[0089] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.
[0090] The sample testing device of this utility model is described below with reference to the accompanying drawings.
[0091] like Figure 2 and Figure 3 As shown, this utility model provides a sample testing device, which includes a sample testing module 10. The sample testing module 10 includes a frame 20 and a pushing component 60. The frame 20 includes a vertical plate 21 and a mounting base 22 disposed on the vertical plate 21. The pushing component 60 includes a sliding base 61 and a pushing chamber door 62. The sliding base 61 is slidably disposed on the mounting base 22 and is used for placing the sample testing box 200. The lower end of the pushing chamber door 62 is rotatably disposed on the mounting base 22. The pushing chamber door 62 is connected to the sliding base 61 and is used for pushing and pulling the sliding base 61 to slide.
[0092] Specifically, the sliding base 61 supports the sample detection box 200, and the push door 62 can rotate relative to the mounting base 22 to drive the sliding base 61 to slide. When the sample detection box 200 needs to be placed, the push door 62 rotates away from the mounting base 22 to pull the sliding base 61 away from the upright plate 21, thus facilitating the placement of the sample detection box 200 on the sliding base 61. After the sample detection box 200 is placed stably, the push door 62 is pushed towards the mounting base 22 to push the sliding base 61 to slide above the mounting base 22. The mounting base 22 stably supports the sample detection box 200 on the sliding base 61. The sample detection box 200 can be placed without the operator having to reach into the rack 20. The sample detection box 200 is easy to place and easy to observe its position on the sliding seat 61, preventing the sample detection box 200 from shifting. The push door 62 can cover the outside of the sample detection box 200 and the rack 20, preventing external impurities and contaminants from entering the rack 20 and causing sample contamination, thus improving the accuracy of the test results. Furthermore, the sliding motion of the sliding seat 61 by the rotation of the push door 62 shortens the sliding stroke of the sliding seat 61, reduces the lateral space occupied by the sample detection module 10, and improves space utilization.
[0093] In this embodiment of the utility model, the sample detection module 10 further includes a lifting mechanism 40. The lifting mechanism 40 includes a first lifting drive component 41, a lifting block 42, and a lifting door buckle plate 44. The first lifting drive component 41 is disposed on the upper side of the upright plate 21 and is drivenly connected to the lifting block 42. The lifting door buckle plate 44 is disposed on the lifting block 42 and is provided with a door buckle 441. The upper end of the push door 62 is provided with a connecting buckle 621 that engages with the door buckle 441.
[0094] like Figures 2 to 5 As shown, the lifting block 42 can drive the lifting door latch 44 to rise and fall, and the push chamber door 62 rotates towards the mounting base 22 to push the sliding base 61 to slide above the mounting base 22, so that the mounting base 22 stably supports the sample detection box 200 on the sliding base 61. The first lifting drive component 41 drives the lifting block 42 to fall, so that the lifting block 42 drives the lifting door latch 44 to fall. The door latch 441 on the lifting door latch 44 falls down to engage with the connecting latch 621 on the push chamber door 62 to restrict the rotation of the push chamber door 62, so that the push chamber door 62 can block one side of the sample detection box 200 to prevent impurities, contaminants, etc. from entering the sample detection box 200 and contaminating the sample.
[0095] In the embodiments of this utility model, such as Figure 2 , Figure 3 , Figure 6 , Figure 10 and Figure 11As shown, the frame 20 also includes a side plate 23 and a top plate 24. The upright plate 21 is located on one side of the side plate 23, and the top plate 24 is located at the upper end of the upright plate 21. The first lifting drive component 41 can be a lead screw motor in the prior art. The first lifting drive component 41 is installed on the top plate 24, and the drive lead screw of the first lifting drive component 41 extends downward through the top plate 24. The lifting block 42 is sleeved on the drive lead screw of the first lifting drive component 41 and threadedly connected to the drive lead screw, so that the first lifting drive component 41 can drive the lifting block 42 to rise and fall. The upright plate 21 is provided with a fixing plate 26 on the same side as the mounting base 22. The fixing plate 26 is provided with a guide rod 46, which extends upward and passes through the lifting block 42. The guide rod 46 guides the lifting block 42 to rise and fall, improving the smoothness of the lifting of the lifting block 42.
[0096] Furthermore, the lifting block 42 is provided with a first baffle 421, and the side plate 23 is provided with a first sensor 231 for detecting the position information of the first baffle 421. When the first lifting drive 41 drives the lifting block 42 to rise to the initial position, the first sensor 231 can detect the position information of the first baffle 421. Then, based on the detection result of the first sensor 231, it can be determined that the lifting block 42 drives the pickup rod 43 to rise above the fixed plate 26, which is convenient for placing the sample detection box 200 and effectively prevents interference between the pickup rod 43 and the sample detection box 200.
