Abstract
A device for removing fluid from a flexible tube includes a container having an opening and a sharp cannula located inside the container. The cannula is positioned to puncture the flexible tube when it is inserted through the opening, so that fluid in the tube flows through the cannula and collects at the bottom of the container. A diluent may be added to the container through the same opening. The cannula is affixed to the wall of the container by passing the cannula through a dimple formed in that wall. A spout formed in the container allows fluid to be dispensed from the container. When dispensing fluid from the container, the opening is preferably sealed with a finger, and the size of the spout determines the rate at which fluid flows out of the spout.
