This invention serves to repurpose existing ethylene oxide sterilization chambers utilizing a novel chemical means of sterilization. Ethylene oxide is a longstanding gaseous sterilant for medical devices but has increasing problems associated with its hazards. Ethylene oxide is a carcinogenic and explosive chemical, and its emissions can be very harmful and cause serious health risks. Due to this, the FDA and many medical device manufacturers are trying to reduce or eliminate the use of the gas. Chlorine dioxide gas is a nearly identical alternative mode of sterilization that is non-carcinogenic and non-explosive. If firms choose to eliminate the use of ethylene oxide but do not want to waste the capital expenditure on existing sterilizers, they can instead utilize the ethylene oxide-to-chlorine dioxide conversion system of the present invention and use an effective and environmentally friendly form of sterilization in a system they already possess.

A sterilization apparatus for sterilizing a respiratory mask is described. The sterilization apparatus comprises a sterilization chamber, an articulating mask support disposed inside the sterilization chamber, a bi-directional fan system disposed inside the sterilization chamber and configured to move air through an air passage to simulate human breathing, and a sterilization agent generator coupled to the sterilization chamber. The bi-directional fan system pumps air that includes the sterilization agent back and forth through the oxygen mask via the air passage, to mimic normal breathing of an individual using the mask.

Disclosed are a sterilization fabric processing equipment and a product manufactured by the processing equipment. The processing equipment includes a processing cavity, a steam device, a chemical tank, a pump set, and an automatic control device. The processing cavity has a working door and an interior for putting a frame and a base fabric overlaid on the frame. The steam device is for delivering steam to the processing cavity. The chemical tank is provided for containing a functional ion chemical and communicated with the steam pipeline through the chemical pipeline. The pump set is for delivering the steam and functional ions into the processing cavity. Under the effect of the predetermined pressure, the functional ions are closely combined to the heated base fabric fiber. The automatic control device is telecommunicatively connected to the steam device and the pump set for controlling their operation.

The present invention provides a breathing assistance apparatus that has a convenient and effective method of cleaning internal conduits inside the apparatus. The breathing assistance apparatus is preferably a gases supply and humidification device. The cleaning method is a method of disinfection that is automated so minimal training is required to disinfect in particular an internal elbow conduit within the device. It is therefore not necessary to dismantle the gases supply and humidification device, therefore, inadvertent damage to the internal parts of the device is avoided. The present invention also provides a method of disinfecting a heated breathing conduit and a patient interface.
