1. An IV line management apparatus for intravenous administrations of multiple solutions comprising:
a housing for receiving a piggyback tubing assembly comprising a primary IV tube from a primary solution IV bag as joined to a secondary IV tube from a secondary IV solution bag with a joining-connector and an exit tube passing from the joining-connector;
first and second metering clamps engaging the primary IV tube and secondary IV tube respectively when the piggyback tubing assembly is received within the housing for controlling flow through the primary IV tube and secondary IV tube according to electrical signals received by the first and second metering clamps;
at least one flow rate sensor sensing flow through the piggyback tubing assembly; and
a controller comprising an electronic computer executing a stored program and receiving at least one signal from at least one flow rate sensor and providing electrical signals to the first and second metering clamps according to the stored program.
2. The IV line management apparatus of claim 1 wherein the electronic computer executes the stored program to control the first or second metering clamps to limit flow through the flow rate sensor to a predetermined maximum value.
3. The IV line management apparatus of claim 1 wherein the electronic computer executes the stored program to provide electrical signals to the first and second electrical metering clamps in a first state to stop flow through the primary IV tube while allowing flow through the secondary IV tube until a flow rate lower than a second predetermined value is detected and then to provide electrical signals to the first and second electrical metering clamps in a second state to stop flow through the secondary IV tube while allowing flow through the primary IV tube.
4. The IV line management apparatus of claim 3 further including an alarm enunciator for indicating a transition between the first and second states.
5. The IV line management apparatus of claim 1 wherein the first and second metering clamps provide opposed jaws fitting about the primary IV tubing and secondary IV tubing and wherein the electrical signals to the first and second metering clamps control a separation of the jaws in pinching off the primary IV tubing or the secondary IV tubing.
6. The IV line management apparatus of claim 5 wherein the electrical signals to the first and second metering clamps control a separation of the jaws in pinching off the primary IV tubing or the secondary IV tubing to multiple different separations within a range of separations to provide control between a fully open and fully closed separation.
7. The IV line management apparatus of claim 1 further including an electrical switch operator positioned on the housing near the primary IV tubing and secondary IV tubing and wherein the controller executes a stored program to respond to an operator actuation of a switch operator near one of the primary IV tubing and secondary IV tubing to cause a pinching off of alternate ones of the primary and secondary IV tubes depending on the operator actuated.
8. The IV line management apparatus of claim 1 further including display elements positioned on the housing near the primary IV tubing and secondary IV tubing and communicating with the controller to indicate a state of flow through the primary IV tubing and secondary IV tubing.
9. The IV line management apparatus of claim 8 wherein the display elements may be lamps of different colors indicating a state of flow as one of: open, closed, and metered.
10. The IV line management apparatus of claim 9 wherein the lamps provide the colors and organization of a standard traffic light.
11. The IV line management apparatus of claim 1 wherein the housing further includes additional sensors sensing solution in the primary and secondary IV tubing, the sensors selected from the group consisting of: air-in-line sensors, pressure sensors, and tubing-in-place sensors.
12. The IV line management apparatus of claim 1 wherein the flow rate sensor is selected from the group consisting of a drip chamber, a turbine, and a thermal time-of-flight sensor.
13. The IV line management apparatus of claim 1 wherein the housing includes a cover closing over the piggyback tubing assembly when received within the housing to retain the tubing within the housing.
14. The IV line management apparatus of claim 13 wherein the cover includes a window positioned to allow visual inspection of the tubing.
15. The IV line management apparatus of claim 14 further including a lock for holding the cover closed against the housing.
16. The IV line management apparatus of claim 1 wherein the joining connector is a Y-connector.
17. An IV line management apparatus for intravenous administrations of multiple solutions comprising:
a housing for receiving a tubing assembly comprising multiple inlet IV tubes connecting to corresponding different solution IV bags as joined by a multi-way connector leading to an exit tube passing from the multi-connector;
metering clamps engaging the each of the multiple inlet IV tubes when the tubing assembly is received within the housing for independently controlling flow through each of the multiple inlet IV tubes according to electrical signals received by the metering clamps;
at least one flow rate sensor sensing flow through the tubing assembly; and
a controller comprising an electronic computer executing a stored program and receiving at least one signal from at least one flow rate sensor and providing electrical signals to the metering clamps according to the stored program.
The claims below are in addition to those above.
