The second quality control position is located between the first quality control position and the third quality control position, and the first quality control position is located on the side of the second quality control position closer to the second accommodating area. The concentration of the quality control material contained in the corresponding centrifuge tubes stored in the first quality control position, the second quality control position, and the third quality control position increases sequentially.

The holder body has multiple accommodating areas, each of which is provided with a tube accommodating position. The multiple accommodating areas include at least a first accommodating area, a second accommodating area, a third accommodating area, and a fourth accommodating area.

It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not the entire structure.

[0033] like Figures 1 to 5As shown, this embodiment provides a centrifuge tube holder for packaging diagnostic reagents. The centrifuge tube holder includes a holder body 1 and a partition 2. The holder body 1 is provided with multiple accommodating areas 10, each accommodating area 10 being provided with a tube accommodating position 11. The multiple accommodating areas 10 include at least a first accommodating area 10a, a second accommodating area 10b, a third accommodating area 10c, and a fourth accommodating area 10d. The partition 2 is connected to the holder body 1, and two adjacent tube accommodating positions 11 are separated by the partition 2. The tube accommodating position 11 located in the first accommodating area 10a is used to store centrifuge tubes containing blank samples, the tube accommodating position 11 located in the second accommodating area 10b is used to store centrifuge tubes containing calibrators, the tube accommodating position 11 located in the third accommodating area 10c is used to store centrifuge tubes containing quality control samples, and the tube accommodating position 11 located in the fourth accommodating area 10d is used to store centrifuge tubes containing internal standards.

[0034] Diagnostic reagent packaging refers to the process of individually packaging various reagents required for a test according to the dosage ratio, and then forming a reagent kit; centrifuge tube holders are mainly used in diagnostic reagent packaging to hold centrifuge tubes, restrict the position of centrifuge tubes, and prevent centrifuge tubes from shaking or colliding.

[0035] Multiple centrifuge tubes are used to hold different reagents, among which blank samples, calibrators, quality control samples, and internal standards are the four most frequently used diagnostic reagents. Blank samples are used to test blank samples to eliminate the influence of external factors on the test results. They can be used to check the reagent composition, reagent content, and whether the reagents have been contaminated throughout the sample processing. Calibrators are prepared using standard substances to ensure the accuracy and reliability of the test results. Quality control samples are used as standard samples for calibration; their concentration is known. Internal standards are reagents used for quantitative analysis; their content is known to ensure the accuracy of quantitative analysis and improve the precision of the test.

[0036] By setting multiple accommodating areas 10 on the support body 1, and setting accommodating tube positions 11 in each accommodating area 10, and using partitions 2 to separate adjacent accommodating tube positions 11, centrifuge tubes containing different reagents (such as blank samples, calibrators, quality control samples and internal standards) can be stored in the corresponding accommodating tube positions 11 of the accommodating area 10, avoiding the messy placement of centrifuge tubes containing different reagents, and taking out the corresponding centrifuge tubes according to the accommodating area 10, saving time and improving efficiency, and greatly reducing the possibility of errors in handling.

[0037] Optionally, the second container 10b and the third container 10c are located between the first container 10a and the fourth container 10d. By placing the second container 10b and the third container 10c between the first container 10a and the fourth container 10d, that is, placing centrifuge tubes containing calibrators and quality control samples between centrifuge tubes containing blank samples and centrifuge tubes containing internal standards, the internal standards can be isolated from the blank samples using calibrators and quality control samples, avoiding contamination of the blank samples due to factors such as the volatilization of internal standards, and effectively reducing the risk of contamination transmission.

[0038] In this embodiment, the first accommodating area 10a, the second accommodating area 10b, the third accommodating area 10c, and the fourth accommodating area 10d are arranged side by side in sequence. This arrangement helps staff quickly locate the corresponding accommodating area 10 during storage, conforms to standard laboratory operating procedures, reduces errors in position switching during operation, avoids misplacement or omission, and further improves testing efficiency.

