Abstract
Description
Technical Field
[0001] This utility model relates to the field of isolation box technology, and in particular to a reagent dropper isolation box. Background Technology
[0002] Reagent dropper isolation boxes are mainly used in experimental operations in fields such as cytology, genetics, and pathology. In particular, when performing chromosome karyotype analysis, the isolation boxes can effectively isolate samples, prevent cross-contamination, and maintain sample humidity and stability.
[0003] Traditional isolation boxes typically involve placing stained glass slides directly onto a placement component inside the box. Some slides are cleaned with distilled water during the experiment. When the slides enter the isolation box and come into direct contact with the placement component, distilled water can accumulate between the slides and the component, diluting the reagents on the slides. This can also cause the distilled water to flow between different slides, leading to cross-contamination and interfering with the experimental results. Utility Model Content
[0004] The purpose of this invention is to solve the problem that when a dropper enters the isolation box and comes into direct contact with the placement component inside the isolation box, distilled water will accumulate between the dropper and the placement component, causing dilution of the reagent on the dropper and potentially causing cross-contamination between different droppers, thus interfering with experimental results. The proposed reagent dropper isolation box addresses this issue.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a reagent dropper isolation box, including a box body, a box cover provided at the top of the box body, the size of the box cover being adapted to the size of the box body, and an auxiliary device provided inside the box body, the auxiliary device including a groove plate, the groove plate being fixed inside the box body.
[0006] The effect achieved by the above components is as follows: when using the isolation box, lift the lid upwards to remove the lid, then place the dropper on the slot plate inside the box, and close the lid to isolate the dropper inside the box.
[0007] Preferably, the groove plate and the box body form a certain angle. Several partitions are fixedly connected to the outer surface of the groove plate, and the partitions divide the top of the groove plate into several areas of equal area. Several through holes are opened on the outer surface of the groove plate, and the through holes penetrate the bottom of the inner wall of the groove plate. A protruding rod is fixedly connected to one side of the partition plate. The protruding rod is an inclined L-shaped rod. Several drop grooves are opened on the outer surface of the groove plate.
[0008] The effect achieved by the above components is as follows: By setting the protruding rods, when placing the dropper, a single dropper is placed between the two partitions on the outer surface of the tray plate, so that the bottom sides of the dropper rest on the protruding rods on the outer surface of the two partitions, creating a certain gap between the dropper and the partition surface. After the dropper is placed above the tray plate, due to the tilt of the tray plate, the distilled water remaining on the surface of the dropper will drip onto the outer surface of the tray plate and flow down the tray plate in the direction of falling into the groove. At the same time, during the flow, it can enter the box inside below the tray plate through the through holes on the outer surface of the tray plate, preventing the distilled water from accumulating at the contact point between the dropper and the tray plate, thus preventing the dilution of the reagent on the dropper. The partitions separate the areas on the tray plate, allowing the distilled water from different droppers to flow out through the groove on the outer surface of the tray plate, preventing cross-contamination and improving the practicality of the isolation box during use.
[0009] Preferably, the top edge of the partition is arc-shaped.
[0010] The effect achieved by the above components is that by setting the top edge of the partition to be arc-shaped, when the operator places the dropper on the surface of the slot plate, the dropper is less likely to cause friction and scratches when it comes into contact with the top of the partition.
[0011] Preferably, a plurality of rubber limiting strips are fixedly connected to the outer surface of the trough plate, and the limiting strips are located on the side of the outer surface of the trough plate near the drop trough.
[0012] The effect achieved by the above components is that after the dropper is placed on the protruding rod on the outer surface of the slot plate, one part of the surface of the dropper will rest on the top of the limiting strip. The rubber limiting strip can prevent the dropper from sliding and shifting on the slot plate as much as possible.
[0013] Preferably, the end of the trough plate away from the drop trough is provided with a plurality of auxiliary grooves, and the internal shape of the auxiliary grooves is semi-circular.
[0014] The effect achieved by the above-mentioned components is that when removing the dropper from the outer surface of the slot plate, a finger can be inserted into the auxiliary slot at one end of the slot plate to facilitate contact with the surface of the dropper and remove it.
