Description

Technical Field

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

[0002] A chemiluminescence analyzer is a medical device that analyzes the content of specific substances in biological samples by detecting chemiluminescent signals. Its principle is similar to that of fireflies, but it is applied to the precise detection of samples such as blood and urine. This technology can quickly identify disease biomarkers and is widely used in physical examinations and disease diagnosis.

[0003] A sample rack for a chemiluminescence analyzer is a storage device for sample tubes. The main functions of the sample rack are to provide stable support for the sample tubes, ensure sample safety, and facilitate sample loading and unloading. Existing sample tubes, for ease of operation, typically do not have individual caps, allowing external contaminants to easily enter and contaminate the samples. Therefore, to prevent sample contamination, a new sample rack for a chemiluminescence analyzer needs to be designed. Utility Model Content

[0004] The main purpose of this application is to propose a sample holder for a chemiluminescence analyzer, which aims to solve the problem that existing quality control systems usually do not have separate caps for ease of operation, allowing external debris to easily enter the sample tubes.

[0005] To achieve the above objectives, the sample holder for a chemiluminescence analyzer proposed in this application includes: a base, a placement rack on the base, a plurality of placement slots for placing sample tubes on the placement rack, an elastic clamping structure for holding the sample tubes in the placement slots, and an inverted U-shaped protective cover on the outside of the placement rack, the lower end of the protective cover being slidably connected to the base via a sliding structure.

[0006] Optionally, a protective plate is provided at the first end opening of the protective cover, and the protective plate is integrally formed with the protective cover. A baffle is provided at the second end opening of the protective cover. The protective plate and the baffle respectively cover the corresponding openings of the protective cover, and the lower end of the baffle is fixedly connected to the base.

[0007] Optionally, the sliding structure includes two guide grooves and two sliders. The two guide grooves are respectively opened on the side of the base, and the two sliders are respectively slidably disposed in the corresponding guide grooves. The two sliders are respectively fixedly installed on the side plate of the protective cover near the second end.

[0008] Optionally, the sliding structure further includes a guide channel and a guide rod. The guide channel is formed inside the base and is arranged parallel to the guide groove. The guide rod is slidably disposed in the guide channel, and one end of the guide rod extends out of the guide channel and is fixedly connected to the protective plate.

[0009] Optionally, a locking structure is provided between the protective cover and the baffle.

[0010] Optionally, the locking structure includes a mounting block, which is fixedly mounted on the top plate of the protective cover. A locking rod is provided through the mounting block, and the upper end of the locking rod is fixedly connected to an operating block. A locking hole is provided on the baffle corresponding to the locking rod, and the lower end of the locking rod passes through the top plate of the protective cover and is used to engage with the locking hole.

[0011] Optionally, a sliding block is fixedly installed on the side of the locking rod. The mounting block has a spirally distributed sliding groove inside corresponding to the sliding block. The sliding block extends into the corresponding sliding groove and slides in connection with it. A locking position is provided at the upper end of the sliding groove. An arc-shaped protrusion is provided at the connection between the locking position and the sliding groove to prevent the sliding block from entering the sliding groove on its own. A tension spring is fixedly connected between the operating block and the mounting block.

[0012] Optionally, the side of the operating block is provided with a concave arc-shaped handhold, and the handhold is provided with anti-slip texture.

[0013] Optionally, the elastic clamping structure includes a plurality of arc-shaped elastic sheets, which are evenly distributed in the placement groove, and the elastic sheets are fixedly connected to the inner wall of the placement groove.

[0014] Optionally, the plurality of placement slots on the placement rack are evenly distributed in a matrix.

[0015] The technical solution of this application is to set a base, a placement rack on the base, a placement rack with multiple placement slots for placing sample tubes, an elastic clamping structure for holding sample tubes in the placement slots, and an inverted U-shaped protective cover on the outside of the placement rack. The lower end of the protective cover is slidably connected to the base through a sliding structure. The operator aligns the sample tube containing the sample to be tested with the placement slot on the rack, and then places the sample tube into the slot. During placement, the sample tube compresses the elastic clamping structure within the slot, causing the structure to elastically deform. This deformation generates a counter-elastic force, which tightly adheres to the outer wall of the sample tube, thus stably clamping it within the slot and preventing it from shaking or tipping over during subsequent operations. Once all sample tubes are placed, the operator pushes the protective cover using a sliding mechanism. The protective cover, in an inverted U-shape, slides along the base, gradually covering the rack and the sample tubes on it, until it reaches the desired position, thus protecting the sample tubes. To remove the sample tube, the operator again slides the protective cover in the opposite direction using the sliding mechanism, and then removes the sample tube from the slot. The device features an inverted U-shaped protective cover that, when closed, covers the opening at the top of the sample tube, preventing dust, saliva, and other contaminants from the external environment from falling onto the sample tube and thus avoiding sample contamination. The sliding structure makes opening and closing the protective cover simple and convenient; operators can switch between protective states simply by pushing or pulling the cover, eliminating the need for complex disassembly and assembly steps, saving operation time and improving work efficiency. At the same time, the elastic clamping structure makes it easy to place and retrieve the sample tube without the need for additional fixing or unlocking operations. Attached Figure Description

