Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a sample processing system. Background Technology

[0002] Currently, sample handling in fully automated in vitro diagnostic (IVD) equipment largely requires manual intervention. To achieve full automation and unmanned operation of IVD equipment, a lifting hook and sample processing system, in conjunction with the analyzer, can enable automated sample loading and unloading in a laboratory workflow. Existing technology discloses a sample buffering and handling system with emergency and retesting functions. Through a buffering unit and a handling unit, it achieves fully automated sample loading for the IVD analyzer, ensuring efficient analyzer operation and improving diagnostic efficiency. Simultaneously, existing technology also discloses a hook lifting mechanism. The drive assembly rotates the cam arm until it abuts against the protrusion of the lifting body, causing the pulley to lift the hook assembly. The hook lifting mechanism has a power-off retention function, improving its operational stability in the event of a sudden power outage.

[0003] However, the aforementioned sample processing system cannot correct and position the sample holder during sample tube transfer, leading to situations such as the sample holder detaching from the guide rail or even colliding with the machine. Furthermore, the lifting hook in the aforementioned system is not compatible with various sample holders, limiting its applicability and practicality. Therefore, a sample processing system designed to address these problems is proposed. Utility Model Content

Detailed Implementation

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] like Figure 1 and Figure 2 As shown, in order to achieve the above objectives, this utility model provides a sample processing system, including: a frame 1 and a main rail 2 transfer module 3, a first guide rail 6 and a short rail 9 disposed on the frame 1.

[0037] The main rail 2 is mounted on the frame 1. The main rail 2 is equipped with a sample inlet positioning module 15 and a sample outlet positioning module 16. The sample inlet positioning module 15 and the sample outlet positioning module 16 scan the sample tube 401 on the main rail 2 to upload the information of the sample tube 401, so as to ensure that the correct sample holder 4 is always transmitted on the main rail 2, avoid errors in the transmitted sample holder 4 information, and improve the accuracy of sample transmission.

[0038] The transfer module 3 is mounted on the frame 1. The transfer module 3 is mounted on the assembly plate 302. The assembly plate 302 is mounted on the transfer frame. The two ends of the transfer frame are respectively provided with the sample inlet slot 303 and the sample outlet slot 304. The sample inlet slot 303 and the sample outlet slot 304 are slidably connected to the sample rack 4. The sample rack 4 is used to place the sample tube 401. The sample tube 401 stores the sample to be tested. In addition, the frame 1 is provided with the gripper mechanism 5. The gripper mechanism 5 is used to grip the sample tube 401 on the main rail 2 and transfer it to the transfer frame. Specifically, the gripper mechanism 5 will grip the sample tube 401 that has moved to the position of the sample inlet positioning module 15 on the main rail 2 and transfer it into the sample inlet slot 303. It will also grip the sample tube 401 in the sample outlet slot 304 and transfer it to the main rail 2 at the position of the sample outlet positioning module 16.

[0039] A first guide rail 6 is provided on the frame 1, and a trolley 7 is slidably provided on the first guide rail 6. Before the trolley 7 moves along the first guide rail 6 to the position of the sample inlet slot 303 or the sample outlet slot 304, the sample rack 4 in the sample inlet slot 303 or the sample outlet slot 304 can be further pushed to the designated position. The sample rack 4 in the sample inlet slot 303 or the sample outlet slot 304 is transferred by the trolley 7 in cooperation with the transfer module 3. It should be noted that a short rail 9 is provided on one side of the transfer module 3, and an analyzer is provided on the side of the short rail 9 away from the transfer module 3. The short rail 9 receives the sample rack 4 transferred from the transfer module 3 and further transmits it to the analyzer. The analyzer detects the specimen in the sample tube 401.

[0040] In addition, a through-beam sensor 8 is installed on the transfer module 3. The through-beam sensor 8 can detect whether the sample holder 4 has been pushed into place in the sample inlet slot 303 or the sample outlet slot 304. By detecting whether the sample holder 4 has been pushed into place in the sample inlet slot 303 or the sample outlet slot 304, the through-beam sensor 8 can prevent it from falling off the guide rail and damaging the sample. In addition, when the sample holder 4 in the sample inlet slot 303 or the sample outlet slot 304 is not pushed into place, the position of the sample holder 4 is re-corrected to prevent the trolley 7 from colliding with the sample holder 4 when it moves along the first guide rail 6, thereby avoiding damage to the instrument or the sample and further improving the safety of the sample holder 4 during transportation.

