Description

Technical Field

[0001] This application relates to the technical field of medical devices, and particularly to a sample analysis system. Background Art

[0002] For a traditional fully automatic chemiluminescence immunoassay system, if a sample needs to be reexamined, the carrier takes out the sample to be reexamined from the buffer position, sends the sample to the inner track, the sample needle aspirates the sample and then adds it to the reaction disk. The sample transportation path is long and the time consumption is long. When encountering an emergency sample, the emergency sample needs to be transmitted through the outer track, and then the emergency sample is taken and placed on the inner track by the gripper, and then transmitted to the vicinity of the sample needle by the inner track again. The sample needle aspirates the sample and then adds it to the reaction disk, which is time-consuming and laborious. Moreover, other samples on the outer track and the inner track need to take avoidance actions, resulting in affecting the overall sample detection progress and lengthening the overall detection cycle.

[0025] In view of the above problems, an embodiment of the present application provides a sample analysis system, which can shorten the sample transportation path and save the time for submitting samples for inspection.

[0026] The technical solutions of the embodiments of the present application will be described in detail below with reference to the drawings.

[0027] Figure 1 It is a schematic structural diagram of the sample analysis system shown in the embodiment of the present application.

[0028] See Figure 1 , the sample analysis system includes a sample injection area (not shown), a detection area 1, a main conveying mechanism 2, a buffer mechanism 3, a conventional detection channel and an emergency re-inspection channel. The emergency re-inspection channel can send the sample to the detection area 1 instead of the conventional detection channel.

[0029] See Figure 1 , the detection area 1 is used for detecting samples. The detection area 1 is provided with a reaction plate 11, a reagent plate 12, a general liquid plate 13, a plurality of sampling needles 14, a conventional detection position and an emergency detection position. Among them, the sampling needle 14 can move between the reaction plate 11, the reagent plate 12 and the general liquid plate 13. The sampling needle 14 can suck reagents from the reagent plate 12 or the general liquid plate 13 and inject them into the reaction plate 11. The sampling needle 14 can also suck the sample on the main conveying mechanism 2 and then add the sample liquid to the reaction plate 11. The conventional detection position and the emergency detection position are located on the reaction plate 11. The reaction plate 11 can adjust the positions of the conventional detection position or the emergency detection position by rotation, so that the sampling needle 14 can add the sample to the conventional detection position or the emergency detection position. The conventional detection position can be one, two or more, and the emergency detection position can be one, two or more.

[0030] See Figure 1 Figure 1 , the main conveying mechanism 2 runs through the sampling area (not shown), the buffer mechanism 3, and the detection area 1. The main conveying mechanism 2 is used to receive the samples to be detected input from the sampling area (not shown), convey the samples to the buffer mechanism 3, send the samples to the detection area 1, or output the detected samples. Specifically, the main conveying mechanism 2 can receive new samples from the sampling area (not shown); the main conveying mechanism 2 can transport the new samples to the detection area 1 for the detection area 1 to detect the new samples; the main conveying mechanism 2 can transport the samples detected by the detection area 1 to the buffer mechanism 3, or directly convey the new samples to the buffer mechanism 3 without being detected by the detection area 1; the main conveying mechanism 2 can transport the samples in the buffer mechanism 3 to the detection area 1 for detection, or output the samples in the buffer mechanism 3 to external devices; the main conveying mechanism 2 can output the samples detected by the detection area 1 to external devices.

[0031] See Figure 1 Figure 1 , the buffer mechanism 3 is located on one side of the sampling area (not shown). The buffer mechanism 3 is used to store samples. The buffer mechanism 3 can place samples to be rechecked. If the detection results of some samples are abnormal when they are first detected by the detection area 1, the samples can be moved to the buffer mechanism 3 by the main conveying mechanism 2 for buffering and waiting for the next detection. In addition, when multiple samples need to be detected, the samples can be sent to the buffer mechanism 3 by the main conveying mechanism 2 for storage, and when it is the turn of the corresponding samples to be detected, they are taken out from the buffer mechanism 3 and sent to the detection area 1 to avoid congestion of the samples during transportation. The buffer mechanism 3 has multiple slots, and the slots can hold sample racks, and the sample racks can hold multiple samples.

[0032] See Figure 1 Figure 1 , the sampling area (not shown), the main conveying mechanism 2, and the conventional detection position are sequentially arranged on the conventional detection channel, and the samples to be detected are sent to the conventional detection position through the conventional detection channel for detection; the buffer mechanism 3 and the emergency detection position are arranged on the emergency recheck channel, and the samples to be detected are sent to the emergency detection position through the emergency recheck channel for detection.

[0033] In this application, by setting up an emergency recheck channel, if the samples on the buffer mechanism 3 need to be rechecked, the samples to be detected can enter the emergency recheck channel from the buffer mechanism 3, reach the emergency detection position through the emergency recheck channel, and the samples to be detected are detected at the emergency detection position, avoiding transporting the samples through the conventional detection channel, preventing conflicts between the travel of the samples during recheck and the conventional detection channel, and the sample transportation path is short, saving the sample submission time and improving the sample detection efficiency.