[0025] A sample rack for a chemiluminescence analyzer is a storage device for sample tubes. The main functions of the sample rack are to provide stable support for the sample tubes, ensure sample safety, and facilitate sample handling. Existing sample tubes, for ease of operation, typically do not have individual caps, allowing external contaminants to easily enter and contaminate the samples. Therefore, to prevent sample contamination, a new sample rack for a chemiluminescence analyzer needs to be designed.

[0026] In view of this, this application proposes a sample holder for a chemiluminescence analyzer.

[0027] In the embodiments of this application, reference is made to Figures 1 to 4 The sample holder for the chemiluminescence analyzer mentioned above includes: a base 1, a placement rack 2 on the base 1, a plurality of placement slots 201 for placing sample tubes on the placement rack 2, an elastic clamping structure 3 for clamping the sample tubes in the placement slots 201, and an inverted U-shaped protective cover 4 on the outside of the placement rack 2. The lower end of the protective cover 4 is slidably connected to the base 1 through a sliding structure 5.

[0028] Specifically, the operator aligns the sample tube containing the sample to be tested with the placement slot 201 on the placement rack 2, and then places the sample tube into the placement slot 201. During placement, the sample tube will squeeze the elastic clamping structure 3 in the placement slot 201, causing the elastic clamping structure 3 to undergo elastic deformation. Under the action of elastic deformation, the elastic clamping structure 3 generates a reverse elastic force, which tightly adheres to the outer wall of the sample tube, thereby stably clamping the sample tube in the placement slot 201 and preventing the sample tube from shaking or tipping over in subsequent operations. After all sample tubes are placed, the operator pushes the protective cover 4 through the sliding structure 5. The protective cover 4, in the form of an inverted U-shape, slides along the base 1, gradually covering the placement rack 2 and the sample tubes on the placement rack 2, until the protective cover 4 slides to the appropriate position, thus protecting the sample tubes. When it is necessary to remove the sample tube, the operator slides the protective cover 4 in the opposite direction again through the sliding structure 5, and then removes the sample tube from the placement slot 201. The protective cover 4 is connected to the base 1 via a sliding structure 5, which provides guidance and support for the movement of the protective cover 4. The operator applies external force to the protective cover 4, enabling it to slide smoothly on the base 1 along the preset trajectory of the sliding structure 5. When the protective cover 4 slides to the position covering the placement rack 2, it utilizes its inverted U-shaped structure to form a physical barrier on the sample tubes on the placement rack 2 from above and both sides, preventing external dust, impurities and other contaminants from entering the sample tubes. It also prevents the sample tubes from falling off the placement rack 2 in case of accidental collisions.

[0029] In this embodiment, a protective plate 401 is provided at the first opening of the protective cover 4, and the protective plate 401 is integrally formed with the protective cover 4. A baffle 6 is provided at the second opening of the protective cover 4. The protective plate 401 and the baffle 6 respectively cover the corresponding openings of the protective cover 4, and the lower end of the baffle 6 is fixedly connected to the base 1. The protective cover 4 itself is an inverted U-shaped structure with two open ends. By integrally forming the protective plate 401 at the first opening, the opening at that end is directly closed. A baffle 6 is provided at the second opening and is fixedly connected to the base 1. When the protective cover 4 slides to contact the baffle 6, the baffle 6 fits tightly with the edge of the second opening of the protective cover 4, thereby closing the second opening of the protective cover 4. The protective plate 401, the protective cover 4, and the baffle 6 together constitute a complete closed protective space. Using the principle of physical isolation, it prevents external dust, impurities, etc. from entering the interior of the protective space, and also prevents the sample in the sample tube inside the protective space from leaking into the external environment due to accidental circumstances.

[0030] In other embodiments, the protective cover 4 and the protective plate 401 are preferably made of transparent materials, such as polycarbonate, acrylic, tempered glass, etc.; they have good light transmittance and protection, and allow operators to easily observe the position of the sample tube and the state of the sample through the protective cover 4 or the protective plate 401 while ensuring protection.