[0041] In use, the main rail 2 delivers the sample rack 4 to the sample injection positioning module 15 for scanning and positioning. The gripper mechanism 5 picks up the sample tube 401 and transfers it to the transfer frame of the transfer module 3, and places it in the sample rack 4 in the sample injection slot 303. The trolley 7 transfers the sample rack 4 in the sample injection slot 303 to the short rail 9. The sample rack 4 and the sample tube 401 placed on it are further transferred to the analyzer via the short rail 9. The analyzer detects the sample in the sample tube 401. After the sample detection is completed, the sample rack 4 is transported to the trolley 7 via the short rail 9. The trolley 7 transfers the sample rack 4 to the transfer frame on the transfer module 3 and places it in the sample discharge slot 304 on the transfer frame. The gripper mechanism 5 then picks up the sample tube 401 from the sample rack 4 in the sample discharge slot 304 and transfers it to the main rail 2 at the position of the sample discharge positioning module 16 for scanning, positioning and discharge. The sample rack 4 is positioned at a designated location on the main rail 2 by the sample injection positioning module 15 and the sample discharge positioning module 16, so as to ensure that the gripper mechanism 5 can accurately grasp or release the sample rack 4 and effectively ensure that the sample tube 401 can be accurately transmitted.

[0042] In one embodiment of this utility model, the main rail 2 includes an inlet guide rail 201 and an outlet guide rail 202 mounted on the frame 1. The inlet guide rail 201 transports the sample rack 4 to the position of the inlet positioning module 15, and the outlet guide rail 202 receives the sample rack 4 gripped by the gripper mechanism 5. The left half of the transfer frame is the inlet slot 303, and the right half is the outlet slot 304. The gripper mechanism 5 includes an inlet gripper 501 and an outlet gripper 502. The inlet gripper 501 grips the sample rack 4 on the inlet guide rail 201 and places it in the inlet slot 303, while the outlet gripper 502 grips the sample rack 4 from the outlet slot 304 and places it on the outlet guide rail 202.

[0043] It should be noted that the transfer module 3 is equipped with a sample injection positioning sensor 305 and a sample exit positioning sensor 306. The sample injection positioning sensor 305 and the sample exit positioning sensor 306 are located at the two ends of the transfer module 3, respectively. When the sample injection gripper 501 grabs the sample rack 4 on the sample injection guide rail 201 and places it in the sample injection slot 303, the sample rack 4 in the sample injection slot 303 will be pushed to the designated position for the trolley 7 to receive. The sample injection positioning sensor 305 detects whether the trolley 7 has moved to the designated position to ensure that the trolley 7 can move accurately along the first guide rail 6 to the corresponding end of the sample injection slot 303 to accurately receive the sample rack 4 in the corresponding sample injection slot 303. Similarly, when the sample rack 4 on the trolley 7 needs to be transported to the sample exit slot 304, the sample exit positioning sensor 306 detects whether the trolley 7 has moved to the corresponding end of the sample exit slot 304 to accurately push the sample rack 4 on the trolley 7 into the corresponding sample exit slot 304.

[0044] In one embodiment of this utility model, an encoder motor 10 is installed on the frame 1. The encoder motor 10 is connected to the trolley 7 via a first synchronous belt 17 to drive the trolley 7 to move back and forth on the first guide rail 6. The encoder motor 10 can detect whether it has lost steps in real time. If the encoder motor 10 loses steps, it will automatically initialize to ensure that the encoder motor 10 can drive the trolley 7 to move accurately a set distance on the first guide rail 6. This improves the coordination accuracy between the transfer module 3 and the trolley 7, thereby ensuring that the sample rack 4 and the sample tube 401 placed on it can be accurately transferred.