[0034] See Figure 1, the sample analysis system further includes a handling mechanism 5. The handling mechanism 5 can be a robotic arm or a handling cart. The handling mechanism 5 moves between the main conveying mechanism 2 and the buffer mechanism 3. The handling mechanism 5 can convey the samples on the main conveying mechanism 2 to the buffer mechanism 3, or convey the samples on the buffer mechanism 3 to the main conveying mechanism 2, so that the samples enter the conventional detection channel. The handling mechanism 5 can convey the samples on the buffer mechanism 3 into the emergency re-inspection channel. The sample analysis system further includes a sample submission mechanism 4. The sample submission mechanism 4 is arranged on the emergency re-inspection channel. The sample submission mechanism 4 is located between the detection area 1 and the buffer mechanism 3. The sample submission mechanism 4 is used to send the samples to the detection area 1. When the main conveying mechanism 2 receives new samples from external devices or conveys samples to external devices, the buffer mechanism 3 can convey samples to the sample submission mechanism 4 through the handling mechanism 5. The sample submission mechanism 4 can convey the samples to the detection area 1 for detection. Specifically, the sample submission mechanism 4 can convey the samples to the emergency detection position. Among them, the sample submission mechanism 4 and the main conveying mechanism 2 do not interfere with each other, and the main conveying mechanism 2 does not need to make concessions for sample submission.

[0035] In some embodiments, the handling mechanism 5 can also move between the buffer mechanism 3 and the sample submission mechanism 4. The sample submission mechanism 4 can be a robotic arm. The robotic arm grabs samples on the buffer mechanism 3 and transfers them to the detection area 1. The sampling needle 14 in the detection area 1 then samples the samples and transfers them to the reaction disc 11.

[0036] Figure 2 is a schematic plan view of the sample analysis system shown in the embodiments of the present application.

[0037] See Figure 1 and Figure 2 , in some embodiments, the sample submission mechanism 4 includes a sample addition mechanism 41 and a sample addition position 42. The sample addition mechanism 41 is located on the side of the detection area 1 close to the buffer mechanism 3. The sample addition position 42 is used to place the samples transferred from the buffer mechanism 3. The buffer mechanism 3 conveys samples to the sample addition position 42 through the handling mechanism 5. The sample addition mechanism 41 is used to suck the samples on the sample addition position 42 and transfer them to the emergency detection position. By setting the sample addition position 42 independent of the main conveying mechanism 2, it is possible to avoid conflicts in the travel between the sample addition position 42 and the main conveying mechanism 2, thereby improving the sampling and detection efficiency of the detection area 1 for samples. The sample addition mechanism 41 includes a sample addition needle and a rotating arm. The rotating arm is connected to the sample addition needle. The rotating arm can drive the sample addition needle to move in an arc. The sample addition position 42 and the detection area 1 are within the arc movement range of the sample addition needle. The sample addition needle can move above the sample addition position 42 or the detection area 1. The rotating arm can also drive the sample addition needle to move up and down, so that when the sample addition needle is above the sample addition position 42 or the detection area 1, it can descend into the sample to sample or add samples. Specifically, the sample addition needle can suck the sample liquid from the samples on the sample addition position 42 and then inject the sample liquid into the detection area 1.

[0038] The sample loading position 42 is provided with a transportation device for pushing the sample to move. Since the sample is usually placed on a sample rack, and multiple samples are generally placed on the sample rack, the rotating arm drives the sampling needle to move in an arc. To ensure that the sampling needle can sample all the samples on the sample rack, the transportation device is used to push the sample to move, so that all the samples on the sample rack can be at the tangent points of the movement trajectory of the sampling needle, ensuring that the sampling needle can aspirate all the samples.

[0039] Figure 3 It is a schematic structural diagram of the emergency position shown in the embodiment of the present application.

[0040] See Figures 1-3 , the sample analysis system further includes an emergency detection loading position 6. The emergency detection loading position 6 is located on the side of the buffer mechanism 3 away from the main conveying mechanism 2. The emergency detection loading position 6 is used to receive the sample rack or the quality control rack, and the emergency detection loading position 6 conveys the sample rack to the emergency detection position through the emergency re-inspection channel. Specifically, the staff can place the emergency samples to be detected in the sample rack, and then place the sample rack with the emergency samples on the emergency detection loading position 6. The handling mechanism 5 can carry the sample rack at the emergency detection loading position 6 to the sample loading position 42. The sampling needle then aspirates the sample liquid from the sample on the sample loading position 42 and transfers the sample liquid to the emergency detection position.

[0041] See Figures 1-3 , in some embodiments, the buffer mechanism 3 is provided with a number of buffer positions, and each buffer position can place a sample rack or a sample. The emergency detection loading position 6 is arranged side by side with the buffer positions, and the emergency detection loading position 6 is located on the side of the handling mechanism 5 facing away from the detection area 1. When the handling mechanism 5 is a handling vehicle, since the emergency detection loading position 6 is arranged side by side with the buffer positions, the handling mechanism 5 can rely on linear driving to realize the switching of the docking positions of the emergency detection loading position 6 and the buffer positions, reducing the driving distance of the handling mechanism 5 and improving the work efficiency; the emergency detection loading position 6 is located on the side of the handling mechanism 5 facing away from the detection area 1, and the handling mechanism 5 can use the same method to pull the sample on the buffer position or the sample on the emergency detection loading position 6 onto the handling mechanism 5, thereby simplifying the operation of the handling mechanism 5.