[0031] In this embodiment, the sliding structure 5 includes two guide grooves 501 and two sliders 502. The two guide grooves 501 are respectively formed on the side of the base 1, and the two sliders 502 are slidably disposed in the corresponding guide grooves 501. The two sliders 502 are respectively fixedly installed on the side plate of the protective cover 4 near the second end. When the protective cover 4 is closed, the protective cover 4 causes the sliders 502 to slide along the extension direction of the corresponding guide grooves 501. During the sliding process, the guide grooves 501 restrict and guide the movement trajectory of the sliders 502, ensuring that the sliders 502 can only move along the preset path of the guide grooves 501, thereby causing the protective cover 4 to slide smoothly and accurately towards the baffle 6 until the protective cover 4 contacts the baffle 6, completing the sealing protection. When it is necessary to open the protective cover 4, the protective cover 4 causes the slider 502 to slide in the opposite direction in the guide groove 501. The slider 502 moves away from the baffle 6 along the preset path of the guide groove 501, thereby driving the protective cover 4 to open smoothly until it slides to the appropriate position, so that the operator can easily take out the sample tube.

[0032] In this embodiment, the sliding structure 5 further includes a guide channel 503 and a guide rod 504. The guide channel 503 is opened inside the base 1 and is arranged parallel to the guide groove 501. The guide rod 504 is slidably arranged in the guide channel 503, and one end of the guide rod 504 extends out of the guide channel 503 and is fixedly connected to the protective plate 401. The cooperation between the guide groove 501 and the slider 502 enables the protective cover 4 to be guided on both sides in the horizontal direction, while the cooperation between the guide channel 503 and the guide rod 504 enables the protective cover 4 to be guided in the middle of the horizontal direction. The guide channel 503 and the guide groove 501 are set in parallel to ensure that the guiding directions of the three are consistent. This multi-directional guiding structure restricts and guides the sliding of the protective cover 4 from different positions, making the sliding trajectory of the protective cover 4 more precise. It can effectively resist the lateral or torsional forces that may occur during the sliding process, prevent the protective cover 4 from deviating or twisting, and ensure the smoothness and accuracy of the sliding. At the same time, the sliding of the guide rod 504 in the guide channel 503 can also play a certain traction and stabilizing role in the sliding of the protective cover 4, further enhancing the synchronicity and stability of the sliding of the protective cover 4.

[0033] In this embodiment, a locking structure 7 is provided between the protective cover 4 and the baffle 6. The locking structure 7 connects and fixes the protective cover 4 and the baffle 6 together, thereby restricting the sliding of the protective cover 4 and keeping it in a closed protective position. This prevents the protective cover 4 from sliding open on its own when not in operation, ensuring the stability of the protective state. The locking structure 7 includes a mounting block 710, which is fixedly mounted on the top plate of the protective cover 4. A locking rod 720 is inserted through the mounting block 710. The upper end of the locking rod 720 is fixedly connected to an operating block 740. A locking hole 730 is provided on the baffle 6 corresponding to the locking rod 720. The lower end of the locking rod 720 penetrates the top plate of the protective cover 4 and is used to engage with the locking hole 730. The locking rod 720 and the locking hole 730 are mechanically locked by a plug-in engagement. When the lower end of the locking lever 720 is inserted into the locking hole 730, a radial mechanical constraint is formed between the locking lever 720 and the locking hole 730, restricting the sliding of the protective cover 4 relative to the baffle 6 in the horizontal direction, thereby fixing the protective cover 4 in a closed position. This plug-in and pull-out structure is simple and reliable, and can quickly realize locking and unlocking operations.

[0034] In this embodiment, reference Figure 2 , Figure 3 A sliding block 721 is fixedly installed on the side of the locking lever 720. The mounting block 710 has a spirally distributed sliding groove 711 inside corresponding to the sliding block 721. The sliding block 721 extends into the corresponding sliding groove 711 and slides therewith. A locking position 712 is provided at the upper end of the sliding groove 711. An arc-shaped protrusion 713 is provided at the connection between the locking position 712 and the sliding groove 711 to prevent the sliding block 721 from entering the sliding groove 711 on its own. A tension spring 750 is fixedly connected between the operating block 740 and the mounting block 710. When locking is required, the operator slightly rotates the operating block 740, causing the sliding block 721 to disengage from the locking position 712 and enter the spiral sliding groove 711. At this time, the tension of the tension spring 750 drives the locking rod 720 to move downward, and the sliding block 721 slides downward along the spiral sliding groove 711. The lower end of the locking rod 720 is inserted into the locking hole 730, thus locking the protective cover 4. When unlocking is required, the operator rotates the operating block 740 in the opposite direction, causing the sliding block 721 to slide upward along the spiral sliding groove 711 until the sliding block 721 slides past the protrusion 713 and engages in the locking position 712. At this time, the lower end of the locking rod 720 disengages from the locking hole 730, thus unlocking the cover. The tension spring 750 is also stretched and stored, ensuring that the sliding block 721 remains against the locking position 712, preventing the sliding block 721 from disengaging from the locking position 712 on its own.

