When the predetermined time has elapsed (YES), the process proceeds to step S30, and the abnormality detection unit 45 measures the blood collection amount of the blood collection bag 200 for the second time. After that, the process proceeds to step S32, and the abnormality detection unit 45 calculates the blood collection amount (blood collection rate) based on the increase in the blood collection amount per hour.

After that, in step S34, the abnormality detection unit 45 determines whether or not the blood sampling amount detected in step S32 is less than the reference value of the predetermined value. For example, if the blood collection volume is reduced to the extent that the specified amount of blood collection is not completed within 20 minutes, some abnormality may occur in the collected blood. Therefore, the abnormality detection unit 45 causes the blood collection volume to decrease. Detects abnormalities during blood collection. When the abnormality detection unit 45 detects a decrease in the blood collection volume in step S34 (YES), the control unit 43 proceeds to step S36 and records the abnormality information at the time of blood collection due to the decrease in the blood collection volume in the blood collection data. .. Further, in step S36, the control unit 43 displays a warning on the blood collection screen 78 of the display input unit 38, and prompts the operator to take measures such as changing the suction pressure setting.

Here, when any of the abnormality of the swing mechanism 20 of the blood collection device 10, the abnormality of the exhaust pump 24, the abnormality of the power supply voltage, and the pressing of the stop switch 40 by the operator is detected by the abnormality detection unit 45, It is determined that an error has occurred (YES), and the process proceeds to step S44. In step S44, the control unit 43 records in the blood collection data that the blood collection has been halfway due to the occurrence of an error. On the other hand, if no error is detected in step S42 (NO), the process returns to step S28.

The blood collection device 10 determines the end of blood collection in step S20 of FIG. 4 at regular intervals. In step S20, when any of the conditions of when an abnormality (error) is detected in step S38 or step S42 of FIG. 5 and when the blood collection amount of the blood collection bag 200 reaches the specified value is satisfied. The control unit 43 determines (YES) that the blood collection is completed.

On the other hand, in step S20, if the error in step S42 is not detected and the blood collection amount of the blood collection bag 200 does not reach the specified value, the control unit 43 determines (NO) that the blood collection is not completed. , Return to step S16 and continue blood collection. The blood collection screen 78 updates the display contents such as the remaining amount display of the blood collection remaining amount display unit 78e (see FIG. 6) as the blood collection progresses.

If it is determined (YES) to end blood collection in step S20, the process proceeds to step S22. Then, in step S22, the time measuring unit 44 of the control unit 43 detects the blood collection end time and records the blood collection end time in the blood collection data. Further, in step S22, the abnormality detection unit 45 obtains the required time for blood collection based on the blood collection start time and the blood collection end time, and if it exceeds the predetermined reference time, it is considered that an abnormality has occurred at the time of blood collection and the blood collection data is recorded. Record abnormal events.

After that, in step S24, the control unit 43 stops the swing mechanism 20 and the exhaust pump 24, and opens the accommodation chamber 12 to the atmosphere. In addition, the control unit 43 records the completion of blood collection in the blood collection data.
