Abstract
The present disclosure describes a flow reversing valve, along with associated methods and systems for providing forward flow, reverse flow, and bypass flow modes of operation, and integrating them into patient treatment systems, including those used for treating and inducing hyperthermia.
Claims17
1-17. (canceled)
A system for treating a patient, the system comprising:
- at least one pump;
- a flow reversing valve fluidly connected to the at least one pump;
- a patient inlet line fluidly connected to the flow reversing valve;
- a patient return line fluidly connected to the flow reversing valve;
- a system inlet line fluidly connected to the flow reversing valve;
- and
- a system outlet line fluidly connected to the flow reversing valve,
- wherein a first rotation of at least one portion of the flow reversing valve causes flow in at least one portion of the system to reverse directions.
5 more elements
A method of treating a patient comprising:
- providing at least two system fluid lines and at least two patient fluid lines, the at least two system fluid lines and the at least two patient fluid lines fluidly connected to a flow reversing valve;
- initiating a flow of fluid through the flow reversing valve;
- checking at least one of the at least two system fluid lines and the at least two patient fluid lines for at least one of a blockage and debris;
- and
- rotating at least one portion of the flow reversing valve through a first angle, thereby resulting in flow reversal in at least one of the at least two system fluid lines and the at least two patient fluid lines.
