Description

Technical Field

[0001] The utility model relates to the technical field of biological product auxiliary equipment, in particular to a biological indicator protection device. Background Art

[0002] Biological indicators are a special type of live microbial products that can be used to confirm the performance of sterilization equipment, validate sterilization procedures, monitor the sterilization effect of the production process, etc. They are defined as contaminated carriers that have a certain resistance to specific sterilization treatments and are packed in inner packaging for use. Due to their special nature, biological indicators need to be stored in sterilization cabinets. Traditional biological indicator protection devices are generally for pipeline steam sterilization biological indicator storage or laboratory storage protection. In the sterilization process microbial challenge test of large-volume injections, biological indicators need to be placed in the product solution. Glass ampoules without effective protection are fragile and will lead to contamination of the entire batch of products and the production environment, thereby causing production environment pollution, product quality risks and sterilization process validation failure.

[0003] For example, the Chinese utility model patent with application number CN202022940671.X discloses "A biological indicator protection device", which is used to protect biological indicators in large-volume injection microbial challenge tests to prevent biological indicators from breakage, avoid pollution of the production environment and product quality risks, and ensure full contact between the product solution and the biological indicator, thereby ensuring the penetration effect of the microbial challenge test and the effectiveness of the sterilization process verification.

[0004] However, due to the special nature of biological indicators, they need to be stored in a sterilizer. Due to their low density, small-dose reagent bottles float in the liquid in the sterilizer, resulting in poor stability of the small-dose reagent bottles in the liquid. When the liquid level fluctuates, the small-dose reagent bottles will move due to their small weight, causing adjacent small-dose reagent bottles to collide and break. Utility Model Content
