Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an X-ray imaging device, and particularly to a cassette-less X-ray imaging device.

[Conventional technology]

As shown in FIG. 3, this type of X-ray imaging apparatus includes an X-ray control unit 60 that controls X-rays, and automatically sets X-ray film in a position where it can be taken and stores the film that has been taken into a magazine. A video installation using the cassette-less method! 62, an imaging device 63 consisting of a tomography device or a fluoroscopic table device and having an X-ray tube, and a control device 61 that controls both the cassette-less type imaging device 62 and the imaging bag f163.

Among these, the control device 61 usually includes a plurality of photographing devices 6.
3, the X-ray control unit 60 connects to each of the X-ray tubes of the plurality of imaging devices 63
It has a so-called dual selection function that allows selection and control of one of the wire tubes. The X-ray control section 60 is equipped with a dual-type selection push button 66 as a means for operating such a function that allows selection of both types.

Here, for example, three imaging devices are connected to the X-ray control section 60, one of which is a tomography device, and the tomography device is the imaging device shown in FIG. 3!
63.

Said Xi! Let us consider a case where, after turning on the power switch 67 of the control unit 60, the tomography apparatus is selected using the dual selection push button 66.

When the both type selection push button 66 is turned on, the electromagnetic contactor 50 is turned on. This electromagnetic contactor 5
0 turns on, relays 52, 53, and 54 all turn on.

At this point, the photographing device 63 is supplied with power and becomes operational. Further, when the relay 52 is turned on, the electromagnetic contactor 55 is turned on. When this electromagnetic contactor 55 is turned on, relays 56 and 57 are turned on. At this point, power is supplied to the control device 61 and the video device 62 and they become operational.

As a result, control signals 64 are sent from the control device 61 to the video device 62 and the photographing device 63, respectively. This control signal 64 causes the video device 64 to
Then, take out the X-ray film from the magazine, insert it into the film holder via the conveyance path, move the film holder to a position where photography is possible, and store the film in the film holder in the magazine when photography is finished. It looks like this. For this reason, the video device 62 is provided with a plurality of actuators and sensors for automatically operating these devices. Further, the photographing device 63 is configured to perform various tomographic trajectories and change the five cutting planes. Such operations are performed using, for example, an operation console (not shown) on the XvA control section 60.

Note that if you want to use the X-ray control unit 60 to transfer the dual-type selection from the conventional tomography device W63 to another imaging device, or if you want to turn off the power,
The electromagnetic contactor 50 will be turned off. By turning off this electromagnetic contactor 50, the relays 52, 53
, 54 are both turned off. At this point, the photographing device 63 is no longer supplied with power, and therefore becomes inoperable. Further, since the relay 52 is turned off, the relays 56 and 57 are turned off. Said control device at this point! 61 and the video device 62 are no longer supplied with power and similarly become inoperable.

[Problem to be solved by the invention]

For this reason, in conventional X-ray imaging equipment, as is clear from the above, when switching between the two types, the power of the imaging equipment that was previously selected is immediately turned off, and as a matter of course, When the power to the X-ray control unit 60 is turned off, power is no longer supplied.

Furthermore, although the cassette telephoto imaging device 62 has the above-mentioned functions, the Xs
The film will automatically retract and will take several seconds to fully retract. In hospitals, there are many patients who undergo X-ray photography, and for this reason, the several seconds mentioned above become extremely wasted time when the operator wants to take X-ray images efficiently.

In addition, the operator selects both methods to take an image using an imaging device with a cassette-type imaging device, and when the imaging is completed, the operator selects the same option to perform a chest scan in order to image the next patient. When switching to the cassette telephoto camera, as mentioned above, even though the film is automatically stored at the same time as shooting ends, power is cut off and the film is not completely stored. It may stop midway. In this case, even if the surgical technique selection is changed again, the control device 61 determines that the film is caught in the middle, causing an error, and the video device 62 stops operating. This means that the film that could not be stored must be removed manually, and since the film that was taken has still been exposed to light, no X-ray image can be obtained even if it is developed. . Therefore, the patient has to lie down on the imaging table for the imaging again and is exposed to extra X-rays, and on the other hand, the operator wastes extra time.

