Description

Technical Field

[0001] The present invention relates to the technical field of blood storage, and in particular to a turntable-type automated blood storage device and a storage and access method. Background Art

[0002] Blood is typically stored in blood banks, maintained by medical institutions, blood stations, or the Red Cross, for use when transfusions are needed. Due to the uncertain clinical demand for blood and the varying blood types and components required, cryogenic storage technologies that extend the shelf life of blood and its components are gaining increasing attention.

[0003] Currently, blood storage primarily relies on traditional refrigerators or cold storage facilities. These facilities utilize three-dimensional shelves within the refrigerator or cold storage, with pallets placed horizontally on the shelves and blood bags placed horizontally within the pallets. When storing and retrieving blood, a stacker is required to retrieve and place pallets. This requires space within the refrigerator or cold storage for the stacker's movement, resulting in a large overall size and footprint. Within a given refrigerator or cold storage space, the actual space available for blood storage is limited, resulting in low space utilization. Multiple blood bags are stored horizontally on a single pallet. When blood is collected, a stacker removes the entire pallet, and a human identifies and removes the required blood. The remaining blood is then returned to the storage facility. When blood is frequently needed, the frequent movement of blood between the cold storage environment and the outside world not only impacts the cold storage environment within the cold storage facility but also compromises the blood's storage quality.

DETAILED DESCRIPTION

[0069] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0070] The present invention discloses a turntable type automatic blood storage device, referring to Figure 1 , including a control unit 300, a refrigeration unit 400, a cold storage 500, a mechanical unit 100, an input unit 600, an output unit 700 and a detection unit 800, wherein the refrigeration unit 400 is directly connected to the cold storage 500 and can directly operate the cold storage 500; the control unit 300 is respectively connected to the refrigeration unit 400, the mechanical unit 100, the input unit 600 and the output unit 700; the control unit 300 controls the refrigeration unit 400 to adjust the temperature and humidity in the cold storage 500; the control unit 300 receives instructions from the user through the input unit 600, and controls the mechanical unit 100 to perform refrigeration; the control unit 300 transmits the execution results and the working status of the refrigeration unit 400, the mechanical unit 100 and the cold storage 500 to the output unit 700, and displays them to the user through the output unit 700. The detection unit 800 is connected to the refrigeration unit 400, the mechanical unit 100 and the cold storage 500 respectively, detects the working status of the refrigeration unit 400, the mechanical unit 100 and the cold storage 500, and feeds it back to the control unit 300 and the refrigeration unit 400 respectively.

[0071] The core of the refrigeration unit 400 is a refrigeration device, whose function is to transfer heat from the inside of the cold storage 500 to the outside, thereby lowering the temperature of the cold storage 500 to reach the temperature environment required for blood storage.

[0072] Input unit 600 includes buttons and a receiving unit for receiving user commands or data via a network. This allows the operator to input control commands and data, such as the type, quantity, and date of blood being deposited, the type of blood to be withdrawn, and storage optimization strategies. Storage optimization strategies refer to the storage method, location, duration, and conditions for retrieval of blood bags. For example, type A blood may be stored on a specific shelf for one year, and blood bags may be retrieved on a first-in, first-out basis.

[0073] The output unit 700 uses a liquid crystal display (LCD), a light-emitting diode (LED), a vibration device, a sound module, etc. to display certain specific information to the user, such as data, images, light and shadow, movement, sound, etc. The user can interact with the storage device according to the prompts of this information. For example, the user places the blood bag in a designated position according to the prompts on the LCD screen so that the robot 122 can grab it and put it on the shelf.

[0074] The detection unit 800 is a key component for ensuring stable operation of all system components and reducing operational errors and faults. It is composed of various sensors and detection devices, such as temperature sensors, proximity switches or sensors, voltage and current detection devices, and motor detection devices. The detection unit 800 is equipped with a barcode or RFID detection device at the access port 510 of the cold storage 500, capable of identifying the barcode or RFID tag on the blood bag. In this embodiment, the identification device (such as a barcode reader) for identifying the barcode or RFID tag data on the blood bag is located on the manipulator 122 or on the detection cartridge 210 in the blood quality detection unit 200. The detection cartridge 210 is located on the manipulator 122. This allows the manipulator 122 to simultaneously read blood information when it grasps the storage cartridge 900, improving access efficiency.

