FLUID DISPOSING SYSTEM AND CENTRIFUGAL SEPARATION METHOD USING THE SAME
A fluid disposing system includes a centrifugal separator that centrifugally separates a liquid that is supplied, a reagent injecting apparatus coupled to the centrifugal separator and that injects a reagent into the centrifugal separator, a reagent supply module that supplies the reagent to the reagent injecting apparatus and a pipetting module provided on an upper side of the centrifugal separator and that feeds the fluid to the centrifugal separator.
DETECTION APPARATUS AND DETECTION METHOD
Disclosed is a detection apparatus that transfers magnetic particles through a plurality of chambers in a cartridge which includes the plurality of chambers and a channel connecting between the plurality of chambers, and that causes the magnetic particles to carry a complex of a test substance and a labelling substance, to detect the test substance on the basis of the labelling substance in the complex. The detection apparatus includes: a rotation mechanism configured to rotate the cartridge about a rotation shaft; a magnet configured to collect the magnetic particles in the chambers; a movement mechanism configured to move the magnet in a direction different from a circumferential direction of a circle in which the rotation shaft is centered; a detector configured to detect the test substance; and a controller programmed to control the rotation mechanism and the movement mechanism so as to transfer the magnetic particles from one of the chambers to another one of the chambers.
CENTRIFUGAL SEPARATION APPARATUS AND CENTRIFUGAL SEPARATION METHOD
According to an embodiment, a centrifugal separation apparatus includes, a centrifugal separator comprising a retainer and a rotating member for rotation of the retainer, the retainer adapted to retain a workpiece, an imaging unit configured to acquire a detection image of an installation position at which the retainer is placed, a transfer mechanism configured to move the workpiece into the centrifugal separator, and a sensor processing unit configured to detect, based on the detection image acquired after an installation process of placing the workpiece into the retainer and before a rotation process of rotating the rotating member, a state of the workpiece subjected to the installation process.
Rotor assembly including a housing for a sensor array component and methods for using same
A rotor assembly includes a rotor plate to rotate around a first axis, a bucket attached to the rotor plate and to rotate around a second axis, and a stop plate to rotate around the first axis between an open position and a closed position. When in the closed position, the stop plate engages the bucket to fix an angular position of the bucket relative to a plane of rotation of the rotor assembly. The rotor assembly further includes a housing for a sensor array component, the housing disposed in the bucket and including a solution inlet, a solution outlet, a transfer basin, a solution retainer disposed between the solution outlet and the transfer basin, and a collection reservoir in fluid communication with the transfer basin. The solution inlet and the solution outlet to engage ports of a flow cell of a sensor array.
FLUID SUPPLY APPARATUS FOR CENTRIFUGE
A fluid supply apparatus for a centrifuge, which supplies a fluid to a centrifuge chamber of the centrifuge is provided. The fluid supply apparatus includes a nozzle unit configured to supply the fluid, a nozzle moving unit movable between an inside or an outside of the centrifuge, a nozzle receiving unit to supply the fluid to the centrifuge chamber by seating the nozzle moving unit, and a fixing unit coupled to the nozzle moving unit such that the nozzle moving unit is movable, and fixed to the centrifuge.
Method for capturing specific cells
The present invention provides a method for capturing specific cells (e.g. many types of cancer cells, including cancer cells not expressing EpCAM), and a method for analysis of specific cells involving the method. Included is a method for capturing specific cells present in blood or biological fluid, the method including: agglutinating blood cells in sampled blood or biological fluid; centrifuging the resulting blood or biological fluid; and then capturing specific cells therefrom onto a hydrophilic polymer layer.
Centrifugal processing unit including a blocking element
A centrifugal processing unit for directing the movement of substances within a sample processing cartridge, the centrifugal processing unit having a rotor at least one accommodation for receiving the sample processing cartridge, and a rotor drive for rotating the at least one rotor about a respective rotor axis to create the centrifugal force. The centrifugal processing unit has a blocking element allowing the free pivoting motion of the at least one accommodation in a release position when the rotor is rotated in a first direction and preventing the free pivoting motion in a blocking position, when the rotor is rotated in the opposite direction.
MATERIAL TRANSFER DEVICE AND METHOD OF USE THEREOF
The transfer systems, devices, kits, and methods described here may be used to facilitate the transfer of a material (e.g., a fluid) to or from a donor container, e.g., to or from wells of a donor plate while leaving target agents attached to the wells. The systems may comprise a donor plate, a transfer adapter, and a receiver plate that may be coupled to form a transfer assembly. The transfer adapter may comprise a planar sheet and a plurality of openings, and it may be configured to regulate the flow of fluid out of the wells. The transfer assembly may be placed into a centrifuge, and the fluid transfer force produced by the centrifuge may cause fluid to flow out of the wells of the donor plate, through the openings in the transfer adapter, and into the receiver plate.
Methods and apparatus adapted to quantify a specimen from multiple lateral views
A model-based method for quantifying a specimen. The method includes providing a specimen, capturing images of the specimen while illuminated by multiple spectra at different nominal wavelengths, and exposures, and classifying the specimen into various class types comprising one or more of serum or plasma portion, settled blood portion, gel separator (if used), air, tube, label, or cap; and quantifying of the specimen. Quantifying includes determining one or more of: a location of a liquid-air interface, a location of a serum-blood interface, a location of a serum-gel interface, a location of a blood-gel interface, a volume and/or a depth of the serum or plasma portion, or a volume and/or a depth of the settled blood portion. Quality check modules and specimen testing apparatus adapted to carry out the method are described, as are other aspects.
Systems and methods for sample use maximization
The present invention provides systems, devices, and methods for point-of-care and/or distributed testing services. The methods and devices of the invention are directed toward automatic detection of analytes in a bodily fluid. The components of the device can be modified to allow for more flexible and robust use with the disclosed methods for a variety of medical, laboratory, and other applications. The systems, devices, and methods of the present invention can allow for effective use of samples by improved sample preparation and analysis.
