1. A medical fluid injection system for a plurality of patients, the medical fluid injection system comprising:
a plurality of medical fluid injection devices for the plurality of patients, respectively;
an external device for giving an instruction to start a medical fluid injection and an instruction to stop the medical fluid injection to the plurality of medical fluid injection devices, the external device being outside the plurality of medical fluid injection devices; and
a communication module,
wherein each of the plurality of medical fluid injection devices includes a pump for supplying the medical fluid, a communication part, a pump control part, a storage part, and a module detection part,
wherein the communication part is configured to receive:
a start signal outputted from the external device including the instruction to start the medical fluid injection;
a start inputter signal outputted from the external device, the start inputter signal carrying start inputter information for identifying a start inputter who executes a start input to the external device including the instruction to start the medical fluid injection;
a stop signal outputted from the external device including the instruction to stop the medical fluid injection; and
a stop inputter signal outputted from the external device, the stop inputter signal carrying stop inputter information for identifying a stop inputter who executes a stop input to the external device including the instruction to stop the medical fluid injection,

wherein the pump control part is configured to control the pump to start the medical fluid injection when the communication part receives the start signal, and stop the medical fluid injection when the communication part receives the stop signal,
wherein the storage part is configured to store the start inputter information together with start instruction information indicating that the instruction to start the medical fluid injection is given, and the stop inputter information together with stop instruction information indicating that the instruction to stop the medical fluid injection is given,
wherein the communication module is configured to receive the start signal or the stop signal which is outputted from the external device;
wherein the communication module includes:
a connecting part for connecting the communication module to one of the plurality of medical fluid injection devices; and
a module communication part configured to transmit, to the one of the plurality of medical fluid injection devices, the start signal or the stop signal which is inputted to the communication module from the external device,

wherein the module detection part is configured to detect that the communication module is capable of communicating with the one of the plurality of medical fluid injection devices when the communication module is connected to the one of the plurality of medical fluid injection devices such that the communication module is positioned at a predetermined location of the one of the plurality of medical fluid injection devices,
wherein the one of the plurality of medical fluid injection devices includes a display part for displaying that a state where the one of the plurality of medical fluid injection devices and the communication module are able to communicate with each other is established,
wherein the communication part of the one of the plurality of medical fluid injection devices is configured to receive the start signal and the stop signal only by communication with the communication module, and
wherein the one of the plurality of medical fluid injection devices is configured not to start the medical fluid injection, not to stop the medical fluid injection, and not to change a set value for the medical fluid injection by itself after the communication module is disconnected from the one of the plurality of medical fluid injection devices.