[0097] Understandably, the lifting door latch plate 44 is movably supported on the lifting block 42, and the upper end of the lifting door latch plate 44 passes through the top plate 24, so that the lifting block 42 can still descend relative to the lifting door latch plate 44 when the door latch 441 and the connecting latch 621 are engaged, thereby driving the pickup rod 43 to descend. The lifting stroke of the lifting door latch plate 44 and the lifting stroke of the pickup rod 43 do not interfere with each other, and the structural design is reasonable.
[0098] Furthermore, such as Figure 3 , Figure 4 , Figure 10 and Figure 11As shown, the lifting door latch 44 includes a lifting part 442 and a guide part 443. The lifting part 442 is movably supported on the lifting block 42 and its upper end passes through the top plate 24. The guide part 443 is connected to the lower end of the lifting part 442 and extends downward. The door latch 441 is provided on the guide part 443 and is used to engage with the connecting latch 621 to restrict the rotation of the push door 62. The upright plate 21 is also provided with two surrounding plates 25 on the same side as the mounting base 22, and the two surrounding plates 25 are arranged at intervals in the left and right direction. One of the surrounding plates 25 is provided with a first guide groove 251. The lower end of the guide part 443 extends into the first guide groove 251 and slides in cooperation with the first guide groove 251. The first guide groove 251 plays the role of guiding the lifting door latch 44 to move up and down, thereby improving the smoothness of the lifting door latch 44.
[0099] Furthermore, the lifting part 442 is provided with a second baffle 444, and the side plate 23 is provided with a second sensor 232 for detecting the position information of the second baffle 444. According to the detection result of the second sensor 232, it can be determined that the door buckle 441 is engaged with the connecting buckle 621, thereby determining that the push door 62 is protected on one side of the sample detection box 200.
[0100] In this embodiment of the utility model, the sliding seat 61 includes a sliding plate 611 and a connecting plate 612. The sliding plate 611 is slidably disposed on the mounting base 22 and is used for placing the sample detection box 200. The connecting plate 612 is connected to the sliding plate 611 and is bent downward from the sliding plate 611. The push chamber door 62 includes a door panel 622 and a connecting plate 623 disposed at the lower end of the door panel 622. The upper end of the door panel 622 is provided with a connecting buckle 621. The connecting plate 623 is rotatably disposed on the mounting base 22, and a connecting groove 6231 for the connecting plate 612 to extend into is formed on the connecting plate 623.
[0101] like Figures 2 to 5 As shown, the door panel 622 can drive the connecting plate 623 to rotate relative to the mounting base 22, so that the connecting plate 623 pushes and pulls the adapter plate 612 through the connecting groove 6231, thereby causing the adapter plate 612 to push and pull the sliding plate 611 to slide relative to the mounting base 22. When the door panel 622 drives the sliding plate 611 to a position away from the upright plate 21, the sample detection box 200 can be placed on the sliding plate 611, which is convenient and quick to install. The sliding plate 611 has a placement groove 6111 for the sample detection box 200 to extend into. The placement groove 6111 plays the role of positioning and installing the sample detection box 200, improving the placement stability. Furthermore, when the door panel 622 drives the sliding plate 611 to slide above the mounting base 22, the door panel 622, the fixing plate 26 and the two surrounding plates 25 cooperate to surround the outside of the sample detection box 200, effectively preventing impurities, contaminants and other contaminants from entering the sample detection box 200 and causing contamination to the sample, thus improving the accuracy of the test results.
[0102] In this embodiment of the utility model, the mounting base 22 is provided with a mounting post 221, and the connecting plate 623 is provided with a mounting sleeve 6232. The mounting sleeve 6232 is rotatably sleeved on the mounting post 221, and a torsion spring 6233 is sleeved on the mounting sleeve 6232. The two torsion arms of the torsion spring 6233 are respectively connected to the mounting base 22 and the door panel 622 in a one-to-one correspondence. Figures 2 to 5 As shown, the mounting sleeve 6232 is used for the mounting column 221 to extend into, and the mounting sleeve 6232 can rotate relative to the mounting column 221, so that the door panel 622 can drive the connecting plate 623 to rotate relative to the mounting base 22, thereby pushing and pulling the sliding plate 611 to slide. A torsion spring 6233 is sleeved on the outer side of the mounting sleeve 6232. When the door latch 441 is engaged with the connecting latch 621, the door panel 622 and the mounting base 22 cooperate to compress the torsion spring 6233. When the door latch 441 rises and releases the limit on the door panel 622, the elastic restoring force of the torsion spring 6233 acts on the door panel 622, causing the door panel 622 to rotate away from the mounting base 22 and pull the sliding plate 611 to slide away from the upright plate 21, thereby facilitating the placement of the sample detection box 200 on the sliding plate 611 and improving the degree of automation.
