[0046] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the present invention will be further described below in conjunction with the embodiments and drawings.

[0047] In the description of the present invention, "several" means an indefinite quantity, "multiple" means more than two, "greater than", "less than", "exceed", etc. are understood to exclude the number itself, and "above", "below", "within", etc. are understood to include the number itself. If there is a description of "first" or "second", it is only used for the purpose of distinguishing technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0048] In the description of the present invention, the terms "comprises," "comprising" or any other variations thereof are intended to cover a non-exclusive inclusion, and may include other elements not explicitly listed in addition to those listed elements.

[0049] Blood must be stored with identification labels and quick-frozen. Quick-freezing is a key processing step for preserving coagulation factor VIII. The freezing rate and the core temperature of the blood are two key parameters. Special quick-freezing equipment should be used, and the blood bags to be quick-frozen should be placed flat one by one instead of overlapping and stacking. Fresh frozen blood and cold precipitated coagulation factors should be quickly frozen, and the central temperature of the blood should preferably be reduced to below -30°C within 60 minutes. In order to ensure that the effective components of the blood are not destroyed, the blood bags are required to be evenly placed on the flat plate of the freezer before freezing. In the related art, the blood quick-freezing machine currently used adopts a box with a door, a refrigerator is provided at the lower end of the box, and a refrigeration plate is provided on the box wall provided at the upper part of the box. The refrigerator conducts cooling to the refrigeration plate through a fan or a duct, and a refrigeration plate and a frame clamp for hanging blood clamps are provided at the upper end of the box to quickly freeze the blood. The shortcomings of this blood freezer are: first, the blood bag cannot be compressed, the freezing amount is small, the quick-frozen blood is not suitable for preservation, and the work efficiency is low; second, the production cost is high, the freezing speed is slow, and the blood preservation effect is poor; third, the blood quick-freezing machine generally adopts a manual method for placement, which has the disadvantages of being very inconvenient to operate, high labor intensity, easy damage to the identification label, and poor quick-freezing blood effect.

[0050] Based on this, an embodiment of the present invention provides a blood quick-freezing system and method, which automatically delivers the blood to be quick-frozen into the quick-freezing machine. The transportation of the quick-frozen blood and the operation of the quick-freezing machine can be completed automatically without manual supervision, thereby reducing the labor intensity of the operators and improving the degree of automation of the blood transportation and quick-freezing process.

[0051] According to a first aspect of the present invention, a blood quick freezing system is provided.

[0052] like Figure 1 As shown, in one embodiment, the blood quick-freezing system includes a plurality of quick-freezing machines 10 , a plurality of transport devices 20 and a host computer 30 .

[0053] The quick freezer 10 is used for quick freezing of blood.

[0054] The quick freezer 10 is centrally arranged in the quick freezing area. The quick freezer 10 is equipped with a cold stage for quick freezing of blood. The cold stage is composed of an upper cold plate and a lower cold plate. The opening and closing of the cold stage is achieved by fixing the upper cold plate and moving the lower cold plate vertically up and down, so that the lower cold plate and the upper cold plate clamp the blood bag and freeze it quickly in a direct surface contact conduction mode, so that the blood is quickly frozen in a short time, which minimizes the impact of long freezing time on blood quality. The lower cold plate moves downward to form a space for placing and taking out the blood bag with the upper cold plate, and the lower cold plate moves upward to press the blood bag together with the upper cold plate to achieve direct surface contact and quick freezing of blood.

[0055] The transport device 20 communicates with the quick freezer 10 and is used to place the blood into the quick freezer 10 .

