Pathology slide disinfection device and control method

Abstract

This invention relates to the field of disinfection devices, and particularly to a pathological slide disinfection device and control method. This application discloses a pathological slide disinfection device and control method in which disinfectant enters through perforations in multiple sample trays via a structural tube and then flows into the channel grooves. The pathological slide disinfection device and control method provided by this invention completes the disinfection process as the disinfectant passes through the slide. When a certain volume of disinfectant is injected, it submerges all sample trays, completing a more thorough disinfection process. Disinfectant remains only in the channel grooves on the sample trays, thus reducing the amount of disinfectant used. The sample trays rotate in different directions, causing changes in the position of the slides along the width of the channel grooves, and altering the relative position between the slides and the support strips, thus thoroughly completing the disinfection. After disinfection, the operation of a motor causes the disinfectant in the sample trays to be ejected.

Description

Technical Field

[0001] This invention relates to the field of disinfection devices, and in particular to a disinfection device and control method for pathological slides. Background Technology

[0002] In existing technologies, medical pathology is an important branch of medicine, primarily studying the nature, etiology, development process, and impact on the body of diseases. Through microscopic analysis of diseased tissues or cells, pathology provides a basis for disease diagnosis and treatment planning. Pathological slides are crucial in pathological diagnosis, serving as an important tool for diagnosing diseases such as malignant tumors, inflammation, and infections. Pathologists make accurate diagnoses by observing tissue samples.

[0003] Pathology slides are widely used in medical research and teaching. They are used to study disease mechanisms, develop new therapies and drugs, and are also used in medical student education to help them grasp pathological features. Pathology slides are made of high-quality glass or transparent materials and hold processed biological tissue samples for easy microscopic observation. They are classified into ordinary slides and coverslips according to usage requirements; the former holds the sample, while the latter covers it to improve image quality.

[0004] However, there are problems with the handling and use of pathology slides. Improper disposal of waste slides can pollute the environment and spread diseases. Sterilization requires a large amount of manpower because slides are fragile and can easily cut workers, and traditional sterilization methods are inefficient, consume a lot of liquid, and are costly. Slides are prone to stacking during sterilization, leading to incomplete sterilization and increasing the risk of disease transmission. Although special clamping tools can be used for sterilization, this makes the process more complicated and increases the possibility of incomplete sterilization. Summary of the Invention

[0005] The main objective of this invention is to provide a pathological slide disinfection device and control method, aiming to solve the problems of low efficiency, high liquid consumption, high cost, easy stacking, and incomplete disinfection during the slide disinfection process.

[0006] To achieve the above objectives, the present invention provides a pathological slide sterilization device, comprising:

[0007] Organism;

[0008] The barrel body is installed on the machine body and has a conduit with a switch on the bottom. A support plate is also rotatably installed at the bottom of the barrel body.

[0009] Multiple sample trays are stacked on the support plate. The outer periphery of the sample tray is clearance-fitted with the inner wall of the barrel. The upper and lower surfaces of the sample trays are shaped to match each other. The sample trays are annular with a perforation in the center. The upper surface of the sample trays is provided with multiple radially penetrating flow channels. The width of the flow channels is greater than that of the glass slide. At the bottom of the flow channels, multiple support strips are spaced apart in the width direction and arranged along the length direction. The support strips are provided with corresponding glass slides and have a thickness greater than that of the glass slides.

[0010] The cover assembly includes a motor, a structural tube, an upper cover plate, and a lower cover plate. The upper part of the structural tube in the height direction is rotatably fixed to the upper cover plate, while the lower part in the height direction is fixed to the lower cover plate. The motor is fixed to the upper cover plate and its output end drives the structural tube to rotate. The middle part of the structural tube is a channel. The lower surface of the lower cover plate is shaped to match the upper surface of the sample disk. The lower end of the structural tube is shaped to match the perforation of the sample disk.

[0011] A linear drive is mounted on the machine body and its output is connected to the motor.