[0103] In this embodiment of the present invention, the sample detection module 10 further includes a detection device 50. The detection device 50 includes a housing 51, a temperature control mechanism, and a detection mechanism 52 disposed in the housing 51 for detecting the reaction tube 204 of the sample detection box 200. The housing 51 is disposed on the side of the upright plate 21 facing away from the mounting base 22 and has an insertion port 511 for the reaction tube 204 to extend into. The temperature control mechanism includes a heating element 53 and two heat-conducting blocks 54 spaced apart in the housing 51. An insertion gap 541 communicating with the insertion port 511 is formed between the two heat-conducting blocks 54, and a heating element 53 is provided on the side of each heat-conducting block 54 facing the insertion gap 541.
[0104] like Figures 6 to 9As shown, the detection device 50 includes a housing 51 and a temperature control mechanism and a detection mechanism 52 disposed within the housing 51. The temperature control mechanism includes two spaced heat-conducting blocks 54, with an insertion gap 541 formed between the two heat-conducting blocks 54. The temperature control mechanism also includes heating elements 53, which are the same number as the heat-conducting blocks 54 and are disposed on the side of the heat-conducting blocks 54 facing the insertion gap 541. The housing 51 has an insertion port 511, which communicates with the insertion gap 541. The detection mechanism 52 is disposed on the side of the heat-conducting blocks 54 away from the insertion port 511. The reaction tube 204 on the sample detection box 200 can be inserted into the insertion gap 541 through the insertion port 511, so that the two heating plates 53 are respectively attached to the two sides of the reaction tube 204 to heat the reaction tube 204. The heat generated by the heating plates 53 can be quickly conducted to the heat conduction block 54 after heating to cool the reaction tube 204. This realizes the cyclic heating and cooling process of the sample to be tested in the reaction tube 204. The detection mechanism 52 can detect the sample in the reaction tube 204 after the sample heating and cooling process is completed to quickly obtain the detection results. It has a high degree of functional integration and occupies little space.
[0105] In this embodiment of the present invention, a guide wall 542 is formed on the side of the heat-conducting block 54 facing the insertion gap 541. The guide wall 542 is inclined from bottom to top towards the insertion gap 541. The temperature control mechanism also includes a pushing component 55 and a resetting component 56. The pushing component 55 includes a push block 551 extending into the insertion gap 541. The lifting mechanism 40 also includes a lifting push-pull plate 45 disposed on the lifting block 42. The lifting push-pull plate 45 is connected to the push block 551 and is used to drive the push block 551 to slide along the extension direction of the guide wall 542, so that the push block 551 pushes the two heat-conducting blocks 54 to move in opposite directions. The resetting component 56 includes a first spring 561 disposed between the housing 51 and the heat-conducting block 54. The two ends of the first spring 561 respectively abut against the housing 51 and the heat-conducting block 54.
[0106] like Figures 6 to 9As shown, the lifting block 42 can drive the lifting push-pull plate 45 to rise and fall. Two heat-conducting blocks 54 are spaced apart in the housing 51 in the left and right direction. A guide wall 542 extending in the up and down direction is formed on the side of the heat-conducting block 541 facing the insertion gap 541. The guide wall 542 is inclined in the insertion gap 541 in the direction from bottom to top. The push block 551 is installed in the insertion gap 541 and can slide along the extension direction of the guide wall 542. The lifting push-pull plate 45 is connected to the push block 551 and is used to drive the push block 551 to slide. When the reaction tube 204 containing the sample to be tested is inserted from the insertion port 511 into the insertion gap 541, the first lifting drive 41 drives the lifting block 42 to rise, so that the lifting block 42 drives the lifting push-pull plate 45 to pull the push block 551 upward. The push block 551 slides from the lower end to the upper end of the guide wall 542, so that the push block 551 pushes the two heat conducting blocks 54 to move in opposite directions through the guide wall 542. The insertion gap 541 between the two heat conducting blocks 54 increases, so that the reaction tube 204 will not rub against the heating element 53 during the process of extending into the insertion gap 541, thus extending the service life of the heating element 53 and greatly reducing the frequency of maintenance and replacement of the heating element 53.
