[0010] [Embodiment] FIG. 1 is a configuration diagram of a blood processing management system 10 according to an embodiment.

[0011] The blood processing and management system 10 includes an allocation device 12 and a plurality of centrifuge devices 14. The blood processing and management system 10 is installed in, for example, a blood center.

[0012] Each of the multiple centrifuge devices 14 is a device that separates blood contained in multiple blood bag sets 16 (161, 162) into multiple blood components by centrifugation (see also Figures 2A, 2B, and 4). The blood is provided in advance by a donor. Each of the multiple blood components obtained by centrifuging the blood is used as a blood product.

[0013] Fig. 2A is a configuration diagram of a blood bag set (first blood bag set) 161. Fig. 2B is a configuration diagram of a blood bag set (second blood bag set) 162 different from the first blood bag set 161.

[0014] The blood bag set 16 includes a plurality of blood bags 18, a storage solution bag 20, a first tube 22, and a second tube 24.

[0015] Each of the plurality of blood bags 18 is a bag for storing a blood component obtained by centrifuging blood. There are multiple types of blood components, such as red blood cells, plasma, platelets, etc. The plurality of blood bags 18 stores different types of blood components.

[0016] The multiple blood bags 18 include at least one whole blood bag 181. The whole blood bag 181 stores blood before it is centrifuged. The whole blood bag 181 also stores blood components remaining in the whole blood bag 181 after the centrifugation process.

[0017] The preservation solution bag 20 contains a preservation solution for facilitating preservation of the centrifuged blood components. The preservation solution is, for example, MAP solution (additive solution for preserving red blood cells).

[0018] The first tube 22 is a tube for allowing blood to flow into the whole blood bag 181. However, the first tube 22 is sealed after blood is introduced into the whole blood bag 181. This prevents blood from leaking from the whole blood bag 181.

[0019] The second tube 24 connects the multiple blood bags 18 and the storage solution bag 20. The blood bag set 16 may further include one or more clamp members to appropriately open and close the second tube 24. The clamp members are not shown in the drawings.

[0020] The second blood bag set 162 further includes a filter 26 .

[0021] The filter 26 is disposed between the blood bag 18 and the preservation solution bag 20 via the second tube 24. The filter 26 removes white blood cells from the blood by filtering the blood. Note that the filter 26 may remove components other than white blood cells from the blood as necessary.

[0022] The first blood bag set 161 and the second blood bag set 162 are used depending on whether or not white blood cells are removed from the blood before it is placed in the whole blood bag 181.

[0023] That is, if white blood cells are not previously removed from the blood, it is necessary to filter the blood using filter 26. Therefore, if white blood cells are not previously removed from the blood, second blood bag set 162 having filter 26 is used.

[0024] On the other hand, when white blood cells are removed from the blood in advance, there is no need to use the filter 26. Therefore, when white blood cells are removed from the blood in advance, the first blood bag set 161 can be used.

[0025] The configuration of the blood bag set 16 is not limited to the examples shown in Figures 2A and 2B. For example, the number of blood bags 18 included in the blood bag set 16 may be changed depending on the number of types of blood products required.

[0026] FIG. 3 is a configuration diagram of the allocation device 12 according to the embodiment.

[0027] The allocation device 12 is a computer that allocates a plurality of blood bag sets 16 to each of a plurality of centrifuge devices 14. The allocation device 12 may be included in a server device that manages a blood center. The allocation device 12 includes a memory unit 28 and a calculation unit 30.

[0028] The storage unit 28 includes a storage circuit, which includes one or more memories such as a random access memory (RAM) or a read only memory (ROM).

[0029] The storage unit 28 stores a blood processing management program 32. The blood processing management program 32 is a program for causing the allocation device to execute the allocation method according to this embodiment.

[0030] The data stored in the memory unit 28 is not limited to the blood processing management program 32. The memory unit 28 may store various data as necessary.