[0045] Meanwhile, several buffer slots 301 are arrayed between the sample inlet slot 303 and the sample outlet slot 304. When the sample tube 401 is injected at a speed greater than the detection speed of the analytical instrument, the sample rack 4 in the sample inlet slot 303 is first transported to the buffer slot 301 in sequence by the trolley 7. The sample tubes 401 on the sample rack 4 that cannot be detected in time are temporarily stored in the buffer slot 301 to ensure that the sample detection is carried out in an orderly manner.

[0046] In addition, a first positioning and clamping mechanism 13 and a second positioning and clamping mechanism 14 are provided on the transfer module 3. The first positioning and clamping mechanism 13 is located at the first end of the transfer frame, and the second positioning and clamping mechanism 14 is located at the second end of the transfer frame. Both the first positioning and clamping mechanism 13 and the second positioning and clamping mechanism 14 include a linear motor mounted on the assembly plate 302. The output end of the linear motor is provided with an elastic pressure head. The side of the sample inlet slot 303 facing the first positioning and clamping mechanism 13 and the side of the sample outlet slot 304 facing the second positioning and clamping mechanism 14 are both provided with through-holes. The through hole allows the linear motor in the first positioning and clamping mechanism 13 to drive the elastic pressure head through the through hole and hold the sample holder 4 in the sample inlet slot 303, effectively limiting the position of the sample holder 4 in the sample inlet slot 303. Similarly, the linear motor in the second positioning and clamping mechanism 14 drives the elastic pressure head through the through hole and holds the sample holder 4 in the sample outlet slot 304, effectively limiting the position of the sample holder 4 in the sample outlet slot 304. This ensures that when the sample inlet gripper 501 or the sample outlet gripper 502 grasps the sample tube 401, it will not move the corresponding sample holder 4, improving the safety of the sample tube 401 during transport. Preferably, the elastic pressure head is a spring, which can apply elastic pressure to the sample holder 4, avoiding crushing damage to the sample holder 4.

[0047] like Figure 3 and Figure 5 As shown, in one embodiment of this utility model, a first base plate 702 is provided at the bottom of the trolley 7. The first base plate 702 is slidably connected to the first guide rail 6. A second guide rail 703 is provided on the first base plate 702. The first guide rail 6 and the second guide rail 703 are perpendicular to each other. A lifting hook 11 is slidably provided on the second guide rail 703. The lifting hook 11 is used to grab the sample holder 4 in the sample inlet slot 303, the sample outlet slot 304, and the buffer slot 301. Specifically, a through hole is provided at the bottom of the sample inlet slot 303, the sample outlet slot 304, and the buffer slot 301. The through hole extends along the length of the sample inlet slot 303, the sample outlet slot 304, and the buffer slot 301. The sample rack 4 extends to the end of the trolley 7 near the sample inlet slot 303, the sample outlet slot 304, and the buffer slot 301. The bottom surface of the sample rack 4 is provided with a snap-fit ​​groove 402. The lifting hook 11 can move along the second guide rail 703 to directly below the sample inlet slot 303 and the sample outlet slot 304. When the lifting hook 11 can move upward, it snaps into the snap-fit ​​groove 402 on the bottom surface of the sample rack 4. The first base plate 702 is provided with a first drive motor 12. The first drive motor 12 is connected to the lifting hook 11 through the second synchronous belt 18. By controlling the forward and reverse rotation of the first drive motor 12, the lifting hook 11 can be driven to move back and forth on the second guide rail 703.

[0048] A support plate assembly 701 is provided on the first base plate 702. The support plate assembly 701 is equipped with a first sample rack sensor 706, a second sample rack sensor 707, a sample rack track 704, and a presence / absence sensor 705. The sample rack track 704 is used to transport the sample rack 4. The presence / absence sensor 705 is used to detect whether the sample rack 4 is present on the sample rack track 704. When the sample rack 4 is grasped by the lifting hook 11 and moves along the second guide rail 703 with the lifting hook 11, the sample rack 4 can be confined within the sample rack track 704 and can engage with the short rail 9 to ensure that the sample rack 4 can be accurately transported into the short rail 9 by the lifting hook 11. Additionally, the first sample rack sensor 706 is located at the left end of the sample rack track 704 and is used to assist in detecting the position of the corresponding sample inlet slot 303, sample outlet slot 304, or buffer slot 301 relative to the sample rack track 704, ensuring that the sample rack 4 can accurately enter the sample rack track 704 under the action of the lifting hook 11. The second sample rack sensor 707 is located at the right end of the sample rack track 704 and is used to assist in detecting the position of the short rail 9 relative to the sample rack track 704, so as to ensure that the sample rack 4 can accurately enter the sample rack track 704 under the action of the lifting hook 11.

