Description

Technical Field

[0001] This invention relates to the field of laboratory equipment for microbiological testing, and specifically to a drying and sterilization device and method for microbiological testing specimen slides. Background Technology

[0002] In the fields of microbiology, pathology, and clinical diagnosis, glass slides serve as the fundamental tools for carrying samples for microscopic observation. The cleaning, drying, and sterilization of slides after use are crucial for ensuring accurate test results and preventing cross-contamination. Currently, laboratories commonly use electrically heated forced-air drying ovens to dry cleaned slides in batches. While this method increases throughput to some extent, it has significant limitations: uneven hot air circulation inside the oven can lead to uneven heating of the slides, resulting in some areas being incompletely dried while others may overheat and affect slide performance; the entire process relies on manual timing and observation by operators, lacking precise timing and temperature control, resulting in poor repeatability; more importantly, traditional ovens only have a drying function, and sterilization requires a separate ultraviolet sterilizer or chemical immersion, disrupting the process. This not only increases operational steps and time consumption but also introduces the risk of secondary contamination and breakage during slide transfer.

[0003] Existing technologies have some drying devices, but they generally suffer from limited slide capacity, low efficiency of static drying methods, insufficient temperature control accuracy, uncontrollable drying time, and problems with drying uniformity. This leads to frequent batch changes during operation, making it difficult to achieve precise process control and intelligent management, which seriously restricts inspection efficiency. Summary of the Invention

[0007] In some embodiments, the slotted shaft is provided with a key, and the support frame is provided with a shaft hole along its length for the slotted shaft to pass through. The inner wall of the shaft hole is provided with a keyway that mates with the key. The support frame is connected to the detachable rotating shaft by a key connection.

[0008] In some embodiments, the slide mounting plate includes: Base plate; Two side plates are disposed opposite each other on both sides of the base plate along the length direction of the base plate; A limiting strip is provided on each of the side plates and extends continuously from one end to the other along the length direction of the side plate, and is suspended from the side plate toward the opposite side plate; a gap is provided between the limiting strips on the two side plates, and together with the side plate and the bottom plate, they form a mounting groove that is open at the top and both ends. A top plate extends along the length of the mounting groove and is movably disposed within the mounting groove; the width of the top plate is less than the distance between the side plates but greater than the distance between the upper limit strips of the two side plates. A first spring is disposed in the mounting groove, located between the top plate and the bottom plate; one end of the first spring is connected to the top plate, and the other end is connected to the bottom plate.

[0009] In some embodiments, the device includes a plurality of slide mounting plates, which are sequentially hinged together by hinges, and the two slide mounting plates located at the beginning and end are connected by pins.

[0010] In some embodiments, the slide mounting plate further includes: A hole is provided on the side of the top plate, with its axis horizontal and perpendicular to the direction of movement of the top plate; A second spring is disposed inside the hole, with one end fixedly connected to the bottom of the hole and the other end fixedly connected to a steel ball; the diameter of the hole is slightly larger than or equal to the diameter of the steel ball; when the second spring is in its natural state, the steel ball is partially located outside the hole. A through hole is provided on the side plate, with its axis horizontal and perpendicular to the direction of movement of the top plate; the diameter of the through hole is equal to or slightly smaller than that of the steel ball; A push rod is disposed in the through hole and slidably connected to the through hole, and its length is the same as the length of the through hole.

[0015] The technical solution of this invention provides multiple mounting surfaces through a support frame and, in conjunction with a detachable slide mounting plate, increases the slide capacity for single processing. Simultaneously, a drive motor rotates the entire supporting assembly at a uniform speed, ensuring that each slide receives alternating and uniform irradiation from the drying lamp and ultraviolet disinfection lamp, effectively avoiding localized overheating or disinfection dead zones, achieving a balance between large capacity and uniform processing effect. The introduction of a control module allows for the setting and automatic execution of key parameters such as drying temperature and time, enabling precise and programmable control of the drying process, reducing the arbitrariness and errors of manual operation, and ensuring consistent processing results. By integrating the drying and disinfection modules into the same housing and controlling them sequentially by the control module, the entire process from loading, drying to disinfection is automated and continuously integrated, simplifying operation steps, reducing slide transfer between devices, thereby improving overall processing efficiency, and mitigating the biosafety risks of secondary contamination, sample confusion, and personnel contact with potential pathogens caused by transfer.

