Abstract
Abstract A device for controlling the flow of fluid in a living creature. The device has an inlet and outlet both of which are mounted fluid-tightly in a body cavity in a position compelling the fluid which is to be controlled to flow into said inlet before reaching the outlet. Between the inlet and outlet there is a control structure which in one position provides for flow of fluid in a given condition through the inlet and the outlet and which in another position prevents the flow of fluid in this given condition through the inlet and outlet. This control structure can provide for fluid flow at all times while chemically treating the fluid to prevent it from having a given condition, or the control structure can in one position cut off the flow of fluid and in another position reestablish the flow of fluid.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
205 words
In a device for regulating the flow of fluid in the body of a living creature, inlet means and outlet means for respectively receiving and discharging the fluid, a pair of mounting means coacting with said inlet means and outlet means for respectively mounting said inlet means and outlet means fluid-tightly in a body cavity with said inlet means situated in the path of fluid flow so that the fluid must first flow into said inlet means before reaching said outlet means, and control means located between and operatively connected to said inlet and outlet means either for establishing flow of body fluid in a given condition through said inlet and outlet means, in one position of said control means, or for selectively preventing flow of certain components in said body fluid in said given condition through said inlet and outlet means in another position of said control means, said control means providing for fluid flow through said inlet means and outlet means in both of said positions of said control means, and said control means having means thereinfor coacting with the fluid, when said control means is in said other position thereof, for changing the condition of the fluid from said given condition thereof.
Claim 2
Dependent Claim
205 words
In a device for regulating the flow of fluid in the body of a living creature, inlet means and outlet means for respectively receiving and discharging the fluid, a pair of mounting means coacting with said inlet means and outlet means for respectively mounting said inlet means and outlet means fluid-tightly in a body cavity with said inlet means situated in the path of fluid flow so that the fluid must first flow into said inlet means before reaching said outlet means, and control means located between and operatively connected to said inlet and outlet means either for establishing flow of body fluid in a given condition through said inlet and outlet means, in one position of said control means, or for selectively preventing flow of certain components in said body fluid in said given condition through said inlet and outlet means in another position of said control means, said control means providing for fluid flow through said inlet means and outlet means in both of said positions of said control means, and said control means having means thereinfor coacting with the fluid, when said control means is in said other position thereof, for changing the condition of the fluid from said given condition thereof.
Claim 3
Dependent Claim
44 words
The combination of claim 1 and wherein said means in said control means coacts with the body fluid when said control means is in said other position thereof for reacting chemically with the body fluid to change the condition thereof from said given condition.
Claim 4
Dependent Claim
104 words
The combination of claIm 2 and wherein said control means is a valve situated between said inlet means and outlet means and having first and second valve passages which are separate from each other, said valve in said one position providing for direct communication between said inlet means and outlet means through said first valve passage without changing the condition of the body fluid and said valve in said other position of said control means directing body fluid received from said inlet means before it reaches said outlet means through said second valve passage, the latter containing a material for treating the body fluid.
Claim 5
Dependent Claim
26 words
The combination of claim 3 and wherein said material is a layer of copper which lines said second valve passage for reacting with the body fluid.
