Abstract
A method and a device for collecting a dialysate sample for a qualitative and quantitative analysis of all the dialysate collected during replacement therapy for renal failure. In a preferred embodiment, the device (10) comprises a buffer receptacle (20) consisting of a cylindrical container on a separator (30). The separator (30) has a collecting chamber (36) with a number of calibrated ducts (39 and 42) formed at its periphery. Calibrated ducts (39) open into a flow channel (38) and the dialysate conveyed by the ducts passes into a discharge duct (34), whereas calibrated ducts (42) lead to a collector (41) communicating with a duct (35). The dialysate collected at the outlet of duct (34) is analyzed. This device allows the dialysate generated during a dialysis process to be sampled continuously and the composition of this sample represents that of all the dialysate produced.