[0019] The following provides a detailed description of specific embodiments of the present invention. It should be understood that the specific embodiments described herein are for illustrative and explanatory purposes only and are not intended to limit the scope of the invention.

[0020] In this invention, unless otherwise stated, directional terms such as "upper" and "lower" generally refer to the orientation in the assembled and used state. "Inner" and "outer" refer to the inner and outer sides relative to the outline of each component itself.

[0021] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate for the embodiments of the invention described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0022] The first aspect of this invention provides a drying and sterilization apparatus for microbial specimen slides, such as... Figures 1-4 As shown, the device mainly consists of a housing, a detachable rotating shaft 2, a support frame, a glass slide mounting plate 1, a drying module, a sterilization module, and a control module.

[0023] chassis The housing includes a housing wall and a cavity defined by the housing wall, the inner wall of which is preferably coated with a highly reflective aluminum or ceramic coating to enhance photothermal utilization efficiency.

[0024] Detachable rotating shaft 2 The chamber contains a detachable rotating shaft 2 driven by a drive motor. The detachable rotating shaft 2 includes a slotted short shaft 21 and a slotted shaft 22. The slotted short shaft 21 is connected to the output shaft of the drive motor via a coupling or directly. The connection between the slotted short shaft 21 and the slotted shaft 22 has a matching notch and aligned pin holes. The slotted short shaft 21 and the slotted shaft 22 are connected by a fixing pin 23 and a pin hole. The slotted shaft 22 has a key, and the support frame has a shaft hole along its length for the slotted shaft 22 to pass through. The inner wall of the shaft hole has a keyway that mates with the key. The support frame is connected to the detachable rotating shaft 2 via a key connection. The support frame achieves circumferential fixation and synchronous rotation through the keyway in its shaft hole mates with the key on the slotted shaft 22.

[0025] support frame The support frame is detachably mounted on the detachable rotating shaft 2 and forms multiple mounting surfaces that are rotationally symmetrical about the axis of the detachable rotating shaft 2. A slide mounting plate 1 is detachably mounted on the mounting surfaces, and the slide mounting plate 1 has multiple slide mounting positions extending axially along the detachable rotating shaft 2.

[0026] Those skilled in the art will understand that to support more slides, more faces can be provided on the support frame, such as a tetrahedron, pentahedron, or even more faces. In a preferred embodiment, the support frame has three mounting faces distributed at 120°, i.e., a triangular prism structure. When rotated, the triangular prism structure has a more uniform distribution of its center of mass and moment of inertia, reducing vibration and swaying. Simultaneously, in the trihedral structure, the angle between each slide mounting plate and the heat source / UV light source is larger (120° between adjacent faces), reducing the slide's own projection obstruction and allowing heat radiation and UV light to irradiate the slide surface more directly and evenly. In a tetrahedron or more faces, the slides are more upright, and slides on adjacent plates are more likely to form shadows, affecting the uniformity of drying and sterilization.

[0027] Slide Mounting Plate 1 Implementation Method 1: The slide mounting plate 1 includes a base plate, limiting strips, a top plate 101, a first spring 102, and two side plates 11. The two side plates are arranged opposite each other on both sides of the base plate along its length. A limiting strip is provided on each side plate 11 and extends continuously from one end to the other along its length, and is cantilevered from the side plate 11 toward the opposite side plate 11. A gap is provided between the limiting strips on both side plates 11, and together with the side plates 11 and the base plate 103, they form a mounting groove that is open at the top and both ends. The top plate 101 extends along the length of the mounting groove and is movably disposed within it. The width of the top plate 101 is less than the distance between the side plates 11 but greater than the distance between the limiting strips on both side plates 11, meaning that the top plate 101 and the side plates 11 are in a clearance-matched fit. The first spring 102 is disposed within the mounting groove, located between the top plate 101 and the base plate.

