DEVICES, SYSTEMS AND METHODS FOR TREATING MEDICAL DEVICES
HAVING PASSAGEWAYS WITH OZONE GAS
TECHNICAL FIELD
The present disclosure generally relates to ozone gas treatment of medical devices and
more particularly, is related to devices, systems and methods using agents or gas, such as ozone
gas, for cleaning, disinfecting and sterilizing medical devices in a ozone device with multiple
cleaning, disinfecting and sterilizing properties, with one or more receptacles, and receiving
ports and chambers for ease of cleaning, disinfecting and sterilizing medical devices, medical
instruments and medical passageways, such as hoses and/or tubes.
BACKGROUND OF THE DISCLOSURE
Medical devices, medical instruments and medical accessories (collectively “medical
devices”) require varying degrees of cleaning, disinfection and/or sterilization to prevent bacteria
and mold build-up and for safe use and reuse of devices on the same patient and between
patients. There are many types of medical devices that have multiple pieces and accessories that
require cleaning, disinfection and/or sterilization including, without limitation, hoses, tubes,
facemasks, probes, compartments, reservoirs, irrigation systems, pumps and other accessories.
Current devices, systems and methods for preparing medical devices for use and/or reuse have
proved to be tiring and difficult for users, hospitals and other medical device provider services.
Devices often require daily and weekly maintenance steps to prevent bacteria and mold buildup,
requiring each part of the device to be cleaned individually, which is difficult and time
consuming for users on a daily or weekly basis. Other cleaning methods include soaking the
component parts of a medical device in solvents or mixtures for instance of vinegar and water toWO 2017/189916 PCT/US2017/029950
disinfect the component parts. Because of the inherent nature for many medical devices to
collect bacteria and mold, a number of other products are available for consumers to make
medical devices safer to use, including but not limited to sprays, UV light devices, cleaning
wipes and cleaning brushes.
Ozone gas is powerful and effective for removal of odors, impurities and dangerous
pathogens, working by exchanging electron charge with particles that ozone comes into contact
with to form oxygen, O , from the unstable ozone 03. This process is particularly useful for
purifying air and water and for killing bacteria and microorganisms that the ozone comes into
contact with. Ozonators can be used to create ozone from oxygen molecules, often by applying
ultraviolet light to the oxygen. Ozone gas is made of oxygen molecules that have been ionized
a
by radiation to form groups of three oxygen atoms, O , and may be created, for instance in a
device, using an ozonator, air, and the application of ultraviolet light to convert oxygen into
ozone gas. However, while ozone gas is a powerful cleaning, disinfecting and sterilizing gas,
ozone gas must be contained and controlled as it is not safe for users to breath ozone gas until it
has safely converted back to oxygen. The amount of time that is needed for ozone to convert
safely from ozone to oxygen varies significantly based on the amount of ozone used in a
treatment cycle, in some embodiments ranging from 1 minute to 24 hours.
It is a long felt need in the art to provide a device, systems and methods that can treat
medical devices and medical device passageways with one device using ozone gas, requiring
minimum disassembly and yet part specific treatment, all in one or more connected and closed-
loop systems for safe use treatment with ozone gas and ease of use by a user. It is further a need
to provide connector units to connect a variety of medical devices and medical device
passageways for treatment with ozone gas.

features, and advantages be included within this description, be within the scope of the present
disclosure, and be protected by the accompanying claims.
