Description

体動抑制装置及び体動抑制方法並びに体動抑制バッグBody motion suppression device, body motion suppression method, and body motion suppression bag
　本発明は、放射線を用いた検査及び／又は治療が施される患者の所定部位に対応する体表面に所定の荷重を加えて所定部位の体動を抑制する体動抑制装置及びこの体動抑制装置を用いた体動抑制方法並びにこれらに用いられる体動抑制バッグに関する。 The present invention relates to a body movement suppressing device that suppresses body movement of a predetermined part by applying a predetermined load to a body surface corresponding to a predetermined part of a patient to be examined and / or treated using radiation. The present invention relates to a body motion suppressing method using a device and a body motion suppressing bag used in these methods.
　癌等の悪性腫瘍の治療として、患部にＸ線又は陽子線・重粒子線のような粒子線等の放射線を照射する放射線治療が行われることがある。この放射線治療では、患部に正確に放射線を照射することが必要である。しかし、患者が放射線の照射中に動くと患部も移動し、放射線を患部に正確に照射できないおそれがある。胸腹部内又は骨盤内に患部が存在する場合、患者の呼吸に伴う胸腹部の動きによっても、患部の位置が移動することがある。従って、患部が存在する患者の所定部位の体動を確実に抑制しつつ、放射線を照射することが必要である。また、放射線治療前に、患部の位置を正確に把握すべく、Ｘ線を使ったコンピュータ断層写真（Computed Tomography:CT）等による検査もなされる。その際にも、患者の所定部位の体動を十分に抑制することが必要である。 As a treatment for malignant tumors such as cancer, radiation therapy may be performed in which the affected area is irradiated with radiation such as X-rays or particle beams such as proton beams or heavy particle beams. In this radiotherapy, it is necessary to accurately irradiate the affected area with radiation. However, if the patient moves during the irradiation of radiation, the affected area also moves, and there is a possibility that the affected area cannot be accurately irradiated with radiation. When the affected area exists in the thoracoabdominal region or the pelvis, the position of the affected area may also be moved by the movement of the thoracoabdominal region accompanying the patient's breathing. Therefore, it is necessary to irradiate the radiation while reliably suppressing the body movement of the predetermined part of the patient where the affected part exists. In addition, an examination by a computed tomography (CT) using X-rays or the like is performed in order to accurately grasp the position of the affected area before radiation treatment. In that case as well, it is necessary to sufficiently suppress the body movement of the predetermined part of the patient.
　従来、患者の体動を抑制する抑制装置としては、例えば下記特許文献１に記載されているように、患者の所定部位に巻き付けたベルトと体表面との間に袋状の空気室を設け、この空気室に空気を注入して患者の所定部位の体表面を押圧し体動を抑制するものである。しかし、この抑制具は、患者にどの程度の荷重が加えられているのか不明であり、放射線治療のように数日に亘って繰り返し行われる場合、患者に加えられる荷重にバラツキが生じるおそれがあり、患者の体動を十分に抑制できているかも不明である。 Conventionally, as a suppression device for suppressing body movement of a patient, for example, as described in Patent Document 1 below, a bag-like air chamber is provided between a belt wound around a predetermined part of a patient and the body surface, Air is injected into the air chamber to press the body surface of a predetermined part of the patient and suppress body movement. However, it is unclear how much load is applied to the patient with this suppressor, and there is a risk that the load applied to the patient may vary when repeated over several days, such as radiotherapy. It is also unclear whether the patient's body movement can be sufficiently suppressed.