[0028] The function of the first spring 102 is to provide a continuous, adaptive clamping force. Theoretically, the first spring 102 should not be fixedly connected to any structure; one end should face the top plate 101, and the other end should face the bottom plate 103. However, in practice, this method of not being fixedly connected to any structure would cause the first spring 102 to tilt, which would be detrimental to the installation of the glass slide. Therefore, in a preferred embodiment of the present invention, at least one end of the first spring 102 is fixedly connected to the top plate 101 or the bottom plate 103.

[0029] In use, press down on the top plate 101 by hand, compressing the first spring 102 and forming a loading space between the upper surface of the top plate 101 and the lower surface of the limiting strip 106. Push the cleaned glass slides one by one into the mounting slot along the length of the base plate 103 from the end opening until the slot is full. Release the top plate 101, and the first spring 102 will spring back, firmly pressing the glass slides against the lower surface of the limiting strip 106 via the top plate 101.

[0030] Implementation Method Two: In Embodiment 1, when loading a glass slide, the top plate 101 needs to be continuously pressed to maintain an appropriate gap between the upper end of the top plate 101 and the lower end of the limiting strip, so as to facilitate the insertion of the glass slide. This design requires one hand to continuously press down on the top plate 101 while the other hand pushes the slide in. This operation is prone to causing operator fatigue in high-throughput, repetitive laboratory environments and affects the loading speed and neatness.

[0031] Based on this, the present invention provides another implementation method, namely, this second implementation method, specifically, as follows: Figure 5 As shown, based on Embodiment 1, the slide mounting plate 1 further includes a hole 101a, a second spring 101b, a through hole 11a, a steel ball 101c, and a push rod 11b.

[0032] A hole 101a is provided on the side of the top plate 101, with its axis horizontal and perpendicular to the direction of movement of the top plate 101. A second spring 101b is disposed within the hole 101a, with one end fixedly connected to the bottom of the hole 101a and the other end fixedly connected to a steel ball 101c. The diameter of the hole 101a is slightly larger than or equal to the diameter of the steel ball 101c. In the natural state, the steel ball 101c is partially located outside the hole 101a, preferably less than half of the steel ball 101c is located outside the hole 101a. A through hole 11a is provided on the side plate 11, with its axis horizontal and perpendicular to the direction of movement of the top plate 101. The diameter of the through hole 11a is equal to or slightly larger than the diameter of the steel ball 101c. A push rod 11b is disposed in the through hole 11a, slidably connected to the through hole, and its length is the same as the length of the through hole 11a.

[0033] When the top plate 101 is pressed down, the steel ball 101c is pushed out of the hole 101a and partially enters the through hole 11a under the action of the second spring 101b. The push rod 11b is pushed outward, and the steel ball 101c forms mechanical interference with the wall of the through hole 11a. At this time, the position of the top plate 101 is locked in the current pressed position, and a loading gap is formed between it and the limiting strip. At this time, the glass slide can be loaded freely with both hands without having to keep pressing down on the top plate 101. At this time, the end of the push rod 11b away from the steel ball 101c protrudes from the through hole 11a.

[0034] After the slide is loaded, the operator presses the end of the push rod 11b away from the steel ball 101c, pushing the push rod 11b toward the steel ball 101c, causing the steel ball 101c to disengage from the through hole 11a, thereby releasing the lock on the top plate 101. At this time, the top plate 101 will move toward the limiting strip under the action of the first spring 102 and press the slide.

[0035] During the release of the top plate 101, if the spring force of the first spring 102 is large, its speed of movement toward the limiting strip will be faster, and the resulting impact force will also be greater, which may break the glass slide. Therefore, when pressing the push rod 11b, the upward movement speed of the top plate 101 can be slowed down by hand to prevent the glass slide from being crushed.

