Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to a sample analysis device. Background Technology

[0002] Sample analysis devices utilize biological, chemical, and physical principles to detect human or animal serum, plasma, urine, and other bodily fluids containing analytes, in order to analyze the quantity of certain substances or specific functions within the body. Sample analysis devices typically consist of a reagent stand and reagent containers. The reagent containers include two sub-containers for holding different reagents. The reagent stand carries and transports the reagent containers to designated locations to facilitate operations such as aspiration, sample addition, mixing, and measurement. During the movement of the reagent containers on the reagent stand, the two sub-containers need to be disassembled and reassembled to achieve different functions.

[0003] In related technologies, the separate disassembly and assembly mechanism in the sample analyzer is used to disassemble and combine the two sub-reagent containers. Its structure is relatively complex and its cost is relatively high. Utility Model Content

[0004] This application provides a sample analysis device, which aims to solve the problem that the separate disassembly and assembly mechanism in the sample analysis device of the related art is relatively complex and costly in terms of disassembly and assembly of two sub-reagent containers.

[0005] This application provides a sample analysis device, the sample analysis device comprising:

[0006] A sample preparation mechanism for preparing reaction solutions using reaction reagents and test samples;

[0007] A testing organization is used to perform project testing on the reaction solution to obtain testing information. The reaction reagent is contained in a reagent container, which includes a first sub-reagent container and a second sub-reagent container. A reagent stand is used to contain the reagent container.

[0008] A disassembly and assembly mechanism is used to drive the first sub-reagent container and / or the second sub-reagent container to move the first sub-reagent container relative to the second sub-reagent container along the installation direction, so as to connect the first sub-reagent container and the second sub-reagent container to form the reagent container;

[0009] The disassembly and assembly mechanism is also used to drive the first sub-reagent container and / or the second sub-reagent container to move the first sub-reagent container relative to the second sub-reagent container in the opposite direction of the installation direction, so as to separate the first sub-reagent container and the second sub-reagent container.

[0010] In some embodiments, the disassembly and assembly mechanism includes a first driving portion and a second driving portion spaced apart along the installation direction. The first driving portion is used to abut against the side of the first sub-reagent container opposite to the installation direction and push the first sub-reagent container to move relative to the second sub-reagent container along the installation direction to connect the first sub-reagent container and the second sub-reagent container.

[0011] The second driving part is used to abut against one side of the first sub-reagent container along the installation direction and push the first sub-reagent container to move relative to the second sub-reagent container in the opposite direction of the installation direction, so as to separate the first sub-reagent container and the second sub-reagent container.

[0012] In some embodiments, the installation direction is substantially perpendicular to the height direction of the first sub-reagent container; the installation direction is substantially parallel to the surface of the first sub-reagent container facing the second sub-reagent container.

[0013] In some embodiments, the first driving part is further provided with a first limiting part on one side along the mounting direction, the first limiting part being used to abut against the shoulder of the first sub-reagent container to limit the shaking of the first sub-reagent container; and / or,

[0014] The second driving part is provided with a second limiting part on the side opposite to the installation direction. The second limiting part is used to abut against the shoulder of the first sub-reagent container to limit the shaking of the first sub-reagent container.

[0015] In some embodiments, the first limiting portion and the second limiting portion are respectively used to abut against the two ends of the top of the first sub-reagent container along the installation direction.

[0016] In some embodiments, the disassembly and assembly mechanism includes a slide rail, a drive member, and a transmission structure. The slide rail extends along the installation direction. The drive member includes a first drive portion and a second drive portion. The drive member is slidably mounted on the slide rail. The transmission structure is connected to the drive member and is used to receive driving force and drive the drive member to slide back and forth along the slide rail.

[0017] In some embodiments, the reagent stand includes a fixing part for connecting to the second sub-reagent container to restrict the second sub-reagent container from moving in the mounting direction and in the opposite direction of the mounting direction.

[0018] In some embodiments, the sample analysis apparatus includes a reagent tray for placing the reagent container and a loading port for loading the reagent container; the reagent stand includes a tray and a moving mechanism, the tray for accommodating at least one of the reagent containers and the moving mechanism for driving the tray to move between the loading port and the reagent tray;

[0019] When the tray is positioned between the loading port and the reagent tray, the disassembly mechanism is used to drive the first sub-reagent container and / or the second sub-reagent container to move the first sub-reagent container relative to the second sub-reagent container in the opposite direction of the installation direction, so as to separate the first sub-reagent container and the second sub-reagent container. The sample analysis device further includes a scheduling device for scheduling the first sub-reagent container and / or the second sub-reagent container from the tray to the reagent tray.

