Description

[Technical field]

[0001] The present invention relates to a blood collection management system and a blood collection confirmation device for managing blood collected during blood collection operations in hospitals, medical examination institutions, etc. [Background technology]

[0002] In blood collection operations carried out in hospitals, health examination institutions, etc., blood collection tubes with labels with optical codes attached thereto are used, and identification information of blood recipients and information of blood collection workers are managed according to the information stored in the optical codes. For example, Patent Document 1 proposes a label with an RFID tag as a label to be attached to blood collection tubes. If such a label with an RFID tag is used, information can be read collectively from the RFID tags of the labels attached to each blood collection tube while multiple blood collection tubes are stored in a tray, and therefore, compared to the optical code label, there is an advantage that blood collection operations can be made more efficient. Furthermore, for example, Patent Document 2 proposes a system for tracking and managing the behavior of a blood collection tube to which the RFID tag-equipped label is affixed. In this configuration, a transceiver for transmitting and receiving signals (information) to and from the RFID tag of the label is installed in the movement path of the blood collection tube, and the behavior of the blood collection tube can be tracked and managed by confirming the position information of the blood collection tube via the transceiver.

[0003] [Patent Document 1] JP 2018-49095 A [Patent Document 2] JP 2016-75565 A Summary of the Invention [Problem to be solved by the invention]

[0004] In the blood collection operation described above, generally, multiple blood collection tubes are used for each blood recipient, and a predetermined amount of blood is collected from each blood collection tube. The amount of blood to be collected in each blood collection tube is set to a lower limit amount necessary for clinical testing. In such blood collection operation, generally, a vacuum blood collection tube is used. This vacuum blood collection tube is capable of receiving an appropriate amount of blood (an amount equal to or greater than the lower limit amount) by the negative pressure inside. However, since some blood recipients have difficulty bleeding, it may be difficult to collect an appropriate amount of blood only by the function (negative pressure) of the vacuum blood collection tube. In such a case, the blood collection worker visually judges whether the amount of collected blood has reached the lower limit amount, and after the blood collection operation is once completed, an operation is performed to judge whether the amount of collected blood is sufficient for the lower limit amount. If the amount of collected blood does not meet the lower limit amount, the blood recipient is called again to perform the blood collection operation. However, such an operation process places a burden on both the blood collection worker and the blood recipient, and increases the time required for blood collection. This was one of the reasons why outpatient blood collection became crowded. Furthermore, if the amount of collected blood does not reach the lower limit and re-collection is not possible, it may be impossible to carry out necessary clinical tests, in which case the previous blood collection operation itself becomes a waste. This may cause distrust in the blood collection operation and medical institutions among the subjects, or may lower the image of the medical institutions.

[0005] Meanwhile, as described above, in a general blood collection operation, blood is collected into multiple blood collection tubes for each blood recipient. The number of blood collection tubes may differ depending on the blood recipient, and the blood collection worker is required to check the number of blood collection tubes required for each blood recipient before carrying out the blood collection operation. However, in the blood collection operation, although the number of blood collection tubes is checked at the start of blood collection, there has been a problem in which the blood collection tubes after blood collection are mistakenly placed in the disposal box. If a blood collection tube is mistakenly discarded, it takes time and effort to search for the blood collection tube, which places a burden on the blood collection worker and hospital staff. It is difficult to solve the problem of erroneous disposal with the RFID label of the conventional configuration. That is, the RFID label only enables transmission and reception of signals (information) with the blood collection tube to which the label is attached, but cannot detect the erroneous disposal. In addition, the conventional system for managing the behavior of blood collection tubes can track blood collection tubes discarded in a disposal box to some extent, but in addition to the time and effort required to find the disposal box, there is also the problem of an infection risk from touching the disposal box.

[0006] The present invention proposes a blood collection management system and a blood collection confirmation device that can confirm whether the amount of collected blood has reached the lower limit during blood collection, thereby preventing problems caused by an insufficient amount of collected blood. [Means for solving the problem]

[0007] The first invention of the present invention is a blood collection confirmation device including an information reading means for reading identification information from the information storage means of a blood collection tube to which a label having an information storage means for storing identification information is affixed, a blood collection weight measuring means for measuring the weight of blood contained in the blood collection tube, and an acquired information transmitting means for transmitting the identification information read by the information reading means and weight information measured by the blood collection weight measuring means, and a blood collection management device that is capable of transmitting and receiving information to the blood collection confirmation device and manages the identification information, wherein the blood collection management device includes a blood collection amount determining means for determining whether or not the blood collection weight obtained from the weight information reaches a predetermined threshold weight value when the blood collection management device receives the identification information and weight information from the blood collection confirmation device, and an evaluation information transmitting means for transmitting blood collection evaluation information including the determination result by the blood collection amount determining means to the blood collection confirmation device, and wherein the blood collection confirmation device includes an evaluation information notifying means for executing a notification indicating the blood collection evaluation information when the blood collection confirmation device receives the blood collection evaluation information from the blood collection management device.

[0008] Here, the identification information suitably used is information necessary to identify the person to whom blood is to be collected (name, address, gender, ID number, etc.), information necessary to identify the blood collection operator (name, address, gender, ID number, etc.), information indicating the clinical tests of the person to whom blood is to be collected, information on the amount of blood to be collected from the person to whom blood is to be collected, etc., and may be any one or more of these, or all of these. The information storage means is preferably an RFID tag or an optical code, such as a bar code or a QR code (registered trademark). The blood collection weight measuring means may be any means capable of substantially measuring the weight of blood collected in the blood collection tube (hereinafter referred to as the blood collection weight). For example, it may be provided with any one of a function of directly measuring the blood collection weight, a function of measuring the weight of the blood collection tube after blood collection (blood collection tube containing blood), and a function of measuring the weight change before and after measuring the blood collection tube. Here, in a configuration provided with a function of measuring the weight of the blood collection tube after blood collection, the weight of the blood collected in the blood collection tube can be obtained by confirming the weight of only the blood collection tube in advance. On the other hand, in a configuration provided with a function of measuring the weight change before and after measuring the blood collection tube, the weight of the blood collected in the blood collection tube can be obtained from the weight change and the weight of only the blood collection tube. The acquired information transmission means is not limited to a configuration that transmits the weight information measured by the blood collection weight measurement means as it is, but may be a configuration that performs calculation processing on the measured weight and transmits it. That is, as described above, when the blood collection weight measurement means measures the weight of the blood collection tube after blood collection, the acquired information transmission means may be a configuration that transmits the weight information, or may be a configuration that calculates the blood collection weight from the weight information and transmits it. Similarly, when the blood collection weight measurement means measures the weight change before and after measuring the blood collection tube, the acquired information transmission means may be a configuration that transmits the weight change information, or may be a configuration that calculates the blood collection weight from the weight change and transmits it.

[0009] According to this configuration, immediately after the blood collection operation, the blood collection confirmation device acquires the identification information of the blood collection tube and the information on the collected blood weight, and a notification is made showing the blood collection evaluation information evaluated by the blood collection management device based on the identification information and the information on the collected blood weight, so that the blood collection worker can accurately know whether the collected blood weight has reached the threshold weight value or not through the notification. As a result, if the amount of collected blood is insufficient, re-collection of blood can be performed immediately. In this manner, in the configuration of the present invention, the blood collection evaluation information is notified relatively quickly after the blood collection operation, so that the blood collection worker can know whether the amount of collected blood is insufficient or not during the series of blood collection operations from the start of blood collection to the end. Therefore, there is no need to call the person to be collected when the amount of collected blood is insufficient, and the time and burden required for re-collection of blood can be significantly reduced. In addition, the burden on the person to be collected for re-collection performed due to insufficient amount of collected blood can be reduced, and problems caused by re-collection of blood can be suppressed. Furthermore, because the amount of collected blood can be determined accurately and stably, the accuracy of determination is dramatically improved compared to the conventional visual inspection described above, and the occurrence of a situation in which clinical testing cannot be performed due to an insufficient amount of collected blood can be prevented, which can prevent distrust in blood collection work and a negative image of medical institutions.

[0010] In addition, in this configuration, it is essential for the blood collection evaluation information to be notified by acquiring identification information and collected blood weight information by the blood collection confirmation device after blood collection. That is, in order to acquire blood collection evaluation information, the blood collection tube must be the subject of acquiring identification information and collected blood weight information by the blood collection confirmation device. By including the operation of the blood collection confirmation device in the blood collection work process in this way, it is possible to prevent the blood collection tube from being erroneously disposed of in the disposal box. This can reduce the effort and time required for the search work caused by the erroneous disposal of the blood collection tube, and also reduce the risk of infection caused by touching the disposal box.

[0011] The second invention of the present invention is a blood collection confirmation device comprising an information reading means for reading identification information from the information storage means of a blood collection tube to which a label having an information storage means storing identification information is affixed, and a blood collection weight measuring means for measuring the weight of blood contained in the blood collection tube; and a blood collection management device that is capable of transmitting and receiving information to the blood collection confirmation device and manages the identification information, wherein the blood collection management device comprises a determination information transmitting means for transmitting, to the blood collection confirmation device, determination information including a threshold weight value used to determine the amount of blood collected, upon the establishment of a preset threshold information acquisition condition, and the blood collection confirmation device comprises a blood collection amount determination means for determining whether the weight of blood measured by the blood collection weight measuring means reaches the threshold weight value of the determination information received from the blood collection management device, and an evaluation information notification means for executing an notification showing the determination result by the blood collection amount determination means.

