Abstract
A breather assembly for a peristaltic pump comprises a breather tube and a cap connected to the breather tube. The cap comprises a sealing portion. One of the breather tube and the cap comprises a guide track and the other of the breather tube and the cap comprises a protrusion. The guide track comprises first and second sections separated by a first formation. The second section is bounded at its distal end by a second formation. The protrusion can pass the first formation when a first force is applied to the cap. The protrusion can pass the second formation when a second force is applied to the cap. When the protrusion is located within the first section, the sealing portion of the cap seals against the breather tube. When the protrusion is located within the second section, the sealing portion of the cap is spaced from the breather tube.
