Abstract:
1. An apparatus for continuously aspirating a fluid from a fluid source comprising: a vacuum source; a first container forming a first chamber and operatively connected to the vacuum source, a first level sensor positioned within the first chamber and sensing a level of the fluid within the first chamber; a second container forming a second chamber and operatively connected to the vacuum source, a second level sensor positioned within the second chamber and sensing a level of the fluid within the second chamber; a fluid collection tube providing communication between the fluid source and each of the first chamber and the second chamber; and a relay receiving at least one signal from at least one of the first level sensor and the second level sensor, and the relay responsively either activating a first solenoid valve to expose the vacuum source to the first chamber while preventing communication between the vacuum source and the second chamber or activating a second solenoid valve to expose the vacuum source to the second chamber while preventing communication between the vacuum source and the first chamber, to continuously aspirate at least a portion of the fluid from the fluid source.