[0012] Here, the identification information, the information storage means, and the collected blood weight measuring means are the same as those in the first invention described above. As the threshold information acquisition condition, for example, a predetermined timing set based on the scheduled blood collection date and time, or receiving identification information of the blood collection recipient from the blood collection management device or a device for confirming the blood collection recipient, etc., are preferably used. Specific examples in the latter case include the blood collection management device receiving identification information of the blood collection recipient from a reception device installed at the reception desk of a hospital or health examination institution, receiving identification information read from the information storage means of the blood collection tube before blood collection from a reading device installed at the blood collection site, receiving identification information read from the information storage means of the blood collection tube by the information reading means of the blood collection confirmation device from the blood collection confirmation device, etc.

[0013] In this configuration, the blood collection confirmation device uses the threshold weight value obtained from the blood collection management device to determine the weight of blood measured by the blood collection weight measurement means and notifies the result of the determination. As in the first invention, the blood collection confirmation device obtains the identification information of the blood collection tube and the information on the collected blood weight immediately after the blood collection operation, so that the blood collection operator can accurately know from the notification whether the collected blood weight has reached the threshold weight value. Therefore, the configuration of the second invention also has the same effects as the first invention described above.

[0014] The third invention of the present invention is a blood collection confirmation device comprising: a blood collection tube inlet into which a blood collection tube with a label having an information storage means storing identification information can be inserted; information reading means for reading the identification information stored in the information storage means from the blood collection tube inserted from the blood collection tube inlet; blood collection weight measuring means for measuring the weight of blood contained in the blood collection tube from which the identification information is read by the information reading means; information transmission means for transmitting the identification information read by the information reading means and the weight information measured by the blood collection weight measuring means to a blood collection management device that manages the identification information; and evaluation information informing means for informing of the blood collection evaluation information when blood collection evaluation information evaluated based on the identification information and the weight information transmitted by the information transmission means is received from the blood collection management device. Here, the identification information, the information storage means, the blood collection weight measuring means, and the information transmission means are the same as those of the blood collection management system of the first invention described above.

[0015] In this configuration, since it is applied to the blood collection confirmation device constituting the blood collection management system of the first invention described above, it can achieve the same effects as the blood collection management system.

[0016] That is, since the blood collection evaluation information is notified based on the insertion of the blood collection tube from the blood collection tube insertion port of the blood collection confirmation device, the blood collection operator can accurately know whether the collected blood weight has reached the threshold weight value through the notification of the blood collection evaluation information by inserting the blood collection tube after blood collection. In this way, the blood collection operator can know whether the amount of collected blood is insufficient in a relatively short time after blood collection, so that the time and burden required for re-collection of blood can be significantly reduced, and the burden on the person to whom blood is collected can be reduced. Therefore, trouble caused by re-collection of blood can be suppressed. Furthermore, since the judgment accuracy is dramatically improved compared to the conventional visual inspection described above, it is possible to suppress the occurrence of a situation in which clinical tests cannot be performed due to an insufficient amount of collected blood, and it is possible to suppress distrust in blood collection work and a decline in the image of medical institutions. In addition, in this configuration, it is essential to insert the blood collection tube into the blood collection tube insertion port of the blood collection confirmation device after blood collection in order to notify the blood collection evaluation information. This makes it possible to prevent the blood collection tube from being mistakenly disposed of in the disposal box, thereby reducing the labor and time required for searching for the blood collection tube due to the mistaken disposal, and also reducing the risk of infection caused by touching the disposal box.

[0017] A fourth invention of the present invention is a blood collection confirmation device comprising: a blood collection tube inlet into which a blood collection tube having a label affixed thereto having an information storage means storing identification information; information reading means for reading the identification information stored in the information storage means from the information storage means of the blood collection tube inserted from the blood collection tube inlet; blood collection weight measuring means for measuring the weight of blood contained inside the blood collection tube from which the identification information is read by the information reading means; blood collection amount determination means for determining whether the weight of blood measured by the blood collection weight measuring means reaches a threshold weight value transmitted from a blood collection management device that manages the identification information; and evaluation information notification means for issuing a notification showing the result of the determination made by the blood collection amount determination means.

[0018] Here, the identification information, the information storage means, and the collected blood weight measuring means are the same as those in the blood collection management system of the second invention described above. The threshold weight value is used to determine the amount of collected blood, as in the second invention. In the configuration of the fourth invention, it is preferable to have a configuration including a determination information acquisition means for receiving determination information including the threshold weight value from the blood collection management device and acquiring the threshold weight value from the received determination information.

[0019] In this configuration, since it is applied to the blood collection confirmation device constituting the blood collection management system of the second invention, it can achieve the same effects as the blood collection management system, or in other words, it achieves the same effects as the blood collection confirmation device of the third invention.

[0020] In the blood collection confirmation device of the third or fourth invention described above, a blood collection tube is used whose label information storage means is an optically readable optical code, and the information reading means is proposed to include a support and change means for supporting the blood collection tube inserted from the blood collection tube insertion port at a predetermined detection position and changing it circumferentially at the detection position, and an optical code reading means for reading identification information stored in the optical code from the optical code of the blood collection tube supported at the detection position by the support and change means.

[0021] Here, the detection position indicates a position where the optical code on the label of the blood collection tube at the detection position can be read by the optical code reading means, and is set within a range where the optical code can be read by the optical code reading means. In other words, the detection position indicates a range where the blood collection tube can be read by the optical code reading means when the blood collection tube is lying down, and may be set so that the blood collection tube can be moved within that range.

[0022] In this configuration, the support fluctuating means fluctuates the blood collection tube in the circumferential direction at the detection position, displacing the optical code of the label affixed to the blood collection tube to a circumferential position where the optical code reading means can read it, so that the optical code of the label can be read accurately and stably by the optical code reading means. Thus, according to this configuration, when a blood collection tube with an optically coded label is inserted from a blood collection tube insertion port, the optical code of the blood collection tube supported at the detection position can be read, and the occurrence of a problem in which the optical code cannot be read can be suppressed. Therefore, the effects of the present invention (the third and fourth inventions) described above can be exhibited more stably.

[0023] In addition, since this configuration uses a blood collection tube with a label having an optical code attached thereto, it has the excellent advantage of being able to reduce costs compared to the case in which the RFID tag is used.

[0024] In the blood collection confirmation device of the present invention described above, the support change means of the information reading means includes a blood collection tube support member that can be converted between a supported state in which the blood collection tube inserted from the blood collection tube insertion port is supported at the detection position in a horizontally lying state so as to be freely rotatable in the circumferential direction, and a descended state in which the blood collection tube is moved downward, and that is arranged to be swingable in the left-right direction approximately perpendicular to the longitudinal direction of the blood collection tube, and a drive means that executes an operation of swinging the blood collection tube support member in the left-right direction while maintaining the blood collection tube support member in the supported state, and an operation of converting the blood collection tube support member between the supported state and the descended state, and the blood collection weight measuring means is provided below the blood collection tube support member and includes a table on which a tray containing the blood collection tube moved from the blood collection tube support member is placed, and a weight measuring means that measures the weight of the blood collection tube contained in the tray on the table or the weight of the blood collected in the blood collection tube.

[0025] Here, the weight measuring means may directly measure the weight of the blood collection tube (blood collection tube containing blood after blood collection) or the weight of the collected blood in the blood collection tube, or may measure the weight change before and after the blood collection tube is accommodated in the tray. In the case where the weight measuring means is configured to measure the weight of the blood collection tube after blood collection or the weight change before and after the tube is accommodated in the tray, it is preferable that the collected blood weight measuring means has a function of acquiring the weight of the collected blood contained in the blood collection tube from the measured weight or weight change.

[0026] In this configuration, the blood collection tube supported at the detection position can be moved in its circumferential direction by swinging the blood collection tube support member from side to side while supported, so that the optical code on the label attached to the blood collection tube can be made to face the optical code reading means, and the optical code reading means can accurately and stably read the optical code on the label. Furthermore, this configuration can store the blood collection tube supported by the blood collection tube support member in a tray by changing the position of the blood collection tube support member to the lowered position, and can measure the weight of the blood collection tube or the weight of blood collected in the blood collection tube. In this way, this configuration can read the optical code by only swinging the blood collection tube support member, which is a relatively simple operation, and can store the blood collection tube in the tray and measure the weight by only changing the position of the blood collection tube support member to the lowered position.

[0027] In the blood collection confirmation device of the present invention described above, it is proposed that the information reading means is equipped with an operation control means including a swing control process for swinging the blood collection tube support member while maintaining it in a supported state when a predetermined detection start condition is satisfied, and a lowering operation process for converting the blood collection tube support member from the supported state to a lowered state when the optical code reading means reads identification information from the optical code of the blood collection tube supported at the detection position after swinging by the swing control process has started.

[0028] Here, the detection start condition can be preferably established by the operation of the blood collection operator, established by the detection of the blood collection tube, etc. Specifically, in the former case, it can be set that a switch or button that can be operated by the blood collection operator is operated. On the other hand, in the latter case, it can be set that a sensor or a camera is provided to detect the blood collection tube inserted into the blood collection tube insertion port, or a sensor or a camera to detect the blood collection tube supported by the blood collection tube support member, and the blood collection tube is detected by the sensor or the camera.