[0107] Furthermore, the heating element 53 is positioned corresponding to the insertion port 511, and the guide wall 542 is spaced apart from the heating element 53 in the vertical direction. One end of the first spring 561 abuts against the housing 51, and the other end of the first spring 561 abuts against the heat-conducting block 54. When the reaction tube 204 is inserted into place, the heat-conducting block 54 and the housing 51 cooperate to compress the first spring 561. The first lifting drive 41 drives the lifting block 42 to descend, so that the lifting block 42 pushes the push block 551 downward through the lifting push-pull plate 45. When the first spring 561 moves, the elastic restoring force acts on the heat-conducting block 54, causing the two heat-conducting blocks 54 to move towards each other, reducing the insertion gap 541 between the two heat-conducting blocks 54. This causes the two heating elements 53 to respectively adhere to both sides of the reaction tube 204 to heat the reaction tube 204. The heat generated by the heating elements 53 can be quickly conducted to the heat-conducting block 54 after heating to cool the reaction tube 204, thus realizing the cyclic heating and cooling process of the sample to be tested in the reaction tube 204.
[0108] Understandably, the lifting and sliding plate 45 is movably supported on the lifting block 42, and the upper end of the lifting and sliding plate 45 passes through the top plate 24, so that the lifting block 42 can still descend relative to the lifting and sliding plate 45 when the heating element 53 is in contact with the reaction tube 204, thereby driving the pickup rod 43 to descend. The lifting stroke of the lifting and sliding plate 45 and the lifting stroke of the pickup rod 43 do not interfere with each other, and the structural design is reasonable.
[0109] In this embodiment of the utility model, the pushing component 55 further includes a sliding plate 552 and a push-pull rod 553. The sliding plate 552 is disposed inside the housing 51. The push block 551 and the push-pull rod 553 are disposed on both sides of the sliding plate 552. A sliding groove 512 is provided on the housing 51. A locking hole 451 is provided on the lifting push-pull plate 45. The push-pull rod 553 can slide through the sliding groove 512 and extend into the locking hole 451. The push block 551 is connected to the lifting push-pull plate 45 through the sliding plate 552 and the push-pull rod 553.
[0110] like Figures 6 to 11 As shown, a push block 551 is provided on one side of the sliding plate 552. The push block 551 extends into the insertion gap 541 and slides in cooperation with the guide wall 542. A push-pull rod 553 is provided on the other side of the sliding plate 552 and extends out of the housing 51 through the sliding groove 512 on the housing 51. The sliding groove 512 extends in the vertical direction, and the push-pull rod 553 extends into the locking hole 451 of the lifting push-pull plate 45 to connect with the lifting push-pull plate 45. The lifting push-pull plate 45 drives the push-pull rod 553 to slide upward along the sliding groove 512, so that the push-pull rod 553 drives the push block 551 from the guide wall 542 via the sliding plate 552. The lower end slides upward, causing the pusher block 551 to push the two heat-conducting blocks 54 to move in opposite directions to prevent wear on the heating element 53 when the reaction tube 204 is inserted; and the pusher block 553 slides downward along the slide groove 512 via the lifting pusher plate 45, so that the pusher block 553 drives the pusher block 551 to slide from the upper end to the lower end of the guide wall 542 via the sliding plate 552, thereby causing the two heat-conducting blocks 54 to move towards each other to the contact position under the elastic restoring force of the corresponding first spring 561, so that the heating element 53 is in contact with and presses the reaction tube 204 to improve the uniformity of heating and improve the heating effect.
[0111] In this embodiment of the invention, multiple push blocks 551 are provided, and these push blocks 551 are spaced apart on the sliding plate 552. A guide wall 542 is formed on the heat-conducting block 54 corresponding to the position of each push block 551. Figure 8 and Figure 9As shown, the sliding plate 552 has two push blocks 551 arranged at intervals in the vertical direction on the side facing the inside of the housing 51. Each heat-conducting block 54 has a guide wall 542 corresponding to the position of each push block 551, so that by pushing and pulling the sliding plate 552, the two push blocks 551 can be driven to slide synchronously along the corresponding guide wall 542, thereby improving the smoothness and stability of the two heat-conducting blocks 54 moving towards or away from each other. In addition, the push blocks 551 are wedge-shaped, and each of the two heat-conducting blocks 54 has a guide wall 542 for sliding cooperation with the push block 551 at the position corresponding to the push block 551. The wedge-shaped push block 551 can stick to the guide wall 542 and stably support the heat-conducting block 54 when sliding to any position along the guide wall 542, improving the smoothness of the movement of the heat-conducting block 54. Moreover, by pushing the two heat-conducting blocks 54 with the wedge-shaped push block 551, the insertion gap 541 between the two heat-conducting blocks 54 can be steadily increased, effectively preventing the reaction tube 204 from wearing the heating plate 53.