　この点、下記特許文献２には、患者の体動が十分に抑制できていることを確認可能な体動抑制装置が記載されている。この体動抑制装置は、寝台上に仰臥する患者の体幹部を固定する体幹部固定具と、患者の腹部の上方に架設されている支持台と、この支持台に上下方向に駆動可能に支持されている駆動軸と、この駆動軸の先端に設けられている圧迫板とから構成され、駆動軸を下方に駆動すると圧迫板が患者の季肋下部を押して横隔膜を圧迫する横隔膜圧迫具を備え、可撓性を有し全体が扁平なシート状を呈する中空体内に空気が気密的に封入されている受圧容器が、患者と圧迫板の間に挟まれるように設けられ、且つ受圧容器と所定の管路を介して連通している中空の格納容器内に、受圧容器に作用する圧力を封入された空気を介して検出する検出センサーが設けられている。この検出センサーは、高感度の圧電素子が用いられている。 In this regard, Patent Document 2 described below describes a body movement suppressing device that can confirm that the body movement of a patient can be sufficiently suppressed. This body movement suppression device is supported by a trunk fixing tool that fixes a patient's trunk lying on a bed, a support frame that is installed above the patient's abdomen, and a vertically movable drive on the support frame. And a compression plate provided at the tip of the drive shaft, and when the drive shaft is driven downward, the compression plate pushes the lower part of the patient's season and presses the diaphragm. A pressure receiving container in which air is hermetically sealed in a hollow body having a flat sheet shape that is flexible is provided so as to be sandwiched between a patient and a compression plate, and the pressure receiving container and a predetermined tube A detection sensor for detecting the pressure acting on the pressure receiving container through the enclosed air is provided in a hollow storage container communicating with the passage. This detection sensor uses a highly sensitive piezoelectric element.
　特許文献２に記載されている抑制装置によれば、患者の呼吸をモニターでき、患者の呼吸による体動が十分に抑制できていることを確認できる。しかしながら、患者の呼吸のモニターは、受圧容器に封入されている空気圧力の変化によるものであり、受圧容器の空気圧力は、患者と受圧容器の接触面積、患者の体形の変形程度、受圧容器の変形度合によって変化することから、放射線治療のように数日に亘って繰り返し行われる場合、放射線照射の都度、体形変化のある患者に所定の荷重を確実に加えることは困難である。また、受圧容器の圧力変化は、患者の呼吸による圧力変化に心臓の鼓動による圧力変化も加わって、検出センサーからの信号に多くのノイズが入り込むことから、呼吸動作のみの圧力変化による信号を抽出する煩雑な操作も必要とし、抑制装置が複雑化する。 According to the suppression device described in Patent Document 2, it is possible to monitor the patient's respiration and confirm that the body movement due to the patient's respiration is sufficiently suppressed. However, the patient's breathing monitor is based on the change in air pressure enclosed in the pressure receiving container. The air pressure in the pressure receiving container depends on the contact area between the patient and the pressure receiving container, the degree of deformation of the patient's body shape, Since it changes depending on the degree of deformation, it is difficult to reliably apply a predetermined load to a patient whose body shape has changed each time radiation irradiation is performed repeatedly for several days as in radiotherapy. In addition, the pressure change in the pressure-receiving container adds a pressure change due to the heartbeat in addition to the pressure change due to the patient's breathing, and a lot of noise enters the signal from the detection sensor. Complicated operation is also required, and the suppression device becomes complicated.

By providing at least one surface of the bag-like part so that a load applied to the body surface of the patient can be detected, the amount of air to the bag-like part can be adjusted to easily adjust to an appropriate load. Furthermore, when treatment is performed repeatedly over a predetermined period, such as radiotherapy, the amount of air supplied to the bag-like portion is adjusted based on the load detected by the load detection sensor even if the patient's body shape changes. In addition, the patient's body movement can be reliably suppressed by adjusting to an appropriate load.
　前記荷重検出センサーとしての歪センサーが設けられた板状部が前記袋状部よりも硬く、前記板状部及び前記歪センサーが前記袋状部の少なくとも一面に設けられていることにより、簡単な構造で袋状部による患者に加えられる荷重及び患者の呼吸パターンをモニターできる。 The plate-like portion provided with the strain sensor as the load detection sensor is harder than the bag-like portion, and the plate-like portion and the strain sensor are provided on at least one surface of the bag-like portion, thereby simplifying The structure allows monitoring of the load applied to the patient by the bag and the patient's breathing pattern.
　前記板状部が、前記袋状部の前記押圧部材側の面に接合されており、前記押圧部材には、前記袋状部が膨出したとき、前記板状部及び前記歪センサーが挿入される位置決め用凹部が形成されていることにより、膨出した袋状部で患者の所定部位に確実に所定の荷重を加えることができる。 The plate-like portion is joined to the surface of the bag-like portion on the pressing member side, and the plate-like portion and the strain sensor are inserted into the pressing member when the bag-like portion swells. By forming the positioning concave portion, a predetermined load can be reliably applied to a predetermined portion of the patient by the bulging bag-shaped portion.

