Sample testing equipment pusher and sample testing equipment Technical Field

[0001] This invention belongs to the field of sample detection technology, specifically relating to a pusher device and a sample detection device. Background Technology

[0002] Nucleic acid amplification detection is a detection technique that amplifies and detects nucleic acid targets to quickly obtain test results. Multiplex nucleic acid amplification detection technology refers to the ability to simultaneously amplify and detect multiple nucleic acid targets in a single test operation. During multiplex nucleic acid amplification detection, the operator needs to place the sample detection kit into the sample detection device, ensuring precise and stable alignment between the kit containing the sample to be tested and the detection device. However, it is difficult for the operator to accurately determine the placement of the sample detection kit during this process. Misalignment, tilting, or inaccurate alignment of the sample detection kit can lead to uneven amplification of nucleic acid targets, reduced detection sensitivity, and consequently, affect the accuracy of the test results.

[0059] The specific embodiments of the present invention 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 present invention.

[0060] The pushing device of the sample detection equipment of the present invention will now be described with reference to the accompanying drawings.

[0061] As shown in Figures 1 to 5, the present invention provides a pushing device for a sample testing equipment. The pushing device includes a loading seat 10, a frame 20, and a pushing drive mechanism 30. The loading seat 10 is used to place the sample testing box 200. The frame 20 includes a side plate 22 with a guide groove 21. The guide groove 21 has a pushing guide section 211 extending laterally and a lifting guide section 212 extending vertically. The pushing drive mechanism 30 includes a connecting plate 31 and a pushing drive assembly. The loading seat 10 is located at one end of the connecting plate 31, and the other end of the connecting plate 31 is provided with a sliding rod 311. The sliding rod 311 is slidably inserted into the guide groove 21. The pushing drive assembly is used to drive the sliding rod 311 to slide from the end of the pushing guide section 211 away from the lifting guide section 212 to the lower end of the lifting guide section 212, so that the sliding rod 311 drives the loading seat 10 to move from the loading position to the testing position through the connecting plate 31.

[0062] It should be noted that the pushing device of this embodiment of the invention can be applied in a sample detection device. The pushing device is used to load and push the sample detection box 200 so that the sample detection box 200 containing the sample to be tested can be docked with the detection device of the sample detection device, thereby realizing the amplification and detection of the sample.

[0063] Specifically, the loading seat 10 is located on one side of the side plate 22 and connected to the upper end of the connecting plate 31. The lower end of the connecting plate 31 is provided with a sliding rod 311, which extends into the guide groove 21 opened on the side plate 22. The guide groove 21 has a push guide section 211 and a lifting guide section 212 connected to the push guide section 211. The push guide section 211 extends in the front-back direction, and the lifting guide section 212 extends in the up-down direction. The upper end of the lifting guide section 212 is connected to the rear end of the push guide section 211. The push drive assembly is driven to connect with the sliding rod 311 and can drive the sliding rod 311 to slide along the push guide section 211 and along the lifting guide section 212. The sliding rod 311 slides to drive the connecting plate 31 to move, so that the connecting plate 31 drives the loading seat 10 to move relative to the side plate 22.

[0064] When the sample test box 200 needs to be placed, the push drive assembly drives the sliding rod 311 to slide to the front end of the push guide section 211, so that the sliding rod 311 drives the loading seat 10 to move to the loading position through the connecting plate 31. When the device is in the position, the loading seat 10 extends from the front end of the side plate 22 to the outside of the frame 20, making it convenient for the operator to place the sample test box 200 on the loading seat 10. After the sample test box 200 is placed, the push drive assembly drives the sliding rod 311 to slide from the front end of the push guide section 211 to the rear end of the push guide section 211, so that... The sliding rod 311 moves the loading seat 10 and the sample detection box 200 into the frame 20 via the connecting plate 31. Then, the push drive assembly drives the sliding rod 311 to slide from the upper end of the lifting guide section 212 to the lower end of the lifting guide section 212, so that the sliding rod 311 drives the loading seat 10 to the detection position via the connecting plate 31. When the loading seat 10 is in the detection position, the sample detection box 200 placed on the loading seat 10 can dock with the detection device set in the frame 20, thereby amplifying and detecting the sample to be tested in the sample detection box 200.

