Description

Technical Field

[0001] This invention relates to the field of medical testing technology, and more specifically, to a magnetically attached glass slide staining device. Background Technology

[0002] Slide staining is a widely used monitoring method in current clinical diagnosis and pathological research. Common applications include staining blood smears for diagnosing diseases such as anemia and leukemia, staining tissue sections for observing tissue lesions, and staining for certain special pathogens. This type of staining typically involves multiple steps, including smearing, drying, fixing, staining, elution, drying, reading, storage, and disposal, all of which require manual operation, resulting in difficulties in batch processing and low efficiency.

[0003] To support batch operations, existing technologies have developed racks with batch storage capabilities and support for batch staining. For example, the blood smear staining rack disclosed in prior art (CN205003008U) includes a support frame, several partitions, and a waste liquid tank, a staining platform, and a placement platform arranged sequentially from bottom to top on the support frame. The staining platform includes several first sliding grooves arranged on the support frame; the placement platform includes several second sliding grooves arranged sequentially from top to bottom on the support frame. The partitions are slidably mounted on the support frame via the first or second sliding grooves, and the partitions are perforated plates. This type of rack only supports the function of supporting slides through the partitions, supports batch placement of slides, and prevents slides from sliding off the partitions through protrusions, but it does not have the function of fixing slides. Furthermore, it only supports batch use in the staining and storage steps. During drying, fixing, and slide reading processes, slides still need to be manually removed from the partitions. The disassembly process is cumbersome and prone to cuts from sharp slides, posing a significant risk of occupational exposure and infection. Moreover, the operation still consumes a large amount of manpower and space.

[0004] Therefore, there is an urgent need for a slide staining device that is easy to operate, highly efficient, and precise. Summary of the Invention

[0005] The present invention aims to provide a magnetically attached glass slide staining device to solve the problems of existing supports having limited functionality, inconvenience of use, and limited efficiency improvement.

[0006] This invention is achieved using the following technical solution: In one aspect, the present invention provides a magnetically attached glass slide staining device, including a single carrier for fixing and supporting a single glass slide; The single carrier includes a frame and a glass slide receiving area surrounding the frame. The frame is configured with the edges of the upper and lower sides inclined inward to achieve primary flow guidance of the liquid, directing the liquid to flow into the glass slide receiving area surrounding the frame. The frame is also provided with a flow guide groove to achieve secondary flow guidance of the liquid, directing the liquid to flow into the glass slide receiving area surrounding the frame, while accelerating the liquid flow. When stacked, the fluid can be guided from all sides into the interior to contact the glass slide, thereby promoting contact between the smear and the liquid, and achieving sufficient staining and elution of the glass slide.

[0007] At least one side of the slide-receiving area surrounded by the frame is provided with a multi-functional area, which is fixedly connected to or integrally formed with the frame; the multi-functional area is provided with a through hole facing the same direction as the slide-receiving area, and is also provided with a retractable slide fastener. Preferably, the slide fastener is, for example, a magnetic spring clip.

[0008] The advantage of this design is that it allows the extension and retraction of the spring latch to be controlled by an external magnetic field, thereby assisting in the loading of the glass slides; it can also retract based on the pushing action of the glass slides. When batch tilting is required, the external magnetic field can be used to control several stacked glass slides at once, enabling batch control, batch dropping, and rapid batch tilting, saving time while ensuring safety.

[0009] The advantage of the through hole is that when the carrier is immersed in the liquid, the liquid can enter the slide area through the through hole to allow for a full reaction; and when the carrier is removed from the liquid, the liquid can flow out of the slide area quickly through the through hole, preventing liquid accumulation.

[0010] According to a preferred embodiment, a connector for connecting another single-unit carrier is provided on one top surface of the frame of the single-unit carrier; alternatively, connectors for connecting another single-unit carrier are symmetrically provided on two opposite top surfaces of the single-unit carrier. Preferably, a magnet is provided on the connector. The connector, on the other hand, is used to determine the distance between two stacked carriers to ensure sufficient fluid inflow channels when stacked, the fluid being a liquid (dyeing solution or elution solution) and a gas (drying gas flow). Preferably, at least two or four connectors are symmetrically arranged; three or more may also be used.

