[0032] Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. The various technical features of this utility model can be combined interactively without contradicting each other.

[0033] Reference Figure 1 , Figure 2 and Figure 3 This utility model provides a specimen transfer device that facilitates specimen transfer between two or more people, reduces errors and omissions during the transfer process, enables automatic specimen sorting, and improves transfer efficiency.

[0034] In this embodiment, the specimen transfer device includes a placement tray 200, a clamping assembly 300, a camera 100, and a controller. The placement tray 200 has multiple storage areas. For ease of installation, in some embodiments, the specimen transfer device also includes a main frame 100, which is hollow to form an inner cavity, in which the placement tray 200 is disposed.

[0035] Reference Figure 5 The clamping assembly 300 includes a moving drive structure, a mounting base 335, and a gripper 310. The mounting base 335 is disposed in the inner cavity. The camera 100 and the gripper 310 are both connected to the mounting base 335. The moving drive structure is driven to move the mounting base 335. When the moving drive structure drives the mounting base 335 to move in the inner cavity, the camera 100 and the gripper 310 can move simultaneously.

[0036] The camera 100 is positioned facing the gripper 310, which is used to grasp the specimen placed on the placement tray 200. After the gripper 310 grasps the specimen, the camera 100 can take a picture of the specimen grasped by the gripper 310 and obtain the image information of the specimen.

[0037] Understandably, different storage areas are used to hold different specimens. In this embodiment, the specimen is a test tube specimen containing blood. The storage area includes a defective area 220 for placing defective specimens, a qualified area for placing qualified specimens, and a catheter area 230 for placing blood bag catheters. Both the defective area 220 and the qualified area are equipped with test tube racks 210 to facilitate the vertical placement of the test tube specimens.

[0038] Understandably, unqualified test tube specimens include specimens with unidentifiable labels, specimens with insufficient volume, specimens that should have been centrifuged but were not completely centrifuged or lack centrifuge gel, and specimens that were mistakenly centrifuged but did not require centrifugation. These unqualified test tube specimens can all be identified through image information acquired by camera 100. In some embodiments, visual analysis of the blood in the test tube specimen is used. The blood in the test tube has been centrifuged before transfer. The blood in the test tube within the specimen transfer instrument is already in a centrifuged state, with red red blood cells at the bottom and translucent, light-colored plasma at the top. By acquiring image information, the height of the red blood cells in the bottom layer can be determined, thereby obtaining the red blood cell volume of the specimen to distinguish specimens with insufficient volume or those that were not completely centrifuged.

[0039] The camera 100 and the clamping assembly 300 are electrically connected to the controller. The controller is configured to control the moving drive structure to move the mounting base 335 and control the gripper 310 to clamp the classified specimen. After the camera 100 acquires the image information of the specimen, it controls the moving drive structure to drive the gripper 310 to clamp the specimen into the corresponding storage area based on the image information.

[0040] In some embodiments, the caps of different types of test tubes are set to different colors. Based on the color of the cap in the acquired image information, the type of test tube can be analyzed. Then, the clamping component 300 places the different types of test tubes in the corresponding test tube rack 210 according to their categories, thereby realizing the classified placement of test tubes.

[0041] In this embodiment, the specimen transfer device is equipped with an industrial control computer 400, and a controller is located within the industrial control computer 400. The industrial control computer 400 is capable of running software and is mounted on top of the main frame 100. It is understood that the controller can be a microcontroller, PLC controller, etc.

[0042] In some embodiments, the specimen transfer device further includes an automatic door capable of opening or closing the placement tray 200. It is understood that a controller is electrically connected to the automatic door and is capable of controlling the opening or closing of the automatic door.

[0043] The automatic door can protect the specimen on the placement tray 200 and provide a relatively enclosed space for the specimen, reducing the impact of the external environment on the specimen.

[0044] In some embodiments, the specimen transfer device further includes an identity reader electrically connected to the controller. The identity reader is used to identify the user, and when the identity reader detects that the user has the authority to open the door, the controller controls the automatic door to open automatically.

[0045] This setup allows for the verification of the identity information of the person handing over the specimen, matching the identity information of the person handing over the specimen with the specimen, which is more conducive to the subsequent traceability of the specimen.

[0046] Identity recognition devices can be keypads, facial recognition devices, card readers, etc., and can identify users through password input recognition, facial recognition, card swiping recognition, etc.

