Description

Technical Field

[0001] This application relates to the field of medical device technology, specifically to a test tube rack and a medical workbench. Background Technology

[0002] Test tube racks are essential auxiliary tools for medical testing, especially for crossmatching tests in hospital blood transfusion departments. They are widely used in clinical testing, blood typing, and biological sample processing. For example, in crossmatching operations, test tube racks are often used to classify and place blood samples from recipients and donors to facilitate clear sample differentiation and standardized operation.

[0003] When performing sample processing operations such as crossmatching, it is crucial to avoid mixing different types of samples to prevent misuse or omissions. Medical staff often use barcodes pre-attached to test tubes to distinguish and categorize different samples. When dealing with a large number of samples, medical staff may have to rely on memory and established default placement orders or areas on test tube racks based on daily habits to classify and place different samples. If negligence occurs, sample confusion may occur, posing serious safety hazards and severely affecting the accuracy and safety of the testing operation. Utility Model Content

[0004] In view of the above problems, this application provides a test tube rack and a medical workbench to solve the problems of difficulty in dividing and flexibly allocating areas in existing test tube racks.

[0005] According to one aspect of the embodiments of this application, a test tube rack is provided. The test tube rack includes: an upper plate, a support rod, a base, and at least two dividing strips; one end of the support rod is connected to the center of the base, and the other end is connected to the center of the upper plate, so as to support the upper plate above the base; one end of the dividing strip is rotatably connected to the center of the upper plate, and the other end of the dividing strip extends towards the edge of the upper plate; the upper surface of the upper plate has a plurality of first test tube holes for accommodating test tubes, and the dividing strip is used to rotate freely against the upper surface of the upper plate with the center of the upper plate as the axis of rotation, so as to divide the upper surface of the upper plate into multiple regions, and the plurality of first test tube holes are divided into multiple regions.

[0006] In one alternative approach, each dividing strip is provided with a first label plate at one end near the edge of the upper plate, the first label plate extending around a portion of the edge of the upper plate.

[0007] In one alternative approach, the movement trajectories of each first label plate as it rotates due to being driven by its corresponding divider do not overlap.

[0008] In one alternative embodiment, a lower plate is also included, the upper surface of which has a plurality of second test tube holes for accommodating test tubes, and a through hole is provided in the center of the lower plate, through which a support rod passes; at least one fixing strip is provided on the edge of the lower plate, one end of which is fixedly connected to the edge of the lower plate, and the other end is fixedly connected to the edge of the upper plate, so as to suspend the lower plate below the upper plate.

[0009] In one alternative configuration, the plurality of second test tube holes are vertically offset from the plurality of first test tube holes.

[0010] In one alternative embodiment, at least one second label plate is provided on the edge of the lower plate, the second label plate being provided along the edge of the lower plate in a direction away from the upper plate.

[0011] In one alternative embodiment, the base includes a stabilizing seat and a lower cover seat; the stabilizing seat is fixedly connected to one end of the support rod, and the lower cover seat is fitted onto the bottom of the stabilizing seat from bottom to top in the vertical direction; an annular guide rail is arranged around the center inside the lower cover seat, and a guide slide is provided at the bottom of the stabilizing seat. The guide slide is used to cooperate with the annular guide rail to guide the stabilizing seat to rotate along the annular guide rail inside the lower cover seat when the lower cover seat is fitted onto the bottom of the stabilizing seat.

[0012] In one alternative approach, the lower surface of the base is provided with multiple suction cups for fixing the base to the working surface.

[0013] In one alternative configuration, the first test tube orifice is arranged around the edge of the upper plate from the center of the upper plate, and is distributed in at least two rows on the upper surface of the upper plate.

[0014] According to another aspect of the embodiments of this application, a medical workbench is provided, including a work surface and a test tube rack as described above, the test tube rack being detachably mounted on the work surface.

