Description

Technical Field

[0001] This invention relates to the field of medical testing equipment, and in particular to a slide holder for loading biological sample slides. Background Technology

[0002] Currently, slide holders are commonly used tools in experiments in cell biology, biology, and agronomy. They are used to store or transport multiple slides at the same time and to prevent contact between adjacent slides, thus protecting the slides.

[0003] Currently, during the dyeing process, the slide holder containing the slides needs to be placed into the restoration tank, immersed in the restoration solution or other liquids, and then heated to complete the restoration process. The common method for positioning the slide holder in the restoration tank is to install insert blocks on both sides of the slide holder and insert them into the insert slots at the opening of the restoration tank. Both the insert blocks and the insert slots are vertical.

[0004] Regarding the aforementioned technologies, in actual use, due to the principle of thermal expansion and contraction, a certain deformation gap is required between the insertion block and the insertion slot. However, this deformation gap is difficult to control. If the gap is too large, the horizontal position of the slide holder in the repair cylinder will be uncertain, which is not conducive to automated grasping. If the gap is too small, the slide holder will undergo horizontal thermal expansion deformation, making the slides placed in the slide holder unstable. Summary of the Invention

[0005] In order to automatically absorb the expansion of the slide holder in the horizontal direction and improve the stability and horizontal positioning accuracy of the slide holder in the repair tank, this application provides a slide holder for loading biological sample slides.

[0006] This application provides a slide holder for loading biological sample slides, which adopts the following technical solution:

[0007] A slide holder for loading biological sample slides includes a frame and a pair of insert blocks. The two insert blocks are respectively disposed on both sides of the frame and are used to insert into insert slots pre-set in the inner sidewall of a repair tank. An inclined surface is provided on the side of the insert block away from the frame, and the inclined surface slopes downward from the top of the insert block toward the frame. The groove wall of the insert slot is adapted to the inclined surface.

[0008] By adopting the above technical solution, during use, the frame is placed into the repair cylinder, and the plug-in block is inserted into the plug-in slot. During the process, the frame can be accurately positioned by the guiding action of the inclined surface and the slot wall. When the frame expands due to heat during the heating repair process, the frame can be moved upward as a whole by the guiding action of the inclined surface and the slot wall. During the process, the central axis of the frame in the vertical direction remains on the same straight line and will not move to the sides. This achieves automatic absorption of the expansion of the slide frame in the horizontal direction, while greatly improving the stability of the slide frame in the repair cylinder and the accuracy of its horizontal position, without affecting the automated grasping.

[0009] Preferably, handles are installed on both sides of the top of the frame, the handles are vertically extended, and the two plug-in blocks are respectively installed on the side of the two handles that are far apart from each other.

[0010] By adopting the above technical solution, since the slide holder is small in size, it is easy for operators to pick up and put down the slide holder by simply grasping the handle with two fingers of one hand, thus improving the ease of use.

[0011] Preferably, the end of the handle away from the frame has a through hole.

[0012] By adopting the above technical solution, when the operator grips the handle with two fingers, the flesh of the fingers will be inserted into the through hole, thereby reducing the possibility of the slide holder slipping off the fingers during the gripping process; in addition, the through hole also facilitates the gripping of the robotic arm.

[0013] Preferably, the frame includes a pair of side plates, two sets of connecting rods, two sets of limiting rods, and a bottom support. The two side plates are arranged opposite to each other. The two sets of connecting rods are each arranged between the two side plates, with both ends of the connecting rods connected to the two side plates respectively. The two sets of connecting rods are arranged opposite to each other and are respectively arranged on both sides of the side plates in the horizontal direction. The two sets of limiting rods are respectively installed on the opposite side of the two sets of connecting rods. The two sets of limiting rods are arranged one-to-one with each other. The limiting rods are arranged vertically. Each limiting rod in the same set is spaced apart along the length direction of the connecting rod. A limiting groove for inserting a glass slide is formed between adjacent limiting rods. The two ends of the bottom support are respectively connected to the bottom ends of the two side plates. The bottom support has a locking groove for the end of the glass slide to be inserted.