[0031] The arithmetic unit 30 includes a processing circuit. The processing circuit includes, for example, one or more processors. However, the processing circuit of the arithmetic unit 30 may include an integrated circuit such as an ASIC (Application Specific Integrated Circuit) or an FPGA (Field-Programmable Gate Array). The processing circuit of the arithmetic unit 30 may also include a discrete device.

[0032] The calculation unit 30 includes an acquisition unit 34 , a group creation unit 36 ​​, an allocation unit 38 , and a condition determination unit 40 .

[0033] The acquiring unit 34, the group creating unit 36, the allocating unit 38, and the condition determining unit 40 are realized by the processor of the computing unit 30 executing the blood processing management program 32. However, the acquiring unit 34, the group creating unit 36, the condition determining unit 40, and the allocating unit 38 may be at least partially realized by the above-mentioned integrated circuits, discrete devices, etc.

[0034] The acquisition unit 34 acquires bag information 42 for each of the multiple blood bag sets 16. The bag information 42 includes identification information and multiple condition determination elements. The identification information includes, for example, an identification number previously assigned to each of the multiple blood bag sets 16. Each of the multiple condition determination elements is an element for determining the centrifugation conditions of the centrifugation process performed on the blood bag set 16 corresponding to the bag information 42. The multiple condition determination elements include, for example, (1) target preparation, (2) blood collection date and time, (3) hematocrit value, (4) blood triglyceride concentration, (5) whether removal process is required, and (6) weight.

[0035] (1) The target product indicates the type of blood product corresponding to the blood bag set 16. (2) The blood collection date and time indicates the blood collection date of the blood stored in the blood bag set 16 and the time when the blood was collected. For example, a plurality of categories are determined in advance according to the elapsed time from the time when the blood contained in the blood bag set 16 was collected. Each blood bag set 16 belongs to one of the plurality of categories according to the elapsed time from the time when the blood contained in the blood bag set 16 was collected. The magnitude of the centrifugal force applied by the centrifuge device 14 to the blood bag set 16 differs according to the category to which the blood bag set 16 belongs. That is, the magnitude of the centrifugal force applied by the centrifuge device 14 to the blood bag set 16 differs according to the day and time when the blood was collected. The blood collection date and time may indicate the blood collection date and the time zone when the blood was collected. In this case, each blood bag set 16 belongs to one of the plurality of categories according to the elapsed time from the time zone when the blood contained in the blood was collected. (3) Hematocrit value indicates the percentage of red blood cells in the blood stored in the blood bag set 16. (4) Blood triglyceride concentration indicates the percentage of lipids in the blood stored in the blood bag set 16. Blood with a hematocrit value or blood lipid level exceeding a specified value is distinguished from other blood as special blood. (5) Need for removal process indicates whether or not a process to remove white blood cells from the blood stored in the blood bag set 16 is necessary during or after the centrifugation process. (6) Weight indicates the weight of the blood bag set 16. The weight of the blood bag set 16 includes the weight of the contents of the blood bag set 16 (blood, preservative solution, etc.).

[0036] Among the above (1) to (6), (1) the target preparation and (5) whether or not removal processing is required can be determined in advance depending on the configuration of the blood bag set 16. In addition, (2) blood collection date and time, (3) hematocrit value, (4) blood neutral fat concentration, and (6) weight can be determined in advance for each blood bag set 16 as blood collection conditions. Therefore, all of the above (1) to (6) can be associated with identification information before each blood bag set 16 is brought into the blood center.

[0037] The bag information 42 including the above-mentioned identification information and a plurality of condition determining elements is indicated, for example, by a barcode of each blood bag set 16. The bag information 42 may be stored in an electronic tag attached to each blood bag set 16. The electronic tag stores the bag information 42 by, for example, RFID (Radio Frequency Identification). The acquiring unit 34 acquires the bag information 42 of the plurality of blood bag sets 16 brought into the blood center via a reading device such as a barcode reader or an RFID reader.

