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.

Claims

1. A hydration management system comprising:

a console for mounting on an IV pole;

a first attachment extending from the console for hanging a urine collection bag;

a first weighing device in the console responsive to the first attachment for weighing the urine collection bag;

a second attachment extending from the console for hanging a source of hydration fluid in an infusion bag;

a second weighing device in the console responsive to the second attachment for weighing the infusion bag;

an infusion pump integrated with the console and configured to pump hydration fluid from the infusion bag;

a controller in the console, responsive to the first and second weighing devices, and configured to control the infusion pump to hydrate the patient based on the patient'"'"'s urine output;

an infusion set connected to the infusion bag and including an IV needle connector; and

a urine collection set connected to the urine collection bag and including a catheter connector; and

a system priming set having;

a connector configured to receive the IV needle connector of the infusion set, and

an adapter for connection to the connector and configured to receive the catheter connector of the urine collection set to drive hydration fluid in the infusion bag into the urine collection bag.

2. The system of claim 1 in which the infusion set further includes a check valve between the IV needle connector and an infusion bag connector to prevent gravity flow of infusion fluid into the patient.

3. The system of claim 1 in which the infusion set and the urine collection sets are coded.

4. The system of claim 3 further including a map depicting the proper installation of the coded infusion and urine collection sets.

5. The system of claim 1 in which the infusion set further includes a pressure transducer leg for interconnecting infusion set tubing to a pressure transducer on the console.

6. A patient connection system for a balanced hydration unit, the system comprising:

an infusion set extending from an infusion bag to a patient IV needle and including;

an infusion bag connector,

an IV needle connector, and

tubing extending between the infusion bag connector and the IV needle connector;

a urine collection set extending from a patient catheter to a urine collection bag and including;

a urine collection bag connector,

a catheter connector, and

tubing extending between the urine collection bag and the catheter connector; and

a priming set configured to connect the IV needle connector of the infusion set to the catheter connector of the urine collection set to drive infusion fluid from the infusion bag into the urine collection bag before connection of the infusion set and the urine collection set to the patient.

7. The system of claim 6 in which the IV needle connector is a luer connector and the catheter connector is a Foley catheter connector.

8. The system of claim 6 in which the priming set includes:

a luer connector configured to receive the luer connector of the infusion set, and

an adapter connected to the luer connector and configured to receive the catheter connector of the urine collection set.