[0047] In some embodiments, the specimen transfer device further includes a barcode scanning component electrically connected to the controller. The barcode scanning component scans the document code on the transfer slip corresponding to the specimen. It is understood that each batch of specimens is accompanied by a transfer slip, which can be electronic or paper. The document code can be a barcode or QR code on the transfer slip. The blood bank's database records the specimen data for the batch corresponding to the document code. By scanning the document code on the transfer slip, the industrial control computer 400 can export the specimen data for the batch corresponding to the document code from the blood bank's database. After the barcode scanning component identifies the document code on the transfer slip, the industrial control computer 400 can retrieve the specimen data for the corresponding batch from the blood bank's database, including but not limited to the specimen quantity and the identity information of the transferee. This specimen data can be displayed on the specimen transfer device's display structure or transmitted to the transferee's mobile device, such as a mobile phone, to facilitate verification and further improve the reliability of the transfer.

[0048] In some embodiments, refer to Figure 5 The clamping assembly 300 also includes a rotary drive structure 350, which is connected to the mounting base 335 and driven by the gripper 310. Under the driving action of the rotary drive structure 350, the gripper 310 can rotate relative to the camera 100 so that the camera 100 can acquire 360° information of the specimen and improve the accuracy of classification.

[0049] Understandably, the rotary drive structure 350 is electrically connected to the controller, which can control the rotary drive component to start, thereby controlling the gripper 310 to grasp the specimen and slowly rotate it in front of the camera 100. The camera 100 quickly captures images of the specimen's outer periphery, obtaining comprehensive information about the specimen. With this setup, there is no need to pay attention to the label's orientation when placing the specimen; even if the label's initial position on the specimen is not aligned with the camera 100, the label can still be captured during the specimen's rotation.

[0050] In some embodiments, the moving drive structure includes a lifting component 320 and a left-right driving component 330. The output end of the lifting component 320 is connected to the left-right driving component 330, and the output end of the left-right driving component 330 is driven to the mounting base 335. The specimen transfer instrument also includes a front-rear driving component 600, which is installed in the inner cavity and driven to the placement tray 200 or the lifting component 320. Under the driving action of the lifting component 320, the left-right driving component 330 can move in the vertical direction. Under the driving action of the left-right driving component 330, the mounting base 335 and the gripper 310 and camera 100 connected thereto can move in the horizontal direction. Under the driving action of the front-rear driving component 600, the placement tray 200 or the lifting component 320 can move in the front-back direction. Through the combined action of the lifting component 320, the left-right driving component 330, and the front-rear driving component 600, the gripper 310 can move in all directions relative to the placement tray 200 to facilitate the gripping and placement of specimens.

[0051] In this embodiment, the output end of the front and rear drive component 600 is connected to the placement disk 200. By driving the placement disk 200 to move back and forth, the gripper 310 and the placement disk 200 can move in the front and rear direction.

[0052] In some embodiments, the placement tray 200 has multiple layers arranged vertically. This arrangement allows for the placement of more specimens within the cavity, facilitating the transfer of larger batches of specimens. Each front-to-back drive component 600 corresponds to one of the placement trays 200 and is electrically connected to a controller. When a specimen needs to be picked up from one of the placement trays 200, the corresponding front-to-back drive component 600 is activated, causing the tray 200 to move relative to the other trays 200 in the front-to-back direction. This ensures that there is no obstruction between the specimen on the tray 200 and the gripper 310, allowing the gripper 310 to pick up the specimen.

[0053] In this embodiment, refer to Figure 4 The lifting component 320 includes a lifting drive source, a counterweight 321, a first synchronous belt 322, and a drive shaft 323. The drive shaft 323 extends in a left-right direction. Two first synchronous belts 322 are provided, and the two first synchronous belts 322 are respectively sleeved on the left and right ends of the drive shaft 323. The two ends of each first synchronous belt 322 are connected to the counterweight 321 and the left and right drive components 330, respectively. That is, the left and right ends of the counterweight 321 are connected to the two first synchronous belts 322, and the left and right ends of the left and right drive components 330 are connected to the two first synchronous belts 322, respectively. The counterweight 321 is located on the rear side of the drive shaft 323, and the left and right drive components 330 are located on the front side of the drive shaft 323.

[0054] The output end of the lifting drive source is connected to the drive shaft 323. Under the driving action of the lifting drive source, the drive shaft 323 rotates around its own central axis and drives the first synchronous belt 322 to move, so that the left and right drive components 330 can achieve lifting action.

