[0005] An object of the present disclosure is to solve the problem described above. [Means for Solving the Problem]

[0006] (1) A first aspect of the present disclosure is an information providing apparatus including: a blood information acquisition unit that acquires blood information indicating a state of blood collected from a donor; a determination unit that determines the health state of the donor based on the blood information; and an information providing processing unit that executes processing for providing information indicating a result of the determination by the determination unit to the donor.

[0007] According to such a configuration, information indicating the health state of the donor who has undergone blood collection is provided to the donor. This improves the donor's health awareness.

Brief Description of Drawings

[0027] [Figure 1] FIG. 1 is a diagram illustrating a schematic configuration of a blood collection system according to an embodiment. [Figure 2] FIG. 2 is a flowchart of an information providing method according to an embodiment.

Mode for Carrying Out the Invention

[0028] In the following description, a program (computer program, computer software) is also referred to as a computer program product. A computer program product is not limited to a program stored in a storage medium (recording medium), and also includes a program transmitted, distributed, and downloaded via a network such as the Internet.

[0029] (One Embodiment) FIG. 1 is a diagram illustrating a schematic configuration of a blood collection system 10 according to an embodiment.

[0030] The blood collection system 10 is a system comprising a blood collection device 12, a sensor unit 14, and an information providing device 16. The blood collection device 12 and the information providing device 16 may be separate devices that can communicate with each other, but are not limited to this. The blood collection device 12 and the information providing device 16 may be integrated. For example, the information providing device 16 may be provided in the blood collection device 12.

[0031] The blood collection device 12 is a device provided for performing blood collection. The blood collection device 12 is, for example, a vacuum blood collection device that uses negative pressure to collect blood. The blood collection device 12 may be installed in a facility such as a blood donation room (blood donation facility 100) where blood donation takes place. The blood collection device 12 comprises a housing 18 and a lid 20.

[0032] The housing 18 has a storage chamber 18a, which is a chamber capable of storing a blood collection bag 22. The blood collection bag 22 is a blood bag that contains collected blood. A tube 24 is connected to the blood bag, such as the blood collection bag 22. The tube 24 connects, for example, a blood collection needle (not shown) that is inserted into the donor to the blood collection bag 22. The tube 24 is translucent (transparent). The tube 24 may also be flexible.

[0033] The lid 20 covers the storage chamber 18a in an openable and closable manner. In this case, the lid 20 may be attached to one or more hinges 18b provided on the housing 18, for example. The lid 20 may be translucent (transparent). This allows the blood collection bag 22 stored in the storage chamber 18a to be visible through the lid 20. The blood collection device 12 may further be provided with a sealing member (not shown). This sealing member seals the gap between the lid 20 and the housing 18 when the storage chamber 18a is covered by the lid 20.

[0034] The blood collection device 12 has a pre-formed opening 12a for the discharge of the tube 24. The opening 12a is formed in the housing 18 or the lid 20. When a blood collection bag 22 is stored in the storage chamber 18a, the tube 24 connected to the blood collection bag 22 may extend outside the storage chamber 18a. The blood collection device 12 may further include a tube holder 26. The tube holder 26 holds the tube 24 that extends outside the storage chamber 18a.

[0035] The sensor unit 14 is provided on the tube 24. The sensor unit 14 has a sensor housing 28 and one or more sensors (not shown). The sensor housing 28 is a housing that can house one or more sensors and can be attached to the tube 24. The one or more sensors are detection devices (detection device group) for acquiring blood information. Blood information is information indicating the condition of the blood being collected. A more detailed explanation of blood information will be given later. At least one sensor may be disposed inside the tube 24.

[0036] The sensor unit 14 is mounted on the tube 24 in such a way as not to obstruct the flow of blood inside the tube 24. For example, as shown in Figure 1, the sensor housing 28 may have a cylindrical shape. In other words, the sensor housing 28 may have a through hole. The tube 24 can be passed through this through hole. In this way, the sensor unit 14 is attached to the outer circumference of the tube 24 in such a way as not to obstruct the flow of blood inside the tube 24.