[0020] In some embodiments, the scheduling device is further configured to schedule the reagent container placed on the reagent tray to the tray, and the moving mechanism is further configured to drive the tray to the unloading position for unloading the reagent container, so that the reagent container is unloaded from the loading port of the sample analysis device.

[0021] Before the tray moves to the unloading position, the disassembly and assembly mechanism drives the first sub-reagent container and / or the second sub-reagent container to move the first sub-reagent container relative to the second sub-reagent container in the installation direction, so as to connect the first sub-reagent container and the second sub-reagent container to form the reagent container.

[0022] In some embodiments, the first sub-reagent container and the second sub-reagent container of the reagent container have different capacities.

[0023] The sample analysis device provided in this application provides a mechanism for connecting and separating reagent containers. This mechanism drives a first sub-reagent container and / or a second sub-reagent container, causing the first sub-reagent container to move relative to the second sub-reagent container along the installation direction. This connects the first and second sub-reagent containers to form a reagent container, thus achieving reagent container assembly. Simultaneously, a mechanism also drives the first and / or second sub-reagent containers, causing the first sub-reagent container to move relative to the second sub-reagent container in the opposite direction of the installation direction. This separates the first and second sub-reagent containers, thus achieving reagent container disassembly. Therefore, the mechanisms for connecting and separating the first and second sub-reagent containers and the reagent stand can operate independently of each other, eliminating the need for disassembly and assembly of the reagent containers via the reagent stand. This simplifies the structure of the reagent stand and reduces its cost. Attached Figure Description

[0041] This application provides a sample analysis device. The device includes a sample preparation mechanism and a detection mechanism. The sample preparation mechanism prepares a reaction solution using reaction reagents and a sample to be tested. The detection mechanism performs tests on the reaction solution to obtain detection information. The reaction reagents are housed in a reagent container 100, which includes a first sub-reagent container 110 and a second sub-reagent container 120. Different reaction reagents can be contained within the first sub-reagent container 110 and the second sub-reagent container 120. In one embodiment, the first sub-reagent container 110 and the second sub-reagent container 120 contain two different reaction reagents used for the same test item.

[0042] Figure 1 This is a schematic diagram of one embodiment of the reagent stand and disassembly / assembly mechanism of the sample analysis apparatus provided in this application. Figure 1 As shown, the sample analysis device includes a reagent stand 200 and a disassembly / assembly mechanism 300. The reagent stand 200 is used to house the reagent container 100. The disassembly / assembly mechanism 300 is used to disassemble / assemble the reagent container 100, allowing the first sub-reagent container 110 and the second sub-reagent container 120 of the reagent container 100 to be joined or separated.

[0043] In some embodiments, such as Figure 2As shown, the disassembly and assembly mechanism 300 can be used to drive the first sub-reagent container 110 and / or the second sub-reagent container 120, so that the first sub-reagent container 110 moves relative to the second sub-reagent container 120 along the installation direction P, so as to connect the first sub-reagent container 110 and the second sub-reagent container 120 to form a reagent container 100.

[0044] It should be noted that the disassembly and assembly mechanism 300 can drive the first sub-reagent container 110 to move relative to the second sub-reagent container 120 along the installation direction P; alternatively, the disassembly and assembly mechanism 300 can also drive the second sub-reagent container 120 to move relative to the first sub-reagent container 110 in the opposite direction of the installation direction P. In this case, it can also be regarded as the first sub-reagent container 110 moving relative to the second sub-reagent container 120 along the installation direction P. Of course, the disassembly and assembly mechanism 300 can also drive the first sub-reagent container 110 and the second sub-reagent container 120 to move simultaneously, causing the first sub-reagent container 110 to move relative to the second sub-reagent container 120 along the installation direction P.

[0045] like Figure 3 As shown, the disassembly and assembly mechanism 300 is also used to drive the first sub-reagent container 110 and / or the second sub-reagent container 120, so that the first sub-reagent container 110 moves relative to the second sub-reagent container 120 in the opposite direction of the installation direction P, so as to separate the first sub-reagent container 110 and the second sub-reagent container 120.