[0015] By configuring an upper plate, support rod, base, and at least two rotatable dividing strips, the test tube rack provided in this embodiment allows the upper plate and at least two dividing strips to work together during use. The dividing strips rotate about the center of the upper plate, closely adhering to the upper surface of the upper plate. Multiple dividing strips work together to divide the surface of the upper plate into multiple independent areas. When a large number of test tubes need to be placed in a certain area, the size of the area can be flexibly adjusted by rotating the dividing strips to accommodate more test tubes. At the same time, since the dividing strips rotate closely to the surface of the upper plate, when test tubes are placed in the target area, the test tube openings will physically block the dividing strips from continuing to rotate. This allows the dividing strips to be precisely limited when adjusting the size of the area, achieving dynamic expansion of the test tube placement area while avoiding sample confusion. It also effectively eliminates the risk of mistakenly including test tubes from other areas in the expanded area due to over-rotation. There is no need to set up additional complex limiting mechanisms, which effectively improves operational flexibility and safety. Moreover, the structure is simple and compact, which helps to reduce equipment complexity and production costs.

For those skilled in the art, the specific meaning of the above terms in the embodiments of this application can be understood according to the specific circumstances.

[0027] With the development of modern medical testing technology, the requirements for the standardization and safety of sample management are increasing. Test tube racks are widely used in clinical testing, blood typing and biological sample processing. For example, in crossmatching, test tube racks are often used to classify and place blood samples from recipients and donors to meet the requirements of clear sample differentiation and standardized operation.

[0028] For medical testing, effective sample classification and management can improve the overall efficiency of testing operations and enhance the accuracy of sample verification. Precise zoning helps ensure the reliability of medical staff's operations in complex testing environments and improves the consistency and safety of tests such as crossmatching.

[0029] The inventors of this application have noted that commonly used test tube racks often employ fixed partitions or simple labeling for area division. However, when a certain area contains a large number of test tubes, the fixed-size area is often insufficient. Operators must repeatedly peel off the labels and manually reallocate areas for different samples. This method not only leads to low sample placement efficiency but also easily causes sample confusion due to repeated adjustments, posing serious safety hazards and severely affecting the accuracy and safety of testing operations.

[0030] To address the aforementioned technical problems, the inventors of this application have designed a test tube rack. The rack comprises an upper plate, a support rod, a base, and at least two dividing strips. One end of each dividing strip is rotatably connected to the center of the upper plate, while the other end extends towards the edge and rotates while remaining flush with the upper surface of the plate. This dynamically divides the upper plate surface into multiple areas. This design allows for flexible allocation of test tube placement areas based on the number of test tubes, effectively preventing sample confusion. Furthermore, the structure is streamlined and compact, eliminating the need for repeated label adjustments to dynamically expand the area, significantly improving the flexibility and safety of the testing operation.

[0031] Please refer to Figures 1 to 5 , Figure 1 This is a three-dimensional structural diagram of the test tube rack 1100 provided in the embodiments of this application. Figure 2 This is a three-dimensional structural diagram of the upper plate 100 and the lower plate 300 provided in an embodiment of this application. Figure 3 This is a three-dimensional structural diagram of the support rod 500 and the base 400 provided in the embodiments of this application. Figure 4 A bottom view of the upper plate 100 provided in an embodiment of this application. Figure 5 This is a top view of the upper plate 100 provided in an embodiment of this application. Figure 1-5 As shown, one embodiment of this application provides a test tube rack 1100, which includes: an upper plate 100, a support rod 500, a base 400, and at least two dividing strips 200; one end of the support rod 500 is connected to the center of the base 400, and the other end is connected to the center of the upper plate 100, so as to support the upper plate 100 above the base 400; one end of the dividing strip 200 is rotatably connected to the center of the upper plate 100, and the other end of the dividing strip 200 extends towards the edge of the upper plate 100; the upper surface of the upper plate 100 has a plurality of first test tube holes 110 for accommodating test tubes, and the dividing strip 200 is used to rotate freely against the upper surface of the upper plate 100 with the center of the upper plate 100 as the axis of rotation, so as to divide the upper surface of the upper plate 100 into multiple regions, and the plurality of first test tube holes 110 are divided into multiple regions.

