Abstract
A solution for sterilizing one or more hollow components of a device, such as a medical device, is provided. Ultraviolet radiation having one or more predominant wavelength(s) and a sufficient dose is generated and directed to an interior side of the hollow component(s). The predominant wavelength(s) is/are selected to harm one or more target organisms that may be present on the interior side. The ultraviolet radiation can be delivered by a structure that is periodically inserted and retracted into the hollow component. The structure can be configured to provide additional cleaning capability, such as suction, for removing matter that may be present in the hollow component.
Claims21
A medical sterilization system, the system comprising:
- means for generating ultraviolet radiation;
- means for directing the ultraviolet radiation onto an interior side of a hollow component of a medical device, the means for directing including:
- a hollow elongated structure including means for emitting ultraviolet radiation outward from the elongated structure;
- and
- means for placing the elongated structure within the hollow component;
- and
- means for removing matter from the interior side using the elongated structure.
A method of sterilizing a medical device, the method comprising:
- generating ultraviolet radiation using a set of ultraviolet radiation sources;
- directing the ultraviolet radiation onto an interior side of a hollow component of the medical device, the directing including:
- placing a hollow elongated structure within the hollow component;
- and
- emitting ultraviolet radiation outward from the hollow elongated structure;
- and
- removing matter from the interior side using the elongated structure.
A method of sterilizing a hollow elongated structure, the method comprising:
- generating ultraviolet radiation using a set of ultraviolet radiation sources;
- inserting a second elongated structure into the hollow elongated structure, the second elongated structure emitting and directing the ultraviolet radiation onto an interior side of the hollow elongated structure and sensing ultraviolet radiation reflected off of the interior side;
- and
- adjusting at least one property of the generated ultraviolet radiation in response to the sensed ultraviolet radiation.