[0046] It should be noted that the disassembly and assembly mechanism 300 can drive the first sub-reagent container 110 to move relative to the second sub-reagent container 120 in the opposite direction of the installation direction P; alternatively, the disassembly and assembly mechanism 300 can also drive the second sub-reagent container 110 to move relative to the first sub-reagent container 110 in the opposite direction of the installation direction P, which can also be regarded as the first sub-reagent container 110 moving relative to the second sub-reagent container 120 in the opposite direction of the installation direction P. Of course, the disassembly and assembly mechanism 300 can also drive the first sub-reagent container 110 and the second sub-reagent container 120 to move simultaneously, so that the first sub-reagent container 110 moves relative to the second sub-reagent container 120 in the opposite direction of the installation direction P.

[0047] The sample analysis device provided in this application embodiment drives the first sub-reagent container 110 and / or the second sub-reagent container 120 through a disassembly and assembly mechanism 300, causing the first sub-reagent container 110 to move relative to the second sub-reagent container 120 along the installation direction P, thereby connecting the first sub-reagent container 110 and the second sub-reagent container 120 to form a reagent container 100, thus achieving the combination of the reagent container 100. Simultaneously, the disassembly and assembly mechanism 300 also drives the first sub-reagent container 110 and / or the second sub-reagent container 120, causing the first sub-reagent container 110 to move relative to the second sub-reagent container 120 in the opposite direction of the installation direction P, thereby separating the first sub-reagent container 110 and the second sub-reagent container 120, thus achieving the disassembly of the reagent container 100. Therefore, the disassembly and assembly mechanism 300 for the first sub-reagent container 110 and the second sub-reagent container 120 of the reagent container 100 can work independently of the reagent stand 200, without having to disassemble and assemble the reagent container 100 through the reagent stand 200, which helps to simplify the structure of the reagent stand 200 and reduce the cost of the reagent stand 200.

[0048] In some embodiments, the disassembly / reassembly mechanism 300 can be used to drive the first sub-reagent container 110 to move relative to the second sub-reagent container 120 along the mounting direction P, so as to connect the first sub-reagent container 110 and the second sub-reagent container 120. Furthermore, the disassembly / reassembly mechanism 300 can also be used to drive the first sub-reagent container 110 to move in the opposite direction relative to the second sub-reagent container 120 along the mounting direction P, so as to separate the first sub-reagent container 110 from the second sub-reagent container 120.

[0049] like Figures 1 to 3 As shown, the disassembly / assembly mechanism 300 can include a first driving unit 3111 and a second driving unit 3112. The first driving unit 3111 is used to drive the first sub-reagent container 110 to move relative to the second sub-reagent container 120 along the installation direction P, so as to connect the first sub-reagent container 110 and the second sub-reagent container 120. The second driving unit 3112 is used to drive the first sub-reagent container 110 to move in the opposite direction relative to the second sub-reagent container 120 along the installation direction P, so as to separate the first sub-reagent container 110 and the second sub-reagent container 120.

[0050] The driving force applied by the first driving unit 3111 and the second driving unit 3112 to the first sub-reagent container 110 can be a pushing force or a pulling force, as long as it can drive the first sub-reagent container 110 to move relative to the second sub-reagent container 120 in the opposite direction of the installation direction P.

[0051] In some embodiments, the first driving part 3111 and the second driving part 3112 of the disassembly and assembly mechanism 300 can be spaced apart along the installation direction P. The first driving part 3111 is used to abut against the side of the first sub-reagent container 110 opposite to the installation direction P and push the first sub-reagent container 110 to move relative to the second sub-reagent container 120 along the installation direction P, so as to connect the first sub-reagent container 110 and the second sub-reagent container 120. Thus, it is only necessary for the first driving part 3111 to abut against the side of the first sub-reagent container 110 opposite to the installation direction P. The structure of the first driving part 3111 is relatively simple, which helps to reduce the cost of the disassembly and assembly mechanism 300.

[0052] Furthermore, the second drive unit 3112 is used to abut against one side of the first sub-reagent container 110 along the mounting direction P, and push the first sub-reagent container 110 to move relative to the second sub-reagent container 120 in the opposite direction of the mounting direction P, so as to separate the first sub-reagent container 110 and the second sub-reagent container 120. Thus, it is only necessary to enable the second drive unit 3112 to abut against one side of the first sub-reagent container 110 along the mounting direction P. The structure of the second drive unit 3112 is relatively simple, which helps to reduce the cost of the disassembly and assembly mechanism.