[0032] The upper plate 100, support rod 500, base 400, and at least two dividing strips 200 are the core supporting and partitioning components of the test tube rack 1100. The support rod 500 is vertically oriented, its purpose being to securely support the upper plate 100 above the base 400 by connecting one end to the center of the base 400 and the other end to the center of the upper plate 100, forming the main frame of the test tube rack 1100. The upper surface of the upper plate 100 has multiple first test tube holes 110 for accommodating test tubes, providing placement positions for the test tubes. At least two dividing strips 200 are located above the upper plate 100, one end rotatably connected to the center of the upper plate 100, and the other end extending towards the edge of the upper plate 100, their purpose being to physically divide the upper surface of the upper plate 100 into multiple independent areas through rotation.

[0033] In actual use, please refer to Figure 5 and further refer to Figure 6 , Figure 6 A top view of the upper plate 100 when performing area allocation according to the embodiments of this application, as shown below. Figure 5 and Figure 6 As shown, the operator can adjust the separator 200 according to the required number of test tubes in different areas, making it rotate tightly against the upper surface of the upper plate 100 with the center of the plate 100 as the axis of rotation. When it is necessary to expand the capacity of a certain area, the corresponding separator 200 can be rotated to adjust the boundary of the area. During this movement, if test tubes are already placed in the target area, the test tube openings will physically block the separator 200 from continuing to rotate forward because the separator 200 rotates tightly against the surface of the upper plate 100. This prevents test tubes that were originally in another area from being accidentally included in the expansion area, thus making the area division and allocation more stable and reliable.

[0034] By incorporating an upper plate 100, a support rod 500, a base 400, and at least two rotatable dividing strips 200 into the test tube rack 1100, the test tube rack 1100 provided in this embodiment allows for flexible allocation of test tube placement areas during use, effectively preventing sample confusion. Furthermore, when a large number of test tubes are placed in a particular area, the size of the test tube placement area can be adjusted by rotating the dividing strips 200 to accommodate more test tubes. Since the dividing strips 200 rotate closely, once a test tube has been placed, it will be blocked by the test tube opening, preventing the risk of accidentally moving test tubes from other areas into the desired expanded area. This effectively improves operational flexibility and safety, and the simplified and compact structure helps reduce equipment complexity and production costs.

[0035] Please continue to refer to Figures 1 to 6 .like Figures 1 to 6 As shown, each dividing strip 200 has a first label plate 210 at one end near the edge of the upper plate 100, and the first label plate 210 extends around a portion of the edge of the upper plate 100.

[0036] The first label plate 210 is an identification and indication component of the test tube rack 1100. The purpose of the first label plate 210 is to provide a clear visual identification area so that operators can record or view relevant information about the test tubes in the corresponding section, such as recipient and donor information, and test tube type information. In terms of connection, each first label plate 210 is located at the end of the corresponding separator 200 near the edge of the upper plate 100, and extends around part of the edge of the upper plate 100. This ensures that the label plate moves synchronously with the separator 200 while maximizing the visible area of ​​the label.

[0037] In actual use, when the separator 200 is rotated to adjust the area size, the first label plate 210 moves synchronously with the separator 200 to the new area boundary position. The operator can intuitively see or update the area's identification information on the first label plate 210 without having to search for the label separately.

[0038] By providing a first label plate 210 extending around the edge of the upper plate 100 at the end of the separator 200, the first label plate 210 can dynamically identify the attributes of the current area when the test tube rack 1100 provided in this application is in use, as the separator 200 rotates. This achieves synchronous linkage between partition identification and area size adjustment, greatly facilitating the operator's quick verification and differentiation during dynamic expansion or contraction, further reducing the risk of sample confusion, and improving the convenience and accuracy of operation.

