Description

Technical Field

[0001] This application relates to the field of medical device technology, and more particularly to a sample processing device. Background Technology

[0002] Existing sample processing devices do not secure the containers holding the samples. When the samples in the containers are shaken and mixed, the containers are prone to shifting or tilting during the shaking process because they are not secured. This is not conducive to the uniform mixing of the samples, which affects the accuracy and reliability of subsequent sample testing. Furthermore, the shifting or tilting of the containers can easily cause the samples to spill out, resulting in sample damage or even contamination of the device and the surrounding environment. Utility Model Content

[0044] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with specific embodiments and the accompanying drawings.

[0045] It should be noted that, unless otherwise defined, the technical or scientific terms used in the embodiments of this application should have the ordinary meaning understood by one of ordinary skill in the art to which this application pertains. The terms "first," "second," and similar terms used in the embodiments of this application do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as "comprising" or "including" mean that the element or object preceding the word encompasses the elements or objects listed after the word and their equivalents, without excluding other elements or objects. Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are only used to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0046] In the field of biochemical testing, sample processing and analysis are crucial steps. Traditional sample processing methods often involve multiple steps, including sample mixing, fixation, and subsequent testing and analysis. In the testing of blood samples, because blood is prone to clotting, coagulated blood samples cannot be used for accurate biochemical or hematological analysis, leading to distorted test results. Therefore, an anticoagulant needs to be added inside the blood storage container (e.g., test tube). This necessitates mixing the collected blood with the anticoagulant to ensure sample stability and homogeneity.

[0047] However, traditional blood sample processing devices are not convenient for securing the containers holding the samples. When the samples in the containers are shaken and mixed, the containers are not secured, which makes it easy for them to move or tilt during the shaking process. This is not conducive to the uniform mixing of the samples, which affects the accuracy and reliability of subsequent sample testing. Furthermore, the movement or tilting of the containers can easily cause the samples to spill out, resulting in sample damage or even contamination of the device and the surrounding environment.

[0048] Therefore, how to fix the container holding the sample is an urgent problem to be solved.

[0049] Based on this, see Figure 1 , Figure 2 and Figure 3 As shown, this application provides a sample processing apparatus, including:

[0050] The container rack 1 has at least one opening 14 for placing a container 3, which is used to hold a sample;

[0051] At least one fixing unit 2 is connected to the container rack 1, and each fixing unit 2 corresponds to one of the openings 14. The fixing unit 2 is used to clamp the container 3 in the corresponding opening 14.

[0052] Each of the fixed units 2 includes:

[0053] The rotating part 21, located inside the container frame 1 and rotatable relative to the container frame 1, is configured to rotate in a direction away from the container 3 when squeezed by the bottom of the container 3.

[0054] The clamping part 22 is connected to the rotating part 21 and is configured to clamp the container 3 under the drive of the rotating part 21.

[0055] Specifically, the container rack 1 is used to hold the container 3, which can be a test tube, flask, conical flask, etc., used to hold samples. The container rack 1 has at least one opening 14 for placing the container 3. In actual use, the container 3 is placed on the container rack 1 after passing through the opening 14.

[0056] The container rack 1 may include a first main board 11, a second main board 12, and a third main board 13 arranged sequentially from bottom to top, and the first main board 11, the second main board 12, and the third main board 13 are connected by a side plate 15. The second main board 12 and the third main board 13 are each provided with a through hole, and the opening 14 of the third main board 13 has a groove, and the position of the through hole corresponds to the position of the groove.

[0057] When placing the container 3, the bottom of the container 3 passes through the through holes on the third main board 13 and the second main board 12 in sequence, and then enters the groove on the first main board 11. The first main board 11 provides support for the bottom of the container 3. The second main board 12 and the third main board 13 restrict the upper and middle parts of the container 3 to prevent the container 3 from falling or tipping over from the container rack 1.