[0011] The advantages of the connector design are: On the one hand, the design of the connectors enables the collective and unified movement and processing of individual carriers, which facilitates batch staining, drying, elution, and disposal steps, greatly saving the time required for these steps; at the same time, it supports stacked storage, does not take up space, and will not cause cross-contamination; after the slides are destroyed, the carriers can fix new slides for reuse, saving resources, and the magnetic connectors are not easily damaged. On the other hand, the connectors, through the design of magnets, help to quickly connect two or more single carriers, and quickly and accurately align and stack them, thereby reducing the time required for manual stacking and alignment; at the same time, the stacked slides will not come into contact with each other during batch processing, eliminating the risk of scratching the samples. In addition, the design of the connectors helps to detach the individual carriers from the stacked state, and the individual carriers can be directly picked up when microscopic observation is needed, which is simple and convenient; it will not contaminate the slides, and due to the surrounding frame fixing method of this application, it is not easy to scratch the observer's fingers; and the magnetic design of this application allows for more flexible assembly, and can even be attached to iron wall panels for display.

[0012] In summary, the magnetic slide staining device of this application is flexible in use, meets the needs of both overall batch operations and single observations, has good safety, and can also avoid contamination.

[0013] Another aspect of the present invention provides a staining reactor adapted to a magnetic slide staining apparatus as described above, the staining reactor being divided into an upper part and a lower part opposite to the upper part; The lower part of the staining reactor is designated as the reaction zone, and the upper part is designated as the mixing zone. The reaction zone has several radially arranged reaction chambers with open tops around a central axis. Each reaction chamber is capable of accommodating the magnetically attached slide staining device described above. The mixing zone is equipped with a telescopic rotating arm for moving the magnetically attached slide staining device. The telescopic rotating arm has a connecting rod for connecting the slide and a rotating telescopic shaft for supporting and carrying the connecting rod. The central axis of the rotating telescopic shaft is coaxial with the central axis around which the reaction chambers are located.

[0014] Preferably, one end of the rotating telescopic shaft is connected to the lower part of the staining reactor, the other end away from the lower part of the staining reactor is connected to the connecting rod, and the other end of the connecting rod away from the rotating telescopic shaft is connected to a magnetic slide staining device as described above.

[0015] Preferably, one end of the rotary telescopic shaft connected to the lower part of the dyeing reactor is also connected to a drive motor, which drives the rotary telescopic shaft to rotate.

[0016] Preferably, the magnetic slide staining device described above is connected to a connecting rod via a carrier frame. Preferably, the carrier frame is a mesh frame, designed to match and support the shape of the magnetic slide staining device described above, with side openings for inserting the device. Preferably, the connection between the carrier frame and the connecting rod is detachable, for example, a snap-fit ​​or fastening connection. With the above configuration, when the rotating telescopic shaft rotates and moves vertically, it drives the carrier and slides to switch between different reaction chambers, thereby achieving batch operation.

[0017] Preferably, the reaction chamber includes a smear drying chamber, a fixation chamber, a staining chamber, a buffer chamber, a rinsing chamber, a slide drying chamber, a temporary storage chamber, and a slide rewinding chamber arranged in sequence.

[0018] After manual batch preparation of slides, they are placed in a slide drying chamber with warm air circulation to dry the slides in batches. The dried slides are then transferred to a fixing chamber containing a fixative solution, where the slides on the carriers are fixed. After fixing, the slides are transferred to a staining chamber containing a staining solution, where they are stained. After staining, the slides are transferred to a buffer chamber containing a buffer solution for pH equilibration. After equilibration, they are transferred to a rinsing chamber containing an elution solution for elution. After elution, the slides are transferred to a drying chamber with warm air circulation for drying. They are then transferred to a temporary storage chamber for storage. Each slide is reviewed individually. After review, the stacked slide carriers are inverted and tilted on a carrier rack and moved to a rewinding chamber. An external magnetic field is applied, causing the slide holders on each individual carrier to contract, allowing the slides to fall into the rewinding chamber in batches by gravity, thus achieving batch disposal.

