DIALYSIS SYSTEM HAVING PERISTALTIC PUMP ARRANGEMENT
First Claim
1. A system for use in dialysis, the system moving fluid from one source to another, the system comprising:
- a machine includingat least three sets of substantially adjacently disposed pressure imposing valve actuators, anda cassette receiving portion,a cassette comprising;
a housing adapted to be removably placed in the cassette receiving portion of the machine, the housing including at least one inlet port adapted to be fluidly coupled to a fluid source, and at least one outlet port;
the housing includingan inlet manifold, the inlet manifold being fluidly coupled to the inlet port, the inlet port being disposed upstream of the inlet manifold;
at least three fluid pathways fluidly coupled to the inlet manifold;
a collection chamber fluidly coupled to the outlet port, the outlet port being disposed downstream of the collection chamber;
the fluid pathways extending parallel flow from the inlet manifold upstream of the fluid pathways to the collection chamber downstream of the fluid pathways, the fluid pathways being adapted to be disposed substantially adjacent respective sets of the valve actuators such that sequential actuation of the valve actuators moves a fluid through the pathways to the collection chamber.

Abstract
A system including a machine and a cassette that moves fluid from one source to another for use in dialysis. The machine includes at least a first set of pressure imposing valve actuators, said valve actuators being pneumatically operated and substantially adjacently disposed, and a cassette receiving portion. The cassette includes a housing adapted to be removably placed in the cassette receiving portion of the machine. The housing includes at least one inlet port adapted to be fluidly coupled to a fluid source, and at least one outlet port. The housing further includes an inlet manifold and a collection chamber, and at least one fluid pathway fluidly coupled to the two. In use, the fluid pathway disposed substantially adjacent the first set of valve actuators such that sequential actuation of the valve actuators moves a fluid through the pathways to the collection chamber.
