Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a suspended glass slide. Background Technology

[0002] Current technologies primarily employ the following two methods for the reaction between sample slides and reagents: (a) Inserting individual sample pieces into each reagent slot in sequence to allow the sample to react with the reagent is too slow and is only suitable for manual processing of a small number of sample pieces, not for batch processing.

[0003] (ii) Insert multiple sample slides into the basket, and then immerse the basket in the reagent bath. Let it move sequentially in each reagent bath to react with the reagents. Because there is a gap between the basket and the sample slides, a large amount of reagent will adhere to it and be carried to the next reagent bath, which can easily lead to cross-contamination. In addition, the sample slides inserted into the basket need to be taken out one by one, laid flat, and then sealed with glue before being inserted back into the basket. They cannot be directly scanned and viewed under a microscope. They need to be transferred to the microscope one by one. The operation is complicated and time-consuming. The sample slides need to be transferred multiple times, which is not suitable for automated equipment. Summary of the Invention

[0004] The present invention aims to at least improve one of the technical problems existing in the prior art. To this end, the present invention proposes a suspended glass slide.

[0005] The technical solution of the present invention is as follows: A drop-off slide plate is suitable for sample slides, the sample slides including a sample label portion and a sample cell portion, wherein the drop-off slide plate is used to batch hold the sample label portion of the sample slides to expose the sample cell portion, the drop-off slide plate comprising: The base plate has several grooves on its surface to increase the friction on the sample label and enhance stability. The first support rod and the second support rod are installed at both ends of the base plate; Multiple slide mounting assemblies are mounted on the base plate, forming multiple sample slide clamping areas between the first support rod and the second support rod for clamping the sample label portion of the sample slides, wherein each slide mounting assembly includes: The first stop block is installed at intervals on the base plate; The first stop bar is connected to the first stop block and has a gap with the base plate; The second stop bar is connected to the first stop bar and extends into the sample slide clamping area. The bottom of the second stop bar is flush with the base plate and is used to restrict and clamp the sample slide. The first pressure strip is installed on the side wall of the first stop strip away from the second stop strip; The second pressure strip is installed on the side wall of the second stop strip away from the first stop strip; The second stop is installed at the edge of the base plate and is used for top alignment when installing the sample slide.

[0006] In one possible technical solution, both the first and second stop bars are made of elastic material.

[0007] In one possible technical solution, the first pressure strip has a triangular cross-section, comprising: The pyramidal portion is connected to the first stop bar; A first protrusion is connected to the pyramidal portion away from the first stop bar, wherein the first protrusion has a first curved surface extending toward the sample slide clamping area, which facilitates snap-fitting and disassembly while preventing the sample slide from falling out during transfer.

[0008] In one possible technical solution, the second pressure strip has a rectangular cross-section, comprising: The prism portion is connected to the second stop bar; The second protrusion is connected to the prism portion away from the second stop bar, wherein the second protrusion has a second curved surface extending toward the sample slide clamping area, which facilitates snap-fit ​​disassembly while preventing the sample slide from falling out during transfer.

[0009] In one possible technical solution, the slide mounting assembly further includes: The third stop, installed on the base plate and located on the same axis as the first stop, is used to limit the unilateral displacement of the sample slide.

[0010] In one possible technical solution, the base plate located in each sample slide clamping area is further provided with an avoidance opening to facilitate the placement and removal of sample slides.

[0011] In one possible technical solution, the bottom plate located below each first stop bar is provided with a demolding through hole for demolding during plastic mold making, reducing demolding resistance and avoiding scratches or tears.

[0012] In one possible technical solution, each first block has a first magnetic recess on its surface for mounting, positioning and transporting the magnetic attraction.

[0013] In one possible technical solution, a second magnetic recess is further provided on the surface of the base plate away from the glass slide mounting assembly for installing positioning magnetic attachments.

[0014] In one possible technical solution, it further includes: Two circular support rods are installed on the side of the first and second support rods that are offset from the sample slide clamping area, which is beneficial for transporting and hooking away during fully automated processing.

[0015] According to the suspended slide plate of the present invention, the label part of the sample slide can be flexibly clamped in the slide plate, and the cell part of the sample slide is suspended below the slide plate. When inserted into the test solution tank, the cell part of the sample slide can be immersed in it, while the label part of the sample slide does not come into contact with the test solution, thereby reducing the stickiness of the frame reagent and minimizing cross-contamination.

[0016] This invention employs seamless positioning and fixing, and can hold multiple sample slides on a glass slide plate at once, while being convenient to pick up and put down, and having high work efficiency.

[0017] This invention can be used to move and transfer slides by hooking onto the two support rods, or by using a magnetic suction plate robotic arm to lift the slides by holding multiple magnetic suction plates. It can be mounted on a fully automated transport platform and can be moved back and forth between various workstations such as slide baking, reagent tank, slide sealing, loading and unloading, and microscope slide reading and scanning, which is convenient, fast and greatly improves work efficiency.

