[0027] At present, for the detection of samples in the laboratory, it is often necessary to manually unpack the samples and draw the samples. However, since the entire process is manual, there are not only problems of contamination or drawing the wrong samples, but also the personnel are prone to scratching themselves in the process of unpacking, which is less safe. Specifically, since the operation of drawing the sample is single and requires a long time to repeat, personnel are prone to drawing the wrong samples during repeated operations, and deviations are prone to occur in the operation during the drawing operation, resulting in inaccurate results of the final inspection. When drawing the sample, personnel are also required to manually enter the sample information in sequence before testing. There are cases of input errors during the repeated operation, which affects the subsequent sample tracing. Therefore, how to realize the automation of sample drawing, avoid external contamination caused by contamination during the transfer process, avoid sample drawing errors, and scan code record errors, so as to reduce the risk of excessive deviation in the project test results is a problem that people in this field need to solve.

[0028] The technical solution of this embodiment will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0029] like Figure 1-Figure 4As shown, this embodiment provides a fully automatic sample suction device, including a workbench 10, and an opening component 20, a first carrier plate 30, a barcode scanner 40, a sample suction component and a second carrier plate 70 arranged on the workbench 10. The unopened sample is placed in the first carrier plate 30, and the opening component 20 can unpack the sample. The barcode scanner 40 is spaced apart from the first carrier plate 30 and can scan and record the unpacked sample. The sample suction component is adjustably arranged on the workbench 10, and can aspirate the scanned sample and then transport it to the test tube 701 in the second carrier plate 70.

[0030] Specifically, in this embodiment, the first carrier plate 30 can ensure the stable placement of the sample, and the unpacking component 20 can be used to mechanically unpack the sample, effectively avoiding the safety hazards of manual unpacking in the prior art. Furthermore, the code scanner 40 is used to automatically scan the unpacked sample, and then the sample suction component is used to aspirate the sample, which can effectively avoid the erroneous operation or forgetfulness of manual scanning and recording. The position of the sample suction component is adjustable on the workbench 10, and it can aspirate the scanned sample and transfer it to the test tube 701 in the second carrier plate 70, which can effectively realize the automation of the sample suction operation, avoid errors or external contamination during the transfer process, thereby improving the detection efficiency of the sample and ensuring the accuracy of the final test results.

[0031] The specific structure of the fully automatic sample aspirating device in this embodiment is described below.

[0032] like Figure 1 and Figure 2As shown, the fully automatic sample aspirating device in this embodiment includes a workbench 10, a package opening assembly 20, a first carrier plate 30, a barcode scanner 40, a sample aspirating assembly, a tip box 60, a second carrier plate 70, and a waste bucket 80, and a protective cover 100 is provided above the workbench 10. Optionally, in this embodiment, the package opening assembly 20, the first carrier plate 30, the barcode scanner 40, the sample aspirating assembly, the tip box 60, the second carrier plate 70, and the waste bucket 80 are all arranged on the workbench 10, and the package opening assembly 20, the first carrier plate 30, the barcode scanner 40, the tip box 60, the waste bucket 80, and the second carrier plate 70 are arranged in sequence from left to right, and the sample aspirating assembly is adjustable on the workbench 10 to facilitate sample aspiration, installation and disposal of tips. Specifically, unopened samples are placed on the first carrier tray 30, and the package opening assembly 20 can open the samples. Then, the barcode scanner 40, located spaced apart from the package opening assembly 20, can scan and record the opened samples, making the sampling process traceable. Furthermore, the sampling assembly can install pipette tips in the tip box 60, move to the first carrier tray 30, aspirate the scanned samples, and transfer them to the test tube 701 on the second carrier tray 70, completing the sample aspiration operation. The assembly then moves back to the waste bin 80 to discard the used pipette tips and wait for the next sampling operation, thereby effectively preventing cross-contamination between samples.

[0033] Specifically, a control system 101 is provided on the workbench 10, and the control system 101 can control the opening and closing of the package opening component 20 and the sample suction component, thereby realizing the automation of the entire sample suction process and avoiding the manual sample suction operation in the prior art. Furthermore, the movement between different stations of the sample suction component can also be controlled by the control system 101 to improve the working efficiency. For example, the control system 101 can be connected to the control software through other communication methods such as Bluetooth, so as to control the movement and opening and closing of the package opening component 20 and the sample suction component. Figure 2 As shown, a protective cover 100 is provided above the workbench 10 , which can effectively prevent external interference or contamination during the entire sample aspiration process, thereby improving the safety and accuracy of the sample aspiration.

