Abstract

Apparatus and methods are described including a cartridge (214), which includes a first port (386a), a second port (386b), and a third port (386c), and which holds tubes such that respective proximal portions of a purging-fluid tube (196a), a waste tube (196b), and a flushing tube (196c) pass through the first port (386a), respective distal portions of the purging-fluid tube (196a), the waste tube (196b), and a pressure-sensing tube (196d) pass through the second port (386b), and a distal portion of the flushing tube (196c) and a proximal portion of the pressure-sensing tube (196d) pass through the third port (386c). Other applications are also described.
