Abstract
Description
Technical Field
[0001] The present invention relates to the field of liquid phase chips, in particular to a liquid phase chip detection device. Background Art
[0002] Liquid-phase chip detection equipment is an analytical instrument used in fields such as chemistry, biology, and clinical medicine. It utilizes dual-fluorescence labeling of microspheres and liquid-dispersed laser automated detection technology to automatically perform multi-channel, high-throughput analysis of nucleic acids, enzymes, receptors, antibodies, and antigens. The core technology of the liquid-phase chip detection equipment is the patented xMAP coded microsphere system. Using unique microsphere surface chemistry, different probe molecules are labeled on the microspheres, each corresponding to a specific target molecule. When the microbeads, coupled with specific antibodies, react with proteins in the sample, biotin-labeled detection antibodies are added, and the signal is amplified by linking PE-labeled streptavidin to the biotin. During detection, the microbeads rapidly pass through the liquid flow system through a first red laser beam to identify the microbeads. A second green laser beam detects the intensity of the PE fluorescence signal. Finally, the optical signal is rapidly processed into a digital signal, which is analyzed by software to calculate the content of each protein.
[0003] However, existing liquid chip detection equipment generally uses 96-well plates or 384-well plates, and is equipped with a sampling head with 4 or 8 sampling tubes for sampling. Regardless of whether 4 or 8 sampling tubes are used, neither can be flexibly adjusted and switched, and the sampling rate cannot be conveniently adjusted.
[0004] The authorization announcement number is CN113985048B, which discloses a liquid chip detection device, which relates to the field of biochip detection technology, including a loading mechanism, a pipetting mechanism, a collection mechanism, a detection area and a detection device. The loading mechanism is used to detachably load the reagent card, the pipetting mechanism is used to transfer the sample from the sample position for accommodating the sample to the reaction position for providing a reaction site, transfer the reagent from the reagent position to the reaction position, and remove the reacted solution from the reaction position. The sample and the reagent react at the reaction position and obtain the particles to be analyzed, and the collection mechanism is used to collect the particles to be analyzed. The detection area includes a microfluidic detection area or a fixed detection area, the light source is used to irradiate the particles in the detection area, and the detection device is used to detect the light signal emitted by each particle. Due to the addition of the pipetting mechanism and the collection mechanism, the manual operation steps of the liquid chip detection equipment are reduced, which is conducive to reducing the labor intensity of the operator and reducing the errors caused by manual operation.
[0005] While the above technical solution can reduce manual operation steps, it still cannot flexibly adjust the number of sampling tubes used, nor can it flexibly switch and control them during the specific sampling process. In addition, the existing sampling tubes have the risk of dripping after sampling, which can easily cause the sampling solution to drip into other areas of the well plate and contaminate samples in other areas of the well plate. Therefore, a liquid chip detection device is proposed. Summary of the Invention

[0017] The beneficial effects of the present invention are: 1.

During the process, the electric control sampling tubes originally facing upwards are also rotated to face downwards, so that the electric control sampling tubes installed on the two rotating shafts 1 can both face downwards and be used at the same time, forming multiple electric control sampling tubes for joint sampling, thereby improving sampling efficiency. When the electric control sampling tubes installed on the two rotating shafts 1 are 180 degrees apart from each other, only the electric control sampling tube on one rotating shaft is used for sampling, which greatly facilitates the adjustment of the use of the electric control sampling tubes. 2. The technical solution of the present invention can drive the sampling frame to move upward after sampling is completed through the contraction cooperation of the upper telescopic member and the lower telescopic member, until the slide sliding in the upper frame moves upward, and the horizontal plate connected to the slide moves up to contact the top frame. At this time, the slide can be pushed downward relative to the frame, and the rack second can be driven downward. The engagement of the rack second and the gear second drives the rotation shaft second to rotate, so that the drip-proof cover can overcome the elastic force of the spring hinge and rotate to the lower side of the electric-controlled sampling tube to block the lower side of the electric-controlled sampling tube, thereby avoiding the risk of dripping and contamination of the sample liquid in the electric-controlled sampling tube; 3. The technical solution of the present invention drives the lower telescopic member and the sampling frame to the rear end of the sample chamber through the Y-axis slide rail, and controls the extension and coordination of the upper telescopic member and the lower telescopic member, so that the side seats on both sides of the sampling frame can move to the lower side of the pulling seat. After the electric-controlled sampling tube completes sampling and pipetting, the sampling frame is controlled to move upward, and the rotating plate is pulled by the pulling seat to rotate, thereby driving the lower seat to move directly below the sampling frame. At the same time, according to the rotation of the rotating seat, when the electric-controlled sampling tubes on the two rotating shafts are both facing downward, the rotating seat will not interfere with the T-shaped top plate, and the cleaning box can also be directly below the sampling frame and clean each electric-controlled sampling tube through the cleaning hole. When the electric-controlled sampling tubes on the two rotating shafts are 180 degrees to each other, only one side of the electric-controlled sampling tube is facing downward. At this time, one end of the rotating seat will interfere with the T-shaped top plate, causing the cleaning box to slide and push a row of the two cleaning holes opened on the cleaning box to directly below the sampling frame to achieve precise coordinated cleaning.