[0058] However, since the container rack 1 needs to accommodate containers 3 of various sizes, the dimensions of the opening 14, through holes, and grooves are all much larger than the outer diameter of the container 3. Although they can restrict the container 3 to a certain extent and prevent it from falling or tipping over from the container rack 1, they cannot provide a tight fixation for the container 3. Therefore, when the container 3 is subjected to a force that causes it to vibrate or shake, the container 3, which is not tightly fixed, may tilt, causing the sample inside the container 3 to spill out or the sample to not be mixed evenly, thus affecting the subsequent detection of the sample.

[0059] Therefore, in this application, a fixing unit 2 is provided. At least one fixing unit 2 is provided, and the number of fixing units 2 is the same as the number of openings 14. Each fixing unit 2 corresponds to one opening 14, and the fixing unit 2 is used to clamp the container 3 in the corresponding opening 14.

[0060] The fixing unit 2 is connected to the container frame 1 to ensure the stability of the fixing unit 2 and to ensure that the position of the fixing unit 2 will not shift during vibration or shaking.

[0061] Each of the fixing units 2 includes a rotating part 21 and a clamping part 22. The rotating part 21 is located inside the container rack 1 and can rotate relative to the container rack 1. Specifically, the rotating part 21 may be located between the first main board 11 and the second main board 12, and at least part of the rotating part 21 is located below the container 3. In this way, when the container 3 containing the sample is placed into the container rack 1 through the opening 14, the bottom of the container 3 will exert a squeezing force on the rotating part 21, and the rotating part 21 will rotate away from the container 3 when squeezed by the bottom of the container 3.

[0062] The clamping part 22 is connected to the rotating part 21. When the rotating part 21 is squeezed by the bottom of the container 3 and rotates away from the container 3, the rotating part 21 will drive the clamping part 22 to move closer to the container 3 until it clamps the container 3. In this way, the clamping part can automatically clamp the container 3 without the user's manual operation, so as to fix the container 3.

[0063] In practice, when container 3 is placed into container rack 1 through opening 14, the bottom of container 3 applies a squeezing action to rotating part 21. When squeezed by the bottom of container 3, rotating part 21 rotates away from container 3. The rotating part 21 drives clamping part 22 to move closer to container 3 until it clamps container 3. Thus, when container 3 is placed into container rack 1 and rotating part 21 is squeezed, clamping part 22 can automatically clamp container 3 to fix it. This ensures that when container 3 and the sample inside container 3 are shaken and vibrated in the future, the clamped container 3 will not tilt. It also ensures that the sample inside container 3 can be mixed evenly and will not overflow. Thus, without manual operation by the user, clamping part can automatically clamp container 3 to fix it.

[0064] When the container 3 is lifted so that the rotating part 21 is no longer squeezed, the rotating part 21 returns to its state before being squeezed under the action of the reaction force. That is, the rotating part 21 rotates in the opposite direction towards the container 3. The rotating part 21 rotates in the opposite direction and drives the clamping part 22 to move away from the container 3, so that the clamping part 22 leaves the container 3 and no longer clamps and fixes the container 3. In this way, the clamping part can release the container 3 without the user's manual operation, so that the container 3 is no longer fixed.

[0065] In this application, when container 3 is placed in container rack 1 and the rotating part 21 is squeezed, the rotating part 21 is triggered to rotate. The rotating part 21 drives the clamping part 22 to clamp container 3, thereby clamping and fixing container 3. The clamped container 3 will not tilt or shift even when shaken or vibrated, ensuring that the sample inside container 3 can be mixed evenly and will not overflow. This ensures the uniformity of sample mixing, which is beneficial for subsequent sample monitoring and ensures that the entire device and the surrounding environment will not be contaminated. Furthermore, the clamping process of the clamping part 22 clamping container 3 does not require manual operation by the user; the clamping part can automatically clamp container 3, improving the ease of use of the entire device.

[0066] In some embodiments, see Figure 4 , Figure 5 and Figure 6As shown, each of the fixing units 2 further includes two fixing parts 24 spaced apart along the first direction. Both fixing parts 24 are fixed to the container frame 1 and both fixing parts 24 are rotatably connected to the rotating part 21.

