[0026] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0027] See also Figure 1 and Figure 2 , the sample preservation device for infectious disease detection provided by the utility model is now described. The sample preservation device for infectious disease detection includes: a box body 3, a support plate 2, a cooling box 7, a liquid storage box 11 and an adjusting member 4. The support plate 2 is placed in the box body 3, and a plurality of positioning holes for positioning the detection tube 1 are provided on the support plate 2. The cooling box 7 is provided below the support plate 2, and a refrigerant is stored in the cooling box 7. The liquid storage box 11 is provided in the box body 3 and positioned above the cooling box 7; the liquid storage box 11 is filled with a liquid for mixing with the refrigerant and cooling the refrigerant; a channel is provided between the liquid storage box 11 and the cooling box 7. The adjusting member 4 is slidably arranged on the box body 3, and the end of the adjusting member 4 squeezes the channel to seal or open the channel.

[0028] The sample storage device for infectious disease testing provided by the present invention has the following advantages: Compared with the prior art, the support plate 2 of the present invention is placed within a housing 3 and is provided with multiple positioning holes. A cooling box 7 is positioned below the support plate 2, while a liquid storage box 11 is positioned within the housing 3 and above the cooling box 7. A passage is provided between the liquid storage box 11 and the cooling box 7, and an adjustment member 4 slides on the housing 3.

[0029] In actual use, refrigerant is placed in cooling box 7, and liquid, which mixes with the refrigerant and lowers its temperature, is filled into liquid storage box 11. After positioning detection tube 1 in the positioning hole, adjusting member 4 is removed, connecting the passage between liquid storage box 11 and cooling box 7. The liquid mixes with the refrigerant, thereby lowering the temperature of cooling box 7. Once the temperature of cooling box 7 is lowered, detection tube 1 can be cooled. This application has a relatively simple structure, is easy to operate, and more importantly, is low-cost, ensuring that detection tube 1 is kept at a low temperature.

[0030] In some embodiments of the sample storage device for infectious disease detection provided in this application, please refer to Figure 1 and Figure 2 A blocking piece 12 is provided in the positioning hole. The blocking piece 12 is used to block the positioning hole and separate from the positioning hole when the detection tube 1 is inserted into the positioning hole. First, during the detection process, the sample needs to be placed in the detection tube 1. At this time, it is necessary to cool it in time, so the channel needs to be in a connected state. However, if no treatment is performed at this time, the positioning holes on the support plate 2 make the space at the bottom of the support plate 2 communicate with the outside world. Due to the poor sealing performance, the temperature in the space between the support plate 2 and the box body 3 cannot be effectively reduced.

[0031] To address this issue, a sealing piece 12 is provided in each positioning hole. The sealing piece 12 provides a certain degree of isolation, ensuring that the positioning hole is sealed when the detection tube 1 is not inserted. The sealing piece 12 is detachably connected to the positioning hole. In this embodiment, the sealing piece 12 is bonded to the positioning hole. When the detection tube 1 is inserted, the sealing piece 12 separates from the positioning hole, ensuring airtightness when not inserted and ensuring separation from the positioning hole after the detection tube 1 is inserted.

[0032] In some embodiments of the sample storage device for infectious disease detection provided in this application, please refer to Figure 1 and Figure 2 , a plurality of fins 8 are provided on the outside of the cooling box 7. In order to ensure that the heat can be effectively absorbed by the refrigerant, it is necessary to increase the contact area between the cooling box 7 and the outside world. For this purpose, a plurality of fins 8 are provided on the outer side of the cooling box 7. The plurality of fins 8 are made of metal materials and can effectively realize heat transfer.

[0033] The cooling box 7 is inserted into the box body 3. A feeding port is provided on the cooling box 7. The feeding port is filled with a sealing plug. After use, the heated refrigerant is taken out through the feeding port and new refrigerant that has not come into contact with liquid is added after cleaning.

[0034] In some embodiments of the sample storage device for infectious disease detection provided in this application, please refer to Figure 1 and Figure 2A fan 10 is installed in the box 3 and is located on one side of the cooling box 7. The fan 10 can achieve rapid flow of air in the box 3, so that the temperature of the air in the space between the box 3 and the support plate 2 can be quickly cooled. Because the temperature of the newly inserted detection tube 1 is relatively high, the fan 10 can quickly reduce the temperature of the newly inserted detection tube 1, ensuring the accuracy of the final test result and preventing the deterioration of the sample in the detection tube 1.

[0035] In some embodiments of the sample storage device for infectious disease testing provided herein, a desiccant is provided within the housing 3. If left untreated, moisture will remain in the air between the housing 3 and the support plate 2. More importantly, when the liquid comes into contact with the refrigerant, condensation will form on the inner walls of the housing 3. This accumulation of moisture can easily lead to the growth of bacteria and other organisms. To prevent this, a desiccant is provided within the housing 3 to absorb moisture from the air.

