Technical Field
[0001] This invention relates to the field of glass slide storage equipment technology, and in particular, to a medical glass slide storage device. Background Technology
[0002] When hospitals analyze the etiology and pathology of patients, the most common examination method is to use a microscope to examine bodily fluids such as blood and urine. Currently, after obtaining a patient's blood or urine sample, the laboratory personnel first drop it onto a glass slide, then examine it under a microscope. Traditionally, medical slides are stored in simple boxes or drawers, resulting in a rudimentary management method that heavily relies on manual record-keeping.
[0003] The above-mentioned storage mode of glass slides has certain problems: 1. After the glass slides are taken out, they are easily confused and lost due to record omissions, and it is difficult to trace them when the sample size is large and the loan time is long; 2. Manually searching for and registering the loan information of glass slides is inefficient and increases the workload of medical staff. Summary of the Invention
[0004] This invention provides a medical slide preservation device to solve the technical problems of existing slide storage methods, which are that slides are easily confused and lost due to record-keeping oversights after being taken out, and that tracing is difficult when the sample size is large and the loan period is long; manual searching and registration of slide loan information is inefficient and increases the workload of medical staff.
[0005] The technical solution adopted in this invention is as follows:
[0006] A medical slide preservation device includes: a storage box that can be opened and closed; a control panel connected to the outside of the storage box for automatically unlocking the storage box after inputting the information of the person retrieving the slide; a scissor-type lifting mechanism disposed inside the storage box and capable of being pulled out upwards or pushed back downwards under external force; multiple slide storage boxes stacked vertically on the scissor-type lifting mechanism; multiple sets of elastic slide clamping mechanisms arranged sequentially along the transverse direction of the slide storage boxes; a self-propelled inkjet printing mechanism disposed inside the storage box; and a cotton wiping component disposed along the transverse direction of the storage box on one side inside the storage box. Each set of elastic slide clamping mechanisms is used to cooperate with the slide storage box to elastically clamp one slide. Each elastic slide clamping mechanism includes an inkjet plate located outside the slide storage box, the inkjet plate being used to clamp the slide. During the process of moving in and out of the storage box, the slide will not come into contact with the cotton wiping component. The self-propelled inkjet printing mechanism is connected to the control panel. After starting, it will automatically move to the side of the slide to be retrieved selected by the system and connect to the inkjet plate at the corresponding position. This will pull the slide elastic clamping mechanism to move away from the outside of the slide storage box to release the clamped slide and make the slide to be retrieved automatically pop up. The self-propelled inkjet printing mechanism is also used to print lending information on the inkjet plate during the process of pulling the slide elastic clamping mechanism to move outward. After the lending information is printed and the slide to be retrieved automatically pops up, the inkjet plate is released and automatically returns to its position. The slide elastic clamping mechanism is also used to retract into the inside of the slide storage box under the action of elastic force after the slide is taken out, so as to avoid the inkjet plate from contacting the cotton wiping component during the process of the slide storage box moving in and out of the storage box.
[0007] Furthermore, the first longitudinal side of the slide storage box is provided with several partitions, which are arranged sequentially and spaced apart along the transverse side of the slide storage box so that the gap between adjacent partitions forms a slot for holding the slide on the first side. The inner wall of the first side of the slide storage box is also provided with a groove connecting each slot, and the upper end of the groove extends to the top of the slide storage box, while the lower end of the groove is higher than the bottom of the slide. The slide elastic clamping mechanism also includes a cooperating elastic clamping mechanism and an elastic support mechanism.

The two first limiting blocks are simultaneously fixedly connected to the inkjet plate. The L-shaped clamping plate cooperates with the corresponding slot to press down and clamp the slide. The elastic support mechanism includes a support base plate located at the bottom of the slide to support the slide, two second guide rods arranged vertically and slidingly passing through the bottom plate of the slide storage box, two second springs fixed to the two second guide rods, and two second limiting blocks fixed to the outer ends of the two second guide rods. The top ends of the two second guide rods are respectively fixedly connected to the support base plate, and the two ends of the second springs are limited between the support base plate and the bottom plate of the slide storage box.
[0009] Furthermore, the cotton swab component includes a cotton swab mounting plate fixed to one side of the storage box outlet, and a cotton swab fixed to the cotton swab mounting plate, with the cotton swab facing the side of the slide storage box; the inkjet plate is also printed with indelible positioning marks for indicating the storage position of the slides.