[0075] Ensuring stable operation of all parts of the system refers to detecting the temperature in the cold storage 500, the working status of the refrigeration unit 400, and the working status of the mechanical unit 100, and transmitting the above detection results to the control unit 300. The control unit 300 issues instructions for the next step of work in real time according to the detected status of each part.

[0076] Reducing operational errors and mistakes means that the blood bag undergoes necessary inspections at the access port 510, such as checking the type and weight of the blood, confirming that the storage box 900 is empty before placement, and confirming that the storage box 900 is indeed filled after placement. In addition to optical sensors, the detection device that reduces operational errors and mistakes requires intelligent recognition methods such as barcode recognition, radio frequency identification, and visual recognition.

[0077] The control unit 300 is a key component of the system, driving other parts to complete related operations according to instructions, monitoring and confirming the operating status of each part through the detection unit 800, and also entering and processing data to achieve better management of blood.

[0078] The actions and operations include but are not limited to grabbing the storage box 900 and placing it into the designated storage position 112 on the shelf, taking out the storage box 900 from the designated storage position 122 on the shelf, rotating the shelf when placing or taking out the storage box 900, opening and closing the door of the access port 510, etc.

[0079] The cold storage 500 is a vertical closed cylindrical structure, and the mechanical unit 100 is built into the cold storage 500. The access port 510 on the cold storage 500 can be a vertical long door arranged along the height direction of a certain shelf 111. When the access port 510 is opened, the storage positions 112 on the shelf 111 directly opposite the access port 510 are all visible. After the manipulator 122 grasps the storage box 900, it does not need to move up and down. It can directly rotate horizontally to move the storage box 900 into / out of the storage position. This method needs to be used in conjunction with a liftable access platform. Because the access port 510 has a certain height, the operator may not be able to reach the storage box 900 placed on the access port 510. Through the liftable storage platform, the storage box 900 is placed on the access platform, and the access platform is lifted and lowered to a height range within which the operator can operate. Alternatively, if the access opening 510 is shorter than the shelf 111, only the portion of the storage space 112 directly opposite the access opening 510 is visible when the access opening 510 is open. After the robot 122 has grasped a storage box 900, it must move left and right, bringing the box directly opposite the access opening 510 and then rotating it horizontally before it can be moved in and out of the storage space. While a smaller access opening 510 requires the robot 122 to move horizontally, it reduces the amount of cooling air leaking out each time the door is opened, saving energy.

[0080] Reference Figure 2 and Figure 3The mechanical unit 100 is built into the cold storage 500 and includes a shelf assembly 110 and a grabbing and moving assembly 120. The shelf assembly 110 is mainly used to store blood bags and rotate the target shelf 111 to a position facing the access port 510 so that the grabbing and moving assembly 120 can grab the storage box 900; the grabbing and moving assembly 900 is mainly used to grab the storage box 900 and move the storage box 900 from the shelf 111 to the access port 510, or move the storage box 900 from the access port 510 back to the shelf 111.

[0081] The grabbing and moving assembly 120 includes a track 121 arranged in a horizontal direction and a manipulator 122 that reciprocates along the track 121. The manipulator 122 can also rotate horizontally relative to the track 121. The manipulator 122 and the track 121 can achieve horizontal rotation through a rotating shaft 123. The manipulator 122 clamps the storage box 900, moves the storage box 900 into the storage position 112, or moves it out from the storage position 122 to the access port 510 of the cold storage 500.