[0065] In the pushing device of this embodiment, the pushing drive mechanism 30 can drive the loading seat 10 to move relative to the frame 20 to the loading position, so that the operator can place the sample detection box 200 on the loading seat 10 without the operator having to put their hands into the frame 20, thus preventing the introduction of impurities and contamination of the sample. The pushing drive mechanism 30 can also drive the loading seat 10 to move along the extension direction of the guide groove 21 to the detection position. The guide groove 21 and the sliding rod 311 slide together to guide the movement of the loading seat 10, so that the loading seat 10 can drive the sample detection box 200 to automatically align, effectively preventing the sample detection box 200 from shifting, tilting or misaligning, ensuring uniform amplification of the sample to be tested, and improving the detection sensitivity and accuracy of the detection results.

[0066] In this embodiment of the invention, the push drive assembly includes a swing arm 32 and a push drive member 33. The swing arm 32 is swayably disposed on the side plate 22, and a sliding groove 321 is provided on the swing arm 32. The sliding rod 311 can slide through the sliding groove 321 and extend into the guide groove 21. The push drive member 33 is used to drive the swing arm 32 to swing, so that the swing arm 32 drives the sliding rod 311 to slide from the end of the push guide section 211 away from the lifting guide section 212 to the lower end of the lifting guide section 212.

[0067] As shown in Figures 1 to 5, the push drive 33 is driven to one end of the swing rod 32 to drive the swing rod 32 to swing. The swing rod 32 has a sliding groove 321. The sliding rod 311 passes through the sliding groove 321 and the guide groove 21 in sequence, and the sliding rod 311 slides in cooperation with the sliding groove 321 and the guide groove 21 respectively. When the sample detection box 200 needs to be placed, the push drive 33 drives the swing rod 32 to swing forward. The swing rod 32 drives the sliding rod 311 in the sliding groove 321 to slide to the front end of the push guide section 211, so that the sliding rod 311 drives the loading seat 10 to the loading position through the connecting plate 31, so that the operator can place the sample detection box 200 on the loading seat 10. After the sample detection box 200 is placed, the push drive 33 drives the swing rod 32 to swing backward. The swing rod 32 drives the sliding rod 311 in the sliding groove 321 to move backward from the push guide section 211. The front end of section 211 slides to the lower end of lifting guide section 212, so that the sliding rod 311 drives the loading seat 10 to move to the detection position through the connecting plate 31. The loading seat 10 drives the sample detection box 200 to move, realizing the automatic alignment of the sample detection box 200, effectively preventing the sample detection box 200 from shifting, tilting or inaccurately aligning. The swing rod 32 drives the sliding rod 311 to slide along the guide groove 21. The sliding cooperation between the sliding rod 311 and the guide groove 21 plays the role of guiding the movement of the loading seat 10. The alignment is accurate and reliable. In addition, the swing rod 32 is provided with a groove 321 for the sliding rod 311 to slide. The groove 321 plays the role of avoiding the sliding rod 311, ensuring that the sliding rod 311 can slide along the extension direction of the guide groove 21. The structure is ingeniously designed, reducing the number of driving parts and transmission parts, and improving the movement stability and smoothness of the loading seat 10.

[0068] Furthermore, as shown in Figures 1 to 4, a plurality of guide rollers 312 arranged in sequence are sleeved on the sliding rod 311. The guide rollers 312 are used to slide in cooperation with the sliding groove 321 or the guide groove 21 to improve the smoothness of the movement of the sliding rod 311 in the sliding groove 321 and the guide groove 21. The push drive 33 can be a motor in the prior art. The output shaft of the motor passes through the side plate 22. One end of the swing rod 32 is driven and connected to the output shaft of the motor. The swing rod 32 is located between the motor and the side plate 22, so that the push drive 33 can drive the swing rod 32 to swing relative to the side plate 22.

[0069] In this embodiment of the invention, the pushing device further includes a guide assembly 40, which includes a pushing moving plate 41 and a lifting moving plate 42. The pushing moving plate 41 is disposed on the loading seat 10, and a first guide rail 411 extending laterally is provided on the side of the pushing moving plate 41 facing away from the loading seat 10. The first guide rail 411 is slidably engaged with the lifting moving plate 42. A second guide rail 421 extending vertically is provided on the side of the lifting moving plate 42 facing away from the first guide rail 411. The second guide rail 421 is slidably engaged with the side plate 22.

[0070] As shown in Figures 1 to 4, the push-moving plate 41 is connected to the loading seat 10, and the connecting plate 31 is connected to the loading seat 10 through the push-moving plate 41, so that the sliding rod 311 can sequentially drive the connecting plate 31, the push-moving plate 41, and the loading seat 10 to move. The push-moving plate 41 is provided with a first guide rail 411 that slides with the lifting moving plate 42, so that the loading seat 10 can drive the push-moving plate 41 and the first guide rail 411 to slide relative to the lifting moving plate 42 in the front-back direction. The lifting moving plate 42 is provided with a second guide rail 421 that slides with the side plate 22, so that the loading seat 10 can drive the lifting moving plate 42 and the second guide rail 421 to slide relative to the side plate 22 in the up-down direction through the push-moving plate 41 and the first guide rail 411, thereby improving the smoothness of the movement of the loading seat 10.

