Abstract
Abstract A shunt valve device for connecting an artery and vein to a dialysis machine, such as an artificial kidney or the like, including a shunt valve assembly which has a pair of passages extending therethrough and a valve means for selectively opening and closing the passages. The assembly is mounted on a body member of a person and the passages are connected to the artery and vein. The assembly has means for receiving a pair of conduits from the artificial kidney and holding the conduits in communication with the passages through the assembly so that the valve means can be operated to open the passages and thereby connect the artery and vein to the artificial kidney and permit the flow of blood therebetween. When the valve means is closed, the flow of blood is shunted back to the body member. A bubble sensor is provided between the artificial kidney and the shunt valve assembly to close the valve means on sensing a bubble in the stream of blood leading from the artificial kidney to the shunt valve assembly.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
181 words
A shunt valve device for selectively connecting a patient''s artery and vein to a dialysis machine, such as an artificial kidney or the like, comprising a shunt valve assembly having passage means therethrough and valve means operable to selectively open and close the passage means, means for mounting said shunt valve assembly on a body member of the person, means for connecting the passage means of said shunt valve assembly to the artery and vein of the patient, means on the shunt valve assembly for receiving conduit means from the dialysis machine and holding the conduit means in communication with said passage means whereby said valve means can be operated to open said passage means and thereby connect the artery and vein to the dialysis machine and permit the flow of blood therebetween, means to shunt the flow of blood back to the body member when said passage means is closed, and openings in said shunt valve assembly to permit cleaning at least a portion of said passage means when the flow of blood is shunted back to the body member.
Claim 2
Dependent Claim
181 words
A shunt valve device for selectively connecting a patient''s artery and vein to a dialysis machine, such as an artificial kidney or the like, comprising a shunt valve assembly having passage means therethrough and valve means operable to selectively open and close the passage means, means for mounting said shunt valve assembly on a body member of the person, means for connecting the passage means of said shunt valve assembly to the artery and vein of the patient, means on the shunt valve assembly for receiving conduit means from the dialysis machine and holding the conduit means in communication with said passage means whereby said valve means can be operated to open said passage means and thereby connect the artery and vein to the dialysis machine and permit the flow of blood therebetween, means to shunt the flow of blood back to the body member when said passage means is closed, and openings in said shunt valve assembly to permit cleaning at least a portion of said passage means when the flow of blood is shunted back to the body member.
Claim 3
Dependent Claim
175 words
In a shunt valve device for selectively connecting a patient''s artery and vein to a dialysis machine, such as an artificial kidney or the like, including a shunt valve assembly having passage means therethrough including both through and shunt passages and valve means operable to selectively open and close the passage means, means for mounting said shunt valve assembly on a body member of the patient, means on the shunt valve assembly receiving conduit means from the dialysis machine and holding the conduit means In communication with said passage means whereby said valve means can be operated to open said through passage means and thereby connect the artery and vein to the dialysis machine and permit the flow of blood therebetween, a bubble sensor operatively connected to said conduit means, an actuator means operatively connected to said valve means and to said bubble sensor whereby a bubble passing from the dialysis machine toward said shunt valve assembly is detected by said bubble sensor which in turn actuates said actuator to close said through passage means.
Claim 4
Dependent Claim
175 words
In a shunt valve device for selectively connecting a patient''s artery and vein to a dialysis machine, such as an artificial kidney or the like, including a shunt valve assembly having passage means therethrough including both through and shunt passages and valve means operable to selectively open and close the passage means, means for mounting said shunt valve assembly on a body member of the patient, means on the shunt valve assembly receiving conduit means from the dialysis machine and holding the conduit means In communication with said passage means whereby said valve means can be operated to open said through passage means and thereby connect the artery and vein to the dialysis machine and permit the flow of blood therebetween, a bubble sensor operatively connected to said conduit means, an actuator means operatively connected to said valve means and to said bubble sensor whereby a bubble passing from the dialysis machine toward said shunt valve assembly is detected by said bubble sensor which in turn actuates said actuator to close said through passage means.
Claim 5
Dependent Claim
34 words
The shunt valve device of claim 2 wherein the shunt passage of said valve means shunts the flow of the patient''s blood back to the body member when the through passage means is closed.
Claim 6
Dependent Claim
43 words
The shunt valve device of claim 2 wherein the shunt passage of said valve means shunts the flow of blood back to the dialysis machine when said through passage means are closed so as to return said bubble back to the artificial kidney.
Claim 7
Dependent Claim
21 words
The shunt valve device of claim 2 including a warning device to signal when said bubble sensor has sensed a bubble.
Claim 8
Dependent Claim
169 words
A shunt valve device for selectively connecting a patient''s artery and vein to a dialysis machine, such as an artificial kidney or the like, comprising a shunt valve assembly having through passage means for connecting the artery and vein of the patient to the dialysis machine, a shunt passage means for connecting the patient''s artery and vein together, means for mounting said shunt valve assembly on a body member of the person, means for connecting either of said passage means of said shunt valve assembly to the artery and vein of the person, means on the shunt valve assembly for receiving conduit means from the artificial kidney and holding the conduit means in communication with said through passage means, and valve means operable to selectively open and close said passage means whereby in one position of the valve means the patient''s artery and vein are connected to the dialysis machine to permit the flow of blood therebetween and in another position the patient''s artery and vein are connected together.
Claim 9
Dependent Claim
169 words
A shunt valve device for selectively connecting a patient''s artery and vein to a dialysis machine, such as an artificial kidney or the like, comprising a shunt valve assembly having through passage means for connecting the artery and vein of the patient to the dialysis machine, a shunt passage means for connecting the patient''s artery and vein together, means for mounting said shunt valve assembly on a body member of the person, means for connecting either of said passage means of said shunt valve assembly to the artery and vein of the person, means on the shunt valve assembly for receiving conduit means from the artificial kidney and holding the conduit means in communication with said through passage means, and valve means operable to selectively open and close said passage means whereby in one position of the valve means the patient''s artery and vein are connected to the dialysis machine to permit the flow of blood therebetween and in another position the patient''s artery and vein are connected together.
Claim 10
Dependent Claim
38 words
The shunt valve device of claim 6 including passage means selectively opened and closed by said valve means and operable to shunt the flow of blood back to the dialysis machine when said through passage means is closed.
