Description

Technical Field

[0001] This application relates to the field of in vitro diagnostics, and in particular to an adapter tube for a micro-volume blood sample container and an analysis system. Background Technology

[0002] In the field of in vitro diagnostics (IVD), when performing sample analysis in clinical testing, the sample needs to be placed in a sample tube, which is then placed in a sample holder (within the slot of the sample holder). The sample holder is placed in the sample loading area or temporary storage area, and the sample is then sent into the instrument to achieve batch testing and analysis.

[0003] With the continuous development and improvement of modern, miniaturized, and convenient laboratory medicine technology, the application of micro-volume blood / capillary blood is becoming increasingly widespread. However, micro-volume blood tubes differ significantly from conventional blood collection tubes in specifications, and there are various types of micro-volume blood tubes on the market (at least one of which differs in specifications, shape, or structure, such as bullet-shaped or Hitachi cups). Therefore, different adapters are needed to ensure that different types of micro-volume blood sample containers can be stably placed in the well positions of the sample holder with the assistance of the adapters, enabling automated / batch testing and analysis.

[0004] Adapters for micro-volume blood sample containers can, to some extent, solve the problem of automated micro-volume blood sample introduction via sample holders. However, in practical use, sample tube positions equipped with adapters can only accommodate the corresponding micro-volume blood sample containers, not other types of micro-volume blood sample containers, let alone whole blood sample tubes, causing inconvenience. Furthermore, for sample trays (array holders), the sample positions on the tray are arranged in an array, and the positions in the middle area are inconvenient for installing or removing adapters, making use even more difficult. Additionally, while adapters for micro-volume blood sample containers achieve automated micro-volume blood sample introduction to some extent, they still do not solve the problem of micro-volume blood sample containers not being automatically transferred or mixed by robotic arms / grippers.

[0005] Therefore, some manufacturers specially customize micro-blood collection tubes that look the same as ordinary sample tubes and have an inner cavity similar to micro-blood sample containers (such as CN218271510U and CN219782559U). However, these specially customized micro-blood collection tubes are not compatible with existing micro-blood sample containers on the market (existing micro-blood sample containers still require traditional adapters to achieve automatic sample injection), and also increase the types of consumables in hospitals, increasing the difficulty and cost of consumable management.

[0006] Therefore, there is a need to provide an adapter tube and analysis system for a micro-blood sample container, which can transform the micro-blood sample container into a sample tube similar to a whole blood sample tube, so as to facilitate the automated detection of micro-blood samples. Summary of the Invention

[0013] Furthermore, the adapter tube body includes an upper tube body and a lower tube body, and the clearance groove and the card interface are disposed on the upper tube body.

[0014] Furthermore, the upper tube body also includes a guide groove disposed on the inner wall of the upper tube body, the guide groove being used to guide the first buckle to move toward the card interface during the assembly process.

[0015] Furthermore, the weight of the lower tube body / the weight of the upper tube body is greater than or equal to 0.8, preferably greater than or equal to 1, and more preferably greater than or equal to 1.2.

[0018] Furthermore, the adapter tube also includes a color mark, which is carried on the adapter tube body and / or the adapter component. Preferably, the color mark is selected from any one of red, purple, yellow, green, gray, blue, and black.

[0019] Furthermore, the clamping arm extends downward from the base and is inclined toward the central axis of the adapter tube.

[0020] Furthermore, the adapter tube also includes an abutment structure; the abutment structure is located at the connection between the upper tube body and the lower tube body.

[0043] like Figure 1 As shown, an adapter tube 10 for a micro-blood sample container is provided, transforming the micro-blood sample container into a sample tube similar to a whole blood sample tube. It includes an adapter tube body 11 and an adapter assembly 12. The adapter tube body 11 includes an upper tube body 111 and a lower tube body 112. The adapter tube body has a receiving cavity for receiving the micro-blood sample container. This receiving cavity is divided into an upper receiving cavity and a lower receiving cavity, with the upper receiving cavity corresponding to the upper tube body 111 and the lower receiving cavity corresponding to the lower tube body 112.

[0044] like Figure 2As shown, the adapter component 12 has a base 121, two first latches 122, and four clamping arms 123. Both first latches 122 are disposed on the base 121, and the four clamping arms 123 are also disposed on the base 121. The first latches 122 and the clamping arms 123 are disposed at different positions on the base 121, but are disposed on the same side of the base 121.

[0045] like Figure 3 As shown, the upper tube 111 includes a clearance groove 13 and a locking interface 14. The adapter component 12 is connected to the adapter tube by connecting to the upper tube 111. When the adapter component 12 is connected to the upper tube 111, the first latch 122 engages in the locking interface 14, and a portion of the clamping arm 123 is accommodated in the clearance groove 13. The clamping arm 123 is used to clamp the outer wall of the micro-blood sample container.

[0046] In a preferred embodiment, such as Figure 4 As shown, the upper tube body 111 also includes a guide groove 15. The guide groove 15 is disposed on the inner wall of the upper tube body, extends downward from the upper end of the upper tube body 111 to the card interface 14, and is used to guide the first buckle 122 to move toward the card interface during the assembly process.