[0112] In this embodiment of the invention, the reset assembly 56 further includes a first mounting rod 562. A first mounting groove 543 is formed on the side of the heat-conducting block 54 facing away from the guide wall 542. The first mounting rod 562 is disposed on the housing 51 and extends into the first mounting groove 543. A first spring 561 is sleeved on the first mounting rod 562. Figure 8 As shown, one end of the first mounting rod 562 is connected to the housing 51, and the other end of the first mounting rod 562 extends into the first mounting groove 543. The first spring 561 is sleeved on the first mounting rod 562, one end of the first spring 561 abuts against the housing 51, and the other end of the first spring 561 abuts against the heat-conducting block 54. When the lifting and pulling plate 45 drives the push block 551 to push the two heat-conducting blocks 54 to move in opposite directions, the heat-conducting blocks 54 cooperate with the housing 51 to compress the first spring 561. When the reaction tube 204 extends between the two heating plates 53, the lifting and pulling plate 45 drives the push block 551 to slide downward. The elastic restoring force of the first spring 561 acts on the heat-conducting blocks 54, causing the two heat-conducting blocks 54 to move towards each other to a fitting position to heat the reaction tube 204. The elastic restoring force of the first spring 561 can also act on the heating plates 53 through the heat-conducting blocks 54, causing the heating plates 53 to move toward the insertion gap 541 to press the reaction tube 204, improving the heating uniformity of the reaction tube 204 and accelerating the heating rate. Furthermore, the first mounting rod 562 can use fasteners such as screws and pins in the prior art, which is convenient for installation and reduces costs.
[0113] Furthermore, the reset assembly 56 also includes a second mounting rod 564 and a second spring 563. The housing 51 is provided with a mounting ear 513, and the push block 551 is provided with a second mounting groove 5511 along the vertical direction. The second mounting rod 564 is provided on the mounting ear 513 and extends into the second mounting groove 5511. The second spring 563 is sleeved on the second mounting rod 564, and the two ends of the second spring 563 respectively abut against the mounting ear 513 and the push block 551.
[0114] like Figure 9 As shown, the housing 51 is provided with a mounting ear 513 extending into the housing 51, and the mounting ear 513 and the heat-conducting block 54 are arranged at intervals in the vertical direction. The push block 551 is provided with a second mounting groove 5511 extending in the vertical direction at the position corresponding to the mounting ear 513. One end of the second mounting rod 564 is connected to the mounting ear 513, and the other end of the second mounting rod 564 extends into the second mounting groove 5511. The second spring 563 is sleeved on the second mounting rod 564, one end of the second spring 563 abuts against the mounting ear 513, and the other end of the second spring 563 abuts against the bottom wall of the second mounting groove 5511. When the lifting and pulling plate 45 drives the push block 551 to push the two heat-conducting blocks 54 to move in opposite directions, the push block 551 cooperates with the mounting ear 513 to squeeze the second spring 563. When the reaction tube 204 extends between the two heating plates 53, the lifting and pulling plate 45 drives the push block 551 to slide downward. The elastic restoring force of the second spring 563 acts on the push block 551, so that the push block 551 can quickly return to its original position, improving the smoothness of the push block 551's return and sliding.
[0115] In this embodiment of the invention, the temperature control mechanism further includes a heat dissipation assembly 57. The heat dissipation assembly 57 includes a heat sink 571, a heat pipe 572, and a cooling fan 573. The heat sink 571 is disposed within the housing 51 and spaced apart from the heat-conducting block 54. The two ends of the heat pipe 572 are respectively embedded in the heat-conducting block 54 and the heat sink 571. The cooling fan 573 is disposed on one side of the heat sink 571 and located between the heat-conducting block 54 and the heat sink 571. Figure 7 and Figure 8 As shown, the heating element 53 is located on the side of the heat-conducting block 54 facing the insertion gap 541. The heating element 53 can be a thermoelectric semiconductor heating patch or a Peltier, which can generate heat. After the heating element 53 heats the reaction tube 204, the heat can be conducted through the heat-conducting block 54 to the heat-conducting pipe 572, and then through the heat-conducting pipe 572 to the heat sink 571 to achieve rapid cooling. The heat sink 571 and the heat-conducting block 54 are spaced apart in the housing 51, which saves space and allows the heat to dissipate quickly during the conduction process, thus improving the cooling rate.
