First Claim
Patent Images
1. A degassing vessel for use in dialysis;
- comprising;
a fluid inlet in the degassing vessel fluidly connected to a flow restriction;
a fluid outlet in the degassing vessel for fluid connection to a fluid pump downstream of the degassing vessel;
a gas outlet for connection to a vacuum pump;
one or more sensors contacting the degassed fluid downstream of the degassing vessel;
a degas sprayer;
wherein fluid entering the degassing vessel through the fluid inlet passes through the degas sprayer;
and a control system, the control system programmed to control a pressure in the degassing vessel based on an amount of gas to be removed from a fluid entering the degassing vessel.

Abstract
The degassing system can include a degassing vessel and can utilize a vacuum pump and a fluid pump located downstream of the degassing vessel to control the pressure within the degassing vessel in order to control the concentration of gases in fluid exiting the degassing system. The degassing system can further comprise sensors in communication with the pumps to control the rate of flow and pressure through the degassing system. The degassing system may be placed in a dialysate flow path to remove dissolved gases including carbon dioxide from the dialysate.