[0029] According to this configuration, when the detection start condition is satisfied, the optical code of the blood collection tube can be read and the blood collection tube can be accommodated in a tray on the table. In this way, the reading of the optical code and the accommodation of the tray can be performed automatically, and the burden on the blood collection operator required for the reading and the accommodation of the tray can be reduced.

[0030] In this configuration, the lowering operation process is proposed to stop the swinging of the blood collection tube support member and maintain the supported state when the optical code reading means cannot read the optical code. With this configuration, it is possible to prevent the blood collection tube from being stored in the tray when the blood collection tube cannot be supported at the detection position of the blood collection tube support member, when the blood collection tube cannot move in the circumferential direction, or when the label of the blood collection tube is incomplete.

[0031] In the present configuration according to the third invention, the collected blood weight measuring means is preferably provided with a weight measuring process for measuring the weight of collected blood in the blood collection tube moved from the blood collection supporting member as the blood collection supporting member is changed to the lowered state.Furthermore, the acquired information transmitting means is preferably provided with an acquired information processing process for transmitting information on the collected blood weight and identification information read from the optical code of the blood collection tube to the blood collection management device when the collected blood weight measuring means measures the weight of collected blood in the blood collection tube. According to this configuration, when the detection start condition is satisfied, a series of operations from the swinging of the blood collection support member to the transmission of the identification information and the collected blood weight information is automatically executed, so that the blood collection operator can receive the blood collection evaluation information by simply inserting the blood collection tube into the blood collection tube insertion port. Therefore, the burden on the blood collection operator can be further reduced.

[0032] On the other hand, in this configuration which is dependent on the fourth invention, it is preferable that the blood collection weight measuring means is equipped with a weight measurement process which measures the weight of blood collected in the blood collection tube moved from the blood collection support member as the blood collection support member is converted to a lowered state, and further, it is preferable that the blood collection amount determining means is configured to determine whether the weight of blood has reached the threshold weight value when both the weight of blood measured by the blood collection weight measuring means and the threshold weight value transmitted from the blood collection management device are obtained. According to this configuration, when the detection start condition is satisfied, a series of operations from the swinging of the blood collection support member to the notification of the result of the blood collection weight is automatically executed, so that the blood collection operator can receive the notification of the blood collection evaluation information simply by inserting the blood collection tube into the blood collection tube insertion port. Therefore, the burden on the blood collection operator can be further reduced. Effect of the Invention

[0033] According to the blood collection management system of the present invention, the blood collection operator can know whether the amount of collected blood is insufficient or not in a relatively short time after collecting blood, and therefore, when the amount of collected blood is insufficient, the time and burden required for re-collection of blood can be significantly reduced. In addition, the occurrence of a situation in which clinical tests cannot be performed due to an insufficient amount of collected blood can be prevented, and therefore, distrust of blood collection work and a negative image of medical institutions among blood collection subjects can be prevented. In addition, erroneous disposal of blood collection tubes can be prevented, and therefore, the burden associated with such erroneous disposal can be reduced.

[0034] The blood collection confirmation device of the present invention is applied to the blood collection management system described above, and therefore can achieve the same effects as those of the blood collection management system. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0036] The embodiments of the present invention will be described with reference to the following Examples 1 to 3. EXAMPLES

[0037] The blood collection management system 1 of this embodiment is for supporting blood collection work by blood collection workers (nurses, etc.) in medical institutions such as hospitals and health checkup institutions. As shown in Fig. 1, the blood collection management system 1 includes a blood collection management server 2, a database 3, and one or more blood collection confirmation devices 5. Here, the blood collection confirmation device 5 is installed in a blood collection room, and the blood collection management server 2 and the database 3 are preferably located near the blood collection room, although there is no particular limitation thereto.

[0038] The blood collection management server 2 is the core of the blood collection management system 1, and is connected to a higher-level system (electronic medical record system) via an in-hospital LAN, and is communicatively connected to the database 3 and blood collection confirmation device 5 via a communication cable. The blood collection management server 2 is equipped with operation means such as a monitor and a keyboard, so that an administrator can update and correct various programs and data (information) at any time. Furthermore, a printer (not shown) is connected, so that various data stored in the database 3 can be printed out.

[0039] The database 3 accumulates and stores various data (information) related to blood collection operations. The data stored in the database 3 is referenced, registered, and updated by the blood collection management server 2 and the like. In this embodiment, the blood collection management server 2 and the database 3 constitute the blood collection management device according to the present invention.

[0040] The blood collection tube 81 used in this embodiment is a so-called vacuum blood collection tube, and as shown in FIG. 9, is composed of a main tube 82 made of transparent glass or plastic and having a bottom and a cylindrical shape, and a cap body 83 that seals the upper opening of the main tube 82. A label 85 on which a barcode 86 is printed is attached to the outer surface of the main tube 82. Here, the label 85 is substantially rectangular in shape with a width shorter than the outer periphery of the main tube 82, and is attached along the circumferential direction of the main tube 82. Therefore, in order to read the barcode 86 on the label 85 with the optical code reader 25 described later, it is necessary to rotate (fluctuate) the blood collection tube 81 in the circumferential direction so that the barcode 86 is within a range that can be read by the optical code reader, and to position the barcode 86 facing the optical code reader 25. In this embodiment, the barcode 86 stores identification information (such as name, sex, ID, etc.) for identifying the subject from whom blood is to be collected.

[0041] 2 to 5, the blood collection confirmation device 5 includes a housing 11 provided with a blood collection tube inlet 12 that opens upward and a tray inlet / outlet 13 that opens forward, and a table 15 on which a tray 80 inserted from the tray inlet / outlet 13 is placed, and a load cell device 16 (see FIG. 8) that measures the weight on the table 15 are disposed inside the housing 11. Furthermore, a blood collection tube support member 31 that supports a blood collection tube 81 inserted from the blood collection tube inlet 12 is disposed above the table 15.

[0042] In this embodiment, the direction in which the tray 80 is inserted and removed through the tray entrance / exit 13 is defined as the front-rear direction, and the lateral direction perpendicular to the front-rear direction is defined as the left-right direction. The side of the tray entrance / exit 13 of the blood collection confirmation device 5 is defined as the front.

[0043] The housing 11 includes a pair of left and right guide plates 21a, 21b arranged in an inverted V-shape facing each other on the upper portion thereof when viewed from the front, and the lower ends of the left and right guide plates 21a, 21b are spaced apart at a predetermined interval in the left-right direction, and the lower ends of the guide plates 21a, 21b form the blood collection tube insertion port 12. The interval of the blood collection tube insertion port 12 is set to a width dimension that allows the blood collection tube 81 to fall and allows an optical code reader to read the barcode 86 of the blood collection tube 81 supported by the blood collection tube support member 31 while the blood collection tube support member 31 is swinging, as described later. In addition, the left and right guide plates 21a, 21b have the function of guiding the blood collection tube 81 to the blood collection tube insertion port 12 when the blood collection tube 81 is inserted into the blood collection tube insertion port 12.

[0044] As shown in FIG. 6, the blood collection tube support member 31 includes left and right raised portions 33, 33 that are raised upward, and a support groove portion 32 that is recessed downward between the raised portions 33, 33, and the left and right raised portions 33, 33 and the support groove portion 32 are connected in the left and right direction. The raised portions 33, 33 and the support groove portion 32 are each formed along the front-rear direction, and the length of each of the front-rear directions is set to be longer than the entire length of the blood collection tube 81. Here, the support groove portion 32 is provided in the approximate center of the blood collection tube support member 31 in the left-right direction, and is configured by a curved surface having an approximately arc-shaped cross section with a larger radius of curvature than the blood collection tube 81. Furthermore, in this embodiment, the depth of the support groove portion 32 (height dimension difference with the apex of the raised portions 33, 33) is set to be slightly smaller than the radius of the blood collection tube 81 (about half of the radius). Such a blood collection tube support member 31 can support the blood collection tube 81 within the support groove portion 32 with the blood collection tube 81 lying horizontally in the front-to-back direction, and can also allow the blood collection tube 81 to rotate freely in the left-to-right direction on the curved surface of the support groove portion 32 while being supported.

[0045] A substantially fan-shaped connecting member 46 having a rotating shaft 42 is connected to the rear end of the blood collection tube support member 31, and the blood collection tube support member 31 can move in an arc shape in the left-right direction according to the rotation of the rotating shaft 42. The rotating shaft 42 is rotatably supported by the housing 11, and its rotation is controlled by a driving device 41 disposed in the housing 11. As shown in FIGS. 2 to 5, the driving device 41 includes a stepping motor 43 capable of rotating forward and backward, and a belt mechanism 44 that transmits the rotation of the stepping motor 43 to the rotating shaft 42 by a timing belt (not shown), and rotates the rotating shaft 42 according to the rotation of the stepping motor 43. That is, by controlling the rotation of the stepping motor 43 of the driving device 41, the blood collection tube support member 31 can be moved in an arc shape in the left-right direction about the rotating shaft 42 (see FIGS. 11 and 12).