[0053] In some embodiments, the installation direction P can be substantially perpendicular to the height direction Z of the first sub-reagent container 110. Thus, the disassembly / reassembly mechanism 300 drives the first sub-reagent container 110 and / or the second sub-reagent container 120, causing the first sub-reagent container 110 to move relative to the second sub-reagent container 120 along the installation direction P or in the opposite direction of the installation direction P. This minimizes the impact of gravity during the connection or separation of the first sub-reagent container 110 and the second sub-reagent container 120, allowing the disassembly / reassembly mechanism 300 to stably contact and push the first sub-reagent container 110 and / or the second sub-reagent container 120 to move.

[0054] Specifically, the mounting direction P can be made substantially parallel to the surface of the first sub-reagent container 110 facing the second sub-reagent container 120. Therefore, when the disassembly / reassembly mechanism 300 drives the first sub-reagent container 110 and / or the second sub-reagent container 120, causing the first sub-reagent container 110 to move relative to the second sub-reagent container 120 along the mounting direction P or in the opposite direction of the mounting direction P, the relative movement of the first sub-reagent container 110 and / or the second sub-reagent container 120 in the thickness direction Y is small, which helps to reduce the space occupied during the connection and separation of the first sub-reagent container 110 and the second sub-reagent container 120.

[0055] like Figures 6 to 8As shown, the first sub-reagent container 110 includes a first side surface 1104 located on its thickness direction Y. The second sub-reagent container 120 includes a second side surface located on its thickness direction Y. The reagent container 100 also includes a splicing structure 130 for connecting the first sub-reagent container 110 and the second sub-reagent container 120. The splicing structure 130 may include a first splicing portion 131 and a second splicing portion 132. The first splicing portion 131 is disposed on the first side surface 1104 of the first sub-reagent container 110, and the second splicing portion 132 is disposed on the second side surface of the second sub-reagent container 120. The first splicing portion 131 is used to splice with the second splicing portion 132 to connect the first sub-reagent container 110 and the second reagent container 120 into a single unit.

[0056] The installation direction P is substantially parallel to the first side surface 1104. The first sub-reagent container 110 can be moved relative to the second sub-reagent container 120 along the installation direction P, causing the first splicing part 131 and the second splicing part 132 to join together, thus connecting the first sub-reagent container 110 and the second sub-reagent container 120 as a single unit. By moving the first sub-reagent container 110 relative to the second sub-reagent container 120 in the opposite direction of the installation direction P, the first splicing part 131 and the second splicing part 132 can be separated, thereby separating the first sub-reagent container 110 and the second sub-reagent container 120.

[0057] In some embodiments, such as Figures 6 to 8 As shown, the first splicing portion 131 can include a first protrusion 1311, and the second splicing portion 132 can include a first groove 1321. The first protrusion 1311 is inserted into the first groove 1321 to splice the first splicing portion 131 and the second splicing portion 132. The first protrusion 1311 is also used to disengage from the first groove 1321 to separate the first splicing portion 131 and the second splicing portion 132. By making the first splicing portion 131 include the first protrusion 1311 and the second splicing portion 132 include the first groove 1321, the structure of the first splicing portion 131 and the second splicing portion 132 can be made relatively simple and easy to process. Moreover, by inserting or disengaging the first protrusion 1311 into or out of the first groove 1321, the first splicing structure 130 and the second splicing structure 130 can be spliced ​​and separated, making the operation very convenient.

[0058] Specifically, the first protrusion 1311 can protrude from the first side surface 1104 to facilitate insertion of the first protrusion 1311 into the corresponding first groove 1321. Additionally, the first groove 1321 can have a first notch 1322 formed at one end of the second sub-reagent container 120 along the length direction X. The first sub-reagent container 110 is used to move relative to the second sub-reagent container 120 along the mounting direction PP, so that the first protrusion 1311 is inserted into the first groove 1321 from the first notch 1322. The mounting direction P is substantially parallel to the first side surface 1104.

[0059] By forming a first groove 1322 at one end of the length direction X of the second sub-reagent container 120 with the first groove 1321, when the first sub-reagent container 110 moves relative to the second sub-reagent container 120 along the installation direction P which is basically parallel to the first side 1104, the first protrusion 1311 can be directly inserted into the first groove 1321 through the first groove 1322, thereby completing the splicing of the first splicing part 131 and the second splicing part 132. The movement direction of the first sub-reagent container 110 relative to the second sub-reagent container 120 is relatively simple, and the operation is more convenient.