[0010] Furthermore, the self-propelled inkjet printing mechanism includes a sliding mounting base, a sliding drive mechanism disposed inside the storage box and connected to the sliding mounting base to drive the sliding mounting base to move laterally and vertically along the storage box, a miniature inkjet printer and a miniature electric push rod respectively fixed on the sliding mounting base, and a push plate connected to the telescopic end of the miniature electric push rod for connecting the inkjet plate; the sliding drive mechanism, the miniature inkjet printer and the miniature electric push rod are respectively connected to the control panel.
[0011] Furthermore, the sliding drive mechanism includes a vertically arranged slide rail that slides laterally along the storage box, a first lead screw disposed in a vertical groove on the slide rail, a first servo motor disposed at the bottom end of the slide rail and connected to the first lead screw, a second lead screw that rotates laterally within the storage box, and a second servo motor disposed within the storage box and connected to the second lead screw, wherein the first servo motor and the second servo motor are respectively connected to the control panel; a sliding mounting seat is threaded onto the outer circle of the first lead screw; and the bottom end of the slide rail is threaded onto the outer circle of the second lead screw.
[0012] Furthermore, the scissor lift mechanism includes two sets of scissor lift frames disposed on the lateral sides of the storage box; each lateral side of the slide storage box is provided with a concave sliding groove, and each lateral side of the storage box bottom plate is also provided with a concave sliding groove, and the sliding grooves extend along the longitudinal direction of the storage box; the scissor lift frames are slidably connected to the sliding grooves of the slide storage box and the storage box respectively through a first slider and a second slider.
[0013] Furthermore, the scissor lift mechanism also includes a lifting and locking mechanism, which includes a positioning rod arranged laterally and slidingly passing through the second slider, a movable plate fixed to the inner end of the positioning rod, a third guide rod arranged laterally and slidingly passing through the movable plate, a third limiting block fixed to the inner end of the third guide rod, a third spring fitted on the outer circle of the third guide rod and with both ends respectively limited between the third limiting block and the movable plate, and a reset block; the outer end of the third guide rod is fixedly connected to the second slider; a positioning hole is also provided through the side wall of the storage box, and the reset block is inserted into the positioning hole from the outside of the storage box. The positioning hole is also used for the positioning rod to be inserted to lock the scissor lift during the lifting and lowering process of the scissor lift frame.
[0014] Furthermore, a pull plate is connected to the top slide storage box; except for the bottom slide storage box, each of the bottom corners of the other slide storage boxes is fixedly connected with a vertically arranged movable rod and a fourth limiting block fixed to the bottom of the movable rod; except for the top slide storage box, each edge of the other slide storage boxes is provided with a movable hole extending inward from the top, and the movable rod connected to the bottom of the upper slide storage box is slidably installed in the corresponding movable hole of the lower slide storage box, and the movable rod is restricted from being pulled upward out of the movable hole by the fourth limiting block.
[0015] Furthermore, the storage box includes a hollow box body, a lid hinged to one side of the box body for closing the upper opening of the box body, a handle fixed to the top of the lid, and an electronic lock connected to the lid and the box body at the closing position. The electronic lock is connected to the control panel. An opening is made on the front of the box body to embed a transparent plate so that external personnel can observe the inside of the storage box.
[0016] The present invention has the following beneficial effects:
[0017] The medical slide storage device of this invention enables authorized personnel authentication and slide status recording through a control panel. A self-propelled inkjet printing mechanism prints borrowed information on a corresponding inkjet plate, making the information display more intuitive. Upon return, the information on the corresponding inkjet plate can be automatically erased by a designated wiping component, greatly improving the traceability and loss prevention capabilities of slide management.