　前記荷重検出センサーとしての歪センサーを、前記歪センサーよりも大形の板状部に設けることにより、小形の歪センサーの取扱性を向上できる。 The handleability of the small strain sensor can be improved by providing the strain sensor as the load detection sensor in a larger plate-like portion than the strain sensor.

It is preferable that positioning can be easily performed. The fixed bag is filled with granular material in the bag shape, and when the bag shape is in an atmospheric pressure state, the granular material can move freely in the bag shape, and when the bag shape is in a reduced pressure state, It becomes a restraint state within the bag shape. When such a fixed bag is placed at a predetermined position on the base plate 12 and the patient 10 is placed on the fixed bag, the granular material is shaped in the shape of the body surface on the back side of the patient 10 in the bag shape at atmospheric pressure. The upper surface side of the fixed bag becomes a shape that follows the shape of the body surface on the back side of the patient 10. Next, the inside of the bag of the fixed bag is brought into a decompressed state, whereby the granular material in the bag is in a restrained state, and the shape on the upper surface side of the fixed bag is fixed.

It is connected. While the patient 10 is fixed to a predetermined position of the base plate 12 by the attached fixing shell 14, deep breathing using the diaphragm is suppressed, and body movement of the chest due to deep breathing is suppressed.
　このように患者１０の胸部に被着された固定用シェル１４と胸部の鳩尾に相当する体表面との間には、図１に示すように固定用シェル１４による体表面への押圧力を調整する圧力調整手段としての第１の体動抑制バッグＢ（以下、バッグＢという。）の袋状部１６が挿入されている。図１に示すように固定用シェル１４よりも小形の袋状部１６を具備し、その固定用シェル１４側の面に板状部１７が接合されている。このバッグＢの正面図を図２（ａ）に示す。バッグＢの袋状部１６は、六角形であって、その一面側に、袋状部１６よりも硬く固定用シェル１４による押圧力で変形しない板状部１７が接合されている。袋状部１６の一辺の片寄った位置からは、空気供給路１８が引き出されている。袋状部１６は、図２（ａ）のＸ－Ｘでの断面図である図２（ｂ）に示すように、二枚のガスバリア性を有する生地１６ａ，１６ｂから形成されており、生地１６ａ，１６ｂの両端部１６ｃ，１６ｃが４～６ｍｍ幅で溶着されている。また、空気供給路１８も、図２（ａ）のＹ－Ｙでの横断面図である図２（ｃ）に示すように、二枚のガスバリア性を有する生地１８ａ，１８ｂの両端部１８ｃ，１８ｃが幅４～６ｍｍに亘って溶着されて筒状に形成されている。この空気供給路１８には、図２（ｃ）に示すように、空気供給手段に連結されるコネクタ２０が一端に装着されたチューブ２１が挿入されており、チューブ２１の他端は袋状部１６の入口近傍に位置している。このようにチューブ２１が空気供給路１８に挿入されることにより、図１に示すように空気供給路１８の一部が固定用シェル１４と患者１０との間に挟まれても、袋状部１６への吸気供給道を確実に確保できる。尚、チューブ２１は、Ｘ線等の放射線を透過する非磁性体の材料、例えばポリ塩化ビニル等のプラスチック製のものであることが好ましい。 As shown in FIG. 1, the pressing force applied to the body surface by the fixing shell 14 is adjusted between the fixing shell 14 applied to the chest of the patient 10 and the body surface corresponding to the pigeon tail of the chest.

The plate-like portion 17 of the bag B thus inserted is inserted into a positioning recess 14a formed in advance in the fixing shell 14 as shown in FIG. The fixing shell 14 having such a positioning recess 14a can be processed by heating a plate or mesh body made of a thermoplastic resin having a low melting point such as poly-ε-caprolactone having a melting point of 60 ° C. After adjusting the temperature to such a degree that it can be bent to a certain extent and does not cause burns, the bag-like portion 16 of the bag B shown in FIG. 2 is directly pressed against the chest 10a of the patient 10 placed at a predetermined position. It is possible to obtain one having a shape following the body surface shape of the chest 10a and having a positioning recess 14a opened at a predetermined position on the inner surface side. The positioning concave portion 14a of the fixing shell 14 can position the bag B at a predetermined position when the fixing shell 14 and the bag B are attached to a predetermined portion of the patient 10 at the time of another radiotherapy or examination. .
