The auxiliary top plate 10 moves in a vertical direction as well according to movement of the moving bridge 7 in the vertical direction by rotation of the driving motor 4.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an X-ray diagnostic apparatus for picking up an X-ray fluoroscopic image of a subject, and more particularly to a technique for facilitating lifting up and down on a bed top.

[0002]

2. Description of the Related Art In recent years, X-ray diagnostic apparatuses have been widely used as medical diagnostic apparatuses have been developed. The X-ray diagnostic apparatus irradiates the subject placed on the bed top with X-rays from the X-ray tube, collects the X-rays that have passed through the subject with an image intensifier such as an image intensifier, and obtains an image. It will be transformed.

In such an X-ray diagnostic apparatus, the bed top is usually about 80 to 90 cm high, and the patient as the subject needs to ride on the top of this height at the time of examination. is there. However, a healthy patient can easily get on the table, but for example, a physically handicapped person cannot easily get on the table. Therefore, attempts have been made to reduce the height of the bed top as much as possible, but since the image intensifier tube and the like are usually arranged inside the bed, it cannot be made lower than a certain height.

[0004]

As described above, the conventional X-ray diagnostic apparatus has a drawback that it is difficult for a person with a physical disability to get on and off because the bed top is at a certain height. It was

The present invention has been made to solve such a conventional problem, and an object of the present invention is to prepare for getting on and off a bed top.
It is to provide a line diagnostic device.

[0006]

In order to achieve the above object, the first invention of the present application is to irradiate a subject placed on a bed top with X-rays and to transmit the X-rays after passing through the subject. In an X-ray diagnostic apparatus that collects X-rays with an image receiver and captures an X-ray image, an elevating device that elevates and lowers a subject up to the height of the bed top is provided.

The second invention of the present application irradiates an object placed on the bed top with X-rays, collects the X-rays transmitted through the object with an image receiver, and obtains an X-ray image. In an X-ray diagnostic apparatus for radiographing, a lead screw which is arranged in a vertical direction inside a bed and in which a spiral thread groove is formed, a rotation driving means capable of reversibly rotating the lead screw, and the lead screw. And a movable member that is screwed together and moves in the vertical direction by the rotation of the lead screw, and an auxiliary top plate that is connected to the movable member and extends to the side of the bed and on which the subject can be placed. Characterize.

[0008]

According to the present invention constructed as described above, the lead screw is rotated by rotating the rotation driving means, and the movable member screwed with the lead screw and the auxiliary top plate connected to the movable member are moved up and down. To do. Then, the rotation of the rotation driving means is controlled and the subject is placed on the auxiliary table with the auxiliary table positioned at the lowest position, and then the auxiliary table is raised to the same height as the bed table. When it comes to Sasa, stop the rise. Then, the subject is moved from the auxiliary top to the bed top side. As a result, the subject can easily get on the bed top.

If a limit switch is provided at the upper end of the lead screw, the lifting is automatically stopped when the auxiliary top reaches the same height as the bed top, so that safety is ensured.

Further, if the auxiliary top plate can be folded to the side surface of the bed, a wide space is not required and the space can be saved.

Embodiments of the present invention will be described below with reference to the drawings. 2A and 2B are configuration diagrams of an X-ray diagnostic apparatus according to an embodiment of the present invention. FIG. 2A is a side view and FIG. 2B is a front view. As shown in FIG. 2, this X-ray diagnostic apparatus has a bed 2 on which a subject is placed, and a bed top plate 3. Above the bed top plate 3, X-rays are directed toward the subject. An X-ray tube 12 for exposure is provided.

An image intensifier tube 13 for detecting the X-rays that have been emitted from the X-ray tube 12 and transmitted through the subject is disposed inside the bed 2. Further, a drive motor 4, a lead screw 6, a movable piece 7 and the like are arranged inside the bed 2. The structure will be described below with reference to FIG. 1 showing FIG. 2A in detail. .

As shown in FIG. 1, a lead screw 6 which is upright in the vertical direction and in which a spiral thread groove is formed is disposed inside the bed 2, and the lead screw 6 is the lowermost portion. Is connected to the pulley 5, and the pulley 5 is connected to the drive motor 4 via the pulley belt 21. Therefore, when the drive motor 4 rotates, this rotational power is transmitted to the lead screw 6 via the pulley belt 21 and the pulley 5, and the lead screw 6 rotates.

Further, the lead screw 6 is provided with a movable piece 7 which is arranged so as to be screwed with the lead screw 6, and the movable piece 7 moves in the vertical direction as the lead screw 6 rotates. . Further, in order to stabilize the vertical movement of the movable piece 7, a rail 8 is provided so as to penetrate the movable piece 7 and substantially parallel to the lead screw 6.

The movable top 7 is connected to an auxiliary top plate 10 through a mounting bracket 9, and the auxiliary top plate 10 is rotated by a hinge 9a of the mounting bracket 9 to form a side surface of the bed 2 as indicated by reference numeral 10a. It can be folded into.

With this structure, the movable top 7 moves in the vertical direction by rotating the drive motor 4, so that the auxiliary top plate 10 also moves in the vertical direction. Therefore, if the auxiliary top plate 10 is located at the bottom, the subject is placed on the auxiliary top plate in this state, and the drive motor 4 is operated to raise the auxiliary top plate 10,
The subject can easily rise to the height of the bed top 3,
It becomes possible to easily get on the bed top 3.

Further, a limit switch 11 is attached to the upper end of the lead screw 6, and when the movable top 7 reaches the upper end, the limit switch 11 detects the approach or contact of the movable top and forces it. Then, the drive motor 4 is stopped. Similarly, a limit switch (not shown) is also provided on the hinge 9a of the mounting bracket 9 so that the interlock with the drive motor 4 can be performed only when the auxiliary top plate 10 is in a horizontal state. Provide a lock mechanism.
This ensures the safety of lifting and lowering the auxiliary top plate.

Further, when the auxiliary top 10 is not used, it can be folded to the side surface of the bed 2, so that a large space is not required. Further, the operation of folding the auxiliary top plate 10 may be manual or automatic.

Further, as shown in FIG. 2A, in this embodiment, two elevating systems including a lead screw 6 and a movable top 7 are arranged. In this case, drive motor 4
One drive motor 4 may be provided with a plurality of pulley belts 21 (FIG. 1) and two drive belts may be provided.
One lead screw 6 may be attached to operate the two lead screws 6.

[0020]

As described above, according to the present invention,
Since the auxiliary couch which can be moved up and down is provided on the side of the couch, the operation for riding on the couch can be significantly facilitated, and it does not impose a heavy burden especially for persons with physical disabilities. Also, when the auxiliary top plate rises, it is stopped at the upper end by the limit switch, so high safety is ensured. Further, since the auxiliary top plate can be folded to the side surface of the bed, it is possible to save space.