[0015] Preferably, a deflection device is provided at one end of the box body. The deflection device includes a rotating shaft. A baffle is fixedly connected to the outer surface of the rotating shaft. A groove is opened at one end of the box body. The rotating shaft is located inside the groove. Both ends of the rotating shaft are rotatably connected to the inner walls of the groove. A coil spring is provided at one end of the rotating shaft. Both ends of the coil spring are fixedly connected to one side of the rotating shaft and one side of the outer surface of the box body, respectively.
[0016] The effect achieved by the above-mentioned components is as follows: By setting up a baffle, when using the isolation box, when the dropper is placed on the surface of the slot plate or removed from the surface of the slot plate, the contact between the hand and the top of the baffle can push the baffle to rotate outward at a certain angle inside the groove through the rotating shaft, causing the coil spring to deform. At this time, it is convenient to place the finger under the dropper at one end of the slot plate and remove the dropper. After the hand moves away from the top of the baffle, the coil spring returns to its original state, which will drive the rotating shaft and the baffle to rotate back to the original position and close one side of the box. By setting a baffle that can rotate at a small angle, it is convenient for the operator to remove the dropper from the inside of the box, improving the flexibility of the isolation box when using it.
[0017] Preferably, sealing strips are fixedly connected to both sides of the baffle, and the sealing strips are made of rubber.
[0018] The effect achieved by the above components is that by setting a rubber sealing strip, the contact points between the outer surface of the baffle and the inner walls of the box can be further sealed, thereby improving the sealing effect after the box is closed.
[0019] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0020] In this invention, by setting an auxiliary device, when placing the dropper, the dropper is placed between two partitions on the outer surface of the trough plate and rests on the protruding rod, so that distilled water will not accumulate at the contact point between the dropper and the trough plate, causing dilution of the reagent on the dropper. The partitions separate the areas on the trough plate, so that the distilled water from different droppers flows out through the drop groove on the outer surface of the trough plate, preventing cross-contamination and improving the practicality of the isolation box.

[0027] Example 1, such as Figure 1-3 As shown, the reagent dropper isolation box includes a box body 1, with a lid 4 at the top of the box body 1. The size of the lid 4 is adapted to the size of the box body 1. An auxiliary device 2 is provided inside the box body 1. The auxiliary device 2 includes a slot plate 21, which is fixed inside the box body 1. When using the isolation box, the lid 4 is pulled up and removed. Then, the dropper is placed on the slot plate 21 inside the box body 1, and the lid 4 is closed to isolate the dropper inside the box body 1.
[0028] Reference Figure 1-4 As shown in this embodiment: the slot plate 21 and the box body 1 form a certain angle. Several partitions 22 are fixedly connected to the outer surface of the slot plate 21. The partitions 22 divide the top of the slot plate 21 into several areas of equal area. Several through holes 23 are opened on the outer surface of the slot plate 21, and the through holes 23 penetrate the bottom of the inner wall of the slot plate 21. A protruding rod 24 is fixedly connected to one side of the partition 22. The protruding rod 24 is an inclined L-shaped rod. Several drop grooves 25 are opened on the outer surface of the slot plate 21. By setting the protruding rod 24, when placing the dropper, a single dropper is placed between two partitions 22 on the outer surface of the slot plate 21, so that the bottom ends of the dropper rest on the protruding rods 24 on the outer surface of the two partitions 22, so that the dropper and the partitions are aligned. There is a certain gap between the surfaces of the two plates. After the dropper is placed above the tray plate 21, due to the inclination of the tray plate 21, the distilled water remaining on the surface of the dropper will drip onto the outer surface of the tray plate 21 and flow down the tray 25 along the surface of the tray plate 21. At the same time, during the flow, it can enter the box 1 below the tray plate 21 through the through hole 23 on the outer surface of the tray plate 21, so that the distilled water will not accumulate at the contact point between the dropper and the tray plate 21, causing the reagent on the dropper to be diluted. The area on the tray plate 21 is separated by the partition plate 22, so that the distilled water flowing out from different droppers flows out through the drop 25 on the outer surface of the tray plate 21, preventing cross-contamination and improving the practicality of the isolation box.