[0019] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. Batch operation, saving time and effort: The slides are fixed by a single carrier, which drives the batch stacking of slides. With the help of the structural design of the single carrier, the steps of batch fixing, staining, buffering, rinsing, drying and destruction can be realized, realizing batch processing of the whole process. It is not easy to contaminate and overcomes the problem of cumbersome operation in the industry. 2. Flexible, safe, and pollution-free: It not only supports rapid alignment and stacking of individual carriers, but also enables rapid disassembly from the stacked state to the single state, thus enabling slide testing with the carrier. Testers only need to pick up the carrier frame, which is less likely to cause injury or contaminate the slides, and also avoids occupational exposure for testers (avoiding infection with highly infectious diseases such as HIV and syphilis); at the same time, there is no limit to the number of stacks, and those skilled in the art can stack arbitrarily and flexibly according to the actual number of samples.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Example 1 A magnetic slide staining device includes a single carrier, such as Figure 1 and Figure 2As shown, this is a carrier used to fix and support a single glass slide. The single carrier includes a frame 1 and a glass slide receiving area 2 surrounded by the frame. The frame 1 is configured with its upper and lower edges inclined inward to achieve primary flow guidance of the liquid, directing the liquid flow to the glass slide receiving area 2 surrounded by the frame. The frame 1 is also provided with a flow channel 3 to achieve secondary flow guidance of the liquid, directing the liquid flow to the glass slide receiving area 2 surrounded by the frame, while accelerating the flow of the liquid into the glass slide receiving area 2. Multiple single carriers can also be stacked on top of each other. When stacked, the frame 1 and the flow channel 3 can guide fluid from all sides into the internal glass slide receiving area 2, contacting the glass slide, thereby promoting full contact between the smear and the dye, eluent, drying warm air, etc., to achieve sufficient staining, elution, or drying of the glass slide.

[0024] A multifunctional area 4 is provided on at least one side of the slide receiving area 2 surrounded by the frame 1. The multifunctional area 4 is fixedly connected to or integrally formed with the frame 1. The multifunctional area 4 is provided with a through hole 41 facing the same direction as the slide receiving area 2, and also provides a retractable slide fixing member 42. Preferably, the multifunctional area 4 is provided with a guide groove 423 for receiving the slide fixing member 42. The slide fixing member 42 extends and retracts within the guide groove 423 based on the limiting and guiding of the guide groove 423. The direction of the guide groove 423 is parallel to at least one side of the slide placed in the slide receiving area 2. Preferably, the frame 1 is rectangular or square. Preferably, the material of the single carrier is plastic or alloy, for example, it can be made of PLA (polylactic acid) environmentally friendly material (biodegradable). Preferably, the slide fixing member 42 is, for example, a magnetic spring buckle. For example, such as Figure 5 As shown, the magnetic spring clip includes a spring plate 421 and a magnetic tongue 422 disposed in a guide groove 423. One end of the spring plate 421 is connected to the inner wall of the guide groove 423, and the other end is connected to the magnetic tongue 422. When an external magnetic field is applied, the magnetic field drives the magnetic tongue 422 to squeeze the spring plate 421, thereby retracting the magnetic tongue 422 and releasing the glass slide. When the magnetic field is removed, the spring plate 421 pushes the magnetic tongue 422 out based on the elastic potential energy stored during the compression, and then the magnetic tongue 422 abuts against the edge of the glass slide to fix the glass slide.

[0025] The advantage of this design is that the magnetic spring clips can be controlled by an external magnetic field to extend and retract, thus assisting in loading the glass slides; they can also retract based on the pushing action of the glass slides. When batch unloading is required, the external magnetic field controls the retraction of the magnetic spring clips, thereby releasing the glass slides from the individual carrier. This allows for the rapid unloading of several stacked glass slides at once, saving time while ensuring safety.