[0012] The disinfectant pumping unit has an output end that forms a circumferentially free and detachable connection with the upper end of the structural tube.

[0013] Furthermore, the disinfectant pumping unit includes a fixed column, and the output end of the disinfectant pumping unit is a fixed ring. The fixed ring is adjustable in height, the outer diameter of the fixed ring matches the inner diameter of the structural tube, and a sealing ring is provided on the outer wall of the fixed ring corresponding to the position of the structural tube.

[0014] Furthermore, the sample disk is generally shaped like a disk with a lower inner surface and a higher outer surface.

[0015] Furthermore, adjacent sample trays are detachably connected in thickness, the lowermost sample tray is detachably connected to the support plate, and the lower cover plate is detachably connected to the uppermost sample tray.

[0016] Furthermore, the pathological slide sterilization device also includes an air supply unit, the output end of which is detachably connected to the upper end of the structural tube.

[0017] Furthermore, the output end of the air supply unit and the upper end of the structural tube form a circumferentially free and detachable connection.

[0018] Furthermore, a heating section is provided corresponding to the air supply section, and the airflow output from the air supply section enters the structural tube after passing through the heating section.

[0019] Furthermore, a liquid reservoir is connected to the corresponding conduit.

[0020] Furthermore, an ultrasonic transducer is provided at the bottom of the barrel.

[0021] This invention provides a control method applied to the above-mentioned pathological slide sterilization device, comprising:

[0022] The linear drive is controlled to lower the cover assembly.

[0023] Control the switch to turn off;

[0024] The disinfectant pump unit is activated to input a preset volume of disinfectant;

[0025] Control the motor to reciprocate;

[0026] Stop the operation of the disinfectant pumping unit and control the switch to open;

[0027] Control the motor to stop working.

[0028] The pathological slide disinfection device and control method provided by this invention involve the disinfectant entering the flow channel groove through perforations on multiple sample trays via a structural tube. The disinfectant completes the disinfection process as it passes through the slide. When a certain volume of disinfectant is injected, it will submerge all sample trays, completing a more thorough disinfection process. Disinfectant will only be present in the flow channel groove on the sample trays, thus reducing the amount of disinfectant used. The sample trays rotate in different directions, causing the position of the slide in the width direction of the flow channel groove to change, and the relative position between the slide and the support strip to change, thus thoroughly completing the disinfection. After disinfection, the operation of the motor causes the disinfectant in the sample trays to be ejected. Attached Figure Description

[0041] Reference Figures 1 to 8 In one embodiment of the present invention, a pathological slide sterilization device includes:

[0042] Body 100;

[0043] The barrel 200 is installed on the machine body 100 and has a conduit 211 with a switch 210 installed on the bottom. A support plate 220 is also rotatably installed at the bottom of the barrel 200.

[0044] Multiple sample trays 300 are stacked on the support plate 220. The outer periphery of the sample tray 300 is clearance-fitted with the inner wall of the barrel 200. The upper and lower surfaces of the sample tray 300 are shaped to match each other. The sample tray 300 is annular with a perforation 310 in the center. Multiple radially penetrating flow channels 320 are provided around the upper surface of the sample tray 300. The width of the flow channels 320 is greater than that of the glass slide 010. Multiple support strips 330 are provided at intervals in the width direction and are provided along the length direction at the bottom of the flow channels 320. The support strips 330 are provided with corresponding slots 331 for the glass slide 010 and are thicker than the glass slide 010.

[0045] The cover assembly 400 includes a motor 410, a structural tube 420, an upper cover plate 430, and a lower cover plate 440. The upper part of the structural tube 420 is rotatably fixed to the upper cover plate 430 in the height direction, while the lower part of the structural tube 420 is fixed to the lower cover plate 440 in the height direction. The motor 410 is fixed to the upper cover plate 430 and its output end drives the structural tube 420 to rotate. The middle part of the structural tube 420 is a channel 421. The lower surface of the lower cover plate 440 is shaped to match the upper surface of the sample disk 300. The lower end of the structural tube 420 is shaped to match the perforation 310 of the sample disk 300.