[0071] Furthermore, the guide assembly 40 also includes a first slider 43, which is slidably disposed on the first guide rail 411 and connected to the lifting moving plate 42; and the guide assembly 40 also includes a second slider 44, which is slidably disposed on the second guide rail 421 and connected to the side plate 22. As shown in Figures 1 to 4, the first slider 43 is disposed on the side of the lifting moving plate 42 facing the first guide rail 411 and is slidably engaged with the first guide rail 411, and the second slider 44 is disposed on the side of the side plate 22 facing the second guide rail 421 and is slidably engaged with the second guide rail 421, thus guiding the movement of the loading seat 10, improving the alignment accuracy of the sample detection box 200 and the smoothness of the movement of the loading seat 10.

[0072] In a preferred embodiment of the present invention, as shown in Figures 1 to 4, the number of guide components 40 is set to two, and the two guide components 40 are respectively disposed on the left and right sides of the loading seat 10, which improves the installation stability and smooth movement of the loading seat 10. Furthermore, the number of side plates 22 is consistent with the number of guide components 40 and is set one-to-one. The guide groove 21 is opened on one of the side plates 22, and the push drive component 33 is disposed between the two side plates 22.

[0073] In this embodiment of the invention, the frame 20 further includes a base plate 23 and a vertical plate 24. The side plates 22 and the vertical plate 24 are spaced apart on the base plate 23. The pushing device further includes a temperature control component 50, which includes a heat sink 51 and a heating seat 52. The heat sink 51 is supported on the upper end of the vertical plate 24. The heating seat 52 is located on the upper side of the heat sink 51. The heating seat 52 has a heating element 521 inside and a placement hole 522 is opened on the heating seat 52. A clearance space 60 is formed on the lower side of the loading seat 10 for the heating seat 52 to extend into. When the loading seat 10 is moved to the detection position, the heating seat 52 extends into the clearance space 60 and supports the loading seat 10. The reaction tube 201 of the sample detection box 200 extends into the placement hole 522.

[0074] As shown in Figures 2, 5, 6 and 8, two side plates 22 are respectively disposed at the left and right ends of the base plate 23. The number of upright plates 24 is set to two, which are spaced apart on the base plate 23 in the left and right direction and located between the two side plates 22. The two ends of the heat sink 51 are respectively connected to the two upright plates 24 so that the two upright plates 24 cooperate to support the heat sink 51. The heating seat 52 is disposed on the heat sink 51. The heating seat 52 has a placement hole 522 and a heating element 521 is disposed inside the heating seat 52. The detection device of the sample detection equipment is connected to the heating seat 52.

[0075] When the loading seat 10 moves to the detection position, the heating seat 52 extends into the clearance space 60 under the loading seat 10 to support the loading seat 10. The reaction tube 201 of the sample detection box 200 passes through the loading seat 10 and extends into the placement hole 522. The reaction tube 201 contains the sample to be tested. The heating element 521 can heat the reaction tube 201, and after heating, the heat can be conducted from the heating element 521 to the heat dissipation seat 51 for heat dissipation, realizing the temperature rise and fall treatment of the sample to be tested in the reaction tube 201. The detection device is connected to the heating seat 52, and the detection device can directly detect the sample to be tested after processing. That is, when the push drive mechanism 30 drives the loading seat 10 to move to the detection position, the reaction tube 201 of the sample detection box 200 extends into the placement hole 522, realizing the automatic alignment of the sample detection box 200. The temperature control component 50 can perform temperature rise and fall treatment of the reaction tube 201, and the detection device can detect the reaction tube 201. The alignment is accurate and reliable, improving the accuracy of the detection results.

[0076] Furthermore, the heating base 52 includes a heat-conducting plate 523, a placement cylinder 524, and a cover 525. The heating element 521 and the heat-conducting plate 523 are stacked on the heat dissipation base 51 from bottom to top. The placement cylinder 524 is located on the upper side of the heat-conducting plate 523. The cover 525 covers the outside of the placement cylinder 524. The placement hole 522 is opened on the cover 525 and communicates with the placement cylinder 524. When the loading base 10 moves to the detection position, the reaction tube 201 passes through the placement hole 522 and extends into the placement cylinder 524.