[0046] The blood collection tube support member 31 is disposed in the housing 11 via the connecting member 46 and the rotating shaft 42 so that the support groove portion 32 is located directly below the blood collection tube inlet 12 in a balanced state in the left-right direction. The position where the support groove portion 32 is directly below the blood collection tube inlet 12 is set as a reference position (see FIG. 10). Furthermore, the blood collection tube support member 31 is moved in an arc shape in the left-right direction around the rotating shaft 42 from the reference position, thereby being swung left-right. In this embodiment, the blood collection tube support member 31 is set to swung between swing positions (see FIG. 11) set to the left and right of the reference position. Here, the housing 11 is provided with a reference position sensor 65 (see FIG. 8) that detects the reference position, and swing position sensors 66, 67 (see FIG. 8) that detect the left and right swing positions, respectively. By controlling the drive of the stepping motor 43 in accordance with the detection of these sensors, the operation of stopping the blood collection tube support member 31 at the reference position and the operation of swinging the blood collection tube support member 31 between the left and right swing positions can be performed.

[0047] FIG. 11(A) shows a swing position on the right side of the reference position, and FIG. 11(B) shows a swing position on the left side of the reference position. These left and right swing positions are set so that the blood collection tube 81 is held within the left and right width of the blood collection tube inlet 12 while being supported on the support groove 32 of the blood collection tube support member 31. As a result, while the blood collection tube support member 31 is swinging between the left and right swing positions, the blood collection tube 81 supported on the support groove 32 is held in a state exposed upward through the blood collection tube inlet 12. That is, while swinging, the blood collection tube 81 can freely rotate in the left and right direction on the support groove 32 within the left and right width of the blood collection tube inlet 12. Here, the range in which the blood collection tube 81 is held within the left and right width of the blood collection tube inlet 12 while the blood collection tube support member 31 is stopped at the reference position and swinging is the detection position of the present invention. Regardless of whether the blood collection tube support member 31 is stopped or moving, the state in which the blood collection tube 81 is supported on the support groove portion 32 is the supporting state of the blood collection tube support member 31 according to the present invention. Therefore, in this embodiment, the blood collection tube support member 31 is in the supporting state at least between the left and right swing positions.

[0048] Furthermore, the blood collection tube support member 31 is moved about the rotation shaft 42 to a lowered position (see FIG. 12) that is higher than the rightward swing position. Here, the lowered position is a position where the blood collection tube 81 supported in the support groove 32 of the blood collection tube support member 31 is dropped below the blood collection tube support member 31, and is set to a position where the blood collection tube 81 in the support groove 32 can be dropped stably and reliably downward. Here, the housing 11 is provided with a lowered position sensor 68 (see FIG. 8) that detects this lowered position, and the stepping motor 43 is driven and controlled according to the detection of the lowered position sensor 68, thereby performing an operation of moving the blood collection tube support member 31 to the lowered position. In this embodiment, when the blood collection tube support member 31 is moved to the lowered position, the blood collection tube 81 supported by the support groove portion 32 abuts against the lower edge of the right-side guide plate 21a and cannot move any further to the right, so that the blood collection tube 81 tends to climb over the raised portion 33 on the left side of the blood collection tube support member 31 and fall downward.

[0049] 2 to 4 and 9 to 11, an optical code reader 25 capable of reading a barcode in a non-contact manner is disposed on the upper portion of the left guide plate 21b constituting the blood collection tube inlet 12. In this embodiment, the optical code reader 25 is disposed facing the blood collection tube inlet 12, and is capable of reading the barcode 86 of the blood collection tube 81 at the detection position by the blood collection tube support member 31 through the blood collection tube inlet 12. That is, when the blood collection tube support member 31 is between the left and right swing positions (see FIGS. 9 and 10), and the barcode 86 of the blood collection tube 81 supported on the support groove portion 32 of the blood collection tube support member 31 is at a position facing the optical code reader 25, the optical code reader 25 can read the barcode 86 of the blood collection tube 81. In other words, the detection position where the blood collection tube 81 is held between the left and right swinging positions is set as a position where the barcode 86 of the blood collection tube 81 is read by the optical code reading device 25 by making the barcode 86 of the blood collection tube 81 a circumferential position facing the optical code reading device 25.

[0050] In addition, at the lower end of the left-side guide plate 21b, as shown in Figures 9 to 11, a tube-in-tube detection sensor 26 (see Figure 8) is provided for detecting the blood collection tube 81 supported by the support groove portion 32 of the blood collection tube support member 31 in the reference position.

[0051] On the other hand, the table 15 is disposed below the blood collection tube support member 31 with a storage space for the tray 80 so that the tray 80 containing the blood collection tubes 81 can be disposed between the table 15 and the blood collection tube support member 31. When the tray 80 is placed on the table 15 (stored in the storage space), the blood collection tubes 81 dropped from the blood collection tube support member 31 in the lowered position are accommodated in the tray 80. Furthermore, the load cell device 16 (see FIG. 8) is disposed below the table 15. The load cell device 16 measures the weight on the table 15, and a conventionally known device can be applied, so that details thereof will be omitted. The tray 80 can also store a plurality of blood collection tubes 81, and a conventionally used device in medical institutions such as hospitals can be applied, so that details thereof will be omitted.

[0052] 2 to 4, the housing 11 is provided with a power switch 51, a reactivation button 52, a green lamp 53, a first red lamp 54, and a second red lamp 55 on the front side. The power switch 51 is for turning on / off the power of the blood collection confirmation device 5 and can be operated by the blood collection operator. The reactivation button 52 is for swinging the blood collection tube support member 31 by turning it on and can be operated by the blood collection operator. The green lamp 53 is turned on when the tray 80 is placed on the table 15 and the load cell device 16 is in a state where the weight can be measured, and notifies the user that the blood collection tube 81 can be inserted through the blood collection tube insertion port 12. The first red lamp 54 is turned on when there is an error in reading the barcode 86 of the blood collection tube 81 and an error in the operation of the blood collection tube support member 31, and notifies the user of these errors. The second red lamp 55 is turned on when the amount of blood collected in the blood collection tube 81 is insufficient, and notifies the user that the amount of blood collected is insufficient.

[0053] As shown in Fig. 8, the blood collection confirmation device 5 is provided with a control device 61 that controls the blood collection confirmation device 5. The control device 61 has a board composed of a CPU, ROM, RAM, etc. (not shown), and has a function of transmitting and receiving information such as data and signals to and from the blood collection management server 2. The control device 61 is connected to the optical code reader 25 and the load cell device 16 so as to be able to input and output data and signals, and is also connected to a power supply unit 63 equipped with the power switch 51. The power supply unit 63 supplies power supplied from an external power source to each device constituting the blood collection confirmation device 5, and is connected to each device by a power supply cord (not shown). The stepping motor 43, the reactivation button 52, the green lamp 53, the first red lamp 54, and the second red lamp 55 are also connected to the control device 61, and drives and controls them. Furthermore, the control device 61 is connected to the in-pipe detection sensor 26, the left swing position sensor 66, the right swing position sensor 67, the lowered position sensor 68, and the tray detection sensor 69 through a sensor board 62, and signals detected by each of these sensors are input through the sensor board 62. The tray detection sensor 69 is a sensor that detects a tray 80 placed on the table 15.

[0054] Next, a series of operations for confirming the amount of collected blood in the blood collection tube 81 by the blood collection management system 1 of this embodiment will be described. This series of operations is performed by a blood collection reading process executed by the blood collection confirmation device 5 and a blood collection evaluation process executed by the blood collection management server 2.

[0055] FIG. 13 shows the blood collection reading process executed by the blood collection confirmation device 5. When power is supplied by turning on the power switch 51, the initial operation of each of the devices is executed by the initial operation process (S100). Specifically, the initial operation of checking the zero balance is executed by the load cell device 16, and if it is normal, the signal is input to the control device 61. When the control device 61 inputs a normal signal, it turns on the green lamp 53 to notify that the tray 80 can be placed on the table 15. Furthermore, the control device 61 confirms that the blood collection tube support member 31 is in the reference position by the signal input from the reference position sensor (see FIG. 10). Here, if the blood collection tube support member 31 is not in the reference position, the control device 61 drives and controls the stepping motor 43 to move the blood collection tube support member 31 to the reference position and stop it. In this embodiment, the initial operation process is skipped except when the power switch 51 is turned on.

[0056] When the tray 80 is placed on the table 15 and the tray detection sensor 69 detects the tray 80, a read preparation process is executed (S105 to S110). In this read preparation process (S110), an operation of obtaining zero balance is executed in the load cell device 16 with the tray 80 placed thereon. Then, when the zero balance is stabilized, the control device 61, which has received the signal, turns on the green lamp 53 to notify that the preparation for reading the blood collection tube 81 is complete. Here, when the control device 61 receives the detection signal for the tray 80 from the tray detection sensor 69, it temporarily turns off the green lamp 53, and then turns it on when the zero balance is stabilized. On the other hand, when an error occurs, such as when the zero balance cannot be stabilized, the green lamp 53 is not turned on.

[0057] When the blood collection tube 81 is inserted from the blood collection tube insertion port 12, the in-tube detection sensor 26 detects the blood collection tube 81, and outputs a signal to the control device 61 (S115). In response to the input of this signal, the control device 61 executes a swing process (S120) and drives and controls the stepping motor 43 to swing the blood collection tube support member 31 between the left and right swing positions (see FIG. 11). Here, the control device 61 swings the blood collection tube support member 31 by rotating the stepping motor 43 in a forward and reverse direction every time it inputs a detection signal from the left and right swing position sensor. This swing causes the blood collection tube 81 to roll left and right on the support groove portion 32 of the blood collection tube support member 31, and rotates (fluctuates) in the circumferential direction in accordance with the rolling. Then, when the optical code reader 25 reads the barcode 86 of the blood collection tube 81 supported in the support groove portion 32 of the blood collection tube support member 31, it outputs a signal including the read identification information to the control device 61.

