Description

Technical Field

[0001] This application relates to the field of pathological analysis technology, and more specifically, to a tissue dehydrator. Background Technology

[0002] In pathological diagnosis, tissue sample processing is a crucial initial step, and a tissue dehydrator is the core equipment in this process. Fresh tissue samples contain a large amount of water, making direct sectioning and staining impossible. A tissue dehydrator uses a gradient concentration of dehydrating agents (such as ethanol) to gradually replace the water in the tissue, laying the foundation for subsequent clearing and paraffin embedding steps. Only fully dehydrated tissue samples can be prepared into thin, uniform sections after paraffin embedding, providing pathologists with clear and accurate samples for microscopic observation of tissue structure and cell morphology—a key prerequisite for successful pathological diagnosis.

[0003] With the continuous development of the social economy and the steady increase in residents' income levels, the public's attention to health management has significantly improved, driving the demand for pathological diagnosis into a stage of rapid growth. Under the combined effect of multiple social development factors, the total amount of pathological specimens processed nationwide has more than doubled compared to ten years ago, and the average daily specimen processing volume of hospital pathology departments has increased significantly compared to the past, placing higher demands on the efficiency of departmental space utilization.

[0004] However, in older hospitals, due to structural limitations (such as the distribution of load-bearing walls and insufficient floor height), the cost of expanding departments is exorbitant (reaching 8,000-12,000 yuan / m2 in first-tier cities), and some hospitals even completely lose the possibility of space expansion. This forces the high demand for efficient departmental space utilization to translate into improved equipment utilization, making the improvement of equipment space utilization a key industry challenge. Furthermore, since cleaning and maintaining equipment after each workday consumes a significant amount of technicians' time, making equipment cleaning simpler and more convenient has become another major challenge for the industry. Utility Model Content

[0005] The purpose of this application is to provide a tissue dehydrator that not only improves the space utilization of the instrument, but also makes cleaning the instrument simpler and more convenient.

[0006] The embodiments of this application are implemented as follows:

The cylinder cover is fitted over the opening of the tissue processing cylinder. This tissue dehydrator not only improves the space utilization of the instrument but also makes cleaning the instrument simpler and more convenient.

[0008] As one possible implementation, a display is also included, which is used at least to display the working status of the instrument, and the display is disposed on the side of the worktable away from the operating position.

[0009] As one possible implementation, a support frame is provided on the workbench, and the display is detachably connected to the workbench via the support frame.

[0010] As one possible implementation, the interior of the machine body is also provided with a wax cylinder and a reagent bottle, the wax cylinder and the reagent bottle are respectively connected to the tissue processing cylinder, and the tissue processing cylinder and / or the wax cylinder are disposed on the reagent bottle.

[0011] As one possible implementation, a wax tank is also included inside the machine body, the wax tank being used to hold the wax cylinder. ， The wax box is provided with a door on the front side, and the wax cylinder is housed in the wax box through the door.

[0012] As one possible implementation, a waste wax collection box is provided below the wax box, and the wax box is provided with a wax discharge port, which is connected to the waste wax collection box so that the waste wax in the wax box flows into the waste wax collection box through the wax discharge port.

[0013] As one possible implementation, it also includes a reagent compartment disposed inside the body, with a pick-and-place port on the front side of the reagent compartment, through which the reagent bottle is placed in the reagent compartment.

[0014] In one possible implementation, the reagent bottles are multiple, and the multiple reagent bottles are arranged side by side along the dispensing port;

[0015] And / or, the number of the pick-up and put-out ports is multiple, and the multiple pick-up and put-out ports are arranged sequentially along the height direction of the machine body.

[0016] As one possible implementation, the machine body is also equipped with a filter, which is used to adsorb and filter the gas released from the reagent bottle and / or the wax tank.

[0017] As one possible implementation, the work surface is made of marble, and / or the side of the cylinder cover used to cover the tissue processing cylinder is coated with Teflon.