[0060] When it is necessary to separate the first sub-reagent container 110 and the second sub-reagent container 120, the first sub-reagent container 110 can be moved in the opposite direction of the installation direction P relative to the second sub-reagent container 120, so that the first protrusion 1311 can be dislodged from the first groove 1321 from the first slot 1322, which is relatively convenient.

[0061] In some embodiments, such as Figure 7 and Figure 8 As shown, the first splicing portion 131 may further include a second groove 1312, and the second splicing portion 132 may further include a second protrusion 1323. The second protrusion 1323 is inserted into the second groove 1312 to splice the first splicing portion 131 and the second splicing portion 132. The second protrusion 1323 is used to disengage from the second groove 1312 to separate the first splicing portion 131 and the second splicing portion 132.

[0062] By including a second groove 1312 in the first splicing part 131 and a second protrusion 1323 in the second splicing part 132, when the second protrusion 1323 is inserted into the second groove 1312, the connection between the first splicing part 131 and the second splicing part 132 can be made more secure, which is beneficial to improving the stability of the connection between the first sub-reagent container 110 and the second sub-reagent container 120.

[0063] The second protrusion 1323 may protrude from the second side surface 1204 to facilitate insertion of the second protrusion 1323 into the corresponding second groove 1312. Alternatively, the second groove 1312 may have a second opening 1313 formed at one end of the first sub-reagent container 110 along the length direction X. The first sub-reagent container 110 is used to move relative to the second sub-reagent container 120 along the installation direction P, so that the second protrusion 1323 is inserted into the second groove 1312 from the second opening 1313. The installation direction P is substantially parallel to the first side surface 1104.

[0064] By forming a second groove 1313 at one end of the length direction X of the first sub-reagent container 110, when the first sub-reagent container 110 moves relative to the second sub-reagent container 120 along the installation direction P which is basically parallel to the first side surface 1104, the second protrusion 1323 can be directly inserted into the second groove 1312 through the second groove 1313, thereby completing the splicing of the first splicing part 131 and the second splicing part 132. The movement direction of the first sub-reagent container 110 relative to the second sub-reagent container 120 is relatively simple, and the operation is more convenient.

[0065] When it is necessary to separate the first sub-reagent container 110 and the second sub-reagent container 120, the first sub-reagent container 110 can be moved in the opposite direction of the installation direction P relative to the second sub-reagent container 120, so that the second protrusion 1323 can be dislodged from the second slot 1313 and the second groove 1312. The operation is very convenient.

[0066] In some embodiments, such as Figures 1 to 3 As shown, the first driving part 3111 can extend along the height direction Z of the reagent container 100, so that after the first driving part 3111 abuts against the side of the first sub-reagent container 110 opposite to the installation direction P, there is a large contact area between the first driving part 3111 and the first sub-reagent container 110, so that the first driving part 3111 can stably push the first sub-reagent container 110 to move along the installation direction P.

[0067] In addition, the second driving part 3112 can be extended along the height direction Z of the reagent container 100, so that after the second driving part 3112 abuts against the first sub-reagent container 110 on one side along the installation direction P, there is a large contact area between the second driving part 3112 and the first sub-reagent container 110, so that the second driving part 3112 can more stably push the first sub-reagent container 110 to move in the opposite direction along the installation direction P.

[0068] In some embodiments, the disassembly / assembly mechanism 300 may further include a connecting portion 3113 connecting the first driving portion 3111 and the second driving portion 3112, the connecting portion 3113 extending along the mounting direction P. One end of the connecting portion 3113 is connected to the first driving portion 3111, and the other end of the connecting portion 3113 is connected to the second driving portion 3112. A receiving space for accommodating the reagent container 100 is formed between the first driving portion 3111 and the second driving portion 3112. Thus, by moving the connecting portion 3113 along the mounting direction P or in the opposite direction of the mounting direction P, the first driving portion 3111 and the second driving portion 3112 can be moved along the mounting direction P or in the opposite direction of the mounting direction P.

[0069] The connecting part 3113 can be integrated with the first driving part 3111 and the second driving part 3112 to improve the strength of the first driving part 3111 and the second driving part 3112.