[0116] Furthermore, the heat sink 571 includes multiple spaced heat dissipation fins 5711, and heat pipes 572 pass through the multiple heat dissipation fins 5711 respectively. The heat pipes 572 have high heat transfer efficiency, and the multiple heat dissipation fins 5711 increase the heat dissipation area, significantly improving the cooling rate. In addition, the cooling fan 573 is located between the heat conduction block 54 and the heat sink 571 and is used to blow air towards the heat sink 571, so that the heat on the heat dissipation fins 5711 can be quickly dissipated, further accelerating the cooling rate. In addition, the heat conduction block 54 and the heat sink 571 are located on both sides of the cooling fan 573. The heat conduction pipe 572 extends from the heat conduction block 54 towards the heat sink 571 and bypasses the cooling fan 573. The installation position of the cooling fan 573 increases the length of the heat conduction pipe 572, thereby increasing the distance between the heating element 53 and the heat sink 571, so that the heat can be gradually dissipated during the conduction process, improving the cooling effect.
[0117] In this embodiment of the present invention, the sample detection module 10 further includes a rotary drive mechanism 30, which is located on the lower side of the mounting base 22 and is used to drive the rotary valve 201 of the sample detection box 200 to rotate to connect the pipetting orifice 202 and any one of the liquid storage chambers 203. The lifting mechanism 40 further includes a pickup rod 43 located on the lifting block 42, which is used to pick up the pipetting plunger in the pipetting orifice 202.
[0118] It should be noted that the sample detection device of this utility model embodiment can process and detect samples within the sample detection box 200, such as... Figure 14 and Figure 15 As shown, the sample detection box 200 has multiple liquid storage chambers 203, which are used to hold samples, eluents, reagents, etc. The sample detection box 200 is equipped with a rotary valve 201, which has a pipetting orifice 202 and a pipetting channel 2012 communicating with the pipetting orifice 202. A slot 2011 is formed on the lower side of the rotary valve 201. By rotating the rotary valve 201, the pipetting channel 2012 can be connected to any one of the liquid storage chambers 203, thereby allowing the pipetting orifice 202 to be connected to any one of the liquid storage chambers 203 through the pipetting channel 2012. A pipetting plunger is placed in the pipetting orifice 202. A reaction tube 204 is provided on the outside of the sample detection box 200, and the reaction tube 204 is connected to one of the liquid storage chambers 203. By placing the sample detection box 200 in the sample detection device, the sample can be processed and detected.
[0119] Specifically, a rotary drive mechanism 30, a mounting base 22, and a lifting mechanism 40 are sequentially arranged from bottom to top on one side of the upright plate 21. The mounting base 22 supports the sample detection box 200 so that the rotary drive mechanism 30 can drive the rotary valve 201 of the sample detection box 200 to rotate from the lower side of the mounting base 22, so that the pipetting orifice 202 communicates with any of the liquid storage chambers 203. The lifting mechanism 40 includes a lifting block 42, a pickup rod 43 connected to the lifting block 42, and a first lifting drive member 41 for driving the lifting block 42 to rise and fall. The first lifting drive member 41 drives the lifting block 42 to fall so that the pickup rod 43 picks up the pipetting plunger from the pipetting orifice 202. Then, the first lifting drive member 41 drives the lifting block 42 to rise so that the pickup rod 43 drives the pipetting plunger to rise. The liquid in the storage chamber 203 is drawn into the pipette orifice 202 to achieve pipetting. Then, the rotary valve 201 is driven to rotate by the rotary drive mechanism 30 so that the pipette orifice 202 is connected to multiple storage chambers 203 respectively. The pick rod 43 drives the pipette plunger to rise and fall to achieve sample extraction, pipetting and mixing pretreatment. After the sample pretreatment is completed, the pick rod 43 drives the pipette plunger to fall to inject the sample in the pipette orifice 202 into the reaction tube 204. Furthermore, a detection device 50 is provided on the other side of the upright plate 21. The reaction tube 204 can pass through the upright plate 21 and extend into the detection device 50. The detection device 50 is used to perform multiple heating and cooling treatments on the reaction tube 204 and to detect the processed sample in the reaction tube 204.