[0082] The shelf assembly 110 includes a central rotating shaft 113, which is perpendicular to the ground. Multiple partitions 111 are spaced apart from each other from top to bottom. Between adjacent partitions 111 are multiple storage locations 112 for blood bags 001. Each storage location 112 is provided with a removable storage box 900, in which blood bags 001 are placed. Rotation of the central rotating shaft 113 drives the partitions 111 mounted thereon to rotate synchronously, achieving synchronous rotation of the storage locations 112 mounted on the partitions 111. The rotation of the central rotating shaft 113 is achieved through the following structure: the mechanical unit 100 also includes a drive motor, the output shaft of which is connected to a driving gear, which meshes with a driven gear, with the lower end of the central rotating shaft 113 meshing with the driven gear.

[0083] Between every two adjacent partitions 111, multiple storage locations 112 are arranged in a fan-shaped pattern around a central rotation axis 113. Each storage location 112 comprises an upper plate 1121 and a lower plate 1122, positioned in a vertically opposed relationship. The storage box 900 is removably inserted between these two plates. The upper and lower plates 1121, 1122 can be independent components of the partitions 111 or integrated with them. To facilitate access to the storage box 900, the multiple storage locations 112 in each layer are aligned vertically.

[0084] The structural diagram of the storage box 900 is shown in FIG. Figure 4The storage box 900 includes a back plate 910 and a housing 920 mounted thereon. An opening is formed at the top of the housing 920, through which the blood bag 001 is moved into and out of the housing 920. The back plate 910 is removably inserted between an upper plate 1121 and a lower plate 1122. The back plate 910 is provided with a first transparent region 930 and a second transparent region 940, arranged from top to bottom. The first transparent region 930 allows the light source 220 to illuminate the spectral recognition sensor 230 through the blood's interfacial region and through the first transparent region 930, when the blood quality detection unit 200 employs the spectral recognition sensor 230. The second transparent region 940 ensures that, when the blood bag 001 is placed within the storage box 900, the identification code on the blood bag 001 faces the second transparent region 940, allowing the identification device (e.g., the code reader 810) in the detection unit 800 to scan the identification code. The height of the back plate 910 is higher than that of the box body 920. When the blood bag 001 is placed in the box body 920, the blood stratification interface area in the blood bag 001 extends out of the box body 920. This makes it easier for the spectral recognition sensor 230 in the blood quality detection unit 200 to obtain the blood stratification interface spectrum or the visual recognition sensor 240 to obtain the blood stratification interface image.

[0085] There are two implementation forms of the plug-in structure between the back plate 910 and the upper plate 1121 and the lower plate 1122, which are:

[0086] The first one, refer to Figure 5 and Figure 6 The upper plate 1121 and lower plate 1122 each have grooves 1123, into which the ends of the back plate 910 are inserted. Furthermore, protrusions 1126 are provided at each end of the lower plate 1122 to seal the ends of the grooves 1123 on the lower plate 1122. When the storage box 900 is inserted into the grooves 1123, a certain gap exists between the upper end of the back plate 910 and the upper plate 1121. When the manipulator 122 grabs the storage box 900 from the storage position 112 and removes it, the operation process is as follows: the manipulator 122 grabs the storage box 900; lifts the storage box 900 upward, and removes the lower end of the back plate 910 from the groove 1123 on the lower plate 1122; and then slides the storage box 900 along the groove 1123 on the upper plate 1121 to remove it. The protrusions 1126 prevent the storage box 900 from sliding off the storage position 112, thereby improving the reliability of the device. When the manipulator 122 places the storage box 900 on the storage position 112, the action process is: the manipulator 122 clamps the storage box 900; under the push of the manipulator 122, the upper end of the back plate 910 of the storage box 900 slides inward along the groove 1123 of the upper plate 1121; the storage box 900 is moved downward, and the lower end of its back plate 910 is inserted into the groove 1123 on the lower plate 1122.