[0018] The beneficial effects of the embodiments of this application include:

[0019] The tissue dehydrator includes a main body with a tissue processing cylinder inside. The cylinder holds tissue samples for processing and is fitted with a cover. A workbench extends horizontally from the top of the main body and has an opening to expose the opening of the tissue processing cylinder. The cover closes to the opening of the cylinder. Compared to existing technologies, the workbench provided in this application features a horizontally extending planar design. This allows the user to use the workbench as a temporary work area to temporarily place sample baskets, dehydration boxes, or slide holders, improving space utilization. It eliminates the need for frequent movement between the tissue dehydrator and the storage rack, reducing unnecessary user movement, increasing work efficiency, and significantly lowering the probability of collisions between the user and the dehydrator or storage rack. This effectively enhances sample safety and greatly optimizes the convenience and reliability of pathological procedures. Furthermore, the planar design eliminates seams and uneven structures, so even if reagent residue occurs on the workbench, it can be easily removed by wiping. Attached Figure Description

Therefore, they should not be construed as limitations on this application. Furthermore, the terms "horizontal," "vertical," etc., do not indicate that the component must be absolutely horizontal or suspended, but can be slightly tilted. The terms "first," "second," and "third," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0028] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "set up," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0029] Please refer to the reference. Figures 1 to 4This application provides a tissue dehydrator 100, including a body 10. A tissue processing cylinder 11 is disposed inside the body 10. The tissue processing cylinder 11 is used to hold tissue samples for processing. The tissue processing cylinder 11 is equipped with a cylinder cover 111. A workbench 12 is formed on the top of the body 10, extending horizontally. An opening is provided on the workbench 12 to expose the opening of the tissue processing cylinder 11. The cylinder cover 111 covers the opening of the tissue processing cylinder 11. This tissue dehydrator 100 not only improves the space utilization of the instrument but also makes cleaning the instrument simpler and more convenient.

[0030] It should be noted that the tissue dehydrator 100 includes a body 10, which serves as the main frame. A tissue processing cylinder 11 is installed inside the body 10. A horizontally extending workbench 12 is formed on the top of the body 10, providing a planar space for users to temporarily place items (such as sample baskets, dehydration boxes, or slide holders). The tissue processing cylinder 11 is used to hold tissue samples for processing such as fixation, dehydration, clearing, and paraffin impregnation. An opening is provided on the workbench 12 to expose the opening of the tissue processing cylinder 11, facilitating sample placement, removal, operation, and observation. The tissue processing cylinder 11 is equipped with a cylinder cover 111, which can be closed to the opening of the cylinder to provide a seal, preventing splashing of processing liquid and evaporation of volatile gases into the external environment during tissue sample processing. It also prevents contaminants from the external environment from contaminating the tissue sample processing, ensuring operational safety.

[0031] Traditional tissue dehydrators typically have curved or sloping work surfaces with seams or uneven structures. This not only makes instruments prone to sliding or even tipping over, but also leaves residues that are difficult to remove. In contrast, the work surface 12 provided in this application adopts a horizontally extending planar design. This allows users to use the work surface 12 as a temporary work area to temporarily place instruments such as sample baskets, dehydration boxes, or slide holders, improving the space utilization of the instrument. It eliminates the need for frequent back-and-forth movement between the tissue dehydrator 100 and the storage rack, reducing unnecessary user movement, improving user efficiency, and significantly reducing the probability of collisions between the user and the tissue dehydrator 100 or the storage rack. This effectively enhances sample safety and greatly optimizes the convenience and reliability of pathological procedures. Furthermore, since the planar design eliminates seams and uneven structures, even if reagent residue occurs on the work surface 12, it can be easily removed by wiping.

[0032] As one possible implementation method, such as Figure 1 , Figure 3 and Figure 4As shown, the tissue dehydrator 100 also includes a display 20, which is used to display the working status of the instrument. The display 20 is located on the side of the worktable 12 away from the operating position.

[0033] It should be noted that the dehydrator 100 also includes a display 20 as a human-machine interface component. The display 20 has at least the function of displaying the instrument's operating status, such as real-time display of processing stages (e.g., fixation, dehydration, or wax impregnation), temperature, time progress, fault alarms, etc., helping operators to intuitively monitor the instrument's operation. In the layout design, the display 20 is placed on the side of the worktable 12 away from the operating position. Here, the "operating position" refers to the position where the user is performing operations such as sample handling and parameter setting on the worktable 12. In other words, there is a certain spatial distance between the location of the display 20 and the user's operating position.