[0056] The idle transport equipment 20 is centrally arranged in the equipment charging area or is returning to the equipment charging area after completing the blood transport task. The transport equipment 20 receives the control instruction of the host computer 30 and performs the automatic navigation and blood placement into the quick freezer 10. When performing the automatic navigation action, the idle transport equipment 20 receives the control instruction of the host computer 30 and starts to move toward the target from its current position. The transport equipment 20 senses the change of its position state in real time and reports it to the host computer 30. The host computer 30 receives the information reported by the transport equipment 20 and analyzes and processes it in time to determine whether the control instruction sent to the transport equipment 20 needs to be updated. If necessary, the control instruction sent to the transport equipment 20 is updated to adjust the route of the transport equipment 20. When the action of placing blood into the quick-freezer 10 is executed, the transport equipment 20 loaded with blood receives the control instruction of the upper computer 30 and sends the loaded blood into the cold table range of the corresponding quick-freezer 10. The upper computer 30 senses the status information of the transport equipment 20 and the quick-freezer 10 in real time, and determines whether it is necessary to update the control instruction sent to the transport equipment 20. If necessary, the control instruction sent to the transport equipment 20 and / or the quick-freezer 10 is updated to adjust the status of the transport equipment 20 and / or the quick-freezer 10.

[0057] The host computer 30 communicates with the quick freezer 10 and the transport device 20 respectively, and is used to receive the call request of the calling terminal and the status information of each quick freezer 10, generate the first path and the second path, control the idle transport device 20 to move along the first path, control the transport device 20 loaded with blood to move along the second path and put the loaded blood into the idle quick freezer 10, control the quick freezer 10 to freeze the blood, and update the status information of the freezer. Among them, the first path is the route from the current position of the transport device 20 to the calling terminal, and the second path is the route from the calling terminal to the idle quick freezer 10.

[0058] It should be noted that the call terminal is set in the component separation area, and the operator works in the component separation area to separate the blood in the blood bag. After the component separation is completed, the blood needs to be quickly frozen and stored. The operator sends a call request through the call terminal, thereby calling the transportation equipment 20 to transport the blood to be quickly frozen to the idle quick freezing machine 10 for quick freezing. Exemplarily, when the call terminal button in the component separation area is lit, it means that the transportation equipment 20 is idle. After the operator presses the call button of the call terminal, the call terminal sends a call request to call the transportation equipment 20.

[0059] The host computer 30 receives and processes the call request from the calling terminal, arranges the nearest idle transport equipment 20 to respond to the call request according to a preset algorithm, generates a first path and a second path to plan the route of the transport equipment 20, and issues a transport task to the transport equipment 20. On this basis, the host computer 30 informs the calling terminal that the call request of the calling terminal has been processed. The host computer 30 controls the transport equipment 20 to arrive at the location of the calling terminal according to the first path and waits for the operator to place the blood to be frozen on the transport equipment 20. The operator can send a transport request to the host computer 30 through the calling terminal. When the host computer 30 receives the transport request, it controls the transport equipment 20 loaded with blood to travel from the location of the calling terminal to the idle quick freezer 10 according to the second path. After the transport equipment 20 arrives at the quick freezer 10, the host computer 30 interacts with the quick freezer 10 through data. The transport equipment 20 and the quick freezer 10 cooperate with each other under the coordination of the host computer 30, thereby automatically sending the blood to be frozen into the quick freezer 10.

[0060] Therefore, by controlling the transport equipment 20 to transport the blood from the component separation area to the quick freezing area and automatically navigate to the corresponding quick freezing machine 10, the host computer 30 realizes data interaction between the transport equipment 20 and the quick freezing machine 10, and the transport equipment 20 interacts with the quick freezing machine 10 through the host computer 30. The transport equipment 20 and the quick freezing machine 10 cooperate with each other under the coordination of the host computer 30, so as to automatically send the blood to be quick-frozen into the quick freezing machine 10. The transportation of quick-frozen blood and the operation of the quick freezing machine 10 can be completed automatically without manual supervision, thereby reducing the labor intensity of the operators and improving the degree of automation of the blood transportation and quick freezing processes.

