Company's Subsidiary, AcryMed, Responds to Plea from Chinese

Partner; Ships Cases of SilvaSorb(R) Antimicrobial Gel to Quake Site

                      With Help from Local FedEx

LAKE FOREST, Calif.--(BUSINESS WIRE)--May 20, 2008--I-Flow Corporation (NASDAQ:IFLO), through its wholly-owned subsidiary AcryMed, announced today it has donated 1,000 tubes of its SilvaSorb antimicrobial gel product to the Red Cross of China for distribution to earthquake victims in Sichuan, China. The company offered its help last week by donating the available product and arranged for immediate shipping to China after a plea from its Chinese partner.

According to reports out of China, the recent earthquake has left thousands injured and created unclean conditions, raising fear of the spread of dangerous infections. AcryMed's SilvaSorb is a unique topical gel containing a highly effective silver antimicrobial compound that kills bacteria and fungus commonly associated with wounds and burns. Those who use it may significantly reduce the risk of contracting a life-threatening infection.

"Stemming the tide of infections will be critical to saving lives," said AcryMed's chief technology officer and founder, Bruce Gibbins, a microbiologist. "SilvaSorb is a gel that requires no training to apply and the antimicrobial technology it contains can have a significant impact on reducing life-threatening infections contracted by the wounded. We were glad to be able to assist the relief efforts."

Gibbins further commented, "Three years ago we were also able to assist Medical Teams International in helping the Tsunami victims in South Asia. As a company that is committed to helping those who really need it, we are proud to be able to contribute what we can."

SilvaSorb was recently cleared by the FDA for over the counter distribution and is available as a CVS brand anti-microbial silver gel in CVS/pharmacy stores throughout the United States. SilvaSorb is also distributed to medical professionals in the U.S. by Medline Industries.