[0034] Placing the monitor 20 on the side of the worktable 12 away from the operating position (such as the far end or side of the worktable 12) ensures that the user's line of sight is not obstructed when performing sample operations (such as contacting the tissue processing cylinder 11 through the opening), maintaining a clear view of the operating area. In this way, when processing samples, the user's gaze is primarily focused on the cylinder opening area of ​​the worktable 12; while when checking the instrument's operating status through the monitor 20, the user's gaze naturally moves to the distance or side. This layout conforms to the human eye's natural movement habits, reduces head turning, and improves operating comfort.

[0035] Meanwhile, placing the display 20 on the side of the workbench 12 away from the operating position (such as the far end or side of the workbench 12) can reduce the probability of users accidentally touching the screen of the display 20 when performing sample operations or cleaning the workbench 12. This is especially suitable for use scenarios where gloves are worn or frequent contact with liquids is required, and can effectively avoid incorrect parameter changes or instrument malfunctions caused by accidental touches. In addition, samples, processing fluids, or cleaning tools are easily come into contact near the operating position. Keeping the display 20 away from the operating position can also reduce damage to the display screen from sample contamination, liquid splashes, or mechanical impacts from cleaning tools, thus extending the service life of the equipment.

[0036] As one possible implementation method, such as Figures 1 to 4 As shown, a support frame 121 is provided on the workbench 12, and the display 20 is detachably connected to the workbench 12 via the support frame 121.

[0037] It should be noted that the dehydrator 100 also includes a support frame 121 on the worktable 12, which serves as a mounting carrier for the display 20, providing a stable mounting foundation and forming a detachable connection structure. For example, the display 20 and the support frame 121 can be quickly installed or removed using clips, bolts, magnets, etc., without tools, offering flexibility and adjustability. Through this detachable design, the display 20 can be adjusted in height or tilt angle (such as tilt or rotate) according to the user's height, posture, or viewing habits, ensuring that users of different body types can read information from a comfortable angle, reducing neck fatigue caused by prolonged upward or downward viewing.

[0038] When the monitor 20 malfunctions (such as screen damage or poor wiring contact), it can be directly removed from the support frame 121 for individual repair or replacement without disassembling the entire instrument body 10, reducing maintenance difficulty and cost, and shortening downtime. When moving the instrument, the monitor 20 can be temporarily removed and properly stored to avoid screen breakage or support frame 121 deformation due to collisions or vibrations, making it particularly suitable for scenarios requiring frequent mobile equipment movement (such as laboratory relocation or multi-site operations).

[0039] As one possible implementation method, such as Figure 4 As shown, the interior of the machine body 10 is also equipped with a wax cylinder 13 and a reagent bottle 14. The wax cylinder 13 and the reagent bottle 14 are respectively connected to the tissue processing cylinder 11, and the tissue processing cylinder 11 and / or the wax cylinder 13 are disposed on the reagent bottle 14.

[0040] It should be noted that the tissue dehydrator 100 also integrates a wax tank 13 and a reagent bottle 14 inside the machine body 10, forming a liquid processing system connected to the tissue processing tank 11. The wax tank 13 stores paraffin wax, primarily used in the paraffin impregnation stage of tissue sample processing, and delivers the paraffin solution to the tissue processing tank 11 via connecting pipes. The reagent bottle 14 stores treatment reagents such as fixatives, dehydrating agents (e.g., ethanol), and clearing agents (e.g., xylene), and injects the corresponding reagents into the tissue processing tank 11 sequentially according to the processing flow. The wax tank 13 and reagent bottle 14 are connected to the tissue processing tank 11 via pipes, valves, and other components, allowing for automated or manual control of reagent and paraffin solution delivery and recovery.

[0041] In the layout design, the tissue processing cylinder 11 and / or the wax cylinder 13 are positioned above the reagent bottle 14. For example, in some embodiments, the tissue processing cylinder 11, the wax cylinder 13, and the reagent bottle 14 can be arranged sequentially along the height direction of the machine body 10. Alternatively, in other embodiments, the tissue processing cylinder 11 and the wax cylinder 13 can be arranged side by side above the reagent bottle 14 along the height direction of the machine body 10. Regardless of the arrangement, the vertical space of the machine body 10 is fully utilized. Compared with the traditional layout where instruments are arranged sequentially along the horizontal direction, this saves the floor space of the tissue dehydrator 100, making it particularly suitable for laboratories with limited space.

