Abstract
Apparatus for rinsing body cavities includes a double tube pump (1) for simultaneously pumping fluid into a storage vessel (4) for subsequent feed through a catheter (K) and pumping discharged fluid from a measuring vessel (9) at the same rate, so that surplus fluid with the discharge can be measured. The measuring vessel has sensors (11,12) which switch on and switch off the pump when fluid in the measuring vessel falls or rises to predetermined levels. An additional pump (13) may be provided for the surplus fluid extraction. The double tube pump comprises a pair of parallel identical tubes (24a, 24b) with joined end connections (34,35) in a stator (21) which are squeezed by common rollers (32) mounted in a rotor (27).
