Abstract
Sterile solution delivery and venting devices for use with multi-dose sterile solution packages are disclosed. The devices include a positive acting, normally closed check valve which opens to express solution from the package when squeezing pressure is applied and which automatically closes when the pressure is released. A hydrophobic filter is included to sterilize the replacement air which enters the package upon release of the squeezing pressure.