[0077] As shown in Figures 6 and 7, the sample detection box 200 has multiple reaction tubes 201 arranged in sequence. Multiple placement holes 522 are provided, each corresponding to one of the multiple reaction tubes 201. The number of placement cylinders 524 is the same as the number of placement holes 522 and they are arranged in a one-to-one correspondence. The optical fiber of the detection device can extend into the placement cylinder 524 to detect the reaction tubes 201. When the loading seat 10 moves to the detection position, the reaction tubes 201 pass through the placement holes 522 from the lower end of the loading seat 10 and extend into the placement cylinder 524. The heat generated by the heating element 521 is conducted to the placement cylinder through the heat-conducting plate 523. The heating element 524 heats the reaction tube 201. After heating, the heat is conducted from the heating element 521 to the heat sink 51 for heat dissipation, thus achieving the temperature rise and fall treatment of the sample to be tested in the reaction tube 201. The optical fiber of the detection device extends into the placement cylinder 524 to directly detect the sample to be tested after processing, realizing the automatic alignment of the sample detection box 200. This effectively prevents the sample detection box 200 from shifting, tilting, or being inaccurately aligned. Moreover, there are multiple reaction tubes 201, placement holes 522, and placement cylinders 524, enabling simultaneous detection of multiple reaction tubes 201, which has the advantages of high throughput and high efficiency.

[0078] In this embodiment of the invention, the heat sink 51 includes a heat sink 511 and a plurality of heat sink fins 512. The heat sink 511 is supported on the upper end of the upright plate 24, the heating seat 52 is disposed on the upper side of the heat sink 511, and the plurality of heat sink fins 512 are spaced apart on the lower side of the heat sink 511. As shown in Figures 6 and 7, the heat sink 511 is connected to the upright plate 24. The side of the heat sink 511 facing away from the heating seat 52 is provided with a plurality of heat sink fins 512, and the plurality of heat sink fins 512 are spaced apart on the heat sink 511, so that the heat generated by the heating element 521 can be dispersed and conducted to the plurality of heat sink fins 512 through the heat sink 511, thereby accelerating the heat dissipation rate, improving the cooling rate, and realizing the rapid heating and cooling cycle of the reaction tube 201.

[0079] In this embodiment of the invention, the temperature control component 50 further includes a heat-conducting seat 53 and a cooling fan 54. The heat-conducting seat 53 is disposed between the heat sink 51 and the cooling fan 54, and a heat-conducting channel 531 is formed within the heat-conducting seat 53. The two ends of the heat-conducting channel 531 are respectively disposed one-to-one with the heat sink 51 and the cooling fan 54. As shown in Figures 2 and 6, the heat sink 51, the heat-conducting seat 53, and the cooling fan 54 are all disposed between two side plates 22. A heat-conducting channel 531 is formed within the heat-conducting seat 53. One end of the heat-conducting channel 531 is disposed with respect to the heat sink 51, and the other end of the heat-conducting channel 531 is disposed with respect to the cooling fan 54. A heating seat 52 is provided on the upper side of the heat sink 51. The heating element 521 in the heating seat 52 heats the reaction tube 201, causing the reaction tube 201 to heat up rapidly. When the reaction tube 201 has finished heating, the heating element 521 stops heating, and the heat on the reaction tube 201 and the heating element 521 can be quickly conducted to the heat sink 51 for heat dissipation. The fan 54 is activated to allow the air in the heat conduction channel 531 to flow rapidly, thereby quickly transferring the heat absorbed on the heat sink 51 to the heat conduction channel 531. The hot air in the heat conduction channel 531 flows along the extension direction of the heat conduction channel 531 and releases heat during the flow. The heat conduction and dissipation speed is fast, effectively preventing heat accumulation on the reaction tube 201 and achieving rapid cooling of the reaction tube 201. The push drive mechanism 30 drives the loading seat 10 to move to the detection position, allowing the reaction tube 201 to pass through the placement hole 522 and extend into the placement cylinder 524, realizing automatic alignment of the sample detection box 200. The alignment is accurate and reliable.