　図４に示すように胸部１０ａの体表面と固定用シェル１４との間に挿入された図２に示すバッグＢの袋状部１６には、図１に示すように固定用シェル１４の外方に延出されている空気供給路１８のコネクタ２０に、途中に圧力計２６が取り付けられたチューブ２８を介して連結された空気供給手段としての空気ポンプ２４から空気が供給される。空気が供給された袋状部１６は膨出して胸部１０ａの所定箇所に所定の荷重を加えると共に、同一荷重で板状部１７も固定用シェル１４に押し付ける。この袋状部１６が板状部１７を固定用シェル１４に押し付ける力は、歪センサー１９を圧縮し荷重として検出できる。 As shown in FIG. 4, the bag-like portion 16 of the bag B shown in FIG. 2 inserted between the body surface of the chest 10a and the fixing shell 14 has an outer side of the fixing shell 14 as shown in FIG. Air is supplied from an air pump 24 serving as an air supply means connected to a connector 20 of the air supply path 18 that is extended through a tube 28 to which a pressure gauge 26 is attached midway. The bag-like portion 16 supplied with air bulges and applies a predetermined load to a predetermined portion of the chest 10a, and the plate-like portion 17 is also pressed against the fixing shell 14 with the same load. The force with which the bag-like portion 16 presses the plate-like portion 17 against the fixing shell 14 can be detected as a load by compressing the strain sensor 19.
　このように歪センサー１９で検出された荷重が適正値となるように、圧力計２６で計測される袋状部１６の圧力を参考にしつつ空気ポンプ２４からの空気量を調整する。図１に示すようにバッグＢを胸部１０ａの鳩尾に装着し、袋状部１６に空気ポンプ２４から空気を供給して袋状部１６を膨出して呼吸による体動を抑制する場合、歪センサー１９で鳩尾に加える荷重を検出できると共に、荷重の経時変化をモニターすることにより、患者１０の呼吸パターンをモニターできる。このモニターによれば、患者１０の横隔膜による深呼吸を抑制できたか否か判別できる。その一例を図５に示す。図５において、患者１０の横隔膜による深呼吸を抑制したとき、肺が拡張したときの最高荷重は６００ｇｆであり、肺が萎んだときの最低荷重は４００ｇｆであった。図５に示すモニターは、歪センサー１９からの電気信号を単に増幅しただけのものである。 Thus, the air amount from the air pump 24 is adjusted with reference to the pressure of the bag-like portion 16 measured by the pressure gauge 26 so that the load detected by the strain sensor 19 becomes an appropriate value. As shown in FIG. 1, when the bag B is attached to the pigeon tail of the chest 10a and air is supplied to the bag-like portion 16 from the air pump 24 to bulge the bag-like portion 16 to suppress body movement due to breathing, a strain sensor The load applied to the pigeon tail can be detected at 19 and the respiratory pattern of the patient 10 can be monitored by monitoring the change with time of the load. According to this monitor, it is possible to determine whether or not deep breathing by the diaphragm of the patient 10 has been suppressed. An example is shown in FIG. In FIG. 5, when deep breathing by the diaphragm of the patient 10 was suppressed, the maximum load when the lungs were expanded was 600 gf, and the minimum load when the lungs were deflated was 400 gf. The monitor shown in FIG. 5 is simply an amplified electric signal from the strain sensor 19.