[0043] Reference Figures 1-3 A preferred embodiment of the present invention provides a medical slide preservation device, comprising: a preservation box 1 that can be opened and closed; a control panel 2 connected to the outside of the preservation box 1 for automatically unlocking the preservation box 1 after inputting the information of the person retrieving the slide; a scissor-type lifting mechanism disposed inside the preservation box 1 and capable of being pulled out upward or pushed back downward under external force; multiple slide storage boxes 4 connected to the scissor-type lifting mechanism in a stacked manner; multiple sets of slide elastic clamping mechanisms arranged in a horizontal direction along the slide storage boxes 4; a self-propelled inkjet printing mechanism disposed inside the preservation box 1; and a cotton wiping component disposed in a horizontal direction along one side inside the preservation box 1. Each set of slide elastic clamping mechanisms is used to cooperate with the slide storage box 4 to elastically clamp a slide. Each slide elastic clamping mechanism includes an inkjet plate 51 located outside the slide storage box 4. The inkjet plate 51 is used to abut against the cotton wiping component during the process of clamping the slide in and out of the preservation box 1. The self-propelled inkjet printing mechanism is connected to the control panel 2. After startup, it automatically moves to the side of the slide to be retrieved selected by the system and connects to the inkjet plate 51 at the corresponding position. This pulls the slide elastic clamping mechanism to move away from the slide storage box 4 to the outside, releasing the clamped slide and causing the slide to be retrieved to pop up automatically. The self-propelled inkjet printing mechanism is also used to print lending information on the inkjet plate 51 during the outward movement of the slide elastic clamping mechanism. After the lending information is printed and the slide to be retrieved pops up automatically, the inkjet plate 51 is released and automatically returns to its original position. The slide elastic clamping mechanism is also used to retract into the slide storage box 4 under the action of elastic force after the slide is removed, so as to avoid the inkjet plate 51 from touching the cotton wiping component during the process of the slide storage box 4 entering and leaving the storage box 1.
[0044] The working process of the medical slide preservation device of the present invention is as follows: In the initial state, the preservation box 1 is in a closed state, which cannot be opened by unauthorized personnel; multiple slide storage boxes 4 are stacked one on top of the other inside the preservation box 1, and multiple medical slides to be used are placed side by side along the length of each slide storage box 4. The slides are pressed and secured by the slide storage box 4 and the corresponding slide elastic clamping mechanism. When authorized medical personnel need to use the slides, the operation process is as follows: The control panel 2 receives the use request. It should be noted that the control panel 2 integrates a PLC controller, human-machine interface, camera and fingerprint reader. Medical personnel need to authenticate their identity through facial recognition or fingerprint recognition, and the control panel 2 stores a database of authorized personnel. When the authentication is successful, the system will record the personnel, time and other information of this operation; then the slide selection operation is entered. The system can be set to randomly select a slide or determine a slide to be taken out according to preset rules.
[0045] Once the target slide is identified, control panel 2 activates the self-propelled inkjet printing mechanism. It first moves to the side of the slide to be retrieved, then connects to the corresponding inkjet plate 51, pulling it a short distance away from the slide storage box 4 to release the mounted slide, allowing it to automatically pop upwards for subsequent manual identification and retrieval. Simultaneously, as the self-propelled inkjet printing mechanism pulls the inkjet plate 51 outwards, it quickly prints lending information on the plate, such as the date and time of lending, and the borrower's name. This information printing is crucial for preventing slide loss. After printing, the self-propelled inkjet printing mechanism releases the inkjet plate 51 and automatically resets. Control panel 2 then unlocks storage box 1, allowing medical staff to manually store it. After the slide storage box 4 has been raised enough to provide sufficient operating space, the staff pinches the popped-up target slide, removes it, and then lowers the slide storage box 4 back down. Finally, storage box 1 is closed.
[0046] When returning the slides, authorized medical staff verify their identity and select the return mode through the control panel 2. After successful verification, the control panel 2 unlocks the storage box 1 and raises the slide storage box 4 to the target height to facilitate the placement of the slides. The medical staff locates the corresponding storage compartment for the slides using the information on the inkjet plate 51, and then pulls the slide elastic clamping mechanism outward to re-clamp the slides into the corresponding positions to re-secure the slides. At this time, because the slides occupy the space inside the compartment, the inkjet plate 51 is further outward than before the slides were returned.
[0047] A cotton wiping component is installed inside the storage box 1. When the slide storage box 4 is reset and stacked downwards, the front surface of the inkjet plate 51 will contact the cotton wiping component. The inkjet plate 51 corresponding to the returned slide is at the front. The inkjet plate 51 at the front will contact the cotton wiping component during the descent, and the printed information on it will be erased. However, the inkjet plate 51 of the elastic clamping mechanism of the slide that has not been returned is further back (i.e., closer to the inside of the slide storage box 4). During the descent, the inkjet plate 51 corresponding to the unreturned position will not contact the cotton wiping component, so the information printed on its surface is retained.
