[0045] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0046] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0047] A gene detection device, comprising:

[0048] Test tube 2, refer to the attached Figure 1 , test tube 2 is used to hold the gene solution;

[0049] Base 1, see attached Figure 1 、 2 7. A rotating mechanism for driving the test tube 2 to rotate is installed on the top of the base 1. The rotating mechanism includes a turntable 4. A plurality of placement holes 5 are opened equidistantly in the circumferential direction on the upper surface of the turntable 4. There are four placement holes 5, and the test tube 2 can be inserted into the placement holes 5;

[0050] Fluorescent agent adding mechanism, refer to the attached Figure 1 , a fluorescent agent adding mechanism is installed on the top of the base 1, and the fluorescent agent adding mechanism is used to add a fluorescent agent into the test tube 2 to make the gene solution generate a fluorescent signal;

[0051] Refer to the attached Figure 1 、 2 , 3, 5, 6 and 8, multiple clamping mechanisms, the clamping mechanisms are used to clamp the outside of the test tube 2, multiple clamping mechanisms are installed at the bottom of the turntable 4, and are correspondingly installed at each placement hole 5, and a rotating component and a lifting component are installed between the clamping mechanism and the base 1;

[0052] The rotating assembly and the clamping mechanism form a transmission fit to enable the clamping mechanism to rotate;

[0053] The lifting assembly and the clamping mechanism form a transmission cooperation, so that the lifting assembly can still lift the clamping mechanism to a certain height after locking the clamping mechanism;

[0054] Refer to the attached Figure 1 and 2 A driving assembly is installed on the base 1, and the driving assembly includes a stepper motor 30 fixedly installed at the bottom end of the base 1. The output end of the stepper motor 30 passes through the top end of the base 1 and is fixedly installed with a driving shaft 3. The top end of the driving shaft 3 is fixedly installed with the rotation center of the turntable 4.

[0055] When in use, the test tube 2 containing the gene solution is placed into the placement hole 5 corresponding to the trapezoidal lifting block 23, and the bottom end of the test tube 2 is passed through the sleeve 8 so that the bottom end of the test tube 2 falls to the top of the trapezoidal lifting block 23, completing the placement of the test tube 2.

[0056] Refer to the attached Figure 1 、 2 and 7. In this embodiment, the fluorescent agent adding mechanism includes:

[0057] An L-shaped plate 26 is fixedly mounted on the top of the base 1. A fluorescent agent storage cylinder 27 is fixedly mounted on the top of the L-shaped plate 26. A discharge pipe 28 communicating with the interior of the fluorescent agent storage cylinder 27 is fixedly mounted on the bottom of the fluorescent agent storage cylinder 27. A solenoid valve 29 is mounted on the discharge pipe 28.

[0058] A weight detection unit, the weight detection unit is electrically connected to the solenoid valve 29;

[0059] The weight detection unit includes:

[0060] The weight sensor 24 is embedded in the top of the base 1 , and the weight sensor 24 corresponds to the installation position of the fluorescent agent storage cylinder 27 .

[0061] During use, the output end of the stepper motor 30 drives the turntable 4 to rotate through the drive shaft 3, so that the turntable 4 drives the test tube 2 to rotate 90 degrees toward the side of the fluorescent agent adding mechanism through the placement hole 5 and the sleeve 8, so that the bottom end of the test tube 2 slowly descends to the base 1 along the side hypotenuse of the trapezoidal lifting block 23 until it moves to the weight sensor 24, so that the weight sensor 24 weighs the gene solution in the test tube 2 (the weight of the test tube 2 used is weighed in advance, and the weight weighed by the weight sensor 24 is the weight of the test tube 2 minus the tare weight, so that the weight of the gene solution can be directly obtained). The weight of the gene solution weighed by the weight sensor 24 opens the solenoid valve 29 through the external controller, so that the solenoid valve 29 controls the fluorescent agent storage cylinder 27 to discharge a corresponding amount of fluorescent agent into the test tube 2, so as to ensure the ratio of fluorescent agent to gene solution, so that the gene solution can produce a stable fluorescent signal, thereby reducing subsequent detection errors.

