[0012] [Embodiment] In order to facilitate understanding of the work support device 40 (work support system 36) according to this embodiment, the blood bag set 10 and the centrifuge device 30 will be described below in advance.

[0013] Fig. 1A is a configuration diagram of a blood bag set 10 (a first blood bag set 101). Fig. 1B is a configuration diagram of a blood bag set 10 (a second blood bag set 102) different from the first blood bag set 101.

[0014] The blood bag set 10 includes a blood collection needle 12, an initial blood flow removal bag 14, a plurality of branch connectors 16 (161, 162), a plurality of blood bags 18, a preservative solution bag 20, a plurality of tubes 22, and a filter 24.

[0015] The blood collection needle 12 is used to collect blood from a donor. The initial blood flow removal bag 14 stores the initial blood flow. The blood collection needle 12 and the initial blood flow removal bag 14 are connected via a branch connector 161.

[0016] Each of the blood bags 18 is a bag for storing blood components obtained by centrifuging blood. There are multiple types of blood components, such as red blood cells, plasma, and platelets.

[0017] 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.

[0018] The preservation solution bag 20 contains a preservation solution for preserving the centrifuged blood components. The preservation solution is, for example, a MAP solution (an additive solution for preserving red blood cells).

[0019] The multiple tubes 22 are connected to the blood collection needle 12, the initial blood removal bag 14, the multiple blood bags 18, or the preservation solution bag 20. The multiple tubes 22 form a flow path through which blood, blood components, or preservation solution flows. In order to appropriately open and close the flow path formed by the multiple tubes 22, the blood bag set 10 may further include one or more clamp members 26. The multiple tubes 22 include a first tube 221, a second tube 222, a third tube 223, and a fourth tube 224.

[0020] The first tube 221 is a tube 22 for allowing blood to flow into the whole blood bag 181. The first tube 221 is connected to the whole blood bag 181. The whole blood bag 181 is connected to the branch connector 161 via the first tube 221.

[0021] The second tube 222 connects the whole blood bag 181 to a branch connector 162 that is separate from the branch connector 161 .

[0022] The third tube 223 connects one of the blood bags 18 other than the whole blood bag 181 to the branch connector 162 .

[0023] The fourth tube 224 connects the preservation solution bag 20 and the branch connector 162. However, the fourth tube 224 of the second blood bag set 102 is connected to the branch connector 162 via a filter 24 and further another tube 22.

[0024] The filter 24 removes predetermined blood components, such as white blood cells, from the blood by filtering the blood. If necessary, the filter 24 may be changed to a filter that removes components other than white blood cells (such as platelets) from the blood.

[0025] The first blood bag set 101 further includes a blood collection bag 28. The blood collection bag 28 is connected to the branch connector 161 via a tube 22 arranged between the blood collection bag 28 and the branch connector 161. The blood collection bag 28 is also connected to the filter 24 via a tube 22 arranged between the blood collection bag 28 and the filter 24. The filter 24 is connected to the whole blood bag 181 via a first tube 221. Thus, the blood collection bag 28 is connected to the whole blood bag 181 via the filter 24. The whole blood bag 181 stores blood that has been filtered by the filter 24 to remove white blood cells.

[0026] The second blood bag set 102 does not have a blood collection bag 28. Furthermore, the filter 24 of the second blood bag set 102 is connected to the branch connector 162 via the tube 22 arranged between the filter 24 and the branch connector 162. According to the second blood bag set 102, blood containing white blood cells is stored in the whole blood bag 181. The white blood cells in the blood in the whole blood bag 181 can be removed by the filter 24 during or before or after the centrifugation process.

[0027] In a facility for collecting blood from donors (blood donation room), either the first blood bag set 101 or the second blood bag set 102 may be used.

[0028] FIG. 2 is a perspective view of the centrifugal separator 30. As shown in FIG.

[0029] The centrifuge device 30 is a device that performs a centrifugation process on the multiple blood bag sets 10 to separate the blood stored in each blood bag set 10 into multiple blood components. Each of the separated blood components is used as a blood product.

