Description

Technical Field

[0001] The utility model relates to the technical field of biological indicators, in particular to a biological indicator and a packaging box thereof. Background Art

[0002] Biological indicators are microbial products used to verify the effectiveness of sterilization processes. They typically contain spores of highly resistant microorganisms, such as Bacillus stearothermophilus or Bacillus melanophilus, which have a high degree of survival under specific sterilization conditions. By monitoring the survival status of these spores before and after sterilization, it is possible to indirectly assess whether the sterilization equipment and procedures have achieved the intended sterilization effect. Within a closed system containing a bacterial plate and a color developer, after sterilization, the biological indicator is removed and incubated for a period of time. If it is a self-contained biological indicator, the color change can be directly observed to determine the success of sterilization.

[0003] Currently, some biological indicators are prepared by directly loading bacterial slices and colorants into a covered tube body, then opening the tube body lid and placing it into a high-temperature sterilization device. After sterilization, the biological indicator is taken out for testing. The biological indicator needs to be sealed and then the bacterial slice inside the biological indicator is immersed in the colorant. However, this type of biological indicator is prone to bacterial colonies being dispersed after the lid is opened, and then the lid must be tightly closed again after sterilization. This operation is cumbersome and can easily lead to deviations in the detection results.

[0004] In summary, there is a need for a biological indicator that is simple to operate and produces accurate results. Utility Model Content

[0034] According to the above structure, the following effects can be achieved:

[0035] By placing the biological indicator into the packaging mechanism 7 and inserting the packaging mechanism 7 into the box body 6, the biological indicator can be well packaged and protected. When testing the sterilization effect, it is only necessary to place the high-temperature sterilized biological indicator into the box body 6, and use the flip clamp assembly 8 and the clamping column 63 to clamp off the internal structure of the biological indicator, without having to find a clamp to perform the clamping operation, thereby improving the convenience of biological indicator testing.

[0049] Press first Figures 1-6 The knob 88 is rotated to drive the second rotating shaft 84 to rotate, and the gear 87 drives the pull-up bar 73. The pull-up bar 73 pushes the inserting plate 714 to push out the inner sealing plate 712, and then pulls the outer sealing plate 711 to open the box body 6. The outer sealing plate 711 is further pulled to pull the supporting plate 716 out of the box body 6, and the biological indicator is removed from the first shelf 721. When the supporting plate 716 is pulled out, it drives the fixed plate 717 to move, and the fixed plate 717 drives the spring 718 to stretch;

[0050] Remove the sealing plug 3 for removing the biological indicator, and then place the biological indicator into the high-temperature sterilization equipment.

The pull-over bar 73 drives the gear 87 to rotate. The second rotating shaft 84 rotates on the second bracket 86. The second bracket 82 and the second bracket plate 81 drive the biological indicator to flip over. The flipping paper clip column 63 clamps the outer tube 1, squeezes the outer tube 1, and cuts off the internal glass reagent tube 4. The color developer flows out and immerses the bacterial slice 5. Then, the biological indicator is inserted into the ring 713, and the color developer inside the outer tube 1 is observed and compared with the comparison card plate 715 to detect the sterilization effect of the high-temperature sterilization equipment.