[0070] In some embodiments, such as Figures 1 to 3 As shown, a first limiting part 3114 may be provided on one side of the first driving part 3111 along the mounting direction P. The first limiting part 3114 is used to abut against the shoulder of the first sub-reagent container 110 to limit the shaking of the first sub-reagent container 110. Thus, when the first driving part 3111 abuts against the side of the first sub-reagent container 110 opposite to the mounting direction P and pushes the first sub-reagent container 110 to move relative to the second sub-reagent container 120 along the mounting direction P, if the first sub-reagent container 110 deflects upward, the first limiting part 3114 can abut against the shoulder of the first sub-reagent container 110 to limit the shaking of the first sub-reagent container 110, so that the first sub-reagent container 110 can move stably along the mounting direction P relative to the second sub-reagent container 120 to the position where it is connected to the second sub-reagent container 120.

[0071] Specifically, the first limiting part 3114 can be located on one side of the first driving part 3111 along the mounting direction P, and the first limiting part 3114 is located on the side of the connecting part 3113 facing the receiving space. When the first driving part 3111 abuts against the side of the first sub-reagent container 110 opposite to the mounting direction P, the first limiting part 3114 is located on one side of the first sub-reagent container 110 in the bottom to top direction, so that the first limiting part 3114 can abut against the shoulder of the first sub-reagent container 110.

[0072] Specifically, the first sub-reagent container 110 includes a top surface 1101 and a bottom surface 1103 disposed opposite to each other. The top surface 1101 of the first sub-reagent container 110 has a pipette port 1102, through which reaction reagents can be injected into the first sub-reagent container 110 and also through which reaction reagents can be removed from the first sub-reagent container 110. The first limiting part 3114 is used to abut against the top of the pipette port 1102 to limit the shaking of the first sub-reagent container 110.

[0073] Of course, the first limiting part 3114 may also abut against other parts of the first sub-reagent container 110 to limit the shaking of the first sub-reagent container 110.

[0074] Similarly, as Figures 1 to 3 As shown, a second limiting part 3115 may be provided on the side of the second driving part 3112 opposite to the installation direction P. The second limiting part 3115 is used to abut against the shoulder of the first sub-reagent container 110 to limit the shaking of the first sub-reagent container 110.

[0075] Therefore, when the second driving part 3112 abuts against the first sub-reagent container 110 on one side along the mounting direction P and pushes the first sub-reagent container 110 to move relative to the second sub-reagent container 120 in the opposite direction of the mounting direction P, if the first sub-reagent container 110 deflects upward, the second limiting part 3115 can abut against the shoulder of the first sub-reagent container 110 to limit the first sub-reagent container 110, restrict the shaking of the first sub-reagent container 110, and make the first sub-reagent container 110 move stably relative to the second sub-reagent container 120 in the opposite direction of the mounting direction P to a position separated from the second sub-reagent container 120.

[0076] Specifically, the second limiting part 3115 can be located on one side of the second driving part 3112 along the mounting direction P, and the second limiting part 3115 is located on the side of the connecting part 3113 facing the receiving space. When the second driving part 3112 abuts against one side of the first sub-reagent container 110 along the mounting direction P, the second limiting part 3115 is located on one side of the first sub-reagent container 110 in the bottom to top direction, so that the second limiting part 3115 can abut against the shoulder of the first sub-reagent container 110.

[0077] Of course, the second limiting part 3115 can also abut against other parts of the first sub-reagent container 110 to limit the shaking of the first sub-reagent container 110.

[0078] In some embodiments, the first limiting portion 3114 and the second limiting portion 3115 may be used to abut against both ends of the top of the first sub-reagent container 110 along the mounting direction P. Thus, when the first driving portion 3111 abuts against the side of the first sub-reagent container 110 opposite to the mounting direction P and pushes the first sub-reagent container 110 to move relative to the second sub-reagent container 120 along the mounting direction P, the first limiting portion 3114 abuts against the end of the top of the first sub-reagent container 110 opposite to the mounting direction P, providing a better restraining effect on the shaking of the first sub-reagent container 110.

[0079] When the second driving part 3112 abuts against one side of the first sub-reagent container 110 along the installation direction P and pushes the first sub-reagent container 110 to move relative to the second sub-reagent container 120 in the opposite direction of the installation direction P, the second limiting part 3115 abuts against one end of the top of the first sub-reagent container 110 along the installation direction P, which has a better limiting effect on the shaking of the first sub-reagent container 110.

