Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention is applicable to medical applications such as an X-ray CT device, an X-ray diagnostic device, a magnetic resonance imaging device, a nuclear medicine device, or a radiation medical device. The present invention relates to a bed provided in a diagnostic device, and particularly relates to a technology for expanding the functions of a top plate provided in a bed.

(Prior Art) This type of medical diagnostic device, such as an X-ray CT device or a nuclear magnetic resonance imaging device, has a structure based on its principle.
Some cameras have a shooting space formed inside the dome. The subject is placed on the top plate of a bed device attached to this gantry dome, and by sliding this top plate in the longitudinal direction, the part to be imaged is inserted into the imaging space,
It will be photographed. At this time, the head or legs are placed on the end of the top plate on the gantry dome side, depending on the region to be photographed.

When the subject's head is placed on the end of the top plate on the side of the gantry dome, a headrest is attached to the end of the top plate for fixing the head. At this time, if the subject is tall, a foot support may be attached to the end of the top plate on the opposite side to place the feet. In this way, the headrest and foot supports can be removably attached to the top plate, taking into consideration the body part to be photographed and the height of the subject. Furthermore, since body movements of the subject during imaging can cause artifacts, the headrest and foot supports are firmly attached to the top plate.

(Problem to be solved by the invention) However, since the body parts to be imaged and the height of each subject vary, there are many opportunities to put on and take off the headrest and foot support as described above. i on the sleeper device! They are stored in a specific storage space that is separate from the bed so that they do not get in the way during installation, so they must be taken in and out of this storage space each time they are attached, removed, or replaced, and must be firmly attached to prevent them from coming loose. It was a huge burden in terms of time and effort. Also, securing space in the storage compartment was a hassle.

The present invention has been made in view of the problems of the prior art, and provides a bed for medical diagnosis that can eliminate the trouble of attaching accessory parts such as a headrest and foot support, and can also omit the storage space for these accessory parts. The purpose is to provide

[Structure of the invention]

(Means for Solving the Problems) In order to solve the above problems and achieve the objects, the medical diagnosis bed according to the present invention is capable of being raised freely by a rotating shaft member provided at the longitudinal end of the top plate. It is equipped with an auxiliary member that is pivotally supported by the top plate, and is incorporated into the top plate before being raised, on which a part of the subject, for example, the head or legs, can be placed when raised.

(Function) According to this configuration, the auxiliary member is raised depending on the body part to be photographed and the height of the subject, and the headrest on which the subject's head is placed and the bile part are placed. It is now possible to use the top plate as a foot support, or push it back and use the top plate in the same state as when accessories such as headrests and foot supports are removed, and attachment and detachment of accessories can be done as before. There will be no need. Also,
Since the accessory parts are incorporated into the top plate when not in use, the storage space for the accessory parts can be omitted.

(Example) Hereinafter, an example in which the bed for a medical diagnostic apparatus according to the present invention is applied to an X-ray CT apparatus will be described with reference to FIGS. 1 and 2.

FIG. 1 is a diagram showing a schematic configuration of an X-ray CT apparatus.

This X-ray CT apparatus is equipped with a gantry 1 and a bed device 2. In the pedestal 2, an unillustrated Xi tube and an X-ray detector are arranged to face each other with an imaging space 3 formed therebetween. This X-ray tube rotates around the center of the imaging space and irradiates X-rays in a fan shape toward an X-ray detector which also rotates around the center of the imaging space. The signal obtained by the X-ray detector is
Processing such as amplification and integration, digital conversion, and single image reconstruction are performed, and the contents of the processing results are displayed as images on a monitor such as a CRT (not shown).

On the other hand, on the upper surface of the bed device 2, a top plate 5 and a maturo, which will be described later, are provided. By placing the subject P on this celestial body 5 via the maturo and moving it along its longitudinal direction, an arbitrarily set scan region of the subject P can be placed in the imaging space 3 of the mount l. It is said that

As shown in FIGS. 2(a) and 2(b), the top plate 5 is provided with a headrest 7 and a font support 8 at each of its longitudinal ends. These hendless doors and doors.

Each of the support supports 8 is pivotally supported on the top plate 5 by a shaft member 9 and a shaft member 1o provided in the transverse direction of the top plate 5, and these shaft members 9 and 1o are used as rotational axes to rotate the top plate 5 in the longitudinal direction. It can be freely pulled outward. The angle at which this is pulled up is 180' for the foot support 8.
The headrest 7 can be adjusted to any angle up to 180°. In order to be grasped during such lifting, the headrest 7 and the foot support 8 are provided with a protrusion 12 and a protrusion 13 that protrude in the lateral direction of the top plate at two locations on the opposite end of the pivoted one. is provided.

Furthermore, openings 14.15 are provided in the top plate 5 so that the headrest 7 and the foot support 8 can be inserted thereinto so as to correspond to the shapes of the headrest 7 and the foot support 8, including the projections 12.13. . The lower surface of the headrest 7 before being raised is curved to match the head PH of the subject 2, but the upper surface is flat, and the upper and lower surfaces of the foot support 8 are flat. Therefore, before both are raised, the top plate 5 is formed into a substantially --shaped plane.

In addition, a cloak 6 is provided to cover almost the entire upper surface of such a top plate 5, and this cloak 6 opens an opening that is opened when the hendless door or foot support 8 is raised. The opening 15 will be closed. In other words, since the width of the headrest 7 is about 200+ms, the cloak 6 can be occluded to the extent that the top plate 5 does not have any rigidity, but does not cause any problem at the pH of the subject.

On the top plate 5 of such an XgCT apparatus, the subject P
Depending on the part to be photographed and height, etc., lift the Mafutoro and raise the necessary headrest 7 or foot support 8, then place the Mafutoro again and place the Mafutoro on each side. 'H or leg part PF 1322Z, or conversely, the headrest 7 or foot support 8 can be pushed back and the top plate 5 can be used with no attached parts attached.

Therefore, with such a top plate 5, compared to using a conventional removable headrest or foot support, the effort of going to the storage to pick up the headrest or foot support and the effort of putting on and taking it off can be saved. Therefore, it is possible to save setting time before shooting. Also,
Since the headrest 7 and the foot support 8 can be fitted into the opening 14 or the opening 15 and built into the top plate 5 when not in use, there is no need to secure a storage space for the headrest 7 and the foot support 8.

At the same time, there is no need to prepare accessory parts such as a removable heel lift support, and the structure of the accessory parts can be simplified.

[Effects of the Invention] As explained above, in the bed for a medical diagnostic device according to the present invention, the bed for a medical diagnostic device according to the present invention is pivotably supported by a rotary shaft member provided at the longitudinal end of the top plate so that it can be raised freely. The device is configured to include an auxiliary member that is incorporated into the top plate and allows a part of the subject, such as the head or legs, to be placed in the R position when raised.

Therefore, according to such a configuration, the auxiliary member is raised according to the most shadowed part of the subject and his/her height.
The headrest and legs on which the subject's head is placed are R'l.
It is now possible to use the top plate as a foot support, or push it back and use the top plate in the same state as when accessories such as headrests and foot supports have been removed. disappears.

Further, since the accessory parts are incorporated into the top plate when not in use, the storage space for the accessory parts can be omitted.
