Blood collecting apparatus and blood-collecting method using blood collecting apparatus

A white blood cell-removing device has a bag-shaped housing made of soft resin, a white blood cell-removing filter member partitioning the inside of the housing into an inlet side blood chamber and an outlet side blood chamber, a blood inlet port positioned at one side of the housing and communicating with the inlet side blood chamber; and a blood outlet port positioned at the other side of the housing and communicating with the outlet side blood chamber. An inner surface (the outlet side blood chamber) of the bag-shaped housing is a unevenness surface. The white blood cell-removing filter member has a filtering part and a non-filtering part formed on the entire periphery of the filtering part.

White blood cell-removing device, white blood cell-removing apparatus and white blood cell-removing method

A cell storage bag system comprises a storage bag for containing cells to which at least one connecting tube having a closed end is connected, a reservoir container for containing an additive fluid to which a fluid supply tube having a closed end is connected, and a waste fluid container for receiving waste fluid to which a waste fluid tube having a closed end is connected. In the system, the at least one connecting tube is adapted to be connected to the fluid supply tube and/or said waste fluid tube by means of a tube connecting apparatus in a sterile manner, and when the connecting tube is connected to the fluid supply tube, the additive fluid is supplied to the reservoir bag through these connected tubes, and when the connecting tube is connected to the waste fluid tube, the waste fluid is collected from the storage bag through these connected tubes.

Method of preserving cells using cell storage bag system

This invention concerns an apparatus and a method for the manufacture of blood products which are aimed at attaining the manufacture of blood products automatically and rationally with the operational efficiency enhanced, the quality of blood products stabilized, and the safety of blood products exalted, which are characterized in that the tube of a first container and the tube of a second container are aseptically and automatically connected preparatorily to the transfer of a plurality of blood components obtained by the separation of blood in the first container to the second container and the blood components in the first container are transferred through the connected tubes to the second container by use of a blood component transferring device.

Apparatus for manufacture of blood products and method for manufacture

An apparatus and method for transferring a centrifugally separated component in a liquid contained in a flexible bag is disclosed. The apparatus is composed of a centrifugal container for accommodating flexible blood collecting bag filled with blood, and a pushing mechanism for pushing the blood collecting bag. The pushing mechanism is composed of a pair of rollers for pushing a soft material part of the cylindrical portion of the centrifugal container from opposite directions in such a manner that the soft material part is deformed inwardly to project inside the centrifugal container and increase inner pressure of the flexible bag to transfer separated component out of the flexible bag. According to the apparatus and method, the yield for collecting the separated component obtained by centrifugal separation can be increased, and the time required for collection can be decreased.

Apparatus and method for transferring separated component in liquid from

A composite of interconnected bags comprises a blood collecting bag, a preserving liquid bag, and a blood plasma bag. The interior of the bag body of the blood collecting bag is divided by a partition strip into an empty space and an empty space of the shape of a strip, with the two empty spaces mutually communicating near the end part of the partition strip. The blood collected in the blood collecting bag is centrifuged. The upper layer of blood plasma resulting from the centrifugation is discharged via a tube to the blood plasma bag. Then, the erythrocyte preserving liquid in the preserving liquid bag is advanced through the tube, the empty space, and a connecting part and added upwardly from below to the concentrated erythrocyte left behind the empty space. The erythrocyte preserving liquid, without being stirred, is allowed to ascend and mingle with the concentrated erythrocyte with the elapse of time. Thus, the present invention provides a erythrocyte preparation excellent in quality and fee from occurrence of floccules.

Method for treatment of blood using a blood bag

A container device comprises a blood-collecting bag, a platelet conserving bag, and a plasma bag. These bags are connected each other by tubes. Anticoagulant agent is contained in the blood-collecting bag, and the other bags are empty. The blood-collecting bag is formed of flexible polyvinylchloride. The blood-collecting bag is autoclaved after containing anticoagulant. The other bags are formed of polyolefin such as EVA, and radiation- or gas-sterilized in an empty state.

Medical container device and method for manufacturing same

A blood collection device having a blood-collecting tube, a needle, a blood container connected to the needle by the blood-collecting tube. The blood container has a blood-storing space containing anticoagulant solution. Two blood-component containers and an erythrocyte-preserving solution container are connected to the blood container by a blood-component supplying tube and a tube. The containers are made of soft material. A branching member is coupled to the blood-collecting tube and located between the blood container and the needle. A tube branching from the blood-collecting tube is connected to a filter. The filter allows passage of gas but substantially prevents passage of blood, bacteria, microorganism and the like. A flow stopper connects the blood-collecting tube to the filter. The flow stopper comprises a breakable member closing the branch tube. When the breakable member is broken, the branch tube communicates with the filter.

Blood collection device

A method for separating liquid components which have been fractionated into at least an upper layer component and a lower layer component in a soft flexible container provided with a liquid transfer port located either at an upper part or a lower part of the container comprising a step of pressing the container to a flat configuration, so as to flowing out one of the liquid components through the liquid transfer port, characterized in that the inner walls of a liquid storage chamber of the flexible container, except for the liquid transfer port, are partly brought into close contact with each other in advance, so as to define such a flowing passage for the liquid component, the width of which becoming narrower toward the liquid transfer port, prior to the step of pressing the flexible container to a flat configuration.

Method for producing vinyl chloride resin products

A blood bag of the present invention comprises a blood collection container; a tube communicating with the blood collection container and provided with a blood collecting needle at its distal end; and a blood collecting tube receiving member attached to the tube detachably or movably along the tube. Before labels are stuck on, a blood collecting tube into which blood has been collected from this blood bag is not confused with another blood collecting tube into which blood has been collected from another blood bag, or after labels are stuck on, blood is not collected from another blood bag into a blood collecting tube in which has been stuck a label having the same as serial number as a label stuck on this blood bag, so as to avoid a danger that blood having an infectious disease is transfused for mistaking it for safe blood.
