Claims

1. A control system for a liquid infusion apparatus comprising a plurality of liquid infusion devices, each having a common connector of liquid infusion device side for an electric power supply line and a communication line, a plurality of racks stacked one another, each for receiving each of the liquid infusion devices, a plurality of common connectors of rack side, each mounted on each of the racks so as to be connected to each of the common connectors of liquid infusion device side, when each of the liquid infusion devices is inserted into each of the respective racks, a base unit, and a connector provided on the base unit so as to connect an electric power supply line and a communication line to the connectors of rack side.

2. The control system of the liquid infusion apparatus as claimed in claim 1, wherein a network is used for the communication line, and a warning signal is transmitted from any of the liquid infusion devices through the network to the other liquid infusion devices.

3. The control system of the liquid infusion apparatus as claimed in claim 2, wherein when a warning signal is generated in any of the liquid infusion devices in the network and the liquid infusion is stopped, the liquid infusion is carried out by the other liquid infusion device in the network.

4. The control system of the liquid infusion apparatus as claimed in claim 1, wherein when a warning signal is generated in any of the liquid infusion devices in the network and the liquid infusion is stopped, the liquid infusion is carried out by the other liquid infusion device in the network.

5. A control system for a liquid infusion apparatus comprising: an electric power supply line and a communication line;a plurality of liquid infusion devices, each having a common connector on a side thereof for connection to both the electric power supply line and the communication line;a plurality of racks stacked one atop another, each of which receives a respective one of the liquid infusion devices;a plurality of common rack connectors each of which is mounted on a side a respective one of the racks so as to be connected to a respective one of the common connectors of the liquid infusion devices when each of the liquid infusion devices is inserted into each of the respective racks; anda base unit having a connector thereon that is coupled to the common rack connectors and that is connected to the electric power supply line and the communication line.

6. The control system of the liquid infusion apparatus as claimed in claim 5, wherein the communication line comprises a network, and wherein a warning signal transmitted from any of the liquid infusion devices is transmitted through the network to the other liquid infusion devices.

7. The control system of the liquid infusion apparatus as claimed in claim 6, wherein, when a warning signal is generated in any of the liquid infusion devices in the network indicating that the liquid infusion is stopped, the liquid infusion is carried out by at least one of the other liquid infusion devices in the network.

8. The control system of the liquid infusion apparatus as claimed in claim 5, wherein, when a warning signal is generated in any of the liquid infusion devices in the network indicating that the liquid infusion is stopped, the liquid infusion is carried out by at least one of the other liquid infusion devices in the network.
