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.

Claim 1
Independent Claim
215 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 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, control means operatively connected only to said inlet means either for establishing flow of fluid through said inlet and outlet means, in one position of said control means, or for preventing flow of fluid through said inlet and outlet means in another position of said control means, and coupling means on said inlet and outlet means releasably coupling said inlet and outlet means together, said coupling means being operatively connected with said inlet means and outlet means for coupling them to each other when said control means is in said one position for establishing flow of fluid through said inlet and outlet means and for uncoupling said inlet and outlet means from each other when said control means is in said other position preventing the flow of fluid through said inlet and outlet means.
Claim 2
Dependent Claim
215 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 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, control means operatively connected only to said inlet means either for establishing flow of fluid through said inlet and outlet means, in one position of said control means, or for preventing flow of fluid through said inlet and outlet means in another position of said control means, and coupling means on said inlet and outlet means releasably coupling said inlet and outlet means together, said coupling means being operatively connected with said inlet means and outlet means for coupling them to each other when said control means is in said one position for establishing flow of fluid through said inlet and outlet means and for uncoupling said inlet and outlet means from each other when said control means is in said other position preventing the flow of fluid through said inlet and outlet means.
Claim 3
Dependent Claim
47 words
The combination of claim 1 and wherein said pair of mounting means respectively include means carried by said inlet and outlet means for promoting the growth of tissue at the exterior of said inlet and outlet means to achieve the fluid-tight mounting thereof in the body cavity.
Claim 4
Dependent Claim
89 words
The combination of claim 1 and wherein said inlet and outlet means are respectively mounted by said pair of mounting means on portions of the body cavity which are separated from each other, said inlet means including a tubular inlet and said outlet means including a tubular outlet, said control means including a valve connected with said inlet means for opening the latter when said control means is in said one position and for closing the said inlet means when said control means is in said other position thereof.
Claim 5
Dependent Claim
135 words
The combination of claim 1 and wherein said inlet means And outlet means are respectively in the form of a pair of tubular members respectively mounted by said pair of mounting means in parts of the body cavity which are separated from each other, said coupling means including couplings respectively carried by said inlet means and outlet means for interconnecting said inlet and outlet means or for disconnecting said inlet and outlet means from each other, and said control means including a plug carried by said inlet means for closing the latter means when said couplings are uncoupled for placing said control means in said other position thereof, said plug being removed and said couplings being joined to interconnect said inlet means and outlet means when said control means is in said one position thereof.
