The vacuum source having a primary tubing, and the positive pressure fluid chamber connected in fluid communication with the primary tubing via an auxiliary tubing. A fluid piston is slidably received within the positive pressure fluid chamber. A vacuum piston is slidably received within the vacuum chamber and produces a vacuum within the vacuum chamber upon movement of the vacuum piston. The fluid piston and the vacuum piston are each fixedly attached to be movable together within the positive pressure fluid chamber and the vacuum chamber, respectively. A secondary tubing is connected in fluid communication to the vacuum chamber. A manual pump is connected in fluid communication with the primary tubing. A vacuum is producible in the vacuum chamber in response to repeated manipulation of the manual pump.
