Abstract

A hydration management system includes a console for mounting on an IV pole. A urine collection bag and a hydration fluid bag hang from the console. Urine in the urine collection bag is weighed. An infusion pump is configured to pump hydration fluid from the infusion bag. A controller is responsive to the weight of the urine collection bag and controls the infusion pump to hydrate the patient based on the patient'"'"'s urine output. An infusion set includes an infusion bag connector, an IV needle connector, and tubing, placed in the infusion pump, extending between the infusion bag connector and the IV needle connector. A urine collection set typically includes the urine collection bag, a catheter connector, and tubing extending between the urine collection bag connector and the catheter connector.