[0048] The medical slide storage device of this invention enables authorized personnel authentication and slide status recording through the control panel 2. A self-propelled inkjet printing mechanism prints borrowing information on the corresponding inkjet plate 51, making the information display more intuitive. After return, the information on the corresponding inkjet plate 51 can be automatically erased by a cotton wiping component, thereby greatly improving the traceability and loss prevention capabilities of slide management, avoiding confusion and loss due to record omissions. Furthermore, the slides cannot be opened by unauthorized personnel during storage, ensuring safe and reliable storage. Simultaneously, the multi-layer slide storage boxes 4 inside the storage box 1 adopt a stacked design, and with the cooperation of a scissor-lift mechanism, all slide storage boxes 4 can be unfolded, maximizing the storage of a larger quantity of slides within the limited box space. The upward lifting also provides sufficient operating space for manual slide handling, facilitating slide removal and archiving.
[0049] Optionally, such as Figure 6 and Figure 7 As shown, the slide storage box 4 has several partitions 91 arranged longitudinally on its first side. These partitions 91 are spaced apart laterally along the slide storage box 4, so that the gaps between adjacent partitions 91 form slots for holding the slides on the first side. The inner wall of the first side of the slide storage box 4 also has grooves 401 connecting to these slots, with the upper end of the grooves 401 extending to the top of the slide storage box 4 and the lower end of the grooves 401 higher than the bottom of the slides. The slide elastic clamping mechanism also includes a cooperating elastic clamping mechanism and an elastic support mechanism. The elastic clamping mechanism is connected to the second longitudinal side of the slide storage box 4 to engage with the corresponding slots on the first side of the slide storage box 4 to press and clamp the slides. The elastic support mechanism is located at the bottom of the slide storage box 4 to elastically support the slides. In this optional solution, the cooperative design of the elastic clamping mechanism and the elastic support mechanism provides stable positioning of the slides, and the elastic support mechanism also provides a certain buffering effect for the storage of the slides.
[0050] In this optional solution, such as Figure 7 and Figure 11-12As shown, the elastic clamping mechanism includes two first guide rods 52 arranged laterally and slidingly passing through the longitudinal second side wall of the slide storage box 4, an L-shaped clamping plate 53 with an L-shaped cross section and a vertical plate fixed to the inner ends of the two first guide rods 52, a first spring 54 mounted on each first guide rod 52 and with both ends limited between the L-shaped clamping plate 53 and the longitudinal second side wall, and a first limiting block 55 fixed to the outer end of each first guide rod 52. The two first limiting blocks 55 are simultaneously fixedly connected to the inkjet plate 51. The L-shaped clamping plate 53 cooperates with the corresponding slot to press down and clamp the slide. The elastic support mechanism includes a support base plate 57 located at the bottom of the slide to support the slide, two second guide rods 58 vertically arranged and slidingly passing through the bottom plate of the slide storage box 4, two second springs 59 fixed to the two second guide rods 58, and two second limiting blocks 61 fixed to the outer ends of the two second guide rods 58. The top ends of the two second guide rods 58 are respectively fixedly connected to the support base plate 57, and the two ends of the second springs 59 are limited between the support base plate 57 and the bottom plate of the slide storage box 4. Preferably, the surfaces of the spacer 91, the L-shaped clamping plate 53, and the support base plate 57 are all covered with rubber material.
[0051] When the slide is in the clamped state, the first side of the slide is limited by the gap between the two spacers 91, while the second side of the slide is clamped by the vertical plate of the L-shaped clamping plate 53. The inkjet plate 51 is connected to the corresponding L-shaped clamping plate 53 through the first limiting block 55 and the first guide rod 52. When the slide is inserted, the first spring 54 is in a pre-compressed state, so that the L-shaped clamping plate 53 applies a flexible clamping force to the slide. The support base plate 57 provided below the slide plays a supporting role for the slide. The support base plate 57 is elastically connected to the bottom of the slide storage box 4 through the second spring 59. When the slide is inserted, the second spring 59 is also in a compressed state.