[0034] Combine Figure 1 and Figure 2As shown, in this embodiment, the package opening assembly 20 includes a support frame 21, a disinfectant barrel 22, an atomizer 23, a first telescopic rod, and a cutter head 24. Specifically, the support frame 21 is vertically arranged on the workbench 10, and the disinfectant barrel 22 is fixed to the top of the support frame 21. Optionally, the disinfectant barrel 22 is used to store disinfectant. Furthermore, the disinfectant barrel 22 is connected to the atomizer 23, which is arranged below the disinfectant barrel 22 and is sleeved on the outside of the first telescopic rod. One end of the first telescopic rod is fixed to the support frame 21, and the other end is configured as a telescopic end. The cutter head 24 is mounted on the telescopic end, so that the cutter head 24 can move closer to or away from the sample under the action of the first telescopic rod. For example, the atomizer 23 can atomize the disinfectant in the disinfectant barrel 22 and spray it onto the cutter head 24 during the package opening process. As a result, the cutter head 24 can be disinfected in real time during the package opening operation, thereby meeting the requirements for aseptic operation of microbial samples. Furthermore, the cutter head 24 is configured as a spiral cutter head and is rotatable relative to the first telescopic rod. In this embodiment, the control system 101 is used to control the vertical extension and retraction of the first telescopic rod and the rotation of the cutter head 24, thereby achieving automated package opening. For example, a protective cover is provided on the outside of the cutter head 24 to prevent injuries during rotation.

[0035] Combine Figure 1-Figure 4 As shown, in this embodiment, a number of fixed holes 301 are provided on the first carrier plate 30, and an elastic gripper 302 is provided in each fixed hole 301. Optionally, the sample can be inserted into the fixed hole 301 and can be pressed against the outside of the sample by the elastic gripper 302 to ensure the stable placement of the sample. For example, in this embodiment, the first carrier plate 30 is configured as a circular plate, and 23 fixed holes 301 are provided on it, which can be arranged as needed in other embodiments. Furthermore, in this embodiment, the first carrier plate 30 can be rotated by the drive of a motor, so that the sample can be transferred to the bottom of the cutter head 24 for unpacking, and then transferred to the barcode scanner 40 for scanning, until it is sucked and processed by the sample suction component. Specifically, when placing the sample, the unique code of the sample needs to be placed outward to facilitate scanning by the barcode scanner 40.

[0036] For example, in this embodiment, the rear elastic gripper 302 is made of an elastic member and forms a tic-tac-toe structure in the fixing hole 301, so that after the sample is inserted into the fixing hole 301, it can be stably fixed in the center and can be applied to samples of different specifications, thereby expanding the scope of application of the first carrier plate 30. Figure 1 As shown, in this embodiment, the code scanner 40 is spaced apart from the first carrier plate 30 , and the height of the code scanner 40 is adapted to the coding height of the sample, thereby ensuring the effective scanning range of the code scanner 40 .

[0037] Combine Figure 1-Figure 3As shown, in this embodiment, the sample suction assembly includes a drive motor 51, a slide rail 52, a second telescopic rod 53 and a sample suction device 54, and a bracket 521 is slidably provided on the slide rail 52. Optionally, in this embodiment, the drive motor 51 is vertically arranged on the workbench 10, and the slide rail 52 is horizontally mounted on the top of the drive motor 51, and the length of the slide rail 52 is at least greater than the distance between the first carrier plate 30 and the second carrier plate 70, so that movement between different workstations can be achieved. Exemplarily, the bracket 521 is arranged perpendicular to the slide rail 52, and one end of the bracket 521 is slidably provided in the slide rail 52, and the other end is connected to the second telescopic rod 53, and the sample suction device 54 is installed at the telescopic end of the second telescopic rod 53, so that it can approach or move away from the sample or test tube 701 under the action of the second telescopic rod 53 to achieve corresponding sample suction transfer and other operations.

