In this way, it is necessary to keep the inside of the vacuum blood collection tube at a negative pressure. Therefore, before blood collection, the stopper of the blood collection tube is pulled out and the reaction reagent necessary for the inspection can be put into the blood collection tube. Can not. For this reason, the vacuum blood collection tube is sold in a state in which a reaction reagent or the like is previously placed therein.
As described above, since a reaction reagent or the like is previously placed in the vacuum blood collection tube, the purpose of use is determined for each vacuum blood collection tube, and the type is identified by the color of the stopper of the blood collection tube. .
For this reason, when blood collection is performed using the above-described vacuum blood collection tube, it is necessary to use a vacuum blood collection tube suitable for the purpose of the examination. If the selection of the vacuum blood collection tube is wrong, the collected blood reacts with a reagent that is not related to the test and cannot be used for the test. This is a serious problem when the test is urgent. .
The applicant has already proposed an automatic blood collection tube preparation device that can prevent a selection error of the vacuum blood collection tube and perform reliable blood collection before the examination (see Patent Document 1).
This automatic blood collection tube preparatory device accommodates each blood collection tube in a plurality of blood collection tube storage units, and based on order information from a doctor, from a blood collection tube storage unit in which blood collection tubes necessary for blood collection of a patient are stored A blood collection tube is automatically taken out, a label printed with a patient ID and blood collection information is automatically attached to the taken blood collection tube, and the blood collection tube after labeling is automatically stored in a tray or a bag for each patient.

This automatic blood collection tube preparation device is based on blood collection information and specimen ID determined according to the examination item, in addition to the order number, examination item and patient attribute information included in the order information from the doctor, It is controlled by the control means 30. These pieces of information may all be inputted from a host computer (not shown) such as a host computer. However, the order information from the doctor is directly inputted to the control means 30 via a keyboard or the like, and the inputted order information is converted into the inputted order information. Based on this, the control unit 30 may determine the blood collection information and the sample ID.
Here, “patient attribute information” is patient-specific information such as patient name, patient ID, and / or gender.
“Blood collection information” is information regarding the type and number of blood collection tubes determined according to the examination item. Since the vacuum blood collection tube contains a reactive agent or the like according to the purpose of the inspection in advance, it is necessary to use a blood collection tube according to the inspection item. However, it is not always necessary to use a different blood collection tube for each examination item, and some blood collection tubes can be used in common for a plurality of examination items. For this reason, the type and number of blood collection tubes must be determined according to the examination item.
The “sample ID” is a number that is issued for each blood collection tube, and is associated with the information related to the test item for the blood (sample) collected in the blood collection tube and the order number.

As shown in the drawing, this automatic blood collection tube preparation device includes four blood collection tube storage portions 20.
