Abstract

The disclosed subject matter is directed to volume expanders for use with endoscopes, particularly concerning low-pressure applications, such as sterilization. A volume expander may include an enclosure having a port and a wall including an outer surface and an inner surface, and a vent cap disposed proximate the port. The port may be a single port to which the vent cap is affixed. The volume expander permits gas within recesses of an endoscope to expand, but provides a barrier between the recesses of the endoscope and the surrounding environment.

Description

technical field [0001] The subject matter disclosed herein relates to sterilizing endoscopes in pressure chambers. Background technique [0002] Medical devices are often sterilized prior to use in order to minimize the possibility of using a contaminated device on a subject, which could result in an infection of the subject. Various sterilization techniques can be employed, such as steam, hydrogen peroxide, and gas phase sterilization with or without gas plasma and ethylene oxide (EtO). Each of these methods depends to some extent on the rate of diffusion of a sterilizing fluid, usually a gas, over the medical device to be sterilized. [0003] Certain sterilization techniques are performed at pressures other than ambient or atmospheric pressure. For example, the advanced sterilization products of Ethicon LLC division of Johnson & Johnson Company system, NX system or The 100NX system is an example of a sterilization system that vaporizes hydrogen peroxide and operate...