　患者１０の体形が固定用シェル１４を成形したときよりも変形し、図６（ａ）に示すように、患者１０の胸部１０ａの鳩尾に対応する体表面及びバッグＢと固定用シェル１４との間に隙間２２が形成されたとき、固定用シェル１４のみでは胸部１０ａの鳩尾に十分な荷重を加えることができず、胸部１０ａの体動を十分に抑制できない。このような場合、図６（ｂ）に示すように袋状部１６内に空気供給路１８を介して空気ポンプ２４（図１）から空気を供給し、袋状部１６を膨出することにより、隙間２２を閉塞して胸部１０ａの鳩尾に対応する体表面に所定の荷重を加えることができ、横隔膜の呼吸による体動を抑制できる。このとき、図４に示すように、膨出した袋状部１６により板状部１７が固定用シェル１４の位置決め用凹部１４ａ内に挿入され、膨出した袋状部１６により正確に胸部１０ａの鳩尾に対応する体表面に所定の荷重を加えることができる。 The body shape of the patient 10 is deformed more than when the fixing shell 14 is molded, and the body surface corresponding to the pigeon tail of the chest 10a of the patient 10 and the bag B and the fixing shell 14 are deformed as shown in FIG. When the gap 22 is formed between them, the fixing shell 14 alone cannot apply a sufficient load to the dovetail of the chest 10a, and the body movement of the chest 10a cannot be sufficiently suppressed. In such a case, as shown in FIG. 6 (b), air is supplied from the air pump 24 (FIG. 1) through the air supply path 18 into the bag-like portion 16, and the bag-like portion 16 is expanded. A predetermined load can be applied to the body surface corresponding to the pigtail of the chest 10a by closing the gap 22, and body movement due to breathing of the diaphragm can be suppressed. At this time, as shown in FIG. 4, the plate-like portion 17 is inserted into the positioning concave portion 14 a of the fixing shell 14 by the bulging bag-like portion 16, and the bulging bag-like portion 16 accurately A predetermined load can be applied to the body surface corresponding to the pigeon tail.
　図６に示すバッグＢは、患者１０の胸部１０ａの鳩尾に対応する体表面と固定用シェル１４との間隙２２に、板状部１７が固定用シェル１４側となるように挿入されているが、患者１０の体形変形が少ないとき、図７（ａ）に示すように板状部１７を患者１０の体表面側となるように間隙２２に挿入してもよい。この場合、固定用シェル１４に位置決め用凹部１４ａを形成することは要しない。図７（ａ）に示すように板状部１７が患者１０の体表面側となるように挿入された袋状部１６は、空気供給路１８を介して空気ポンプ２４（図１）から空気が供給され膨出すると、図７（ｂ）に示すように板状部１７を患者１０の対応する体表面に押し付けて、その体表面の形状を矯正しつつ、間隙２２を閉塞して患者１０の胸部１０ａの鳩尾に対応する体表面に所定の荷重を加えることができる。以上、説明してきた歪センサー１９は、上下方向の圧縮を検出するものであったが、左右方向への伸縮を検出する歪センサーであってもよい。このような歪センサーは袋状部１６の一面側に直接形成されていてもよい。 The bag B shown in FIG. 6 is inserted into the gap 22 between the body surface corresponding to the pigeon tail of the chest 10a of the patient 10 and the fixing shell 14 so that the plate-like portion 17 is on the fixing shell 14 side. When the patient 10 is less deformed, the plate-like portion 17 may be inserted into the gap 22 so as to be on the body surface side of the patient 10 as shown in FIG. In this case, it is not necessary to form the positioning recess 14 a in the fixing shell 14. As shown in FIG. 7A, the bag-like portion 16 inserted so that the plate-like portion 17 is on the body surface side of the patient 10 receives air from the air pump 24 (FIG. 1) via the air supply path 18. When supplied and swelled, as shown in FIG. 7B, the plate-like portion 17 is pressed against the corresponding body surface of the patient 10 to correct the shape of the body surface and close the gap 22 to close the patient 10. A predetermined load can be applied to the body surface corresponding to the pigtail of the chest 10a. The strain sensor 19 described above detects the compression in the vertical direction, but may be a strain sensor that detects expansion and contraction in the left-right direction. Such a strain sensor may be directly formed on one surface side of the bag-like portion 16.