[0028] Example 1 like Figures 1 to 7 As shown, this embodiment provides a drop-off slide plate suitable for sample slides 10. The sample slide 10 includes a sample label portion 110 and a sample cell portion 120. The drop-off slide plate is used to batch hold the sample label portion 110 of the sample slide 10 to expose the sample cell portion 120. The drop-off slide plate includes: The base plate 1 has several grooves 101 on its surface to increase the friction on the sample label and enhance stability; The first support rod 2 and the second support rod 3 are installed at both ends of the base plate 1 to support the sample slides to be placed flat on the table and for positioning and guiding. Multiple slide mounting assemblies 4 are mounted on the base plate 1, forming multiple sample slide clamping areas between the first support rod 2 and the second support rod 3 for clamping the sample label portion of the sample slides, wherein each slide mounting assembly 4 includes: The first stop block 40 is installed at intervals on the base plate 1. In this embodiment, the first stop block 40 located at the beginning and end of the base plate is connected to the first support rod 2 and the second support rod 3, respectively. The first stop bar 41 is connected to the first stop block 40 and has a gap with the base plate 1; The second stop bar 42 is connected to the first stop bar 41 and extends into the sample slide clamping area. The bottom height of the second stop bar 42 is flush with the base plate 1, and is used to restrict and clamp the sample slide. The first pressure strip 43 is installed on the side wall of the first baffle 41 away from the second baffle 42 to prevent the sample slide 10 from falling out during the transfer process; The second pressure strip 44 is installed on the side wall of the second stop strip 42 away from the first stop strip 41; The second stop 45 is installed at the edge of the base plate 1 for top alignment during sample slide installation.

[0029] It should be noted that in this embodiment, the upper inner side of the second stop 45 has a downward inclined edge to facilitate the downward guidance of the glass slide. Alternatively, the upper part of the second stop 45 can protrude to form a groove with the base plate 1. After the sample slide is inserted, the protruding part of the upper part of the second stop 45 blocks the sample slide and prevents the sample slide from falling out.

[0030] It should be noted that in this embodiment, both the first stop bar 41 and the second stop bar 42 are made of elastic material. The first stop bar 41 can retract to make room for placing the sample slide 10, and can pop out and reset to push the sample slide 10 to the other side of the stop block to clamp multiple slides. The second stop bar 42 can retract to make room for placing the sample slide 10, and can pop out and reset to press the sample slide 10 onto the slide plate to prevent it from falling upwards.

[0031] It should be noted that, in this embodiment, the first pressure strip 43 has a triangular cross-section, comprising: The pyramidal portion 431 is connected to the first stop bar 41; The first protrusion 432 is connected to the pyramidal portion 431 away from the first stop bar 41, wherein the first protrusion 432 has a first curved surface extending into the sample slide clamping area, which facilitates snap-fit ​​disassembly while preventing the sample slide from falling out during transfer.

[0032] It should be noted that, in this embodiment, the second pressure strip 44 has a rectangular cross-section, comprising: Prismatic portion 441 is connected to the second stop bar 42; The second protrusion 442 is connected to the prism 441 away from the second stop 42, wherein the second protrusion 432 has a second curved surface extending into the sample slide clamping area, which facilitates snap-fit ​​disassembly while preventing the sample slide from falling out during transfer.

[0033] It should be noted that, in this embodiment, the slide mounting assembly 4 further includes: The third stop 46 is installed on the base plate 1 and is located on the same axis as the first stop 41, and is used to limit the unilateral displacement of the sample slide.

[0034] It should be noted that, in this embodiment, the base plate 1 located in each sample slide clamping area is provided with an avoidance opening 102 to facilitate the placement and removal of sample slides.

[0035] It should be noted that in this embodiment, the clearance opening 102 is arc-shaped, and the first stop block 40 is located on the arc trajectory of the clearance opening 102, which facilitates the picking and placing while ensuring that the sample slide has a large contact area with the base plate 1, thereby improving the clamping stability.

[0036] It should be noted that, in this embodiment, the base plate 1 located below each first stop bar 41 is provided with a mold-pulling through hole 103, which is used for mold pulling during plastic mold making, reducing demolding resistance and avoiding mold scratches or tears.

[0037] It should be noted that, in this embodiment, each first stop block 40 has a first magnetic recess 401 on its surface for mounting, positioning and transporting magnetic attraction.

[0038] It should be noted that, in this embodiment, a second magnetic recess 104 is provided on the surface of the base plate 1 away from the glass slide mounting assembly 4 for installing positioning magnetic attachments.

[0039] It should be noted that in this embodiment, the second magnetic recess 104 is located directly below the first stop 40 and is symmetrically arranged with the first magnetic recess 401, which facilitates positioning on both sides.

[0040] According to the suspended slide plate of the present invention, the label part of the sample slide can be flexibly clamped in the slide plate, and the cell part of the sample slide is suspended below the slide plate. When inserted into the test solution tank, the cell part of the sample slide can be immersed in it, while the label part of the sample slide does not come into contact with the test solution, thereby reducing the stickiness of the frame reagent and minimizing cross-contamination.

[0041] This invention employs seamless positioning and fixing, and can hold multiple sample slides on a glass slide plate at once, while being convenient to pick up and put down, and having high work efficiency.