[0067] Specifically, the first direction is Figure 5 In the direction indicated by Y, each fixing unit 2 further includes two fixing parts 24 spaced apart along a first direction, both fixing parts 24 being fixed to the container rack 1. Both fixing parts 24 can be fixedly connected to the first main board 11 of the container rack 1. Each fixing part 24 can include two fixing seats 241 spaced apart along a second direction, where the second direction is... Figure 5 The X direction in the equation.

[0068] Both of the fixed parts 24 are rotatably connected to the rotating part 21. Thus, the fixed parts 24, which are fixedly connected to the container frame 1, can support the rotating part 21, ensuring the rotational stability of the rotating part 21, preventing the rotating part 21 from shifting its position during rotation, and ensuring that the rotating part 21 can rotate away from the container 3 when squeezed by the bottom of the container 3 without shifting or shaking its position.

[0069] In some embodiments, see continue to see Figure 5 , Figure 6 and Figure 7 The rotating part 21 includes two rotating members 211 spaced apart along the first direction. Each rotating member 211 corresponds to one of the fixed parts 24. Each rotating member 211 includes:

[0070] The rotating rod 2111 is rotatably connected to the corresponding fixed part 24;

[0071] The rotating plate 2112 includes a fixed end 21121 and a free end 21122. The fixed end 21121 is fixed to the rotating rod 2111, and the free end 21122 is configured to rotate in a direction away from the container 3 when squeezed by the bottom of the container 3.

[0072] Gear 2113 is fixed at both ends of the rotating rod 2111.

[0073] Specifically, the rotating rod 2111 is rotatably connected to the corresponding fixed part 24, wherein the two ends of the rotating rod 2111 correspond to the two fixed seats 241 in the corresponding fixed part 24, and the end of each rotating rod 2111 is rotatably connected to a fixed seat 241. In this way, the two fixed seats 241 in a fixed part 24 can be connected to both ends of the rotating rod 2111, which can ensure the stability of the rotating rod 2111 during rotation and ensure that the positions of the two ends of the rotating rod 2111 will not shift during rotation.

[0074] The rotating plate 2112 includes a fixed end 21121 and a free end 21122. The fixed end 21121 is fixed to the rotating rod 2111, and the free end 21122 is disposed away from the rotating rod 2111.

[0075] like Figure 7 As shown, when the rotating plate 2112 is not squeezed by the bottom of the container 3, the two rotating plates 2112 of the two rotating parts 21 of each rotating part 21 are arranged parallel to the first main plate 11 and located above the first main plate 11. The free ends 21122 of the two rotating plates 2112 can be in direct contact or have a certain gap, but they are not fixed together.

[0076] As container 3 enters container rack 1 through opening 14 and passes sequentially through third main plate 13 and second main plate 12, preparing to descend to first main plate 11, the bottom of the descending container 3 will touch and press downward against rotating plate 2112. The free end 21122 of rotating plate 2112 will rotate away from container 3 when pressed by the bottom of container 3 (e.g., ...). Figure 6 As shown, the rotating plate 2112 drives the rotating rod 2111 fixed thereto to rotate together, and the rotating rod 2111 drives the two gears 2113 fixed at both ends to rotate together. In this way, the entire rotating part 21 can rotate automatically under the squeezing action of the bottom of the container 3 without the need for manual operation by the user, thus improving the convenience of use of the entire device.

[0077] Furthermore, such as Figure 7 As shown, each of the rotating plates 2112 has a receiving hole 21123. The area of ​​the hole formed by the two receiving holes 21123 on the two rotating plates 2112 is smaller than the area of ​​the bottom of the container 3. This ensures that the bottom of the container 3 can exert a squeezing force on the rotating plate 2112 to make it rotate. At the same time, the receiving hole 21123 provides space for the bottom of the container 3, ensuring that the bottom of the container 3 can be placed into the groove on the first main plate 11 after the rotating plate 2112 rotates, thus avoiding interference between the rotating plate 2112 and the bottom of the container 3.

