DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a medical device support structure for supporting a medical device on an installation surface.

[0002]

2. Description of the Related Art As a medical device, for example, a stimulable phosphor (stimulable phosphor) is used to temporarily record radiation image information of a subject such as a human body, and this radiation image information is stored in a photograph film or the like. 2. Description of the Related Art There is known a system for reproducing a photosensitive material or the like or outputting a visible image to a CRT or the like.

The stimulable phosphor is composed of radiation (X-ray, α-ray, γ
(Rays, electron beams, ultraviolet rays, etc.), a part of this radiation energy is accumulated, and after irradiation with excitation light such as visible light, a phosphor that emits stimulated emission according to the accumulated energy is referred to. This stimulable phosphor is usually used as a sheet-like stimulable phosphor sheet because of its easy handling.

In the above-mentioned system, for example, a photographing section for temporarily recording radiation image information of a subject on a stimulable phosphor sheet, and irradiating the stimulable phosphor sheet with the radiation image information recorded thereon with excitation light to emit the excitation light. A reading unit that photoelectrically reads the radiation image information, and an erasing unit that erases the radiation image information remaining on the stimulable phosphor sheet after reading the radiation image information are integrally incorporated, and the stimulable phosphor sheet is A so-called built-in type radiation image information reading apparatus (scanning apparatus) that circulates or reciprocates in the apparatus is employed.

Further, a loading section in which a stimulable phosphor sheet preliminarily recording radiation image information of a subject is loaded via a cassette or a magazine, and excitation light is supplied to the stimulable phosphor sheet taken out of the loading section. A radiation image information reading apparatus incorporating a reading unit that photoelectrically reads the radiation image information by irradiating, and an erasing unit that erases the radiation image information remaining on the stimulable phosphor sheet after reading the radiation image information ( Scanning device).

[0006]

Incidentally, the above-described radiation image information reading apparatus employs a structure in which, for example, a reading unit is taken out of the apparatus body as a unit for maintenance or the like. Specifically, as shown in FIG. 8, the radiation image information reading device 1 is installed on a floor surface 2, and is read from a side of an apparatus main body 3 constituting the radiation image information reading device 1 during maintenance. The unit 4 is pulled out in the lateral direction (the direction of arrow A).

However, the above-mentioned reading unit 4 has a relatively large width corresponding to the width of the stimulable phosphor sheet. It will be pulled out by the length. For this reason, it is necessary to separate the apparatus main body 3 from the wall surface 5 by a distance L (for example, about 700 mm) in consideration of workability and the like, which considerably increases the installation space.

As a result, a problem has been pointed out that the radiation image information reading device 1 cannot be effectively installed in a limited space in a hospital. Further, in addition to the above-described radiation image information reading apparatus 1, in various medical devices, the unit is similarly taken out during maintenance. Therefore, in various types of medical equipment, there is a problem that the installation space is considerably expanded and a narrow space cannot be effectively used.

SUMMARY OF THE INVENTION The present invention is to solve this kind of problem, and to provide a medical device support structure capable of effectively reducing the installation space for the medical device and performing maintenance and the like easily and efficiently. With the goal.

[0010]

In the support structure for a medical device according to the present invention, the medical device is usually immovably fixed on an installation surface via a fixing means. Work is taking place. Then, when performing maintenance or the like, the medical device is operated under the action of the rotating device interposed between the installation surface and the medical device in a state where the fixing of the medical device by the fixing device is released. It is rotated to a predetermined angular position. Next, the unit is taken out of the medical device, and a maintenance operation of the unit or the inside of the medical device is performed.

[0011] This makes it possible to arbitrarily change the taking-out direction of the unit only by rotating the entire medical device, and it is possible to effectively reduce the installation space of the medical device. This is because the installation space for the medical device is substantially a rotation space for the medical device.

[0012] The medical device has a unit that can be pulled out in the horizontal direction. Therefore, only by rotating the medical device to a desired angle position, a space for pulling out the unit can be secured, and maintenance and the like of the unit can be easily and efficiently performed.

Further, the medical device is a scanning device for a sheet-shaped recording medium, a sub-scanning conveyance means for sub-scanning and conveying the sheet-shaped recording medium, and a main scanning by irradiating scanning light to the sheet-shaped recording medium. The scanning light irradiating means to be performed is constituted by a single unit, and the unit can be pulled out in the lateral direction with respect to the apparatus main body. For this reason, the scanning device can be effectively installed even in a small space in the hospital, and maintenance of the sub-scanning conveyance means and the scanning light irradiation means can be easily performed simply by pulling out the unit in the lateral direction. Become.