[0087] The second one, refer to Figure 7 and Figure 8 The upper plate 1121 and the lower plate 1122 are each provided with a groove 1123. A return spring 1124 and a ball 1125 are provided in the groove 1123 of the lower plate 1122. The ball 1125 is located at one end of the return spring 1124. The lower end of the back plate 910 is provided with a recessed portion (not shown) adapted for the ball 1125. When the two ends of the back plate 910 are inserted into the groove 1123, the ball 1125 is sunken into the recessed portion. When the manipulator 122 moves the storage box 900 out of / into the storage position 112, the manipulator 122 clamps the storage box 900 and drags it along the groove 1123, causing the ball 1125 to slide out / into the recessed portion. Compared with the first method, the second method is more convenient and faster to operate, eliminating the need to lift or lower the storage box 900. Furthermore, the cooperation between the recessed portion and the ball 1125 makes the storage box 900 more stable on the storage position 112 and less likely to shake.

[0088] The rotary disk type automated blood storage device also includes a blood quality detection unit 200, which is used to detect the stratification interface of the blood in the blood bag 001 and judge the blood quality based on the stratification interface of the blood. When the blood quality does not meet the standard, an alarm is issued to prompt human intervention.

[0089] The structural diagram of the blood quality detection unit 200 is shown in FIG. Figure 9 , including a detection box 210 with an opening on one side, a detection component and an analysis module arranged on the detection box 210, the clamping part 1221 of the manipulator 122 is located inside the detection box 210, the clamping part 1221 is used to clamp the storage box 900, the detection component is used to obtain the stratification interface of the blood and send the stratification interface of the blood to the analysis module, the analysis module includes a teaching model, the analysis module analyzes and compares the received blood stratification interface with the teaching model, and judges the quality of the blood.

[0090] There are two forms of detection components, namely, using spectral recognition sensors or visual recognition sensors.

[0091] The first type is the detection component using a spectral recognition sensor, referring to Figure 10 and Figure 11A light source 220 and a spectrum recognition sensor 230 are respectively provided on two opposing side walls of the detection box 210. The light source 220 is located on the side away from the back plate 910, while the spectrum recognition sensor 230 is located on the side closer to the back plate 910 and facing the first transparent area 930. Light emitted from the light source 220 passes through the interfacial region of the blood bag 001 and through the first transparent area 930 to the spectrum recognition sensor 230, which then acquires the interfacial spectrum of the blood. When the blood bag 001 is placed in the storage box 900, the interfacial region of the blood extends beyond the box body 920, allowing the spectrum recognition sensor 230 to successfully acquire the interfacial spectrum.

[0092] During testing, the light source 220 illuminates the layered interface area of the blood bag 001; the light emitted by the light source 220 passes through the layered interface area of the blood and passes through the first transparent area 930 to the spectrum recognition sensor 230. The spectrum recognition sensor 230 obtains the layered interface spectrum of the blood and uploads the layered interface spectrum data to the analysis module; the analysis module compares and analyzes the received layered interface spectrum with the teaching model to determine whether the blood quality meets the standard.

[0093] To improve the quality of the delamination interface spectrum, the distance between the light source 220 and the blood bag 001 and the distance between the spectrum recognition sensor 230 and the blood bag 001 are the same. Furthermore, the distance between the two side walls of the detection box 210 and the storage box 900 is 2-5 cm. This means that the distance between the light source 220 and one side of the blood bag 001 and the distance between the spectrum recognition sensor 230 and the other side of the blood bag 001 are 2-5 cm. The area receiving the light from the spectrum recognition sensor 230 covers half of the blood bag 001, ensuring that the delamination interface spectrum can be detected for blood bags of varying capacities and positioned at different angles within a certain range.

[0094] The detection box 210 with only one side opening forms a relatively closed space, which can ensure the stability of the light source and avoid recognition errors caused by position changes or changes in external light sources.

[0095] The second type is to use a visual recognition sensor as the detection component. Figure 12 and Figure 13 A visual recognition sensor 240 is located on a side wall of the detection box 210, away from the back plate 910. This sensor captures an image of the blood's interlayer interface. When the blood bag 001 is placed in the storage box 900, the blood's interlayer interface extends beyond the box body 920, allowing the visual recognition sensor 240 to successfully capture the image.

