A method and apparatus are provided for processing a nucleic acid. The apparatus includes a disposable self-contained processing module that contains the nucleic acid and substantially all of the fluids to effect a nanoparticle hybridization test, a pump coupled to the processing module, a valving system disposed between the pump and processing module and a control system coupled to the pump and valving system causing the processing fluids to interact with the nucleic acid to effect a sandwich hybridization test using nanoparticles.

System using self-contained processing module for detecting nucleic acids

A device has processing hardware to carry out a blood processing procedure. A processing control manager resides on the device to monitor status conditions over time during the blood processing procedure. A data interface also resides on the device. The data interface includes a flash memory data storage medium formatted to allocate discrete block file spaces to receive data. Chronologic data or time-specific data are created based upon sensed conditions by a data generator task, which also resides on the device. A file manager task appends chronologic data to an allocated file space to create a chronologic block file, which, when read, provides a time-ordered account of processing activities or hardware conditions. The file manager also operates to block-write time-specific data to another allocated file space, which, when read, creates a snap-shot of processing conditions at a given point in time. The data file structure created on the flash memory medium withstands corruption of data due to power failure.

Systems and methods for storing, retrieving, and manipulating data in medical processing devices

A controller provides an abstract, &ldquo;virtual&rdquo; interface between the software based applications resident in the controller and the hardware elements of the fluid processing system. The controller also provides a straightforward yet very interactive dual region user interface.

Interactive control systems for medical processing devices

A medical fluid processing device for processing blood or other fluids includes a plurality of hardware elements that perform specific functions. Different processing procedures are achieved by performing the specific functions in appropriately arranged sequences and combinations. A user accessible menu permits user selection of the desired processing procedure. A dual region, user accessible screen provides user interaction with the processing device.

A medical fluid processing device for processing blood or other fluids includes a plurality of hardware elements that perform specific functions. Different processing procedures are achieved by performing the specific functions in appropriately arranged sequences and combinations. A user accessible menu permits user selection of the desired processing procedure. A software implemented 'virtual' interface generates appropriate hardware commands for actuating the hardware elements as needed to achieve the desired processing procedure. A dual region, user-accessible screen provides user interaction with the processing device. The 'virtual' interface provides positive control over the individual hardware elements in combination with sufficient system flexibility to achieve useful interactivity with the processing device operator.
