Description

Technical Field

[0001] This utility model relates to the field of sample pretreatment equipment technology, and in particular to a sample pretreatment device for rapid detection of microorganisms. Background Technology

[0002] Microbial sample pretreatment typically involves steps such as heating and stirring. The purpose is to effectively promote the dissolution, dispersion, or inactivation of microorganisms, ensuring that representative sample information can be obtained in subsequent detection processes. In practice, heating and stirring during pretreatment play an important role in improving the reaction rate of samples, enhancing sample homogeneity, and reducing errors. Heating can accelerate the metabolic activities of microorganisms or promote certain chemical reactions, thereby improving detection efficiency, while stirring helps to homogenize the samples, avoid component precipitation or local concentration differences, and ensure the consistency of microbial detection.

[0003] Existing technologies, such as the utility model patent with publication number CN218290921U, disclose a rapid microbial sampling and detection device. This patent includes a test tube with an opening at the top, a sealing plug, a sampling component, and an adjustable steering component. The sealing plug is sealed and installed at the top of the test tube, and the sampling component passes through the sealing plug and extends into the test tube. This utility model, by adopting an integrated connection between the test tube and swab, ensures that the test tube and swab are stored in the same environment, avoiding contamination, and greatly reduces the time spent by staff searching for test tubes and swabs for sampling. It prevents situations where sampling cannot be carried out due to a lack of swabs or test tubes, improving the sampling efficiency of staff. Simultaneously, the integrated structure avoids confusion after swab sampling, improving sampling accuracy. With the assistance of the adjustable steering component, subsequent opening of the sealing plug and adjustment of the rotation angle are convenient, facilitating subsequent sampling and testing, and reducing the workload of staff.

[0004] The inventors discovered in daily use that in the process of detecting microbial samples, the samples need to undergo a pretreatment step of stirring and heating. The current operation method is to place the sample cup directly on the heating plate and use a stirrer to stir it. However, the sample cup is prone to shaking during the stirring process, which can cause the sample to overflow or leak, resulting in sample loss. This unstable operation not only affects the integrity of the sample, but also has an adverse effect on the reliability of the experimental process and the accuracy of the data.

[0005] This application provides another technical solution to this technical problem, aiming to provide those skilled in the art with multiple options for solving the problem. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies in the detection of microbial samples, which require a pretreatment step of stirring and heating. The current method involves placing the sample cup directly on a heating plate and stirring it with a stirrer. However, the sample cup is prone to shaking during stirring, leading to sample overflow or leakage and thus sample loss. This unstable operation not only affects the integrity of the sample but also has an adverse impact on the reliability of the experimental process and the accuracy of the data. Therefore, this invention proposes a rapid microbial detection sample pretreatment device.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a microbial rapid detection sample pretreatment device, comprising a heater, a heating plate, and an auxiliary structure.

[0013] Preferably, a soft pad, which is a rubber pad, is fixedly connected to one side of the limiting frame.

[0014] The effect achieved by the above components is that the soft pad can prevent the limiting frame from directly contacting the sample cup, thereby preventing the sample cup from being worn.

[0015] Preferably, the upper surface of the heater is provided with an auxiliary structure, the auxiliary structure including a plurality of positioning seats, the plurality of positioning seats being fixedly connected to the heater, a connecting block being slidably connected to the inner wall of the positioning seat, the connecting block being fixedly connected to the heating plate, two telescopic rods being fixedly connected to one side of the positioning seat, one end of the plurality of telescopic rods being fixedly connected to the same auxiliary plate, a second spring being sleeved on the arc surface of the telescopic rod, the two ends of the second spring being fixedly connected to the positioning seat and the auxiliary plate respectively, and two inserts being fixedly connected to one side of the auxiliary plate, the inserts being slidably connected to the positioning seat and the connecting block respectively.

[0016] The effect achieved by the above components is that by setting up auxiliary structures, the heating plate can be easily replaced or maintained, avoiding wear and tear on the integrated heating plate after long-term use, thereby improving the heating efficiency of the heating plate.

[0017] Preferably, the second spring has a bellows sleeved on its arc surface, and the two ends of the bellows are fixedly connected to the positioning seat and the auxiliary plate, respectively.

[0018] The effect achieved by the above components is that the bellows can protect the second spring and prevent foreign objects from getting stuck in the second spring during use.

[0019] Preferably, positioning frames are fixedly connected to both sides of the heating plate, and connecting blocks are slidably connected to the inner walls of the positioning frames, with the connecting blocks and heaters being fixedly connected.

[0020] The effect achieved by the above components is that the positioning frame and connecting block can fix the heating plate more stably, and prevent the heating plate from shifting during the fixing process.

It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims.

[0032] Reference Figure 1As shown, this utility model provides a technical solution: a microbial rapid detection sample pretreatment device, including a heater 1, a heating plate 3 and an auxiliary structure 7. A control button 2 is installed on one side of the heater 1. The upper surface of the heater 1 is fixed to the heating plate 3 by means of the auxiliary structure 7. A sample cup 4 is placed on the upper surface of the heating plate 3. A stirrer 5 is installed on one side of the heater 1. An adjustment structure 6 is provided on the upper surface of the heating plate 3. An auxiliary structure 7 is provided on the upper surface of the heater 1.

[0033] The specific settings and functions of its adjustment structure 6 and auxiliary structure 7 will be discussed below.