　これまで説明してきた押圧部材としての固定用シェル１４は、患者１０の胸部１０ａの全体を覆っているが、横隔膜による呼吸に基づく体動の抑制は、患者１０の鳩尾部分のみを押圧することでも可能であることから、図８（ａ）に示す第２の体動抑制装置のように患者１０の鳩尾部分のみを押圧する押圧板３０を押圧部材として用いることができる。図８（ａ）に示す第２の体動抑制装置は、ベースプレート１２の側端に立設された二本の支柱３２ａ，３２ｂで両端部が支承されている湾曲状の横桟３４に第１の圧力調整手段としての螺子杵３６が螺着されており、螺子杵３６の先端に押圧板３０が取り付けられている。螺子杵３６の後端に取り付けられたツマミ３８を左右方向に回動して、螺子杵３６を回動すると、押圧板３０は上下動し、ベースプレート１２上に載せられた患者１０の鳩尾部分の押圧力を調整できる。この押圧板３０と患者１０の鳩尾部分に対応する体表面との間に、第２の圧力調整手段としてのバッグＢが挿入される。バッグＢは、板状部１７が押圧板３０側となるように挿入されることが好ましい。この場合、押圧板３０には、その部分拡大断面図に示すように板状部１７が挿入される凹部３０ａが形成されていることが、押圧板３０の全面でバッグＢを押圧でき好ましい。また、バッグＢを、その板状部１７を患者１０の体表面側となるように押圧板３０と患者との間に配置してもよい。この場合、押圧板３０に、板状部１７が挿入される凹部３０ａを形成することは要しない。 The fixing shell 14 as the pressing member that has been described so far covers the entire chest 10a of the patient 10, but suppression of body movement based on breathing by the diaphragm can also be performed by pressing only the pigeon tail portion of the patient 10. Since it is possible, the press plate 30 which presses only the pigeon tail part of the patient 10 like the 2nd body movement suppression apparatus shown to Fig.8 (a) can be used as a press member. The second body motion suppressing device shown in FIG. 8A is a first example of a curved horizontal beam 34 supported at both ends by two columns 32a and 32b erected on the side end of the base plate 12. A screw rod 36 as a pressure adjusting means is screwed, and a pressing plate 30 is attached to the tip of the screw rod 36. When the knob 38 attached to the rear end of the screw rod 36 is rotated in the left-right direction, and the screw rod 36 is rotated, the pressing plate 30 moves up and down, and the dovetail portion of the patient 10 placed on the base plate 12 is moved. The pressing force can be adjusted. A bag B as a second pressure adjusting means is inserted between the pressing plate 30 and the body surface corresponding to the pigeon tail portion of the patient 10. The bag B is preferably inserted so that the plate-like portion 17 is on the pressing plate 30 side. In this case, it is preferable that the pressing plate 30 is formed with a recess 30a into which the plate-like portion 17 is inserted as shown in the partial enlarged cross-sectional view so that the bag B can be pressed on the entire surface of the pressing plate 30. Moreover, you may arrange | position the bag B between the press board 30 and a patient so that the plate-shaped part 17 may become the patient's 10 body surface side. In this case, it is not necessary to form the recessed part 30a in which the plate-shaped part 17 is inserted in the press plate 30.
　また、患者１０の鳩尾部分を押圧板３０のみの押圧で横隔膜による呼吸に基づく体動を抑制可能である場合は、図８（ｂ）に示す第３の体動抑制装置のように第１の圧力調整手段としての螺子杵３６の先端に取り付けられた押圧板３０で直接鳩尾部分を押圧することができる。この場合も、板状部１７を患者１０の体表面と押圧板３０との間に配置することにより、板状部１７の歪センサー１９により鳩尾部分の体表面に加えられる荷重を検知しつつ、ツマミ３８を左右方向に回動させて鳩尾部分の体表面に最適荷重を加えることができる。尚、図８（ａ）（ｂ）に示す押圧板３０，支柱３２ａ，３２ｂ，横桟３４，螺子杵３６，ツマミ３８は、放射線を透過する非磁性の材料、例えば樹脂から形成されている。 Further, when body movement based on breathing by the diaphragm can be suppressed by pressing the dovetail portion of the patient 10 only by the pressing plate 30, the first body movement suppressing device shown in FIG. 8B is used. The dovetail portion can be directly pressed by the pressing plate 30 attached to the tip of the screw rod 36 as the pressure adjusting means. Also in this case, by arranging the plate-like portion 17 between the body surface of the patient 10 and the pressing plate 30, while detecting the load applied to the body surface of the pigtail portion by the strain sensor 19 of the plate-like portion 17, An optimum load can be applied to the body surface of the pigeon tail by rotating the knob 38 in the left-right direction. 8A and 8B are made of a nonmagnetic material that transmits radiation, such as a resin, for example, the pressing plate 30, the support columns 32a and 32b, the horizontal rail 34, the screw rod 36, and the knob 38.