[0052] Optionally, such as Figure 4 As shown, the cotton swab component includes a cotton swab mounting plate 81 fixed to one side of the outlet of the storage box 1, and a cotton swab fixed to the cotton swab mounting plate 81, with the cotton swab facing the side of the slide storage box 4. In this optional embodiment, the cotton swab mounting plate 81 is detachably mounted on the upper inner side of the storage box 1. Specifically, the cotton swab mounting plate 81 is detachably mounted using screws. The inkjet plate 51 is also printed with indelible positioning marks 62 for indicating the storage position of the slides. In this optional embodiment, the inkjet plate 51 is made of ABS material, and its surface is coated with a white high-gloss UV coating, so the ink on its surface can be easily wiped off. Positioning marks 62, such as A1, B1, etc., are provided on the surface of the inkjet plate 51. Preferably, a rotating shaft 63 is rotatably mounted on one side of the horizontal plate of the L-shaped clamping plate 53.
[0053] Optionally, such as Figure 4 and Figure 8As shown, the self-propelled inkjet printing mechanism includes a sliding mounting base 71, a sliding drive mechanism disposed inside the storage box 1 and connected to the sliding mounting base 71 to drive the sliding mounting base 71 to move laterally and vertically along the storage box 1, a miniature inkjet printer 72 and a miniature electric push rod 73 respectively fixed on the sliding mounting base 71, and a push plate 74 connected to the telescopic end of the miniature electric push rod 73 for connecting the inkjet plate 51. The sliding drive mechanism, the miniature inkjet printer 72 and the miniature electric push rod 73 are respectively connected to the control panel 2.
[0054] In this optional solution, such as Figure 4 As shown, the sliding drive mechanism includes a vertically arranged slide rail 751 that slides laterally along the storage box 1, a first lead screw 752 disposed in a vertical groove on the slide rail 751, a first servo motor 753 disposed at the bottom end of the slide rail 751 and connected to the first lead screw 752, a second lead screw 754 rotatably disposed within the storage box 1 along the lateral direction of the storage box 1, and a second servo motor 755 disposed within the storage box 1 and connected to the second lead screw 754. The first servo motor 753 and the second servo motor 755 are respectively connected to the control panel 2. A sliding mounting base 71 is threaded onto the outer circle of the first lead screw 752. The bottom end of the slide rail 751 is threaded onto the outer circle of the second lead screw 754.
[0055] During operation, once the target slide is determined, the control panel 2 controls the self-propelled inkjet printing mechanism to start working. The sliding drive mechanism can drive the sliding mounting base 71 to move in two dimensions. The sliding mounting base 71 drives the micro inkjet printer 72, the micro electric push rod 73, and the push plate 74 to move in front of the target slide. The specific working process is as follows:
[0056] Initially, the sliding mounting base 71 is located at the bottom corner of the inner side of the storage box 1. The micro electric push rod 73 is activated to drive the push plate 74 towards the inkjet plate 51 until the push plate 74 is positioned behind the inkjet plate 51. Then, the first servo motor 753 is activated to drive the first lead screw 752 to rotate. The rotation of the first lead screw 752 drives the sliding mounting base 71 to slide within the vertical groove of the slide rail 751 until the sliding mounting base 71 is positioned at the height of the target slide (the extension of the push plate 74 and the vertical movement of the sliding mounting base 71 can occur simultaneously). Then... The second servo motor 755 drives the second lead screw 754 to rotate. At this time, the slide rail 751, which is threadedly connected to the second lead screw 754, moves laterally until the entire slide rail 751 moves to the row where the target glass slide is located. When the sliding mounting base 71, carrying the micro inkjet printer 72, the micro electric push rod 73, and the push plate 74, arrives directly in front of the target glass slide, the push plate 74 is located behind the inkjet plate 51 corresponding to the target glass slide. Then, the micro electric push rod 73 is controlled to drive the push plate 74 forward, and the push plate 74 will hook the inkjet plate 51 and move it forward a short distance.
[0057] The movement of the inkjet plate 51 drives the L-shaped clamping plate 53 to move outward synchronously via the first guide rod 52. At this time, the vertical part of the L-shaped clamping plate 53 separates from the end of the target glass slide, thereby releasing the clamping limit on the glass slide. After the limit is released, the second spring 59 automatically resets and pushes the support base plate 57 and the target glass slide supported on it to bounce up a short distance, so that the glass slide protrudes slightly above the height of other glass slides, so as to facilitate subsequent manual identification and extraction. It should be added that after the glass slide pops out, its bottom end is higher than the bottom end of the groove 401. When the first spring 54 resets, the L-shaped clamping plate 53 pushes one end of the glass slide into the inside of the groove 401, and in this state, one end of the glass slide contacts the rotating shaft 63.