[0058] When a signal including the identification information is input from the optical code reader 25, a lowering operation process is executed (S125 to S130). This lowering operation process (S130) drives and controls the stepping motor 43 to move the blood collection tube support member 31 to the lowered position and temporarily stops it at the lowered position (see FIG. 12). When the signal is input from the optical code reader 25 in this manner, the rocking is stopped and the blood collection tube 81 supported by the blood collection tube support member 31 is moved to the lowered position. This causes the blood collection tube 81 supported by the blood collection tube support member 31 to fall into the tray 80 on the table 15. On the other hand, the control device 61 counts the number of left and right swings based on the signal input from the reference position sensor 65 and the left and right swing position sensors 66, 67, and when the number of swings reaches a predetermined number (e.g., 5 times) without receiving the signal from the optical code reader 25, it controls the driving of the stepping motor 43 to stop the blood collection tube support member 31 at the reference position (S150 to S155). In response to this, it turns on the first red lamp 54 to notify that the barcode 86 cannot be read. In this state, when the re-activation button 52 is operated (S160), the control device 61 turns off the first red lamp 54 and again controls the driving of the stepping motor 43 to swing the blood collection tube support member 31. In this embodiment, the rocking starts with moving the blood collection tube support member 31 from the reference position to the right (toward the lowered position). As a result, when the optical code reader 25 reads the barcode 86 of the blood collection tube 81 during the movement from the reference position to the rightward rocking position, the blood collection tube support member 31 passes through the rightward rocking position and is moved to the lowered position.

[0059] After the blood collection tube support member 31 moves to the lowered position, a weight detection process (S140) is executed when a weight information signal is input from the load cell device 16. Here, when the load cell device 16 detects a weight change due to the blood collection tube 81 entering the tray 80, the load cell device 16 detects the weight and outputs a signal of the detected weight information to the control device 61. In this embodiment, when the load cell device 16 detects a weight change, it measures the weight at a predetermined time interval (e.g., 0.2 second intervals) and outputs a signal of weight information to the control device 61 for each measurement.

[0060] In the weight detection process (S140), each time the signal is input from the load cell device 16, the weight information included in each signal is confirmed, and the weight is waited until the weight is stable (for example, within ±1 g). Then, when the weight is stabilized, a command to instruct the load cell device 16 to stop outputting the signal is output, and the stepping motor 43 is driven and controlled to move the blood collection tube support member 31 from the lowered position to the reference position and stop it. Furthermore, in this weight detection process, the weight of the collected blood in the blood collection tube 81 that has entered the tray 80 by the movement of the blood collection tube support member 31 to the lowered position is calculated from the stable weight information. That is, since the weight information input from the load cell device 16 is the weight of the blood collection tube 81 in the tray 80 after blood collection, the weight of the collected blood (weight of blood) in the blood collection tube 81 is calculated by subtracting the weight of only the blood collection tube 81 that is stored in advance. In this embodiment, since the load cell device 16 measures the weight change before and after the weight change, the weight information input from the load cell device 16 corresponds to the weight of one blood collection tube 81 from which blood was collected.

[0061] When the collected blood weight is acquired by the weight detection process, the control device 61 transmits the collected blood weight information and the blood collection tube acquisition information including the identification information input from the optical code reader 25 to the blood collection management server 2 (S170). Then, the control device 61 waits until it receives the blood collection evaluation information described below from the blood collection management server 2 (S175).

[0062] When the blood collection evaluation information is received from the blood collection management server 2, a blood collection evaluation notification process is executed (S180). In this blood collection evaluation notification process, the identification information collation result and blood collection amount judgment information (information indicating the judgment result of whether the blood collection amount is sufficient or not) are confirmed from the blood collection evaluation information. Then, when the identification information collation result indicates a positive judgment and the blood collection amount judgment information indicates the blood collection amount is sufficient, the green lamp 53 is turned on to notify that blood collection from the blood collection tube 81 has been performed correctly. On the other hand, when the identification information judgment result indicates a negative judgment, the first red lamp 54 is made to flash to notify that the information of the blood recipient is incorrect. Also, when the blood collection amount judgment information indicates an insufficient amount of blood, the second red lamp 55 is made to flash to notify that the blood collection amount is insufficient. The identification information collation result and blood collection amount judgment information will be described later in the blood collection evaluation process.

[0063] 14 shows the blood collection evaluation process executed by the blood collection management server 2. In this blood collection evaluation process, when the blood collection tube acquisition information is received from the blood collection confirmation device 5, the identification information and weight information included in the blood collection tube acquisition information are confirmed, and blood collection master information of the blood collection recipient registered in the database 3 is read according to the identification information (S200 to S205). Here, in the database 3, identification information of the blood collection recipient ordered by a doctor, nurse, etc. (name and ID of the blood collection recipient, etc.) and blood collection test information (information indicating the content of blood collection) are stored as blood collection master information for each blood collection recipient. Such identification information and blood collection test information are registered in a higher-level system (not shown) of the hospital in advance, and are acquired from the higher-level system by the blood collection management server 2 and stored in the database 3 as blood collection master information. The blood collection test information includes information on clinical tests performed by blood collection, information on the number of blood collection tubes 81 used in each clinical test, and information indicating the lower limit of the amount of blood to be collected in each blood collection tube 81. In this embodiment, the lower limit information on the amount of collected blood indicates the lower limit weight value of the amount of blood to be collected in each blood collection tube 81, and is set according to the contents of the clinical test and the subject to whom blood is to be collected. This lower limit weight value corresponds to the threshold weight value of the present invention.

[0064] When the blood collection master information is read from the database 3, an identification information determination process (S210) and a blood collection amount determination process (S215) are executed. In the identification information determination process, the identification information of the blood collection tube acquisition information is compared with the identification information of the blood collection master information to determine whether they match. In the blood collection amount determination process, it is determined whether the weight information of the blood collection tube acquisition information reaches the lower limit weight value (lower limit information on the amount of blood collection) included in the blood collection test information of the blood collection master information. Here, the determination of whether the weight information of the blood collection tube acquisition information reaches the lower limit weight value is, in other words, a determination of whether the amount of blood collected in the blood collection tube 81 is sufficient (reaches the lower limit amount) or insufficient (does not reach the lower limit amount). Therefore, a determination result that the weight information does not reach the lower limit weight value indicates an insufficient amount of blood collected in the blood collection tube 81.

[0065] Thereafter, a data storage process (S220) is executed, and if the identification information is matched by the identification information determination process and the weight information is determined to have reached the lower limit weight value by the blood collection volume determination process, information indicating that blood has been collected correctly is stored in the blood collection master information of the database 3.

[0066] Furthermore, an evaluation information sending process (S225) is executed, and blood collection evaluation information including the judgment result of the identification information judgment process (the identification information matching result) and the judgment result of the blood collection amount judgment process (judgment information of the blood collection amount) is sent to the blood collection confirmation device 5.

[0067] Next, a mode of use of the blood collection confirmation device 5 will be described. Before starting the blood collection operation, the blood collection operator turns on the power switch 51 of the blood collection confirmation device 5. After that, when it is confirmed that the green lamp 53 of the blood collection confirmation device 5 is lit, the blood collection operator inserts a tray 80 for accommodating blood collection tubes 81 for each blood recipient through the tray inlet / outlet 13 of the blood collection confirmation device 5 and places it on the table 15. After that, with the green lamp 53 lit, the blood collection operator inserts the blood collection tube 81 from which blood has been collected from the blood recipient through the blood collection tube inlet 12 of the blood collection confirmation device 5. Here, the blood collection tube 81 falls from the blood collection tube inlet 12 in a state of lying on its side in the front-rear direction, and is supported in the state of lying on its side within the support groove portion 32 of the blood collection tube support member 31 as shown in FIG. 10.

[0068] When the blood collection tube 81 supported by the blood collection tube support member 31 is detected by the in-tube detection sensor 26, the blood collection tube support member 31 swings left and right as shown in Fig. 11, and this swinging allows the blood collection tube 81 to rotate (fluctuate) in the circumferential direction by freely rotating left and right in the support groove portion 32 while being kept at the detection position. Then, the rotation of the blood collection tube 81 can move the barcode 86 of the label 85 affixed to the blood collection tube 81 to a circumferential position facing the optical code reader 25. This allows the optical code reader 25 to read the barcode 86 of the blood collection tube 81. Here, in the blood collection confirmation device 5 of the embodiment, the support groove portion 32 of the blood collection tube support member 31 has a structure for supporting the blood collection tube 81 rotatably in the circumferential direction, and the blood collection tube 81 is swung in the left-right direction perpendicular to the longitudinal direction, thereby rotating (changing) the blood collection tube 81 in the circumferential direction during the swinging. That is, the structure of the support groove portion 32 and the function of swinging the blood collection tube support member 31 cause the blood collection tube 81 to rotate in the circumferential direction, which is necessary for the optical code reader 25 to read the barcode 86 of the blood collection tube 81. The rotation of the blood collection tube 81 caused during the swinging includes not only turning the blood collection tube 81 in the circumferential direction more than once, but also turning the blood collection tube 81 less than once.

