Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a mobile X-ray apparatus equipped with a movable carriage having a main wheel and a free wheel attached to the bottom and moving to a patient's room, etc. for X-ray photography, and is particularly convenient for X-ray photography in a patient's room. The present invention relates to a mobile X-ray apparatus equipped with a simple X-ray tube supporter (hereinafter referred to as an arm).

[0002]

[Prior Art]

 As shown in FIG. 5, a conventional mobile X-ray apparatus of this type includes a movable carriage 3 having a main wheel 1 and a free wheel 2 attached to the bottom thereof, and an X-ray high voltage generator mounted on the movable carriage 3. And an X-ray tube supported by an apparatus body 4 accommodating an X-ray control device and the like, and an arm 6 swinging up and down only in the forward direction of the moving carriage 3 on the upper end of a column 5 standing upright on the front of the moving carriage 3. And device 7. Such a device has a good forward field of view when traveling, but the length of the carriage is long, and the X-ray tube device 7 is stored in a position close to the floor.

[0003]

[Problems to be solved by the device]

 However, in such a conventional mobile X-ray apparatus, as shown in FIG. 5, when X-ray imaging is performed in a patient's room, the alignment, especially the imaging distance is adjusted. If you want to move a little horizontally (horizontally) while keeping the height as it is, you must move the moving carriage 4. On the contrary, when changing the height while keeping the horizontal (horizontal) position, there is a problem that the horizontal position that is aligned with the bending angle moves again. Moreover, the moving carriage 4 is laid parallel to the bed. When shooting from the side (see Fig. 4) The arm 6 does not rotate, so the moving carriage must always be positioned from the direction perpendicular to the bed, and the luggage of the patient placed under the bed, etc. It was an obstacle and took a lot of time and effort to position. Further, since the conventional X-ray tube device 7 is stored in front of the moving carriage 3, the carriage length becomes long, and the X-ray tube device 7, which is the heart of the device, may hit the wall or the like.

Therefore, the present invention has an object to solve such a problem and to provide a mobile X-ray apparatus which can be quickly and easily positioned in a patient's room and which secures a forward field of view.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, a mobile X-ray apparatus according to the present invention comprises a mobile carriage having a main wheel and a free wheel attached to the bottom thereof, an X-ray high voltage generator and an X-ray control unit mounted on the mobile carriage. In the mobile X-ray apparatus, the mobile X-ray apparatus is provided with an apparatus main body accommodating the apparatus and the like, and an X-ray tube device supported by an arm that is flexibly connected to the front of the movable carriage in a dogleg shape. A bearing that can rotate in a horizontal plane is provided at the front of the carriage, and an arm that is bent in a dogleg shape and connected by two supporting members is erected on this bearing. The bearing provided on the front part of the moving carriage is provided with a contact for limiting the refraction angle only when the supporting member below the dogleg arm turns to the side of the moving carriage. With this structure, the X-ray tube device can be stored in the upper part of the cart on the hand-pushed side.

[0006]

[Action]

 When the movable X-ray apparatus configured in this way is positioned by the rotation-existing dog-legged arm provided at the front part of the moving carriage, the whole movement of the dog-legged arm depends on the movement. There will be no significant height or lateral misalignment. In addition, to take an image from the side of the bed, the entire doglegged arm can be turned to the side. Also, when traveling, it can be stored lower by turning further to the push side. Therefore, the length of the carriage can be shortened.

[0007]

【Example】

 Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a perspective view showing a mobile X-ray apparatus according to an embodiment of the present invention. In the figure, a moving carriage 3 serves as a base member on which an apparatus main body 4, an X-ray tube device 7 and the like, which will be described later, are placed and moves, and large-diameter wheels 1 are attached to the left and right sides of its bottom. At the same time, a swingable wheel 2 is attached to the front of the bottom.

A device body 4 is mounted on the upper surface of the movable carriage 3. The apparatus main body 4 applies a high voltage to an X-ray tube device 7 to be described later to emit X-rays and controls an imaging operation of an imaging region of a patient (not shown). The device, X-ray controller, battery, etc. are stored. A lateral bar-shaped hand-pushing handle 8 is provided at the upper rear portion of the apparatus main body 4, and the operator 9 grips and pushes the hand-pushing handle 8 to move the movable carriage 3. It is like this.

A bearing 10 that can rotate in a horizontal plane is provided in the front part of the moving carriage 3, and both ends of a first arm 11 that is erected on the bearing 10 are rotatable, and a lower end thereof is a bearing. The upper end of 10 is rotatably connected to the second arm 12. Further, an X-ray tube device 7 is supported on the upper end of the second arm. Although not shown, the first arm 11 and the second arm 12 have a built-in balance mechanism (not shown) for balancing the weight of the X-ray tube device 7 with a spring or the like. The bearing 10 provided in the front part of the moving carriage 3 has a structure in which the first arm 11 can largely make an angle in the longitudinal direction of the moving carriage 3 but can limit the angle in the lateral direction of the moving carriage 3. There is.

Here, in the present invention, first, for the X-ray imaging when the vehicle is positioned at a right angle to the bed, the moving carriage 3 is set substantially in the vicinity of the bed, and the X-ray tube device 7 is positioned above the patient. By using the bending and stretching of the first arm 11 and the second arm 12, the height can be adjusted to the left and right with a substantially constant height. Further, it can be adjusted by bending and extending the first arm 11 and the second arm 12 at a substantially constant lateral position (FIG. 3).

Next, when the X-ray image is taken from the side of the bed, the movable carriage 3 is positioned parallel to the bed, the X-ray tube device 7 is rotated to above the bed, and the same operation as described above is performed. Good. However, when the X-ray is taken from the side direction, the width of the carriage 3 is limited, so if the same bending and stretching (maximum extension of the X-ray tube device 7) as in the front-back direction is performed, the entire device may fall. Therefore, the inclination of the first arm 11 is limited (FIG. 4). When traveling, the X-ray tube device 7 together with the first arm 11 and the second arm 12 is turned to the front hand handle 8 side of the moving carriage 4, and the X-ray tube device 7 is housed in the recess 13 formed in the main body 4, and when traveling Has good forward visibility.

In the above description, the manual operation is basically explained, but the present invention is not limited to this, and the movement of each arm may be electrically operated by electric power or another noise source. Also, the traveling of the moving carriage 3 may be performed by using the main wheels 1 as a power source using a noise source such as a motor.

[0014]

【The invention's effect】

 Since the present invention is configured as described above, the dogleg-shaped arm provided on the front portion of the moving carriage 3 has the first arm 11 and the second arm 12 which rotate in the horizontal plane to form the dogleg-shaped arm. Since it bends and stretches, the phenomenon that the lateral direction changes or vice versa can be solved by changing the height, which was the conventional defect. Further, since the X-ray tube device 7 can be turned to the side direction of the moving carriage 4 which is a drawback of the prior art, the operability is further improved. Further, since the X-ray tube device 7 can be stored on the side of the push handle 8 of the dolly, the length of the moving dolly 3 is short, and the X-ray tube device is stored in the recess 13, so that the posture at the time of traveling is low, so that the front view is reduced. Since it is possible to maintain good safety, it is possible to secure safety when traveling in a narrow hospital corridor.