[0058] As the push plate 74 pulls the inkjet plate 51 closer to the micro inkjet printer 72, the micro inkjet printer 72 starts working. The micro inkjet printer 72 will quickly print information on the front surface of the corresponding inkjet plate 51, such as the date and time of borrowing the slide, the borrower's name, etc. During printing, the sliding mounting base 71 can be controlled to move slightly and smoothly, so that the print head can complete the printing of a line of text on the surface of the inkjet plate 51. Information printing is an important means of preventing slides from being lost.
[0059] After printing is completed, the miniature electric push rod 73 drives the push plate 74 to return to its original position. Under the elastic force of the first spring 54, the inkjet plate 51 is pulled backward. This inkjet plate 51 is further back than other inkjet plates 51 with slide positions (i.e., closer to the slide storage box 4). Then, the power unit drives the sliding mounting base 71 to return to the preset initial standby position (corner position) in the storage box 1.
[0060] Then, control panel 2 unlocks storage box 1. At this time, medical staff can manually open storage box 1. After the slide storage box 4 is raised to provide sufficient operating space, the medical staff pinches the target slide that has been lifted. During the process of pulling out the slide, the side of the slide will make rolling contact with the L-shaped clamping plate 53 and the pivot 63. The function of this design is to convert sliding friction into rolling friction, thereby significantly reducing the resistance when pulling out the slide and making the extraction action smooth and fluid. After removing the slide, the medical staff returns the slide storage box 4 to its original position and finally closes storage box 1.
[0061] When returning the slides, authorized medical staff verify their identity and select the return mode through the control panel 2. After successful verification, the control panel 2 controls the storage box 1 to open, and the slide storage box 4 is raised to the target height to facilitate the placement of the slides. The medical staff locates the corresponding storage compartment for the slide using the information on the inkjet plate 51, and then pulls the corresponding L-shaped clamping plate 53 outward by hand to provide space for the slide to be placed. After placing the slide in the compartment, the L-shaped clamping plate 53 is released. Under the elastic force of the first spring 54, the L-shaped clamping plate 53 automatically returns to its original position to re-clamp the slide. At this time, because the slide occupies the space in the compartment, the inkjet plate 51 is forward more than before the slide was returned.
[0062] A cotton swab mounting plate 81 is detachably installed on the upper inner side of the storage box 1. A cotton wipe is installed on the cotton swab mounting plate 81. When the slide storage box 4 is reset and stacked downwards, the front surface of the inkjet plate 51 will come into contact with the cotton wipe. The inkjet plate 51 corresponding to the returned slide is in front. The inkjet plate 51 in front will come into contact with the cotton wipe during the descent, and the printed information on it will be erased. However, the inkjet plate 51 in front of the grid of the unreturned slide is further back (i.e. closer to the slide storage box 4). During the descent, the inkjet plate 51 corresponding to the unreturned position will not come into contact with the cotton wipe, so the information printed on its surface is retained.
[0063] Optionally, such as Figures 4-6 As shown, the scissor lift mechanism includes two sets of scissor lift frames 31 disposed on both sides of the storage box 1. In this optional embodiment, the scissor lift frame 31 includes multiple sets of X-shaped rotating frames arranged side by side. Each X-shaped rotating frame includes two rotating rods, which are rotatably connected at their middle parts. The ends of the rotating rods are rotatably connected to the ends of adjacent rotating rods. Rotating shafts are rotatably installed at both ends of the slide storage box 4 and at both ends of the bottom of the inner wall of the storage box 1. Multiple rotating shafts are respectively connected to rotating shafts at multiple hinge points on the left side of the scissor lift frame 31. Each side of the slide storage box 4 is provided with a concave sliding groove 402, and each side of the bottom plate of the storage box 1 is also provided with a concave sliding groove 402, and the sliding grooves 402 extend along the longitudinal direction of the storage box 1. The scissor lift frame 31 is slidably connected to the slide grooves 402 of the slide storage box 4 and the storage box 1 via the first slider 32 and the second slider 33 respectively. The first slider 32 and the second slider 33 are each rotatably mounted with a second rotating shaft. The second rotating shafts are respectively connected to the rotating shafts at the corresponding hinge points on the right side of the scissor lift frame 31.