[0034] Reference Figure 2 , Figure 3 As shown in this embodiment: the adjustment structure 6 includes a circular frame 601, which is fixedly connected to the heating plate 3. A fixing groove 602 is provided on the inner wall of the circular frame 601, and the fixing groove 602 is slidably connected to the sample cup 4. Two positioning blocks 603 are slidably connected to the inner wall of the circular frame 601. Limit frames 604 are fixedly connected to the sides of the two positioning blocks 603 that are close to each other. Two limiting rods 605 are fixedly connected to one side of the limiting frame 604, and the limiting rods 605 are slidably connected to the circular frame 601. Two positioning rods 606 are fixedly connected to the upper surface of the heating plate 3. A push block 607 is slidably connected to the arc surface of the positioning rods 606. The same pull ring 608 is slidably connected to the arc surfaces of the two positioning rods 606, and the pull ring 608 is fixedly connected to the push block 607. A first spring 609 is sleeved on the arc surface of the positioning rods 606, and both ends of the first spring 609 are fixedly connected to the pull ring 608 and the heating plate 3, respectively. By setting the adjustment structure 6, the sample cup 4 can be easily adjusted. The fixed design prevents sample overflow or leakage due to shaking during stirring, thus ensuring the stability and safety of the sample during stirring and significantly improving the accuracy of operation. The pull ring 608 has anti-slip textures 610 evenly distributed on its arc surface, increasing friction and preventing slippage when moving it. A pulley 611 is rotatably connected to one side of the positioning block 603, with its arc surface slidably connected to the push block 607. The pulley 611 reduces friction between the positioning block 603 and the push block 607, allowing for smoother movement of the positioning block 603. A soft pad 612, made of rubber, is fixedly connected to one side of the limiting frame 604, preventing direct contact between the limiting frame 604 and the sample cup 4, thus preventing wear on the sample cup 4.

[0035] Reference Figure 4 , Figure 5 and Figure 6As shown in this embodiment: the auxiliary structure 7 includes several positioning seats 72, which are fixedly connected to the heater 1. A connecting block 71 is slidably connected to the inner wall of each positioning seat 72, and the connecting block 71 is fixedly connected to the heating plate 3. Two telescopic rods 73 are fixedly connected to one side of each positioning seat 72. One end of each telescopic rod 73 is fixedly connected to the same auxiliary plate 74. A second spring 75 is sleeved on the arc surface of each telescopic rod 73. The two ends of the second spring 75 are fixedly connected to the positioning seat 72 and the auxiliary plate 74, respectively. Two inserts 76 are fixedly connected to one side of the auxiliary plate 74, and the inserts 76 are slidably connected to the positioning seat 72 and the connecting block 71, respectively. By setting the auxiliary structure 7, the heating plate 3 can be easily adjusted. Replacement or maintenance is required to prevent wear and tear on the integrated heating plate 3 during prolonged use, thereby improving the heating efficiency of the heating plate 3. A corrugated tube 77 is fitted onto the arc surface of the second spring 75. The two ends of the corrugated tube 77 are fixedly connected to the positioning seat 72 and the auxiliary plate 74, respectively. The corrugated tube 77 can protect the second spring 75 and prevent foreign objects from getting stuck in it during use. Positioning frames 78 are fixedly connected to both sides of the heating plate 3. A connecting block 79 is slidably connected to the inner wall of the positioning frame 78. The connecting block 79 is fixedly connected to the heater 1. The positioning frame 78 and the connecting block 79 can make the heating plate 3 more stable and prevent the heating plate 3 from shifting during the fixing process.

[0036] Detailed Instructions for Use: By adjusting the structure 6, first move the pull ring 608 using the anti-slip texture 610. This causes the pull ring 608 to move the push block 607 on the positioning rod 606. Simultaneously, the pull ring 608 moves, causing the first spring 609 to retract. Then, place the sample cup 4 into the fixing groove 602 of the circular frame 601. Release the pull ring 608. As it releases, the first spring 609 moves the pull ring 608, which in turn moves the push block 607 on the positioning rod 606. Simultaneously, the push block 607 pushes the positioning block 603 inside the circular frame 601. The movement of the positioning block 603 causes the limiting frame 604 to move, and the limiting frame 604 then... The limiting rod 605 moves inside the circular frame 601 until the limiting frame 604 is fixed to the sample cup 4. Then, the sample can be poured into the sample cup 4, and the stirrer 5 is started to stir. Pressing the control button 2 on the side of the heater 1 will heat the sample cup 4 with the heating plate 3. The anti-slip texture 610 can increase the friction of the pull ring 608 and prevent the person's hand from slipping when moving the pull ring 608. The pulley 611 can reduce the friction between the positioning block 603 and the push block 607, so that the positioning block 603 moves more smoothly. The soft pad 612 can prevent the limiting frame 604 from directly contacting the sample cup 4, thus preventing the sample cup 4 from being worn.

[0037] By setting up the auxiliary structure 7, the second spring 75 and the telescopic rod 73 are first stretched by the auxiliary plate 74. While the auxiliary plate 74 is moving, it will also move the insertion block 76, so that the insertion block 76 is separated from the connecting block 71 and the positioning seat 72. At this time, the heating plate 3 can be replaced or maintained. The corrugated pipe 77 can protect the second spring 75 and prevent foreign objects from getting stuck in the second spring 75 during use. The positioning frame 78 and the connecting block 79 can make the heating plate 3 more stable and prevent the heating plate 3 from shifting during the fixing process.