[0069] When the optical code reader 25 reads the barcode 86 of the blood collection tube 81 by the swinging of the blood collection tube support member 31, the blood collection tube support member 31 moves to the lowered position as shown in Fig. 12, and the blood collection tube 81 supported by the support groove portion 32 falls downward. As a result, when the blood collection tube 81 enters the tray 80 on the table 15, the weight of the blood collection tube 81 is measured. On the other hand, if the optical code reader 25 cannot read the barcode 86 of the blood collection tube 81 while the blood collection tube support member 31 is oscillating, the blood collection tube support member 31 stops at the reference position, and the first red lamp 54 turns on. When the blood collection worker confirms that the first red lamp 54 is oscillating, he or she takes out the blood collection tube 81, reinserts it, or performs other operations, and operates the reactivation button 52. This causes the blood collection tube support member 31 to oscillate again, and when the optical code reader 25 reads the barcode 86 of the blood collection tube 81, the blood collection tube support member 31 moves to the lowered position, and the blood collection tube 81 falls, in the same manner as described above.

[0070] When the load cell device 16 detects the weight of the blood collection tube 81 placed in the tray 80 as the blood collection tube support member 31 moves to the lowered position, information on the weight of the collected blood in the blood collection tube 81 and the identification information read by the optical code reader 25 are transmitted to the blood collection management server 2. After that, when the blood collection confirmation device 5 receives blood collection evaluation information from the blood collection management server 2, the green lamp 53, the first red lamp 54, or the second red wrap 55 is turned on according to the blood collection evaluation information. Here, when the green lamp 53 is turned on, it is understood that the blood collection tube 81 inserted into the blood collection confirmation device 5 has been properly collected, so the blood collection operator continues to perform blood collection work for the same blood collection subject, inserts the necessary number of blood collection tubes 81 into the blood collection confirmation device 5 in the same manner, and checks whether each blood collection tube 81 is normal or not. Then, when all the blood collection tubes 81 required for the blood collection subject are normal, the tray 80 is removed. On the other hand, when the first red lamp 54 or the second red lamp 55 is lit, the blood collection tube 81 is removed, and the label 85 of the blood collection tube 81 is checked and the missing blood is collected. This series of steps is carried out for each blood collection subject.

[0071] In this manner, according to the blood collection confirmation device 5 of the present embodiment, the blood collection tube support member 31 supporting the blood collection tube 81 is swung, whereby the barcode 86 of the label 85 affixed to the blood collection tube 81 can be read accurately and stably. After reading the identification information from the barcode 86, the blood collection tube 81 is moved to the load cell device 16 to measure the weight of the collected blood, whereby accurate information (the identification information and the collected blood weight information) related to the blood collection tube 81 obtained by the blood collection operation can be transmitted to the blood collection management server 2. Meanwhile, the blood collection management server 2 can accurately collate the identification information and determine whether the collected blood amount (collected blood weight) has reached the required lower limit amount based on the information received from the blood collection confirmation device 5, and transmit blood collection evaluation information indicating the result to the blood collection confirmation device 5. When the blood collection confirmation device 5 receives the blood collection evaluation information from the blood collection management server 2, the blood collection evaluation information is notified, and this notification enables the blood collection operator to easily and accurately know whether the identification information of the blood collection tube 81 inserted into the blood collection confirmation device 5 is correct and whether the amount of blood collected from the blood collection tube 81 is sufficient. In the blood collection management system 1 of this embodiment, by inserting the blood collection tube 81 into the blood collection confirmation device 5, the collation result of the identification information and the judgment information of the blood collection amount (whether the lower limit amount has been reached or not) can be accurately obtained in a relatively short time. Therefore, if the blood collection amount is insufficient, additional blood can be collected from the blood collection recipient immediately or blood can be collected again. In this way, according to the configuration of this embodiment, the blood collection evaluation information can be obtained during a series of blood collection operations from the start to the end of blood collection, so there is no need to call the blood collection recipient for re-collection after the blood collection operation is once completed as in the conventional method, and the time and burden required for the re-collection operation can be significantly reduced. Furthermore, the burden on the blood collection recipient for the re-collection operation performed due to the insufficient blood collection amount can be reduced, and troubles caused by the re-collection operation can also be suppressed.

[0072] Furthermore, the blood collection confirmation device 5 measures the weight of the blood collection tube 81 after blood collection using the load cell device 16, and obtains the weight of the collected blood in the blood collection tube 81 from this weight, so that the collected blood weight can be measured accurately and stably. Then, the blood collection management server 2 judges whether or not this collected blood weight reaches the previously set lower limit weight value. According to the configuration of this embodiment, it is possible to judge with high accuracy whether or not the amount of collected blood reaches the amount required for clinical testing, compared to the conventional visual inspection by the blood collection operator described above. Therefore, it is possible to prevent the occurrence of a situation in which a clinical test cannot be performed due to an insufficient amount of collected blood, and to prevent distrust in blood collection work and a deterioration in the image of medical institutions from occurring.

[0073] In this embodiment, blood collection evaluation information can be obtained by inserting a blood collection tube 81 into the blood collection tube insertion port 12 of the blood collection confirmation device 5, and therefore, as a blood collection work flow, it is essential to insert the blood collection tube 81 into the blood collection tube insertion port 12. Therefore, it is possible to suppress the occurrence of human error in which the blood collection tube 81 is mistakenly disposed of in a disposal box, and it is possible to reduce the effort and time required for a search work caused by the mistaken disposal in the disposal box, and also to reduce the risk of infection caused by touching the disposal box.

[0074] In the blood collection confirmation device 5 of this embodiment, the blood collection tube support member 31, which supports the blood collection tube 81 so that it can rotate in the circumferential direction, is swung left and right while supporting the blood collection tube 81, thereby allowing the blood collection tube 81 to rotate (fluctuate) in the circumferential direction while being kept at the detection position, and the barcode 86 of the blood collection tube 81 to be read by the optical code reader 25. Since the barcode 86 of the blood collection tube 81 supported by the blood collection tube support member 31 can be read by the relatively simple action of swiveling the blood collection tube support member 31 in this manner, the optical code reader 25 can accurately and stably read the barcode 86. Furthermore, when the optical code reader 25 cannot read the barcode 86 while the blood collection confirmation device 5 is rocking the blood collection tube support member 31, the blood collection confirmation device 5 stops the rocking and notifies the user that the barcode cannot be read, so that the user can know that the barcode cannot be read and can perform an operation such as reinserting the blood collection tube 81. This makes it possible to prevent a blood collection tube 81 whose barcode 86 cannot be read from being stored in the tray 80. Furthermore, the blood collection confirmation device 5 automatically executes a series of operations from detecting the blood collection tube 81 inserted through the blood collection tube insertion port 12 to storing the blood collection tube 81 in the tray 80 and measuring the weight of the collected blood, thereby reducing the burden on the blood collection operator required to obtain the blood collection evaluation result (whether the amount of collected blood is sufficient or not).

[0075] Furthermore, since the blood collection confirmation device 5 of this embodiment uses a blood collection tube 81 to which a label 85 having a barcode 86 printed thereon is affixed, it has the advantage of being able to reduce the cost required for the blood collection tube compared to, for example, a label having an RFID tag. EXAMPLES

[0076] The blood collection management system 1 of the second embodiment is configured such that the blood collection confirmation device 5 determines whether or not the weight of collected blood in the blood collection tube 81 has reached the lower limit weight value (lower limit information on the amount of collected blood) obtained from the blood collection management server 2.

[0077] In the blood collection confirmation device 5 of the second embodiment, when the optical code reader 25 reads the barcode 86 of the blood collection tube 81 inserted through the blood collection tube inlet 12, it transmits the identification information read from the barcode 86 to the blood collection management server 2. When the blood collection management server 2 receives the identification information from the blood collection confirmation device 5, it acquires the blood collection test information from the database 3 based on the identification information and transmits information for determination including the blood collection test information to the blood collection confirmation device 5. When the blood collection confirmation device 5 receives the information for determination from the blood collection management server 2, it determines whether the collected blood weight calculated from the weight measured by the load cell device 16 reaches the lower limit weight value included in the information for determination, and notifies the result of the determination by turning on or off the lamps 53 to 55.

[0078] In addition, in the configuration of Example 2, the blood collection management server 2 acquires information for determination (lower limit weight value) based on the identification information received from the blood collection confirmation device 5 and transmits the information for determination to the blood collection confirmation device 5, and the blood collection confirmation device 5 performs a process of determining the blood collection weight using the lower limit weight value of the information for determination received from the blood collection management server 2. Therefore, the same components are denoted with the same symbols, and descriptions of the same components and the same processing contents are omitted as appropriate.

[0079] In the second embodiment, a series of operations for confirming the amount of collected blood in the blood collection tube 81 is executed by a blood collection reading and determining process by the blood collection confirmation device 5 and an information acquisition and transmission process by the blood collection management server 2. The blood collection reading and determining process and the information acquisition and transmission process will be described below.

[0080] 15 shows the blood collection reading determination process executed by the blood collection confirmation device 5. Each process of S300 to S325 in the blood collection reading determination process is the same as each process of S100 to S125 in the blood collection reading process of the above-mentioned embodiment 1. Also, each process of S350 to S360 in the blood collection reading determination process is the same as each process of S150 to S160 in the blood collection reading process of the above-mentioned embodiment 1.

