Description

Technical Field

[0001] The utility model relates to the technical field of sample preservation, and in particular to a device and system for continuously measuring sample temperature. Background Art

[0002] At present, the medical research field has increasingly higher requirements for the quality of biological sample preservation, and the storage temperature of biological samples is an important indicator for evaluating the quality of sample preservation.

[0003] Typically, biobanks monitor sample storage temperatures using temperature sensors installed on storage devices. These sensors continuously measure the temperature of the storage space over a specific period of time, providing evidence of the sample's temperature. This method, to a certain extent, reflects the temperature changes in the storage space during the storage process.

[0004] However, the aforementioned methods for measuring or monitoring biological sample storage temperatures are subject to certain errors. The measured spatial temperature of the storage device is significantly affected by the device's usage (e.g., opening and closing the device). For example, when the door of a -80°C upright refrigerator is opened, the internal temperature fluctuates rapidly due to the principle that cold air descends and hot air rises, easily triggering an alarm in the refrigerator's temperature monitoring system. For samples stored in a refrigerator, due to differences in material density, the temperature of the sample itself changes slowly relative to the spatial temperature of the storage device. Therefore, the values ​​recorded by the temperature monitoring system of a refrigerator or other storage device are insufficient to fully reflect the temperature changes of the sample itself.

[0033] The following is a detailed description of the specific embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention and are not intended to limit the present invention.

[0034] The first embodiment of the present invention provides a device for continuously measuring the temperature of a sample. Figure 1 As shown, it includes a sample tube 1, an internal temperature detection component 2, an external temperature detection component 3 and a limit component 4;

[0035] A limiting assembly 4 is provided in the sample tube 1. The internal temperature detection assembly 2 extends into the sample tube 1 and is connected to the limiting assembly 4. The limiting assembly 4 is configured to limit the internal detection end 21 of the internal temperature detection assembly 2 to a position suspended above the lower portion of the sample tube 1.

[0036] The external detection end 31 of the external temperature detection component 3 is attached to the outer wall of the sample tube 1 and is used to detect the ambient temperature of the sample tube 1 .

[0037] When using the above-described continuous sample temperature measurement device, a sample can be placed in a sample tube 1. The inner detection end 21 of the inner temperature detection assembly 2 is immersed in the sample to directly detect the sample's temperature. The outer detection end 31 of the outer temperature detection assembly 3 collects the temperature of the environment surrounding the sample tube. During this process, the limiting assembly 4 allows the inner detection end 21 to be suspended below the interior of the sample tube 1, ensuring that the inner detection end 21 stably detects the sample temperature.

[0038] The sample temperature continuous measurement device provided in the above embodiment can not only detect the temperature of the environment in which the sample tube 1 is located, but also directly detect the sample temperature, which can truly reflect the actual temperature of the sample and more comprehensively monitor the sample preservation quality.

[0039] It should be noted that the “inside” and “outside” of the inner detection end 21 and the outer detection end 31 are relative to the sample tube 1 . The inner detection end 21 is located inside the sample tube 1 , and the outer detection end 31 is located outside the sample tube 1 .

[0040] The structure of the sample tube 1 is described in detail below:

[0041] In an optional embodiment, if Figure 1 As shown, the sample tube 1 includes a tube body 11 and a tube cap 12 connected to the tube body 11 .

[0042] During use, the connection between the tube cap 12 and the tube body 11 can be cancelled, the sample is added into the tube body 11 , and then the tube cap 12 is covered on the tube body 11 .

[0043] Specifically, in order to facilitate assembly and disassembly of the pipe cap 12 and the pipe body 11 , the pipe cap 12 and the pipe body 11 may be sealed by a threaded connection or a mortise and tenon connection.

[0044] In addition, the tube body 11 can be made of a low-temperature resistant (-80°C to -196°C) material, and can be selected with different capacities.

[0045] In an optional embodiment, if Figure 1 As shown, the sample tube 1 further includes a base 13 , and the tube body 11 is inserted into the base 13 .

[0046] The arrangement of the base 13 facilitates the vertical storage of the sample tube 1 and ensures that the inner detection end 21 can be stably placed in the sample.

[0047] In an optional embodiment, if Figure 1 As shown, in order to further ensure the stability of the base 13, the base 13 is provided with a counterweight 14. The counterweight 14 can increase the weight of the base 13 and effectively reduce the probability of the sample tube 1 tipping over during transportation.

[0048] Specifically, the counterweight 14 can be installed on the outer surface of the base 13 , for example, the counterweight 14 is installed on the bottom surface of the base 13 , or the counterweight 14 is arranged around the bottom end of the side surface of the base 13 .

[0049] The counterweight 14 can also be embedded in the base 13. For example, the bottom surface of the base 13 is recessed with a mounting groove, and the counterweight 14 is installed in the mounting groove, or the base 13 includes an upper seat and a lower seat, and a mounting cavity is formed between the upper seat and the lower seat, and the counterweight 14 is installed in the mounting cavity.

[0050] The structure of the limit assembly 4 is described in detail below:

[0051] In an optional embodiment, if Figure 1 As shown, when the sample tube 1 includes a tube body 11 and a tube cap 12 , one end of the limiting assembly 4 is connected to the tube cap 12 , and the other end extends along the axial direction of the tube body 11 toward the bottom of the tube body 11 .

[0052] When the pipe cap 12 is removed, the limiting assembly 4 can extend from the pipe body 11 following the pipe cap 12 . When the pipe cap 12 is installed, the limiting assembly 4 follows the pipe cap 12 and extends into the pipe body 11 .