[0039] Please refer to Figures 6 to 9 , Figure 7 This is a top view of the upper plate 100 with the divider strip 200 stored in an embodiment of this application. Figure 8 This is a three-dimensional structural diagram of the upper plate 100 and the separator 200 provided in an embodiment of this application. Figure 9 A three-dimensional structural diagram of the upper plate 100 and the divider strip 200 when stored, provided in an embodiment of this application. According to some embodiments of this application, such as... Figures 6 to 9 As shown, the movement trajectories of each first label plate 210 do not overlap when it is rotated by its corresponding dividing strip 200.

[0040] The key design feature of the test tube rack 1100 is that the movement trajectories of the first label plates 210 do not overlap. This design aims to ensure that the first label plates 210 at the ends of the multiple separators 200 avoid each other spatially during rotation and adjustment, preventing physical collisions or jamming. Regarding the connection and movement process, since each first label plate 210 is driven to rotate by its corresponding separator 200, by rationally designing the length or initial angle of each separator 200, the annular spaces swept by the multiple first label plates 210 during rotation do not intersect.

[0041] In one embodiment of this application, such as Figures 5 to 7 As shown, when the operator rotates multiple separators 200 simultaneously or sequentially to redivide the area, each first label plate 210 moves within its own independent trajectory without interfering with each other, ensuring that the separators 200 can be smoothly rotated to the required position. When area division is not required, by rotating multiple separators 200 to overlap, the multiple first label plates 210 on the multiple separators 200 will not interfere with each other and can be smoothly stacked, reducing space occupation and allowing most of the first test tube holes 110 on the upper plate 100 to be exposed relatively completely.

[0042] In another embodiment of this application, such as Figure 8 and Figure 9 As shown, the movement trajectories can also be made non-overlapping by setting the first label plates 210 at different heights on the separator 200.

[0043] By ensuring that the movement trajectories of each first label plate 210 do not overlap when rotated by its corresponding separator 200, the test tube rack 1100 provided in this application embodiment will not experience the problem of label plates colliding with each other and causing rotation obstruction when multiple separators 200 are set for complex area division adjustments or when the separators 200 need to be stored. This ensures the smooth operation and long-term reliability of the test tube rack 1100's partition adjustment mechanism and improves the user experience.

[0044] Please refer to the above again. Figure 1 and Figure 2 According to some embodiments of this application, such as Figure 1 and Figure 2 As shown, it also includes a lower plate 300. The upper surface of the lower plate 300 has a plurality of second test tube holes 310 for accommodating test tubes. A through hole 320 is provided in the center of the lower plate 300, and the support rod 500 passes through the through hole 320. At least one fixing strip 330 is provided on the edge of the lower plate 300. One end of the fixing strip 330 is fixedly connected to the edge of the lower plate 300, and the other end is fixedly connected to the edge of the upper plate 100, so as to suspend the lower plate 300 below the upper plate 100.

[0045] The lower plate 300, the second test tube hole 310, the through hole 320, and the fixing strip 330 are extension components of the test tube rack 1100 for achieving double-layer classified storage. The lower plate 300 provides a second layer of test tube storage space, and its upper surface has multiple second test tube holes 310 for accommodating test tubes. The through hole 320 is located at the center of the lower plate 300, allowing the support rod 500 to pass through, achieving coaxial positioning between the lower plate 300 and the upper plate 100. The fixing strip 330 ensures stable suspension of the lower plate 300; one end is fixedly connected to the edge of the lower plate 300, and the other end is fixedly connected to the edge of the upper plate 100, thus suspending the lower plate 300 below the upper plate 100.

[0046] In actual use, the lower plate 300 is securely suspended directly below the upper plate 100 by the fixing strip 330. The operator can place the original specimen test tube into the second test tube hole 310 of the lower plate 300 and the operation test tube into the first test tube hole 110 of the upper plate 100. When the separator 200 of the upper plate 100 rotates to adjust the area, the lower plate 300 remains stationary, providing a stable bottom sample library for the operation of the upper plate 100.