[0081] In the blood collection reading judgment process, when the control device 61 receives a signal including the identification information read from the barcode 86 of the blood collection tube 81 from the optical code reader 25 (positive judgment in S325), it executes the acquired information transmission process (S330). In this acquired information transmission process, the blood collection tube acquisition information including the identification information input from the optical code reader 25 is transmitted to the blood collection management server 2.

[0082] Furthermore, when the control device 61 receives the signal including the identification information, it executes a descent operation process (S340). This descent operation process is the same as the descent operation process (S130) of the first embodiment described above.

[0083] After the blood collection tube support member 31 is moved to the lowered position by the lowering operation process, a weight detection process (S370) is executed when a weight information signal is input from the load cell device 16. This weight detection process is the same as the weight detection process (S140) in the first embodiment described above.

[0084] When the control device 61 executes the weight detection process, it checks whether or not it has received the determination information described below from the blood collection management server 2 (S375), and if the determination information has been received, it executes the blood collection volume determination process (S380), whereas if the determination information has not been received, it waits until the determination information is received (S375).

[0085] In the blood collection amount determination process (S380), the identification information and the lower limit weight value included in the determination information received from the blood collection management server 2 are confirmed, and it is determined whether the collected blood weight in the blood collection tube 81 calculated by the weight detection process (S370) reaches the lower limit weight value. Here, the determination of whether the weight information of the blood collection tube acquisition information reaches the lower limit weight value is a determination of whether the amount of collected blood collected in the blood collection tube 81 is sufficient (reaches the lower limit amount) or insufficient (does not reach the lower limit amount), as in the above-mentioned Example 1. Therefore, the determination result that the weight information does not reach the lower limit weight value indicates an insufficient amount of collected blood in the blood collection tube 81. Furthermore, in the blood collection amount determination process of the second embodiment, when the weight of collected blood in the blood collection tube 81 reaches the lower limit weight value, information including the identification information and information indicating this determination result is transmitted to the blood collection management server 2. Upon receiving this information, the blood collection management server 2 performs a process of storing information indicating that blood has been collected correctly in the blood collection master information of the database 3 (not shown).

[0086] After the collected blood weight is determined by the collected blood volume determination process, a blood collection evaluation and notification process is executed (S390). In this blood collection evaluation and notification process, the result of the determination of the collected blood weight by the collected blood volume determination process (S380) and the result of the collation of the identification information included in the determination information are confirmed, and the lamps 53 to 55 are turned on or blinked depending on these results. Specifically, similar to the above-mentioned embodiment 1, when the collation result of the identification information indicates a positive determination and the determination information of the collected blood volume indicates that the collected blood volume is sufficient, the green lamp 53 is turned on, when the determination result of the identification information indicates a negative determination, the first red lamp 54 is blinked, and when the determination information of the collected blood volume indicates that the collected blood volume is insufficient, the second red lamp 55 is blinked.

[0087] 16 shows the information acquisition and transmission process executed by the blood collection management server 2. In this information acquisition and transmission process, when the blood collection tube acquisition information is received from the blood collection confirmation device 5, the identification information included in the blood collection tube acquisition information is confirmed, and blood collection master information of the blood collection recipient registered in the database 3 is read according to the identification information (S400 to S405). Here, in the database 3, similar to the above-mentioned embodiment 1, identification information of the blood collection recipient ordered by a doctor, nurse, etc. and blood collection test information are stored as blood collection master information for each blood collection recipient. The blood collection test information includes information on the clinical test performed by blood collection, information on the number of blood collection tubes 81 used in each clinical test, and information indicating the lower limit of the amount of blood to be collected in each blood collection tube 81 (the above-mentioned lower limit weight value).

[0088] An identification information determination process (S410) is executed when the blood collection master information is read from the database 3. This identification information determination process is the same as the identification information determination process (S210) in the first embodiment described above.

[0089] After this, a process for transmitting information for determination (S420) is executed, and information for determination, which includes the determination result by the identification information determination process (the result of matching the identification information) and the blood collection test information (the lower limit weight value of the blood collection amount) of the blood collection master information, is transmitted to the blood collection confirmation device 5.

[0090] In the blood collection management system 1 of Example 2, the usage mode of the blood collection confirmation device 5 is the same as that of the above-mentioned Example 1. Therefore, the blood collection confirmation device 5 of Example 2 can also achieve the same effects as those of the above-mentioned Example 1. And, the blood collection management system of Example 2 can also achieve the same effects as those of the above-mentioned Example 1. EXAMPLES

[0091] The blood collection management system 1 of Example 3 is configured so that the blood collection confirmation device 5 determines whether or not the weight of collected blood in the blood collection tube 81 has reached the lower limit weight value (lower limit information on the amount of collected blood), and the lower limit weight value is transmitted from the blood collection management server 2 to the blood collection confirmation device 5 based on identification information acquired by a specified blood collection operation preparation device (not shown) immediately before the blood collection operation.

[0092] A blood collection room is provided with a blood collection work preparation device (not shown) for reading the identification information of the blood collection recipient from the label 85 of the blood collection tube 81 and for reading the identification information of the blood collection worker from the name tag or the like of the blood collection worker immediately before blood collection. This blood collection work preparation device is communicably connected to the blood collection management server 2 via a communication cable. This blood collection work preparation device includes an optical code reader capable of reading the barcode 86 printed on the label 85 of the blood collection tube 81, and an information transmission device for transmitting the identification information read by the optical code reader to the blood collection management server 2. Here, a barcode storing the identification information of the blood collection worker is printed on the name tag of the blood collection worker, and the optical code reader of the blood collection work preparation device can read the identification information of the blood collection worker from the name tag of the blood collection worker. Then, the blood collection operation preparation device transmits blood collection implementation information, including the identification information of the blood recipient read from the blood collection tube 81 and the identification information of the blood collection operator read from the name tag of the blood collection operator, to the blood collection management server 2 by the information transmission device. Note that since a conventionally known configuration can be applied to such a blood collection operation preparation device, details will be omitted.

[0093] In the blood collection management server 2 of the third embodiment, when the blood collection execution information transmitted from the blood collection operation preparation device is received immediately before the blood collection operation, the blood collection confirmation device 5 obtains the blood collection test information from the database 3 based on the identification information of the blood collection execution information and transmits information for determination including the blood collection test information. When the blood collection confirmation device 5 receives information for determination from the blood collection management server 2, the blood collection confirmation device 5 obtains and stores the identification information and the lower limit weight value (information on the lower limit amount of blood collection) contained in the information for determination. Here, since the blood collection management server 2 transmits the information for determination to the blood collection confirmation device 5 based on the identification information (blood collection execution information) read by the blood collection operation preparation device immediately before the blood collection operation, the blood collection confirmation device 5 can usually receive the information for determination before the blood collection tube 81 is inserted. Furthermore, when the blood collection confirmation device 5 measures the weight of the blood collection tube 81 using the load cell device 16, it determines whether the calculated blood collection weight reaches the lower limit weight value of the determination information received from the blood collection management server 2, and notifies the result of the determination by turning on or off the lamps 53 to 55.

[0094] In addition, in the configuration of Example 3, the blood collection management server 2 acquires information for judgment (lower limit weight value) based on the blood collection execution information received from the blood collection work preparation device and transmits the information for judgment to the blood collection confirmation device 5, and the blood collection confirmation device 5 judges the blood collection weight using the lower limit weight value of the information for judgment received from the blood collection management server 2. Other than this, the configuration of Example 3 is the same as that of Examples 1 and 2 described above. Therefore, the same components are denoted by the same symbols, and descriptions of the same components and the same processing contents are omitted as appropriate.

[0095] In the third embodiment, a series of operations for confirming the amount of collected blood in the blood collection tube 81 is executed by a blood collection reading and determining process by the blood collection confirmation device 5 and an information acquisition and transmission process by the blood collection management server 2. The blood collection reading and determining process and the information acquisition and transmission process will be described below. The blood collection confirmation device 5 is configured to receive the blood collection execution information transmitted from the blood collection operation preparation device and acquire identification information and a lower limit weight value from the blood collection execution information. Since general processing for receiving information can be applied to the processing for receiving the blood collection execution information, details thereof will be omitted.

[0096] 17 shows the blood collection reading and determination process executed by the blood collection confirmation device 5. Each process of S500 to S560 in the blood collection reading and determination process is the same as each process of S100 to S160 in the blood collection reading process of the first embodiment described above.

[0097] The control device 61 executes a blood collection amount determination process (S570) following the S540 (weight detection process). In this blood collection amount determination process (S570), the identification information included in the determination information received from the blood collection management server 2 is confirmed, and the identification information is compared with the identification information input from the optical code reader 25 to determine whether they match. If the identification information is determined to match, the lower limit weight value included in the determination information is confirmed, and it is determined whether the blood weight in the blood collection tube 81 calculated by the weight detection process (S540) has reached the lower limit weight value. Such a determination and the result obtained by the determination are the same as those in the first and second embodiments described above. Furthermore, in the blood collection amount determination process of the third embodiment, similarly to the blood collection amount determination process of the second embodiment described above, when the weight of collected blood in the blood collection tube 81 reaches the lower limit weight value, information including the identification information and information indicating this determination result is transmitted to the blood collection management server 2. Upon receiving this information, the blood collection management server 2 performs a process of storing information indicating that blood has been collected correctly in the blood collection master information of the database 3 (not shown).

