A medical device for separating a fluid, in particular for separating platelet-rich plasma from whole blood, includes three containers and at least one corresponding connection line having an intermediate bifurcation. Provided on the connection line are valve means for enabling or preventing a flow of fluid. At least one container includes a hollow container body and a plunger associated in a movable way to the container body. The device also includes a filtering member on the connection line.

Methods and systems for sampling blood components in a photopheresis procedure are disclosed. The methods include collecting samples at selected times during a photopheresis procedure.

A blood component separation device for separating a plurality of blood components from blood sampled from a blood donor, and collecting platelets, includes: an operation unit that calculates a predicted platelet recovery rate from a hematocrit value of the blood and a platelet concentration of the blood, and calculates a recommended processing amount of the blood recommended for collecting a target number of units of platelets on the basis of the calculated predicted platelet recovery rate, wherein the operating unit sets the predicted platelet recovery rate calculated from any the hematocrit value and any the platelet concentration to be smaller by a predetermined value a when the blood donor is female than that when the blood donor is male.

A medical device for separating a fluid, in particular for separating platelet-rich plasma from whole blood, includes three containers and at least one corresponding connection line having an intermediate bifurcation. Provided on the connection line are valve means for enabling or preventing a flow of fluid. At least one container includes a hollow container body and a plunger associated in a movable way to the container body. A modular structure has modules connected to enable separation thereof. A first module includes at least the first container and a corresponding portion of the first connection line, and a second module, which has at least one between the second and third containers with a corresponding portion of the first connection line. Provided at least at the interface between two modules of the modular structure are releasable connectors, in particular hydraulic connectors having at least two parts that can be coupled together, each of which belongs to a corresponding module.

A blood sampling device (10) configuring a blood bag system (12) includes: a hollow needle (80) that can penetrate through a rubber plug (202) of a blood sampling tube (200) inserted into a blood sampling holder (78); a hub (76) that includes a needle supporting unit (90) for supporting a base end side of the hollow needle (80) and to which the blood sampling holder (78) is rotatably attached; a needle cover (82) made of rubber that is externally fitted to the needle supporting unit (90) while covering a tip side of the hollow needle (80); and a cap (84) arranged on the needle supporting unit (90) in such a manner that the cap (84) can come into contact with the needle cover (82) and is independent of the blood sampling holder (78).

A blood component separation device for separating a plurality of blood components from blood sampled from a blood donor, and collecting platelets, includes: an donor calculation unit that calculates a predicted platelet recovery rate from a hematocrit value of the blood and a platelet concentration of the blood, and calculates a recommended processing amount of the blood recommended for collecting a target number of units of platelets on the basis of the calculated predicted platelet recovery rate, wherein the operating unit sets the predicted platelet recovery rate calculated from any the hematocrit value and any the platelet concentration to be smaller by a predetermined value when the blood donor is female than that when the blood donor is male.

A blood treatment filter includes a housing having a first resin sheet and a second resin sheet, a filter member disposed in the housing, a peripheral edge molded body formed on a peripheral edge portion of the filter member and having an inner peripheral portion joined to an outer peripheral end edge of a filtering material, and a connection sheet extending outward from the peripheral edge molded body and connected to the housing.

Systems and methods for the washing of biological fluid/biological cells are disclosed. The method provides for the automated dilution of the cell feed during the cell washing procedure using a separator in which the separator has a predetermined maximum output concentration for the biological cells that are being washed. The method further includes determining the concentration ratio of the biological cells to be washed in the washing procedure and determining a maximum input concentration as a function of the maximum output concentration and the concentration ratio. Wash solution is then added to dilute said biological cells so that the maximum input concentration of the diluted biological cells entering the separator is not exceeded.

Methods and systems for reducing bacterial contamination of platelets are disclosed. The methods and systems disclosed herein provide for the processing of a pre-determined volume of whole blood so as to reduce the risk that platelets separated and collected from the whole blood have a reduced risk of bacterial contamination.

A tube segment sampler system (10) for withdrawing a fluid sample from a tube segment (100), the sampler (10) having a first tube piercing member (28) for piercing the tube segment at a first location and a second tube piercing member (28) for piercing the tube segment at a second location so as to allow air to be drawn into the tube segment (100) through one of the openings made by one of the piercing members (28) while fluid is withdrawn through the other of the openings.