[0078] In some embodiments, see continue to see Figure 3, Figure 5 and Figure 7 As shown, each of the fixing units 2 further includes two connecting portions 23 spaced apart along a second direction, which intersects the first direction. Each connecting portion 23 is connected to at least one of the rotating portions 21. Each connecting portion 23 includes:

[0079] The slide rail 232 is fixed to the container rack 1;

[0080] The slider 231 is slidably connected to the slide rail 232. The slider 231 is provided with a rack 2311, which meshes with the gear 2113.

[0081] The traction member 233 is connected at one end to the slider 231 and at the other end to the clamping part 22.

[0082] Specifically, the second direction is Figure 5 The direction indicated by X in the middle.

[0083] Each of the connecting parts 23 is connected to at least one rotating part 21. For example, in a fixed unit 2, each of the connecting parts 23 may be connected to both of the rotating parts 21 or to one of the rotating parts 21, which is not limited here.

[0084] Each of the connecting parts 23 includes a slide rail 232, a slider 231, and a traction member 233. The slide rail 232 is fixedly connected to the first main board 11 of the container rack 1 to ensure its stability. Two slide rails 232 can be provided; two slide rails 232 can improve the stability of the slide rail 232 during sliding.

[0085] The slider 231 is slidably connected to the slide rail 232 and can slide along the slide rail 232. For example, the slider 231 is provided with a groove 2313, which cooperates with the slide rail 232, thus realizing the sliding of the slider 231 along the slide rail 232.

[0086] The slider 231 is provided with a rack 2311, which meshes with the gear 2113. Thus, when the rotating part 21 rotates, the gear 2113 also rotates with the rotating part 21. The rotating gear 2113 can drive the rack 2311 meshing with it and the slider 231 fixed to the rack 2311 to move. Thus, the slider 231 moves up and down along the slide rail 232 under the drive of the rotating part 21.

[0087] One end of the traction member 233 is connected to the slider 231, and the other end is connected to the clamping part 22. Thus, when the slider 231 moves up and down along the slide rail 232 under the influence of the rotating part 21, the moving slider 231 can drive the traction member 233 to move up and down, thereby causing the clamping part 22 connected to the traction member 233 to move closer to or further away from the container 3. For example, the traction member 233 can be a traction rope.

[0088] In each connecting part 23, there may be one, two, or more traction members 233, depending on the actual situation. In this embodiment, there are two traction members 233 in each connecting part 23 to ensure that the traction members 233 provide a stable traction effect on the clamping part 22.

[0089] In specific implementation, when container 3 enters container rack 1 through opening 14 and passes through third main board 13 and second main board 12 in sequence, in preparation to descend to first main board 11, the bottom of the descending container 3 will touch and press down on rotating plate 2112. When the free end 21122 of rotating plate 2112 is pressed by the bottom of container 3, it will rotate away from container 3. The rotating plate 2112 drives the rotating rod 2111 fixed to it to rotate together. The rotating rod 2111 drives the two gears 2113 fixed at both ends to rotate together. The rotating gears 2113 drive the rack 2311 meshing with it and the slider 231 fixed to the rack 2311 to move downward. The downward moving slider 231 drives the traction member 233 connected to it to move downward. The downward moving traction member 233 drives the clamping part 22 connected to it to move closer to container 3 until it clamps container 3.

[0090] When the container 3 is lifted so that the rotating part 21 is no longer squeezed, the rotating part 21 returns to its state before being squeezed under the action of the reaction force, that is, the rotating part 21 rotates in the opposite direction towards the container 3. Thus, the gear 2113 also rotates in the opposite direction along with the rotating part 21. The gear 2113 rotating in the opposite direction drives the rack 2311 meshing with it and the slider 231 fixed to the rack 2311 to move upward. The slider 231 moving upward drives the traction member 233 connected to it to move upward. The traction member 233 moving upward no longer applies traction to the clamping part 22 connected to it, so that the clamping part 22 moves away from the container 3 under the action of the reaction force and no longer clamps the container 3.