[0049] like Figure 4 As shown, in one embodiment of the present invention, the lifting hook 11 includes: a second base plate 1109, the second base plate 1109 being slidably connected to a second guide rail 703, a second drive motor 1105 being provided on one side of the second base plate 1109, a drive shaft 1107 being provided at the output end of the second drive motor 1105, a guide plate 1108 being sleeved on the outer side of the drive shaft 1107, and a first U-shaped groove 1112 and a second U-shaped groove 1113 being provided at both ends of the guide plate 1108, specifically, the first U-shaped groove 1112 being provided at the left end of the guide plate 1108, and the second U-shaped groove 1113 being provided at the right end of the guide plate 1108. In addition, a first hook 1101 is slidably disposed on the second base plate 1109, and a first bearing 1106 is disposed on the side of the bottom end of the first hook 1101, and the first bearing 1106 is slidably connected to the first U-shaped groove 1112; a second hook 1104 is slidably disposed on the second base plate 1109, and a second bearing 1110 is disposed on the side of the bottom end of the second hook 1104, and the second bearing 1110 is slidably connected to the second U-shaped groove 1113.

[0050] It should be noted that when transporting smaller sample racks 4, taking a five-hole sample rack 4 as an example, when the second drive motor 1105 is rotated in the forward direction, the drive shaft 1107 drives the left end of the guide plate 1108 to rise. At this time, the first hook 1101 is lifted upward and inserted into the locking groove 402 on the bottom surface of the sample rack 4. When transporting larger sample racks 4, taking a ten-hole sample rack 4 as an example, when the second drive motor 1105 is rotated in the reverse direction, the drive shaft 1107 drives the right end of the guide plate 1108 to rise. At this time, the second hook 1104 is lifted upward and inserted into the locking groove 402 on the bottom surface of the sample rack 4. When the first hook 1101 rises, the second hook 1104 descends synchronously, and when the second hook 1104 rises, the first hook 1101 descends synchronously, ensuring that the lifting hook 11 can be used for various sample racks 4, thus improving practicality.

[0051] It should be further explained that an optical sensor 1102 is set on the second base plate, and a light-shielding plate 1111 is set on the first hook 1101. The light-shielding plate 1111 works with the optical sensor 1102 to complete the initialization. Specifically, when the light-shielding plate 1111 is below the optical sensor 1102, the second drive motor 1105 is controlled to rotate forward. The second drive motor 1105 drives the light-shielding plate 1111 to move upward relative to the second base plate with the first hook 1101 until the light-shielding plate 1111 triggers the optical sensor 1102, and controls the second drive motor 1105 to stop running. At this time, the top surfaces of the first hook 1101 and the second hook 1104 remain flat. When the light-shielding plate 1111 is above the optical sensor 1102, the second drive motor 1105 is reversed. The second drive motor 1105 drives the light-shielding plate 1111 to move downward relative to the second base plate along with the first hook 1101. After the light-shielding plate 1111 triggers the optical sensor 1102, the second drive motor 1105 continues to reverse until the light-shielding plate 1111 no longer triggers the optical sensor 1102. At this time, the second drive motor 1105 stops running, and the top surfaces of the first hook 1101 and the second hook 1104 remain flat. By controlling the lifting hook 11 to keep the top surfaces of the first hook 1101 and the second hook 1104 flat in the initial state, it is effectively ensured that the first hook 1101 and the second hook 1104 can be used independently without being affected by the size and shape of the sample holder 4.

