[0002] In the fields of modern medicine and life sciences, rapid and accurate detection of pathogens is of paramount importance for disease diagnosis, treatment, prevention and control, and public health security. Nucleic acid testing, as a crucial method for pathogen detection, has been widely applied in numerous fields, including clinical diagnosis, epidemic monitoring, and food safety testing.

[0003] In existing technologies, when using extraction and detection devices to detect pathogen nucleic acids, it is necessary to mix the pathogen nucleic acid samples to improve the accuracy of the detection results. However, traditionally, the mixing is done manually by staff, which not only increases the workload of staff but also affects the efficiency of pathogen nucleic acid detection. Utility Model Content

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a pathogen nucleic acid extraction and detection device, comprising a shell, two movable grooves formed at the bottom of the inner wall of the shell, a placement frame movably embedded between the inner surfaces of the two movable grooves, a fixing block fixedly installed at the bottom of the placement frame, a first toothed row fixedly installed on the inner surface of the fixing block, a gear fixedly installed at the bottom of the inner wall of the shell via a mounting frame, the outer surface of the gear meshing with the outer surface of the first toothed row, two limiting blocks fixedly installed at the bottom of the inner wall of the shell, a second toothed row movably inserted between the inner surfaces of the two limiting blocks, the outer surface of the second toothed row meshing with the outer surface of the gear, and a connecting rod provided on the inner surface of the second toothed row.

[0006] Preferably, a motor is fixedly installed on the bottom of the inner wall of the outer casing, and an eccentric wheel is fixedly sleeved on the output end of the motor. The motor, as a transmission device, can drive the eccentric wheel to rotate.

[0007] Preferably, the outer wall of the eccentric wheel is movably connected to the inner wall of the connecting rod, and the rotation of the eccentric wheel can drive the connecting rod to move.

[0008] Preferably, a side cover is provided on one side of the outer wall of the housing, and a sealing ring is provided on the outer wall of the side cover. The sealing ring can maintain the airtightness of the device and prevent external dust from entering and affecting the test results.

[0009] Preferably, the outer wall of the side cover is provided with a dustproof ring, and the inner wall of the outer shell is fixedly installed with a cross slide. With the action of the dustproof ring, external dust can be further prevented from entering the device.

[0010] Preferably, a telescopic rod is fixedly inserted into the inner wall of the cross slide, and a detector is fixedly installed at the telescopic end of the telescopic rod. Under the action of the cross slide and the telescopic rod, the detector can be moved to make it more convenient to detect pathogen nucleic acid samples.

[0011] Preferably, an observation window is provided on one side of the outer wall of the housing. Through the observation window, the working status of the detection device can be observed more clearly, and it is convenient for the staff to adjust it.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, when it is necessary to mix pathogen nucleic acid samples, the pathogen nucleic acid samples are first placed inside the placement rack.

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Please see Figures 1-4 This utility model provides a pathogen nucleic acid extraction and detection device, including a shell 1. Two movable grooves 8 are opened at the bottom of the inner wall of the shell 1. A placement frame 9 is movably embedded between the inner surface walls of the two movable grooves 8. A fixing block 10 is fixedly installed at the bottom of the placement frame 9. A first toothed row 11 is fixedly installed on the inner surface wall of the fixing block 10. A gear 12 is fixedly installed at the bottom of the inner wall of the shell 1 through the mounting frame, and the outer surface wall of the gear 12 meshes with the outer surface wall of the first toothed row 11. Two limiting blocks 13 are fixedly installed at the bottom of the inner wall of the shell 1. A second toothed row 14 is movably inserted between the inner surface walls of the two limiting blocks 13, and the outer surface wall of the second toothed row 14 meshes with the outer surface wall of the gear 12. A connecting rod 15 is provided on the inner surface wall of the second toothed row 14.

[0023] like Figure 3 As shown: A motor 16 is fixedly installed on the bottom of the inner wall of the outer casing 1. An eccentric wheel 17 is fixedly sleeved on the output end of the motor 16. The motor 16, as a transmission device, can drive the eccentric wheel 17 to rotate.

[0024] like Figure 3 , Figure 4 As shown: The outer wall of the eccentric wheel 17 is movably connected to the inner wall of the connecting rod 15. The rotation of the eccentric wheel 17 can drive the connecting rod 15 to move.

[0025] like Figure 2 As shown: A side cover 2 is provided on one side of the outer wall of the outer casing 1, and a sealing ring 3 is provided on the outer wall of the side cover 2. Under the action of the sealing ring 3, the airtightness of the equipment can be maintained, and external dust can be prevented from entering and affecting the test results.

[0026] like Figure 2 As shown: a dustproof ring 4 is provided on the outer wall of the side cover 2, and a cross slide 5 is fixedly installed on the inner wall of the outer shell 1. Under the action of the dustproof ring 4, external dust can be further prevented from entering the device.

[0027] like Figure 2 As shown: A telescopic rod 6 is fixedly inserted into the inner wall of the cross slide 5. A detector 7 is fixedly installed at the telescopic end of the telescopic rod 6. Under the action of the cross slide 5 and the telescopic rod 6, the detector 7 can be moved to make it more convenient to detect pathogen nucleic acid samples.

[0028] like Figures 1-3 As shown: An observation window 18 is provided on one side of the outer wall of the outer casing 1. Through the observation window 18, the working status of the detection device can be observed more clearly, and it is convenient for the staff to adjust it.

[0029] The operating method and working principle of this device are as follows: Before detecting pathogen nucleic acid, the pathogen nucleic acid sample is first placed inside the placement rack 9 under the operation of the operator, and the side cover 2 is closed. The sealing ring 3 and dustproof ring 4 effectively prevent external dust and impurities from entering the detection device. Then, under the action of the motor 16, the eccentric wheel 17 rotates. Simultaneously, under the action of the connecting rod 15 and the limiting block 13, the second gear rack 14 reciprocates. At the same time, under the action of the gear 12, the first gear rack 11 reciprocates. Under the action of the fixing block 10, the placement rack 9 reciprocates within the movable groove 8, thereby causing the pathogen nucleic acid sample placed inside the placement rack 9 to shake, ensuring the pathogen nucleic acid sample is evenly mixed. Once the pathogen nucleic acid sample is evenly mixed, the motor 16 stops working, and the placement rack 9 stops moving. The mixing of pathogen nucleic acid samples is stopped, and then the pathogen nucleic acid samples are tested. Under the action of the drive device and threaded rod inside the cross slide 5, the telescopic rod 6 and the detector 7 can be moved to the appropriate position. The telescopic rod 6 drives the detector 7 to move downward to the appropriate position to test the pathogen nucleic acid samples. During the mixing and testing of pathogen nucleic acid samples, the state of the device and pathogen nucleic acid samples can be clearly observed through the observation window 18, which allows the staff to make corresponding adjustments at any time. After the pathogen nucleic acid samples have been tested, the staff can open the side cover 2 to take out the pathogen nucleic acid samples from the placement rack 9 and place other pathogen nucleic acid samples into the placement rack 9. The above structure and method greatly improve the practicality of the detection device for testing pathogen nucleic acid samples.