[0036] Furthermore, the end of the push rod 11b facing the steel ball 101c must not protrude beyond the through hole 11a, otherwise it may extend into the hole 101a and thus block the upward movement of the top plate 101. Therefore, the through hole 11a is a countersunk hole. The push rod 11b is correspondingly designed as a stepped shaft structure including a head and a rod. The length of the push rod 11b head is equal to the depth of the countersunk hole head, thus serving as a limit. When the push rod 11b is fully pressed inward until its head end face is flush with the outer wall of the side plate 11, the end of its rod is exactly flush with the inner wall of the side plate 11, thereby ensuring that the push rod 11b does not overextend and obstruct the reset of the top plate 101, ensuring the final completion of the pressing action.

[0037] The design of the slide mounting plate 1 did not employ the common self-locking switch-type one-button locking / releasing scheme due to important considerations regarding the physical characteristics of the slide itself. When such a self-locking switch is triggered, its internal locking mechanism typically disengages instantaneously, causing the compressed drive spring, i.e., the main first spring 102, to release its force completely in a very short time, pushing the top plate 101 upwards with high acceleration and speed. This rapid, uncontrolled upward impact would subject the slide to a large dynamic load instantaneously, posing a significant risk of crushing or edge chipping for thin and brittle glass slides.

[0038] Based on this, the preferred embodiment proposed in this invention, particularly the technical solution with push rod 11b, provides a safer and more reliable technical approach. This solution uses an independent push rod 11b for unlocking, allowing the operator to control the rhythm of the unlocking action. After pressing the push rod 11b inward to release the constraint on the steel ball 101c, although the force of the first spring 102 is released, the operator can effectively buffer and slow down the rising speed of the top plate 101 by applying pressure to it with their hand, thereby controlling the upward impact force within a safe range and avoiding the problem of glass slide breakage due to the mechanism's automatic rapid reset.

[0039] Connection method between slide mounting plates 1 Method 1: The device includes multiple slide mounting plates 1, which are sequentially hinged together by hinges 12, with the first and last slide mounting plates 1 connected by pins 13. In this embodiment, the sides of the multiple slide mounting plates 1 are sequentially hinged in pairs by hinges 12 to form a trihedral chain plate structure. The two mounting plates 1 at the beginning and end of the chain are connected by a pluggable pin 13, so that the entire chain plate forms a stable triangular prism when retracted. When it is necessary to load or unload slides, simply remove the pin 13 to fully unfold the entire trihedral structure into an approximately planar state. The operator can simultaneously load or remove slides from all three mounting plates 1 on a single plane. After loading, the slides are installed on the support frame and locked by inserting the pin 13.

[0040] Method 2: The device includes multiple independent slide mounting plates 1. Each slide mounting plate 1 has a connecting lug with a through hole on its side edge, and the through hole on the lug forms a pin hole. By inserting a pin into the pin hole of two adjacent slide mounting plates 1, a detachable hinge can be achieved between them. Based on this structure, when loading slides, the operator can completely disassemble all slide mounting plates 1 into independent units and load slides separately, with ample operating space and no interference between them. After loading, they are hinged together in pairs by pins, forming only a hinge chain, which is not closed at the beginning and end. Finally, when installing this hinge chain to the corresponding mounting surface of the support frame, the first and last slide mounting plates 1 are connected by pins to form a complete ring-shaped rotating body for operation. This design enhances the flexibility of loading operations and the convenience of modular maintenance.

[0041] Method 3: The device includes multiple slide mounting plates 1, and adjacent slide mounting plates 1 are connected by pins. In this embodiment, each slide mounting plate 1 is a completely independent unit. Each slide mounting plate 1 has a connecting lug with a through hole on its edge side. Each mounting surface of the support frame has a corresponding connecting seat. By using an independent pin passing through the lug and the connecting seat, each mounting plate 1 can be rotatably suspended on the support frame. In this embodiment, the operator can select to install one, two, or three slide mounting plates 1 according to the current processing volume, without having to use all of them every time. If a slide mounting plate 1 is damaged, it can be replaced individually, reducing maintenance costs. Installing and removing a single plate does not affect other plates, providing high flexibility.