[0047] In some optional embodiments, the number of first latches 122 can be 1, 3, 4, 6, etc.; the number of clamping arms 123 can be 2, 3, 6, etc. Typically, the number of clearance slots 13 provided in the upper tube 111 is the same as the number of clamping arms 123 provided in the adapter component 12; however, in some optional embodiments, the number of clearance slots 13 provided in the upper tube 111 can be greater than the number of clamping arms 123 provided in the adapter component 12. Similarly, typically, the number of card interfaces 14 provided in the upper tube 111 is the same as the number of first latches 122 provided in the adapter component 12; however, in some optional embodiments, the number of card interfaces 14 provided in the upper tube 111 can be greater than the number of first latches 122 provided in the adapter component 12.

[0048] To better transform the micro-blood sample container into a sample tube similar to a whole blood sample tube, facilitating automated detection of micro-blood samples and allowing for seamless mixing with whole blood sample tubes, this embodiment features a specially designed adapter tube 10 for the micro-blood sample container.

[0049] Since the micro-blood sample container is assembled in the upper area of ​​the adapter tube 10, in order to avoid unstable placement and back-and-forth shaking, the weight of the lower tube body 112 of the adapter tube body 11 / the weight of the upper tube body 111 is greater than or equal to 0.8, preferably greater than or equal to 1, and more preferably greater than or equal to 1.2.

[0050] Furthermore, in a preferred embodiment, such as Figure 5 As shown, the outer diameter d2 of the lower tube 112 of the adapter tube 11 is 12mm-13.5mm (preferably 13mm), and the outer diameter d1 of the upper tube 111 of the adapter tube 11 is 15mm-18mm (preferably 16.5mm). Generally, in whole blood sample tube carriers, such as sample racks and sample trays, the inner diameter of the receiving hole for placing the sample tube is about 13mm-15mm. Therefore, setting the outer diameter d2 of the lower tube 112 to 12mm-13.5mm, slightly smaller than the inner diameter of the receiving hole (the difference is about 0.5mm-1mm), ensures that the adapter tube 10 can be smoothly inserted into the receiving hole while maintaining a certain clamping force to prevent tipping or shaking. In a more preferred embodiment, the inner diameter d3 of the lower tube 112 is 6mm-10mm.

[0051] Meanwhile, sample tube clamping devices typically achieve automated transfer or mixing of sample tubes by clamping the upper region (cap region). Therefore, to enable arbitrary mixing of the adapter tube 10 for micro-volume blood sample containers and whole blood sample tubes, and to reduce the configuration settings of the analysis system (e.g., reducing the clamping configuration parameters separately set for micro-volume blood sample containers), the outer diameter d1 of the upper tube body 111 is set to 15mm-18mm, which is comparable to the outer diameter of the cap of the whole blood sample tube. This setting ensures that the operation of the robotic arm grasping the adapter tube 10 is consistent with the operation of grasping the whole blood sample tube. Furthermore, the adapter tube, placed in a support device (such as a sample rack or sample tray), will not interfere with adjacent sample tubes or the analysis system's operation on adjacent sample tubes.

[0052] Furthermore, in another preferred embodiment, such as Figure 5 As shown, the length L1 of the lower tube 112 of the adapter tube 11 is 50mm-90mm. Taking a 13×75mm whole blood sample tube as an example (the total height including the cap is approximately 83mm), the depth of the corresponding receiving hole of the matching sample holder is generally designed to be 65mm; taking a 13×100mm whole blood sample tube as an example (the total height including the cap is approximately 110mm), the depth of the corresponding receiving hole of the matching sample holder is generally designed to be 90mm. Therefore, setting the length L1 of the lower tube 112 to 50mm-90mm ensures that the adapter tube 10 can be used with the supporting device (such as a sample holder, sample tray, etc.) of the whole blood sample tube.

[0053] In a more preferred embodiment, the length of the upper tube 111 of the adapter tube 11 is L2, and the total length of the adapter tube 11 is L3 (L3 = L1 + L2), wherein L3 is set to 70mm-110mm, and L2 is set to 20mm-45mm.

[0054] On the one hand, the total length of the whole blood sample tube including the cap is approximately 83mm-110mm, and the total length of the adapter tube equipped with the micro-blood sample container should also be between 83mm-110mm. Considering that the micro-blood sample container may extend beyond the top of the adapter tube, the total length L3 of the adapter tube body 11 is set to 70mm-110mm.

[0055] On the other hand, the length of the micro-blood sample tube is approximately 30-45 mm, and the micro-blood sample container is mainly housed in the upper cavity corresponding to the upper tube body 111. Therefore, the length of the upper tube body 111 should be comparable to the length of the micro-blood sample tube. Meanwhile, considering that a portion of the micro-blood sample container may extend beyond the upper part of the adapter tube, the length L2 of the upper tube body 111 is set to 20 mm-45 mm.