[0046] A linear drive 500 is installed on the machine body 100 and its output is connected to the motor 410;

[0047] The disinfectant pumping unit 600 has its output end connected to the upper end of the structural tube 420 in a circumferentially free and detachable manner.

[0048] In existing technologies, the disinfection process of glass slides often requires a large amount of human resources. Due to the fragile nature of the slides, workers' fingers are easily cut during the operation, posing a safety hazard. Traditional disinfection methods are inefficient and consume a large amount of disinfectant, increasing medical costs. More importantly, slides are prone to layering during the disinfection process, resulting in incomplete disinfection and increasing the risk of disease transmission.

[0049] The pathological slide disinfection device provided by the present invention includes a body 100, a barrel 200, multiple sample trays 300, a cover assembly 400, a linear drive 500, and a disinfectant pumping unit 600.

[0050] The body 100 serves as the structural basis.

[0051] A barrel 200 is mounted on the machine body 100 and its bottom is connected to a conduit 211 with a switch 210 mounted on it. The opening and closing of the switch 210 controls the flow of fluid through the conduit 211. When the conduit 211 is open, the barrel 200 is connected to the outside, allowing fluid to overflow from the barrel 200; when the conduit 211 is closed, the barrel 200 is isolated from the outside. A support plate 220 is rotatably mounted on the bottom of the barrel 200. The support plate 220 is connected to the bottom of the barrel 200 via bearings, allowing it to rotate within a plane.

[0052] Multiple sample trays 300 are stacked on a support plate 220. The outer periphery of the sample tray 300 is clearance-fitted with the inner wall of the barrel 200. The upper and lower surfaces of the sample tray 300 are shaped to fit together during stacking. The sample tray 300 is annular with a perforation 310 in the center. Multiple radially penetrating flow channels 320 are circumferentially formed on the upper surface of the sample tray 300. The width of the flow channels 320 is greater than that of the glass slide 010, for example, 0.3 to 1.0 cm wider than the width of the glass slide 010. Multiple support strips 330, spaced apart along the width direction and extending along the length direction, support the glass slide 010. Each support strip 330 has a corresponding locking position 331, thicker than the glass slide 010. The length of the locking position 331 is equal to or greater than the length of the glass slide 010. When the slide 010 is installed in the slots 331 of the multiple support bars 330, the upper surface of the slide 010 sinks into the upper surface of the sample tray 300, allowing the upper surface of the slide 010 to be treated with disinfectant. Multiple slides 010 are placed in the flow channels 320 of the sample tray 300 and supported by the multiple support bars 330. The slides 010 are free in the width direction, allowing their position to change when the sample tray 300 rotates in different directions, preventing the relative position between the slide 010 and the support bars 330 from being fixed and thus ensuring thorough disinfection of the contact area. When one sample tray 300 is full of slides 010, the next sample tray 300 is placed on top. Because the upper surface of the slide 010 sinks into the upper surface of the sample tray 300, the upper surface of the slide 010 will not contact the lower surface of the sample tray 300. The multiple sample trays 300 can be fixed in the thickness direction by friction or a locking structure. If the disinfectant is only present in the flow channel 320 on the sample tray 300, then the amount of disinfectant used is reduced.