[0047] By adding a lower plate 300 with a second test tube hole 310 and suspending it below the upper plate 100 using fixing strips 330, the test tube rack 1100 provided in this embodiment achieves a double-layer three-dimensional storage structure during use. The upper layer is used for blood matching operations, and the lower layer is used for raw specimen storage. Different types of test tubes are physically separated, completely avoiding the confusion between samples in the operation area and the storage area. At the same time, it makes full use of vertical space, multiplying the capacity of the test tube rack 1100 without increasing the floor space, and improving the space utilization rate of the operating table 1200.

[0048] Please continue to refer to Figure 1 and Figure 2 According to some embodiments of this application, such as Figure 1 and Figure 2 As shown, the multiple second test tube holes 310 are staggered from the multiple first test tube holes 110 in the vertical direction.

[0049] The vertically staggered arrangement of the second test tube hole 310 and the first test tube hole 110 is a structural layout design of the test tube rack 1100 to prevent interference. This arrangement aims to ensure that test tubes inserted into the first test tube hole 110 of the upper plate 100 and the test tubes inserted into the second test tube hole 310 of the lower plate 300 do not contact each other in vertical space. In terms of connection, the projections of the multiple second test tube holes 310 and the multiple first test tube holes 110 in the vertical direction do not completely coincide, resulting in a staggered arrangement.

[0050] In actual use, when both the upper plate 100 and the lower plate 300 are filled with test tubes, the bottom of the upper test tubes is suspended in the gap between the lower test tubes due to the staggered hole positions, preventing physical collision. Simultaneously, when the operator retrieves the lower test tubes, their line of sight and tools such as tweezers can be smoothly inserted through the gaps between the upper test tubes without obstruction.

[0051] By vertically offsetting the multiple second test tube holes 310 from the multiple first test tube holes 110, the test tube rack 1100 provided in this embodiment effectively avoids the risk of bottom contact or friction between the upper and lower test tubes in the double-layer test tube rack 1100 due to excessive length, ensuring smooth insertion and removal of test tubes. At the same time, the staggered layout provides operating space for the operator to retrieve the lower test tubes, avoids obstruction by the upper test tubes, and improves the efficiency of sample retrieval and operational visibility.

[0052] It is understood that in some advanced embodiments of this application, the first test tube hole 110 of the upper plate 100 and the second test tube hole 310 of the lower plate 300 can be staggered in a column-by-column manner to achieve the staggered arrangement of the first test tube hole 110 and the second test tube hole 310. For example, the area of ​​the upper plate 100 can be divided into multiple columns of areas that can be opened from the center to the edge by multiple straight lines. The first test tube hole 110 of the upper plate 100 is opened in the odd-numbered columns such as the 1st, 3rd, and 5th columns, forming a radial arrangement from the center to the edge of the upper plate 100. The second test tube hole 310 of the lower plate 300 is also set in the same way, but is opened in the even-numbered columns such as the 2nd, 4th, and 6th columns, so as to achieve the effect of the first test tube hole 110 and the second test tube hole 310 being staggered from each other in the vertical direction.

[0053] Meanwhile, to facilitate the handling of test tubes in the second test tube hole 310 of the lower plate 300 by medical staff, the distance between the upper plate 100 and the lower plate 300 can be adjusted according to the actual situation to improve ease of handling. For example, in some medical testing projects, due to the relatively long length of the test tubes used, if the distance between the upper plate 100 and the lower plate 300 is too short, collisions are likely to occur when handling the test tubes. In this case, operators often need to use tweezers or other auxiliary tools to grasp the inner test tube specimens, which not only easily leads to test tubes falling off and specimens spilling, but also makes the operation cumbersome and seriously affects the overall work efficiency, which is not as convenient as handling them by hand. Therefore, this application embodiment provides an improved structure that can appropriately increase the distance between the upper plate 100 and the lower plate 300 according to the actual length of the test tubes used and the work requirements. This solution effectively avoids the risk of collisions during the handling of long test tubes by expanding the operating space, allowing operators to directly handle the inner test tube specimens by hand, thereby improving the convenience, safety, and overall work efficiency of the operation.

