[0002] Blood is usually stored in a blood bank, which is kept by medical institutions, blood stations or the Red Cross for use when blood transfusion is needed. Since the clinical demand for blood is uncertain and the required blood types or component blood types vary, the cryogenic refrigeration technology for extending the shelf life of blood and component blood has received increasing attention. At present, the storage of blood mainly relies on traditional refrigerators. Shelves are arranged inside the refrigerator, and blood bags are placed in blood boxes and arranged on the shelves to achieve the storage of blood. When accessing blood, usually, an operator manually opens the cabinet door, finds the corresponding position on the shelf to access the blood box. The degree of automation is low, the efficiency is low, and when the cabinet door of the refrigerator is opened, due to the large temperature difference with the outside world, a large amount of cold air will be lost, resulting in unnecessary energy consumption. At the same time, the large change range of the internal temperature of the refrigerator will also affect the quality of blood storage. Summary of the Invention

[0020] In the description of the present invention, "a plurality" means more than two. If there is a description of first and second, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features or the sequence relationship of the indicated technical features.

[0021] In the description of the present invention, unless otherwise clearly defined, terms such as "set", "installed", "connected", etc. should be understood in a broad sense. Those skilled in the art can reasonably determine the specific meanings of the above terms in the present invention in combination with the specific content of the technical solution.

[0022] Referring to Figures 1 to 4 As shown, an automated three-dimensional blood bank according to an embodiment of the present invention includes a refrigerated cabinet 100 and a plurality of shelf units 200.

[0023] The interior of the refrigerated cabinet 100 defines a refrigerated chamber. The refrigerated cabinet 100 is provided with a plurality of access openings 101 on the front side of the refrigerated chamber, and opening and closing doors 110 are provided at the access openings 101. The opening and closing doors 110 are used to open or close the access openings 101. It can be understood that the access openings 101 are used for a single blood box 300 to pass through, and the cross-sectional dimension of the access openings 101 is slightly larger than the cross-sectional dimension of the blood box 300. The refrigerated cabinet 100 is provided with an air conditioner to adjust the temperature inside the refrigerated cabinet 100. In some embodiments, the opening and closing doors 110 are connected to a telescopic motor to control the opening and closing of the opening and closing doors 110. Of course, the telescopic motor can be replaced by a hydraulic cylinder or an oil cylinder, which is a conventional technical means and will not be elaborated here. In addition, in order to ensure the sealing performance, sealing structures such as sealing rubber strips can be provided at the opening and closing doors 110 and the access openings 101.

[0024] The shelf units 200 correspond to the access openings 101 one by one, that is, one shelf unit 200 corresponds to one access opening 101, and the access opening 101 is located directly in front of the corresponding shelf unit 200. Specifically, the shelf unit 200 includes a storage rack 210, a carrier tray 220, a rotation driving device 230, and a pushing device 240.

[0025] Among them, the storage rack 210 is arranged inside the refrigerator 100.

[0026] The storage tray 220 is horizontally arranged on the storage rack 210. The center line of the storage tray 220 extends vertically. The storage tray 220 can rotate around its own vertical center line. The storage tray 220 is used to support the blood box 300. A plurality of limiting components are arranged on the storage tray 220 along the circumferential direction. A storage position for storing the blood box 300 is defined between the limiting components and the upper surface of the storage tray 220. A plurality of limiting components correspondingly define a plurality of storage positions. The plurality of storage positions are arranged along the circumferential direction of the storage tray 220. In addition, the limiting components can move relative to the storage tray 220 so that the size of the storage position is adjustable, so as to store blood boxes 300 of different specifications. It should be noted that the function of the limiting components is to limit the blood box 300 so that the blood box 300 has a stable state when stored. Obviously, the limiting components can release the limit on the blood box 300 so that the blood box 300 can be pushed out of the storage position.

[0027] The rotation driving device 230 is connected to the storage tray 220. The rotation driving device 230 can drive the storage tray 220 to rotate so that any storage position faces the access opening 101.

[0028] The pushing device 240 is arranged on the storage rack 210 and has the freedom of moving back and forth. The pushing device 240 is used to push the blood box 300 in the storage position facing the access opening 101 to the access opening 101.

[0029] Based on the above embodiments, when performing a blood-taking operation, that is, when taking out the blood box 300, the rotation driving device 230 is used to drive the storage tray 220 to rotate so that the storage position corresponding to the blood box 300 to be taken out faces the access opening 101. Then, the opening and closing door 110 is opened, and the pushing device 240 is used to push the blood box 300 from the storage position to the access opening 101. After the pushing is completed, the pushing device 240 resets. Then, the operator takes away the blood box 300 at the access opening 101, and finally closes the opening and closing door 110. When storing the blood box 300, the rotation driving device 230 is used to drive the storage tray 220 to rotate so that the empty storage position faces the access opening 101. Then, the opening and closing door 110 is opened, and the operator inserts the blood box 300 from the access opening 101 into the storage position, and the limiting components are used to limit the blood box 300. Finally, the opening and closing door 110 is closed to complete the blood storage operation.