[0055] It is understandable that the drive shaft 323 has a first synchronous pulley at each of its left and right ends, and two first synchronous belts 322 are respectively fitted on the outside of the two first synchronous pulleys. When the drive shaft 323 rotates, the first synchronous belts 322 move synchronously with the first synchronous pulleys.

[0056] Understandably, the counterweight 321 can counteract the weight of the left and right drive components 330, the mounting base 335, the gripper 310, and the camera 100, reducing the risk of the left and right drive components 330 malfunctioning and falling.

[0057] In some embodiments, the lifting component 320 further includes a bracket for mounting structures such as a lifting drive source, which may be made of aluminum profiles, steel, etc.

[0058] In this embodiment, the lifting drive source includes a first motor 324, a second synchronous belt 325, and two second synchronous pulleys 326. One second synchronous pulley 326 is mounted on the output end of the first motor 324, and another second synchronous pulley 326 is mounted on either the left or right end of the drive shaft 323. The second synchronous belt 325 is sleeved on the outside of the two second synchronous pulleys 326. When the first motor 324 operates, the second synchronous pulley 326 connected to the output end of the first motor 324 rotates, driving the second synchronous belt 325 to rotate, thus rotating the second synchronous pulley 326 mounted on the drive shaft 323, thereby driving the drive shaft 323. The transmission of power from the second synchronous belt 325 to the second synchronous pulleys 326 to the first motor 324 ensures the normal operation of the drive shaft 323 and reduces the risk of failure.

[0059] In some embodiments, the lifting component 320 further includes two first guide rails 327 and two second guide rails 328, which are mounted on a bracket and extend vertically. The left and right ends of the left and right driving component 330 are slidably connected to the two first guide rails 327, and the left and right ends of the counterweight 321 are slidably connected to the two second guide rails 328.

[0060] Specifically, the left and right drive components 330 are provided with first sliding grooves at both ends, with openings at the top and bottom, and a first guide rail 327 is engaged with the first sliding groove. The counterweight block 321 is provided with second sliding grooves at both ends, with openings at the top and bottom, and a second guide rail 328 is engaged with the second sliding groove.

[0061] Understandably, the first guide rail 327 is configured to constrain the left and right drive components 330 from moving vertically under the drive of the lifting drive source. The second guide rail 328 is configured to constrain the counterweight 321 from moving vertically under the drive of the lifting drive source.

[0062] In some embodiments, refer to Figure 5 The left and right drive components 330 include a mounting bracket 331, a second motor 332, a third synchronous belt 333, and a third synchronous pulley 334. The mounting bracket 331 provides a mounting position for the second motor 332 and the third synchronous pulley 334. The body of the second motor 332 is mounted on the left or right end of the mounting bracket 331. Two third synchronous pulleys 334 are provided; one is mounted on the output end of the second motor 332, and the other is rotatably connected to the right or left end of the mounting bracket 331, meaning the two pulleys 334 are located at the left and right ends of the mounting bracket 331, respectively. The third synchronous belt 333 is fitted over the outside of the two pulleys 334. When the second motor 332 starts, the third synchronous pulley 334 connected to the second motor 332 rotates, causing the third synchronous belt 333 to move accordingly, and the other pulley 334 also rotates.

[0063] It is understood that the rotary drive structure 350 is mounted on the mounting base 335, which is connected to the third synchronous belt 333 and located between the two third synchronous pulleys 334. When the third synchronous belt 333 moves, the mounting base 335 can move in the left and right direction, thereby enabling the camera 100, the rotary drive structure 350 and the gripper 310 connected thereto to move in the left and right direction.

[0064] In some embodiments, the left and right drive component 330 further includes a third guide rail 336, which extends in the left and right direction and is disposed on the mounting bracket 331. A third sliding groove is provided at the lower end of the mounting base 335, and the third sliding groove engages with the third guide rail 336. When the mounting base 335 moves in the left and right direction, the groove wall of the third sliding groove moves relative to the third guide rail 336. It is understood that the third guide rail 336 can constrain the movement of the mounting base 335 in the left and right direction, preventing the mounting base 335 from shifting, thereby improving the accuracy of the gripper 310 in grasping the specimen.

[0065] In this embodiment, the first slide groove is located on the rear side of the mounting frame 331, and the first synchronous belt 322 is connected to the mounting frame 331.

[0066] In some embodiments, the moving drive structure further includes a vertical drive component 340, which is mounted on the mounting base 335 and has its output end connected to the gripper 310. Under the driving action of the vertical drive component 340, the gripper 310 can move relative to the mounting base 335 in the vertical direction.