[0038] Specifically, in this embodiment, the drive motor 51 can drive the bracket 521 to move between the stations on the slide 52, and can control the up and down movement of the second telescopic rod 53, as well as the suction of the sampler 54 and the discarding of the tips. For example, the slide 52 is provided with at least an installation station, a sample suction station, a liquid discharge station and a discard station. Specifically, when in the installation station, the sampler 54 is located at the tip box 60, so that the tips can be installed; when in the sample suction station, the sampler 54 is located at the first carrier plate 30, so that the scanned samples can be aspirated; when in the liquid discharge station, the sampler 54 is located at the second carrier plate 70, so that the sample can be discharged into the test tube 701; when in the discard station, the sampler 54 is located at the waste bucket 80, so that the used tips can be discarded in the waste bucket 80, which is convenient for unified processing and effectively ensures that only one type of tip is used for each sample suction, avoiding cross-infection between samples. For example, the drive motor 51 may also be controlled by the control system 101 to achieve automated operation.

[0039] Optionally, in this embodiment, a number of tips are placed on the tip box 60, and the tip box 60 is arranged between the barcode scanner 40 and the second carrier plate 70, and the sample aspirator 54 in the sample aspirating assembly can be moved to the tip box 60 to install the tips. For example, the tips can be set as disposable tips, so as to reduce the operating costs while ensuring the one-to-one correspondence between samples and tips, thereby avoiding cross-infection between samples. Furthermore, a limiting protrusion is provided on the workbench 10, and a limiting groove is provided at the bottom of the tip box 60, and the limiting protrusion can be inserted into the limiting groove, thereby ensuring that the tip box 60 is stably placed on the workbench 10, and the position displacement will not occur during the installation of the tips by the sample aspirator 54, and it is convenient for the operator to replenish the tips on the tip box 60 in a timely manner. Furthermore, the waste bucket 80 is arranged between the tip box 60 and the second carrying plate 70, mainly for collecting discarded tips, and the waste bucket 80 can also be fixed on the workbench 10 by means of limiting protrusions and limiting grooves, which will not be described in detail here.

[0040] Combine Figure 1 and Figure 3 As shown, in this embodiment, the second carrier plate 70 is also provided with a plurality of receiving grooves, and the test tube 701 is placed in the receiving grooves. For example, in this embodiment, the receiving grooves are arranged in a one-to-one correspondence with the fixed hole 301, and the second carrier plate 70 is also configured as a circular disk, which can also rotate on the workbench 10 under the drive of the motor, thereby improving the efficiency of the sample aspirator 54 in discharging liquid. For example, the second carrier plate 70 is also provided with 23 receiving grooves, and the second carrier plate 70 and the first carrier plate 30 can rotate synchronously under the drive of the motor to ensure the accuracy of the discharging position. Optionally, markings can be made on the first carrier plate 30 and the second carrier plate 70 to ensure that the positions of the sample aspirator and the discharging are consistent, avoiding the problem of sample mixing when the operator takes the test tube 701. For example, elastic members can also be placed in the receiving grooves to ensure the stable placement of the test tube 701, and the motors driving the first carrier plate 30 and the second carrier plate 70 can also be controlled by the control system 101 to achieve automated operation.

[0041] Working process: the control system 101 drives the unpacking component 20 to unpack the sample; then the first carrier plate 30 is rotated to rotate the unpacked sample to the side of the barcode scanner 40 for scanning and recording; then the sample aspirator 54 is driven to move to the installation station to install the suction head, and then moved to the suction station to aspirate the scanned sample; then the sample aspirator 54 is driven to move to the liquid discharge station at the second carrier plate 70, and the aspirated sample is discharged into the corresponding test tube 701 to complete the suction work; finally, the sample aspirator 54 moves to the discard station and discards the used suction head into the waste bucket 80 to wait for the next suction operation.

[0042] In this embodiment, only one sample aspirator 54 is used to repeatedly install disposable tips, ensuring that a new tip is replaced for each sample wine, thereby effectively preventing cross-contamination between samples. Furthermore, in this embodiment, the disinfectant barrel 22 and atomizer 23 are used to disinfect the blade 24 in real time, thereby preventing problems such as microbial infection. The barcode scanner 40 ensures that each sampling process is traceable. Under the protection of the protective cover 100, the entire sampling process is effectively safe and controllable, with high automation efficiency.

[0043] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation methods here.
