Accumulator apparatus for use in sterilization
A decontamination system for a device, such as a lumen device, is provided. The decontamination system includes a terminal package defining a device receiving area. The terminal package includes a fluid inlet through which sterilant fluid can be delivered to the device receiving area. An accumulator apparatus is provided that is configured to switch between trapping sterilant fluid delivered into the device receiving area and delivering sterilant fluid to the device receiving area based on pressure changes in the device receiving area.
1. A terminal package for use in a decontaminating system, the terminal package comprising:
a container dimensioned to receive a device, wherein the container defines a device receiving area;
a fluid inlet defined in the container to deliver a sterilant fluid to the device receiving area;
an accumulator apparatus connected to the container, wherein the accumulator apparatus is configured to switch between trapping sterilant fluid delivered into the device receiving area and delivering sterilant fluid to the device receiving area based on pressure changes in the device receiving area and includes an accumulator reservoir having an inlet and an outlet in fluid communication with the device receiving area, the reservoir being in fluid communication with the device receiving area; and
a first one-way valve configured to allow flow into the accumulator reservoir from the device receiving area through the inlet, but prevent flow from the accumulator reservoir into the device receiving area through the inlet.
2. The device container of claim 1 , further comprising a second one-way valve configured to allow flow into the device receiving area from the accumulator reservoir through the outlet, but prevent flow from the device receiving area into the accumulator reservoir through the outlet.
3. The device container of claim 1 , wherein the accumulator apparatus is integral with the container.
4. The device container of claim 3 , wherein the accumulator apparatus is in fluid communication with a fluid connector.
5. The device container of claim 4 , wherein the accumulator apparatus is constructed from one or more of stainless steel, aluminum, polypropylene, polytetrafluoroethylene (PTFE), polyethylene, high density polyethylene (HDPE) and/or fluorinated ethylene propylene (FEP).
