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 decontamination system for a device, the decontamination system comprising:
a terminal package defining a device receiving area, wherein the terminal package includes a fluid inlet through which sterilant fluid can be delivered to the device receiving area;
an accumulator apparatus comprising an accumulator reservoir in fluid communication with the device receiving area comprising an inlet and an outlet in fluid communication with the device receiving area, further comprising 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 and 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 wherein the accumulator apparatus is integral with the device receiving area; and
a decontamination chamber dimensioned to receive the terminal package, wherein sterilant fluid delivery from the decontamination chamber to the terminal package is conduit-free.
2. The decontamination system of claim 1 , further comprising a motorized pump in fluid communication with the device receiving area, wherein the accumulator apparatus is configured to deliver sterilant fluid to the device receiving area through a flow path separated from a flow path of the motorized pump.
3. The decontamination system 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.
