There is disclosed a peristaltic pump, comprising: a resilient tube having a primary tube chamber and an auxiliary tube chamber which are integrally formed with one another, wherein the primary tube chamber is configured to receive a working fluid and the auxiliary tube chamber is configured to receive the working fluid upon rupture of a wall of the primary tube chamber; and a sensor configured to detect working fluid in the auxiliary tube chamber. There is also disclosed a resilient tube for a peristaltic pump, comprising: a primary tube chamber and an auxiliary tube chamber which are integrally formed with one another, wherein the primary tube chamber is configured to receive a working fluid and the auxiliary tube chamber is configured to receive the working fluid upon rupture of a wall of the primary tube chamber.
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.
A breather assembly for a peristaltic pump comprising a breather tube and a cap. The cap is detachably connected to the breather tube and comprises a sealing portion. One of the breather tube and the cap comprise a guide track and the other of the breather tube and the cap comprises a protrusion which engages the guide track. The guide track comprises in series a first section and a second section which is separated from the first section by a first formation and is bounded at its distal end by a second formation. The protrusion is able to pass the first formation only when a predetermined first force is applied to the cap and the protrusion is able to pass the second formation only when a predetermined second force is applied to the cap such that the first and second formations prevent free movement of the protrusion along the guide track. When the protrusion is located within the first section, the sealing portion of the cap seals against the breather tube, and, when the protrusion is located within the second section, the sealing portion of the cap is spaced from the breather tube to allow fluid to pass out of the breather tube.

End fitting for a tube housed by a cavity and a method of installing a tube in a cavity
An end fitting for a tube housed by a cavity and a method of installing a tube in a cavity are described which use a compression ring that defines a void having an axial extent and a radial extent. The compression ring is compressed between a bracket of the end fitting and a port of the cavity by drawing the bracket axially towards the port. This seals the port and deforms the void defined by the compression ring. The deformation of the void reduces its axial extent and increases its radial extent, thereby compressing the tube against an insert received within the interior of the tube.