[0026] The advantage of the through hole 41 is that when the single carrier is immersed in the liquid, the liquid can enter the slide area through the through hole to facilitate a full reaction; and when the carrier is removed from the liquid, the liquid can quickly flow out of the slide area through the through hole, preventing liquid accumulation. Preferably, the through hole 41 can be square, circular, or grid-shaped.

[0027] According to a preferred embodiment, a connector 5 for connecting another single-unit carrier is provided on one top surface of the single-unit carrier; or, connectors 5 for connecting another single-unit carrier are symmetrically provided on two opposite top surfaces of the single-unit carrier. Preferably, a magnet is provided on the connector 5. One end of the connector 5 is connected to the top surface of the frame, and the other end is connected to the magnet for connecting to another single-unit carrier. Preferably, the connection can be a fixed connection such as adhesive bonding or embedded connection, or other connection methods commonly used in the art. Preferably, the connector 5 can also be made entirely of magnets. The connector, on the other hand, is used to determine the distance between the two stacked carriers so as to provide sufficient fluid entry channels when stacked, the fluid being a liquid (dyeing solution or elution solution) and a gas (drying gas flow). Preferably, at least two or four connectors 5 are symmetrically arranged; three or more may also be used. Preferably, the overall height of the connector 5 is preferably 1.5 mm.

[0028] The advantages of the connector design are: On the one hand, the design of the connectors enables the collective and unified movement and processing of individual carriers, which facilitates batch staining, drying, elution, and disposal steps, greatly saving the time required for these steps; at the same time, it supports stacked storage, does not take up space, and will not cause cross-contamination; after the slides are destroyed, the individual carriers can fix new slides for reuse, saving resources, and the magnetic connectors are not easily damaged. On the other hand, the connectors, through their magnetic design, facilitate the rapid connection of two or more individual vehicles, enabling quick and accurate alignment and stacking, thereby reducing the time required for manual stacking and alignment; for example... Figure 3 The diagram shows a stacked configuration of individual vehicles.

[0029] In addition, the design of the connectors helps to detach the individual carriers from the stacked state, and the individual carriers can be directly picked up when microscopic observation is needed, which is simple and convenient; it will not contaminate the slides, and due to the surrounding frame fixing method of this application, it is not easy to scratch the observer's fingers; and the magnetic design of this application allows for more flexible assembly, and can even be attached to iron wall panels for display.

[0030] In summary, the magnetic slide staining device of this application is flexible in use, meets the needs of both overall batch operations and single observations, has good safety, and can also avoid contamination.

[0031] Example 2 Another aspect of the present invention provides a staining reactor adapted to a magnetic slide staining apparatus as described above, such as... Figure 4 As shown, the staining reactor is divided into an upper part 6 and a lower part 7 opposite to the upper part 6. The lower part 7 of the staining reactor is set as the reaction zone, and the upper part 6 of the staining reactor is set as the mixing zone. The reaction zone has a plurality of reaction chambers with open tops arranged radially around a central axis. The reaction chambers are capable of accommodating a magnetic slide staining device as described above. The mixing zone is equipped with a telescopic rotating arm for moving the magnetic slide staining device as described above. The telescopic rotating arm is equipped with a connecting rod 10 for connecting the slide and a rotating telescopic shaft 9 for supporting and carrying the connecting rod. The central axis of the rotating telescopic shaft 9 is coaxial with the central axis around which the reaction chambers are located.

[0032] Preferably, one end of the rotating telescopic shaft 9 is connected to the lower part 7 of the staining reactor, and the other end away from the lower part 7 of the staining reactor is connected to the connecting rod 10. The other end of the connecting rod 10 away from the rotating telescopic shaft 9 is connected to a magnetic slide staining device as described above.

[0033] Preferably, one end of the rotary telescopic shaft 9 connected to the lower part 7 of the dyeing reactor is also connected to a drive motor, which drives the rotary telescopic shaft to rotate. Preferably, the drive motor can be located in the lower part 7 of the dyeing reactor, in the middle part surrounding the reaction chambers.

