Method and arrangement for venting gases from a container having a powdered concentrate for use in hemodialysis
First Claim
1. In a system for use with a dialysis apparatus, the system including a container having an inlet and at least one gas outlet having a gas outlet control valve, a hydrochamber disposed upstream of the container, a first hydraulic line, the first hydraulic line fluidly coupling the gas outlet of the container to the hydrochamber, the gas outlet control valve disposed in said first hydraulic line to provide selective gas flow through the first hydraulic line, a second hydraulic line fluidly coupling the hydrochamber to the container inlet, and an inlet control valve disposed in the second hydraulic line to selectively control flow of fluid from the hydrochamber to the container, a method for venting gases from the container, the method comprising the steps of:
- opening the gas outlet control valve to vent gases from the container to the hydrochamber, the gas outlet control valve selectively fluidly coupling the gas outlet of the container directly to the hydrochamber; and
closing the gas outlet control valve when at least a portion of the gases contained within the container are vented from the container to the hydrochamber.

12. A system for use with a dialysis apparatus, the system comprising
a container having an inlet and at least one gas outlet, a hydrochamber, a first hydraulic line, the first hydraulic line fluidly coupling the gas outlet of the container directly to the hydrochamber, a gas outlet control valve disposed in said first hydraulic line to provide selective gas flow through the first hydraulic line, a second hydraulic line fluidly coupling the hydrochamber to the container inlet, and an inlet control valve disposed in the second hydraulic line to selectively control flow of fluid from the hydrochamber to the container.

18. In a system for use with a dialysis apparatus, the system including a container having an inlet, at least one gas outlet having a gas outlet control valve, and a solution outlet control valve at a solution outlet, the system also including a hydrochamber disposed upstream of the container, a first hydraulic line, the first hydraulic line fluidly coupling the gas outlet of the container to the hydrochamber, the gas outlet control valve disposed in said first hydraulic line to provide selective gas flow through the first hydraulic line, a second hydraulic line fluidly coupling the hydrochamber to the container inlet, and an inlet control valve disposed in the second hydraulic line to selectively control flow of fluid from the hydrochamber to the container, a method for venting gases from the container, the method comprising the steps of:
-
opening the solution outlet control valve at the solution outlet of the container to advance the solution to the dialysis apparatus; subsequently opening the gas outlet control valve to vent gases from the container directly to the hydrochamber, the gas outlet control valve selectively fluidly coupling the gas outlet of the container to the hydrochamber; closing the gas outlet control valve when at least a portion of the gases contained within the container are vented from the container to the hydrochamber; advancing fluid through the hydrochamber to the container inlet.