[0038] Of the identification information and the multiple condition determination elements, only the identification information may be acquired from the barcode, electronic tag, or the like. In this case, the acquisition unit 34 queries a database in which, for example, multiple identification information and multiple condition determination elements are associated with each other, for the multiple condition determination elements corresponding to the acquired identification information. This allows the acquisition unit 34 to acquire the multiple condition determination elements even if the multiple condition determination elements are not acquired from a barcode, electronic tag, or the like. The database is, for example, stored in advance in the storage unit 28.

[0039] The acquired bag information 42 is stored in the memory unit 28. The bag information 42 stored in the memory unit 28 may be added or updated as necessary. For example, a more accurate weight of each blood bag set 16 may be measured after it is delivered to the blood center and stored in the memory unit 28.

[0040] The group creation unit 36 ​​groups the multiple blood bag sets 16 based on at least one of the above (1) to (6). The group creation unit 36 ​​preferably creates groups taking into consideration all of the above (1) to (6), but may create groups taking into consideration one to five of the above (1) to (6).

[0041] For example, the group creation unit 36 ​​may group the multiple blood bag sets 16 into groups of blood bag sets 16 that have the same target product and the same blood collection date and time.

[0042] The group creating unit 36 ​​may also separate the plurality of blood bag sets 16 into blood bag sets 16 whose hematocrit values ​​are equal to or greater than a predetermined value and blood bag sets 16 whose hematocrit values ​​are less than the predetermined value. Similarly, the group creating unit 36 ​​may separate the plurality of blood bag sets 16 into blood bag sets 16 whose blood neutral fat concentrations are equal to or greater than a predetermined value and blood bag sets 16 whose blood neutral fat concentrations are less than the predetermined value.

[0043] Furthermore, the group creating unit 36 ​​may separate the multiple blood bag sets 16 into blood bag sets 16 that require the white blood cell removal process and blood bag sets 16 that do not require the white blood cell removal process.

[0044] The group creating unit 36 ​​may divide the blood bag sets 16 based on the weight of each blood bag set 16. However, it is not essential that all the blood bag sets 16 belonging to the same group have exactly the same weight. It is preferable that the group creating unit 36 ​​includes at least one pair of blood bag sets 16 whose weight difference falls within a predetermined range in the same group.

[0045] According to the above-described group creation unit 36, a plurality of blood bag sets 16 are divided into a plurality of groups that can be subjected to a centrifugation process under the same centrifugation conditions. The plurality of groups created by the group creation unit 36 ​​are stored in the memory unit 28.

[0046] The allocation unit 38 allocates the plurality of blood bag sets 16 to the plurality of centrifuge devices 14 based on the grouping result.

[0047] The allocation unit 38 performs allocation so that two or more blood bag sets 16 belonging to different groups are not centrifuged together in a single run of the centrifuge device 14. For example, the allocation unit 38 allocates a different centrifuge device 14 for each group.

[0048] As described above, there is a case where a pair of blood bag sets 16 whose weight difference falls within a predetermined range is included in at least one of the groups. In this case, it is preferable that the allocation unit 38 also determines the arrangement of the pair of blood bag sets 16 in the centrifuge device 14, as described below.

[0049] FIG. 4 is a perspective view of the centrifuge device 14.

[0050] The centrifugal separator 14 has a plurality of mounting parts 44. The mounting parts 44 are arranged at approximately equal intervals in the circumferential direction around a central axis (centrifugal central axis) A. For illustrative purposes, the centrifugal separator 14 has six mounting parts 44.

[0051] Each of the plurality of mounting parts 44 is a portion on which the blood bag set 16 is set. Each of the plurality of mounting parts 44 has, for example, a concave shape capable of accommodating a predetermined containing member. The blood bag set 16 is set on the mounting part 44 in a state in which it is accommodated in the predetermined containing member. The predetermined containing member is not shown in the drawing.

[0052] During centrifugation, the multiple mounting parts 44 rotate around the central axis A. As a result, centrifugal force acts on the multiple blood bag sets 16 set on the multiple mounting parts 44, separating the blood into multiple blood components.

[0053] If the weight difference between the two blood bag sets 16 arranged point-symmetrically with respect to the central axis A is relatively large, the weight balance of the centrifugal separator 14 will deteriorate, resulting in adverse effects on the centrifugal separation process.