[0062] Refer to the attached Figure 3-6 In this embodiment, the clamping mechanism includes:

[0063] Two support rods 6 are fixedly mounted on the bottom of the turntable 4, and the two support rods 6 are arranged on both sides of the placement hole 5. A support ring 7 is fixedly mounted on the bottom end of the two support rods 6. A sleeve 8 is movably mounted inside the support ring 7. The sleeve 8 and the placement hole 5 are arranged on the same axis so that the test tube 2 can vertically pass through the placement hole 5 and the sleeve 8. The test tube 2 can be freely inserted into the sleeve 8. A plurality of arc-shaped elastic splints 9 are evenly fixedly mounted on the top circumferential direction of the sleeve 8. The plurality of arc-shaped elastic splints 9 are arranged in an outwardly expanding trumpet shape.

[0064] The lifting ring 10 has a locking ring 11 rotatably mounted on its inner wall. Both the locking ring 11 and the lifting ring 10 are sleeved on the outside of the sleeve 8. An annular groove is provided on the inner wall of the lifting ring 10, and the locking ring 11 is rotatably mounted in the annular groove.

[0065] After the addition of the fluorescent agent is completed, the turntable 4 continues to drive the test tube 2 and the sleeve 8 to rotate toward the excitation light source 25, so that the guide column 13 installed on the lifting rod 12 moves from the smooth section groove 141 to the lifting section groove 142, so that the guide column 13 can lift the lifting ring 10 upward through the lifting rod 12, so that the lifting ring 10 drives the locking ring 11 to move upward. When the guide column 13 moves to the front half position of the lifting section groove 142, the retaining ring 31 installed at the bottom end of the sleeve 8 is located below the arc baffle 21. When the locking ring 11 moves upward, the multiple arc-shaped elastic splints 9 will be pushed toward the test tube 2, so that the multiple arc-shaped elastic splints 9 can clamp the test tube 2, so that the sleeve 8 and the test tube 2 can be driven to rotate by the rotating assembly later, so that the gene solution in the test tube 2 is mixed with the added fluorescent agent, ensuring that the gene solution produces a uniform fluorescent signal.

[0066] Refer to the attached Figure 3 、 5 and 7. In this embodiment, the rotating assembly includes:

[0067] The driven gear ring 15 is sleeved on the outside of the sleeve 8. A plurality of limit blocks 16 are fixedly installed on the inner wall of the driven gear ring 15 at equal distances in the circumferential direction. A plurality of limit grooves 17 matching the limit blocks 16 are opened at equal distances in the circumferential direction of the outer periphery of the sleeve 8. The limit blocks 16 are slidably installed on the inner walls of the limit grooves 17. By cooperating with the limit blocks 16 and the limit grooves 17, it is possible to ensure that the driven gear ring 15 drives the sleeve 8 to rotate while the sleeve 8 can also move up and down independently. The outer surface of the support rod 6 is fixedly installed. A limit plate 22 is provided, and the driven ring gear 15 is installed between the limit plate 22 and the support ring 7. The limit plate 22 and the support ring 7 limit the axial direction of the driven ring gear 15 to prevent the sleeve 8 from driving the driven ring gear 15 to move when moving up and down, thereby affecting the meshing effect between the driven ring gear 15 and the incomplete active ring gear 19; the incomplete active ring gear 19, a plurality of connecting rods 18 are fixedly installed between the bottom end of the incomplete active ring gear 19 and the top end of the base 1, and the driven ring gear 15 intermittently meshes with the incomplete active ring gear 19;

[0068] After the test tube 2 is clamped by multiple arc-shaped elastic clamps 9, the driven gear ring 15 sleeved on the outside of the sleeve 8 will engage with the teeth of the incomplete active gear ring 19, so that the driven gear ring 15 can drive the test tube 2 to rotate and mix the gene solution with the added fluorescent agent.