[0098] After the collected blood weight is determined by the collected blood volume determination process, a blood collection evaluation and notification process is executed (S580). In this blood collection evaluation and notification process, the result of the determination of the collected blood weight by the collected blood volume determination process (S570) and the result of the comparison of the identification information are confirmed, and the lamps 53 to 55 are turned on or blinked depending on these results. Specifically, similar to the above-mentioned first and second embodiments, when the result of the comparison of the identification information indicates a positive determination and the determination information of the collected blood volume indicates that the collected blood volume is sufficient, the green lamp 53 is turned on, when the determination result of the identification information indicates a negative determination, the first red lamp 54 is blinked, and when the determination information of the collected blood volume indicates that the collected blood volume is insufficient, the second red lamp 55 is blinked.

[0099] 18 shows the information acquisition and transmission process executed by the blood collection management server 2. In this information acquisition and transmission process, when the blood collection execution information is received from the blood collection operation preparation device (not shown), the identification information included in the blood collection execution information is confirmed, and blood collection master information of the blood collection recipient registered in the database 3 is read according to the identification information (S600 to S605). Here, in the database 3, similar to the above-mentioned first and second embodiments, identification information of the blood collection recipient ordered by a doctor, a nurse, etc. and blood collection test information are stored as blood collection master information for each blood collection recipient. The blood collection test information includes information on the clinical test to be performed by blood collection, information on the number of blood collection tubes 81 used in each clinical test, and information indicating the lower limit of the amount of blood to be collected in each blood collection tube 81 (the above-mentioned lower limit weight value).

[0100] After reading the blood collection master information from the database 3, a master information update process (S610) is executed. In this master information update process, the blood collection master information in the database 3 is updated by adding the identification information of the blood collection operator included in the blood collection execution information received from the blood collection work preparation device to the blood collection master information read from the database 3.

[0101] Thereafter, a process for transmitting information for determination (S620) is executed, and information for determination including the identification information of the blood recipient and blood collection test information (lower limit weight value of the blood collection amount) of the blood collection master information acquired in S605 is transmitted to the blood collection confirmation device 5.

[0102] In the blood collection management system 1 of Example 3, the usage of the blood collection confirmation device 5 is similar to that of the above-mentioned Examples 1 and 2. Therefore, the blood collection confirmation device 5 of Example 3 can also achieve the same effects as those of the above-mentioned Examples 1 and 2. And, the blood collection management system of Example 3 can also achieve the same effects as those of the above-mentioned Examples 1 and 2.

[0103] In the above-mentioned first to third embodiments, the bar code 86 on the label 85 of the blood collection tube 81 corresponds to the information storage means according to the present invention.

[0104] The present invention is not limited to the above-described embodiments, and configurations other than those of the above-described embodiments 1 to 3 can be implemented with appropriate modifications within the scope of the present invention. For example, in the first to third embodiments, the control device 61 is provided in the blood collection confirmation device 5, but the present invention is not limited to this, and the control device may be separate from the blood collection confirmation device 5 and connected via a cable that transmits information (data and signals). Here, the separate control device may be one that is dedicated to controlling the blood collection confirmation device 5, or may be one that can also control other devices.

[0105] In the first to third embodiments, the blood collection confirmation device 5 is configured to swing the blood collection tube support member 31 (including the rotating shaft 42 and the connecting member 46) by the drive device 41 (the stepping motor 43 and the belt mechanism 44), but the swinging mechanism can be modified as appropriate. For example, a mechanism that moves the blood collection tube support member 31 back and forth in the left and right direction can be used. In addition, in Examples 1 to 3, the blood collection tube 81 is dropped onto the tray 80 by moving the blood collection tube support member 31 to the lowered position, but this is not limited thereto. For example, a blood collection tube support member divided into left and right parts may be used, and the blood collection tube 81 may be dropped by separating the blood collection tube support member from the left and right parts.

[0106] In the first to third embodiments, the blood collection tube 81 is rotated (moved) in the circumferential direction by swinging the blood collection tube support member 31, but the present invention is not limited to this, and the mechanism for moving the blood collection tube 81 in the circumferential direction can be appropriately changed. For example, a configuration can be applied in which a roller is provided in contact with the outer surface of the blood collection tube 81, and the blood collection tube 81 is rotated in the circumferential direction by the rotation of the roller.

[0107] In the first embodiment, the control device 61 of the blood collection confirmation device 5 calculates the collected blood weight of only the blood in the blood collection tube 81 from the weight measured by the load cell device 16 (the weight of the blood collection tube 81 after blood collection) and transmits it to the blood collection management server 2, but the present invention is not limited to this. For example, the control device 61 may directly transmit the weight measured by the load cell device 16 (the weight of the blood collection tube 81 after blood collection). In this configuration, the blood collection management server 2 has a function of calculating the collected blood weight from the weight information received from the blood collection confirmation device 5 using the weight data of only the blood collection tube 81 stored in advance in the database 3. Alternatively, the database 3 may be configured to set a value obtained by adding the weight of the blood collection tube 81 and a lower limit weight value of the collected blood amount as a threshold weight value. Also, the load cell device 16 may be configured to measure the weight of collected blood in the blood collection tube 81, and the control device 61 may be configured to transmit information on the collected blood weight measured by the load cell device 16 to the blood collection management server 2. In this configuration, a function is required to control the load cell device 16 so that the collected blood weight can be measured directly. For example, after the collected blood weight is measured, control to achieve zero balance is executed.

[0108] Similarly, in Examples 2 and 3, the database 3 may be configured to set a threshold weight value that is the sum of the weight of the blood collection tube 81 and the lower limit weight value of the blood collection amount, and the control device 61 of the blood collection confirmation device 5 may determine the weight measured by the load cell device 16 (the weight of the blood collection tube 81 after blood collection) based on the threshold weight value received from the blood collection management server 2. In addition, in Examples 2 and 3, the load cell device 16 may be configured to measure the weight of the collected blood in the blood collection tube 81, and the control device 61 may be configured to determine whether the collected blood weight measured by the load cell device 16 has reached a lower limit weight value received from the blood collection management server 2.

[0109] In the first embodiment, the blood collection evaluation information is notified by turning on the green lamp 53, the first red lamp 54, or the second red lamp 55 in response to the blood collection evaluation information received from the blood collection management server 2, but the number of lamps and the type of lamps can be changed as appropriate. For example, one or more lamps capable of performing different light emission modes (light emission color, blinking, etc.) may be provided, and the blood collection evaluation information may be notified in response to the light emission mode of the lamp. Also, the blood collection evaluation information may be notified by a notification means other than the lamp. For example, the blood collection evaluation information may be notified by a monitor that displays the blood collection evaluation information, a speaker that generates the blood collection evaluation information by voice, or a printer that prints the blood collection evaluation information. Similarly, in the second and third embodiments, the number of lamps and the type of lamps can be changed as appropriate, and blood collection evaluation information can be notified by a notification means other than the lamps.

[0110] In the first to third embodiments, the blood collection confirmation device 5 is configured to target the blood collection tube 81 on which a label on which a barcode 86 is printed is affixed, but the present invention is not limited thereto, and may be configured to target a blood collection tube on which a label on which a two-dimensional code such as a QR code (registered trademark) is printed is affixed. This configuration can be realized by providing an optical code reader capable of reading the two-dimensional code. It is also possible to configure the blood collection tube to target a label on which an RFID tag is affixed. The blood collection confirmation device of this configuration includes a reader capable of reading information from an RFID tag, but does not require a function to swing the blood collection tube support member (it does require a function to move the blood collection tube support member from the reference position to the lowered position). In any of these configurations, the identification information stored in the two-dimensional coat or RFID tag can be read, and therefore the same effects as those of the above-mentioned embodiments can be achieved.

[0111] In the third embodiment, the blood collection management server 2 transmits information for determination (lower limit weight value of collected blood volume) to the blood collection confirmation device 5 based on the identification information of the blood collection tube 81 transmitted from the blood collection operation preparation device immediately before the blood collection operation, but the present invention is not limited to this. For example, when the identification information of the person to be collected is acquired at the reception desk of a hospital or a medical examination institution, the identification information is transmitted from a device installed at the reception desk to the blood collection management server 2, and the blood collection management server 2 transmits information for determination to the blood collection confirmation device 5. Alternatively, when blood collection is reserved, the blood collection management server 2 may automatically transmit information for determination at a predetermined timing before the blood collection operation (for example, before the start time of the blood collection operation on the reserved day) based on the reservation date and time.

[0112] In the first to third embodiments, the operation suitable for outpatient blood collection has been described, but the present invention is not limited thereto and can also be used for inpatient blood collection. For example, in inpatient blood collection, blood is generally collected in each hospital room and the blood collection tube is transported to a central laboratory, so the blood collection confirmation device 5 of the present embodiment is installed at the reception desk of the central laboratory. Then, the identification information and blood collection volume of the blood collection tube transported from each hospital room are confirmed at the reception desk of the central laboratory using the blood collection confirmation device 5 (blood collection management system 1). When the configuration of the third embodiment is applied to inpatient blood collection, the blood collection operator can read the identification information from the blood collection tube 81 using a portable blood collection work preparation device. In this way, the configurations of Examples 1 to 3 can be adapted for blood collection during hospitalization, and it is possible to accurately and easily know whether the amount of collected blood is sufficient before clinical testing.
