Abstract

A liquid medicine injection device is controlled by a controller. The liquid medicine injection device includes: a liquid medicine injection unit; a first communication unit which communicates with the controller; and a control unit which switches off the communication by the first communication unit while the liquid medicine injection unit is injecting a liquid medicine. Communication between the liquid medicine injection device and the controller is carried out securely.

Claims

1. A liquid medicine injection device controlled by a controller, the device comprising:

a liquid medicine injection unit;

a first communication unit which communicates with the controller; and

a control unit which switches off the communication by the first communication unit while the liquid medicine injection unit is injecting a liquid medicine.

2. The liquid medicine injection device according to claim 1, wherein

the first communication unit transmits information that gives an instruction to switch off the communication, to the controller.

3. The liquid medicine injection device according to claim 1, wherein

the first communication unit transmits an off-time of the communication to the controller in the case where a liquid medicine injection is started.

4. The liquid medicine injection device according to claim 3, wherein

the control unit switches off the communication in the case of starting a liquid medicine injection and switches on the communication after the liquid medicine injection is finished.

5. The liquid medicine injection device according to claim 1, further comprising

a notification unit which, when an abnormality in the liquid medicine injection device occurs while the communication is off, gives a notification of the occurrence of the abnormality.

6. The liquid medicine injection device according to claim 1, comprising

an operation unit which accepts an operation to stop the injection of the liquid medicine.

7. The liquid medicine injection device according to claim 3, wherein

the off-time is a time period including a time period of one or more continuous liquid medicine injections,

the first communication unit receives a setting of a length of the off-time from the controller, and

the control unit decides the length of the off-time on the basis of the setting.

8. The liquid medicine injection device according to claim 3, wherein

the device operates using a battery as a power source,

the off-time is a time period including a time period of one or more continuous liquid medicine injections, and

the control unit decides a length of the off-time according to a remaining capacity of the battery.

15. A liquid medicine injection system comprising:

the liquid medicine injection device according to claim 1; and

a controller which controls the liquid medicine injection device;

wherein the controller includes a second communication unit which communicates with the liquid medicine injection device.

9. A controller for controlling a liquid medicine injection device, the controller comprising:

a second communication unit which communicates with the liquid medicine injection device; and

a control unit which switches off the communication by the second communication unit while the liquid medicine injection device is injecting a liquid medicine.

10. The controller according to claim 9, wherein

the second communication unit receives information that gives an instruction to switch off the communication, from the liquid medicine injection device, and

the control unit switches off the communication if the information that gives the instruction to switch off the communication is received.

11. The controller according to claim 9, wherein

the second communication unit receives an off-time of the communication from the liquid medicine injection device, and

the control unit switches off the communication during the off-time and switches on the communication after the off-time.

12. The controller according to claim 11, comprising

an operation unit which accepts a setting of a length of the off-time,

wherein the second communication unit transmits the setting to the liquid medicine injection device.

13. The controller according to claim 10, comprising

a notification unit that notifies that the communication is shifted to an off-state or returned to an on-state.

14. The controller according to claim 10, comprising:

an operation unit which accepts a setting of the liquid medicine injection device; and

a notification unit which notifies that the communication is in an off-state if the setting of the liquid medicine injection device is accepted while the communication is off.

16. A liquid medicine injection system comprising:

the controller according to claim 9; and

a liquid medicine injection device controlled by the controller;

wherein the liquid medicine injection device includes

a liquid medicine injection unit, and

a first communication unit which communicates with the controller.

17. A control method for a liquid medicine injection device which communicates with a controller, the method comprising:

switching off the communication with the controller while the liquid medicine injection device is injecting a liquid medicine.
