Description
【0001】[0001]
本考案は移動形X線装置に係り、特にX線管焦点と被検体表面間の距離を制限 する距離保持具に関する。 The present invention relates to a mobile X-ray apparatus, and more particularly to a distance holder that limits the distance between the X-ray tube focus and the surface of a subject.
【0002】[0002]
移動形X線装置は、X線を照射するための高電圧を発生させるX線高電圧装置 と、撮影条件等によりX線の照射を制御するX線制御装置と、所定範囲内を移動 し被検体にX線を照射するX線管装置とを移動台車に搭載させ病室を移動する。 そして、移動形X線装置ではX線管焦点と人体皮膚間距離(以下、SSDと称す る)が30cm未満とならないような処置を講ずるようJIS Z 4701に 規定されている。このため従来の装置では、X線管装置のX線照射方向に取り付 けられるX線絞り装置のケースを長くしたり、あるいはX線絞り装置にU字形の 距離保持具を取り付けてSSDが30cm未満にならないようにしていた。 The mobile X-ray device includes an X-ray high-voltage device that generates a high voltage for irradiating X-rays, an X-ray control device that controls the irradiation of X-rays according to imaging conditions, and the like, and moves within a predetermined range. An X-ray tube device for irradiating the specimen with X-rays is mounted on a moving carriage to move the patient room. In the moving X-ray apparatus, JIS Z 4701 stipulates that the distance between the focal point of the X-ray tube and the human skin (hereinafter referred to as SSD) should not be less than 30 cm. Therefore, in the conventional device, the case of the X-ray diaphragm device mounted in the X-ray irradiation direction of the X-ray tube device is lengthened, or the U-shaped distance holder is attached to the X-ray diaphragm device to increase the SSD to 30 cm. I was trying not to be less than.
【0003】[0003]
従来の移動形X線装置は、病室を移動してX線撮影を行うので、移動時にはX 線管装置を操作者の手前側へ回転させて下方に降ろし走行安定性を確保している が、X線絞り装置のケースを長くしたものや距離保持具を備えたものでは、X線 管装置の高さがSSD分の約30cm程度高くなるため、図3のように前方視界 が狭くなり移動時に支障を来していた。 本考案の目的は、移動させる際の前方視界を確保し安全な移動をさせることに ある。 Since the conventional mobile X-ray device moves the patient room to perform X-ray imaging, the X-ray tube device is rotated to the operator's front side and lowered down to ensure traveling stability when moving. In the case where the X-ray diaphragm device has a long case or is equipped with a distance holder, the height of the X-ray tube device is increased by about 30 cm corresponding to the SSD, so that the forward view becomes narrow as shown in FIG. I was having trouble. An object of the present invention is to secure a forward field of view when moving the vehicle so that the vehicle can be moved safely.

上記目的を達成するために、X線管装置を所定の範囲内で移動可能に支持する 支柱とX線を照射させるためのX線高電圧装置とX線の照射を制御するX線制御 装置を移動台車に搭載すると共に、前記X線管装置へ被検体表面とX線管焦点と の距離を撮影時にある一定距離以上確保する距離保持具を設けた移動形X線装置 において、上記距離保持具を上記距離方向へ伸縮自在に設けると共に、前記距離 保持具の位置が上記一定距離の位置にあるか否かを検出する検出器を備えたもの である。 In order to achieve the above-mentioned object, a support for movably supporting an X-ray tube device, an X-ray high-voltage device for irradiating X-rays, and an X-ray control device for controlling X-ray irradiation are provided. A mobile X-ray device, which is mounted on a movable carriage and which is provided with a distance holder for securing a distance between a surface of a subject and an X-ray tube focal point to the X-ray tube apparatus at a certain distance or more at the time of image capturing. And a detector for detecting whether or not the position of the distance holder is at the fixed distance.