[0061] In some embodiments, the host computer 30 is further used to generate a third path, control the idle transport device 20 to travel to the quick-freezing machine 10 that has completed the quick-freezing process according to the third path, remove the blood in the quick-freezing machine 10 that has completed the quick-freezing process, and update the status information of the quick-freezing machine 10 that has completed the quick-freezing process to idle. The third path is the route from the current position of the transport device 20 to the quick-freezing machine 10 that has completed the quick-freezing process.

[0062] The host computer 30 receives the status information of each quick freezer 10. When the quick freezer 10 completes the quick freezing process of the blood, the host computer 30 calls the transport device 20 to take away the blood that has completed the quick freezing process in the quick freezer 10. The host computer 30 controls the transport device 20 to come to the location of the quick freezer 10 that has completed the quick freezing process according to the third path. The transport device 20 exchanges data with the quick freezer 10 through the host computer 30. The transport device 20 and the quick freezer 10 cooperate with each other under the coordination of the host computer 30 to take out the blood from the cold table of the quick freezer 10.

[0063] like Figure 1 and Figure 2As shown, in one embodiment, the transport device 20 includes a device body 21 , a drive assembly 23 and a slide assembly 24 .

[0064] The equipment body 21 is provided with a loading platform 22, which can be raised and lowered; a driving component 23 is provided on the loading platform 22; a sliding component 24 is provided on the loading platform 22, and the sliding component 24 cooperates with the driving component 23 in transmission, and can be driven by the driving component 23 and reciprocate in the horizontal direction.

[0065] The loading platform 22 is arranged in the horizontal direction and can be raised and lowered in the vertical direction. During the lifting and lowering process of the loading platform 22, the driving component 23 cooperates with the sliding component 24 to drive the sliding component 24 to reciprocate in the horizontal direction. Specifically, when the operator places the blood on the transport device 20, an external tray is placed on the surface of the loading platform 22, and multiple bags of blood can be stacked on the tray. The equipment body 21 drives the tray to move to the vicinity of the quick-freezer 10, and then the loading platform 22 rises or falls in the vertical direction to a horizontal height equivalent to the cold table of the quick-freezer 10, and the driving component 23 drives the sliding component 24 to move in the horizontal direction and approach the cold table of the quick-freezer 10. Since the sliding component 24 is located on the loading platform 22, the sliding component 24 can push the tray forward into the quick-freezer 10 when it moves in the horizontal direction and approaches the cold table of the quick-freezer 10. This process limits the movement range of the tray by the driving component 23 and the sliding component 24, so that the tray can be stably pushed into the quick-freezer 10. This process does not require manual assistance and is relatively safe.

[0066] In this embodiment, there are two slide assemblies 24, which are arranged at intervals. The driving assembly 23 is connected to a connecting frame, and the driving assembly 23 drives the connecting frame to reciprocate in the horizontal direction on the loading platform 22. Since multiple bags of blood are placed on the tray, two slide assemblies 24 are provided, and the two slide assemblies 24 simultaneously push the tray to move in the front-rear direction, which can evenly disperse the thrust on the tray and reduce the situation where the tray deviates from the target path during the sliding process.

[0067] In some embodiments, the transport device 20 is equipped with an ultrasonic detection device, a metal detection device, and a Hall detection device.

[0068] The ultrasonic detection device is used to detect the distance between the transport equipment 20 and external obstacles. The transport equipment 20 detects the distance between itself and external obstacles (including the quick freezer 10, other transport equipment 20, and other external obstacles) during the movement through the ultrasonic detection device, so as to intelligently adjust its posture and approach speed when approaching the quick freezer 10.

[0069] The metal detector is used to detect the distance between the transport device 20 and the quick freezer 10. The transport device 20 detects its close proximity to the quick freezer 10 through the metal detector, adjusts its own posture to face the quick freezer 10, and then approaches the quick freezer 10 after adjustment. During the process of the transport device 20 approaching the quick freezer 10, the metal detector dynamically detects its close proximity to the quick freezer 10 and dynamically adjusts its own posture.