[0080] In some embodiments, such as Figures 1 to 3As shown, the disassembly and assembly mechanism 300 may include a slide rail 310, a drive member 311, and a transmission structure (not shown in the figure). The slide rail 310 extends along the installation direction P. The drive member 311 includes a first drive part 3111 and a second drive part 3112. The drive member 311 is slidably mounted on the slide rail 310. The transmission structure is connected to the drive member 311. The transmission structure is used to receive driving force and drive the drive member 311 to slide back and forth along the slide rail 310.

[0081] Therefore, when the transmission structure receives driving force, it can drive the driving component 311 to slide along the slide rail 310, causing the first driving part 3111 and the second driving part 3112 to move along the installation direction P or in the opposite direction of the installation direction P, thereby pushing the first sub-reagent container 110 to move along the installation direction P or in the opposite direction of the installation direction P, so that the first sub-reagent container 110 can be connected or separated from the second sub-reagent container 120. Moreover, the disassembly and assembly mechanism 300 has a relatively simple structure, low cost, and is easy to form a modular structure, which helps to reduce the overall cost of the sample analysis device.

[0082] The transmission structure can be a lead screw, telescopic rod, or any other structure capable of receiving driving force and driving the drive component 311 to reciprocate along the slide rail 310; there are no restrictions here. The driving force can come from the drive motor, hydraulic cylinder, pneumatic cylinder, or other power components of the sample analysis device; there are no restrictions here.

[0083] In some embodiments, such as Figure 4 and Figure 5 As shown, the reagent stand 200 can include a fixing part 211 for connection with the second sub-reagent container 120, thereby limiting the movement of the second sub-reagent container 120 along the mounting direction P and in the opposite direction of the mounting direction P. Thus, when the disassembly / reassembly mechanism 300 drives the first sub-reagent container 110 to move along the mounting direction P or in the opposite direction of the mounting direction P, the fixing part 211 can limit the second sub-reagent container 120, preventing the second sub-reagent container 120 from moving with the first sub-reagent container 110. This facilitates the faster movement of the first sub-reagent container 110 relative to the second sub-reagent container 120 to a position where it is connected to or separated from the second sub-reagent container 120.

[0084] like Figure 1 , Figure 4 and Figure 5As shown, the reagent stand support includes a tray 210 for accommodating at least one reagent container 100. A fixing part 211 is located at the bottom of the tray 210 and includes a limiting groove 2111 for accommodating the bottom mounting of a second sub-reagent container 120 and restricting the second sub-reagent container 120 from moving along the mounting direction P and in the opposite direction of the mounting direction P. The fixing part 211 includes limiting surfaces located on both sides of the limiting groove 2111 along the mounting direction P. These two limiting surfaces abut against the second sub-reagent container 120 within the limiting groove 2111 to restrict the second sub-reagent container 120 from moving along the mounting direction P and in the opposite direction of the mounting direction P.

[0085] In addition, the bottom of the tray 210 may be provided with a guide groove 2112, which is used to accommodate the bottom of the first sub-reagent container 110 and guide the movement of the first sub-reagent container 110 along the installation direction P and the opposite direction of the installation direction P, so that the first sub-reagent container 110 can be more accurately connected or separated from the second sub-reagent container 120.

[0086] In some embodiments, the reagent stand 200 can be used to house a plurality of reagent containers 100. The plurality of reagent containers 100 housed in the reagent stand 200 are sequentially distributed along the thickness direction Y of the reagent containers 100. The disassembly / separation mechanism 300 can flexibly connect and separate the first sub-reagent container 110 and the second sub-reagent container 120 of one or more of the reagent containers 100.

[0087] Specifically, the tray 210 includes multiple pairs of guide grooves 2112 and limiting grooves 2111. The multiple pairs of guide grooves 2112 and limiting grooves 2111 are distributed sequentially along the thickness direction Y of the reagent container 100. Each guide groove 2112 is used to accommodate the bottom of the first sub-reagent container 110, and each limiting groove 2111 is used to accommodate the bottom of the second sub-reagent container 120.

[0088] In some embodiments, the sample analysis apparatus may include a reagent tray (not shown) for placing reagent containers 100, and a loading port (not shown) for loading reagent containers 100. The reagent stand 200 includes a tray 210 for accommodating at least one reagent container 100, and a moving mechanism 220 for driving the tray 210 to move between the loading port and the reagent tray.

