Abstract
A device for degassing liquids, in particular liquids used in dialysis, has a degassing unit that includes an ultrasonic unit. Liquids to be degassed are treated in the degassing unit by ultrasound from the ultrasonic unit. Degassed liquids are discharged from the degassing unit through a hollow channel in the ultrasonic unit, and are available for further use.
Claims15
A device for degassing a liquid for dialysis or for an extracorporeal blood treatment, said device comprising:
- a container of a degassing unit to receive the liquid;
- and
- a resonator, which is configured for immersion in the liquid of the container, and which induces a degassing of the liquid through ultrasound,
- with the resonator including a hollow channel via which the degassed liquid is discharged from the container.
1 more element

- introducing a liquid into a container of a degassing unit;
- immersing a resonator into the liquid to be degassed, and degassing the liquid by ultrasonic treatment;
- discharging at least one of the liquid and the separated gas through a hollow channel in the resonator.