[0091] In this application, the connection part 23 makes the connection between the rotating part 21 and the clamping part 22 more stable, ensuring that the rotating part 21 can drive the slider 231 and the traction member 233 in the connection part 23 to move. The moving slider 231 and the traction member 233 can drive the clamping part 22 to move closer to or further away from the container 3, so as to automatically clamp or release the container 3.

[0092] In some embodiments, see Figure 8 and Figure 9 As shown, there are two clamping parts 22, which are spaced apart along the second direction. Each clamping part 22 is connected to the traction member 233 of the connecting part 23. Each clamping part 22 includes a clamping ring 221, and a clamping space for accommodating the container 3 is formed between the two clamping rings 221.

[0093] Specifically, the clamping ring 221 can be a semi-circular structure to better clamp the container 3.

[0094] Each clamping part 22 is connected to the traction member 233 of a connecting part 23. Thus, when the traction member 233 moves downward under the sliding motion, the downward-moving traction member 233 will drive the clamping part 22 connected to it to move closer to the container 3, thereby causing the clamping ring 221 of the clamping part 22 to also move closer to the container 3, until the clamping ring 221 clamps the container 3.

[0095] It is worth noting that for each fixed unit 2, since the two gears 2113 connected to the racks 2311 on the two sliders 231 in the two connecting parts 23 are connected to the two ends of the same rotating rod 2111, the moving positions of the two sliders 231 in the two connecting parts 23 are the same, so the moving positions of the traction members 233 in the two connecting parts 23 are also the same, and thus the moving positions of the two clamping parts 22 connected to the traction members 233 in the two connecting parts 23 are also the same. This ensures that the two clamping rings 221 in the two clamping parts 22 can be clamped from both sides at the same time, ensuring that the container 3 is clamped very firmly.

[0096] In some embodiments, see continue to see Figure 8 and Figure 9 As shown, each of the clamping parts 22 further includes a top plate 225, a push rod 222, and a connecting plate 223 fixed to the container frame 1. One end of the push rod 222 is connected to the clamping ring 221, and the other end of the push rod 222 passes through the top plate 225 and is connected to the connecting plate 223. The traction member 233 passes through the top plate 225 and is connected to the connecting plate 223.

[0097] Specifically, the top plate 225 is fixed to the fixing frame, which can ensure the stability of the entire clamping part 22. The traction member 233 passes through the top plate 225 and is connected to the connecting plate 223. The fixed top plate 225 can provide a limiting effect for the movement of the traction member 233, ensuring that the traction member 233 can move in a fixed direction.

[0098] After passing through the top plate 225, the traction member 233 connects to the connecting plate 223. Thus, when the traction member 233 moves downwards under the influence of the moving slider 231, it pulls the connecting plate 223 towards the container 3. This movement of the connecting plate 223 towards the container 3 causes the connected push rod 222 to also move towards the container 3. The push rod 222's movement towards the container 3 further causes the connected clamping ring 221 to move towards the container 3, thereby allowing the clamping ring 221 to clamp the container 3 (e.g., ...). Figure 8 (As shown).

[0099] Conversely, when the traction member 233 moves upward under the action of the slider 231, the traction member 233 no longer pulls on the connecting plate 223. Thus, the connecting plate 223 can return to its previous position under the action of the reaction force, that is, move away from the container 3. This, in turn, causes the push rod 222 and the clamping ring 221 to also move away from the container 3, thereby causing the clamping ring 221 to no longer clamp the container 3 and no longer fix the container 3 (e.g., ...). Figure 9 (As shown).

[0100] In some embodiments, see continue to see Figure 8 and Figure 9 As shown, the outer wall of the push rod 222 is fitted with a first elastic element 224, which is located between the top plate 225 and the connecting plate 223 and is connected to both the top plate 225 and the connecting plate 223.

[0101] Specifically, the first elastic element 224 may be made of a damped spring or an elastic pad. For example, the first elastic element 224 may be a return spring.