[0120] In the sample detection module 10 of this utility model embodiment, one side of the upright plate 21 is provided with a mounting base 22 for supporting the sample detection box 200, a rotary drive mechanism 30 for driving the rotary valve 201 to rotate, and a lifting mechanism 40 for picking up the pipette plunger and driving the pipette plunger to rise and fall. Through the cooperation of the rotary drive mechanism 30 and the lifting mechanism 40, the sample in the sample detection box 200 can be pre-treated by extraction, pipetting, and mixing. The other side of the upright plate 21 is provided with a detection device 50 for repeated heating and cooling treatment and detection of the sample. The sample detection module 10 has a compact structure, high functional integration, small size, and small space occupation. The advantages of fewer components significantly improve space utilization. Furthermore, when samples need to be tested, the sample testing box 200 only needs to be placed inside the sample testing equipment so that it is supported on the mounting base 22. The sample inside the sample testing box 200 can be processed and tested by the rotation drive mechanism 30, the lifting mechanism 40, and the testing device 50, realizing a rapid testing mode of sample in and result out. The testing time is short, improving testing efficiency. Moreover, the degree of automation is high, eliminating manual operation and reducing the risk of impurities and contaminants entering the sample testing box 200 and causing sample contamination, thus improving the accuracy of the test results.
[0121] In this embodiment of the utility model, the rotary drive mechanism 30 includes a rotary drive member 31 and a rotary locking pin 32. The rotary drive member 31 is disposed on the lower side of the mounting base 22, and the mounting base 22 is provided with a mounting hole 222 for the rotary locking pin 32 to pass through. One end of the rotary locking pin 32 is drivenly connected to the rotary drive member 31, and the other end of the rotary locking pin 32 is formed with a locking protrusion 321. The locking protrusion 321 is used to engage with the locking groove 2011 of the rotary valve 201.
[0122] like Figure 13 and Figure 14 As shown, the rotary drive 31 is located on the lower side of the mounting base 22, and the rotary locking pin 32 passes through the mounting hole 222. The lower end of the rotary locking pin 32 is driven to connect with the rotary drive 31 so that the rotary drive 31 can drive the rotary locking pin 32 to rotate. The upper end of the rotary locking pin 32 has a locking protrusion 321 that can extend into the locking groove 2011. The rotary drive 31 drives the rotary locking pin 32 to rotate so that the locking protrusion 321 drives the rotary valve 201 to rotate through the locking groove 2011, thereby causing the rotary valve 201 to rotate. The pipetting orifice 202 can be connected to any one of the storage chambers 203 through the pipetting channel 2012, realizing sample extraction, pipetting and mixing, with a high degree of structural integration; in addition, the size of the snap-fit protrusion 321 is gradually reduced along the radial direction of the rotating snap-fit post 32, and the size of the slot 2011 matches the size of the snap-fit protrusion 321 to effectively prevent the sample detection box 200 from being placed in reverse, ensuring that the reaction tube 204 can be inserted from the insertion port 511 into the insertion gap 541, with a reasonable structural design.
[0123] In this embodiment of the present invention, the sample detection module 10 further includes a magnetic attraction mechanism 70, which includes a second lifting drive member 71 and a magnetic attraction block 72. The second lifting drive member 71 is disposed on the mounting base 22 and is drivenly connected to the magnetic attraction block 72. The mounting base 22 has a through hole 223 for the magnetic attraction block 72 to pass through. Figure 10 and Figure 12 As shown, the second lifting drive 71 is used to drive the magnetic block 72 to lift. The magnetic block 72 can pass through the through hole 223 on the mounting base 22 and fit with the sample detection box 200 to perform magnetic attraction on the sample in the sample detection box 200. The magnetic attraction mechanism 70 is integrated on the mounting base 22, which saves space and eliminates the need for additional instruments for magnetic attraction, simplifying the sample extraction process and improving detection efficiency.
[0124] Furthermore, such as Figure 5 , Figure 11 and Figure 12As shown, the sliding plate 611 has a clearance hole 6112. When the sliding plate 611 slides above the mounting base 22, the clearance hole 6112 communicates with the through hole 223 so that the magnetic block 72 can pass through the clearance hole 6112 and the through hole 223 to fit against the sample detection box 200. In addition, the magnetic attraction mechanism 70 also includes a mounting bracket 73 and an adapter block 74. The mounting bracket 73 is disposed on the mounting base 22. The second lifting drive member 71 can be a lead screw motor in the prior art. The second lifting drive member 71 is mounted on the mounting bracket 73, and the adapter block 74 is sleeved on the mounting bracket 73. The second lifting drive 71 is connected to the drive screw and threadedly connected to the drive screw. The magnetic block 72 is disposed on the adapter block 74 so that the second lifting drive 71 can drive the magnetic block 72 to rise and fall through the adapter block 74, thereby facilitating the magnetic attraction of the sample in the sample detection box 200. The mounting base 22 is provided with a second guide groove 224 for the magnetic block 72 to extend into. The magnetic block 72 can slide up and down along the second guide groove 224. The second guide groove 224 plays the role of guiding the magnetic block 72 to rise and fall, improving the smoothness of the magnetic block 72's rise and fall.