[0089] The sample analysis device also includes a scheduling device (not shown in the figure). When the moving mechanism 220 drives the tray 210 to approach the reagent tray, the scheduling device is used to schedule the first sub-reagent container 110 and / or the second sub-reagent container 120 from the tray 210 to the reagent tray, so that the sample analysis device can take the sample to be tested and prepare the reaction solution from the reaction reagents in the first sub-reagent container 110 and / or the second sub-reagent container 120 from the reagent tray.

[0090] In some embodiments, when the tray 210 is between the loading port and the reagent tray, the disassembly / separation mechanism 300 can be used to drive the first sub-reagent container 110 and / or the second sub-reagent container 120, causing the first sub-reagent container 110 to move relative to the second sub-reagent container 120 in the opposite direction of the mounting direction P, thereby separating the first sub-reagent container 110 and the second sub-reagent container 120. Thus, before the moving mechanism 220 drives the tray 210 closer to the reagent tray and the scheduling device schedules the first sub-reagent container 110 and / or the second sub-reagent container 120 from the tray 210 to the reagent tray, the disassembly / separation mechanism 300 can first separate the first sub-reagent container 110 and the second sub-reagent container 120 of the reagent container 100 housed in the tray 210, typically before the scheduling device schedules the first sub-reagent container 110 and the second sub-reagent container 120 to the reagent tray for storage.

[0091] In some embodiments, the scheduling device can also be used to schedule the reagent container 100 placed on the reagent tray to the tray 210 so that when the sample analysis device stops working for a long time, the reagent container 100 can be scheduled to the tray 210, and the tray 210 can be moved to a position close to the loading port by the moving mechanism 220 so that the reagent container 100 in the tray 210 can be taken out from the loading port and refrigerated to avoid the reaction reagent in the reagent container 100 being destroyed by high temperature.

[0092] The moving mechanism 220 is also used to drive the tray 210 to the unloading position of the unloading reagent container 100 so that the reagent container 100 is unloaded from the loading port of the sample analysis device, so as to facilitate the removal of the reagent container 100 from the loading port of the sample analysis device.

[0093] In some embodiments, before the tray 210 moves to the unloading position, the disassembly / engagement mechanism 300 drives the first sub-reagent container 110 and / or the second sub-reagent container 120, causing the first sub-reagent container 110 to move relative to the second sub-reagent container 120 along the mounting direction P, thereby connecting the first sub-reagent container 110 and the second sub-reagent container 120 to form reagent container 100. Thus, before reagent container 100 is removed from the loading port of the sample analysis device, the disassembly / engagement mechanism connects the first sub-reagent container 110 and the second sub-reagent container 120 of reagent container 100 housed in the tray 210, ensuring that the reaction reagents in the first sub-reagent container 110 and the second sub-reagent container 120 are from the same batch, which helps improve the analytical accuracy of the sample analysis device.

[0094] In some embodiments, the sample analysis device may further include an identification component for identifying the identification information of the first sub-reagent container 110 and the second sub-reagent container 120, and pairing the first sub-reagent container 110 and the second sub-reagent container 120 according to the identification information, which is beneficial to ensure that the reaction reagents in the first sub-reagent container 110 and the second sub-reagent container 120 of the reagent container 100 are from the same batch.

[0095] The identification component can be a camera or other component capable of identifying the identification information on the first sub-reagent container 110 and the second sub-reagent container 120, and there are no restrictions on this. Furthermore, the identification information on the first sub-reagent container 110 and the second sub-reagent container 120 can be a barcode, QR code, etc., and there are no restrictions on this.

[0096] In some embodiments, the first sub-reagent container 110 and the second sub-reagent container 120 of the reagent container 100 may have different capacities, so as to inject different volumes of reaction reagents into the first sub-reagent container 110 and the second sub-reagent container 120, so as to combine them to form reagent containers 100 of different specifications.

[0097] Among them, such as Figure 7 As shown, a first indentation 1109 can be provided on the surface of the first sub-reagent container 110 to limit the volume of the first sub-reagent container 110. It can be understood that by providing the first indentation 1109 on the surface of the first sub-reagent container 110, a protruding structure can be formed on the inner surface of the first sub-reagent container 110 while keeping the wall thickness of the first sub-reagent container 110 unchanged. This protruding structure will occupy a part of the internal space of the first sub-reagent container 110, thereby limiting the volume of the first sub-reagent container 110.

[0098] Similarly, as Figure 8 As shown, a second indentation 1205 may be provided on the surface of the second sub-reagent container 120 to limit the volume of the second sub-reagent container 120.
