Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sterilization boxes, in particular to a pipette tip sterilization device. Background Art
[0002] In the process of microbiological testing and cell culture experiments, sterile pipette tips are often needed. Sterile pipette tips are expensive and cannot guarantee sterility once opened. Generally, laboratories purchase ordinary pipette tips on their own and sterilize them for use.
[0003] At present, moist heat sterilization is mostly used for sterilization of pipette tips, and the sterilization effect and preservation requirements need to be guaranteed. At present, laboratory pipette tips are usually sterilized by breathing bag packaging sterilization and ordinary plastic sterilization boxes for storing pipette tips for moist heat sterilization. During the breathing bag packaging sterilization, the tip of the pipette tip suction nozzle is easy to puncture the breathing bag and cause contamination. During the sterilization process of the sterilization box, there are no corresponding air holes, resulting in insufficient heat penetration effect, which is prone to incomplete sterilization. In addition, it is difficult to discharge the steam after entering, which is not conducive to preservation. Therefore, in response to the above problems, we propose a new type of pipette tip sterilization device. Utility Model Content

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.
[0024] See also Figure 1-Figure 5 As shown, the utility model provides a technical solution: a pipette tip sterilization device, comprising a circular box 1, a plurality of first water drainage and steam exhaust holes 13 are opened at the bottom of the circular box 1 near the rear side, a top cover 4 is arranged on the top of the circular box 1, a second rotating plate 5 is rotatably connected to the top of the top cover 4, a second damping rotating shaft 51 is installed at the top center of the second rotating plate 5, a third rotating plate 6 is fixedly connected to the outer surface of the second damping rotating shaft 51, a plurality of first sterilization air holes 53 are opened at the top of the second rotating plate 5 near the left side, and a plurality of second sterilization air holes 62 are opened at the top of the third rotating plate 6 near the left side.
[0025] like Figure 1-Figure 3As shown, a first opening 52 is provided at a top of the second rotating plate 5 near the left rear side, and a second opening 61 is provided at a top of the third rotating plate 6 near the left rear side. When the second rotating plate 5 is rotated so that the first opening 52 and the second opening 61 on the third rotating plate 6 coincide with each other, the pipette tips at the corresponding positions can be directly taken out, and when the second rotating plate 5 and the third rotating plate 6 are rotated at the same time, the pipette tips at other positions can be taken out. There are fewer auxiliary actions in the process, and taking the pipette tips from the opening can minimize the exposure of other unused pipette tips to the air, thereby reducing the risk of microbial contamination.
[0026] like Figure 1-Figure 3 and Figure 5 As shown, the outer surface of the top cover 4 is symmetrically fixedly connected with a buckle 31, and the outer surface of the circular box 1 is symmetrically fixedly connected with a block 3. The buckle 31 and the block 3 are snap-fitted together, and the buckle 31 and the block 3 cooperate with each other to facilitate the disassembly and assembly of the top cover 4. After the top cover 4 is removed, the pipette tip can be conveniently installed for sterilization.
[0027] like Figure 1-Figure 3 and Figure 5 As shown, the front and rear outer surfaces of the buckle 31 are fixedly connected near the bottom with a limiting block 32, and the limiting block 32 fits the outer surface of the block 3. After the buckle 31 and the block 3 are engaged and connected, the limiting block 32 will rest against the front and rear sides of the block 3, thereby improving the connection stability between the buckle 31 and the block 3.
[0028] like Figure 2-Figure 4 As shown, the top of the circular box 1 is symmetrically provided with sockets 14, and the bottom of the top cover 4 is symmetrically fixedly connected with plug posts 41, and the plug posts 41 are plugged into the sockets 14. When installing the top cover 4, the plug posts 41 are inserted into the sockets 14 at the top of the circular box 1 to play a positioning role, thereby facilitating the precise docking of the buckle 31 and the block 3, so that the top cover 4 and the circular box 1 can be well snapped and sealed to ensure the sterilization effect.
[0029] like Figure 2 and Figure 4 As shown, a card plate 11 is fixedly connected between the inner walls of the circular box 1 near the upper position, and a plurality of embedding holes 12 are opened on the top of the card plate 11. The card plate 11 cooperates with the embedding holes 12 to support the pipette tip, and the tip of the pipette tip is in a suspended state, thereby reducing microbial contamination, and the pipette tip can be sterilized or stored by wet heat.
[0030] like Figure 4As shown, a first damping shaft 2 is installed at the bottom center of the circular box 1, and a first rotating plate 21 is connected to the outer surface of the first damping shaft 2. A plurality of second drainage and steam exhaust holes 22 are provided at the bottom of the first rotating plate 21 near the front side. After the first rotating plate 21 is rotated so that the second drainage and steam exhaust holes 22 correspond to the first drainage and steam exhaust holes 13 at the bottom of the circular box 1, steam can smoothly enter the circular box 1 for sterilization, and the heat penetration effect is better. The condensed water generated by the steam is conveniently discharged from the first drainage and steam exhaust holes 13 and the second drainage and steam exhaust holes 22 to ensure the dryness of the box and the pipette tip.
[0031] The method of using the device and the working principle: when the device needs to be used to sterilize the pipette tip, first open the top cover 4, insert the pipette tip into the embedded hole 12 on the card plate 11, and then snap the top cover 4 and the round box 1 together, and then rotate the first rotating plate 21, the second rotating plate 5 and the third rotating plate 6 so that the first drainage and steam exhaust hole 13 and the second drainage and steam exhaust hole 22 coincide, and the first sterilization air hole 53 and the second sterilization air hole 62 coincide, at this time, after wet heat sterilization, the steam can pass smoothly through the round box 1, and the heat penetration effect is improved. The effect is better, ensuring the sterilization effect; after the sterilization is completed, the condensed water generated by the steam is conveniently discharged from the first drainage and steam exhaust holes 13 and the second drainage and steam exhaust holes 22 to ensure the dryness of the box and the pipette tip; then the first rotating plate 21, the second rotating plate 5 and the third rotating plate 6 are rotated so that the first drainage and steam exhaust holes 13 and the second drainage and steam exhaust holes 22 are staggered, and the first sterilization air holes 53 and the second sterilization air holes 62 are staggered and the circular box 1 is in a closed state to avoid biological contamination, that is, the sterilized pipette tips can be stored. When the sterilized pipette tips need to be taken, the second rotating plate 5 is rotated so that the first opening 52 and the second opening 61 on the third rotating plate 6 coincide with each other, that is, the pipette tips at the corresponding position can be directly taken out from the opening, and the pipette tips at other positions can be taken when the second rotating plate 5 and the third rotating plate 6 are rotated at the same time, and there are fewer auxiliary actions in the process, and taking the pipette tips from the opening can minimize the exposure of other unused tips to the air, which can reduce the risk of microbial contamination. The device has a simple overall structure and good heat penetration effect. It can take into account the sterilization effect, the taking effect and the storage effect, and is highly convenient to use.