[0125] Furthermore, the adapter block 74 is provided with a third baffle 741, and the side plate 23 is provided with a third sensor 233 and a fourth sensor 234 for detecting the position information of the third baffle 741. The third sensor 233 and the fourth sensor 234 are arranged at intervals in the vertical direction, and the third sensor 233 is located above the fourth sensor 234. When the second lifting drive 71 drives the magnetic block 72 to descend to the initial position, the fourth sensor 234 can detect the position information of the third baffle 741, and then determine the position of the magnetic block 72 below the sliding plate 611 based on the detection result of the fourth sensor 234, so that the sliding plate 611 can move away from the sliding plate 611. The upright plate 21 slides in a direction to place the sample detection box 200, effectively preventing interference between the magnetic block 72 and the sliding plate 611; when the second lifting drive 71 drives the magnetic block 72 to rise to the magnetic position, the third sensor 233 can detect the position information of the third baffle 741, and then determine the magnetic block 72 to rise to fit with the sample detection box 200 based on the detection result of the third sensor 233, so that the magnetic block 72 can perform magnetic attraction processing on the sample; in addition, the first sensor 231, the second sensor 232, the third sensor 233 and the third sensor 233 can all adopt photoelectric switches in the prior art, which are sensitive and reliable.
[0126] In this embodiment of the invention, the sample detection module 10 further includes a heating component 80, which includes a connecting bracket 81 and a heating block 82. The connecting bracket 81 is mounted on the frame 20, and the heating block 82 is mounted on the connecting bracket 81 and is used to fit against the sample detection box 200. The connecting bracket 81 is mounted on the side plate 23 and extends above the mounting base 22. The heating block 82 is mounted on the connecting bracket 81 and can fit against the sample detection box 200 to heat the sample inside the sample detection box 200. The structure has a high degree of integration and improves space utilization.
[0127] Furthermore, such as Figures 2 to 6 As shown, the heating assembly 80 also includes a heat insulation block 83 and an elastic sheet 84. The heat insulation block 83 is mounted on the connecting bracket 81, and the heating block 82 is mounted on the side of the heat insulation block 83 facing away from the upright plate 21. The heat insulation block 83 is used to insulate the heat generated by the heating block 82 and prevent the heat from being conducted to the upright plate 21, thereby improving the heating efficiency. The elastic sheet 84 is L-shaped. One end of the elastic sheet 84 is connected to one of the surrounding plates 25, and the other end of the elastic sheet 84 is connected to the side of the heat insulation block 83 facing the upright plate 21. A pressing block 6221 is provided on the side of the door panel 622 facing the upright plate 21. The pressing block 6221 is used to abut against the sample detection box 200 so that the pressing block 6221 can cooperate with the elastic sheet 84 to press the heating block 82 tightly and adhere it to the sample detection box 200, thereby further improving the heating rate.
[0128] In the embodiments of this utility model, such as Figure 1 As shown, the sample testing device also includes a housing 90, and the number of sample testing modules 10 is set to multiple. The multiple sample testing modules 10 are arranged sequentially inside the housing 90, and the housing 90 has a placement port 91 for the sample testing box 200 to be placed in. The number of placement ports 91 is consistent with the number of sample testing modules 10 and is set one-to-one. Specifically, the sample detection equipment is suitable for processing and detecting samples within multiple sample detection boxes 200. Multiple sample detection modules 10 are housed within the casing 90, arranged sequentially in a left-right direction. Each sample detection module 10 has a placement opening 91 on the casing 90, allowing the sample detection box 200 to be placed onto the sliding seat 61 from the placement opening 91. Each sample detection module 10 can automatically detect the samples within the sample detection box 200, and each module does not interfere with the others, significantly improving detection efficiency and space utilization. This achieves fully automated sample detection, effectively preventing sample contamination caused by contact with the environment during detection. Multiple sample detection modules 10 can simultaneously detect multiple samples, resulting in high detection efficiency. Each sample detection module 10 has a compact structure, high functional integration, and small footprint, improving space utilization. Furthermore, multiple sample detection modules 10 can achieve multi-throughput sample detection within limited space, further enhancing detection efficiency.