[0030] The centrifugal separator 30 includes a plurality of mounting sections 32. Each of the mounting sections 32 is a portion on which the blood bag set 10 is set. The centrifugal separator 30 performs a centrifugation process on the blood bag sets 10 set on each mounting section 32.

[0031] However, in order to set the blood bag set 10 on the mounting portion 32, it is necessary to accommodate the blood bag set 10 in a predetermined accommodation member 34 in advance.

[0032] The containing member 34 is a member that is detachable from the mounting portion 32. The containing member 34 holds the blood bag set 10 while the centrifugal separator 30 performs the centrifugation process. The shape of the containing member 34 is not limited to the example shown in FIG.

[0033] The blood bag set 10 is accommodated in the accommodating member 34 by an operator at the blood center. Here, a problem arises in that the accommodation procedure 70 for accommodating the blood bag set 10 in the accommodating member 34 differs depending on the type of blood bag set 10.

[0034] 1A and 1B, there are two types of blood bag sets 10, each having a different arrangement of the filter 24. The filter 24 of the first blood bag set 101 does not need to be housed in the housing member 34, but the filter 24 of the second blood bag set 102 needs to be housed in the housing member 34.

[0035] Furthermore, the number of blood bags 18 included in one blood bag set 10 varies depending on the number of types of blood components (blood products) required. The types of blood bag sets 10 are further subdivided depending on the number of blood bags 18.

[0036] In the storage operation, it is necessary to store multiple blood bags 18, filters 24, etc. in the storage member 34 in a predetermined arrangement according to the type of blood bag set 10. However, it may be difficult for an operator to understand the appropriate arrangement for each type of blood bag set 10.

[0037] The accommodation operation also includes a sealing operation for sealing at least one of the multiple tubes 22. The sealing operation may include an operation in which the worker cuts the sealed tube 22. The worker may use a tool such as a tube sealer (48) when performing the sealing operation. By performing the sealing operation in the correct procedure, blood (blood components) is prevented from leaking from the blood bag set 10 during the centrifugation process. However, for a worker who is not familiar with the sealing operation, it may be difficult to know which part of the multiple tubes 22 to seal, cut, etc.

[0038] In light of the above, the work support system 36 according to this embodiment will be described below. In the following description, the tube 22 to be sealed in the sealing work among the multiple tubes 22 will also be referred to as the tube 22 to be sealed.

[0039] FIG. 3 is a configuration diagram of a work support system 36 according to the embodiment.

[0040] The work support system 36 is a system for supporting a worker who performs collection work. The work support system 36 is provided in, for example, a blood center. The work support system 36 includes a plurality of work stations 38 and a work support device 40.

[0041] Each of the multiple work stations 38 is a work space for an operator to perform the operation of placing the blood bag set 10 in the containing member 34. The number of work stations 38 provided in the work support system 36 is not limited. The number of work stations 38 provided in the work support system 36 may be one.

[0042] Each of the multiple work stations 38 includes a work table 42, an imaging device 44, a display device 46, a tube sealer 48, a weighing device 50, and a reading device 52. The interior of the work station 38 is not limited to the example shown in FIG.

[0043] The work station 38 has a predetermined set space 54. The predetermined set space 54 is a space for setting the storage member 34. The worker sets the storage member 34 in the predetermined set space 54 and then starts the storage operation.

[0044] The predetermined set space 54 has, for example, a recess 42a formed in the workbench 42. The recess 42a accommodates the storage member 34, thereby limiting the movement range of the storage member 34. The predetermined set space 54 may have a holding device or the like for holding the storage member 34 instead of or in addition to the recess 42a. The work station 38 may further include a sensor 55 for detecting that the storage member 34 has been accommodated in the recess 42a. The sensor 55 is, for example, a weight sensor installed in the recess 42a (see FIG. 3). In this case, the sensor 55 outputs a detection signal corresponding to the weight of the object accommodated in the recess 42a. Therefore, when the storage member 34 is accommodated in the recess 42a, the sensor 55 outputs a detection signal corresponding to the weight of the storage member 34. Based on the detection signal, it is possible to detect that the storage member 34 has been accommodated in the recess 42a. The detection signal of the sensor 55 is input to the work support device 40.