[0056] In an optional embodiment, the adapter tube 10 further includes color markings carried on the adapter tube body 11 and / or adapter component 12. The color markings are selected from any one of red, purple, yellow, green, gray, blue, and black. The color markings can be used to distinguish different detection purposes, for example: red corresponds to routine biochemical and immunological tests; black corresponds to erythrocyte sedimentation rate (ESR) tests; purple corresponds to complete blood count (CBC) tests; and blue corresponds to coagulation function tests.

[0057] In this embodiment, the adapter component 12 has four clamping arms 123, and the base 121 is annular, with the four clamping arms 123 evenly distributed along the annular base 121. Figure 2 and 6 As shown, the outer diameter D1 of the base 121 is 15mm-18mm, preferably D1 = d1. The clamping arms 123 extend downward from the base 121 and are inclined towards the center (inclined towards the central axis of the adapter tube). In the free state, the diameter of the inscribed circle at the end of the four clamping arms 123 is D2, which is 4mm-10mm. The inclination angle of the clamping arms 123 (the angle between the clamping arm 123 and the central axis of the adapter tube) is 5°-15°, and the length of the clamping arms is 10mm-20mm.

[0058] In a preferred embodiment, such as Figure 7 and 8 As shown, the adapter tube also includes an abutment structure 18. Figure 7 and Figure 8 (The structure within the red dashed box) The abutment structure is located at the connection between the upper tube 111 and the lower tube 112. The abutment structure 18 is used to abut against at least a portion of the bottom region of the micro-blood sample container. As an example, the abutment structure 18 may be a stepped structure, and / or a raised structure, and / or a groove structure, etc., located at the connection between the upper tube 111 and the lower tube 112.

[0059] like Figure 7As shown, when the bullet head 16 (a type of micro-blood sample container) is assembled into the adapter tube 10 of this application, the bottom of the bullet head abuts against the stepped structure of the lower tube body 112 extending into the upper tube body. Figure 8 As shown, when the Hitachi cup 17 (a type of micro-blood sample container) is assembled into the adapter tube 10 of this application, the bottom of the Hitachi cup abuts against the groove structure at the bottom of the upper tube body 11.

[0060] Figure 9 A schematic diagram of a sample analysis system is provided, such as... Figure 9 As shown, the sample analysis system includes a processor 20, a sample introduction device 30, and a sample analyzer 40.

[0061] A sample analyzer 40 refers to an instrument used to detect and analyze samples to obtain test results. Specifically, it can be a biochemical analyzer, an immunoassay analyzer, a coagulation analyzer, a blood analyzer, or other sample analysis instruments.

[0062] The processor 20 is located outside the instrument containing the components of the sample analyzer 40, but maintains a communicative connection with those components. Alternatively, the processor 20 may be located within the same instrument as the components of the sample analyzer (as part of the sample analyzer).

[0063] Figure 10 This is a schematic diagram of a processor structure. As an example, such as... Figure 10As shown, the processor 20 includes at least a processing component 201, a communication interface 202, a memory 203, and an I / O interface 204. The processing component 201, communication interface 202, memory 203, and I / O interface 204 communicate via a bus 205. The processing component 201 can be a CPU, GPU, FPGA, MCU, or other chip with computing capabilities. The memory 203 contains various computer programs, such as operating systems and application programs, for the processing component 201 to execute, as well as the data required to execute these computer programs. Additionally, during sample analysis, any data requiring local storage (including test result data, quality control data, calibration data, fault information data, maintenance information data, operation information data, etc.) can be stored in the memory 203. The I / O interface 204 can be a serial interface (such as USB, IEEE1394, or RS-232C), a parallel interface (such as SCSI, IDE, or IEEE1284), or an analog signal interface (such as a D / A converter or A / D converter). The I / O interface 204 can be connected to input devices consisting of a keyboard, mouse, touchscreen, or other control buttons, allowing users to directly input data into the processor 20. Additionally, the I / O interface 204 can be connected to a display with display capabilities, such as an LCD screen, touchscreen, or LED display. The processor 20 can output processed data as image display data to the display for viewing, such as analysis data or instrument operating parameters. The communication interface 202 can be any known communication protocol. The communication interface 202 communicates with the outside world via a network. The processor 20 can transmit data with any device connected through the network via the communication interface 202 using a specific communication protocol.

[0064] The sample introduction device 30 is used at least to transport the sample container carried in the sample container carrier. The sample container carrier can be a sample rack, sample tray, or sample holder, and is provided with at least one receiving hole for carrying the sample container. The sample container can be a whole blood sample tube (i.e., a common venous blood sample tube) or an adapter tube equipped with a micro-volume blood sample container as described in this application. In this application, the sample container carrier no longer needs to use an additional adapter device and can be directly used to carry the adapter tube equipped with a micro-volume blood sample container as described in this application.

[0065] In this embodiment, the adapter tube equipped with a micro-volume blood sample container and the whole blood sample tube can be arbitrarily mixed and matched in the sample container carrier for use.

[0066] like Figure 9 As shown, the sample analysis system also includes a sampling device 50 and a sample transfer device 60. The sampling device 50 is used to aspirate the sample from the micro-volume blood sample container; the sample transfer device 60 is used to transfer the sample container and / or mix the sample.

[0067] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this application, and these modifications or substitutions should all be covered within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