[0102] When the connecting plate 223 moves towards the container 3 under the pulling force of the traction member 233, the first elastic member 224 is compressed. When the traction member 233 moves upward under the sliding action, the traction member 233 is in a relaxed state and no longer exerts a pulling force on the connecting plate 223. At this time, the first elastic member 224 is no longer compressed, so the first elastic member 224 resets under the action of the spring's return capability and moves away from the container 3, thereby pushing the connecting plate 223 connected to it to move away from the container 3. The movement of the connecting plate 223 away from the container 3 will drive the push rod 222 connected to it to also move away from the container 3. The movement of the push rod 222 away from the container 3 will continue to drive the clamping ring 221 connected to it to also move away from the container 3, thereby causing the clamping ring 221 to leave the container 3 and no longer clamp the container 3.

[0103] Furthermore, each of the clamping portions 22 may also include at least one intermediate plate 227, the intermediate plate 227 being located between the connecting plate 223 and the top plate 225, one end of the push rod 222 being connected to the clamping ring 221, and the other end of the push rod 222 passing through the top plate 225 and each intermediate plate 227 in sequence before being connected to the connecting plate 223, and the traction member 233 passing through the top plate 225 and each intermediate plate 227 in sequence before being connected to the connecting plate 223.

[0104] Furthermore, there may be two first elastic elements 224. One first elastic element 224 is connected to the connecting plate 223 and the intermediate plate 227 near the connecting plate 223, and the other first elastic element 224 is connected to the top plate 225 and the intermediate plate 227 near the top plate 225. The function of the two first elastic elements 224 is to ensure that the connecting plate 223 has sufficient elastic force to push the connecting plate 223 to reset when it is not subjected to the pulling force of the traction member 233, so that the clamping ring 221 no longer clamps the container 3, and realizes the automatic release of the container 3.

[0105] In some embodiments, see continue to see Figure 8 and Figure 9 As shown, each of the clamping parts 22 also includes a guide wheel 226. The guide wheel 226 is located on the side of the top plate 225 away from the connecting plate 223. The guide wheel 226 is fixed to the container frame 1. The guide wheel 226 is in contact with the traction member 233 to guide the traction member 233. In this way, the guide wheel 226 can guide the traction member 233 and reduce the friction and resistance encountered by the traction member 233 during movement, thereby improving the efficiency of the entire device.

[0106] In some embodiments, see Figure 7 and Figure 10 As shown, each of the fixing units 2 further includes two locking units 25, which correspond one-to-one with the two connecting parts 23. Each locking unit 25 is located on the side of the corresponding connecting part 23 away from the opening 14.

[0107] Each of the locking units 25 includes:

[0108] Mounting plate 5254 is connected to the side of slide rail 232 opposite to slider 231;

[0109] The movable rod 252 is connected to the mounting plate 5254. One end passes through the mounting plate 5254 and can abut against or extend into the slider 231. It is configured to limit the slider 231.

[0110] Specifically, after the clamping ring 221 clamps the container 3, in order to ensure the clamping effect, the position of the clamping ring 221 needs to be fixed. In this way, the position of the clamping ring 221 can be fixed by fixing the position of the slider 231.

[0111] In this application, when it is necessary to fix the position of the slider 231, one end of the control moving rod 252 passes through the mounting plate 5254 and abuts against or extends into the slider 231 to limit and fix the slider 231, preventing the slider 231 from continuing to move along the slide rail 232, thereby fixing the position of the clamping ring 221 and ensuring that the clamping ring can continuously clamp the container 3.

[0112] When it is no longer necessary to clamp the container 3, the end of the control moving rod 252 separates from the slider 231, so the slider 231 is no longer limited by the moving rod 252. When the container 3 no longer presses against the rotating plate 2112, the rotating plate 2112 is released and rotates in the opposite direction, which drives the slider 231 to move upward. The upward movement of the slider 231 drives the traction member 233 to move upward. Thus, the traction member 233 no longer applies a pulling force to the connecting plate 223. Under the reset action of the first elastic member 224, the connecting plate 223 moves away from the container 3, thereby causing the clamping ring 221 to no longer clamp the container 3, allowing the container 3 to be freely removed.

