Description

Technical Field

[0001] This utility model relates to the field of medical testing technology, and in particular to a reagent tray for a thermostatic fluorescence amplification instrument with a desiccant seal. Background Technology

[0002] Many reagents used in isothermal fluorescence amplification are extremely sensitive to humidity. The presence of water molecules can interfere with the structure and activity of biomolecules in the reagents, such as causing hydrolysis and denaturation of nucleic acid molecules, affecting the catalytic activity of enzymes, and thus reducing the efficiency and specificity of the amplification reaction. Once the reagents become damp, their performance will decline rapidly, potentially leading to false negative or false positive results, seriously affecting the reliability and reproducibility of the experiment.

[0003] Traditional environments struggle to maintain dryness: In conventional laboratory settings, humidity is difficult to control precisely and consistently, especially in areas or seasons with high humidity levels where moisture in the air can easily seep into reagent storage containers. Traditional reagent trays lack effective moisture-proofing measures; even with simple sealing, they cannot prevent the intrusion of trace amounts of moisture, leaving reagents at risk of becoming damp after prolonged use.

[0004] With the widespread application of isothermal fluorescence amplification technology in clinical diagnosis, disease screening, scientific research, and other fields, higher requirements are being placed on the drying performance of instrument reagent trays. However, existing drying solutions are often disconnected from the overall instrument design. Either the drying device is too large, occupying too much instrument space and affecting the instrument's compactness, or it cannot work in conjunction with the instrument's isothermal system, failing to maintain a suitable temperature while ensuring a dry environment. As a result, the overall performance of the instrument cannot meet the growing experimental demands. Therefore, a reagent tray for isothermal fluorescence amplification instruments with a desiccant seal is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this invention provides a reagent tray for a thermostatic fluorescence amplification instrument with a desiccant seal, aiming to improve the problem that some existing devices cannot achieve the desired drying effect.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A reagent tray for a thermostatic fluorescence amplification instrument with a desiccant seal includes a supporting protective shell. An insulation mechanism is fixedly connected inside the supporting protective shell. A drying outer shell is fixedly connected to the top of the supporting protective shell. An insulation mechanism is fixedly connected to the top of the insulation mechanism. The drying outer shell includes a sealing connecting ring and a sealing top shell. A drying assembly for drying is fixedly connected to the bottom of the sealing connecting ring. The drying assembly includes a sealing connecting inner shell. A sealing connecting inner shell is fixedly connected to the bottom of the sealing connecting ring. An insulation outer shell is fixedly connected to the outside of the sealing connecting ring.

[0008] As a further description of the above technical solution:

[0009] The heat preservation mechanism includes an electromagnetic heater, and a connecting heat-conducting plate is fixedly connected to the top of the electromagnetic heater. A heat dissipation fin is fixedly connected to the top of the connecting heat-conducting plate.

[0010] As a further description of the above technical solution:

[0011] Multiple water-absorbing plates are fixedly connected inside the sealed connecting inner shell, and the top of the water-absorbing plates is fixedly connected to the bottom of the sealed connecting ring.

[0012] As a further description of the above technical solution:

[0013] A sealing rubber ring is slidably connected to the bottom of the sealing top shell, and a heat-insulating shell is fixedly connected to the bottom of the sealing rubber ring. Multiple water-absorbing plates are fixedly connected to the inner side of the heat-insulating shell.

[0014] As a further description of the above technical solution:

[0015] The top of the heat-insulating outer shell is fixedly connected to the bottom of the sealing rubber ring, the outside of the sealing inner shell is slidably connected to the inside of the sealing top shell, the bottom of the sealing inner shell is fixedly connected to a sealing filter screen, the bottom of the sealing inner shell is fixedly connected to a threaded connecting ring, and the outside of the threaded connecting ring is threadedly connected to a rotating bottom shell.

[0016] As a further description of the above technical solution:

[0017] The outer surface of the heat-insulating shell is slidably connected to a fixed support ring, and the outer surface of the fixed support ring is fixedly connected to a support hole plate.

[0018] As a further description of the above technical solution:

[0019] A heat-conducting plate three is fixedly connected inside the heat dissipation fins, a support plate is fixedly connected to the outside of the heat-conducting plate three, a heat-conducting plate two is fixedly connected to the top of the heat dissipation fins, and a cooling fan is fixedly connected to the top of the heat dissipation fins.

[0020] As a further description of the above technical solution:

[0021] The connecting heat-conducting plate is slidably connected to the inner side of the supporting protective shell, the bottom of the inner side of the supporting protective shell is fixedly connected to the bottom of the electromagnetic heater, and the outer side of the supporting fixing plate is fixedly connected to the inner side of the supporting protective shell.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this invention, when the reagent is placed inside the sealed inner shell, the sealed top shell slides downwards. At this time, the sealing rubber ring plays a crucial role, forming a tight seal to effectively prevent external moisture intrusion and ensure that the reagent does not become damp or deteriorate. The sealed inner shell and the insulating outer shell together create a storage space for the desiccant. The connecting absorbent plate can quickly absorb external moisture from the reagent, allowing the desiccant to fully exert its drying effect, ensuring a dry and stable internal environment, and improving the shelf life of the reagent and the reliability of experiments. In addition, the threaded connecting ring and the rotating bottom shell form a convenient disassembly structure, facilitating timely replacement of the internal desiccant and maintaining efficient drying performance. The simple operation greatly improves the convenience of using the instrument.

