Abstract

The invention provides a method of introducing a sterilized product into a controlled environment. The sterilized product is enclosed in a substantially hermetically sealed first layer, which is enclosed in a substantially hermetically sealed second layer, which is enclosed in a substantially hermetically sealed third layer, which is enclosed in a substantially hermetically sealed fourth layer. The method includes removing the fourth layer in a first environment (having a first sterility), removing the third layer in a controlled second environment (having a predetermined second sterility that is higher than the first sterility), removing the second layer in a controlled third environment (having a predetermined third sterility that is higher than the second sterility), and removing the first layer in a controlled fourth environment (with a predetermined fourth sterility that is higher than the third sterility) to expose the sterilized product.

Dependent claims

A method of introducing a sterilized product that meets the requirements for a Grade A controlled environment into a controlled environment, the sterilized product being enclosed in a first layer that is substantially hermetically sealed to form a first sealed enclosure, the first sealed enclosure being enclosed in a second layer that is substantially hermetically sealed to form a second sealed enclosure, the second sealed enclosure being enclosed in a third layer that is substantially hermetically sealed to form a third sealed enclosure, and the third sealed enclosure being enclosed in a fourth layer that is substantially hermetically sealed to form a fourth sealed enclosure, the method comprising:

removing the fourth layer in a first environment with a first sterility to expose the third sealed enclosure;
transporting the third sealed enclosure to a second environment;
removing the third layer in the second environment to expose the second sealed enclosure, wherein the second environment is a controlled environment with a predetermined second sterility that is higher than the first sterility;
transporting the second sealed enclosure to a third environment
removing the second layer in the third environment to expose the first sealed enclosure, wherein the third environment is a controlled environment with a predetermined third sterility that is higher than the second sterility;
transporting the first sealed enclosure to a fourth environment;
and
removing the first layer in the fourth environment to expose the sterilized product, wherein the fourth environment is a controlled environment with a predetermined fourth sterility that is higher than the third sterility.
