ABSTRACT:
The present invention provides a portable device for storing and dispensing sterile saline for use by contact lens wearers and the like. The device comprises a hollow vessel in which non-sterile saline is stored, which has an outlet on which a housing is mounted. The sterilized saline is dispensed through a second outlet in the housing and a passage communicates between the vessel outlet and the housing outlets. A first valve opens and closes the housing outlet. A liquid-sterilizing filter is mounted in the housing across the liquid passage. A pump for increasing and reducing pressure in the interior of the housing chamber causes the saline to be drawn into an intermediate chamber in the housing and then forces it through the liquid-sterilizing filter and out the housing outlet.