[0096] During the detection, the visual recognition sensor 240 on one side of the blood bag 001 captures the layered interface image and uploads the layered interface image data to the analysis module; the analysis module compares and analyzes the received layered interface image with the teaching model to determine whether the blood quality meets the standards.

[0097] To improve the quality of the layered interface image, the distance between the two side walls of the detection box 210 and the storage box 900 is 2-5 cm. This also means that the distance between the visual recognition sensor 240 and one side of the blood bag 001 is 2-5 cm. The area of the blood bag imaged by the visual recognition sensor 240 covers half of the blood bag, ensuring that the layered interface image can be captured for blood bags of varying capacities and placed at different angles within a certain range.

[0098] The detection box 210 with only one side opening forms a relatively closed space, which can ensure the stability of the light source and avoid image capture errors caused by position changes or changes in external light sources.

[0099] The storage method applied to the above-mentioned rotary disk type automated blood storage device is as follows: Figure 15 :

[0100] First, in step 101, the system is powered on;

[0101] In step 102, the status of each part of the system is monitored and adjusted. The detection unit 800 collects the operating status of each part and feeds it back to the control unit 300. The control unit 300 adjusts the status of each part based on the returned information and preset values. For example, if the temperature of the cold storage 500 is too high, the control unit 300 will control the refrigeration unit 400 to cool until the temperature of the cold storage 500 collected by the detection unit 800 reaches the standard value.

[0102] In step 103, the detection unit 800 monitors whether there is an instruction input. If there is no input in the input unit 600, the process returns to step 102; if there is input in the input unit 600, the process proceeds to the next step.

[0103] In step 104, when the detection unit 800 detects input from the input unit 600, it parses the input command. If the input command is to store blood, the blood storage command processing is executed: first, the control unit 300 allocates a storage location 112 for the blood in the cold storage 500 according to relevant strategies, such as storage optimization measurement; then the control unit 300 drives the mechanical unit 100 to grab the storage box 900 on the above-mentioned designated storage location 112 and move it to the access port 510; the output unit 700 prompts the user to put the blood bag 001 into the storage box 900; the detection unit 800 detects whether the blood bag 001 is placed in the storage box 900 and reads the barcode or RFID electronic tag data on the blood bag 001; if the detection unit 800 does not detect that the blood bag 001 is placed in the storage box 900, or does not read the blood bag 001, the output unit 700 will continue to prompt the user to put in the blood bag 001; if the detection unit 800 detects that the blood bag 001 is placed in the storage box 900 and reads the barcode or RFID electronic tag data on the blood bag 001, the output unit 700 will display the blood information according to the barcode or RFID electronic tag data and prompt the user to confirm; after the user confirms, the control unit 300 will control the mechanical unit 100 to move the storage box 900 with the blood bag 001 back to the designated storage position 112; the control unit 300 records the blood information, storage time, storage location and other data, and returns to step 102.

[0104] During the storage of blood in the cold storage 500, the blood quality detection unit 200 will monitor the changes in blood quality. There are two specific implementation forms:

[0105] The first method uses a spectral recognition sensor or a visual recognition sensor. When the blood bag 001 is placed in the storage box 900, the control unit 300 will control the blood quality detection unit 200 to obtain the stratification interface status data of the current blood; in the subsequent blood storage process, according to the interval time T set by the system, the control unit will control the blood quality detection unit 200 to obtain the stratification interface status data of the blood in each blood bag 001 at each interval T, and upload the stratification interface status data to the analysis module; the analysis module compares and analyzes the received stratification interface status data with the teaching model to judge the blood quality.