[0054] In consideration of this, when there is a pair of blood bag sets 16 whose weight difference falls within a predetermined range, the allocation unit 38 allocates the placement in the centrifuge device 14 so that the pair is set point-symmetrically with respect to the central axis line A. This prevents the weight balance of the centrifuge device 14 from becoming worse, thereby preventing adverse effects on the centrifugation process.

[0055] The condition determination unit 40 determines the centrifugation conditions for each group based on a plurality of condition determination elements. Here, the condition determination unit 40 selects one blood bag set 16 for each of the plurality of groups. The condition determination unit 40 determines the centrifugation conditions based on a plurality of condition determination elements of the selected blood bag set 16. In this way, by determining the centrifugation conditions for one blood bag set 16 in each group, the centrifugation conditions for all the remaining blood bag sets in the group are automatically determined. Therefore, according to this embodiment, the processing load of the condition determination unit 40 is prevented from increasing as the number of blood bag sets 16 increases.

[0056] The centrifugation conditions for each blood bag set 16 determined by the condition determining unit 40 are stored in the memory unit 28 in association with the identification information of each blood bag set 16.

[0057] The condition determination unit 40 may transmit the centrifugation conditions of the corresponding blood bag set 16 to each of the multiple centrifuge devices 14. This allows the centrifugation conditions to be automatically set in each of the multiple centrifuge devices 14. In this case, the condition determination unit 40 transmits the centrifugation conditions to each of the multiple centrifuge devices 14 via the network.

[0058] According to the allocation device 12 described above, a plurality of blood bag sets 16 can be appropriately allocated to each of a plurality of centrifuge devices 14 without depending on the skill of an operator.

[0059] FIG. 5 is a flowchart illustrating the flow of a blood processing management method according to an embodiment.

[0060] The allocating device 12 can execute, for example, the blood processing management method of Fig. 5. This blood processing management method includes an acquisition step S1, a group creation step S2, an allocation step S3, and a condition determination step S4.

[0061] In the acquisition step S1, the acquisition unit 34 acquires a plurality of condition determination elements for each blood bag set 16. The acquisition step S1 is performed sequentially, for example, when the blood bag set 16 is carried into the blood center.

[0062] In the group creation step S2, the group creation unit 36 ​​groups the multiple blood bag sets 16 based on multiple condition determination elements of each blood bag set 16. The group creation unit 36 ​​creates multiple groups for each blood bag set 16 that can be centrifuged under the same centrifugation conditions.

[0063] In the allocation step S3, the allocation unit 38 allocates the plurality of blood bag sets 16 to the plurality of centrifuge devices 14 based on the grouping result.

[0064] In the condition determination step S4, the condition determination unit 40 determines the centrifugation conditions for each blood bag set 16. When the condition determination step S4 is performed after the group creation step S2, by determining the centrifugation conditions for one blood bag set 16 in each group, the centrifugation conditions for all the remaining blood bag sets 16 in the group can be automatically determined.

[0065] According to the above-described blood processing management method, a plurality of blood bag sets 16 can be appropriately assigned to each of a plurality of centrifuge devices 14 without depending on the skill of an operator.

[0066] [Variations] Modifications of the above embodiment are described below. However, descriptions that overlap with the above embodiment are omitted as much as possible in the following description. Elements that have already been described in the above embodiment are given the same reference numerals as in the above embodiment unless otherwise specified.

[0067] (Variation 1) FIG. 6 is a configuration diagram of an allocation device 121(12) according to the first modification.

[0068] The allocating device 121 includes the components (see the embodiment) of the allocating device 12. The allocating device 121 further includes a recording unit 46 and an output control unit 48.

[0069] The recording unit 46 stores a plurality of management records 50 relating to a plurality of blood bag sets 16 (bag information 42) in the memory unit 28. The recording unit 46 has a formulation record section 461, a weight record section 462, a time record section 463, a group record section 464, a condition record section 465, a centrifugation record section 466, and an operator record section 467. The plurality of management records 50 include a formulation record, a weight record, a delivery time, a group record, a condition record, a centrifugation record, and an operator record, which will be described below.

