[Detailed description of the invention]

[0001]

The present invention relates to an X-ray CT apparatus and an MRI.
The present invention relates to a medical device such as a device.

[0002]

2. Description of the Related Art In a conventional medical apparatus, a top plate on which a patient is placed for examination or the like is connected to a driving device via a clutch. Then, a changeover switch for changing the top plate from automatic to manual was connected to the clutch.

[0003] In the examination room, the technician places the patient on the tabletop, depresses the changeover switch, disengages the clutch, manually operates the patient, and sends the patient into the gantry. Press the switch again to engage the clutch, fix the top board, move to the operation room, and perform operations related to scanning at the console.

[0004]

[Problem to be solved by the invention] At this time, if the user forgets to fix the top plate, after performing an operation related to scanning,
For example, an error is displayed to inform the user of forgetting to fix the top plate.
And the engineer noticed that the top plate was not fixed,
He had to move to the examination room, press the switch to fix the tabletop, and return to the operation room to perform scan-related operations.

[0005] The present invention solves the above-mentioned problems and provides an automatic top plate.
It is an object of the present invention to provide a medical device that can receive a top plate operation signal and return the changeover switch to a normal state even when the operation of the manual changeover switch is forgotten.

[0006]

Means for Solving the Problems To solve the above problems, the configuration of the present invention is as follows. In a medical device to which an automatic / manual changeover switch of a top board is connected, the changeover switch is connected to a driving device via a controller,
When the changeover switch is in a manual (free) state of the top panel, a top panel fixing signal is sent to the driving device in accordance with a command regarding scanning from the operation room.

[0007]

Normally, the driving device is ON, the driving device is connected to the top driving system, and when a switch on the operation panel is pressed, the controller drives the driving device to move the top plate. When the changeover switch is pressed, the controller turns off the driving device, the top plate driving system is disconnected and the fixing is released, and the top plate can be manually moved. When the console issues a scan-related command to the controller in the unlocked state, the controller sets the drive to O.
N, the top is fixed.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to an embodiment shown in the drawings. In FIG. 1, a top plate 1 of a medical device is connected to a driving device, which is a clutch 2,
It comprises a motor 3 and a driver 4. The changeover switch 7 is connected to the controller 5, and sends a top plate fixing signal to the clutch 2 when the changeover switch 7 is in the top plate moving state in accordance with a command related to scanning from the operation room.

The operation state will be described above. In FIG. 1, the clutch 2 is normally turned on and the motor 3 is turned on.
And the top drive system 1a are connected, and when a switch on an operation panel (not shown) is pressed, the controller 5
Drives the motor 3 to move the top board 1. When the changeover switch 7 is pressed, the controller 5 turns off the clutch 2, the top plate drive system 1a is disconnected and the fixing is released, and the top plate 1 can be moved manually. When the console 6 outputs a command related to scanning to the controller 5 in a state where the locking is released, the controller 5 turns on the clutch 2 and the top board 1 is fixed.

Here, the commands related to scanning from the console 6 are, for example, commands for rotating the tube, tilting the gantry, sending in and pulling out the top plate, and are not shown. Also controls them, which are well-known techniques.

The controller 5 has a microprocessor mounted thereon, and reads a signal from the changeover switch 7 to control power to the clutch 2. For example, the power is turned on by the microprocessor controlling the signal.
/ OFF.

The above operation will be described with reference to the flowchart of FIG. In step 1, it is determined whether or not the changeover switch 7 has been pressed. If so, it is determined in step 2 whether the top control is automatic or manual.
Power. If the top control is automatic, the power supply to the clutch 2 is stopped in step S5. Also, the changeover switch 7
If is not pressed, power is supplied to the clutch 2 in step 4.

As another embodiment of the present invention, when a stepping motor is used as the motor 3, it can be implemented without using a clutch as shown in FIG. That is, the stepping motor can hold itself when the power is turned on and cannot be held when the power is turned off. Therefore, when the top plate 1 is fixed, the controller 5 turns on the relay 8 and the stepping motor 3
To supply power to the top plate and make the top plate free.
Is turned on to turn off the power to the stepping motor.

In the flowchart (not shown), a relay is operated instead of the clutch in the case of the clutch (FIG. 2). The description is omitted because it is substantially the same as FIG.

The present invention is not limited to the above-described embodiments and embodiments, but includes various modifications without departing from the spirit and scope of the utility model registration request.

[0016]

[Effect of the Invention] According to the configuration of the present invention, even if the technician forgets to fix the top plate after the technician puts the patient in a manual state before the examination and prepares the patient, the technician will not be aware of the top plate. It is fixed automatically and the inspection can be started. This greatly reduced the technician's effort.