[0030] For the automated three-dimensional blood bank configured with the above structure, only a relatively small access opening 101 needs to be provided in front of the refrigerator cabinet 100 to perform the access operation of the blood box 300, which can reduce the heat exchange during the access process, reduce the loss of cold air in the refrigerator cabinet 100, and result in low energy consumption. Moreover, when taking out the blood box 300, only need to drive the carrier tray 220 to rotate through the rotation driving device 230 so that the corresponding storage position faces the access opening 101, and then push out the blood box 300 through the pushing device 240. When storing the blood box 300, only need to drive the carrier tray 220 to rotate through the rotation driving device 230 so that the vacant storage position faces the access opening 101, and then the operator can insert the blood box 300 into the storage position. The entire operation process is completed in front of the access opening 101, with a high degree of automation, convenient access of the blood box 300, and high access efficiency. In addition, the storage position for storing the blood box 300 is defined by the limiting component and the carrier tray 220, and the limiting component can move relative to the carrier tray 220 so that the size of the storage position can be changed. In this way, it can be used to store blood boxes 300 of different sizes and specifications, with a wide range of applications and strong practicability.

[0031] It can be conceived that for the convenience of installation and maintenance, the refrigerator cabinet 100 can be split into a cabinet body 102 and a front panel 103, for example Figure 2 As shown, a cavity with a front-side opening is formed inside the cabinet body 102, the front panel 103 is detachably arranged on the front side of the cabinet body 102, and the access opening 101 is formed on the front panel 103.

[0032] It can be conceived that in order to ensure the stability of the blood box 300 when it is pushed out to the access opening 101, a support plate can be provided on the front side of the access opening 101 to support the blood box 300 when the blood box 300 is pushed out.

[0033] Next, the structure of the limiting component will be described with reference to the accompanying drawings.

[0034] Refer to Figure 5 As shown, in some embodiments of the present invention, the limiting component includes a first limiting portion 250 and a second limiting portion 260. There are two first limiting portions 250, and the storage position is formed between the upper surface of the carrier tray 220, the two first limiting portions 250 and the second limiting portion 260.

[0035] Specifically, two first limiting portions 250 of the same group are oppositely arranged along the circumferential direction of the carrier tray 220 on the carrier tray 220, and the two second limiting portions 260 can be adjusted to move towards or away from each other so that the distance between the two first limiting portions 250 can be changed; the two first limiting portions 250 are used to cooperate to clamp the blood box 300. In this embodiment, when the blood box 300 is stored in the storage position, the two first limiting portions 250 clamp the blood box 300 from the thickness direction of the blood box 300.

[0036] The second limiting part 260 is vertically adjustably arranged on the upper side between the two first limiting parts 250. A limiting groove 261 is arranged at the bottom end of the second limiting part 260. The limiting groove 261 is enclosed on the opposite two sides and the upper side along the radial direction of the loading tray 220. The limiting groove 261 is used for the top of the blood cartridge 300 to be embedded. By arranging the limiting groove 261, it can be used to limit the vertical displacement of the blood cartridge 300 and the displacement of the blood cartridge 300 along the radial direction of the loading tray 220. In this way, the random movement of the blood cartridge 300 can be avoided, the stability of the storage of the blood cartridge 300 can be ensured, and at the same time, the blood cartridge 300 can be prevented from moving to a position where it interferes with the loading tray 220, avoiding affecting the rotation of the loading tray 220. In this embodiment, when the storage position is directly opposite to the access opening 101, the opposite two sides along the radial direction of the loading tray 220 of the limiting groove 261 are the front and rear sides of the limiting groove 261.

[0037] In this embodiment, by arranging the two movable first limiting parts 250 and the movable second limiting part 260 to form a storage position with the upper surface of the loading tray 220, on the one hand, the blood cartridge 300 can be limited from all directions to ensure the stability of the storage of the blood cartridge 300. On the other hand, the size of the storage position can be changed by moving the first limiting part 250 and the second limiting part 260, so that it can be applicable to blood cartridges 300 of different specifications and improve the applicable range.

[0038] Based on the above embodiments, it can be imagined that the movement of the first limiting part 250 can be realized by electric drive or other power drive forms. Of course, in order to reduce costs and avoid overly complex control, other non-power drive forms can also be adopted.