[0070] The Hall detection device is used to detect the distance between the loading platform 22 and the cold table of the quick freezer 10. The transport device 20 adjusts the horizontal height of the loading platform 22. When the distance between the horizontal height of the loading platform 22 and the cold table of the quick freezer 10 is less than the preset distance, the transport device 20 detects the distance between the loading platform 22 and the cold table of the quick freezer 10 through the Hall magnetic detection device, fine-tunes the posture of the loading platform 22, and further aligns the loading platform 22 with the cold table of the quick freezer 10, so as to achieve precise alignment of the quick freezer 10.

[0071] In some embodiments, the transport device 20 wirelessly communicates with the corresponding quick freezer 10 through the host computer 30 to control the quick freezer 10 to open or close the cold stage.

[0072] When the action of putting the blood into the quick-freezing machine 10 is executed, the transport equipment 20 exchanges data with the quick-freezing machine 10 through the upper computer 30, and the transport equipment 20 sends a request to turn on the cold table to the quick-freezing machine 10 through the upper computer 30. After receiving the request, the quick-freezing machine 10 turns on the cold table, and the upper computer 30 feeds back the quick-freezing machine 10's cold table turning-on value to the transport equipment 20. The transport equipment 20 pushes the blood on the loading platform 22 into the cold table. Subsequently, the transport equipment 20 sends a request to turn off the cold table to the quick-freezing machine 10 through the upper computer 30. After receiving the request, the quick-freezing machine 10 turns off the cold table and starts to quick-freeze the blood in the cold table.

[0073] When taking out blood from the quick freezer 10, the transport device 20 goes to the quick freezer 10 that has completed the quick freezing process, and the transport device 20 sends a request to turn on the cold stage to the quick freezer 10 through the upper computer 30. The quick freezer 10 turns on the cold stage after receiving the request, and the upper computer 30 feeds back the value of turning on the cold stage of the quick freezer 10 to the transport device 20. The transport device 20 takes out blood from the quick freezer 10, and then the transport device 20 sends a request to turn off the cold stage to the quick freezer 10 through the upper computer 30. The quick freezer 10 turns off the cold stage after receiving the request, and the transport device 20 transports the quick-frozen blood to the designated location.

[0074] In some embodiments, the transport device 20 is equipped with an identification device for identifying blood information and personal identification information.

[0075] Specifically, the transport device 20 reads the blood information in the tray through the identification device, reads the operator's badge barcode, and the blood information of the blood station that does not use RFID. The blood information includes product name, blood volume, blood type, and blood donation code. The identification device can be equipped with an 8-channel RFID far-field large-area reading antenna, combined with 2 groups of 4-channel RFID driver modules, which can read the blood information in the entire tray at one time.

[0076] According to a second aspect of the present invention, a method for quick freezing of blood is provided.

[0077] The blood quick freezing method is applied to the blood quick freezing system, such as Figure 1 As shown, in one embodiment of the present invention, the blood quick-freezing system includes a plurality of quick-freezing machines 10, a plurality of transport devices 20 and a host computer 30, the transport devices 20 communicate with the quick-freezing machines 10, and the host computer 30 communicates with the quick-freezing machines 10 and the transport devices 20 respectively.

[0078] Figure 3 is a flow chart of a blood quick freezing method according to a first embodiment of the present invention, Figure 3 The method may include but is not limited to steps S301 to S302.

[0079] Step S301, receiving a call request from a calling terminal and status information of each quick-freezing machine.

[0080] Step S302: Generate a first path and a second path.

[0081] Among them, the first path is the route from the current position of the transportation equipment to the calling terminal, and the second path is the route from the calling terminal to the idle quick freezer.

[0082] Step S303: Control the idle transport equipment to move along the first path.

[0083] Step S304, controlling the transport device loaded with blood to move along the second path, and controlling the transport device loaded with blood to put the loaded blood into an idle quick freezer.

