A biological component collection system and a circuit internal pressure acquisition method are provided, which are capable of accurately measuring the circuit internal pressure. A centrifugal separation device of a blood component collection system comprises an estimated data calculation unit that calculates estimated data B on the basis of initial data A, and a correction unit that corrects the estimated data B in a manner so that the internal pressure calculated by a first internal pressure calculation unit becomes equivalent to the internal pressure calculated by a second internal pressure calculation unit.

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.

Provided is a blood filter that resists deterioration in properties as a result of electron beam sterilization treatment performed before or during use as a blood filter, has durability, dimensional stability, and chemical resistance at excellent levels, also has biocompatibility, and resists deterioration in properties even upon the electron beam sterilization treatment. The blood filter according to the present invention includes a nonwoven fabric made of PEEK fibers. Preferably, the blood filter according to the present invention has an average pore size of 3 to 280 m and has a porosity of 15% to 70%; and the PEEK fibers have an average fiber diameter of 10 m or less.

The disclosure provides an apparatus for processing a blood sample, a device for cells preparation and a method thereof. The disclosure can be used for blood separation, cell culture and preparation of cells. The apparatus mainly uses a weight sensor to have the weight and some liquid sensors. By optimizing the connection relationship of each device in the whole equipment, simplifying the operation process of the equipment, coordinating each step of the device, reducing the production cost, integrating the steps of PBMC cell separation and magnetic bead separation, the method makes the cell preparation process more intelligently automated, the operation simpler, the cell pollution reduced and the success rate of cell preparation improved. It has broad application prospects and huge market value.

A sterile solution product bag includes sterilization grade filter integrated directly into the product bag such that microbial and particulate matter filtration can be performed using the filter directly at the point of fill. The filter can include a hollow fiber filter membrane contained in a stem connected to a bladder of the product bag.

A system for wound treatment using a serum, comprising a device for recovering serum from whole blood, comprising: a blood bag for the reception and coagulation of whole blood, which has an outlet for discharging the serum-containing fluid from the blood bag and a barrier in the region of the outlet for retaining the coagulum, a filter module which is fluidically connected to the blood bag and comprises a housing and an interior, in which a semi-permeable membrane is arranged, said membrane dividing the interior into a retentate space and a permeate space and separating the fluid discharged from the blood bag into a permeate comprising the serum and into a retentate in which any particulate components contained in the fluid remain. The system for wound treatment further comprises a wound care system with a capillary membrane system for dispensing the serum to a wound. The capillary membrane system is connected to at least one supply line, which for its part is connected to the permeate outlet of the filter module.

A filter container for separating cells includes a tubular filter member-housing part having an opening at each longitudinal end, a liquid inlet port on a first opening end side of the filter member-housing part, a liquid outlet port on a second opening end side of the filter member-housing part, a first filter-pressing part on the first opening end side, and a second filter-pressing part on the second opening end side. The first filter-pressing part includes three or more first protrusions, and the ratio of an area of a polygon formed by individually connecting the tips of the three or more first protrusions to a cross-sectional area of an inner space of the filter member-housing part at the first protrusion position is controlled within a preset range.

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.

Systems and methods are provided for collecting a platelet product from a fluid including platelets and plasma. Platelet-rich plasma is separated from at least a portion of another constituent of the fluid and then may be further separated into concentrated platelets and platelet-poor plasma, with the concentrated platelets being resuspended. Separated platelets (in the form of platelet-rich plasma or resuspended platelets) are conveyed through a size exclusion filter and into a platelet storage container. The size exclusion filter is configured to remove platelet clumps and/or particles larger than a platelet from the separated platelets. Subsequently, an additive is conveyed through the size exclusion filter and into the platelet storage container. Conveying additive through the size exclusion filter improves platelet recovery in the platelet product by displacement of separated platelets with the additive and may also break up any platelet clumps that are present in the size exclusion filter.