[0069] Refer to the attached Figure 3 、 6 and 8. In this embodiment, the lifting assembly includes:

[0070] A lifting rod 12 is fixedly mounted on the outer periphery of the lifting ring 10, and the lifting rod 12 passes through the outer surface of the support ring 7 and is slidably mounted therewith. A guide post 13 is fixedly mounted on the outer surface of the end of the lifting rod 12 away from the lifting ring 10;

[0071] The guide collar 14 is fixedly mounted on the top of the base 1. A closed-loop guide groove is provided on the outer periphery of the guide collar 14. The closed-loop guide groove is composed of a smooth section groove 141, a lifting section groove 142, and a descending section groove 143 connected end to end. The arc-shaped baffle 21 is correspondingly mounted on the lifting section groove 142. The guide post 13 is slidably mounted on the inner wall of the closed-loop guide groove.

[0072] The arc-shaped baffle 21 is fixedly mounted on the inner side of the top end of the guide collar 14, and a retaining ring 31 corresponding to the arc-shaped baffle 21 is fixedly mounted on the outer periphery of the bottom end of the sleeve 8;

[0073] The stopper 20 is fixedly mounted on the outer surface of the top end of the arc-shaped elastic clamping plate 9 .

[0074] When the guide post 13 moves to the tail section position of the lifting section groove 142, the locking ring 11 abuts against the stopper 20 on the arc-shaped elastic splint 9 and cannot move up any further, so that the test tube 2 is clamped by the multiple arc-shaped elastic splints 9, and the retaining ring 31 installed at the bottom end of the sleeve 8 also leaves the bottom of the arc-shaped baffle 21. At this time, as the guide post 13 continues to move, the guide post 13 can continue to drive the sleeve 8 and the test tube 2 as a whole to continue to move upward through the lifting rod 12 and the lifting ring 10, lifting the bottom of the test tube 2 to a certain height, avoiding the bottom end of the test tube 2 from being in contact with the base 1 during rotation, avoiding wear or cracking of the bottom of the test tube 2, and extending the service life.

[0075] Refer to the attached Figure 2 and 7 In this embodiment, an excitation light source 25 (such as ultraviolet light) is embedded in the top of the base 1, and the excitation light source 25 is correspondingly installed at the lifting section groove 142 and the descending section groove 143.

[0076] While the test tube 2 rotates, the excitation light source 25 embedded in the top of the base 1 can illuminate the gene solution and fluorescent agent in the test tube 2 (the test tube 2 is made of glass to ensure light transmission), so that the excitation light source 25 excites the fluorescent marker in the gene solution, so that the presence, concentration or other characteristics of the target gene can be analyzed through the changes in the fluorescence signal using a fluorescence microscope. For amplification experiments such as PCR, the number of target genes can be calculated by the threshold value (CT value) of the fluorescence signal.

[0077] Refer to the attached Figure 2 and 7 In this embodiment, a lifting assembly is installed at the top of the base 1, and the lifting assembly includes a trapezoidal lifting block 23 fixedly installed on the top of the base 1. The trapezoidal lifting block 23 is installed corresponding to the smooth section groove 141. A sponge pad is bonded to the top of the trapezoidal lifting block 23 to cushion the bottom end of the test tube 2 after it falls to the top of the trapezoidal lifting block 23, preventing the test tube 2 from making hard contact with the top of the trapezoidal lifting block 23 and causing damage to the test tube 2.

[0078] When the guide column 13 returns to the smooth section groove 141 from the descending section groove 143, the test tube 2 is moved to the other side of the inclined edge of the trapezoidal lifting block 23, so that the bottom end of the test tube 2 will be lifted up to the top of the trapezoidal lifting block 23 along the inclined edge, so that the upper part of the test tube 2 is exposed from the top of the turntable 4, making it convenient to take the test tube 2.

[0079] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