[0037] The sensor housing 28 may have a first partial housing 281 and a second partial housing 282. In this case, the first partial housing 281 and the second partial housing 282 are combined to form the sensor housing 28. The first partial housing 281 is provided with an engaging portion 28a, such as an engaging claw. The second partial housing 282 is provided with a locking portion 28b into which the engaging portion 28a can be locked. By locking the engaging portion 28a with the locking portion 28b, a cylindrical sensor housing 28 can be formed. Furthermore, by locking the engaging portion 28a with the locking portion 28b, the sensor unit 14 can be detachably locked to the tube 24.

[0038] Blood information includes at least one of the following: flow rate information, color information, concentration information, and viscosity information.

[0039] The flow velocity information indicates the flow velocity of blood flowing toward a blood bag such as the blood collection bag 22. More specifically, the flow velocity information indicates, for example, the flow velocity of blood (whole blood) flowing from the blood collection needle (donor) toward the blood collection bag 22. The flow velocity information may also indicate the degree of stability of the blood flow. That is, the flow velocity information may indicate the amount of fluctuation, the rate of fluctuation, etc., of the blood flow velocity of blood flowing toward a blood bag such as the blood collection bag 22 over a predetermined period. The sensor unit 14 may have a flow velocity sensor (flow sensor) in order to output a detection signal corresponding to the blood flow velocity. The flow sensor may be an ultrasonic flow sensor or other sound wave type flow sensor. In that case, the flow sensor, which is an ultrasonic flow sensor, may be disposed outside the tube 24.

[0040] The color information is information indicating the color of the blood. The sensor unit 14 may have an optical sensor to output a detection signal corresponding to the color of the blood. The optical sensor includes, for example, a light-emitting unit that emits light toward the tube 24 and a light-receiving unit that receives the light that has passed through the tube 24. The light-emitting unit has a light-emitting element (light-emitting circuit) that emits predetermined light including, for example, red light and infrared light. In contrast, the light-receiving unit has a light-receiving element (light-receiving circuit) that receives the light that has passed through the tube 24 (blood). Based on the ratio of the red light component and the infrared light component that have passed through the blood and reached the light-receiving element, the optical sensor can detect the color of the blood.

[0041] Concentration information is information indicating the concentration (thickness) of blood. Blood concentration can be detected based on the amount of light transmitted through tube 24 (blood). This amount of light transmission can be derived, for example, based on the amount of light emitted by the light-emitting element described above and the amount of light received by the light-receiving element described above. Therefore, blood concentration may be detected, for example, by the light sensor described above.

[0042] Viscosity information is information indicating the viscosity of blood. The sensor unit 14 may have a viscosity sensor in order to output a detection signal corresponding to the viscosity of the blood.

[0043] The information providing device 16 is an electronic device (computer) that can determine the health status of a donor based on blood information and provide the determination result to the donor. The information providing device 16 may be implemented by a relatively small computer such as a microcontroller. The information providing device 16 comprises a storage unit 30 and an arithmetic unit 32.

[0044] The storage unit 30 includes one or more memory devices. The storage unit 30 includes non-volatile memory such as ROM (Read Only Memory), flash memory, or magnetic disk. Non-volatile memory is a storage medium that stores programs, tables, maps, etc., on a non-temporary basis. The storage unit 30 may also include volatile memory such as RAM (Random Access Memory). At least a portion of the storage unit 30 may be implemented by a storage medium such as USB (Universal Serial Bus) memory, a memory card, or an optical disk.

[0045] The arithmetic unit 32 includes a processing circuit capable of performing arithmetic processing. This processing circuit may have one or more processors. For example, the processing circuit may have a CPU (Central Processing Unit), a GPU (Graphics Processing Unit), etc. The processing circuit may have an IC (Integrated Circuit) or discrete devices.

