[Detailed description of the invention]

[0001]

The present invention provides a platelet storage bag used for separating platelets from plasma collected from a blood donor and storing the platelets.

[0002]

2. Description of the Related Art At present, when platelets are separated from plasma collected from a blood donor and stored, after centrifugation of the plasma to precipitate the platelets, only the plasma components from which the platelets have been separated are separated. Transfer to plasma component separation bag via connecting tube. At that time, a certain amount of plasma is left or a blood plasma substitute is introduced to resuspend the platelets settled in the bag.

However, when the platelets are resuspended, a connecting tube is connected to the bag in which the platelets from which the plasma components have been separated remain, and the plasma substitute solution (physiological saline) (or platelet storage) is connected through the connecting tubes. Since the liquid is introduced into the bag, there is a risk of contamination by bacteria in the air when the connecting tube is connected, which is not preferable for sanitation.
In addition, since a certain amount of plasma is left, the amount of recovered plasma is lost when viewed in total, which is not preferable. Therefore, the present inventors have made intensive studies to solve the above problems, and have arrived at the following invention.

[0004]

According to the present invention, the rear end of the sampling tube 5 having the connector 15 attached to the tip and the tip of the connecting tube 6 are connected to the upper end of the sampling bag 2, respectively. A storage solution supply bag filled with a plasma substitute solution or a platelet storage solution via a connection tube 10 in which a connection tube 7 is connected to a rear end of the connection tube 11 via a connection tube 11 and a communication piece 13 is disposed on the connection tube 11 on the way. 14
And a connecting pipe 12 is connected downstream of the connecting tube 7.
Then, the connecting tube 12 is connected to the connecting tube 12 via the connecting tube 9 (8).
Stores plasma components obtained by separating platelets from the blood collection bag 2
To provide a platelet storage bag 1 to which one or more plasma component separation bags 3 (4) are connected.

[0005]

FIG. 1 is a schematic view of a platelet storage bag 1 according to the present invention. A platelet storage bag 1 is provided with a sampling tube 5 provided with a connector 15 connectable to another tube, a bag or the like at the upper end of a bag body made of a flexible synthetic resin; One or more blood component separation bags 3, 4 for storing plasma components from which platelets have been separated in the bag 2, and storage in which a plasma substitute solution (physiological saline solution) (or platelet storage solution) is filled inside the bag body. It is composed of a liquid supply bag 14.

Each of the blood collection bag 2, the plasma component separation bags 3, 4 and the preservation solution supply bag 14 is formed by laminating two flexible synthetic resin sheets and welding them to form a bag, or blow molding. The end is welded to form a bag.

[0007] The above-mentioned blood collection bag 2, plasma component separation bags 3, 4 and storage solution supply bag 14 are connected tubes 6, 7, 8, 9, 10 and connection tubes 11, 12 mounted on the upper end of each bag. Are connected via A communication means such as a communication piece 13 is provided in the middle of the connection tube 10.
Have been . Connection of blood collection bag 2 and blood component separation bag 3
Connecting tube arranged in the middle of tube 6 and connecting tube 7
11 through the connecting tube 10 to the storage solution supply bag
14 are connected.

At the upper end of the bags 2, 3, and 4, a blood transfusion port (transfusion port) 17 is mounted on the protector 16 while being covered.

Next, a method of using the platelet storage bag 1 will be described. The connector 15 is connected to a bag or the like attached to the bag or a bag or the like in which whole blood is separated into plasma and blood cell components, and the upper layer of plasma is passed through the sampling tube 5 and the main body of the sampling bag 2. Introduce within. After arbitrary portions of the collection tube 5 and the connection tube 6 are closed with a clamp or the like to seal the collection bag 2, the plasma is subjected to centrifugation to separate platelets and plasma components . The clamp of the connection tube 6 is opened, and the plasma component from which platelets have been separated is stored in the separation bag 3 via the connection tubes 6, 7, and 9. Further, the plasma in the separation bag 3 is connected to the connecting tube 8.
By transferring to the separation bag 4 connected by the above, the amount of plasma in the separation bags 3 and 4 can be adjusted, so that it is easy to comply with the specification of the plasma preparation.

Subsequently, an arbitrary portion of the connecting tube 7 is heat-welded to separate the connecting tube 7 from the blood collection bag 2, the communication piece 13 is broken, and the plasma substitute solution (physiological saline) (or platelet) is removed from the storage solution supply bag 14. The preservative solution) is introduced into the blood collection bag 2 via the connecting tubes 10 and 6, and is mixed with the sedimented platelets.

[0011]

[Operation and effect of the present invention] As described above, the present invention
Since the plasma substitute solution or the platelet preservation solution can be supplied in a completely closed system, platelets are not contaminated by bacteria in the air and are sanitary. Since the plasma for resuspending platelets can be replaced with a plasma substitute solution or a platelet preservation solution, the amount of plasma for plasma preparations to be collected is increased.