[0053] The cover assembly 400 includes a motor 410, a structural tube 420, an upper cover plate 430, and a lower cover plate 440. The upper cover plate 430 is rotatably fixed to the upper part of the structural tube 420 in the height direction. For example, the upper cover plate 430 is connected to the upper part of the structural tube 420 in the height direction via a plane bearing, allowing them to rotate relative to each other. The lower cover plate 440 is fixed to the lower part of the structural tube 420 in the height direction. The motor 410 is fixed to the upper cover plate 430, and its output drives the structural tube 420 to rotate. The output of the motor 410 and the structural tube 420 can be linked by a synchronous belt, gears, or a belt. The middle part of the structural tube 420 is a cylindrical channel 421. The lower surface of the lower cover plate 440 is shaped to match the upper surface of the sample tray 300, so that the lower cover plate 440 can cover the surface of the uppermost sample tray 300. When the cover assembly 400 is pressed down, the lower cover plate 440 can cover the surface of the uppermost sample plate 300. At this time, the structural tube 420 is connected to the perforations 310 that pass through the multiple sample plates 300. The fluid introduced from the upper part of the structural tube 420 can enter the flow channel groove 320 through the perforations 310 of the sample plates 300.

[0054] The linear drive 500 is mounted on the body 100 and its output is connected to the motor 410. The linear drive 500 drives the cover assembly 400 to rise and fall. The linear drive 500 can operate in a hydraulic, pneumatic, or electric motor-driven manner.

[0055] The output end of the disinfectant pumping unit 600 is circumferentially free and detachably connected to the upper end of the structural tube 420. The output end of the disinfectant pumping unit 600 is first connected to the upper end of the structural tube 420; then the two can rotate freely relative to each other in the circumferential direction; finally, a seal is formed between the two, otherwise leakage will occur.

[0056] During the work process:

[0057] The glass slide 010 is placed in the flow channel 320 of the sample tray 300 and is constrained by the support bar 330. The sample tray 300 is placed on the support plate 220. Multiple sample trays 300 can also be stacked on the sample tray 300.

[0058] The linear drive 500 is controlled to work and lower the cover assembly 400. At this time, the lower cover plate 440 fixes the multiple sample trays 300.

[0059] When control switch 210 is closed, fluid will not overflow after entering the tank 200.

[0060] Connect the output end of the disinfectant pump unit 600 to the upper end of the structural tube 420. Start the disinfectant pump unit 600 to input a preset volume of disinfectant. At this time, the disinfectant enters through the structural tube 420 into the perforations 310 on multiple sample trays 300, and then into the flow channel 320. The disinfectant completes the disinfection process as it passes through the glass slide 010. When a certain volume of disinfectant has been injected, it will submerge all the sample trays 300, completing a more thorough disinfection process. Disinfectant will only be present in the flow channel 320 on the sample trays 300, thus reducing the amount of disinfectant used.

[0061] After the disinfectant pumping unit 600 starts working, the control motor 410 reciprocates, the sample tray 300 rotates in different directions, the position of the glass slide 010 in the width direction of the flow channel 320 can change, and the relative position between the glass slide 010 and the support strip 330 changes, thus thoroughly completing the disinfection.

[0062] The disinfectant pump unit 600 is stopped and the control switch 210 is opened, at which point the disinfectant overflows and is stored. During this process, the motor 410 continues to operate, and the disinfectant in the sample tray 300 is ejected.

[0063] Once the disinfectant is removed from the sample tray 300, the control motor 410 stops working.

[0064] In summary, the upper surface of the sample tray 300 is provided with multiple radially penetrating flow channels 320. At the bottom of the flow channels 320, multiple support bars 330 are spaced apart in the width direction and arranged along the length direction. The output end of the disinfectant pump 600 forms a circumferentially free and detachable connection with the upper end of the structural tube 420. The disinfectant enters the flow channels 320 through the perforations 310 on the multiple sample trays 300 via the structural tube 420. The disinfection process is completed as the disinfectant passes through the glass slide 010. When a certain volume of disinfectant is injected, it will submerge all the sample trays 300, completing a more thorough disinfection process. Disinfectant will only be present in the flow channels 320 on the sample trays 300, thus reducing the amount of disinfectant used. The sample trays 300 rotate in different directions, causing the position of the glass slide 010 in the width direction of the flow channels 320 to change, and the relative position between the glass slide 010 and the support bars 330 to change, thoroughly completing the disinfection. After disinfection, the operation of the motor 410 causes the disinfectant in the sample trays 300 to be ejected.