[0070] The product record unit 461 stores a plurality of product records associated with each of the plurality of bag information 42 in the memory unit 28. The product record indicates the type of blood product corresponding to each blood bag set 16. The product record may indicate the blood product corresponding to each blood bag 18 included in the corresponding blood bag set 16.

[0071] As described above, the storage unit 28 may store a database in which a plurality of pieces of identification information are associated with a plurality of condition determining elements (types of blood products). The preparation recording unit 461 may be used, for example, to construct or modify the database.

[0072] The weight recording unit 462 stores a plurality of weight records associated with each of the plurality of bag information 42 in the memory unit 28. The weight records indicate the weight of each blood bag set 16. The weight records may include the weight of each blood bag 18 included in the corresponding blood bag set 16. The weight of each blood bag set 16 is measured by an operator using a weighing scale.

[0073] The weight recording unit 462 may also store multiple weight records associated with the same bag information 42 in the storage unit 28. For example, the weight recording unit 462 stores in the storage unit 28 a weight record indicating the weight of a certain blood bag set 16 immediately after it is carried into the blood center. After that, the blood bag set 16 is subjected to a white blood cell removal process. The weight recording unit 462 may further store in the storage unit 28 a weight record indicating the weight of the blood bag set 16 after the white blood cell removal process.

[0074] As described above, the storage unit 28 may store a database in which a plurality of pieces of identification information are associated with a plurality of condition determining elements (weights). The weight recording unit 462 may be used, for example, to construct or modify the database.

[0075] The time recording unit 463 stores in the memory unit 28 a plurality of delivery times associated with each of the plurality of bag information 42. The delivery times indicate the times when the corresponding blood bag sets 16 were delivered to the blood center. For example, the time recording unit 463 stores in the memory unit 28 the times when the acquisition unit 34 acquired the bag information 42 as the delivery times of the blood bag sets 16 corresponding to the bag information 42.

[0076] The group recording unit 464 stores a plurality of group records associated with each of the plurality of bag information 42 in the memory unit 28. As described above, the plurality of blood bag sets 16 are divided into a plurality of groups by the group creating unit 36. The group record indicates the group to which the corresponding blood bag set 16 belongs.

[0077] The condition recording unit 465 stores a plurality of condition records associated with each of the plurality of bag information 42 in the memory unit 28. The condition records indicate the centrifugation conditions of the corresponding blood bag sets 16. As described above, the group creation unit 36 ​​determines the centrifugation conditions of each blood bag set 16 for each group.

[0078] The centrifugation record unit 466 stores a plurality of centrifugation records associated with each of the plurality of bag information 42 in the memory unit 28. The centrifugation record indicates the processing result of the centrifugation process performed on the corresponding blood bag set 16. The processing result includes, for example, the end time of the centrifugation process.

[0079] The worker record unit 467 stores in the memory unit 28 a plurality of worker records associated with each of a plurality of bag information 42. The worker record is a record related to a worker who performed work, processing, etc. on the blood bag set 16. The worker record includes, for example, identification information of the worker, the work or processing performed by the worker, and the time when the work or processing was performed.

[0080] The identification information of the worker is acquired, for example, via a reading device installed in the blood center. For example, before each worker processes the blood bag set 16, the reading device reads the barcode (see also the embodiment) of the blood bag set 16. After each worker reads the barcode (see also the embodiment) of the blood bag set 16, the reading device reads his / her own identification information. As a result, the blood bag set 16 to be processed and the identification information of the worker associated with the previously read bag information 42 are input to the allocation device 12 via the reading device. The identification information of each worker is indicated, for example, by a barcode or an electronic tag attached to an ID card held by each worker. The work and processing performed can be identified based on which reading device was used, for example, by preparing a different reading device for each type of work.

[0081] The above-described recording unit 46 improves the traceability of the operations carried out in the blood center.

