Microfluidic system with cartridge and container for chemicals
The granted patent US12042793B2 describes a microfluidic system designed to facilitate the handling and mixing of dry chemicals within a controlled environment. The system comprises a cartridge featuring an opening and multiple microfluidic channels connected to one or more chambers. A key component is a container that is specifically designed to hold dry chemicals and can be inserted into the cartridge's opening. This container has a housing with two openings: a larger first opening and a smaller second opening. The design ensures that the container fits securely within the cartridge without any fluid leakage, allowing for effective fluidic coupling with the microfluidic channels through the smaller opening. Additionally, the system includes a lid that seals the first opening of the container, featuring a seal structure that presses against the inner wall of the housing and a column extending into the container's central chamber.
Further details of the microfluidic system include the container's housing, which consists of two cylindrical portions, with the first being larger than the second. The diameters of these portions are designed to match the respective openings of the container and cartridge. The container may also have protruding structures that help secure it within the cartridge, which can align with corresponding indentations in the cartridge. The column of the lid is designed to contact the dry chemicals, preventing them from becoming dislodged, and may feature a rounded or conical tip. Notably, the dry chemicals can include freeze-dried reagents, enhancing the system's utility in various applications involving precise chemical handling and mixing.