　押圧部材としてベルトを用いた第４の体動抑制装置を図９に示す。図９（ａ）に示す第４の体動抑制装置では、患者１０の所定部位に巻き付けたベルト４４を押圧部材として用いたものであって、患者１０の所定部位の体表面とベルト４４との間に、歪センサー１９が配設された板状部１７が袋状部１６の一面側に接合されているバッグＢが挿入されている。ベルト４４の両端部の各々に面ファスナー４６が圧力調整手段として設けられており、ベルト４４の患者２０の所定部位に巻き付けるベルト長を調節することにより、患者１０の所定部位の体表面への押圧力を調整できる。更に、袋状部１６への空気の吸排によってもベルト４４による体表面への押圧力を調整できる。尚、袋状部１６への空気の吸排によるベルト４４の体表面への押圧力の調整が不要な場合は、図９（ｂ）に示す第５の体動抑制装置のように、患者１０の所定部位の体表面とベルト４４との間に歪センサー１９を具備する板状部１７のみを挿入してもよい。 FIG. 9 shows a fourth body movement suppression device using a belt as the pressing member. In the fourth body movement suppressing device shown in FIG. 9A, the belt 44 wound around a predetermined part of the patient 10 is used as a pressing member, and the body surface of the predetermined part of the patient 10 and the belt 44 are used. In the middle, a bag B is inserted in which a plate-like portion 17 provided with a strain sensor 19 is joined to one surface side of the bag-like portion 16. A hook-and-loop fastener 46 is provided at each of both ends of the belt 44 as pressure adjusting means. By adjusting the belt length of the belt 44 wound around the predetermined portion of the patient 20, the pressing of the predetermined portion of the patient 10 onto the body surface is performed. The pressure can be adjusted. Further, the pressing force applied to the body surface by the belt 44 can also be adjusted by sucking and discharging air into the bag-like portion 16. In addition, when adjustment of the pressing force to the body surface of the belt 44 by the air suction / exhaustion to the bag-like portion 16 is unnecessary, the patient's 10 is moved like a fifth body movement suppressing device shown in FIG. Only the plate-like portion 17 having the strain sensor 19 may be inserted between the body surface of the predetermined portion and the belt 44.
　これまで述べてきた板状部１７は、その中央部に歪センサー１９が配設されている。このように板状部１７の中央部に歪センサー１９を正確に配設するためには、図１０（ａ）に示すように板体１７ｂの対向面の中央部に予めセンサー用凹部１９ａを形成しておくことが好ましい。この凹部１９ａは、板体１７ａの対向面に当接する歪センサー１９の先端面が板体１７ｂの面から突出する程度の深さとする。図９に示す板状部１７でも、凹部１９ａから突出した歪センサー１９を取り囲むようにスポンジ等のクッション材２３が接着剤等で接合されている。また、図１０（ｂ）に示す板状部１７のように、歪センサー１９が樹脂１７ｃでインサート成形されてもよい。尚、板状部１７は、放射線を透過する非磁性体の材料で形成されていたが、放射線が図１に示す患者１０の脇側から照射される場合等のように、歪センサー１９が配設されている板状部１７に放射線が実質的に照射されないときは、板状部１７を放射線が非透過性の材料、例えば金属材やセラミック材で形成してもよい。 The strain sensor 19 is disposed at the center of the plate-like portion 17 described so far. Thus, in order to accurately dispose the strain sensor 19 at the center of the plate-like portion 17, as shown in FIG. 10A, a sensor recess 19a is formed in advance at the center of the opposing surface of the plate body 17b. It is preferable to keep it. The recess 19a has a depth such that the front end surface of the strain sensor 19 in contact with the opposing surface of the plate body 17a protrudes from the surface of the plate body 17b. Also in the plate-like portion 17 shown in FIG. 9, a cushion material 23 such as a sponge is joined with an adhesive or the like so as to surround the strain sensor 19 protruding from the concave portion 19a. Moreover, the strain sensor 19 may be insert-molded with the resin 17c like the plate-shaped part 17 shown in FIG.10 (b). Although the plate-like portion 17 is formed of a non-magnetic material that transmits radiation, the strain sensor 19 is arranged as in the case where the radiation is irradiated from the side of the patient 10 shown in FIG. When the plate-like portion 17 provided is not substantially irradiated with radiation, the plate-like portion 17 may be formed of a material that does not transmit radiation, such as a metal material or a ceramic material.