[0014] By adopting the above technical solution, the two sides of the slide are respectively inserted into the corresponding two limiting grooves. Then, by releasing the slide, the slide will slide spontaneously until the end of the slide is locked into the locking groove on the bottom support, thus completing the placement of the slide. This placement is highly efficient. The bottom of the slide holder only uses one bottom support to limit the slides, which not only reduces the overall cost of the slide holder, but also reduces the amount of repair fluid left in the slide holder.

[0015] Preferably, each group of connecting rods is provided with a pair, and the two connecting rods in the same group are spaced apart in the height direction of the limiting rod, and the limiting groove is in communication with the gap between the two connecting rods in the same group.

[0016] By adopting the above technical solution, only two connecting rods are set for each group, which not only reduces the overall cost, but also allows the liquid to drain out of the slide holder more quickly when the slide holder is removed from the container.

[0017] Preferably, the connecting rod in the same group that is close to the bottom support is provided with a guide surface, which is located on the side of the gap between two connecting rods in the same group.

[0018] By adopting the above technical solution, when the slide holder is removed from the container, the guiding effect of the guide surface can reduce liquid residue and facilitate liquid flow.

[0019] Preferably, the end of the limiting rod away from the bottom support and both sides of the limiting rod in the arrangement direction are provided with guide surfaces.

[0020] By adopting the above technical solution, the setting of the guide surface makes the glass slide fit into the limiting groove more smoothly.

[0021] Preferably, the corners of the plug-in blocks are all arc-shaped.

[0022] By adopting the above technical solution, the shape of the plug block can be made smoother, improving the smoothness of various operations.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. During the heating and repair process, when the frame expands due to heat, it can still be guided by the inclined surface and the groove wall of the insertion slot, allowing the frame to move upward as a whole. During the process, the central axis of the frame in the vertical direction remains on the same straight line and will not move to the sides, which greatly improves the stability of the slide holder in the repair cylinder and the accuracy of its position in the horizontal direction, without affecting the automated gripping.

[0025] 2. The slide holder can be grasped directly with two fingers of one hand, improving ease of use;

[0026] 3. The two sides of the slide are respectively inserted into the corresponding limiting grooves. Then, by releasing the slide, the slide will slide spontaneously until the end of the slide is locked into the locking groove on the bottom support, thus completing the placement of the slide. This placement method is highly efficient. The bottom of the slide holder only uses one bottom support to limit the position of each slide, which not only reduces the overall cost of the slide holder, but also reduces the amount of restoration fluid left in the slide holder.

[0032] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0033] The inner cavity shape of the repair cylinder 101 described in this application embodiment is adapted to the outer shape of the slide holder. The repair cylinder 101 has insertion grooves 102 at both ends of the inner side wall of the opening in the length direction.

[0034] This application discloses a slide holder for loading biological sample slides. (See also...) Figure 1The slide holder includes a frame body 1 and a pair of plug-in blocks 2. The frame body 1 includes a pair of side plates 11 and two sets of connecting rods 12. The two side plates 11 are arranged vertically opposite each other. Each set of connecting rods 12 has two rods. Both sets of connecting rods 12 are arranged between the two side plates 11. The two sets of connecting rods 12 are respectively arranged on both sides of the side plates 11 in the width direction. The two connecting rods 12 in the same set are spaced apart in the vertical direction. The two ends of the connecting rods 12 are respectively fixedly installed on the two side plates 11. The connecting rods 12 extend horizontally in the arrangement direction of the two side plates 11. Each side plate 11 has a through hole 111.