[0042] Example 2 This embodiment further improves upon Embodiment 1, proposing a suspended glass slide plate, which also includes: Two circular support rods 5 are installed on the side of the first support rod 2 and the second support rod 3, which are offset from the sample slide clamping area, which is beneficial for transporting and hooking away during fully automated processing.

[0043] It should be noted that, in this embodiment, the first support rod 2 has a third magnetic recess 201 on both the upper and lower surfaces. The number of third magnetic recesses 201 on the upper surface is greater than the number of third magnetic recesses 201 on the lower surface. They are used in conjunction with the first magnetic recess 401 and the second magnetic recess 104 to pick up and transport the suspended glass slide.

[0044] It should be noted that in this embodiment, the upper and lower surfaces of the second support rod 3 are provided with fourth magnetic recesses 301, wherein the number of fourth magnetic recesses 301 on the upper surface is greater than the number of fourth magnetic recesses 301 on the lower surface, and they are used in conjunction with the first magnetic recesses 401 and the second magnetic recesses 104 for picking up and transporting suspended glass slides.

[0045] It should be noted that in this embodiment, the first support rod 2 and the second support rod 3 further include an arc portion 302, a beveled portion 303, and a prism portion 304. The arc portion 302 located in the gap between the first support rod 2 and the slide mounting assembly 4 is obtained by chamfering the first support rod 2, and the arc portion 302 located in the gap between the second support rod 3 and the slide mounting assembly 4 is obtained by chamfering the second support rod 3, facilitating the positioning of the suspended slide plate on the edge of the staining tank. The upper surfaces of the first support rod 2 and the second support rod 3 on one side offset from the slide mounting assembly 4 are beveled to form the beveled portion 303. Two beveled edges are formed on one side of the beveled portion 303 to form the prism portion 304. The beveled portions 303 and prism portions 304 formed by chamfering the first support rod 2 and the second support rod 3 on their respective rod bodies facilitate guiding and positioning, resulting in high matching efficiency.

[0046] The specific workflow of this invention is as follows: Step 1: Align the top edge of the sample label portion 110 of the sample slide 10 with the inner side of the second stop block 45 of the slide plate of the present invention; Step 2: Tilt the right side of the sample slide 10 downward and insert it into the second retainer 42, that is, the right side of the sample slide is below the second retainer 44; Step 3: Press the left side of the sample slide 10 downwards. At this time, the second stop bar 42 will retract to the right due to the pressure of the sample slide 10 pressing to the right. Under the action of the downward pressure, the left side of the sample slide 10 slides down along the arc edge of the adjacent first pressure bar 43. The elastic first stop bar 41 will retract to the left. At this time, the sample slide clamping area is opened up, and the sample slide enters the sample slide clamping area and flattens against the friction-increasing groove 101. The first stop bar 41 rebounds, causing the left side of the sample slide to press against the first stop block 40 and the first stop bar 41. The sample slide label is positioned and clamped in the sample slide clamping area. That is, the top of the sample slide is blocked by the second stop block 45, the left side is restricted by the first stop bar 41 and the first pressure bar 43, and the right side is restricted by the second stop bar 42 and the second pressure bar 44.

[0047] Step 4: After filling the sample slide holding areas of the slide plate of the present invention with sample slides, hold the round support rods 5 on both sides by hand or mechanically hook them, and place it into the reagent tank. The first support rod 2 and the second support rod 3 can be used to support the sides of the reagent tank. The cell portion of the sample slide is immersed in the reagent liquid, and the label portion of the sample slide is supported on the reagent tank.

[0048] Step 5: After the sample slide has been immersed in the reagent bath for the required reaction time, hook the round support rods 5 on both sides to lift and move the slide plate of the present invention to the next reagent bath reaction or other work positions.

[0049] Step 6: By hooking the round support rods 5 on both sides, the slide of the present invention can be pulled to the sealing platform for direct dispensing and sealing. Alternatively, the slide of the present invention can be pushed in with the hook or magnetically attracted and then moved to the microscope scanning stage for scanning and photography. In other words, the slide of the present invention can be moved by supporting the round support rods 5 on both sides, or it can be moved on the platform by pulling the round support rods 5 on both sides with the hook, or it can be moved by magnetic attraction.

[0050] According to the suspended slide plate of the present invention, the label part of the sample slide can be flexibly clamped in the slide plate, and the cell part of the sample slide is suspended below the slide plate. When inserted into the test solution tank, the cell part of the sample slide can be immersed in it, while the label part of the sample slide does not come into contact with the test solution, thereby reducing the stickiness of the frame reagent and minimizing cross-contamination.

[0051] This invention employs seamless positioning and fixing, and can hold multiple sample slides on a glass slide plate at once, while being convenient to pick up and put down, and having high work efficiency.

[0052] This invention can be lifted horizontally by multiple magnetic attachments distributed on the base plate and support rod, and can be mounted on a fully automated transport platform to transfer back and forth between the reagent tank and the microscope slide for scanning, which is convenient, fast and greatly improves work efficiency.