[0026] like Figures 1-8 As shown, the present invention discloses a liquid chip detection device. Compared with the first embodiment, this embodiment discloses the structure of the orientation adjustment component.
[0027] The azimuth adjustment assembly includes an x-axis slide rail 5, an upper telescopic member 6, a y-axis slide rail 7, and a lower telescopic member 8.

[0030] Example 3:
[0031] like Figures 1-8 As shown, the present invention discloses a liquid phase chip detection device. Compared with the second embodiment, this embodiment discloses the structure of the control component.
[0032] The control assembly includes a gear 15, a guide rod frame 16, a rack 17, an arc block 21, and an arc frame 23. The gear 15 is mounted on both ends of each rotating shaft 13. The guide rod frame 16 is connected to the side of the rotating seats 12 on both sides close to each other. One end of the rack 17 is slidably mounted on the outside of the guide rod frame 16, and the other end extends between the gears 15 on the two rotating shafts 13 and is meshed with the gears 15 on both sides. A spring 18 is connected between the rack 17 and the guide rod frame 16 and is mounted on the outside of the guide rod frame 16. The arc block 21 is connected to the end of the rack 17 away from the guide rod frame 16. The arc frame 23 is connected to the sampling frame 10, and the arc block 21 is slidably connected in the arc frame 23.
[0033] The arc frame 23 is an irregular arc shape, with its side end away from the rotating seat 12 and the lower end close to the rotating seat 12, so that when the rotating seat 12 rotates and drives the arc block 21 to slide therein, it can drive the rack 17 to be pushed to slide on the guide rod frame 16 and compress the spring 18. When the electric control sampling tubes 14 installed on the upper and lower rotating shafts 13 are 180 degrees apart, the arc block 21 is at the side end of the arc frame 23, and then when the rotating seat 12 is driven to rotate by the frequency conversion motor 11, it can drive the arc block 21 to slide from the side end of the arc frame 23 to the lower end. During the process, the arc block 21 will drive the rack 17 to slide, and through engagement with the gear 15, drive the electric control sampling tubes 14 installed on the two rotating shafts 13 to rotate close to each other to a state of 0 degrees and facing downward, so as to facilitate sampling and also facilitate adjustment of the number of electric control sampling tubes 14 used for specific sampling.
[0034] Furthermore, the rotating seat 12 is actually a disc with a protrusion at one end. When the two electrically controlled sampling tubes 14 on the rotating shaft 13 are at 0° to each other, the protrusion side is facing upward and is located in the sampling frame 10. When the two electrically controlled sampling tubes 14 on the rotating shaft 13 are at 180° to each other, the protrusion side is facing the side away from the orifice plate rack 4.
[0035] A guide slide 19 is provided on the rack 17, and a guide block 20 is connected to the rotating seat 12, and the guide block 20 is slidably sleeved in the guide slide 19. The rotating seats 12 on both sides are connected to the side close to each other, and the arc frame 23 is connected to the end of the connecting plates 22 on both sides that are close to each other. This arrangement allows the rack 17 to slide more stably on the rotating seat 12 when the arc block 21 pushes the rack 17 to slide.
[0036] By controlling the frequency conversion motor 11 to operate, the rotating seat 12 can be driven to rotate, so that during the rotation of the rotating seat 12, the rack 17 sliding thereon can be driven to rotate accordingly, and then the arc block 21 connected to one end of the rack 17 will slide in the arc frame 23 and come into conflict with the inner wall of the arc frame 23, so that the rack 17 slides relative to the rotating shaft 13 on both sides, and through the engagement with the gear 15, drives the electric control sampling tube 1 on both sides of the rotating shaft 13, which was originally at 180 degrees. 4 are rotated close to each other to 0°. During the process, the electric-controlled sampling tube 14 originally facing upward is also rotated to face downward, so that the electric-controlled sampling tubes 14 installed on the two rotating shafts 13 can all face downward and be used at the same time, forming multiple electric-controlled sampling tubes 14 for joint sampling, thereby improving the sampling efficiency. When the electric-controlled sampling tubes 14 installed on the rotating shafts 13 on both sides are 180° apart from each other, only the electric-controlled sampling tube 14 on the rotating shaft 13 is used for sampling, which greatly facilitates the adjustment of the use of the electric-controlled sampling tubes 14.
