Claim 7

The combination of claim 4 including a housing containing said control means, said receptacle being associated with the housing and openly upwardly exposed.

Claim 8

The combination of claim 4 including said artificial kidney, having blood flow ports and ducting connecting said kidney blood flow ports with said apparatus to sequentially pass said water flow and said dilute treating liquid flow to the kidney.

Claim 9

Claim 10

In artificial kidney treatment apparatus, the combination comprising: a. said apparatus having a clean water inlet, b. said apparatus also having an inlet means for kidney treating liquid concentrate, c. said apparatus including means to deliver the concentrate into a water stream being circulated to and through the kidney, whereby the kidney may be washed by aqueously diluted treated liquid, and d. automatic control means to effect and control the sequential and alternate delivery of water flow to the kidney and dilute treating liquid flow to the kidney, e. the concentrate inlet means being defined by a pair of upwardly opening receptacles each sized to receive a concentrate container from which concentrate is adapted to drain, each receptacle having porting to pass concentrate draining from the container received in that receptacle, and wherein said delivery means includes a venturi to pass clean inlet water, there being ducting to communicate the porting of each receptacle with the venturi at a location such that concentrate liquid is drawn into the inlet water stream, the control means including valves to control concentrate liquid flow from the receptacle porting to the venturi via said ducting, and a timer responsive valve controller to selectively open and close the valves at times controlled by the controller.

Claim 11

In artificial kidney treatment apparatus, the combination comprising: a. said apparatus having a clean water inlet, b. said apparatus also having an inlet means for kidney treating liquid concentrate, c. said apparatus including means to deliver the concentrate into a water stream being circulated to and through the kidney, whereby the kidney may be washed by aqueously diluted treated liquid, and d. automatic control means to effect and control the sequential and alternate delivery of water flow to the kidney and dilute treating liquid flow to the kidney, e. the concentrate inlet means being defined by a pair of upwardly opening receptacles each sized to receive a concentrate container from which concentrate is adapted to drain, each receptacle having porting to pass concentrate draining from the container received in that receptacle, and wherein said delivery means includes a venturi to pass clean inlet water, there being ducting to communicate the porting of each receptacle with the venturi at a location such that concentrate liquid is drawn into the inlet water stream, the control means including valves to control concentrate liquid flow from the receptacle porting to the venturi via said ducting, and a timer responsive valve controller to selectively open and close the valves at times controlled by the controller.

Claim 12

The combination of claim 8 including a two-stage water pressure regulator connected in series with said venturi to control the pressure of water delivered thereto, the controller controlling the regulator to increase water pressure delivery to the venturi when cleaning liquid is also delivered to the venturi from one of the containers.

Claim 13

The combination of claim 8 including said containers in said receptacles.

Claim 14

The combination of claim 10 wherein one container contains cleaning liquid and the other container contains sterilizer liquid.

Claim 15

In artificial kidney treatment apparatus, the combination comprising: a. said apparatus having a clean water inlet, b. said apparatus also having an inlet means for kidNey treating liquid concentrate, c. said apparatus including means to deliver the concentrate into a water stream being circulated to and through the kidney, whereby the kidney may be washed by aqueously diluted treated liquid, and d. automatic control means to effect and control the sequential and alternate delivery of water flow to the blood compartment of the kidney and dilute treating liquid flow to the kidney, e. and including said artificial kidney disconnected from a patient, said kidney having blood flow ports connectible with a patient, and ducting connecting said kidney blood flow ports with said apparatus to sequentially pass said water flow and said dilute treating liquid flow to the kidney.