[0045] The imaging device 44 is, for example, a camera. The imaging device 44 captures an image of a predetermined set space 54 and the tube sealer 48. The imaging device 44 also outputs captured image data 56 to the work support device 40.

[0046] The imaging device 44 may rotate or move so that an imaging range including a predetermined set space 54 and an imaging range including the tube sealer 48 can be changed. The rotation or movement of the imaging device 44 is achieved by an actuator such as a motor. In this case, the actuator may be controlled by the work support device 40 (an image acquisition unit 74 described later). Illustration of the actuator is omitted.

[0047] Also, a plurality of imaging devices 44 may be provided in the work station 38. Therefore, an imaging device 44 including a predetermined set space 54 in its imaging range and another imaging device 44 including a tube sealer 48 in its imaging range may be separately disposed in the work station 38.

[0048] The display device 46 includes a display screen 461. The display device 46 is controlled by the work support device 40 to appropriately display information on the display screen 461. The display screen 461 is, for example, a liquid crystal screen. The display device 46 is disposed so that the display screen 461 can be seen by the worker.

[0049] The tube sealer 48 is a device that seals the tube 22. The tube sealer 48 generates, for example, high frequency waves, ultrasonic waves, etc. in response to an operation by an operator. The tube 22 is sealed by the high frequency waves, ultrasonic waves, etc.

[0050] The weighing device 50 is a device that weighs the blood bag set 10 in response to an operation by an operator. The weighing device 50 outputs weight data 58 indicating the weighed weight to the work support device 40.

[0051] The reading device 52 is a barcode reader. A barcode indicating bag information 60 is attached to the blood bag set 10 in advance. The barcode is not shown, and the bag information 60 will be described in more detail later. The reading device 52 reads the bag information 60 from the barcode of the blood bag set 10 in response to an operation by an operator. The reading device 52 also outputs the read bag information 60 to the work support device 40. Note that the reading device 52 is not limited to a barcode reader (see also Variation 1 described later).

[0052] FIG. 4 is a configuration diagram of the work support device 40.

[0053] The work support device 40 is a computer that guides the worker on the procedure of the collection work. The work support device 40 may be included in a server device that manages the blood center, or may be installed as a device separate from the server device. The work support device 40 includes a storage unit 62 and a calculation unit 64.

[0054] The storage unit 62 includes a storage circuit, which includes one or more memories such as a random access memory (RAM) or a read only memory (ROM).

[0055] The memory unit 62 stores a work assistance program 66, a setting procedure 68, and a plurality of storing procedures 70. The work assistance program 66 is a program for causing the work assistance device 40 to execute the work assistance method according to this embodiment. The setting procedure 68 is a procedure for setting the storing member 34 in a predetermined set space 54. Each of the plurality of storing procedures 70 is a procedure for correctly performing a storing operation according to the type of blood bag set 10. Each storing procedure 70 may include a sealing procedure for correctly performing the above-mentioned sealing operation.

[0056] The data stored in the storage unit 62 is not limited to the work assistance program 66 and the plurality of storage procedures 70. The storage unit 62 may store various types of data as necessary.

[0057] The arithmetic unit 64 includes a processing circuit. This processing circuit includes, for example, one or more processors. However, the processing circuit of the arithmetic unit 64 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 64 may also include a discrete device.

[0058] The calculation unit 64 includes a bag information acquisition unit 72 , an image acquisition unit 74 , a storage member determination unit 76 , a display control unit 78 , a sealing time recording unit 80 , a weight acquisition unit 82 , a weight recording unit 84 , and an end time recording unit 86 .

