a cartridge, the cartridge including a gas port, and the enclosure including:
a container disposed within the enclosure, the container defining an internal cavity and defining a passage providing fluidic communication between the internal cavity and the exterior of the container; anda reagent disposed within the internal cavity; filling the enclosure with a fluid through a fluid port of the enclosure; increasing a gas pressure of the volume of the cartridge via the gas port to pressurize the fluid within the enclosure, the fluid flowing into the internal cavity of the container and compressing the compressible volume; and decreasing the gas pressure of the volume of the cartridge via the gas port to depressurize the fluid within the enclosure, the compressible volume decompressing and ejecting the fluid and reagent from the internal cavity, the reagent mixing with the fluid.