[0084] Step S305, controlling the quick-freezing machine to quick-freeze the blood and updating the state information of the quick-freezing machine.

[0085] Specifically, the host computer receives and processes the call request from the calling terminal, arranges the nearest idle transport equipment to respond to the call request according to a preset algorithm, generates a first path and a second path to plan the route of the transport equipment, and issues a transport task to the transport equipment. On this basis, the host computer informs the calling terminal that the call request from the calling terminal has been processed. The host computer controls the transport equipment to come to the location of the calling terminal according to the first path and waits for the operator to place the blood to be frozen on the transport equipment. The operator can send a transport request to the host computer through the calling terminal. When the host computer receives the transport request, it controls the transport equipment loaded with blood to travel from the location of the calling terminal to an idle quick freezer according to the second path. After the transport equipment arrives at the quick freezer, the host computer interacts with the quick freezer through data. The transport equipment and the quick freezer cooperate with each other under the coordination of the host computer, thereby automatically sending the blood to be frozen into the quick freezer.

[0086] Figure 4 is a flow chart of a blood quick freezing method according to a second embodiment of the present invention, wherein Figure 3 Based on the examples, Figure 4 The method may include but is not limited to steps S401 to S403.

[0087] Step S401: Generate a third path.

[0088] Among them, the third path is the route from the current position of the transportation equipment to the quick-freezing machine that completes the quick-freezing process.

[0089] Step S402, controlling the idle transport equipment to move to the quick-freezing machine that has completed the quick-freezing process according to the third path and taking out the blood in the quick-freezing machine that has completed the quick-freezing process;

[0090] Step S403, updating the status information of the quick-freezing machine that has completed the quick-freezing process to idle.

[0091] Specifically, the host computer receives the status information of each quick freezer. When the quick freezer completes the quick freezing of blood, the host computer calls the transport device to take the blood that has been quick frozen from the quick freezer. The host computer controls the transport device to come to the location of the quick freezer that has completed the quick freezing process according to the third path. The transport device interacts with the quick freezer through the host computer. The transport device and the quick freezer cooperate with each other under the coordination of the host computer to take the blood out of the cold table of the quick freezer.

[0092] like Figure 5 As shown, in some embodiments, step S302 may include but is not limited to steps S501 to S502.

[0093] Step S501: Select an idle transport device that is closest to a calling terminal that issues a call request, and generate a first path according to a current position of the selected transport device and a position of the calling terminal that issues the call request.

[0094] Step S502: Select an idle or soon-to-be-idle quick-freezer, and generate a second path according to the location of the selected quick-freezer and the location of the calling terminal that issues the call request.

[0095] Figure 6 is a flow chart of a blood quick freezing method according to a third embodiment of the present invention, wherein Figure 3 Based on the examples, Figure 6 The method may include but is not limited to steps S601 to S605.

[0096] Step S601, determine whether all quick freezers are currently not idle. If yes, execute step S602; if not, execute step S603.

[0097] Step S602, waiting for the quick-freezing machine to perform quick-freezing treatment on the blood. Return to step S601.

[0098] Step S603, generating a fourth path and a fifth path, the fourth path is a route from the calling terminal to the waiting area, and the fifth path is a route from the waiting area to an idle quick freezer.

[0099] Step S604, controlling the transport device loaded with blood to move along the fourth path and placing the blood in the waiting area.

[0100] Step S605, when the quick freezer is idle, control the idle transport equipment to load the blood in the waiting area, and control the transport equipment loaded with blood to move along the fifth path to put the loaded blood into the idle quick freezer.

[0101] In summary, according to the blood quick-freezing system and method of the embodiments of the present invention, the transport equipment is controlled to transport blood from the component separation area to the quick-freezing area and automatically navigate to the corresponding quick-freezing machine. The host computer realizes data interaction between the transport equipment and the quick-freezing machine.
