Abstract

A wireless foot switch according to one embodiment includes a battery unit, a switch unit, a controller, and a state switcher. The battery unit supplies power. The switch unit provides input to an X-ray diagnosis apparatus. The controller transmits by radio, to X-ray diagnosis apparatus, information input by the switch unit. Based on an external signal from the outside of the X-ray diagnosis apparatus, the state switcher causes the controller to transition from a resting state to an operational state.

First claim

What is claimed is:

1. A wireless foot switch comprising:
a battery unit that supplies power;
a switch unit that provides input to an X-ray diagnosis apparatus;
a controller that transmits information to the X-ray diagnosis apparatus by radio, the information having been input by the switch unit; and
a state switcher that, based on an external signal from the outside of the X-ray diagnosis apparatus, causes the controller to transition from a resting state to an operational state.

2. The wireless foot switch according to claim 1 , wherein the state switcher includes a receiver that receives an external signal indicating that the X-ray diagnosis apparatus has become operable for radiating X-rays.

3. The wireless foot switch according to claim 2 , wherein the external signal is at least one signal out of a signal indicating that a door of an examination room inside of which the X-ray diagnosis apparatus radiates X-rays is closed, a signal based on weight acting on a couchtop on which a subject lies, a signal indicating that there is a person in the examination room, and a signal based on light in the examination room.

4. The wireless foot switch according to claim 3 , wherein the signal indicating that there is a person in the examination room is a signal indicating that there is a person near a position where a manipulation is conducted on the subject.

5. The wireless foot switch according to claim 3 , wherein the signal based on light in the examination room is a signal indicating that brightness in the examination room has changed.

6. The wireless foot switch according to claim 1 , wherein, based on an examination start signal in addition to the external signal, the state switcher causes the controller to transition from the resting state to the operating state.

7. The wireless foot switch according to claim 2 , wherein
the receiver receives, as signals indicating that the X-ray diagnosis apparatus has become operable for radiating X-rays, in addition to the external signal, a signal indicating that the X-ray diagnosis apparatus has been operated and a signal indicating that the X-ray diagnosis apparatus is released from a state where radiation of X-rays is disabled, and
the state switcher causes the controller to transition from a resting state to an operational state, based on at least one signal out of the external signal, the signal indicating that the X-ray diagnosis apparatus has been operated, and the signal indicating that the X-ray diagnosis apparatus is released from a state where X-ray radiation is disabled.

8. The wireless foot switch according to claim 2 , wherein the receiver operates by converting part of the external signal into power.

9. An X-ray diagnosis system comprising:
the wireless foot switch according to claim 1 ; and
the X-ray diagnosis apparatus.

10. A wireless foot switch comprising:
a battery unit that supplies power;
a switch unit that provides input to an X-ray diagnosis apparatus;
a controller that transmits information by radio to the X-ray diagnosis apparatus, the information having been input by the switch unit;
a detector that detects an external stimulus; and
a state switcher that, based on the external stimulus, causes the controller to transition from a resting state to an operational state.

11. The wireless foot switch according to claim 10 , wherein the detector detects at least any of vibration, pressure, and contact, as the external stimulus.

12. The wireless foot switch according to claim 10 , wherein, based on an examination start signal in addition to the external stimulus, the state switcher causes the controller to transition from the resting state to the operating state.

13. The wireless foot switch according to claim 10 , wherein, based on at least any of the external stimulus, the signal indicating that the X-ray diagnosis apparatus has been operated, and the signal indicating that the X-ray diagnosis apparatus has been released from a state where X-ray radiation is disabled, the state switcher causes the controller to transition from a resting state to an operational state.

14. An X-ray diagnosis system comprising:
the wireless foot switch according to claim 10 ; and
the X-ray diagnosis apparatus.
