ABSTRACT:
A fluid dispenser and method for applying a selected fluid to a desired location includes a reservoir containing the fluid, the reservoir includes a resilient body having a first end and a second end, a first end sealing cap, and a second end sealing cap assembly with a penetrable elastomeric member to define a reservoir interior. The body includes bellows oriented to retract or extend the body between the first end and the second end creating a variable reservoir interior volume. Also included is an applicator having a proximal end and a distal end, the proximal end includes a non coring cannula with a lumen having an insertion end adapted to penetrate through the elastomeric member and protrude into the reservoir interior. This enables fluid communication between the reservoir interior and the lumen; the distal end also includes an application element that is in fluid communication with the lumen.