[0080] Furthermore, the loading seat 10 is provided with a placement groove 11 and a limiting hole 12. The placement groove 11 is used for placing the sample detection box 200, and the limiting hole 12 is used for the reaction tube 201 of the sample detection box 200 to pass through. As shown in Figures 8 and 9, the sample detection box 200 has multiple reaction tubes 201 arranged in sequence, and multiple limiting holes 12 are provided, each for a corresponding reaction tube 201 to pass through. All limiting holes 12 are located in the placement groove 11. When the loading seat 10 is moved to the loading position, the operator can place the sample detection box 200 in the placement groove 11, so that the multiple reaction tubes 201 pass through the multiple limiting holes 12 one by one. When the loading seat 10 is moved to the detection position, the multiple limiting holes 12 are aligned with the multiple placement holes 522 one by one, so that the reaction tubes 201 passing through the limiting holes 12 can pass through the placement holes 522 and extend into the placement cylinder 524. The limiting holes 12 restrict the movement of the reaction tubes 201 and position the reaction tubes 201, thus realizing the alignment and installation of the sample detection box 200.

[0081] In this embodiment of the invention, the loading seat 10 includes a seat body 13 and a support platform 14. The seat body 13 is located at one end of the connecting plate 31, and a placement groove 11 is formed on the seat body 13. A first mounting port 131 is formed on the seat body 13. The support platform 14 includes a connecting part 141 and a support part 142. The connecting part 141 is located at the first mounting port 131 and connected to the seat body 13. The support part 142 protrudes upward and is used to support the sample detection box 200. A limiting hole 12 is formed on the support part 142.

[0082] As shown in Figures 8 to 10, the base body 13 has a placement slot 11 for placing the sample detection box 200 and a first mounting port 131 communicating with the placement slot 11. The support platform 14 is located at the first mounting port 131. The support platform 14 includes a connecting part 141 connected to the base body 13 and a support part 142 protruding upward from the connecting part 141. The support part 142 has a limiting hole 12, which allows the reaction tube 201 of the sample detection box 200 to pass through the limiting hole 12. The limiting hole 12 restricts the movement of the reaction tube 201 and positions the reaction tube 201. The support part 142 supports the lower side of the sample detection box 200, and the lower side of the support part 142 is used to avoid the heating seat 52. When the loading seat 10 moves to the detection position, the reaction tube 201 passing through the limiting hole 12 can be aligned and extended into the heating seat 52 for heating and cooling treatment and detection, which improves the reliability of the alignment installation of the sample detection box 200.

[0083] In this embodiment of the invention, the loading seat 10 further includes a support plate 15, a heating block 16 and a heat-conducting block 17. A first mounting groove 132 is provided on the bottom wall of the placement groove 11. The support plate 15 is disposed in the first mounting groove 132 and has a second mounting opening 151. The heating block 16 is disposed at the second mounting opening 151. The heat-conducting block 17 is disposed on the heating block 16 and is used to fit with the sample detection box 200.

[0084] As shown in Figures 8 to 10, a support plate 15 is provided in the first mounting groove 132. The support plate 15 is used to support the sample detection box 200. A second mounting port 151 is provided on the support plate 15. A heating block 16 is provided at the second mounting port 151. A heat-conducting block 17 is provided on the heating block 16. The heat generated by the heating block 16 can be conducted to the sample detection box 200 through the heat-conducting block 17 to heat the sample in the sample detection box 200, thereby improving the structural integration. Furthermore, in a preferred embodiment of the present invention, both the heating element 521 and the heating block 16 can be heating elements that can generate heat, such as thermoelectric semiconductor heating patches or Peltiers in the prior art.

[0085] In this embodiment of the invention, the loading base 10 further includes a panel 18, which is disposed on the base body 13 and located above the support portion 142. The panel 18 has a limiting opening 181 for the sample detection box 200 to pass through. The placement groove 11 and the limiting hole 12 are both connected to the limiting opening 181. As shown in Figures 8 to 10, the panel 18 is located above the base body 13 and the support portion 142, and the panel 18 has a limiting opening 181. The sample detection box 200 can pass through the limiting opening 181 and be placed in the placement groove 11, and the reaction tube 201 can pass through the limiting opening 181 and extend into the limiting hole 12. The limiting opening 181 further restricts the movement of the sample detection box 200, effectively preventing the sample detection box 200 from shifting or tilting.

[0086] In this embodiment of the invention, as shown in Figures 8 to 10, the loading base 10 is provided with spaced ultrasonic clearance holes 133 and magnetic clearance holes 134. The sample detection device also includes an ultrasonic processing device and a magnetic processing device disposed on the base plate 23. The ultrasonic clearance holes 133 are used for the ultrasonic head of the ultrasonic processing device to pass through, so that the ultrasonic head can abut against the sample detection box 200 and perform ultrasonic processing on the sample in the sample detection box 200. The magnetic clearance holes 134 are used for the magnetic block of the magnetic processing device to pass through, so that the magnetic block can abut against the sample detection box 200 and perform magnetic processing on the sample in the sample detection box 200. The structure has high integration and improves space utilization.