[0065] Reference Figures 1 to 8 In one embodiment, the disinfectant pumping unit 600 includes a fixed column 620, and the output end of the disinfectant pumping unit 600 is a fixed ring 610. The fixed ring 610 is height-adjustable, the outer diameter of the fixed ring 610 matches the inner diameter of the structural tube 420, and a sealing ring is provided on the outer wall of the fixed ring 610 corresponding to the position of the structural tube 420.

[0066] In this embodiment, a method is provided for connecting the disinfectant pumping unit 600 and the structural tube 420. The two are sleeved together and sealed by a sealing ring. Separation and connection are achieved by adjusting the height of the fixing ring 610 on the fixing post 620. Alternatively, the fixing post 620 itself is linearly driven, and the height of the fixing ring 610 is adjusted by telescopic action.

[0067] Reference Figure 5 In one embodiment, the sample disk 300 is generally shaped like a disk with a lower inner surface and a higher outer surface.

[0068] In this embodiment, the sample tray 300 is generally tray-shaped, and its upper surface has an upward slope from the inside out. Similarly, the flow channel 320 also has an upward slope from the inside out. As the disinfectant flows through the flow channel 320, it flows upward and overflows, allowing for more thorough contact between the disinfectant and the glass slide 010.

[0069] Reference Figure 3 In one embodiment, adjacent sample trays 300 are detachably connected between their thicknesses, the lowermost sample tray 300 is detachably connected to the support plate 220, and the lower cover plate 440 is detachably connected to the uppermost sample tray 300.

[0070] In this embodiment, detachable structures, such as snap-fit ​​connections, are formed between adjacent sample trays 300, between the lower cover plate 440 and the sample tray 300, and between the sample tray 300 and the support plate 220. Compared to providing fixing force through friction generated by compression, introducing specific fixing structures ensures stable fixation between the components, which is particularly important during rotation.

[0071] In one embodiment, the pathological slide sterilization device further includes an air supply unit, the output end of which is detachably connected to the upper end of the structural tube 420.

[0072] In this embodiment, the drying process of the glass slide 010 is completed by providing high-pressure airflow through the operation of the air supply unit. The air supply unit can be an impeller type or a rotor type; the specific operating method is not the focus, as long as it can provide airflow. The operation of the motor 410 can be stopped before connecting the air supply unit to the upper end of the structural tube 420 and then starting the operation of the air supply unit.

[0073] In one embodiment, the output end of the air supply unit is circumferentially free and detachably connected to the upper end of the structural tube 420.

[0074] In this embodiment, by restricting the connection between the output end of the air supply unit and the structural tube 420, the air supply unit can maintain its connection with the structural tube 420 during rotation. During the rotation of the structural tube 420, the sample disk 300 rotates simultaneously (intermittently rotating in both directions). At this time, the glass slide 010 is in a relatively unstable state, allowing the high-pressure airflow from the air supply unit to provide a better drying effect. For example, if the output end of the air supply unit is made of rigid material and has a sealing ring on its outer periphery, and the output end of the air supply unit is inserted into the structural tube 420, a circumferentially free and sealed fit is formed.

[0075] In one embodiment, a heating section is provided corresponding to the air supply section, and the airflow output from the air supply section enters the structural tube 420 after passing through the heating section.

[0076] In this embodiment, a heating element is provided corresponding to the air supply section to increase the temperature of the high-pressure airflow output from the air supply section, thereby improving the drying effect. The heating element can operate in various ways, such as resistance heating. In a specific implementation, a heating chamber is added at the output pipe of the air supply section, and a resistance heating element is installed inside the heating chamber to form the heating element.

[0077] In one embodiment, the bottom and upper part of the barrel 200 are respectively equipped with multiple ultraviolet light generators, wherein the sample plate 300 is made of ultraviolet-transmitting material.

