Further it is possible to eliminate carbonyl compounds transferred from the blood to the peritoneal cavity of the patient during peritoneal dialysis treatment by adding the trapping agent to the peritoneal dialysate or by circulating the fluid through a carbonyl compound-trapping cartridge.

Why it's free to use
- Filed August 23, 1999 and granted June 4, 2013. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended August 23, 2019.

- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