[0054] Please continue to refer to Figure 1 and Figure 2 According to some embodiments of this application, such as Figure 1 and Figure 2 As shown, at least one second label plate 340 is provided on the edge of the lower plate 300, and the second label plate 340 extends along the edge of the lower plate 300 in a direction away from the upper plate 100.

[0055] The second label plate 340 is an identification component for the lower storage area of ​​the test tube rack 1100. Its purpose is to provide clear visual identification for each area of ​​the lower tray 300, allowing operators to record or view information about the original specimens in the lower tray and to trace their origin against the upper operating area. In terms of connection, the second label plate 340 is positioned at the edge of the lower tray 300 and extends downwards along the edge of the lower tray 300 away from the upper tray 100, thus avoiding obstruction by the upper test tubes and preventing obstruction or interference for medical personnel in retrieving or placing test tubes within the lower tray 300.

[0056] By setting a second label plate 340 extending away from the upper plate 100 at the edge of the lower plate 300, medical staff can also annotate or classify the test tubes in the lower plate 300 by labeling or other means. Furthermore, the downward-extending second label plate 340 is somewhat isolated from the area where the test tubes are placed in the lower plate 300, and the second label plate 340 is not easily contaminated by liquids that may drip when handling and placing test tubes, further ensuring the safety of high-risk operations such as cross-matching.

[0057] Please refer to Figure 1 and further refer to Figure 3 According to some embodiments of this application, such as Figure 1 and Figure 3 As shown, the base 400 includes a stabilizing seat 410 and a lower cover 420; the stabilizing seat 410 is fixedly connected to one end of the support rod 500, and the lower cover 420 is fitted onto the bottom of the stabilizing seat 410 from bottom to top in the vertical direction; an annular guide rail 421 is arranged around the center inside the lower cover 420, and a guide slide 411 is arranged at the bottom of the stabilizing seat 410. The guide slide 411 is used to cooperate with the annular guide rail 421 to guide the stabilizing seat 410 to rotate along the annular guide rail 421 inside the lower cover 420 when the lower cover 420 is fitted onto the bottom of the stabilizing seat 410.

[0058] The stabilizing base 410, lower support 420, circular guide rail, and guide slide 411 are the core mechanical components that enable the test tube rack 1100 base 400 to rotate. The stabilizing base 410 is designed to connect to and support the upper support rod 500; the lower support 420 provides a rotating base track. In terms of connection, the lower support 420 is fitted vertically from bottom to top onto the bottom of the stabilizing base 410, the circular guide rail is arranged around the center inside the lower support 420, and the guide slide 411 is located at the bottom of the stabilizing base 410. The purpose of the circular guide rail and guide slide 411 is to guide the rotation of the stabilizing base 410 when it is fitted.

[0059] In actual use, when the operator needs to change the orientation of the upper plate 100, a horizontal thrust is applied, and the guide slide 411 at the bottom of the stabilizer 410 slides in the circular guide rail of the lower plate 420, so that the stabilizer 410 rotates smoothly along the circular guide rail in the lower plate 420.

[0060] By splitting the base 400 into a stable base 410 and a lower base 420, and setting a circular guide rail and a guide slide 411 to cooperate, the test tube rack 1100 provided in this application embodiment can achieve 360-degree flexible rotation of the upper operating panel during use. At the same time, the cooperation between the guide rail and the guide slide 411 ensures the smoothness and concentricity of the rotation, reduces shaking during rotation, and improves the overall stability and user experience of the test tube rack 1100.