[0078] In this embodiment, the disinfection effect is enhanced by introducing multiple ultraviolet (UV) light generators. The UV light generators can be gas discharge type, semiconductor type, or laser type, etc., preferably semiconductor type. The upper and lower UV light generators respectively disinfect the upper and lower surfaces of the glass slide 010. The sample tray 300 is made of a material that meets UV transmittance requirements and is preferably thin, so that the sample tray 300 does not significantly reduce the disinfection effect of the UV light. For example, the sample tray 300 can be made of quartz glass.

[0079] In one embodiment, a liquid tank is connected to the conduit 211.

[0080] In this embodiment, considering that in some cases cleaning liquids and disinfecting liquids need to be sealed and stored, a liquid tank is provided for the corresponding conduit 211 to perform the storage effect.

[0081] In one embodiment, an ultrasonic transducer is provided at the bottom of the barrel 200.

[0082] In this embodiment, the ultrasonic transducer introduces a cavitation effect, which makes the contact between the clean water or disinfectant and the glass slide 010 intense and sufficient, thereby improving the cleaning and disinfection effect.

[0083] The present invention also provides a control method applied to the above-mentioned pathological slide sterilization device, comprising:

[0084] The linear drive 500 is controlled to operate, thereby lowering the cover assembly 400;

[0085] Control the switch 210 to close;

[0086] The disinfectant pump unit 600 is activated to input a preset volume of disinfectant;

[0087] Control the motor 410 to reciprocate;

[0088] Stop the operation of the disinfectant pumping unit 600 and control the switch 210 to open;

[0089] Control the motor 410 to stop working.

[0090] In this embodiment, the glass slide 010 is placed in the flow channel 320 of the sample tray 300 and is constrained by the support bar 330. The sample tray 300 is placed on the support plate 220. Multiple sample trays 300 can also be stacked on the sample tray 300.

[0091] The linear drive 500 is controlled to work and lower the cover assembly 400. At this time, the lower cover plate 440 fixes the multiple sample trays 300.

[0092] When control switch 210 is closed, fluid will not overflow after entering the tank 200.

[0093] Connect the output end of the disinfectant pump unit 600 to the upper end of the structural tube 420. Start the disinfectant pump unit 600 to input a preset volume of disinfectant. At this time, the disinfectant enters through the structural tube 420 into the perforations 310 on multiple sample trays 300, and then into the flow channel 320. The disinfectant completes the disinfection process as it passes through the glass slide 010. When a certain volume of disinfectant has been injected, it will submerge all the sample trays 300, completing a more thorough disinfection process. Disinfectant will only be present in the flow channel 320 on the sample trays 300, thus reducing the amount of disinfectant used.

[0094] After the disinfectant pumping unit 600 starts working, the control motor 410 reciprocates, the sample tray 300 rotates in different directions, the position of the glass slide 010 in the width direction of the flow channel 320 can change, and the relative position between the glass slide 010 and the support strip 330 changes, thus thoroughly completing the disinfection.

[0095] The disinfectant pump unit 600 is stopped and the control switch 210 is opened, at which point the disinfectant overflows and is stored. During this process, the motor 410 continues to operate, and the disinfectant in the sample tray 300 is ejected.

[0096] Once the disinfectant is removed from the sample tray 300, the control motor 410 stops working.

[0097] In summary, the pathological slide disinfection device and control method provided by this invention allow the disinfectant to enter the perforations 310 on multiple sample trays 300 through the structural tube 420 and then into the flow channel 320. The disinfectant completes the disinfection process as it passes through the slide 010. When a certain volume of disinfectant is injected, it will submerge all the sample trays 300, completing a more thorough disinfection process. Disinfectant will only be present in the flow channel 320 on the sample trays 300, thus reducing the amount of disinfectant used. The sample trays 300 rotate in different directions, and the position of the slide 010 in the width direction of the flow channel 320 can change. The relative position between the slide 010 and the support strip 330 changes, thoroughly completing the disinfection. After disinfection, the operation of the motor 410 causes the disinfectant in the sample trays 300 to be ejected.

[0098] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