[0029] Reference Figure 2-4As shown in this embodiment: the top edge of the partition 22 is arc-shaped. By setting the top edge of the partition 22 to be arc-shaped, when the operator places the dropper on the surface of the slot plate 21, the dropper is less likely to cause friction and scratches when it comes into contact with the top of the partition 22. Several rubber limiting strips 26 are fixedly connected to the outer surface of the slot plate 21. The limiting strips 26 are located on the side of the outer surface of the slot plate 21 near the drop trough 25. After the dropper is placed on the protrusion 24 on the outer surface of the slot plate 21, one part of the surface of the dropper will rest on the top of the limiting strip 26. The rubber limiting strips 26 can prevent the dropper from sliding and shifting on the slot plate 21 as much as possible.
[0030] Reference Figure 2-4 As shown in this embodiment: a plurality of auxiliary grooves 27 are provided at one end of the groove plate 21 away from the drop groove 25. The internal shape of the auxiliary grooves 27 is semi-circular. When the droplet is removed from the outer surface of the groove plate 21, a finger can be inserted into the auxiliary groove 27 at one end of the groove plate 21 to facilitate contact with the surface of the droplet and remove the droplet.
[0031] Reference Figure 1-3 As shown in this embodiment: a deflection device 3 is provided at one end of the box body 1. The deflection device 3 includes a rotating shaft 32. A baffle 34 is fixedly connected to the outer surface of the rotating shaft 32. A groove 31 is opened at one end of the box body 1. The rotating shaft 32 is located inside the groove 31. The two ends of the rotating shaft 32 are rotatably connected to the two sides of the inner wall of the groove 31. A coil spring 33 is provided at one end of the rotating shaft 32. The two ends of the coil spring 33 are fixedly connected to one side of the rotating shaft 32 and one side of the outer surface of the box body 1, respectively. By setting the baffle 34, when using the isolation box, when the dropper is placed on the surface of the groove plate 21 or when the dropper is removed from the surface of the groove plate 21, the hand can contact the top of the baffle 34 to push the baffle 34 to rotate outward through the rotating shaft 32 inside the groove 31. The spring 33 is deformed at a fixed angle, allowing a finger to be easily placed under the dropper at one end of the slot plate 21. After the dropper is removed and the hand is away from the top of the baffle 34, the spring 33 returns to its original position, causing the rotating shaft 32 and the baffle 34 to rotate back to their original position and close one side of the box 1. The baffle 34, which can rotate at a small angle, makes it easier for operators to remove the dropper from inside the box 1, improving the flexibility of the isolation box during use. Sealing strips 35 are fixedly connected to both sides of the baffle 34. The sealing strips 35 are made of rubber. By setting the rubber sealing strips 35, the contact points between the outer surface of the baffle 34 and the inner walls of the box 1 can be further sealed, improving the sealing effect after the box 1 is closed.
[0032] Working principle: When using the isolation box, lift the lid 4 upwards to remove it. When placing the dropper, place a single dropper between the two partitions 22 on the outer surface of the trough plate 21, so that the bottom sides of the dropper rest on the protruding rods 24 on the outer surface of the two partitions 22, creating a certain gap between the dropper and the surface of the partitions 22. After the dropper is placed above the trough plate 21, due to the inclination of the trough plate 21, the distilled water remaining on the surface of the dropper will drip onto the outer surface of the trough plate 21 and flow down the trough plate 21 into the trough 25. During the flow, the droplet can enter the box 1 below the trough plate 21 through the through hole 23 on the outer surface of the trough plate 21. The box cover 4 is closed to isolate the droplet inside the box 1. When taking out the droplet, lift the box cover 4 upwards to remove the box cover 4. You can contact the top of the baffle 34 with your hand and push the baffle 34 to rotate outwards through the rotating shaft 32 in the groove 31 at a certain angle, causing the coil spring 33 to deform. Then insert your finger into the auxiliary groove 27 at one end of the trough plate 21 to make contact with the surface of the droplet and take the droplet out of the surface of the trough plate 21.