[0039] For example, in some embodiments of the present invention, referring to Figure 5 、 Figure 7 and Figure 9 as shown, the first limiting part 250 is horizontally slidably arranged on the loading tray 220. The limiting component further includes two first elastic members 270. The two first elastic members 270 act on the two first limiting parts 250 respectively, so that the two first limiting parts 250 can move towards each other. Through the action of the two first elastic members 270, the two first limiting parts 250 can clamp the blood cartridge 300. Among them, the two first limiting parts 250 are respectively provided with a clamping surface 251 and a first guiding surface 252 on their opposite sides. The clamping surface 251 is perpendicular to the sliding direction of the first limiting part 250. The clamping surface 251 is used for contacting the side surface of the blood cartridge 300. The first guiding surface 252 is located at one end of the clamping surface 251 away from the center of the loading tray 220. The first guiding surfaces 252 of the two first limiting parts 250 extend obliquely in the direction away from each other and are used for abutting against the blood cartridge 300 during the process of the blood cartridge 300 being deposited into the storage position.

[0040] Specifically, when the storage position is directly opposite the access port 101, the two first limiting portions 250 are distributed relatively on the left and right. The first elastic member 270 applies an elastic force to the first limiting portions 250 in the left-right direction. The clamping surface 251 is perpendicular to the left-right direction. The first guiding surface 252 is located on the front side of the clamping surface 251. During the process of inserting the blood cartridge 300 from the access port 101 to the storage position, the blood cartridge 300 first contacts the first guiding surfaces 252 of the two first limiting portions 250. Since the first guiding surfaces 252 are inclined, the blood cartridge 300 can move along the first guiding surfaces 252, thereby pushing open the two first limiting portions 250 and causing the two first limiting portions 250 to elastically move in a direction away from each other until the blood cartridge 300 moves between the two clamping surfaces 251. At this time, the distance between the two first limiting portions 250 no longer changes, and the two first limiting portions 250 clamp the blood cartridge 300.

[0041] Through the above structural arrangement, during the process of storing the blood cartridge 300 in the storage position, the blood cartridge 300 can push open the first limiting portion 250 by abutting against the first guiding surface 252, and then enter between the clamping surfaces 251 of the two first limiting portions 250, so as to be clamped by the two first limiting portions 250. There is no need to additionally provide a power structure to drive the movement of the first limiting portion 250. This not only has a low cost but also is very convenient to operate. Moreover, the two first limiting portions 250 can elastically move and can be applicable to blood cartridges 300 of various specifications.

[0042] It can be understood that in order to make the insertion of the blood cartridge 300 smoother, the clamping surface 251 and the first guiding surface 252 are smoothly transitioned.

[0043] Refer to Figure 7 As shown in the figure, in some embodiments of the present invention, mounting plates 221 are respectively provided on the opposite sides of the two first limiting portions 250 of the carrier plate 220. First guide rods 253 are respectively provided on the opposite sides of the two first limiting portions 250. The first guide rods 253 slidably penetrate through the corresponding mounting plates 221 and are threadedly connected with first limiting nuts 254. By providing the first limiting nuts 254, it is possible to prevent the first guide rods 253 from detaching from the mounting plates 221, and at the same time, the position of the first limiting nuts 254 can be adjusted by screwing to control the movement stroke of the first limiting portions 250. In addition, the first elastic member 270 is provided as a first compression spring and sleeved on the first guide rod 253. The two ends of the first compression spring respectively abut against the first limiting portion 250 and the mounting plate 221 to apply an elastic pressure to the first limiting portion 250. The structure is simple and the installation is convenient. In this embodiment, when the storage position is directly opposite the access port 101, the first guide rods 253 are distributed left and right.

[0044] Based on the above embodiments, it can be conceived that the movement of the second limiting portion 260 can also be realized in the form of electric drive or other power drives. Of course, in order to reduce costs and avoid overly complex control, other non-power drive forms can also be adopted.

[0045] For example, in some embodiments of the present invention, referring to Figures 5 to 8 As shown, the second limiting portion 260 is vertically slidably arranged on the loading tray 220. The limiting assembly further includes a second elastic member 280. The second elastic member 280 is used to apply a downward elastic force to the second limiting portion 260 to press the blood cartridge 300 against the upper surface of the loading tray 220, thereby vertically limiting the blood cartridge 300. The pushing device 240 includes a pushing portion 241, and the pushing portion 241 is configured such that when the storage position where the blood cartridge 300 is placed faces the access port 101, the pushing portion 241 can extend forward and act on the second limiting portion 260 and the blood cartridge 300 in sequence, so as to release the limit of the second limiting portion 260 on the blood cartridge 300 and move the blood cartridge 300 toward the access port 101 in sequence. That is, the release of the limit of the second limiting portion 260 on the blood cartridge 300 and the forward pushing of the blood cartridge 300 are both completed by the pushing portion 241. One device realizes two functions, and the structure is concise.