[0082] The output control unit 48 outputs a plurality of management records 50 to the outside. For example, in response to a request from an operator issued via a specified terminal, the output control unit 48 outputs the management records 50 instructed by the operator to the outside. The method of external output is, for example, data transmission via a specified network to a computer, display device, etc. installed outside the blood processing management system 10. The output control unit 48 makes it possible to easily output the management records 50 to an external computer.

[0083] FIG. 7 is a flowchart illustrating the flow of a blood processing management method according to the first modification.

[0084] The allocation device 121 can execute the blood processing management method of Fig. 7. The blood processing management method of Fig. 7 includes the components of the blood processing management method of Fig. 5. The blood processing management method of Fig. 7 further includes a plurality of recording steps (S5 to S11) and an output control step S12. The plurality of recording steps include a formulation recording step S5, a delivery time recording step S6, a weight recording step S7, a worker recording step S8, a group recording step S9, a condition recording step S10, and a centrifugation recording step S11.

[0085] In the formulation recording step S5, the formulation recording unit 461 stores a plurality of formulation records associated with each of the plurality of bag information 42 in the storage unit 28. The formulation recording step S5 is performed based on, for example, a result of execution of the obtaining step S1.

[0086] However, if a database showing the correspondence between a plurality of pieces of identification information and a plurality of types of blood products is constructed in advance, the formulation record step S5 may be skipped.

[0087] In the carrying-in time recording step S6, the time recording unit 463 stores the carrying-in times associated with each of the plurality of pieces of bag information 42 in the storage unit 28. The carrying-in time recording step S6 is performed, for example, after the acquisition step S1.

[0088] In the weight recording step S7, the weight recording unit 462 stores a plurality of weight records associated with each of the plurality of bag information 42 in the memory unit 28. The weight recording step S7 is performed, for example, after the plurality of blood bag sets 16 are carried into the blood center. Therefore, the weight recording step S7 is performed, for example, after the carrying-in time recording step S6.

[0089] In the worker recording step S8, the worker recording unit 467 stores a plurality of worker records associated with each of the plurality of bag information 42 in the memory unit 28. The worker recording step S8 is performed, for example, after the weight of the blood bag set 16 is measured, in order to record the worker who performed the weight measurement work. Therefore, the worker recording step S8 is performed, for example, after the weight recording step S7.

[0090] In the group recording step S9, the group recording section 464 stores in the storage section 28 a plurality of group records associated with each of the plurality of bag information 42. The group recording step S9 is performed based on the execution result of the group creation step S2.

[0091] In the condition recording step S10, the condition recording unit 465 stores a plurality of condition records associated with the plurality of pieces of bag information 42 in the storage unit 28. The condition recording step S10 is performed based on the execution result of the condition determination step S4.

[0092] In the centrifugation recording step S11, the centrifugation recording unit 466 stores a plurality of centrifugation records associated with each of the plurality of bag information 42 in the memory unit .

[0093] In the flow chart of FIG. 7, the centrifugation process is performed between the condition determination step S4 and the centrifugation record step S11.

[0094] Also, after the centrifugation process, the weight recording step S7 may be performed again. In the weight recording step S7 performed after the centrifugation process, the weight of each blood bag 18 in the centrifuged blood bag set 16 may be recorded. Furthermore, the operator recording step S8 may be performed again to record the operator who performed the weight measurement after the centrifugation process.

[0095] In the output control step S12, the output control unit 48 outputs the management record 50 to the outside. Note that the output control step S12 is performed in response to an instruction from an operator. Therefore, the execution timing of the output control step S12 is not limited to the example shown in FIG.

[0096] (Variation 2) The contents of the multiple condition determining elements are not limited to the above (1) to (6). For example, the multiple condition determining elements may further include the blood type of the donor.

[0097] (Variation 3) The contents of the bag information 42 are not limited to the identification information and the multiple condition determining elements. For example, the bag information 42 may include the manufacturer or model number of the blood bag set 16.