[0042] Drying module and sterilization module The drying module includes a drying lamp 4 disposed inside the housing and facing the slide mounting plate 1. The drying lamp 4 may be an infrared heating lamp or a quartz heating tube. The disinfection module includes an ultraviolet disinfection lamp 5 disposed inside the housing and facing the slide mounting plate 1.

[0043] Control module The control module is electrically connected to the drive motor, the drying module, and the disinfection module, respectively, and is used to execute the drying and disinfection programs. The control module is based on a programmable logic controller (PLC). Its input unit is connected to a touch-screen control panel 3 for parameter setting, program selection, and manual control; a PT100 temperature sensor for real-time temperature monitoring and PID adjustment; and a door status sensor for safety interlocking. Its output unit is connected to a drive motor frequency converter for adjusting rotation speed, a solid-state relay (SSR) for the drying lamp 4, a relay for controlling on / off switching and power adjustment, a relay for the ultraviolet disinfection lamp 5, and an audible and visual alarm.

[0044] The PLC has pre-stored standard drying and sterilization programs, and users can also customize multiple curves. During operation, the PLC controls the inverter to drive the motor at a constant speed according to the set values, while simultaneously controlling the power of the drying lamp 4 via the SSR to stabilize the cavity temperature at the set value. Time control is accurate to the second. For safety, when the door is opened, the door status sensor signal is immediately interrupted, and the PLC will instantly cut off the power to the drying lamp 4, the ultraviolet sterilization lamp 5, and the drive motor to ensure absolute safety.

[0045] In addition, the present invention also provides a method for drying and sterilizing glass slides for microbial testing, comprising the following steps: Disassemble the detachable rotating shaft 2, or separate the detachable rotating shaft 2 from the support frame; The glass slide to be processed is loaded into the glass slide mounting station of the glass slide mounting plate 1; Reinstall the slide mounting plate 1 onto the mounting surface of the support frame, and / or restore the connection of the detachable rotating shaft 2; The drying and disinfection parameters are set through the control module. The device is started, causing the drive motor to drive the support frame and the slide mounting plate 1 to rotate at a constant speed around the axis of the detachable rotating shaft 2; during the rotation, the drying module is started to heat and dry the slide, and the drying module is automatically turned off after the set drying time is reached; After the drying step is completed, the disinfection module is automatically started to disinfect the glass slide with ultraviolet light, and after the set disinfection time is reached, the disinfection module is automatically turned off and the drive motor is stopped.

[0046] The apparatus and method of this invention provide multiple mounting surfaces through a support frame and, in conjunction with a detachable slide mounting plate, increase the slide capacity for single processing. Simultaneously, a drive motor rotates the entire supporting assembly at a uniform speed, ensuring that each slide receives alternating and uniform irradiation from the drying lamp and ultraviolet disinfection lamp, effectively preventing localized overheating or disinfection dead zones, achieving a balance between large capacity and uniform processing. The introduction of a control module allows for the setting and automatic execution of key parameters such as drying temperature and time, enabling precise and programmable control of the drying process, reducing the arbitrariness and errors of manual operation, and ensuring consistent processing results. By integrating the drying and disinfection modules within the same housing and controlling them sequentially by the control module, the entire process from loading and drying to disinfection is automated and continuously operated, simplifying operational steps, reducing slide transfer between devices, thereby improving overall processing efficiency, and mitigating the biosafety risks of secondary contamination, sample confusion, and personnel contact with potential pathogens caused by transfer.

[0047] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the specific details in the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0048] 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. To avoid unnecessary repetition, the present invention will not describe the various possible combinations separately.

[0049] Furthermore, various different embodiments of the present invention can be combined in any way, as long as they do not violate the spirit of the present invention, they should also be regarded as the content disclosed by the present invention.