[0035] Reference Figure 2 and Figure 3 The top of each of the two side plates 11 is integrally formed with a handle 13, which extends vertically. Two plug-in blocks 2 are integrally formed on the side of the two handles 13 that are far apart from each other, and the plug-in blocks 2 are located at the end of the handle 13 that is close to the side plate 11. A through hole 131 is opened on the end of the handle 13 that is far away from the side plate 11. The plug-in block 2 is inserted into the plug-in groove 102 located on the inner side wall of the repair cylinder 101. The side of the plug-in block 2 that is far away from the handle 13 is provided with an inclined surface 21. The inclined surface 21 is inclined downward from the top of the plug-in block 2 towards the handle 13. The groove wall of the plug-in groove 102 is adapted to the inclined surface 21. The corners of the plug-in block 2 are all arc-shaped.

[0036] Thus, the operator can use two fingers of one hand to grasp the handle 13 and place the slide holder into the repair cylinder 101. After releasing the handle, the slide holder can be accurately positioned by the guiding action of the inclined surface 21 and the groove wall of the insertion slot 102. When the frame 1 expands due to heat, the frame 1 can still be moved upward as a whole by the guiding action of the inclined surface 21 and the groove wall of the insertion slot 102. During the process, the central axis of the frame 1 in the vertical direction is always on the same straight line and will not move to the sides.

[0037] Reference Figure 1The frame 1 also includes two sets of limiting rods 14 and a bottom support 15. The two sets of limiting rods 14 are respectively fixedly installed on opposite sides between the two sets of connecting rods 12. There are multiple limiting rods 14 in the same set. Each limiting rod 14 in the same set is equally spaced along the length direction of the connecting rod 12. A limiting groove 141 is formed between two adjacent limiting rods 14. The limiting grooves 141 on both sides are set one-to-one. An insertion position is formed between the two corresponding limiting grooves 141 in each set. Each limiting groove 141 is connected to the same set of limiting rods 141. The two connecting rods 12 are connected by a gap; the bottom support 15 extends along the length of the two side plates 11, and the two opposite ends of the bottom support 15 are respectively fixedly installed at the bottom middle position of the two side plates 11. The bottom support 15 has a number of locking slots 151 on the side facing the insertion position, and the number of locking slots 151 are set one by one with each insertion position; so that the slide can be inserted from the top of the insertion position from top to bottom until the bottom end of the slide is locked into the locking slot 151, so that the slide can be stably placed in the slide holder.

[0038] One of the two connecting rods 12 in the same group, which is closer to the bottom support 15, has a guide surface 121. The guide surface 121 is located on the side of the gap between the two connecting rods 12 in the same group. The guide surface 121 is inclined downward from the side closer to the limiting rod 14 toward the side away from the limiting rod 14, thereby improving the fluid flow.

[0039] The end of the limiting rod 14 away from the bottom support 15 and both sides of the arrangement direction of each limiting rod 14 are provided with guide surfaces 142. The two corresponding guide surfaces 142 in each limiting groove 141 extend from the end face of the limiting rod 14 away from the bottom support 15 toward each other, thereby improving the smoothness of the glass slide being inserted into the limiting groove 141.

[0040] The implementation principle of a slide holder for loading biological sample slides in this application embodiment is as follows: the two sides of the slide are respectively inserted into two corresponding limiting grooves 141. Then, by releasing the hand, the slide can be slid spontaneously by the limiting action of the two adjacent limiting rods 14 until the end of the slide is stuck into the locking groove 151 on the bottom support 15, thereby completing the placement of the slide; then, the handle 13 is grasped by two fingers of one hand and placed into the repair cylinder 101 until the insertion block 2 is inserted into the insertion groove 102. The inclined surface 21 of the insertion block 2 is adapted to the groove wall of the insertion groove 102, so that during the heating repair process, the frame 1 expands due to heat. Through the guiding action of the inclined surface 21 and the groove wall of the insertion groove 102, the frame 1 can move upward as a whole. During the process, the central axis of the frame 1 in the vertical direction is always on the same straight line.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