[0042] As one possible implementation method, such as Figures 1 to 4 As shown, the tissue dehydrator 100 also includes a wax box 30 disposed inside the machine body 10. The wax box 30 is used to hold the wax cylinder 13. A door 31 is provided on the front side of the wax box 30, and the wax cylinder 13 is housed in the wax box 30 through the door 31.

[0043] It should be noted that the dehydrator 100 also includes a wax tank 30 inside the body 10, which serves as a dedicated space for the wax cylinder 13, forming an independent functional module. Specifically, the wax tank 30 can be a closed cavity inside the body 10, specifically designed to hold the wax cylinder 13, thereby providing a stable temperature environment for the wax cylinder 13 (e.g., maintaining the liquid wax state in conjunction with a heating module). A door 31 that can be opened is provided on the front side of the wax tank 30 (usually the direction facing the user). The door 31 can be opened and closed, for example, through a hinge, snap-fit, or slide rail, so that the wax cylinder 13 can be placed into or removed from the wax tank 30 through the door 31.

[0044] The wax tank 30 isolates the wax cylinder 13 from other components of the instrument body 10 (such as reagent bottles 14 and circuit modules), forming an independent, closed cavity. Heating elements (such as heating rods or temperature control modules) can be installed inside to precisely control the temperature of the wax cylinder 13 (e.g., maintaining the wax liquid in a molten state at 56℃~62℃). The closed structure reduces the influence of external ambient temperature on the wax cylinder 13, preventing the wax liquid from solidifying due to temperature fluctuations or evaporating due to overheating, thus ensuring the stability of the wax impregnation process. When the door 31 of the wax tank 30 is closed, the wax cylinder 13 inside the wax tank 30 is isolated from the external environment, preventing dust and debris from falling into the wax liquid, while also reducing the diffusion of wax vapor to other areas of the instrument body 10, keeping the instrument's interior clean, and preventing contamination of tissue samples or corrosion of other components.

[0045] As one possible implementation method, such as Figure 1 and Figure 2 As shown, a waste wax collection box 40 is provided below the wax box 30. The wax box 30 is provided with a wax discharge port, which is connected to the waste wax collection box 40 so that the waste wax in the wax box 30 flows into the waste wax collection box 40 through the wax discharge port.

[0046] It should be noted that the tissue dehydrator 100 also includes a waste wax collection box 40 below the wax tank 30, with a waste wax flow channel established through the wax discharge port. The waste wax collection box 40 is a separate container from the wax tank 30, used to collect waste wax overflowing from the wax cylinder 13 within the wax tank 30. The waste wax collection box 40 can be made of high-temperature resistant materials (such as stainless steel or heat-resistant plastic). The wax discharge port is located at the bottom or side of the wax tank 30, connected to the waste wax collection box 40 via a pipe or direct opening. This allows the waste wax to flow into the collection box from the discharge port by gravity or auxiliary suction, eliminating the need for manual cleaning of the bottom of the wax tank 30. This is particularly suitable for handling waste wax at high temperatures, preventing burns from direct contact with molten wax. In this way, waste wax can be discharged and stored in the waste wax collection box 40 in real time, without interrupting the operation of the tissue dehydrator 100, thus improving the continuity and efficiency of the tissue processing flow.

[0047] As one possible implementation method, such as Figures 1 to 4 As shown, the tissue dehydrator 100 also includes a reagent compartment 50 disposed inside the machine body 10. A pick-and-place port 51 is provided on the front side of the reagent compartment 50, and the reagent bottle 14 is placed in the reagent compartment 50 through the pick-and-place port 51.

[0048] It should be noted that the dehydrator 100 also includes a reagent compartment 50 inside the machine body 10, which serves as a dedicated storage module for reagent bottles 14, forming an independent reagent management system. Specifically, the reagent compartment 50 is an independent cavity inside the machine body 10, specifically designed for the centralized storage of reagent bottles 14 containing fixatives, dehydrating agents, clarifying agents, and other treatment reagents, thus providing a stable storage environment (such as light protection and temperature control) for the reagent bottles 14. An open access port 51 is located on the front side of the reagent compartment 50 (usually facing the user), allowing reagent bottles 14 to be easily inserted into or removed from the reagent compartment 50 through the access port 51.