[0098] (Variation 4) The allocation device 12 may be formed of a plurality of computers that communicate with each other via a network. For example, the acquisition unit 34, the group creation unit 36, the allocation unit 38, the condition determination unit 40, and the recording unit 46 may each be realized by a separate computer. In this case, the plurality of computers communicate with each other via the network.

[0099] Furthermore, at least a part of the storage unit 28 may be realized by an external storage device installed in a location separate from the allocating device 12. In this case, the allocating device 12 and the external storage device communicate with each other via a network.

[0100] (Variation 5) The condition determining unit 40 may determine the centrifugation conditions for each of the plurality of blood bag sets 16 based on the plurality of condition determining elements for each of the plurality of blood bag sets 16. In this case, the condition determining unit 40 may determine the centrifugation conditions for each of the plurality of blood bag sets 16 before the plurality of groups are created.

[0101] (Combination of multiple modifications) The above-described multiple modified examples may be combined as appropriate within a range that does not contradict each other.

[0102] [Inventions Obtained from the Embodiments] The invention that can be understood from the above-described embodiment and modifications will be described below.

[0115] This allows a plurality of blood bag sets to be appropriately assigned to each of a plurality of centrifuge devices without relying on the skill of an operator.

[0116] The plurality of condition determining elements may include types of blood products corresponding to the blood bag sets, and in the group creating step, the plurality of blood bag sets may be divided into blood bag sets each having the same type of blood product corresponding thereto. Thus, the plurality of blood bag sets belonging to the same group correspond to the same type of blood product.

[0117] The plurality of condition determining elements may further include a blood collection date and time, each of the plurality of blood bag sets may belong to one of a plurality of categories that are predetermined based on the blood collection date and time, and in the group creating step, the plurality of blood bag sets may be divided into the blood bag sets having the same category, whereby the plurality of blood bag sets belonging to the same group correspond to the same blood collection date and time.

[0118] The plurality of condition determining elements may further include at least one of a hematocrit value and a blood triglyceride concentration, and in the group creating step, the plurality of blood bag sets may be divided into blood bag sets whose hematocrit value or blood triglyceride concentration is equal to or greater than a predetermined value and blood bag sets whose hematocrit value or blood triglyceride concentration is less than the predetermined value, whereby blood bag sets storing special blood and blood bag sets storing non-special blood are divided into different groups.

[0119] The plurality of condition determining elements may further include whether or not a process for removing white blood cells contained in the blood is necessary, and in the group creating step, the plurality of blood bag sets may be divided into the blood bag sets that require the process for removing white blood cells and the blood bag sets that do not require the process for removing white blood cells during or after centrifugation, thereby dividing the blood bag sets that require the process for removing white blood cells during or after centrifugation into different groups from the blood bag sets that do not require the process for removing white blood cells.

[0120] The plurality of condition determining elements may further include weights of the blood bag sets, and in the group creating step, pairs of the blood bag sets whose weight difference falls within a predetermined range may be included in the same group, and in the allocating step, the plurality of blood bag sets may be allocated to the plurality of centrifuge devices such that the pairs are set point-symmetrically with respect to a centrifugal central axis of the centrifuge device, thereby preventing the weight balance of the centrifuge device from becoming worse.

[0121] The second invention may further include a condition determination step (S4) of determining the centrifugation conditions of the group created in the group creation step based on the condition determination elements of the blood bag sets belonging to the group. This allows the centrifugation conditions to be automatically determined, reducing the burden on workers.

[0122] The second invention may further include a recording step of storing a plurality of management records (50) relating to a plurality of the blood bag sets in the memory unit (28), thereby improving traceability of the treatment process in the blood center.

[0123] The recording step may include at least one of the following steps: a step (S5) of storing the type of blood product corresponding to the blood bag set in the memory unit, a step (S7) of storing the weight of the blood bag set in the memory unit, a step (S6) of storing the time when the blood bag set was carried into the blood center in the memory unit, a step (S9) of storing the group to which the blood bag set belongs in the memory unit, a step (S10) of storing the centrifugation conditions of the blood bag set in the memory unit, and a step (S8) of storing records related to the workers involved in the blood bag set in the memory unit.
