Fluid delivery system with multi-dose fluid source

摘要

A fluid delivery system (400A) is generally directed to allowing fluid sources or other fluid delivery components to be reused with multiple fluid targets (318), and includes at least one fluid source (314) fluidly interconnectable with at least one sterilization zone (316) and at least one fluid target (318). This sterilization zone (316) could include one or more sterilization systems that attempt to neutralize contaminants entering the fluid delivery system (400A) by a backflow from the fluid target (318). One such sterilization system (500A-D) includes a container (502a-d) and a flush system (520) for sterilizing the container (502a-d) between uses. Another sterilization system (600) includes a flowpath (604) exposed to an output of an energy source (602) capable of destroying contaminants. Yet another sterilization system could include a sterilizing substance (710) that engages and moves along an interior surface (705) of a housing (704) to treat contamination thereon.

主权项

1. A fluid delivery system, comprising:
a fluid reservoir comprising fluid for multiple fluid targets; a first flowpath extending from said fluid reservoir to a first fluid target; an injector fluidly interconnected with said first flowpath, wherein said first flowpath comprises first and second conduit sections that comprise first and second connectors, respectively, wherein engaging said first connector with said second connector detachably connects said first and second conduit sections together, wherein said first conduit section extends from said second conduit section to said first fluid target and is disposable, wherein each of said fluid reservoir and said injector discharge directly into said second conduit section, wherein a discharge from said injector is directed into said second conduit section, then proceeds through said first conduit section, and then reaches said first fluid target, wherein said second conduit section is reusable for multiple fluid targets by disconnecting said first conduit section from said second conduit section by disengaging said first connector from said second connector, and wherein said injector comprises a syringe that is fluidly connectable with said fluid reservoir by said second conduit section for loading some of said fluid from said fluid reservoir into said syringe for subsequent delivery to a fluid target; a first check valve within said second conduit section so as to be located between said first conduit section and each of said fluid reservoir and said injector; an energy source that provides an output comprising radiative energy of at least one wavelength, wherein at least about 13 centimeters of said first flowpath is exposed to said output from said energy source and comprising at least part of said first conduit section, wherein said energy source is operated to at least one of neutralize and eliminate bacteria to reduce a potential of contaminants migrating from said first fluid target, through said first conduit section, then into said second conduit section, and then back to each of said fluid reservoir and said injector.
