Steam Sterilization Cycles, Part 3: Steam-Air-Mix Cycle

Written by:Arthur Trapotsis

使用蒸汽高压业时，对于所有负载要求识别，理解和创建适当的灭菌周期至关重要。因此，作为我们系列讨论的一部分Steam Sterilization Cycles, this third article is designed to explore the Steam-Air-Mix Cycle, a more advanced steam灭菌周期用于独特的应用。

蒸汽空气混合周期

Certain types of sterilization loads may require steam sterilization cycles that stray from the standard Gravity,Liquids, or Vacuum types.

以例如使用三个标准循环之一对液体填充注射器进行消毒。立即在这里提出了一个问题：随着注射器的加热，注射器内部的液体会膨胀，对应该将液体固定在内部的塞子上施加压力。当容器用液体（内部没有空气）顶上，这一点尤其重要。如果空气位于液体旁边的容器中，则压力也会增加。如果塞子无法抵抗这些压力，则塞子将被迫脱离位置，甚至可能从注射器体中弹出。现在，注射器不仅将无法使用，而且注射器内部的任何东西都会使其余的负载和您的高压釜室弄乱。

明显的解决方案是增加高压釜室的压力，以平衡注射器的内部和外部压力（或其他密封容器）。如果注射器外部的压力等于内部的压力，则塞子不应移动。但是这是如何完成的？

One way to increase autoclave chamber pressure is to simply inject more steam. Unfortunately, as the steam pressure rises, so does the temperature. When the temperature rises, the contents of the container will heat even more, causing the internal pressure to continue to rise as well. A Steam-Air Mix Cycle solves this issue by injecting compressed air into the autoclave chamber during the sterilization phase in order to artificially raise the pressure. Steam continues to be injected into the chamber as needed in order to maintain the cycle’s temperature setting.

后the sterilization phase is complete, it is necessary to maintain an elevated chamber pressure during the exhaust phase in order to keep the syringe intact. However, as the temperature falls, the internal pressure of the container will begin to fall as well, potentially causing the reverse-effect where the external pressure from the chamber compromises the container. To solve this, the chamber pressure is slowly reduced as the temperature falls.

The Steam-Air Mix Cycle option requires you to have a compressed air supply, and it is recommended for applications where a liquid is being sterilized in a sealed container that may be affected by pressure imbalances.