[0049] As one possible implementation method, such as Figure 1 and Figure 2 As shown, there are multiple reagent bottles 14, which are arranged side by side along the pick-up and drop-off ports 51; and / or, there are multiple pick-up and drop-off ports 51, which are arranged sequentially along the height direction of the machine body 10.

[0050] It should be noted that, for example, in some embodiments, the reagent compartment 50 may be provided with only one retrieval port 51. In this case, multiple reagent bottles 14 in the reagent compartment 50 may be arranged side by side along the horizontal direction (i.e., the width direction of the retrieval port 51); or, in other embodiments, the reagent compartment 50 may be provided with multiple retrieval ports 51, and the multiple retrieval ports 51 may be arranged sequentially along the height direction of the body 10. The multiple reagent bottles 14 in the reagent compartment 50 may be classified and stored in independent storage spaces corresponding to different retrieval ports 51, thereby meeting the usage requirements of classified management.

[0051] As one possible implementation method, such as Figure 3 and Figure 4 As shown, the body 10 is also equipped with a filter 15 inside, which is used to adsorb and filter the gas released from the reagent bottle 14 and / or the wax tank 13.

[0052] It should be noted that the dehydrator 100 also integrates a filter 15 inside the machine body 10, which serves as a gas purification module. The core function of the filter 15 is to adsorb harmful gases released by the filter reagent bottle 14 and the wax tank 13 during use, thereby ensuring the health and safety of the operators.

[0053] As one possible implementation, the work surface 12 is made of marble, and / or the cylinder cover 111 has a Teflon coating on one side for covering the tissue processing cylinder 11.

[0054] It should be noted that marble was chosen as the material for the work surface 12 for several reasons. First, after precision grinding, marble has an extremely smooth surface, providing a stable placement reference for instrument components such as the display 20, as well as operating instruments such as sample baskets, dehydration boxes, or slide holders. Second, the dense and smooth surface of marble has a certain degree of resistance to common tissue processing reagents (such as ethanol and xylene), making it less susceptible to corrosion or staining. Even if reagents are accidentally splashed, they can be quickly wiped clean with a damp cloth, preventing liquid from seeping into the work surface and forming stubborn stains. Third, marble has superior scratch resistance. Traditional instrument plastic work surfaces usually require surface treatment with paint. When cleaning with a wax scraper, users are often hesitant to apply excessive force for fear of scratching off the paint and affecting the appearance. However, the marble work surface 12 eliminates this concern with scratches. Its higher surface hardness allows it to withstand more forceful cleaning operations, ensuring both the long-lasting aesthetics of the work surface and making cleaning more efficient and convenient.

[0055] A Teflon coating is provided on the side of the cylinder cover 111 used to cover the tissue processing cylinder 11. Firstly, the Teflon coating has extremely low surface roughness and is non-stick, preventing tissue samples, wax, or reagents from remaining on the sealing surface of the cylinder cover 111. For example, wax dripping during the wax impregnation process does not easily adhere to the coating after contact with it, and can be easily removed by gentle wiping, significantly reducing the difficulty and time of manual cleaning. Secondly, Teflon has extremely strong corrosion resistance to strong acids, strong alkalis, and organic solvents (such as formaldehyde and xylene), allowing it to withstand the erosion of tissue processing reagents for a long time, preventing rust or debris from forming on the metal substrate (such as stainless steel) of the cylinder cover 111, which could contaminate tissue samples or clog tubing. Thirdly, the Teflon coating can fill the micropores on the sealing surface of the cylinder cover 111, forming a more uniform contact interface and improving sealing reliability. Even if the coating wears slightly after long-term use, its self-lubricating properties can still maintain a good sealing effect, reducing the risk of evaporation of processing fluid or external contamination.

[0056] The above description is merely an optional embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.

[0057] It should also be noted that the various specific technical features described in the above embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this application will not describe the various possible combinations separately.