[0113] In some embodiments, see Figure 7 and Figure 10 As shown, each of the locking units 25 further includes a fixing block 251, which is connected to the end of the moving rod 252 and located between the mounting plate 5254 and the slider 231. The slider 231 is provided with a plurality of mounting holes 2312. The fixing block 251 is configured to extend into at least one of the mounting holes 2312 under the push of the moving rod 252 to limit the slider 231, or to disengage from at least one of the mounting holes 2312.

[0114] Specifically, when it is necessary to fix the position of the slider 231, the control moving rod 252 moves towards the slider 231 until the fixing block 251 extends into at least one mounting hole 2312, so as to limit the slider 231.

[0115] When the position of the fixed slider 231 is not required, the control moving rod 252 moves away from the slider 231 until the fixed block 251 disengages from at least one mounting hole 2312, so that the slider 231 is no longer limited and can slide freely.

[0116] The slider 231 is provided with multiple mounting holes 2312, allowing the fixing block 251 to extend into different mounting holes 2312. Thus, regardless of the distance the slider 231 moves, the fixing block 251 of the locking unit 25 can always extend into the corresponding mounting hole 2312 to limit and fix the slider 231, improving the mixing efficiency of the samples in the container 3 and enhancing the overall practicality of the device.

[0117] In this way, containers 3 of different sizes can be placed in this device. The position of the locking unit 25 connected to the slider 231 can be flexibly adjusted according to the size of the container 3 placed in the container rack 1. This makes the distance that the slider 231 can move adjustable, so that the final distance that the clamping ring 221 moves can be adapted to the size of the container 3, so as to effectively clamp the container 3.

[0118] For example, when the size of the container 3 is large, the locking unit 25 is finally connected to the slider 231 at a position slightly below the slider 231. This way, the slider 231 can move a shorter distance, and the clamping ring 221 can also move a shorter distance, which is just right for the large container 3.

[0119] When the size of container 3 is small, the locking unit 25 is finally connected to the slider 231 at a position slightly above the slider 231. This allows the slider 231 to move a longer distance, and the clamping ring 221 to move a longer distance, which is just right for the small container 3.

[0120] In this application, not only can the locking unit 25 limit and fix the position of the slider 231, ensuring the fixed position of the slider 231 and the clamping ring 221, thus ensuring that the clamping ring 221 can continuously clamp the container 3, but also the connection position between the locking unit 25 and the slider 231 can be flexibly adjusted according to the different sizes of the container 3 placed inside the container 3. This allows adjustment of the moving distance of the clamping ring 221, so that the clamping ring 221 can effectively clamp and fix containers 3 of different sizes.

[0121] In some embodiments, a roller 256 is provided at one end of the fixed block 251 near the slider 231. When the slider 231 does not need to be limited, the roller 256 can roll relative to the slider 231 when the slider 231 slides along the slide rail 232. The setting of the roller 256 can reduce the friction between the fixed block 251 and the slider 231, so that the setting of the fixed block 251 will not cause significant interference or influence on the moving slider 231, and ensure that the slider 231 can slide normally.

[0122] When it is necessary to limit the slider 231, when the slider 231 slides to the specified position, the control moving rod 252 moves towards the slider 231 until the fixed block 251 and the roller 256 extend into at least one mounting hole 2312 to limit the slider 231.

[0123] In some embodiments, see continue to see Figure 7 and Figure 10 As shown, each of the locking units 25 further includes a limiting block 253 and a second elastic member 255. The limiting block 253 is connected to the end of the moving rod 252 and is located on the side of the mounting plate 5254 away from the slider 231. The second elastic member 255 is sleeved on the outer wall of the moving rod 252 and is connected to both the limiting block 253 and the mounting plate 5254.

[0124] Specifically, the limiting block 253 is connected to the end of the moving rod 252 and is located on the side of the mounting plate 5254 away from the slider 231. The limiting block 253 is used to limit the movement position of the moving rod 252. When the moving rod 252 is moved towards the slider 231 until the limiting block 253 contacts the mounting plate 5254, the mounting plate 5254 blocks the limiting block 253 from continuing to move, thereby blocking the moving rod 252 from continuing to move towards the slider 231, thus limiting the movement distance of the moving rod 252.