[0106] The second method is to use a pressure sensor. The principle of using a pressure sensor is that as the blood is stored for a longer time, the blood will undergo a qualitative change, which will bring about a change in blood volume, thereby causing a change in the pressure of the blood bag 001. The blood quality can be judged by detecting the pressure change of the blood bag 001. Figure 14, pressure sensors 250 are respectively provided on the two side walls of the storage box 900. When the blood bag 001 is placed in the storage box 900, the control unit 300 controls the two pressure sensors 250 to start at the same time and starts to detect the current pressure of the blood bag 001; when the pressure sensor 250 detects a pressure value between 0-0.05Pa, the pressure sensor 250 uploads the current pressure value to the analysis module; during the storage process of the blood, the pressure sensor 250 detects the pressure of the blood bag 001 in real time. When the pressure value detected by the pressure sensor 250 exceeds the system setting value, the analysis module analyzes that the blood quality at this time does not meet the standard, and sends the analysis result to the control unit 300, and the control unit 300 issues a blood quality alarm.

[0107] If the blood quality detection unit 200 detects substandard blood, the analysis module sends the analysis results to the control unit 300, which issues a blood quality alarm. The output unit 700 displays information about the substandard blood, prompting the user to remove the substandard blood promptly. If the substandard blood cannot be removed promptly, the control unit 300 locks the substandard blood and prohibits its release from the warehouse.

[0108] If the input command is to draw blood, the blood drawing command processing is executed: first, the control unit 300 determines the position of the storage location 112 where the blood that best meets the requirements is located according to relevant strategies, such as storage optimization strategies; the control unit 300 controls the movement of the shelf assembly 110 in the mechanical unit 100 to move the row where the designated storage location 112 is located to a position facing the access port 510; the control unit 300 controls the grabbing and moving assembly 120 in the mechanical unit 100 to grab the storage box 900 on the designated storage location 112, and detects whether there is a blood bag 001 in the storage box 900; if the detection unit 800 does not detect the blood bag 001, then Record and re-search and locate the blood bag that best meets the requirements; if the detection unit 800 detects blood bag 001, the grabbing and moving component 120 moves the storage box 900 to the access port 510, and reads the barcode or RFID electronic tag data on the blood bag 001 at the same time. The output unit 700 displays the blood information according to the barcode or RFID electronic tag data, and prompts the user to confirm and take blood; after the user confirms and takes blood, the grabbing and moving component 120 puts the empty storage box 900 back to the designated storage position 112, and the control unit 300 records the blood information, removal time and location information and other data, and returns to step 102.

[0109] Figure 16 This is a diagram of the work flow of turntable automated blood storage. The blood storage work flow refers to the process of placing blood bags into the cold storage for storage. Figure 16 , the turntable-type automated blood storage workflow of the present invention is described in detail:

[0110] First, in step 201, the system receives blood storage instruction information such as the number of blood bags to be stored, the type of blood bags to be stored, and the blood collection time, input by the operator through the input unit 600;

[0111] In step 202, the control unit 300 allocates storage space for the blood bag 001 to be stored in the cold storage 500 according to the information received from the input unit 600 and in accordance with relevant internally stored policies, such as a storage optimization policy, and determines the location of the storage position 112 where the storage box 900 to store the blood bag 001 is located.

[0112] In step 203, the mechanical unit 100 receives the instruction from the control unit 300 and rotates the row of designated storage locations 112 to a position directly opposite the access port 510. The specific operation is as follows: the drive motor in the mechanical unit 100 moves, driving the driving gear and the driven gear to move until the row of designated storage locations 112 is rotated to a position directly opposite the access port 510.

[0113] In step 204, the mechanical unit 100 receives the instruction from the control unit 300 and moves the storage box 900 on the designated storage location 112 to the access port 510. The specific steps are as follows:

[0114] (a) The robot arm 122 of the mechanical unit 100 moves vertically along the guide rail 121 to the front of the storage box 900;

[0115] (b) the robot arm 122 extends and grips the storage box 900 , and the robot arm 122 moves the storage box 900 out of the storage position 112 ;

[0116] (c) The robot 122 moves the storage box 900 to a position facing the access port 510;

[0117] (d) The robot arm 122 rotates horizontally to move the storage box 900 to the access port 510;

[0118] In step 205, the user places the blood bag into the storage box 900 according to the prompt of the output unit 700. The detection unit 800 detects whether blood bag 001 is placed in the storage box 900. If blood bag 001 is not detected or the barcode or RFID electronic tag data on blood bag 001 is not read, the output unit 700 will continue to prompt the user to place blood bag 001. If the detection unit 800 detects that blood bag 001 is placed in the storage box 900 and reads the barcode or RFID electronic tag data on blood bag 001, the output unit 700 will display the blood information according to the barcode or RFID electronic tag data and prompt the user to confirm.