[0059] The bag information acquisition unit 72, the image acquisition unit 74, the storage member determination unit 76, the display control unit 78, the sealing time recording unit 80, the weight acquisition unit 82, the weight recording unit 84, and the end time recording unit 86 are realized by the processor of the calculation unit 64 executing the work assistance program 66. At least a part of the bag information acquisition unit 72, the image acquisition unit 74, the storage member determination unit 76, the display control unit 78, the sealing time recording unit 80, the weight acquisition unit 82, the weight recording unit 84, and the end time recording unit 86 may be realized by the integrated circuit, discrete device, or the like described above.

[0060] The display control unit 78 controls the display device 46 to appropriately display various data stored in the storage unit 62 on the display screen 461.

[0061] The bag information acquisition unit 72 acquires the bag information 60 of the blood bag set 10. The acquired bag information 60 is stored in the storage unit 62.

[0062] The bag information 60 includes the type of the blood bag set 10 and identification information. The identification information includes, for example, an identification number previously assigned to each of the multiple blood bag sets 10. Of the bag information 60, only the identification information may be indicated in the barcode. In this case, the bag information acquisition unit 72 queries a database in which, for example, multiple pieces of identification information are associated with multiple types of blood bag sets 10 to find the type corresponding to the identification information acquired from the barcode. This allows the bag information acquisition unit 72 to acquire the type of the blood bag set 10 even if the type of the blood bag set 10 is not indicated in the barcode. The above database is, for example, stored in advance in the storage unit 62.

[0063] The image acquisition unit 74 acquires the image data 56 output from the imaging device 44. The acquired image data 56 is stored in the storage unit 62.

[0064] The storage member determination unit 76 determines whether or not a storage member 34 is set in a specified set space 54 based on at least one of image data 56 that includes the specified set space 54 in its imaging range and the detection signal of the sensor 55 described above.

[0065] When the storage member determination unit 76 determines that the storage member 34 is not set in the predetermined set space 54, it calls the display control unit 78. The called display control unit 78 controls the display device 46 to display the setting procedure 68 on the display screen 461.

[0066] This allows the worker to set the storage member 34 in the predetermined setting space 54 while checking the setting procedure 68 displayed on the display screen 461.

[0067] When the containing member determination unit 76 determines that the containing member 34 is set in the predetermined set space 54, it further determines whether or not the blood bag set 10 is contained in the containing member 34 based on the image data 56. Here, the containing member determination unit 76 may determine whether or not the blood bag set 10 is contained in the containing member 34 based on a detection signal from the above-mentioned sensor (weight sensor) 55. That is, when the blood bag set 10 is contained in the containing member 34, the sensor 55 outputs a detection signal according to the total weight of the containing member 34 and the blood bag set 10. Therefore, the containing member determination unit 76 can determine whether or not the blood bag set 10 is contained in the containing member 34 based on the detection signal from the sensor (weight sensor) 55. The containing member determination unit 76 may determine whether or not the blood bag set 10 is contained in the containing member 34 based on both the image data 56 and the detection signal from the sensor (weight sensor) 55.

[0068] The image data 56 used to determine whether or not the blood bag set 10 is contained in the containing member 34 is imaging data that includes the predetermined set space 54 (containing member 34) in the imaging range. This imaging data may be the same image data 56 as the image data 56 used to determine whether or not the containing member 34 is set in the predetermined set space 54, or may be different image data 56.

[0069] When the containing member determination unit 76 determines that the blood bag set 10 is not contained in the containing member 34 set in the predetermined set space 54, it calls the display control unit 78. The display control unit 78 reads out the containing procedure 70 corresponding to the acquired type of blood bag set 10 from the storage unit 62. The display control unit 78 also causes the read out containing procedure 70 to be displayed on the display screen 461.

[0070] This allows the operator to perform the storage operation while checking the operation procedure according to the type of blood bag set 10. Therefore, the operator is less likely to make a mistake in the storage procedure 70.

[0071] As described above, the storing procedure 70 includes the sealing procedure. In this regard, the storing member determination unit 76 also determines whether or not all of the tubes to be sealed 22 in the blood bag set 10 that the worker is performing the storing operation are sealed based on the sealing procedure. This determination is made based on image data 56 in which the tubes to be sealed 22 are captured.

