The quantities of fluid which are fed to a patient (P) by fluid supply devices (10) and the quantities of fluid which are excreted by the patient as urine, wound drainage fluid or similar, received in corresponding receptacles (20a, 20b, 20c) are counterbalanced by a fluid manager (15). The fluid manager (15) controls the fluid supply devices (10) in accordance with the result of the counterbalancing process. Each receptacle (20a, 20b, 20c) comprises a receiving container (22) and a secretion quantity detector (21). The levels are transmitted wirelessly to the fluid manager (15) by data transfer devices (25). Each data transfer device (25) also supplies power to its allocated secretion quantity detector (21) by means of a battery. The data transfer device (25) can be set to a standby state of low power consumption to save battery power. It is awaken by a signal of the fluid manager (15) and set to the transmitting state.
A fluid counterbalancing system comprising at least one controllable fluid supply device (10) for supplying liquid to a patient (P), at least one receptacle (20a, 20b, 20c) for receiving body secretion of the patient, the receptacle including a receiving container (22) and a secretion quantity detector (21), and a fluid manager (15) controlling the fluid supply device (10), the fluid manager being operatable to establish a quantitative balance of the patient on the basis of the fluid quantities fed by the fluid supply devices (10) and the fluid quantity drained into the receiving container, wherein the secretion quantity detector (21) is provided with a battery-operated mains-independent data transfer device (25) wirelessly communicating with the fluid manager (15) and informing it on the respective measured value detected by the secretion quantity detector.