[0046] Based on the above embodiments, in some embodiments of the present invention, referring to Figure 5 and Figure 8 As shown, the second limiting portion 260 is provided with a second guiding surface 262 at one end of the limiting groove 261 close to the center of the loading tray 220. The second guiding surface 262 extends upward obliquely from the bottom end of the limiting groove 261 toward the center of the loading tray 220. The second guiding surface 262 is used to abut against the pushing portion 241 when the pushing portion 241 extends forward, so that the pushing portion 241 can push the second limiting portion 260 to move upward to release the limit on the blood cartridge 300.

[0047] In this embodiment, by setting the second guiding surface 262, when taking out the blood cartridge 300, after the storage position faces the access port 101, the pushing portion 241 can be made to extend forward. The pushing portion 241 first abuts against the second guiding surface 262, and then under the guidance of the second guiding surface 262, the pushing portion 241 jacks up the second limiting portion 260 upward, so that the second limiting portion 260 releases the limit on the blood cartridge 300. Then the pushing portion 241 continues to move forward until it abuts against the blood cartridge 300, and then the blood cartridge 300 can be pushed forward to the access port 101.

[0048] In a further embodiment, as Figure 10As shown, a first abutting surface 242 and a second abutting surface 243 are provided at the front end of the pushing portion 241. The first abutting surface 242 extends obliquely forward and downward. The first abutting surface 242 is used to abut against the second guiding surface 262 to increase the contact area between the pushing portion 241 and the second limiting portion 260, so that the pushing portion 241 can more smoothly lift the second limiting portion 260. The second abutting surface 243 is located at the inclined bottom end of the first abutting surface 242 and extends vertically. The second abutting surface 243 is used to abut against the blood cartridge 300 to ensure the area between the pushing portion 241 and the blood cartridge 300 and avoid the problem of stress concentration when the pushing portion 241 pushes the blood cartridge 300 forward.

[0049] In a further embodiment, referring to Figure 5 and Figure 8 As shown, a third guiding surface 263 is provided at one end of the limiting groove 261 away from the center of the carrying tray 220 of the second limiting portion 260. The third guiding surface 263 extends obliquely upward from the bottom end of the limiting groove 261 away from the center of the carrying tray 220. The third guiding surface 263 is used to abut against the blood cartridge 300 during the process of the blood cartridge 300 being deposited into the storage position, so as to automatically lift the second limiting portion 260 through the abutment between the blood cartridge 300 and the third guiding surface 263, facilitating the insertion of the blood cartridge 300 into the limiting groove 261.

[0050] Specifically, the two first limiting portions 250 are respectively located on opposite sides of the limiting groove 261. During the process of inserting the blood cartridge 300 from the access opening 101 into the storage position, the blood cartridge 300 first contacts the third guiding surface 263, and the second limiting portion 260 is lifted upward through the guidance of the third guiding surface 263 until the upper end surface of the blood cartridge 300 abuts against the bottom end of the second limiting portion 260 and the second limiting portion 260 no longer moves upward. Then, the blood cartridge 300 is continuously inserted. The blood cartridge 300 first abuts against the first guiding surfaces 252 of the two first limiting portions 250 to push open the two first limiting portions 250 until the blood cartridge 300 moves between the clamping surfaces 251 of the two first limiting portions 250. The distance between the two first limiting portions 250 no longer changes and clamps the blood cartridge 300. Then, the blood cartridge 300 is continuously inserted until the blood cartridge 300 moves to the lower side of the limiting groove 261, and the second limiting portion 260 moves downward under the action of the second elastic member 280 to press the blood cartridge 300, that is, the blood cartridge 300 is stored in the storage position.

[0051] Referring to Figure 7As shown, in some embodiments of the present invention, a bracket 223 is provided on the upper surface of the load tray 220. The bracket 223 is arranged in a portal structure. The second limiting portion 260 is provided with a second guide rod 264 on the upper side of the limiting groove 261. The second guide rod 264 vertically slides through the bracket 223 to slidably mount the second limiting portion 260. A second limiting nut 265 is threadedly connected to the upper side of the bracket 223 on the second guide rod 264 to prevent the second guide rod 264 from separating from the bracket 223. The second elastic member 280 is a second compression spring. The second compression spring is sleeved on the second guide rod 264 and is located on the lower side of the bracket 223. Both ends of the second compression spring respectively abut against the bracket 223 and the second limiting portion 260, thereby applying a downward elastic pressure to the second limiting portion 260. The structure is simple and the installation is convenient.

[0052] It can be conceived that in order to improve the structural stability, multiple second guide rods 264 can be provided.