[0119] In step 206 , the mechanical unit 100 receives the instruction from the control unit 300 and moves the storage box 900 containing the blood bag 001 from the access port 510 back to the designated storage position 112 ;

[0120] In step 207, the blood quality detection unit 200 detects the stratified interface of the blood in the newly placed blood bag 001 or the pressure value of the blood bag, and uploads the data to the analysis module;

[0121] In step 208, the control unit 300 records the blood information, storage time, storage location, and other data, and the blood bag is stored in the warehouse. The blood information includes initial blood quality information, such as the initial blood layer interface spectrum or layer interface image or the initial pressure value of the blood bag.

[0122] At step 209, during subsequent blood storage, the control unit 300 controls the blood quality detection unit 200 to obtain data on the stratified interface of the blood in each blood bag 001 at intervals T set by the system, and uploads the data to the analysis module. The analysis module compares and analyzes the received stratified interface data with the taught model to determine the blood quality. Alternatively, the pressure sensor 250 monitors the pressure of the blood bag 001 in real time. When the pressure value detected by the pressure sensor 250 exceeds the system-set value, the analysis module determines that the blood quality does not meet the standard. If the blood quality detection unit 200 detects that the blood quality does not meet the standard, the analysis module sends the analysis result to the control unit 300, which issues a blood quality alarm. The output unit 700 displays information about the substandard blood, prompting the user to remove the substandard blood promptly. If the substandard blood cannot be removed promptly, the control unit 300 locks the substandard blood and prohibits its release from the storage.

[0123] Figure 17 For the blood removal workflow diagram of the present invention, reference will be made below Figure 17 , the blood removal workflow of the present invention is described in detail:

[0124] First, in step 301, the system receives blood collection request information such as the number, type, and blood collection time of the blood bags to be collected by the operator through the input unit 600;

[0125] In step 302, the control unit 300 determines the location of the storage box 900 to be taken out in the cold storage 500 according to the information received from the input unit 600 and the relevant internally stored strategy, such as the storage optimization strategy;

[0126] In step 303, the mechanical unit 100 receives the instruction from the control unit 300 and rotates the row of designated storage locations 112 to a position directly opposite the access port 510. The specific operation is as follows: the drive motor in the mechanical unit 100 moves, driving the driving gear and the driven gear to move until the row of designated storage locations 112 is rotated to a position directly opposite the access port 510.

[0127] In step 304, the detection unit 800 detects the designated storage box 900 to determine whether there is a blood bag 001 inside the storage box 900 and sends the detection result to the control unit 300. If the detection unit 300 does not detect the blood bag 001, the detection unit 800 records the result and searches for and locates a blood bag that best meets the requirements. If the detection unit 800 detects the blood bag 001, the detection unit 800 reads the barcode or RFID tag data on the blood bag 001, and the output unit 700 displays the blood information based on the barcode or RFID tag data.

[0128] In step 305, the mechanical unit 100 receives the instruction from the control unit 300 and moves the storage box 900 on the designated storage location 112 to the access port 510. The specific steps are as follows:

[0129] (a) The robot arm 122 of the mechanical unit 100 moves vertically along the guide rail 121 to the front of the storage box 900;

[0130] (b) the robot arm 122 extends and grips the storage box 900 , and the robot arm 122 moves the storage box 900 out of the storage position 112 ;

[0131] (c) The robot 122 moves the storage box 900 to a position facing the access port 510;

[0132] (d) The robot arm 122 rotates horizontally to move the storage box 900 to the access port 510 .

[0133] In step 306, the control unit 300 records the blood information, storage time, and storage location data in the cold storage 500, and the blood removal is completed.

[0134] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