[0042] See Figures 1-3, the sample analysis system further includes an identification mechanism 7 for identifying the emergency detection loading position 6. On one side of the detection area 1 close to the buffer mechanism 3, there is a quality control area 8. When a quality control rack is placed at the emergency detection loading position 6, the emergency detection loading position 6 conveys the quality control rack to the quality control area 8 through the handling mechanism 5. Specifically, the identification mechanism 7 can be a camera or a barcode scanner. When the identification mechanism 7 is a camera, image recognition can be performed on the object at the emergency detection loading position 6 through the camera. If the object at the emergency detection loading position 6 is a quality control rack, the handling mechanism 5 pulls the quality control rack onto the handling mechanism 5 and then transports the quality control rack to the quality control area 8 for storage; if the object at the emergency detection loading position 6 is a sample rack, the handling mechanism 5 pulls the sample rack onto the handling mechanism 5 and then transports the sample rack to the sample submission mechanism 4. When the identification mechanism 7 is a barcode scanner, different barcodes or QR codes can be set on the quality control rack and the sample rack respectively, and the barcode or QR code is scanned by the barcode scanner to determine whether the object at the emergency detection loading position 6 is a sample rack or a quality control rack, and then the object at the emergency detection loading position 6 is transported to the corresponding position through the handling mechanism 5.

[0043] See Figure 1 and Figure 2 , the main conveying mechanism 2 includes an outer rail sample inlet rail 21, an outer rail return rail 22, an inner rail sample inlet rail 23, an inner rail return rail 24 and a gripper 25. The gripper 25 is used to handle samples, and samples are transferred between the outer rail sample inlet rail 21, the outer rail return rail 22, the inner rail sample inlet rail 23 and the inner rail return rail 24 through the gripper 25. The outer rail sample inlet rail 21 and the outer rail return rail 22 are arranged in parallel. The outer rail sample inlet rail 21 is used to receive new samples input by external devices, and the outer rail return rail 22 is used to output samples. The outer rail can transport the tested samples to external devices. The inner rail sample inlet rail 23 and the inner rail return rail 24 are arranged in parallel. The inner rail sample inlet rail 23 is used to convey samples to the detection area 1, and the inner rail return rail 24 is used to output samples to the buffer mechanism 3. When a new sample enters the sample analysis system through the outer rail sample inlet rail 21 from an external device, if there is an empty space in the detection area 1 for testing the new sample, the gripper 25 moves the new sample to the inner rail sample inlet rail 23, and the inner rail sample inlet rail 23 then transports the new sample to the detection area 1 for testing by the detection area 1. After the new sample is tested, the gripper 25 moves the tested sample to the inner rail return rail 24, and the inner rail return rail 24 transports the tested sample to the handling mechanism 5, and then the handling mechanism 5 moves the sample to the buffer mechanism 3 for temporary storage; when the sample on the buffer mechanism 3 needs to be retested, the handling mechanism 5 transports the sample to be retested on the buffer mechanism 3 to the sample addition position 42, and the sample addition mechanism 41 then aspirates the sample liquid from the sample to be retested and transfers it to the detection area 1 for testing; when the sample on the buffer mechanism 3 does not need to be retested, the handling mechanism 5 transports the sample that does not need to be retested to the outer rail return rail 22, and the outer rail return rail 22 then transports the sample that does not need to be retested to an external device.

[0044] See Figure 1 and Figure 2 In some embodiments, the inner rail sample injection rail 23, the inner rail return rail 24 and the sample submission mechanism 4 are located on the same side of the buffer mechanism 3. When the handling mechanism 5 is a handling vehicle, the handling mechanism 5 can rely on linear travel to achieve the switching of the docking positions of the inner rail sample injection rail 23, the inner rail return rail 24 and the sample submission mechanism 4, reducing the travel distance of the handling mechanism 5 and improving work efficiency. The handling mechanism 5 can use the same method to push the samples on the handling mechanism 5 onto the buffer mechanism 3 of the inner rail sample injection rail 23, the inner rail return rail 24 and the sample submission mechanism 4.

[0045] See Figure 1 In some embodiments, the handling mechanism 5 travels in a straight line. The movement path of the handling mechanism 5 is between the buffer mechanism 3 and the sample submission mechanism 4, and the movement path of the handling mechanism 5 is between the emergency detection loading position 6 and the sample submission mechanism 4. The emergency detection loading position 6 and the buffer mechanism 3 are located on the same side of the handling mechanism 5. With such a design, it is convenient for the handling mechanism 5 to carry samples back and forth, and when the handling mechanism 5 carries samples, it will not conflict with the actions of the sample addition mechanism 41 or the sampling needle 14, greatly improving the efficiency of sample detection.