[0064] Furthermore, such as Figure 5 and Figure 9As shown, the scissor lift mechanism also includes a lifting and locking mechanism. This mechanism includes a positioning rod 341 horizontally arranged and slidingly passing through the second slider 33; a movable plate 342 fixed to the inner end of the positioning rod 341; a third guide rod 343 horizontally arranged and slidingly passing through the movable plate 342; a third limiting block 344 fixed to the inner end of the third guide rod 343; a third spring 345 fitted onto the outer circle of the third guide rod 343 and with both ends respectively limited between the third limiting block 344 and the movable plate 342; and a reset block 346. The outer end of the third guide rod 343 is fixedly connected to the second slider 33. A positioning hole 101 is also provided through the side wall of the storage box 1. The reset block 346 is inserted into the positioning hole 101 from the outside of the storage box 1. The positioning hole 101 is also used to allow the positioning rod 341 to be inserted during the lifting and lowering process of the scissor lift frame 31 to lock the scissor lift frame 31.
[0065] During operation, when medical staff lift the top slide storage box 4, the lever action of the scissor lift 31 causes all slide storage boxes 4 to unfold upwards at intervals, thus forming a uniform gap. If only a short slide retrieval is needed, it is not necessary to lift the top slide storage box 4 to the top limit position. For extended operations, the scissor lift 31 needs to be locked. Specifically, the top slide storage box 4 is lifted to the top limit position, at which point the positioning rod 341, under the action of the third spring 345, […]. When the end is inserted into the positioning hole 101, the scissor lift 31 and multiple slide storage boxes 1 can be locked at this height. At this time, medical staff can operate without worry. When it is necessary to lower it, first hold the top box with your hand, and then press the reset block 346 inward to the limited position, that is, the inner end of the reset block 346 is flush with the inner wall of the storage box 1. In this state, the inner end of the reset block 346 pushes the positioning rod 341 out of the positioning hole 101, thereby unlocking the second slider 33. Then the slide storage boxes 4 can be stacked and reset smoothly.
[0066] Optionally, such as Figure 4 As shown, the top slide storage box 4 is also connected to a pull plate 92, which is used to easily lift multiple slide storage boxes 4, and the pull plate 92 is L-shaped. Figure 6 and Figure 10 As shown, except for the bottommost slide storage box 4, each of the other slide storage boxes 4 has a vertically arranged movable rod 93 fixedly connected to its bottom corner, and a fourth limiting block 94 fixed to the bottom of the movable rod 93. Except for the topmost slide storage box 4, each of the other slide storage boxes 4 has a movable hole 403 extending inward from the top, and the movable rod 93 connected to the bottom of the upper slide storage box 4 is slidably installed in the corresponding movable hole 403 of the lower slide storage box 4, and the fourth limiting block 94 restricts the movable rod 93 from being pulled upward out of the movable hole 403.
[0067] During operation, medical staff hook their hands onto the top slide storage box 4 and lift it upwards. Since each slide storage box 4, except for the bottom one, has a movable rod 93 connected to its bottom, and each slide storage box 4, except for the top one, has a movable hole 403 at its corner, when the top box is lifted, its movable rod 93 slides upwards through the movable hole 403 of the second-layer box until the fourth limiting block 94 at the bottom of the movable rod 93 moves to the upper inner limit position of the movable hole 403 of the second-layer box. Then, continuing to lift upwards causes the second-layer box to be lifted as well. This process is repeated until all slide storage boxes 4 are lifted sequentially, increasing the gap between adjacent layers of slide storage boxes 4, facilitating the identification and retrieval of protruding target slides. It is also worth noting that the stacking arrangement increases the space utilization efficiency inside the storage box 1.
[0068] Optionally, such as Figure 1 As shown, the storage box 1 includes a hollow box body, a lid 11 hinged to one side of the box body for closing the top opening of the box body, a handle 12 fixed to the top of the lid 11, and an electronic lock 13 connected to the lid 11 and the box body at the closed position. The electronic lock 13 is connected to the control panel 2. The handle 12 is used to easily lift the storage box 1; the electronic lock 13 is an electromagnetic lock, a motor-driven electronic bolt lock, etc. An opening is made on the front of the box body to house a transparent plate 14, allowing external personnel to observe the interior of the storage box 1, mainly for observing the printed information on the inkjet plate 51. The control panel 2 is installed on the storage box 1. The control panel 2 uses a combination of a PLC controller and a human-machine interface, and is equipped with a camera and a fingerprint reader for identifying user information.

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.
