Device for flow-through ultraviolet light decontamination of microbial contaminants
First Claim
1. A device for administering a fluid, comprising:
- a sterilization cassette comprising a shell, a fluid chamber, and an ultraviolet light transmitting window;
a housing within which the sterilization cassette is removably seated;
an input tube connected to a first portion of the sterilization cassette, wherein the input tube is configured to receive a fluid from a source and deliver the fluid to the chamber;
an ultraviolet light source positioned to direct ultraviolet light through the window into the cassette at an intensity sufficient to kill or render non-reproducible at least one species of a microorganism in the fluid while the fluid is in the chamber;
an outlet tube connected to a second portion of the sterilization cassette, wherein the outlet tube is configured to receive the fluid from the cassette and direct the fluid to a destination;
wherein the input tube, outlet tube, chamber and window are configured so that the fluid mixes within the chamber in a manner so that the fluid is substantially uniformly exposed to the light while in the chamber.

Abstract
A device for administering a fluid includes a sterilization cassette having a shell, a fluid chamber, and an ultraviolet light transmitting window. An input tube directs fluid into the chamber. An ultraviolet light source is positioned to direct ultraviolet light through the window into the fluid chamber at an intensity sufficient to kill or render non-reproducible at least one species of a microorganism in the fluid while the fluid is in the chamber. An outlet tube receives fluid from the cassette and directs the fluid to a destination. The fluid is substantially uniformly exposed to the light while in the chamber. The cassette and light source are contained in a housing that prevents ultraviolet light from escaping the housing.