[0046] The calculation unit 32 includes a blood information acquisition unit 34, an attribute information acquisition unit 36, an evaluation criteria setting unit 38, a determination unit 40, and an information provision processing unit 42. The blood information acquisition unit 34, the attribute information acquisition unit 36, the evaluation criteria setting unit 38, the determination unit 40, and the information provision processing unit 42 are realized by the processing circuit described above. For example, the blood information acquisition unit 34, the attribute information acquisition unit 36, the evaluation criteria setting unit 38, the determination unit 40, and the information provision processing unit 42 are realized by a program stored in the storage unit 30 being executed by the processor of the calculation unit 32. At least one of the above-mentioned IC and discrete device may realize at least a part of the blood information acquisition unit 34, the attribute information acquisition unit 36, the evaluation criteria setting unit 38, the determination unit 40, and the information provision processing unit 42.

[0047] The blood information acquisition unit 34 acquires the donor's blood information. The blood information acquisition unit 34 can acquire blood information based on detection signals output from the sensor unit 14 (one or more sensors) described above.

[0048] The attribute information acquisition unit 36 ​​acquires attribute information of the donor corresponding to the blood information. Attribute information is information that indicates the attributes of the donor. For example, the donor's gender, actual age, etc., are indicated by the attribute information. Information indicating the results of various tests that the donor may undergo in advance may also be included in the attribute information. For example, information indicating the donor's hemoglobin concentration, hematocrit value, etc., which are measured in advance, may be included in the attribute information.

[0049] Attribute information may be provided to the blood collection system 10 in advance by the donor. The attribute information provided in advance is stored, for example, in the storage unit 30 of the information providing device 16. An external storage device (such as a server) that can communicate with the information providing device 16 may also store the attribute information provided by the donor. In that case, the information providing device 16 may obtain the donor's attribute information from the external storage device.

[0050] The evaluation criteria setting unit 38 sets evaluation criteria based on attribute information acquired by the attribute information acquisition unit 36. These evaluation criteria are for determining the health status of the donor. The evaluation criteria setting unit 38 sets at least one of the following criteria: flow rate evaluation criteria, color evaluation criteria, concentration evaluation criteria, and viscosity evaluation criteria, depending on, for example, the donor's sex, actual age, hemoglobin concentration, and hematocrit value.

[0051] The flow velocity evaluation criteria are the criteria (threshold, predetermined range) for evaluating the blood flow velocity. These criteria can be predetermined based, for example, on statistical information (average values, etc.) of blood flow velocity for each sex or age group. Furthermore, the flow velocity evaluation criteria may also include criteria for evaluating the stability of blood flow (allowable fluctuation range of flow velocity, etc.).

[0052] The color evaluation criteria are evaluation criteria (thresholds, predetermined ranges) for color intensity, which is the degree to which blood color is represented. These color evaluation criteria can be predetermined, for example, based on statistical information (average values, etc.) of color intensity for each gender or age group.

[0053] Concentration evaluation criteria are standards (thresholds, predetermined ranges) for evaluating blood concentration. These criteria can be predetermined based, for example, on statistical information (average values, etc.) of concentration levels by sex or actual age.

[0054] Viscosity evaluation criteria are standards (thresholds, predetermined ranges) for evaluating the viscosity of blood. Viscosity evaluation criteria can be predetermined based, for example, on statistical information (average values, etc.) of viscosity by sex or actual age.

[0055] The evaluation criteria may be set according to the age group to which the donor belongs. In that case, the evaluation criteria setting unit 38 identifies the age group to which the donor belongs based on the donor's actual age.