[0061] Please continue to refer to Figure 1 and Figure 3 According to some embodiments of this application, such as Figure 1 and Figure 3 As shown, the lower surface of the lower base 420 is provided with multiple suction cups 422, which are used to fix the base 400 to the working surface.

[0062] The suction cup 422 is a fixing device for the base 400 of the test tube rack 1100. Its purpose is to use the principle of atmospheric negative pressure to firmly attach the test tube rack 1100 to a smooth surface, such as the laboratory table 1200. In terms of connection, multiple suction cups 422 are set on the lower surface of the lower base 420, that is, the part that contacts the table 1200.

[0063] In actual use, when the test tube rack 1100 is placed on the tabletop 1200, pressing down on the support causes the suction cup 422 to deform under pressure, expelling internal air and creating a negative pressure that tightly adheres to the tabletop 1200. This provides a strong fixing force in the vertical direction, preventing the test tube rack 1100 from being accidentally lifted or knocked over. When it is necessary to rotate or move the test tube rack 1100 slightly, the operator applies a horizontal force. Due to the frictional characteristics of the bottom of the suction cup 422, the base 400 remains stationary, while the upper stabilizing seat 410 rotates relative to it, or the entire unit slides with minimal resistance.

[0064] By providing multiple suction cups 422 on the lower surface of the lower support 420, the test tube rack 1100 provided in this embodiment effectively solves the problem of ordinary test tube racks 1100 easily tipping over due to being scratched by sleeves or improper force when pulling out test tubes. The suction cup 422 structure ensures that the test tube rack 1100 is firmly attached to the tabletop 1200 during rapid operation, protecting the safety and biosafety of precious samples; at the same time, this structure is simple and reliable, and can achieve fixation and release without additional tools, making it very suitable for the daily high-frequency operation environment of medical laboratories.

[0065] Please refer to Figure 1 , Figure 2 and Figure 4 According to some embodiments of this application, such as Figure 1 , Figure 2 and Figure 4 As shown, the first test tube hole 110 is arranged around the edge of the upper plate 100 from the center of the upper plate 100, and is distributed in at least two rows on the upper surface of the upper plate 100.

[0066] The surrounding and multi-row distribution of the first test tube holes 110 constitutes the structural design of the capacity and layout of the test tube rack 1100. Its purpose is to maximize the number of test tubes that can be accommodated within the limited area of ​​the upper plate 100, and to achieve zoned management in conjunction with the rotation of the separator 200. In terms of connection, the first test tube holes 110 are arranged around the edge of the upper plate 100 from its center, and are distributed in at least two rows on the upper surface of the upper plate 100, forming a concentric circle or multi-ring radial array of holes.

[0067] In actual use, the operator inserts the test tubes into the first test tube holes 110, which are arranged in multiple rows. When the separator 200 is rotated, it spans multiple rows of test tubes, dividing the entire fan-shaped area from the center to the edge into independent units. Because the holes are arranged in a regular row, the separator 200 can easily pass through the gaps between the test tubes when rotated.

[0068] By configuring the first test tube holes 110 to be arranged in at least two rows, surrounding the center and extending to the edge, the test tube rack 1100 provided in this embodiment significantly increases the test tube loading capacity of a single tray during use, meeting the need for simultaneous processing of a large number of samples in crossmatch experiments. Simultaneously, the regular circular arrangement perfectly matches the rotatable separator 200, ensuring that regardless of the angle at which the separator 200 is rotated, a complete area containing multiple rows of test tubes can be effectively defined, improving the organization of experimental operations.

[0069] Please refer to Figure 10 , Figure 10 This is a schematic diagram illustrating an application scenario of the medical workbench 1000 provided in an embodiment of this application. According to another embodiment of this application, a medical workbench 1000 is provided, including a work surface 1200 and a test tube rack 1100 as described above, the test tube rack 1100 being detachably mounted on the work surface 1200.