【0005】[0005]
距離保持具は、移動時にはX線管装置をX線制御装置に押し付けると距離保持 具が収縮しX線絞り装置に収納される。撮影時には距離保持具はSSDを確保す る分の高さがあり距離保持具が被検体に触れさらに押すと距離保持具が収縮し、 この収縮を検出器が検出するとX線は照射されない。これにより、移動時の視界 を確保でき、また撮影時にSSD以下では照射しないようにできる。 When the X-ray tube device is pressed against the X-ray control device during movement, the distance holding device contracts, and the distance holding device is stored in the X-ray diaphragm device. At the time of imaging, the distance holder has a height enough to secure the SSD, and when the distance holder touches the subject and pushes further, the distance holder contracts, and when the contraction is detected by the detector, X-rays are not emitted. As a result, it is possible to secure a field of view when moving and to prevent irradiation below the SSD when shooting.

本考案の一実施例を図1及び図2により説明する。図1は本考案の一実施例を 示す一部透視斜視図、図2は本実施例を用いた移動形X線装置の概略側面図であ る。1はX線絞り装置、2は距離保持具でU字形形状をしている。3は距離保持 具2の端部を2ヵ所の軸穴で案内支持するコの字形状の軸受、4は距離保持具2 が外れないよう距離保持具2の端部に固定するE形止め輪、5は距離保持具2を 伸縮させるスプリング、6は距離保持具2が収縮したか否かを検出する検出スイ ッチ、7はX線管装置、8はX線制御装置、9はX線管装置7を移動させる支柱 である。 An embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a partially transparent perspective view showing an embodiment of the present invention, and FIG. 2 is a schematic side view of a mobile X-ray apparatus using this embodiment. Reference numeral 1 is an X-ray diaphragm device, and 2 is a distance holder, which is U-shaped. Reference numeral 3 denotes a U-shaped bearing that guides and supports the end portion of the distance holding tool 2 through two shaft holes, and 4 denotes an E-shaped retaining ring that is fixed to the end portion of the distance holding tool 2 so that the distance holding tool 2 does not come off. 5 is a spring for expanding and contracting the distance holder 2, 6 is a detection switch for detecting whether or not the distance holder 2 is contracted, 7 is an X-ray tube device, 8 is an X-ray control device, and 9 is an X-ray. It is a support for moving the pipe device 7.
【0007】 まず、構成を説明すると、X線絞り装置1の内部側面に軸受3が取り付けられ 、この軸受3にU字形の距離保持具2が摺動可能に保持される。そして、E形止 め輪4は距離保持具2の端部を固定し、軸受3の上部軸穴部に支持され距離保持 具2が抜けないようにする。軸受3の上部と下部の軸穴の間には距離保持具2を 通したスプリング5を設け、このスプリング5は距離保持具2を常に下方に押し 下げている。スプリング5が距離保持具2を押し下げるために、軸受3の上下の 軸穴間を通った距離保持具2の下部の軸穴側に止め具を設け、上部軸穴部と止め 具の間にスプリング5を置く。そして、距離保持具2が収縮した場合に検出スイ ッチ6が押されるよう距離保持具2の端部付近に配置されている。この距離保持 具2はX線絞り装置1の内部側面に対向して2個設けられている。First, the structure will be described. A bearing 3 is attached to an inner side surface of the X-ray diaphragm device 1, and a U-shaped distance holder 2 is slidably held by the bearing 3. Then, the E-shaped retaining ring 4 fixes the end portion of the distance retainer 2 and is supported by the upper shaft hole of the bearing 3 so that the distance retainer 2 does not come off. A spring 5 passing through the distance holder 2 is provided between the upper and lower shaft holes of the bearing 3, and the spring 5 constantly pushes the distance holder 2 downward. In order for the spring 5 to push down the distance holder 2, a stopper is provided on the lower shaft hole side of the distance holder 2 which passes between the upper and lower shaft holes of the bearing 3, and the spring is provided between the upper shaft hole and the stopper. Put 5 The distance holder 2 is arranged near the end of the distance holder 2 so that the detection switch 6 is pushed when the distance holder 2 contracts. Two distance holders 2 are provided so as to face the inner side surface of the X-ray diaphragm device 1.