[0024] 2. In this invention, when the electromagnetic heater is activated, it quickly heats the first connecting heat-conducting plate. The cooling fan and the connecting heat-conducting plate not only provide stable support for the overall structure, ensuring stable operation of the instrument, but also, in conjunction with the cooling fan, efficiently transfer the heat generated by the first connecting heat-conducting plate to the interior of the second connecting heat-conducting plate. This process allows for the rational transfer of heat within the system, thereby achieving the purpose of maintaining the temperature of the dry outer shell. The stable temperature insulation effect prevents the internal desiccant from becoming damp and ineffective, ensuring that the reagents are in a suitable dry environment, improving the quality of reagent preservation, and ensuring the accuracy and reliability of the results of isothermal fluorescence amplification experiments.

The drying shell 2 includes a sealing connecting ring 206, which serves a dual function of connection and sealing. It securely connects the drying component 2012 to other parts while preventing external air and moisture from entering the drying component 2012. 2. Inside, a drying assembly 2012 is fixedly connected to the bottom of a sealed top shell 201 and a sealing connecting ring 206. The drying assembly 2012 includes a sealed inner shell 205, which provides storage space for the medicine and, in conjunction with other components, creates a relatively independent drying environment for the desiccant, preventing direct contact between the desiccant and the medicine. The bottom of the sealing connecting ring 206 is also fixedly connected to the sealed inner shell 205, providing storage space for the medicine and, in conjunction with other components, creating a relatively independent drying environment for the desiccant, preventing direct contact between the desiccant and the medicine. An insulating outer shell 203 is fixedly connected to the outside of the sealing connecting ring 206, providing storage space for the desiccant and also serving an insulating function to reduce heat loss and maintain internal temperature. To ensure the stability of the drying environment, multiple water-absorbing plates 204 are fixedly connected inside the sealed inner shell 205 to absorb moisture from the outside of the agent, playing a preliminary drying role and assisting the desiccant in achieving a better drying effect. The top of the water-absorbing plates 204 is fixedly connected to the bottom of the sealing ring 206. A sealing rubber ring 202 is slidably connected to the bottom of the sealed top shell 201 to enhance the sealing performance and ensure the stability of the drying environment. The bottom of the sealing rubber ring 202 is fixedly connected to the heat-insulating outer shell 203, which provides storage space for the desiccant and also plays a role in heat preservation, reducing heat loss and maintaining the stability of the internal drying environment. Multiple water-absorbing plates 204 are fixedly connected to the inner side of the heat-insulating outer shell 203, and the top of the heat-insulating outer shell 203 is fixedly connected to the bottom of the sealing ring 206. The sealing inner shell 205 is fixedly connected to the bottom of the sealing rubber ring 202. The outer side of the sealing inner shell 205 is slidably connected to the inner side of the sealing top shell 201. The bottom of the sealing inner shell 205 is fixedly connected to a sealing filter screen 207 to prevent desiccant particles from entering the drug storage area, while allowing water vapor to pass through to ensure the drying effect. The bottom of the sealing inner shell 205 is fixedly connected to a threaded connecting ring 208. The outer side of the threaded connecting ring 208 is threadedly connected to a rotating bottom shell 209 for easy disassembly and replacement of the internal desiccant. The outer side of the heat insulation shell 203 is slidably connected to a fixed support ring 2010. The outer side of the fixed support ring 2010 is fixedly connected to a support perforated plate 2011 to provide additional support and fixation for the drying shell 2, ensuring the stability of its structure.

[0033] Reference Figures 1 to 3 The insulation mechanism 3 includes an electromagnetic heater 301, which serves as a heat source to generate heat and provide the energy required for insulation of the reagent tray. A connecting heat-conducting plate 302 is fixedly connected to the top of the electromagnetic heater 301. A heat dissipation fin 303 is fixedly connected to the top of the connecting heat-conducting plate 302, rapidly transferring the heat generated by the electromagnetic heater 301 to the heat dissipation fin 303. A connecting heat-conducting plate 307 is fixedly connected inside the heat dissipation fin 303, assisting in heat transfer and providing structural support. A supporting plate 305 is fixedly connected to the outside of the connecting heat-conducting plate 307, securing the heat-conducting plate 307 to other components and ensuring the overall integrity of the insulation. The insulation mechanism 3 has a stable structure. The top of the heat dissipation fins 303 is fixedly connected to a heat-conducting plate 306, which further conducts the heat transferred from the heat dissipation fins 303 to the supporting protective shell 1 and the dry outer shell 2 to achieve the insulation effect. The top of the heat dissipation fins 303 is fixedly connected to a cooling fan 304, which accelerates airflow, enhances heat transfer efficiency, and ensures that heat can be quickly and evenly transferred to the parts that need to be insulated.

The bottom of the inside of the supporting protective shell 1 is fixedly connected to the bottom of the four electromagnetic heaters 301. The outside of the supporting fixing plate 305 is fixedly connected to the inside of the supporting protective shell 1.

[0034] Working principle: When the agent is placed inside the sealed inner shell 205, the sealing top shell 201 slides downwards, and the sealing rubber ring 202 provides a sealing effect. The sealed inner shell 205 and the heat-insulating outer shell 203 provide storage space for the desiccant inside. The water-absorbing plate 204 is used to absorb the external moisture of the agent, which is then dried by the agent. At the same time, the threaded connecting ring 208 and the rotating bottom shell 209 provide a disassembly effect, thereby achieving the effect of replacing the internal desiccant.

[0035] When the electromagnetic heater 301 starts running, it drives the heat-conducting plate 302 to heat up. At the same time, the cooling fan 304 and the heat-conducting plate 307 provide support for it. The heat dissipation fins 303 and the cooling fan 304 conduct the heat inside the heat-conducting plate 302 into the heat-conducting plate 306, thereby achieving the effect of protecting the dry shell 2 and keeping it warm.