[0125] The movable rod 252 is threadedly connected to the mounting plate 5254. The movable rod 252 is controlled to move closer to or away from the slider 231 by rotating the movable rod 252.

[0126] The second elastic element 255 is sleeved on the outer wall of the moving rod 252. The second elastic element 255 is connected to both the limiting block 253 and the mounting plate 5254. The second elastic element 255 can be made of a damped spring or an elastic pad.

[0127] The second elastic element 255 provides a certain preload for the connection between the moving rod 252 and the mounting plate 5254, ensuring that the position of the moving rod 252 is effectively fixed, thereby ensuring that the moving rod 252 can lock the slider 231 in the required position and prevent the slider 231 from sliding accidentally.

[0128] In some embodiments, see Figure 11 As shown, the sample processing device further includes a mixing unit 4, which is connected to the bottom of the container rack 1. The top of the mixing unit 4 is provided with a vibration unit 6, which is used to vibrate the container rack 1 and the containers 3 on the container rack 1.

[0129] Specifically, the mixing unit 4 includes a housing and a control switch 41 disposed on the housing. A vibration unit 6 is provided on the top of the mixing unit 4. The vibration unit 6 is used to vibrate the container rack 1 and the container 3 on the container rack 1. Its vibration can efficiently promote the mixing of blood samples and anticoagulants inside the container 3, ensuring the uniformity and efficiency of mixing.

[0130] The top of the mixing unit 4 is also provided with a buffer unit 7, which can reduce the impact of vibration on the device, extend the service life of the mixing unit 4, and reduce maintenance costs.

[0131] The vibration unit 6 and the buffer unit 7 are provided with a mounting plate 5254 on top, and the container frame 1 is provided on top of the mounting plate 5254. Thus, the mounting plate 5254 provides installation space for the container frame 1, which facilitates the installation of the container frame 1.

[0132] The bottom of the easing unit is also provided with a support leg 42, which provides a stable support foundation for the mixing unit 4 and ensures the stability of the equipment during the mixing process.

[0133] In this application, a container 3 containing a sample is placed in a container rack 1. As the container 3 moves downward from the top of the container rack 1, its bottom contacts a rotating plate 2112. When the container 3 continues to press down on the rotating plate 2112, it applies a downward squeezing force, causing the rotating plate 2112 to rotate away from the container 3. The rotating plate 2112 drives the slider 231 in the connecting part 23 to move downward, and the downward-moving slider 231 causes the clamping part 22 to automatically clamp the container 3.

[0134] After the clamping part 22 clamps the container 3, the locking unit 25 can lock the position of the slider 231, thereby ensuring that the clamping part 22 can continuously clamp the container 3, ensuring that the container 3 remains stable during vibration, preventing the sample inside the container 3 from overflowing and becoming contaminated, and improving the accuracy of sample testing. In addition, since the connection position between the locking unit 25 and the slider 231 can be flexibly adjusted according to different sizes of the container 3, the practicality of the entire device is improved.

[0135] After fixing container 3, the vibration unit 6 is activated to vibrate container 3 and the sample inside container 3, so that the sample inside container 3 can be mixed evenly. After the sample mixing is completed, the locking unit 25 is moved away from the slider 231 so that the locking unit 25 no longer locks the slider 231. At this time, the slider 231 moves upward under the action of the resetting action of the rotating plate 2112, so that the traction member 233 connected to the slider 231 no longer provides a pulling force to the connecting plate 223. At this time, the connecting plate 223 is pushed away from the container 3 under the resetting action of the first elastic member 224, so that the clamping ring 221 no longer clamps the container 3. At this time, the container 3 is automatically released and can be taken out.

[0136] In this application, the container 3 can be automatically clamped, fixed, and released, making the fixing and releasing of the container 3 simple and quick, greatly reducing the difficulty of operation and alleviating the workload of technicians.