[0056] The determination unit 40 determines the donor's health status based on the blood information acquired by the blood information acquisition unit 34 and the evaluation criteria set by the evaluation criteria setting unit 38. For example, the determination unit 40 compares the blood flow velocity indicated by the blood information with the flow velocity evaluation criteria and evaluates (scores) the degree of goodness of the flow velocity. In this case, the determination unit 40 evaluates the degree of goodness of the flow velocity more highly, for example, the smaller the degree of discrepancy between the blood flow velocity indicated by the blood information and the threshold, predetermined range, etc., indicated by the flow velocity evaluation criteria, but is not limited to this. For example, even if the degree of discrepancy is relatively large, if the blood flow velocity indicated by the blood information is close to the flow velocity evaluation criteria corresponding to a younger age group than the donor, the determination unit 40 may evaluate the degree of goodness of the flow velocity more highly. More specifically, for example, if the blood flow velocity of a donor in their 40s deviates from the predetermined range corresponding to those in their 40s, but falls within the predetermined range corresponding to those in their 20s, the determination unit 40 may highly evaluate the quality of the blood flow velocity. The determination unit 40 may also evaluate (score) the degree of stability of the blood flow.

[0057] The judgment unit 40 can also evaluate (score) the degree of goodness of the blood's color (color intensity), concentration, viscosity, etc., based on comparison with corresponding evaluation criteria. The evaluation results of the degree of goodness of each item (blood flow rate, color intensity, concentration, viscosity, etc.) are identified as the result of determining the donor's health status.

[0058] Furthermore, if the judgment unit 40 evaluates the degree of goodness for multiple items based on blood information, it may perform an overall evaluation based on the evaluation results of those multiple items. For example, based on the evaluation results of two or more items from blood flow velocity, color intensity, concentration, and viscosity, the judgment unit 40 may determine the donor's blood age (which age group's average blood condition the donor's blood condition corresponds to). When performing an overall evaluation for multiple items, the judgment unit 40 may calculate representative values ​​for the multiple degrees of goodness (scores) scored for each item. For example, the judgment unit 40 calculates representative values ​​for the score of the item "blood flow velocity," the score of the item "blood color intensity," the score of the item "blood concentration," and the score of the item "blood viscosity." In this case, the representative values ​​are the average value, median value, etc. of the multiple scores. When performing an overall evaluation for multiple items, the judgment unit 40 may determine the donor's blood age based on the maximum or minimum value of the multiple scores calculated for each item.

[0059] The information provision processing unit 42 performs processing to provide the information to the donor. The information provided is information indicating the result of the determination by the determination unit 40 (the donor's health status). The information provision processing unit 42 performs processing to print out the information provided. In this case, the information provision processing unit 42 outputs a command to the printer 44 (see also Figure 1), which is connected to the information provision device 16 via a network, for example, to print a document on which the information provided is printed.

[0060] The information provision processing unit 42 may perform processing to display the provided information on a predetermined display device. The predetermined display device is, for example, a monitor of a PC (Personal Computer) appropriately installed in the blood donation facility 100, an electronic bulletin board, etc., but is not limited to these. For example, the predetermined display device may be an information and communication terminal (tablet terminal, smartphone, etc.) held by the staff of the blood donation facility 100 or a donor.

[0061] The information providing device 16 may further perform processing to store the provided information in the storage unit 30 or the external storage device described above. In this case, the provided information may be stored in association with the identification information of the donor to whom the provided information is provided, the attribute information of the donor (described above), etc. The provided information stored in the storage unit 30 or the external storage device described above may be provided to the donor, for example, upon the donor's request.

[0062] The above describes one embodiment of the blood collection system 10 (information providing device 16), but at least a portion of the blood information may be detected by sensors provided in the blood collection bag 22 or the blood collection device 12. In addition, the determination unit 40 may determine the health status of multiple donors using predetermined general evaluation criteria. In that case, the attribute information acquisition unit 36, the evaluation criterion setting unit 38, etc. may be omitted as appropriate.

[0063] Figure 2 is a flowchart of an information provision method according to one embodiment.

[0064] The information providing device 16 can execute the information providing method shown in Figure 2. For example, the information providing device 16 (computer) executes the information providing method shown in Figure 2 by having the arithmetic unit 32 (processor) execute a program stored in the memory unit 30. As shown in Figure 2, the information providing method includes a blood information acquisition step S1, an attribute information acquisition step S2, an evaluation criterion setting step S3, a determination step S4, and an information providing processing step S5.