[0053] It should be noted that any structure that can limit the inner detection end 21 of the inner temperature detection component 2 to be suspended above the lower portion of the sample tube 1 can be the limiting component 4 mentioned in the above embodiment.

[0054] In an optional embodiment, if Figure 1 As shown, the limiting assembly 4 includes a plurality of limiting claws 41 evenly spaced around the axis of the tube body 11, wherein:

[0055] One end of each limiting claw 41 is connected to the tube cap 12 , and the other end extends along the axial direction of the tube body 11 toward the bottom of the tube body 11 , and one end of each limiting claw 41 close to the bottom of the tube body 11 forms a clamping space for clamping the internal temperature detection component 2 .

[0056] When in use, the internal temperature detection component 2 is clamped in the clamping space by each limiting claw 41, so that the internal detection end 21 is suspended at the lower part of the internal space of the sample tube 1, avoiding contact between the internal detection end 21 and the inner wall of the sample tube 1, thereby ensuring the accuracy of the detection result of the internal detection end 21.

[0057] Specifically, the end of each limiting claw 41 can be inserted into the pipe cap 12, and the limiting claw 41 can be tightly matched with the pipe cap 12, or the limiting claw 41 can be clamped with the pipe cap 12 to thereby limit the position of the limiting claw 41 relative to the pipe body 11.

[0058] In an optional embodiment, each limiting claw 41 may be made of elastic material to prevent the limiting claw 41 from damaging the internal temperature detection component 2 when clamping the internal temperature detection component 2 .

[0059] In an optional embodiment, the surface of each limiting claw 41 forming the clamping space may also be provided with an elastic sheet for increasing the friction between the limiting claw 41 and the internal temperature detection assembly 2 .

[0060] In other embodiments, the limiting component 4 may also adopt other structures. For example, the limiting component 4 includes a clamp fixed on the inner wall of the tube body 11, and a torsion spring is provided in the clamp. Under the elastic action of the torsion spring, the clamp can grasp the internal temperature detection component 2.

[0061] The structure of the internal temperature detection component 2 is described in detail below:

[0062] In an optional embodiment, if Figure 1 As shown, the internal temperature detection assembly 2 includes a first circuit 22 and an internal detection end 21 . The first circuit 22 passes through the tube cap 12 and extends into the tube body 11 and is clamped in the clamping space. The internal detection end 21 is connected to the first circuit 22 .

[0063] The first circuit 22 can realize power and signal transmission, and the limiting component 4 limits the position of the internal detection end 21 by clamping the first circuit 22.

[0064] Specifically, a sealing ring may be provided between the first line 22 and the pipe cap 12 to ensure a sealed connection between the two.

[0065] The structure of the external temperature detection component 3 is described in detail below:

[0066] In an optional embodiment, if Figure 1 As shown, the external temperature detection component 3 includes a second circuit 32 and an external detection end 31 . The second circuit 32 can realize power and signal transmission, and the external detection end 31 can detect the temperature of the environment in which the sample tube 1 is located.

[0067] In an optional embodiment, if Figure 1 As shown, to facilitate the routing of the second line 32 , a routing groove 5 is provided between the base 13 and the tube body 11 . One end of the second line 32 is connected to the external detection end 31 , and the other end extends into the routing groove 5 and passes through the base 13 , extending from the side of the base 13 .

[0068] The arrangement of the wiring groove 5 can not only define the position of the second line 32 relative to the tube body 11 , but also ensure a more orderly extension of the lines in the sample temperature continuous measurement device.

[0069] The embodiment of the second aspect of the present invention is to provide a sample temperature continuous measurement system. The sample temperature continuous measurement system provided by the embodiment of the second aspect of the present invention includes a data acquisition and transmission module 6 and the above-mentioned sample temperature continuous measurement device;

[0070] The internal temperature detection component 2 and the external temperature detection component 3 in each sample temperature continuous measurement device are both connected to the data acquisition and transmission module 6 .

[0071] The sample temperature continuous measurement system provided by the embodiment of the second aspect of the present invention also includes a data acquisition and transmission module 6 connected to the internal temperature detection component 2 and the external temperature detection component 3. The data acquisition and transmission module 6 can centrally store the temperature data detected by the internal detection end 21 and the external detection end 31, making it convenient for users to monitor the sample storage temperature environment.

[0072] Specifically, in the above-mentioned sample temperature continuous measurement system, the internal temperature detection component 2 and the external temperature detection component 3 are used in combination to avoid false alarms of the sample temperature continuous measurement system due to the fluctuation of the ambient temperature of the sample tube 1 being significantly faster than the fluctuation of the sample's own temperature. Personnel can verify the actual temperature of the sample detected by the internal temperature detection component 2. If the actual temperature of the sample also fluctuates greatly, an alarm will be issued to monitor the sample preservation environment more accurately.

[0073] In an optional embodiment, if Figure 1 As shown, a magnetic structure 7 is provided on the outer surface of the data acquisition and transmission module 6, and the magnetic structure 7 is used to be adsorbed on an external supporting object.

[0074] The arrangement of the magnetic attraction structure 7 can allow the data acquisition and transmission module 6 to be adsorbed on an external supporting object, and the placement of the data acquisition and transmission module 6 is more flexible.

[0075] Specifically, the magnetic attraction structure 7 may include multiple magnetic sheets, and the magnetic sheets may be distributed on one surface of the data acquisition and transmission module 6 , or may be distributed on multiple surfaces of the data acquisition and transmission module 6 .

[0076] Specifically, the magnetic sheet can be installed on the bottom surface of the data acquisition and transmission module 6 , or on the side surface of the data acquisition and transmission module 6 , or on both the bottom surface and the side surface of the data acquisition and transmission module 6 .

[0077] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents.