[0052] Preferably, the upper ends of the first hook 1101 and the second hook 1104 are set in an L-shape, which allows the first hook 1101 and the second hook 1104 to hook onto the snap-fit ​​groove 402 at the bottom of the sample rack 4, or to directly hook onto the bottom surface of the sample rack 4. On the other hand, the arrangement of the first hook 1101 and the second hook 1104 can expand the overall range of motion of the lifting hook 11, allowing the lifting hook 11 to grab the sample rack 4 from a greater distance.

[0053] In addition, two guide rails 1103 are set on the second base plate. The two guide rails 1103 are slidably connected to the first hook 1101 and the second hook 1104 respectively. Through the cooperation of the two guide rails 1103 with the first hook 1101 and the second hook 1104 respectively, the movement path of the first hook 1101 and the second hook 1104 can be corrected and limited, effectively improving the cooperation accuracy between the lifting hook 11 and the sample frame 4.

[0054] In use, the sample tube 401 is transported along the sample inlet guide rail 201 to the sample inlet positioning module 15 for scanning and positioning. The sample inlet gripper 501 grasps the sample tube 401 and transfers it to the sample rack on the transfer module 3, and places it sequentially into the sample rack 4 in the sample inlet slot 303. The encoder motor 10 drives the trolley 7 to move along the first guide rail 6 to the sample inlet slot 303 via the first synchronous belt 17. The first drive motor 12 rotates forward to drive the lifting hook 11 to move along the second guide rail 703 to the bottom of the sample rack 4 in the sample inlet slot 303. The second drive motor 1105 rotates forward to drive the left end of the guide plate 1108 to rise. The first hook 1101 is lifted upward and inserted into the snap-fit ​​groove 402 on the bottom surface of the sample rack 4. The reverse rotation drives the lifting hook 11 to move along the second guide rail 703 away from the sample inlet slot 303. The encoder motor 10 drives the trolley 7 along the first guide rail 6 away from the sample inlet slot 303 and to the short rail 9 until the sample rack track 704 is aligned with the short rail 9. The first drive motor 12 further reverses to drive the lifting hook 11 to move along the second guide rail 703 until the sample rack 4 moves along the sample rack track 704 to the short rail 9. The second drive motor 1105 reverses to drive the left end of the guide plate 1108 to descend. The first hook 1101 moves downward and disengages from the locking groove 402 on the bottom surface of the sample rack 4. The sample rack 4 and the sample tube 401 placed on it are further transferred to the analyzer for detection via the short rail 9. After sample testing is completed, the sample rack 4 and the sample tube 401 placed above it are transported to the sample rack track 704 via the short rail 9. The second drive motor 1105 rotates forward to drive the left end of the guide plate 1108 to rise. The first hook 1101 is lifted upward and inserted into the locking groove 402 on the bottom surface of the sample rack 4. The first drive motor 12 rotates forward to drive the lifting hook 11 to enter the sample rack track 704 along the second guide rail 703. The encoder motor 10 drives the trolley 7 to move along the first guide rail 6 to the sample slot 304 via the first synchronous belt 17. At this point, the first drive motor 12 rotates in the opposite direction to drive the lifting hook 11 to enter the sample slot 304 below along the second guide rail 703. At this time, the sample rack 4 moves into the sample slot 304, and the second drive motor 1105 rotates in the opposite direction to drive the left end of the guide plate 1108 to descend. The first hook 1101 moves downward to disengage from the snap-fit ​​groove 402 on the bottom surface of the sample rack 4, and the sample dispensing gripper 502 grabs the sample tube 401 and transfers it to the sample dispensing positioning module 16 on the sample dispensing guide rail 202 for scanning, positioning, and dispensing, thus completing the sample testing process.

[0055] In summary, the through-beam sensor 8 detects whether the sample holder 4 is pushed into place in the sample inlet slot 303 and the sample outlet slot 304, preventing it from detaching from the guide rail and damaging the sample. When the sample holder 4 is not pushed into place in the sample inlet slot 303 and the sample outlet slot 304, the position of the sample holder 4 is corrected a second time to prevent the trolley 7 from colliding with the sample holder 4 when it moves along the first guide rail 6, effectively improving the safety of the sample holder 4 during transmission.
