[0042] like Figures 1 to 5 As shown, this embodiment provides a sample rack, which includes a base 100 and a plurality of support frames 200. The base 100 has a plurality of mounting slots 110 spaced apart along a first direction; the plurality of support frames 200 correspond one-to-one with the plurality of mounting slots 110, and the support frames 200 can be placed in or removed from the mounting slots 110; the support frames 200 are provided with a plurality of receiving slots 211 spaced apart along a second direction, and a plurality of sample tubes are placed in the receiving slots 211. The first direction is the X-direction, and the second direction is the Y-direction, and the two are perpendicular to each other.

[0043] When inspecting samples, a support frame 200 can be removed to observe several sample tubes within it, thus improving inspection efficiency. In addition, compared to the sample tubes, the support frame 200 is easier to place and remove, reducing the risk of the tubes falling and improving the safety of sample condition inspection.

[0044] In some embodiments, the opening of the mounting slot 110 faces upward, allowing the support frame 200 to be placed downward in the mounting slot 110 or removed upward from the mounting slot 110. Removing the support frame 200 upward aligns with existing inspection procedures, facilitating quick product adaptation for staff and reducing operational difficulty.

[0045] Regarding the number of sample tubes that the sample rack can hold, in some embodiments, the base 100 has at least four mounting slots 110, and the support frame 200 has at least ten receiving slots 211. In this embodiment, the sample rack can hold at least 40 sample tubes. In other embodiments, the number of mounting slots 110 in the base 100 and the number of receiving slots 211 in the support frame 200 can be appropriately adjusted according to the testing equipment and operating space.

[0046] Because sample types are diverse, including but not limited to blood collection tubes, cell cryopreservation tubes, and nucleic acid preservation tubes, and the sizes of the sample tubes vary, in this embodiment, the support frame 200 includes a support body 210 and an elastic member 220. A receiving groove 211 is disposed on the support body 210, and one end of the elastic member 220 is located at the opening of the receiving groove 211, while the other end extends downward and inward to abut against sample tubes of different diameters. The elastic member 220 abuts against the sample tubes, preventing them from tipping over. The elastic member 220 is sheet-like and there are at least two of them. Each elastic member 220 is arranged at intervals around the center line of the receiving groove 211. For example, there are three elastic members 220, evenly distributed at intervals around the center line of the receiving groove 211. In this embodiment, the end of the elastic member 220 near the center of the receiving groove 211 is bent into an arc shape and protrudes towards the center of the receiving groove 211 to avoid obstruction during the handling of the sample tubes. In other words, one end of the elastic element 220 is a connecting end, which is bonded, inserted, or injection molded integrally with the support body 210. The arc-shaped abutment end applies a horizontal force to the sample tube. The elastic element 220 is made of plastic or stainless steel, and the support body 210 is made of plastic.

[0047] In some embodiments, the base 100 is provided with a viewing window 120, which faces the mounting groove 110. The above structure allows the operator to observe the support body 210 through the viewing window 120 to determine whether the support body 210 has been placed in place.

[0048] The support body 210 is made of transparent material. The above structure allows staff to observe the sample tubes through the viewing window 120 and the support body 210 to determine whether the sample tubes are placed in place. In some embodiments, the entire base 100 is made of transparent material.

[0049] To accommodate sample tubes of different heights, the support frame 200 also includes a shim 230. The support body 210 includes a receiving portion 212 and support portions 213 located at both ends of the receiving portion 212 along the Y direction. The support portions 213 extend vertically. A receiving groove 211 is located in the receiving portion 212 and extends vertically through it. The shim 230 is located in the supported portion 213 and below the receiving groove 211. The shim 230 supports the bottom of the sample tube and its height relative to the receiving portion 212 is adjustable. The vertical direction is the Z direction. The Z direction is perpendicular to both the X and Y directions.

[0050] In some embodiments, the shim 230 is sheet-shaped, and each support portion 213 has a plurality of corresponding mounting holes 214. Both ends of the shim 230 pass through two corresponding mounting holes 214. Specifically, the left support portion 213 has a plurality of first holes spaced apart vertically, and the right support portion 213 has a plurality of second holes spaced apart vertically. The first holes and second holes are arranged in a one-to-one correspondence. One end of the shim 230 passes through a first hole, and the other end passes through a second hole. Further, in the same support portion 213, two adjacent mounting holes 214 are connected by a notch 215. The width of the notch 215 is less than the width of the shim 230 in the X direction, but greater than the thickness of the shim 230 in the vertical direction. Using the structure of the notch 215, the shim 230 can be flipped, allowing it to move upwards into the upper mounting hole 214 after being flipped 90° (see...). Figure 4 (The dotted line feature in the middle), or move it down into the mounting hole 214 below, and then rotate it 90° to place it in the mounting hole 214.

[0051] To improve the connection reliability between the sample holder and the base 100, in some embodiments, the sample holder further includes a fixing component, and the support frame 200 and the base 100 are fixed by the fixing component. Specifically, the fixing component includes a buckle 130 and a slot 216. One of the support frame 200 and the base 100 is equipped with a buckle 130, and the other is provided with a slot 216, and the buckle 130 can be engaged in the slot 216. Exemplarily, the buckle 130 is provided on the base 100, and the support frame 200 is provided with a slot 216. There are two buckles 130, which are arranged at intervals along the Y direction at both ends of the base 100, and each end of the support frame 200 is provided with a slot 216, which corresponds to the two buckles 130. In this embodiment, the base 100 is provided with a connecting hole that connects to the mounting groove 110, and the buckle 130 can pass through the connecting hole and be engaged in the slot 216. The snap fastener 130 includes a resilient arm and a connector located at the upper end of the resilient arm. The lower end of the resilient arm is connected to the base 100. The connector can move away from or near the base 100 to be removed from or inserted into the slot 216.

[0052] The samples have specific temperature requirements. To ensure sample stability in different room temperature environments, the base 100 is equipped with a sliding channel. The sample rack also includes a drawer 300, which can be placed in or removed from the sliding channel. The drawer 300 is used to hold ice or dry ice to stabilize the temperature of the samples in the test tubes within a preset range, ensuring sample stability and the reliability of test results. The required temperature range for the samples is -20℃ to -5℃. Furthermore, the sample rack also includes a temperature detection element 310, which detects the temperature of the test tubes, thus reflecting the sample temperature. The temperature detection element 310 is located in the drawer 300. The sample rack also includes a notification element, which is communicatively connected to the controller. The temperature detection element 310 is also communicatively connected to the controller. When the temperature exceeds a preset value, it indicates that the ice or dry ice is used up. The temperature detection element 310 sends a temperature signal to the controller. Upon receiving the temperature signal, the controller sends a notification signal to the notification element. Upon receiving the notification signal, the notification element sends a notification message to remind the staff to add ice or dry ice.