Furthermore, the operator should wait until the film is completely retracted, confirm that the film has been retracted, and then switch the surgical method selection, but since many patients are waiting, These few seconds end up being a huge waste of time.

Furthermore, in conventional X-ray imaging apparatuses, even when the power is turned on and off, the same result as switching the surgical method selection described above is obtained, making it extremely difficult for the operator to operate the apparatus.

Therefore, the present invention was made based on these circumstances, and its purpose is that, despite its simple configuration, it does not work even when the power is turned off or when the surgical method is selected. To provide an X-ray imaging apparatus in which the film can be completely stored or inserted into a film holder even after switching.

[Means to solve the problem]

In order to achieve such an object, the present invention basically provides a cassette-less type imaging device that includes a film transport unit that exchanges film that has been shot and film that has not been filmed;
In the X-ray imaging apparatus, the X-ray imaging apparatus includes an imaging apparatus including an X-ray tube, a control device that controls the imaging device and the imaging device, respectively, and an X-ray control section including a power switch and a surgical procedure selection switch. When the switch is turned on, preparations are made to supply power to the control device and the imaging device, and the surgical technique selection switch is turned on to supply power to the selected imaging device and to the imaging device. Power is supplied on the premise that preparations for power supply are made, and the control device is supplied with power on the premise that power is supplied to the video device and power is supplied to the photographing device. and means for maintaining power supply to the video device.

[Effect]

In the X-ray imaging apparatus configured as described above, first, when the power switch provided in the X-ray control section is turned on, power is supplied to the control device 26. At this time, power is not supplied to the imaging device W28, but preparations for power supply are made.

In this state, if the surgical technique selection switch is used to select both techniques, power will be supplied to the video device 27 corresponding to the selection. At this time, power is also supplied to the photographing device 28.

Next, when the surgical procedure selection is switched to another imaging device other than the imaging device 28, power is not supplied to the imaging device at this point and its operation stops. However, in this case, if the video device 27 is in operation, the control device is provided with a means for maintaining the power supply, so the power remains supplied to the video device. It becomes. Power continues to be supplied to this imaging device until the film is completely stored.

For this reason, despite the simple configuration, the film can be completely stored or inserted into the film holder even if the power is turned off or the surgical method selection is changed.

The film holder 85 is held in the vicinity of the opening in the film holder 85.

As shown in FIG. 1, the power line supplied from the X-ray control unit 25 to each device is X4! A relay 2 that operates by turning on and off the dual selection push button 31 of the control unit 25, a relay 3 that operates by turning on and off a power switch provided in the X-ray control unit 25, and the control device 2.
6 is provided with a relay 1 which operates depending on whether the video device 27 or the photographing device 28 is in operation. Further, relays 10 and 17 are provided which are operated by the relay 2, and these are connected to the video equipment, respectively. 27 and the photographing device i28. Similarly, a relay 6 is provided which is operated by the relay 3 and is associated with the control device 26. Further, relays 5 and 9 operated by the relay l
is established.

The relay 5 is connected in parallel with the relay 6.

Further, the sword 9 is connected in parallel with the relay 10.

An electromagnetic contactor 11 that operates by turning on and off the relays 5 and 6 is connected in series with the parallel connection of the relays 5 and 6. Further, a relay 7.8 is provided which is operated by turning on and off the electromagnetic contactor 11, and this relay 7.8 is involved in the control device 26.

Further, a relay 15.16 is provided which is operated by turning on and off the electromagnetic contactor 11, and this relay 15.16
is involved in the photographing device 28.

Further, an electromagnetic contactor 13 and 14, which operates when the relays 9 and 10 are turned on and off, is connected in series with the parallel connection body of the relays 9 and 10, and which operates when the electromagnetic contactor 12 is turned on and off. and is involved in the video device.

The operation of the X-ray imaging apparatus configured in this manner will be described below.

When the power switch 35 provided in the X-ray control unit 25 is turned on, the relay 3 is first turned on. This ON signal from relay 3 turns on relay 6.