[0037] Example 4:
[0038] like Figures 1-8 As shown, the present invention discloses a liquid chip detection device. Compared with the third embodiment, this embodiment discloses the structure of a linkage component.
[0039] The linkage assembly includes a side seat 34, a slide rail 35, a lower slide seat 36, a slide rod frame 37, an upper slide seat 38, an electric telescopic rod 40, a T-shaped top plate 43, and a pull seat 45. The side seat 34 is connected to both sides of the sampling frame 10, the slide rail 35 is connected to the lower inner wall of the sample chamber 2, the lower slide seat 36 is slidably connected to the slide rail 35, the slide rod frame 37 is connected to the lower slide seat 36, and the upper slide seat 38 is slidably sleeved on the outer side of the slide rod frame 37, and the upper slide seat 38 is connected to the slide rod frame 37. There is a spring 39 sleeved on the outside of the slide rack 37, the electric telescopic rod 40 is connected to both sides of the upper slide 38, the cleaning box 41 is connected to the upper output end of the two electric telescopic rods 40, the T-shaped top plate 43 is connected to the side of the cleaning box 41 away from the orifice plate rack 4, and cooperates with the rotating seat 12, the pull seat 45 is slidably set in the sample chamber 2, and is rotatably connected to the lower slide seat 36 with a rotating plate 44, and the upper end surface of the side seat 34 cooperates with the lower end surface of the pull seat 45.
[0040] A plurality of cleaning holes 42 are arranged in an array on the upper end surface of the cleaning box 41. A cleaning agent nozzle, a brush and an emptying channel are installed in each cleaning hole 42. The electric-controlled sampling tube 14 is slidably inserted into the cleaning hole 42, so that each electric-controlled sampling tube 14 can be inserted into its respective cleaning hole 42 for cleaning.
[0041] Limit slide bars 46 are installed on both sides of the upper inner wall of the sample chamber 2, and the pull seat 45 is slidably sleeved on the outer side of the limit slide bar 46. A spring four 47 is connected between the pull seat 45 and the upper inner wall of the sample chamber 2, so that the pull seat 45 can slide more stably in the sample chamber 2, and in the absence of external force, the pull seat 45 will move downward under the elastic force of the spring four 47 until it contacts the lower end of the limit slide bar 46 and stops.
[0042] Specifically, when in use, the Y-axis slide rail 7 is controlled to drive the lower telescopic member 8 and the sampling frame 10 to move to the rear end of the sample chamber 2, and the upper telescopic member 6 is controlled to extend and cooperate with the lower telescopic member 8, so that the side seats 34 on both sides of the sampling frame 10 can move to the lower side of the pull seat 45. After the electronically controlled sampling tube 14 completes sampling and pipetting, the sampling frame 10 is controlled to move upward, and the rotating plate 44 is pulled to rotate by the pull seat 45, thereby driving the lower seat 36 to move to the bottom of the sampling frame 10. At the same time, according to the rotation of the rotating seat 12, when the electronically controlled sampling tubes 14 on the two rotating shafts 13 are all facing downward, the rotating seat 12 will not conflict with the T-shaped top plate 43, and the cleaning box 41 can also be in The cleaning box 41 is directly below the sampling frame 10, and each electric-controlled sampling tube 14 is cleaned through the cleaning hole 42. When the electric-controlled sampling tubes 14 on the two rotating shafts 13 are 180 degrees to each other, only the electric-controlled sampling tube 14 on one side is facing downward. At this time, one end of the rotating seat 12 will conflict with the T-shaped top plate 43, causing the cleaning box 41 to slide and push a row of the two cleaning holes 42 opened on the cleaning box 41 to directly below the sampling frame 10 to achieve precise matching cleaning, ensuring that no matter whether the electric-controlled sampling tube 14 on one rotating shaft 13 or the electric-controlled sampling tubes 14 on both rotating shafts 13 are used, efficient and precise alignment cleaning can be performed.
