A recently granted patent (Publication Number: US11927600B2) discloses a disposable cartridge designed for processing a single fluid sample for biological analysis. The cartridge features multiple interconnected chambers within a housing, a moveable valve body for fluid processing, and an elongated fluidic bridge with fluid channels for transporting the sample to another device. The bridge extends outside the cartridge receiver, allowing the processed sample to be transported to a separate device for further analysis. Additionally, the cartridge includes sample processing chambers, such as an amplification chamber, to facilitate biological analysis efficiently.

Furthermore, the patent describes a module for sample preparation comprising a sample processing cartridge, a cartridge receiver, and a fluidic bridge. The cartridge receiver includes units for moving the valve body and applying pressure to process the sample within the cartridge. The fluidic bridge, elongated and with fluid channels, facilitates the transport of the prepared sample from the cartridge to an assay processing device. The system also includes a first sample processing device, a second independent processing device, and a fluidic bridge to transport the sample between the devices, enabling efficient biological analysis. The fluidic bridge can couple with different sample processing devices, offering flexibility in the analysis process.