This turns on the electromagnetic contactors 11 connected in series. When the electromagnetic contactor 11 is turned on, the relays 7 and 8 are turned on, and power is supplied to the control device 26. At this time, when the electromagnetic contactor 11 is turned on, the relays 15 and 16 are turned on, but at this point, power is not yet supplied to the imaging device 28, and it is assumed that it is in a state of preparation for power supply. It has become.

In this state, when the two-way selection is switched by the two-way selection push button 31, the relay 2 is turned on. This on signal from relay 2 turns on relay 10 in video device 27, which turns on electromagnetic contactor 12 connected in series. This electromagnetic contactor 12
When the relay 13.14 is turned on, the video device 27 is turned on.
Power will be supplied to. Further, in the photographing device 28, the electromagnetic contactor 20 is turned on when the relay 17 is turned on as the relay 2 is turned on. This electromagnetic contactor 2
0 turns on, relays 18 and 19 turn on, and the photographing device 2
Power is supplied to 8. Furthermore, relays 5 and 9 are turned on by the on signal of relay 1.

Next, consider a case where the two-type selection is switched to another photographing device other than the photographing device 28 shown in FIG.

When the relay 2 is turned off and the relay 10.17 is accordingly turned off by switching between the two types, the photographing device 28 detects that the relay 18.19 is turned off because the electromagnetic contactor 20 is turned off. At this point, power is no longer supplied to the photographing device 28 and its operation is stopped.

However, in this case, the video device 27 side
7 is in operation, the control device 26 is outputting a signal, so the relay 1 is in the on state.

Even if the relay 10 is turned off, the relay 9 connected in parallel with it remains on, the electromagnetic contactor 12 is not turned off, and the relays 13 and 14 are not turned off. Therefore, power continues to be supplied to the video device [27].

This means that, for example, if a photographed film is being stored in the video device 27, power will continue to be supplied until the film is completely stored. The image device 27 is no longer in operation when the film is completely stored, and the signal is turned off in the control device 26, so the relay 1 is turned off, and thereby the relay 9 is also turned off. When the relays 9 and 10 are turned off, the electromagnetic contactor 12 is turned off, so the relays 13 and 14 are turned off, and at this point, the power supply to the video device 27 is stopped.

For this reason, when the two-type selection is switched to OFF, power is immediately no longer supplied to the photographing device 28, but power is not supplied to the control device [26] regardless of the two-type selection. continues to be supplied, and power continues to be supplied to the video device 27 until the operation within the video device 27 is completed.

Further, when the power switch 35 is turned off, the relay 3 is turned off. At this time, the surgical technique selection signal is also turned off, and the relay 2 is turned off. When the relay 3 is turned off, the relay 6 is turned off. However, if the video device 27 is in operation, the relay 1 is in the on state because the operation signal is being sent from the control device, as described above, and even if the relay 6 is off, this is not the case. The relay 5 connected in parallel remains on, so the electromagnetic contactor 11 is not turned off and the relay 7.8 is not turned off. Therefore, even if the power is turned off, power continues to be supplied to the control 26.

Further, even if the both-type selection is turned off, power is still supplied to the video device 27 as long as the video device 27 is in operation as described above, and the photographing device 28 is no longer powered and does not operate. Stop.

Furthermore, when the operation of the video device 27 is completed, power is no longer supplied to the video device 27 and the operation stops.

On the other hand, when the control device 26 is no longer in operation, the relay 1 is turned off, and accordingly the relay 5 is turned off, so the electromagnetic contactor 11 is turned off, and accordingly, the relay 7 is turned off.
．． 8 is turned off, power is no longer supplied and the device no longer operates.

As described above, according to this embodiment, even when the power is turned off or when switching between the two types, the imaging device 28 including the most dangerous X-ray tube immediately stops the power supply and operates. If the video device 27 is in a non-hazardous state and is in operation, power will continue to be supplied until the operation is completely completed, and the device will be automatically turned off when the operation is completed. It's supposed to be.

In the embodiments described above, the present invention is constructed mainly using relays, but it goes without saying that the present invention is not particularly limited to relays, and other switch mechanisms may be used.
