the difficulty of sterilization is much higher than that of ordinary solid medical devices
mechanism, the key reason is that the "lumen" is difficult to remove the air inside. The key reason is that the air inside the "lumen" is difficult to get rid of, and the presence of air will affect the effective contact between the sterilizing medium and the inner surface of specific parts of the lumen
, or more accurately, it is the presence of the "lumen" that makes it difficult to achieve the required sterilization results in some parts of the "lumen". More precisely, the existence of the "lumen" makes it difficult for some parts of the "lumen" to achieve the required conditions for successful
sterilization.
In order to ensure effective sterilization of medical devices,
it is necessary to have a clear understanding of "luminal devices"
so that the appropriate type of sterilizer or specific sterilization procedure can be selected for these
devices.
