In peritoneal dialysis apparatus, flushing liquid is pumped into a supply vessel (4) which is then emptied into the body cavity through a valve (5) and a catheter (6). The supply vessel is then refilled while the cavity is drained back through the catheter into a receptacle (11) of the same weight and dimensions as the supply vessel. The supply vessel and receptacle are suspended at opposite ends of a balance beam (12) and when they are in balance after the receptacle has been filled, a valve (8) isolates the receptacle from the catheter and surplus fluid from the cavity is collected in a measuring vessel (15) through a valve (9), the receptacle being emptied through a valve (10). |
