ABSTRACT:
The invention described herein relates to a filter system for sterilization containers which secures a gas permeable filter onto a vented portion of the container. The filter system of the invention includes a locking mechanism that is comfortable and easy to use, and that requires a simple sliding movement of the users hand to lock and unlock the filter system components in place. The invention further includes a filter system structured such that the openings of the filter system plates permit transport of air across the filter while at the same time the openings are arranged to reduce or prevent undesirable physical perforation of the filter. By virtue of its structure, the need for particular rotational positioning of filter components in relation to one another is significantly reduced. The filter system of the invention also reduces or eliminates the need for perimeter gaskets. The invention is useful in a variety of medical applications wherein sterilization of medical devices and instruments is associated with a surgical treatment or procedure.