[0067] Understandably, for test tube specimens placed on the test tube rack 210, the gripper 310 needs to be driven up and down by the up and down drive component 340. After the gripper 310 picks up the specimen, it moves up a certain distance to let the test tube specimen leave the test tube rack 210 and move the test tube specimen to a height that is convenient for the camera 100 to obtain image information, so as to ensure the accuracy of the gripping and shooting actions.

[0068] In some embodiments, the up-down driving component 340 further includes a third motor and a transmission component. The transmission component is connected to the output end of the third motor and the body of the rotary driving structure 350, respectively. Under the driving action of the third motor, the rotary driving structure 350 and the gripper 310 connected thereto can move a distance in the up-down direction so that the gripper 310 can take the test tubes off or put them down from the test tube rack 210.

[0069] It is understandable that the rotary drive structure 350 can be a stepper motor, etc.

[0070] In this embodiment, refer to Figure 6 The front and rear drive components 600 include a fourth motor 610, a fourth guide rail 630, a lead screw 620, a slider 640, a fourth synchronous belt 650, and a fourth synchronous pulley 660. Two fourth synchronous pulleys 660 are provided; one is mounted at the output end of the fourth motor 610, and the other is mounted at the rear end of the lead screw 620. The lead screw 620 extends in the front-rear direction, and the fourth synchronous belt 650 is sleeved on the outside of the two fourth synchronous pulleys 660. When the fourth motor 610 starts, its power is transmitted to the lead screw 620 through the fourth synchronous pulleys 660 and the fourth synchronous belt 650, allowing the lead screw 620 to rotate around its central axis.

[0071] The slider 640 has a threaded hole, and the lead screw 620 passes through the threaded hole and is threadedly connected to it. The slider 640 is connected to the placement tray 200, which has a fourth sliding groove. Both ends of the fourth sliding groove are open, and a fourth guide rail 630 extends in the front-back direction. The fourth sliding groove is engaged with the fourth guide rail 630. In this embodiment, two fourth guide rails 630 are provided, located at the left and right ends of the placement tray 200 respectively. The placement tray 200 has two fourth sliding grooves. When the lead screw 620 rotates, due to the restraining effect of the fourth guide rails 630 and the fourth sliding grooves, the slider 640 and the placement tray 200 can move along the extension direction of the lead screw 620, i.e., in the front-back direction.

[0072] Understandably, the two fourth guide rails 630 are connected to the walls of the inner cavity, and the body of the fourth motor 610 is also mounted on the walls of the inner cavity.

[0073] In some embodiments, the specimen transfer device further includes an operation panel 500, which is electrically connected to the controller. The operation panel 500 is used to realize human-machine interaction. The transfer personnel can use the operation panel 500 to control the industrial control computer 400 to turn on or off, etc., by means of touch, buttons, etc. The operation panel 500 can also serve as a display structure to display specimen information, so as to facilitate the transfer personnel to perform verification and other operations, further improving the accuracy of specimen transfer.

[0074] In some embodiments, the operation screen 500 is connected to the main frame 100 and is located on the front side of the main frame 100 for easier user operation. Of course, the operation screen 500 can also be located on the left, right, or rear side of the main frame 100, depending on actual needs; no specific limitation is made here. In other embodiments, the operation screen 500 and the main frame 100 are set independently of each other.

[0075] In this embodiment, the operation screen 500 is a touch screen, and the user achieves human-computer interaction through touch.

[0076] In some embodiments, the specimen transfer instrument further includes a cooling component electrically connected to a controller. When the temperature of the inner cavity is higher than a preset temperature, the controller activates the cooling component to lower the temperature of the inner cavity. In this embodiment, the cooling component maintains the inner cavity within a temperature range of greater than or equal to 1°C and less than or equal to 6°C to ensure that the specimen quality is not affected after the specimen is left in the specimen transfer instrument overnight or for a long period of time.

[0077] In some embodiments, the refrigeration component includes a compressor, a condenser, an expansion valve, and an evaporator, which are connected in sequence by pipes to form a closed system in which the refrigerant circulates. It is understood that the refrigeration component is a conventional structure in the art, and those skilled in the art should be familiar with its construction and principles.

[0078] In some embodiments, casters are installed at the bottom of the main frame 100 to facilitate the user's movement of the specimen transfer instrument.

[0079] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
