2. Description of the Related Art Infections caused by allogeneic blood transfusion (hepatitis, AID)
In recent years, autotransfusion has attracted attention in order to prevent immunological side effects. Among these autologous blood transfusions, blood-collecting autologous blood transfusion is used to collect blood from a patient (blood donor) himself before surgery and store the blood in a blood bag for a patient who needs blood transfusion during surgery. A blood bag is stored in a storage container in a refrigerated or frozen state, and at the time of surgery, a blood bag containing the patient's blood is removed from the storage container and the blood is transfused.

[0003] In this case, in order to secure a sufficient transfusion amount, blood is usually collected from a patient a plurality of times. Also, due to the limitation of the blood storage period, it is also possible to return the stored blood (for one bag) once to the patient on the previous blood collection date, collect blood twice as much as that (for two bags), and store it. Done.

[0004] In such a blood storage type autologous blood transfusion,
Usually, the blood of a plurality of patients is stored at the same time, and it is possible that the blood bag of another patient may be mistaken for a blood transfusion or blood return, but this should not be the case. Therefore, when the blood bag is taken in and out a plurality of times, great care must be taken each time.

[0005] In order to prevent mixing of blood bags,
Conventionally, the following method has been adopted.

[0006] The patient signs by hand on the label of the blood bag, which the patient or his family sees and confirms before transfusion.

A dedicated storage box is provided for each patient, and the collected blood bag is stored in the patient's storage box.

[0008] A segment (a short tube for sampling) is provided in the blood bag, and a cross-match test is performed using the sample blood in the segment before transfusion.

However, in the above-described method, since the consistency between the patient and the blood bag is confirmed depending on human judgment, there is a possibility that an erroneous judgment may be made. You may not be able to do so, or you may neglect these procedures. Further, in the above method, there is a possibility that the blood bag is mistakenly placed in the storage box or that the storage box itself is mistaken for another patient.

In the above method, although the blood type can be confirmed, the blood may be blood of another patient of the same blood type. In this case, the purpose of autologous blood transfusion (infection and Prevention of clinical side effects) cannot be achieved. As described above, at present, a method for easily and surely preventing the mixing of blood bags has not yet been established.

For example, the identification member carried by the patient (blood donor) is not limited to a card or a card-like member, and may be, for example, a name tag, a chart, or another display carrier.
Fingerprints, handprints, and other characteristics that can represent patient-specific characteristics may be used.

As the information carrier attached to such an identification member, a black and white mosaic pattern such as a color code may be two-dimensionally displayed in addition to a one-dimensional code such as the bar code described above. The arranged two-dimensional code can also be used. In this case, as the reading device,
For example, a two-dimensional reading device using an area sensor (CCD) is used.

Furthermore, a magnetic recording medium, a magneto-optical recording medium or an optical recording medium can be used as the information carrier. When the information carrier is attached to an identification member, it is formed in a stripe shape (track shape). In this case, a reproducing device having a magnetic head and an optical head (optical pickup device) is used as the reading device.

The label manufacturing machine is not limited to the printer described above, but may be any machine capable of forming an information carrier on a label. For example, if the information carrier is a magnetic recording medium, the label maker is a magnetic recording device that writes information about the patient on the magnetic recording medium on the label.

Further, the locking mechanism is not limited to the above-described electronic lock device, but may be a mechanical locking mechanism. In this case, when it is confirmed that the barcodes match, permission to unlock the storage container is notified by, for example, a voice or a display, and the lock is artificially opened in accordance with the notification. .

In the configuration shown in the figure, the control device
The reading device, the label manufacturing machine, and the locking mechanism are connected by cables, respectively, but may be configured to wirelessly communicate with each other.

Further, the application of the present invention is not limited to the above-mentioned autologous blood transfusion, but may be used, for example, for collation of blood type or the like at the time of allogeneic blood transfusion.

[0107]

As described above, according to the blood bag management method of the present invention, it is possible to surely prevent the blood bags from being mixed up. In particular, when the present invention is applied to the management of a blood bag at the time of blood storage type autologous blood transfusion, the blood of another patient will not be inadvertently transfused, and when part of the stored blood is exchanged. In addition, the blood bag can be easily managed.

In particular, when the information carrier affixed to the label attached to the blood bag has, as additional information, information on the number of times of blood collection or the date and time of blood collection, when performing a partial exchange of stored blood, It is possible to easily and properly select a blood bag to be replaced, that is, a blood bag containing the oldest blood.