[0039] Optionally, the third containment area 10c is provided with three containment tube positions 11. The three containment tube positions 11 in the third containment area 10c are the first quality control position 111, the second quality control position 112, and the third quality control position 113. The second quality control position 112 is located between the first quality control position 111 and the third quality control position 113. The first quality control position 111 is located on the side of the second quality control position 112 that is closer to the second containment area 10b. The concentration of the quality control sample stored in the corresponding centrifuge tubes of the first quality control position 111, the second quality control position 112, and the third quality control position 113 increases sequentially.

[0040] Centrifuge tubes containing quality control samples are placed by setting up a first quality control position 111, a second quality control position 112, and a third quality control position 113, thereby accommodating quality control samples with multiple concentration gradients. The first quality control position 111 is located on the side of the second quality control position 112 near the second containment area 10b, and the concentration of the quality control samples in the centrifuge tube increases sequentially, which is suitable for the standard operating sequence. This facilitates the processing of low-concentration quality control samples first and then high-concentration quality control samples, thereby reducing the interference of high-concentration reagent residues on the detection results of low-concentration reagents. Furthermore, if the detection results do not present the expected concentration gradient, it can be quickly identified, and it can be promptly determined whether there is a problem with instrument calibration or reagents.

[0041] Optionally, the first containment area 10a and the fourth containment area 10d each have one containment tube position 11, and the second containment area 10b has seven containment tube positions 11, all arranged side by side. Based on the three containment tube positions 11 in the third containment area 10c, and considering that only one centrifuge tube containing a blank sample and one centrifuge tube containing an internal standard are needed in the same batch of experiments, the first containment area 10a and the fourth containment area 10d each have one containment tube position 11. To achieve symmetrical balancing, the second containment area 10b has seven containment tube positions 11 to accommodate calibrators with multiple concentration gradients, and all containment tube positions 11 are arranged side by side, thus ensuring that the centrifuge tubes containing blank samples, calibrators, quality control samples, and internal standards can maintain balance when centrifuged together.

[0042] Furthermore, a positioning block 12 protrudes from the top of the support body 1, and a positioning groove 121 is provided on one side of the positioning block 12 for limiting the cap of the centrifuge tube. By setting the positioning block 12 on the top of the support body 1 and opening the positioning groove 121 on the positioning block 12, the cap of the centrifuge tube can be limited when storing capped centrifuge tubes, so as to avoid the cap from obstructing the storage of adjacent centrifuge tubes after it is opened, which helps to save space and improve the utilization rate of the centrifuge tube support.

[0043] In this embodiment, a positioning block 12 is provided between two adjacent accommodating tube positions 11, and 11 positioning blocks 12 are provided at intervals. All positioning blocks 12 have the same structure. One accommodating tube position 11 in the fourth accommodating area 10d is an inner standard position. A positioning block 12 is provided between the third quality control position 113 and the inner standard position, and the positioning groove 121 of the positioning block 12 is located on the side close to the third quality control position 113 to limit the centrifuge tube cap stored in the third quality control position 113.

[0044] Understandably, due to the strict requirements on storage containers for internal standard reagents, there are tiny gaps at the connection between the tube body and the cap of a capped centrifuge tube. If a capped centrifuge tube is used to store the internal standard reagent, the reagent will leak out and be lost through these tiny gaps. Therefore, capped centrifuge tubes are generally not chosen for storing internal standard reagents. That is, the centrifuge tubes stored in the tube position 11 of the fourth storage area 10d are not capped centrifuge tubes, so there is no need to set up a positioning block 12 to limit the cap.

[0045] In this embodiment, the support body 1 and the partition 2 are an integral structure. The support body 1 has a receiving space (including multiple receiving areas 10). The top of the partition 2 is connected to the inner top wall of the support body 1, and the bottom of the partition 2 is flush with the bottom of the support body 1. The partition 2 divides the receiving space in the support body 1 into multiple receiving tube positions 11. The top of the support body 1 has an opening corresponding to each receiving tube position 11 for centrifuge tubes to be inserted and stored in the receiving tube position 11. It can be understood that when the centrifuge tube is inserted into the receiving tube position 11, the partition 2 can restrict the position of the centrifuge tube and prevent the centrifuge tube from tilting, tilting, or shifting.