[0065] In the blood information acquisition step S1, the blood information acquisition unit 34 acquires blood information. The blood information acquisition step S1 is performed before the determination step S4. The blood information acquisition step S1 may also be performed after the attribute information acquisition step S2 or the evaluation criteria setting step S3.

[0066] In the attribute information acquisition step S2, the attribute information acquisition unit 36 ​​acquires attribute information. The evaluation criteria setting step S3 is performed after the attribute information acquisition step S2 and before the judgment step S4. In the evaluation criteria setting step S3, the evaluation criteria setting unit 38 sets evaluation criteria based on the attribute information.

[0067] In the determination step S4, the determination unit 40 determines the donor's health status based on the blood information and evaluation criteria. This generates the aforementioned donation information. In the information provision processing step S5, the information provision processing unit 42 performs processing to provide the donation information to the donor. Thus, the information provision method shown in Figure 2 is completed.

[0068] The information-providing device 16 (blood sampling device 12) described above has the following effects, for example.

[0069] The information providing device 16 comprises a determination unit 40 and an information provision processing unit 42. The determination unit 40 determines the health status of the donor based on blood information, which is information indicating the condition of the blood being collected. The result of the determination by the determination unit 40 is provided to the donor by the information provision processing unit 42. In this way, the information providing device 16 encourages donors to improve their health awareness. Furthermore, since the information providing device 16 provides information to donors who have had blood collected (donated), it can encourage donors who have become interested in their health status to revisit the blood donation facility 100. In other words, the information providing device 16 can encourage donors to donate blood repeatedly.

[0070] The information providing device 16 includes a blood information acquisition unit 34. The blood information described above is acquired by the blood information acquisition unit 34. The blood information acquisition unit 34 acquires blood information based on detection signals from a sensor (sensor unit 14) provided on a tube 24 connecting the blood collection needle inserted into the donor and the blood bag (blood collection bag 22). Since blood inevitably flows from the puncture needle towards the blood bag, the blood flow rate and other parameters can be suitably detected by the sensor.

[0071] The information providing device 16 further includes an attribute information acquisition unit 36. The attribute information acquisition unit 36 ​​acquires the donor's attribute information. The determination unit 40 can determine the donor's health status based on the donor's attribute information. This allows the information providing device 16 to determine the donor's health status in more detail or with greater accuracy. For example, the determination unit 40 can evaluate the donor's health status based on blood information and evaluation criteria predetermined according to the donor's actual age or the age group to which the donor belongs, as indicated by the donor's attribute information.

[0072] The attribute information acquisition unit 36 ​​acquires the donor's attribute information from the storage unit. In this case, the storage unit may be a storage unit 30 provided in the information processing device, or it may be an external storage device such as a server device.

[0073] The information provision processing unit 42 may perform processing to print out the result of the determination by the determination unit 40. This allows, for example, a donor who has had blood collected at a blood donation facility 100 to quickly receive a document (printed material) with the result of the determination by the information provision device 16 at the blood donation facility 100.

[0074] The information providing device 16 may be provided in the blood collection device 12, such as a vacuum blood collection device. This provides a blood collection device 12 equipped with the functions of the information providing device 16.

[0075] The sensor unit 14 may be detachably secured to the tube 24. This allows the sensor unit 14, which houses one or more sensors, to be easily attached to and detached from the tube 24.

[0076] While this disclosure has been described in detail, it is not limited to the individual embodiments described above. These embodiments can be added, replaced, modified, partially deleted, etc., in any way that does not depart from the gist of this disclosure or from the spirit of this disclosure derived from the claims and their equivalents. These embodiments can also be implemented in combination. For example, the order of operations and processes in the embodiments described above are given as examples only and are not limited thereto. The same applies when numerical values ​​or mathematical formulas are used in the description of the embodiments described above. [Explanation of symbols]