【0008】 次に移動時、撮影時における本実施例の動作を説明する。移動時にはX線管装 置7を支柱9を中心にして操作者側、つまりX線制御装置8側に回転させ、X線 管装置7を押し下げる。すると、距離保持具2はX線制御装置8に当たるが、さ らにX線管装置7を押し下げると、距離保持具2は軸受3に案内されスプリング 5を押してX線絞り装置1の中に収縮されていく。これにより、移動収納時のX 線管装置7の位置が従来より距離保持具2の高さ分だけ低くすることができる。Next, the operation of this embodiment during movement and shooting will be described. At the time of movement, the X-ray tube device 7 is rotated around the column 9 toward the operator side, that is, the X-ray control device 8 side, and the X-ray tube device 7 is pushed down. Then, the distance holder 2 hits the X-ray controller 8, but when the X-ray tube device 7 is further pushed down, the distance holder 2 is guided by the bearing 3 and pushes the spring 5 to contract into the X-ray diaphragm device 1. Will be done. As a result, the position of the X-ray tube device 7 when moved and stored can be lowered by the height of the distance holder 2 as compared with the conventional case.
【0009】 また、撮影時はX線管装置7を被検体側へ回転させて撮影位置まで持っていく 。この時、X線管装置7を下げて距離保持具2が被検体に触れさらに押し下げる と、前記移動時の時と同様に距離保持具2がX線絞り装置1内に収縮されていく 。そして、距離保持具2の高さがSSDより低くなると、距離保持具2の端部が 検出スイッチ6を押し、この検出スイッチ6からX線制御装置8に信号を送りX 線が照射しないように制御する。Further, at the time of photographing, the X-ray tube device 7 is rotated toward the subject side and brought to the photographing position. At this time, when the X-ray tube device 7 is lowered and the distance holder 2 touches the subject and further pushes it down, the distance holder 2 is contracted into the X-ray diaphragm device 1 as in the case of the movement. Then, when the height of the distance holder 2 becomes lower than the SSD, the end of the distance holder 2 pushes the detection switch 6, and the detection switch 6 sends a signal to the X-ray controller 8 so that the X-rays are not irradiated. Control.
【0010】 以上のように本実施例では、距離保持具2を伸縮可能とすることにより、移動 時に従来より距離保持具2の分だけ低く収納でき前方視界が良好となる。また、 距離保持具2の収縮を検出スイッチ6により検出することにより、撮影時に距離 保持具2の高さがSSD以下となった場合にX線が照射できなくなるので安全な 撮影ができる。As described above, in the present embodiment, by making the distance holding tool 2 extendable, the distance holding tool 2 can be stored lower than the conventional one when moving, and the forward visibility is improved. Further, by detecting the contraction of the distance holder 2 by the detection switch 6, when the height of the distance holder 2 becomes less than or equal to SSD at the time of photographing, X-rays cannot be emitted, so that safe photographing can be performed.
【0011】[0011]
本考案によれば、距離保持具を伸縮可能としたため、移動時の前方視界が妨げ られることがないので十分な視界を確保できる。また、距離保持具の収縮の検出 をする検出器を設けたので、撮影時に距離保持具が収縮したことを検出してX線 を照射させない、つまりSSD以下では撮影できないので安全な撮影ができる。 According to the present invention, since the distance holder can be expanded and contracted, the forward field of view when moving is not obstructed, so that a sufficient field of view can be secured. Further, since the detector for detecting the contraction of the distance holding tool is provided, it is possible to detect the contraction of the distance holding tool at the time of photographing and not to irradiate X-rays, that is, since it is not possible to shoot below SSD, it is possible to carry out safe photographing.