[0036] In an embodiment, a plurality of support blocks are fixed on the inner wall of the box body 3, and the top surfaces of the plurality of support blocks are in the same plane. The support plate 2 is placed on the plurality of support blocks. At the same time, a sealing ring is provided on the outer edge of the support plate 2. The sealing ring is used to seal the gap between the support plate 2 and the box body 3. More importantly, the sealing ring ensures the stability of the position of the support plate 2 relative to the box body 3. After the position of the support plate 2 is determined, the position of the positioned detection tube 1 is also determined, thereby avoiding the shaking of the detection tube 1.

[0037] In some embodiments of the sample storage device for infectious disease detection provided in this application, please refer to Figure 1 and Figure 2 , a connecting pipe 6 is connected between the cooling box 7 and the liquid storage box 11, and a channel is formed in the connecting pipe 6; the adjusting part 4 is a blocking plate, which squeezes the connecting pipe 6 to block the channel. It is necessary to ensure that the liquid can flow between the cooling box 7 and the liquid storage box 11, and at the same time, it is necessary to prevent the liquid inside the liquid storage box 11 from flowing into the box body 3. More importantly, it is necessary to ensure that the adjusting part 4 can effectively block or open the channel. Based on the above reasons, the two ends of the connecting pipe 6 are respectively connected to the cooling box 7 and the liquid storage box 11. The connecting pipe 6 is made of flexible material, and the blocking plate is slidably arranged on one side of the connecting pipe 6. When it is necessary to block the channel, slide the blocking plate and squeeze the blocking plate to squeeze the connecting pipe 6 until the connecting pipe 6 is completely closed. In actual application, positioning nails or other methods can be installed to prevent the blocking plate from moving. When it is necessary to open the channel, slide the blocking plate again. The whole operation is relatively simple and can be used multiple times.

[0038] In some embodiments of the sample storage device for infectious disease detection provided in this application, please refer to Figure 1 and Figure 2A limit block 9 is provided in the box body 3, and the limit block 9 is located on the side of the connecting pipe 6 away from the blocking plate. The limit block 9 is used to limit the position of the connecting pipe 6. The limit block 9 can limit the position of the connecting pipe 6, so that the blocking plate can squeeze and block the connecting pipe 6 smoothly.

[0039] In some embodiments of the sample storage device for infectious disease testing provided herein, a battery electrically connected to a fan 10 is provided within the housing 3. To quickly reduce the temperature within the housing 3, the flow of gas within the housing 3 needs to be accelerated. For this reason, the fan 10 is installed on one side of the housing 3, i.e., on the side of the fins 8. Since the entire housing 3 needs to be portable, a battery is installed in a corresponding position within the housing 3. The battery is removable and connected to the fan 10 via wires, providing power for the fan 10's rotation.

[0040] In some embodiments of the sample storage device for infectious disease detection provided in this application, a clearance groove is provided in the box body 3, and the blocking plate is slidably disposed in the clearance groove. For a more detailed description, first, a clearance groove is provided in the box body 3, the notch of the clearance groove is arranged outward, and the blocking plate is slidably disposed in the clearance groove. The clearance groove can limit the sliding direction of the blocking plate, and ultimately the purpose is to enable the blocking plate to effectively squeeze the connecting tube 6 and achieve blocking of the connecting tube 6.

[0041] In some embodiments of the sample storage device for infectious disease testing provided herein, two conductive plates are positioned within the upper and lower walls of the clearance slot. The upper two conductive plates are electrically connected to the positive and negative terminals of the battery, respectively; the lower two conductive plates are electrically connected to the positive and negative terminals of the fan 10, respectively. Two conductive posts 5 are fixed to the blocking plate. The two conductive posts 5, through the sliding movement of the blocking plate, contact the upper and lower conductive plates, creating a pathway between the battery and the fan 10. Traditionally, the blocking plate is withdrawn, allowing the liquid to come into contact with the refrigerant. As the refrigerant temperature decreases, the temperature of the cooling box 7 also decreases. Medical personnel then connect the battery to the fan 10, enabling the fan 10 to rotate. The entire operation can be divided into two steps. To simplify the process, conductive posts 5 are provided on the blocking plate, extending through the blocking plate. When the blocking plate slides outward, connecting the connecting tube 6, the conductive posts 5 connect to the upper and lower conductive plates, respectively, forming a closed pathway between the battery, the fan 10, and the conductive posts 5, ultimately achieving fast and efficient operation.

[0042] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