[0046] Optionally, the height of at least part of the partition 2 is one-third of the height of the centrifuge tube. By setting the height of at least part of the partition 2 to one-third of the height of the centrifuge tube, the stability of the centrifuge tubes when stored in the receiving position 11 of the centrifuge tube holder is ensured, while also allowing most of the top of the centrifuge tube to be exposed outside the centrifuge tube holder for observation of the reagents inside. Simultaneously, the centrifuge tube body has a groove with a label affixed to it, exposed outside the centrifuge tube holder. The label indicates reagent information (e.g., name, serial number, concentration, content, etc.), enabling staff to quickly identify reagents when handling them.

[0047] In this embodiment, the tube positions 11 in the first accommodating area 10a, the second accommodating area 10b, and the third accommodating area 10c are all used to store centrifuge tubes of the same size with caps, while the centrifuge tubes stored in the tube position 11 of the fourth accommodating area 10d are non-capped centrifuge tubes (for example, screw-cap centrifuge tubes can be used); the partition 2 includes a first partition 21 and a second partition 22, with 10 first partitions 21 spaced apart and one second partition 22. The first partitions 21 are flat, and the second partitions 22 are cylindrical with closed bottoms. The third quality control position 113 and the tube position 11 of the fourth accommodating area 10d are separated by the second partition 22; the height of the first partition 21 is one-third of the height of the capped centrifuge tubes, and the height of the second partition 22 is one-third of the height of the centrifuge tubes stored in the tube position 11 of the fourth accommodating area 10d.

[0048] In other embodiments, the shape and height of the partition 2 can be adapted to the shape and height of the centrifuge tubes stored in different accommodating tube positions 11.

[0049] Optionally, the bottom of the support body 1 is provided with an anti-slip pad. During centrifugation, the centrifuge tube support needs to be fixed on the centrifuge tray. By providing an anti-slip pad at the bottom of the support body 1, the friction between the bottom of the centrifuge tube support and the centrifuge can be increased, preventing the support body 1 from sliding and shifting during centrifugation. It can also play a certain buffering role, preventing the centrifuge tubes from breaking due to severe vibration. In this embodiment, the anti-slip pad is made of rubber; the anti-slip pad is glued and fixed to the bottom of the support body 1. In other embodiments, a slot can also be provided at the bottom of the support body 1, and the anti-slip pad can be pressed and embedded into the slot.

[0050] Optionally, a locking protrusion 13 is provided on the outer surface of the support body 1, which is used to engage with the tray of the centrifuge. By setting the locking protrusion 13 to engage with the tray of the centrifuge, the structure is simple, the insertion is quick and convenient, saving time and effort, and preventing the centrifuge tube support from loosening or slipping during centrifugation.

[0051] In this embodiment, three locking protrusions 13 are spaced apart on the outer surface of the support body 1. By providing multiple locking protrusions 13, the centrifuge tube support can engage with the centrifuge tray from different positions. The multiple engagement points can disperse the centrifugal force, reduce stress concentration between the centrifuge tube support and the tray during high-speed rotation, and prevent deformation or breakage of the centrifuge tube support due to excessive local stress.

[0052] The centrifuge tube holder for diagnostic reagent packaging provided in this embodiment can be fixed on the tray of a centrifuge; wherein, the holder body 1 is fixed to the tray by a snap-fit ​​protrusion 13. By setting up the centrifuge tube holder and optimizing the structural layout, it is possible to achieve partitioned storage of centrifuge tubes containing different reagents, and to engage with the centrifuge tray, thereby meeting the requirements of high efficiency and safety in reagent handling and improving the efficiency of centrifuge tube retrieval.

[0053] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
