摘要:
A blood bag system includes a BC pooling bag for centrifugation of a buffy coat, a filter for removing white blood cells from a supernatant liquid transferred from the BC pooling bag, a platelet preserving bag for reserving the supernatant liquid that has passed through the filter, a first tube connecting the BC pooling bag and an inlet of the filter, a second tube connecting the platelet preserving bag and an outlet of the filter, and a cassette to be fixed in the centrifugation and separation apparatus. The first tube and the second tube are disposed within the cassette. The cassette includes a first clamp section for closing and opening the first tube, and a second clamp section for closing and opening the second tube.

The invention provides a filtering and centrifugation device, comprising a barrel, a volume in the barrel for receiving a fluid sample to be processed, a filter medium, at least one piston movable in the barrel to force fluid in the volume through the filter medium to produce a filtrate, and a space for pelleting particulate material. The device is centrifugeable, and said space is located in or communicates with the volume and is located preferably away from the filter medium such that the particulate material does not or at least not completely clog the filter medium during such centrifugation of the device. The invention also provides a method for the sterile filtration of a sample, comprising the steps of introducing the sample into the volume of such a device, subjecting the device to centrifugation to pellet particulate material contained in the sample at the space away from the filter medium, and applying force to the piston(s) to force fluid of the sample in the volume through the filter medium to produce a filtrate. By providing the space for pelleting the particulate material under the influence of the centrifugation force, the clogging of the filter medium can be avoided or considerably delayed. Further, the entire process can be performed in the same device without having to remove the sample for any intermediate clarification steps.

Adapter for inserting a sample container in a centrifuge bucket, comprising a bucket-like base body, which delimits a cavity for accommodating said sample container and has a bottom region and an adjoining side wall region, the top edge of which defines an opening edge of said cavity, and an insertion opening, through which said sample container can be inserted in said cavity and which is delimited by said opening edge, at least one separation joint being present in said side wall region of said base body, which separation joint extends from said opening edge in the direction towards said bottom region and which allows for expanding said side wall region from a starting position (P1) to an expanded position (P2) by applying a force in such a way that said opening edge has a larger circumference as compared to the starting position (P1). Said side wall area has two edge regions separated from each other by said separation joint, which at least in the starting position (P1) lie one above the other radially and overlap in the circumferential direction (U), thus forming an overlap region.

The present invention provides a centrifugal separation-use device capable of maintaining a centrifugal separation-use container in a clean state easily at low cost even when centrifugal separation treatment is carried out using a centrifugal separator in an unclean field. A centrifugal separation-use device 1 for collecting a target component by subjecting a solution containing multiple components to centrifugal separation treatment comprises an inner container 10 having a cylindrical section 12 for accommodating the solution and a plug 14 for hermetically sealing the cylindrical section and configured so as to accommodate the solution in a hermetically sealed state, and an outer container 20 having a support section 22 for removably accommodating the cylindrical section and a delivery section 24 for exposing part of the inner container so that the inner container can be removed, and configured so as to accommodate the inner container in a hermetically sealed state.
摘要:
An apparatus and method for collecting whole blood and then separating it into components for subsequent use or storage. A self-contained bag set is used to collect the sample, which may then be placed into a device adapted to fit into a centrifuge for separation of components. Each component is then sequentially extracted according to density, with a sensor present in the device to control the operation of valves directing the collection of each component. The sensor may be reading one or more of the following characteristics: infrared, optics, density, weight, radioactive, fluorescence, color, magnetism, ultrasonic, capacitance wherein the characteristic is inherent in the blood and blood component or is an additive. Each component may then be separated into its own storage container. The preferred sensors include optics and weight. Besides blood density separation, the device may contain a solution including cells, proteins, subcellular particles or viruses which may be mixed with affinity media or antibodies prior to separation.

A method for the cell separation from blood or from blood products, having the following steps: (i) inserting a blood bag (35) containing a blood product into a blood bag section (5) of a cartridge (1) (ii) inserting a tube (36) connected to the blood bag (35) into a product transport path (36) which connects the blood bag (35) to a product bag (33) wherein a first sensor (25) and a second sensor (85) are positioned along the product transport path (36), (iii) inserting the cartridge (1) into a rotor of a centrifuge, (iv) spinning the centrifuge for separating the individual blood components, (v) transporting a predetermined quantity of a blood component along the product transport path (36) at a first flow speed, (vi) detecting the composition of the transported blood component by the first sensor (25). The second sensor (85) also detects the composition of the transported blood component after the first sensor (25) has output a signal corresponding to a predetermined composition of the blood component. The transporting and the spinning are terminated when the second sensor (85) detects the predetermined composition and outputs a respective end signal, or when a predetermined period of time has elapsed.