[0034] Preferably, the magnetic slide staining apparatus as described above is connected to the connecting rod via a carrier frame 11. Preferably, the carrier frame 11 is a mesh frame, matching the shape of the magnetic slide staining apparatus as described in Example 1, thus capable of supporting the staining apparatus. The carrier frame 11 has an opening on its side for inserting the magnetic slide staining apparatus as described in Example 1. Preferably, the connection between the carrier frame 11 and the connecting rod 10 is detachable, for example, by a snap-fit ​​or fastening connection, to facilitate replacement of the carrier frame 11 or batch movement of the magnetic slide staining apparatus as described in Example 1. With the above configuration, when the rotating telescopic shaft 9 rotates and moves up and down, it drives the carrier and slides to switch between different reaction chambers, thereby achieving batch operation. Preferably, the carrier frame 11 is made of a material that can be magnetically attracted, such as iron.

[0035] Preferably, the reaction chamber includes a smear drying chamber 81, a fixation chamber 82, a staining chamber 83, a buffer chamber 84, a rinsing chamber 85, a slide drying chamber 86, a temporary storage chamber 87, and a slide rewinding chamber 88 arranged in sequence.

[0036] After manual batch preparation of glass slides, they are placed in a preparation drying chamber 81. The preparation drying chamber 81 is equipped with a warm air outlet, connected to an external or internal heater, to blow warm air into the chamber for batch drying. The dried slides are then transferred to a fixing chamber 82, which contains a fixative solution. The slides on the carrier are fixed under the action of the fixative solution. The fixed slides are then transferred to a staining chamber 83, which contains a staining solution. The staining solution is used to stain the slides. After staining, the slides are transferred to a buffer chamber 84, which contains a buffer solution for pH equilibration. After equilibration, the slides are transferred to a rinsing chamber 85, which contains a rinsing solution. An eluent is provided for eluting the slides. After elution, the slides are transferred to a drying chamber 86, which is equipped with a warm air outlet and can be connected to an external or internal heater to blow warm air into the drying chamber 86 to dry the slides. The dried slides are then transferred to a temporary storage chamber 87 for storage, awaiting individual slide reading. After reading, the stacked slide carriers are inverted and tilted on a carrier rack and moved to a rewinding chamber 88. The rewinding chamber 88 has an electromagnet on one or the other side of the multi-functional area corresponding to each individual carrier. When energized, it generates a strong magnetic field; when de-energized, it loses its magnetism. This allows the application of an external magnetic field to cause the slide holders 42 on each individual carrier to contract, causing the slides to fall in batches into the rewinding chamber 88 under their own weight, achieving batch disposal. Preferably, as follows... Figure 6 As shown, the film rewinding chamber 88 is equipped with an electromagnet 881 and a waste slide receiving space 882 located below the electromagnet 881 for accommodating waste slides. Preferably, the electromagnet 881 is electrically connected to an external power source. Preferably, the circular electromagnet 881 is rotatably connected to the film rewinding chamber 88 around its central axis. In use, the electromagnet 881 is energized to generate a first-order magnetic force, attracting the carrier frame 11 and the stacked carriers, and rotating the carrier frame 11. When the rotation is about 100°, the power source is controlled to increase the magnetic force of the electromagnet 881, causing the slide fixing member 42 on the carrier to retract, releasing the slides. The slides then fall from the opening end of the carrier frame 11 into the waste slide receiving space 882 under gravity, realizing batch film rewinding.

[0037] Preferably, the fixing chamber 82, staining chamber 83, buffer chamber 84, and rinsing chamber 85 are provided with leakage holes, and switches for controlling the opening and closing of the leakage holes are provided to facilitate the replacement of various liquids. The number and size of the reaction chambers can be set by those skilled in the art according to their needs, and do not necessarily need to be the uniform distribution state of this application.

[0038] Traditional rinsing and staining methods require single-slide operation to avoid scratching the samples with each slide; the staining device of this application can not only achieve batch operation, but also the immersion method of this application is more economical in terms of reagents compared with the rinsing method.

[0039] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