[0072] The tubes 22 to be sealed corresponding to the type of each blood bag set 10 are stored in advance in the storage unit 62. For example, the tubes 22 to be sealed corresponding to the type of each blood bag set 10 are stored in the aforementioned database. The image acquisition unit 74 acquires image data 56 of the tubes 22 to be sealed from the imaging device 44.

[0073] When the containing member determination unit 76 determines that all of the tubes to be sealed 22 are not sealed, it calls the display control unit 78. In this case, the display control unit 78 causes the display screen 461 to display at least one of the tubes to be sealed 22 that are not sealed and the sealing procedure of the tubes to be sealed 22.

[0074] This allows the worker to carry out the sealing work while checking at least one of the unsealed tubes 22 to be sealed and the sealing procedure, thereby reducing the risk that the worker will make a mistake in the sealing procedure.

[0075] The sealing time recording unit 80 stores the sealing completion time, at which the containing member determination unit 76 determines that all of the sealing target tubes 22 have been sealed, in the memory unit 62 in association with the blood bag set 10. For example, the sealing time recording unit 80 stores the sealing completion time in the aforementioned database in association with the identification information of the corresponding blood bag set 10. This improves the traceability of the blood center.

[0076] The weight acquisition unit 82 acquires weight data 58 of the blood bag set 10 contained in the containing member 34. The weight of the blood bag set 10 is measured using a weighing device 50 provided in the work station 38. The procedure of measuring the weight of the blood bag set 10 may be included in the containing procedure 70.

[0077] The weight of the blood bag set 10 indicated in the weight data 58 indicates the total weight of the contents (blood, preservative solution) of the blood bag set 10 and the blood bag set 10. However, the weight indicated in the weight data 58 may include the weight of the containing member 34. In other words, the weight acquiring unit 82 may acquire the weight data 58 obtained by having the weighing device 50 weigh the containing member 34 containing the blood bag set 10.

[0078] The weight recording unit 84 stores the weight indicated by the acquired weight data 58 in the memory unit 62 in association with the blood bag set 10. For example, the weight recording unit 84 stores the weight indicated by the acquired weight data 58 in association with the identification information of the corresponding blood bag set 10 in the database described above. This further improves the traceability of the blood center.

[0079] The end time recording unit 86 stores the work end time, at which the containing member determination unit 76 determines that the blood bag set 10 has been contained in the containing member 34, in the memory unit 62 in association with the blood bag set 10. For example, the end time recording unit 86 stores the work end time in the aforementioned database in association with the identification information of the corresponding blood bag set 10. This further improves the traceability of the blood center.

[0080] FIG. 5 is a flowchart illustrating the flow of a task support method according to the embodiment.

[0081] The work support device 40 executes a work support method as illustrated in Fig. 5. This work support method includes a bag information acquisition step S1, an image acquisition step S2, and a storage member determination step S3 (S31 to S33). The work support method in Fig. 5 further includes a setting procedure display step S4, a sealing time recording step S5, a storage procedure display step S6 (S61, S62), a weight acquisition step S7, a weight recording step S8, and an end time recording step S9.

[0082] In the bag information acquisition step S1, the bag information acquisition unit 72 acquires the type of the blood bag set 10.

[0083] In the image acquisition step S2, the image acquisition unit 74 acquires image data 56 of the storage member 34. Note that, in order to execute each of steps S31 to S33 in the storage member determination step S3 described below, the image acquisition unit 74 may acquire other image data 56 as appropriate even after acquiring the image data 56 once.

[0084] In the containing member determination step S3, the containing member determination unit 76 determines whether or not the blood bag set 10 is contained in the containing member 34 based on at least one of the image data 56 and the detection signal of the sensor 55. In the containing member determination step S3, first, it is determined whether or not the containing member 34 is set in a predetermined set space 54 based on at least one of the image data 56 and the detection signal of the sensor 55 (S31).

[0085] If the storage member 34 is not set in the predetermined setting space 54 (S31: NO), a setting procedure display step S4 is executed. In the setting procedure display step S4, the display control unit 78 causes the display screen 461 to display the setting procedure 68.