[0035] In this embodiment, the operating block 740 has a concave arc-shaped handle 741 on its side, and the handle 741 is provided with anti-slip texture. Because the handle 741 is concave arc-shaped, it can better fit the shape of the fingers, making it easier for the operator to apply force. At the same time, the anti-slip texture increases the friction between the fingers and the operating block 740, preventing the fingers from slipping during operation and ensuring that the operator can accurately and stably complete the rotation operation to achieve locking or unlocking.

[0036] In this embodiment, the elastic clamping structure 3 includes multiple arc-shaped elastic plates 301, which are evenly distributed within the placement groove 201 and fixedly connected to the inner wall of the placement groove 201. The multiple arc-shaped elastic plates 301 evenly distributed within the placement groove 201 can clamp the sample tube from multiple circumferential positions. Each elastic plate 301 generates an independent elastic restoring force when compressed by the sample tube. These elastic restoring forces form a uniform clamping force field circumferentially around the sample tube, ensuring a uniform distribution of clamping force on the sample tube. This avoids uneven force distribution on the sample tube due to single-point or few-point clamping, which could lead to tilting or damage. Simultaneously, multi-point clamping significantly improves the stability between the sample tube and the placement groove 201, enhancing the sample tube's resistance to shaking and tipping.

[0037] In this embodiment, the multiple placement slots 201 on the placement rack 2 are evenly distributed in a matrix. This uniform matrix distribution allows the multiple placement slots 201 to be arranged evenly and compactly on the placement rack 2, making full use of the planar space of the placement rack 2. Compared to irregular or excessively spaced distributions, more placement slots 201 can be set on the same size placement rack 2, increasing the sample carrying capacity of the sample rack, reducing the number of sample racks required, and saving laboratory space. The orderly matrix distribution also makes the placement, retrieval, and management of sample tubes more convenient. Operators can operate according to a fixed row and column order, reducing the likelihood of omissions or repetitive operations. Simultaneously, the sample tube numbers can correspond to the row and column coordinates of the matrix, facilitating the recording, tracing, and management of sample information, improving the accuracy and efficiency of sample management, and is particularly suitable for scenarios involving large-scale sample testing.

[0038] The technical solution of this application is to set a base, a placement rack on the base, a placement rack with multiple placement slots for placing sample tubes, an elastic clamping structure for holding sample tubes in the placement slots, and an inverted U-shaped protective cover on the outside of the placement rack. The lower end of the protective cover is slidably connected to the base through a sliding structure. The operator aligns the sample tube containing the sample to be tested with the placement slot on the rack, and then places the sample tube into the slot. During placement, the sample tube compresses the elastic clamping structure within the slot, causing the structure to elastically deform. This deformation generates a counter-elastic force, which tightly adheres to the outer wall of the sample tube, thus stably clamping it within the slot and preventing it from shaking or tipping over during subsequent operations. Once all sample tubes are placed, the operator pushes the protective cover using a sliding mechanism. The protective cover, in an inverted U-shape, slides along the base, gradually covering the rack and the sample tubes on it, until it reaches the desired position, thus protecting the sample tubes. To remove the sample tube, the operator again slides the protective cover in the opposite direction using the sliding mechanism, and then removes the sample tube from the slot. The device features an inverted U-shaped protective cover that, when closed, covers the opening at the top of the sample tube, preventing dust, saliva, and other contaminants from the external environment from falling onto the sample tube and thus avoiding sample contamination. The sliding structure makes opening and closing the protective cover simple and convenient; operators can switch between protective states simply by pushing or pulling the cover, eliminating the need for complex disassembly and assembly steps, saving operation time and improving work efficiency. At the same time, the elastic clamping structure makes it easy to place and retrieve the sample tube without the need for additional fixing or unlocking operations.

[0039] The above description is merely an optional embodiment of this application and does not limit the patent scope of this application. Any equivalent structural transformations made based on the inventive concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