　図１、図２、図４、図６～図９に示すバッグＢは、袋状部１６の患者１０の体表面に直接接触する面側に何等設けられておらず、患者１０の体表面温度や心拍を監視する必要ある場合、バッグＢと別体の体温センサーや心拍センサーを患者１０に装着して、放射線を用いた検査及び／又は検査を施している。この点、図１１に示す第２の体動抑制バッグＢ２（以下、バッグＢ２という。）は、固定用シェル１４側となる袋状部１６の生地１６ａに図２に示す板状部１７が設けられ、袋状部１６の患者１０側となる生地１６ｂに患者１０の心拍及び／又は体表面温度を検出するバイタル検出センサー４０が設けられている。このバッグＢ２を用いて患者１０の体動を抑制して放射線を使った検査及び／又は検査を施す際に、別体の体温センサーや心拍センサーを患者１０に装着することなく、患者１０の心拍及び／又は体表面温度のバイタルデータを監視できる。尚、バッグＢ２の生地１６ａ側の板状部１７等の説明は図２の説明と重複するため省略する。 The bag B shown in FIGS. 1, 2, 4, and 6 to 9 is not provided on the surface side of the bag-like portion 16 that directly contacts the body surface of the patient 10, and the body surface temperature of the patient 10 is not provided. When it is necessary to monitor the heart rate, a body temperature sensor or a heart rate sensor separate from the bag B is attached to the patient 10, and an examination and / or examination using radiation is performed. In this regard, the second body movement suppression bag B 2 (hereinafter referred to as the bag B 2 ) shown in FIG. 11 has a plate-like portion 17 shown in FIG. 2 on the fabric 16 a of the bag-like portion 16 on the fixing shell 14 side. And a vital detection sensor 40 for detecting the heartbeat and / or body surface temperature of the patient 10 is provided on the fabric 16b of the bag-like portion 16 on the patient 10 side. Using this bag B 2 when performing the inspection and / or inspection with radiation to suppress body movement of the patient 10, without attaching to the patient 10 body temperature sensor or heart rate sensor separate, the patient 10 Heart rate and / or body surface temperature vital data can be monitored. The description of such a plate-like portion 17 of the fabric 16a side of the bag B 2 are omitted for overlapping with the description of FIG.
　図１１に示すバイタル検出センサー４０は、一対のコ字状のフレキシブル電極４０ａ，４０ａが生地１６ｂの表面に形成され、その末端が送信器４０ｂに連結されている。フレキシブル電極４０ａは、生地１６ｂに導電性ペーストで形成された導電層４１ａが接着層４１ｂで接合されている。導電層４１ａは、患者１０の体表面に直接接触して体表面温度又は心拍を検出し、その検出データを送信器４０ｂからコントロール室の受信器に送信される。 In the vital detection sensor 40 shown in FIG. 11, a pair of U-shaped flexible electrodes 40a and 40a are formed on the surface of the fabric 16b, and the ends thereof are connected to the transmitter 40b. In the flexible electrode 40a, a conductive layer 41a formed of a conductive paste is bonded to the cloth 16b with an adhesive layer 41b. The conductive layer 41a directly contacts the body surface of the patient 10 to detect the body surface temperature or heartbeat, and the detection data is transmitted from the transmitter 40b to the receiver in the control room.
　以上、説明してきたバッグＢの袋状部１６は、六角形であったが、四角形であってもよい。また、空気供給路１８も、袋状部１６の辺の中央部から引き出されてもよく、板状部１７の側面にコネクタ２５ｂが形成されていてもよい。更に、歪センサー１９が配設されている板状部１７をバッグＢの袋状部１６と同等以上の大きさに形成してもよく、患者１０の所定部位の体表面に加えられる荷重を更に精度よく把握すべく、板状部１７を袋状部１６の両面に設けてもよい。 As described above, the bag-like portion 16 of the bag B described above has a hexagonal shape, but may have a rectangular shape. The air supply path 18 may also be drawn out from the center of the side of the bag-like portion 16, and the connector 25 b may be formed on the side surface of the plate-like portion 17. Further, the plate-like portion 17 on which the strain sensor 19 is disposed may be formed to have a size equal to or larger than that of the bag-like portion 16 of the bag B, and a load applied to the body surface of a predetermined part of the patient 10 is further increased. In order to grasp accurately, the plate-like part 17 may be provided on both surfaces of the bag-like part 16.