[0086] When the containing member 34 is set in the predetermined set space 54 (S31: YES), the containing member determination unit 76 determines whether or not the blood bag set 10 is contained in the containing member 34 (S32). Here, the containing member determination unit 76 determines whether or not the blood bag set 10 is contained in the containing member 34 based on at least one of the image data 56 and the detection signal of the sensor 55.

[0087] If the blood bag set 10 is not contained in the containing member 34 (S32: NO), the containing member determination unit 76 determines whether the tube to be sealed 22 is sealed or not based on the image data 56 (S33). Here, it is determined whether the tube to be sealed 22 of the blood bag set 10 is sealed or not.

[0088] If the tube 22 to be sealed is sealed (S33: YES), a sealing time recording step S5 is executed. In the sealing time recording step S5, the sealing time recording unit 80 causes the storage unit 62 to store the sealing completion time in association with the blood bag set 10.

[0089] 5, it is possible that the tube 22 to be sealed is determined to be sealed two or more times. The sealing time recording step S5 is executed only the first time that the tube 22 to be sealed is determined to be sealed after START.

[0090] If the tube 22 to be sealed is not sealed (S33: NO), or if the sealing time recording step S5 is completed, the storage procedure display step S6 is executed. In the storage procedure display step S6, the display control unit 78 causes the display screen 461 to display the storage procedure 70 corresponding to the type of blood bag set 10.

[0091] Here, if all of the tubes to be sealed 22 have already been sealed (S33: YES), there is no need to display the sealing procedure on the display screen 461. Therefore, the display of the sealing procedure may be omitted (S61).

[0092] On the other hand, if any unsealed tubes to be sealed 22 remain (S33: NO), the display control unit 78 causes the storage procedure 70 including the sealing procedure to be displayed on the display screen 461 (S62). However, the display control unit 78 may also cause the display screen 461 to display the unsealed tubes to be sealed 22 instead of the sealing procedure. Furthermore, the display control unit 78 may also cause the display screen 461 to display both the unsealed tubes to be sealed 22 and the sealing procedure.

[0093] When the blood bag 18 is contained in the containing member 34 (S32: YES), the weight acquisition step S7 is executed. In the weight acquisition step S7, the weight acquisition unit 82 acquires the weight of the blood bag set 10.

[0094] After the weight acquisition step S7, a weight recording step S8 is executed. In the weight recording step S8, the weight recording unit 84 stores the acquired weight of the blood bag set 10 in the memory unit 62 in association with the blood bag set 10.

[0095] After the weight recording step S8, a completion time recording step S9 is executed. In the completion time recording step S9, the completion time recording unit 86 stores the work completion time in the memory unit 62 in association with the blood bag set 10. This ends the work support method.

[0096] 5, there may be a case where the sealing time recording step S5 is not executed even once until it is determined that the blood bag 18 is contained in the containing member 34. In that case, the work support device 40 may execute the sealing time recording step S5 at the timing when it is determined that the blood bag set 10 is contained in the containing member 34, and then execute the weight acquisition step S7. This makes it possible to ensure the traceability of the blood center.

[0097] [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.

[0098] (Variation 1) The bag information 60 may be stored in an electronic tag. The electronic tag stores the bag information 60, for example, by RFID (Radio Frequency Identifier). The electronic tag is attached to the blood bag set 10. In this case, the reading device 52 is an RFID reader. In this case, a barcode indicating the bag information 60 does not need to be attached to the blood bag set 10.

[0099] (Variation 2) The work support device 40 may be formed of a plurality of computers that communicate with each other via a network. For example, the bag information acquisition unit 72, the image acquisition unit 74, the storage member determination unit 76, the display control unit 78, the sealing time recording unit 80, the weight acquisition unit 82, the weight recording unit 84, and the end time recording unit 86 may each be realized by a separate computer. In this case, the plurality of computers communicate with each other via the network.

[0100] At least a part of the storage unit 62 may be realized by an external storage device installed in a location separate from the work support device 40. In this case, the work support device 40 and the external storage device communicate with each other via a network.
