Description
本発明はX線透視撮影用の被検者圧迫装置に係り、殊更各種のX線透視撮影台へ自由自在に後付け汎用できるように工夫したものである。 The present invention relates to a subject compression apparatus for X-ray fluoroscopy, and is particularly devised so that it can be freely retrofitted to various X-ray fluoroscopy tables.
消化器官を診断するために使われるX線透視撮影用の被検者圧迫装置としては、既に特開平7−327980号が提案されており、この明細書段落〔0010〕には「空気袋を被検者を載置するテーブル上のX線照射範囲中に取り付けておけば、被検者がテーブル面に腹部を向けて俯臥位にある場合でも、腹部を適度に押圧することが可能となる。」旨が記載されている点で、本発明に最も近似する公知発明であると言える。
ところが、そのテーブル(3)上に俯臥した被検者の腹部を圧迫するための具体的な構成は、上記公知発明に少しも開示されておらず、あくまでも文章だけの仮定的な抽象論であるに過ぎない。 However, the specific configuration for pressing the subject's abdomen lying on the table (3) is not disclosed at all in the above-mentioned known invention, and is a hypothetical abstraction only of text. Only.
その圧迫機構部(1)の具体的な構成としては図1〜3のように、上下移動可能な支持棒(11)の先端部に付属する固定板(12)の下面へ、金具(14)により空気袋(13)を取り付け固定して、テーブル(3)上に仰臥した被検者の腹部を上方から押圧するようになっているため、このままの構成にとどまる限り、テーブル(3)上に俯臥した被検者の腹部を圧迫することはできず、各種のX線透視撮影台へ自由自在に後付け汎用することも不可能である。 As a specific configuration of the compression mechanism (1), as shown in FIGS. 1 to 3, the metal fitting (14) is attached to the lower surface of the fixing plate (12) attached to the tip of the support bar (11) movable up and down. Since the air bag (13) is attached and fixed by the above and the abdomen of the subject who is supine on the table (3) is pressed from above, as long as the configuration remains as it is, it remains on the table (3). It is impossible to press the abdomen of a subject who has become angry, and it is impossible to freely apply it to various X-ray fluoroscopic imaging tables.
更に、上記公知発明の場合空気袋(13)が図3に示唆された複数(合計9個)の空気室(a)〜(i)を有しており、その「各空気室には圧縮空気を送り込んだり、排出したりする空気弁付きのホース(図示せず)が個別に取り付けられており、これらのホースは図示しない空気ポンプに接続されている。また、空気弁の操作は、診断術者が自在に操作できるように構成されている。」(明細書段落〔0016〕)と記載されているが、その具体的な構成までは図解説明されておらず、やはり概念論の域を出ない。 Further, in the case of the above-mentioned known invention, the air bag (13) has a plurality (total nine) of air chambers (a) to (i) suggested in FIG. A hose with an air valve (not shown) for sending and discharging air is individually attached, and these hoses are connected to an air pump (not shown). It is configured so that it can be freely operated by the user ”(paragraph [0016] of the specification), but the specific configuration is not illustrated and explained, and still goes out of the conceptual field. Absent.
つまり、空気袋(13)における各空気室(a)〜(i)の気密化された区画形成状態や、その各空気室(a)〜(i)とこれらに共通する空気ポンプとの個別な接続配管系統、各ホースの空気弁を操作する電気制御系統、各空気室(a)〜(i)の選択とその個別の空気給排制御方法などが、悉く当業者にとって不明であり、そのためか未だ実用化されるまでに至っていない。 That is, each air chamber (a) to (i) in the air bag (13) is formed in an airtight section, and each air chamber (a) to (i) and the air pump common to these air chambers are individually formed. The connection piping system, the electric control system that operates the air valve of each hose, the selection of each air chamber (a) to (i) and the individual air supply / discharge control method are unclear to those skilled in the art. It has not yet been put to practical use.
本発明はこのような課題を解決するために、X線透視撮影用の被検者圧迫装置として、X線透視撮影台の可動テーブル上に俯臥した被検者の腹部圧迫用空気枕と、 In order to solve such a problem, the present invention, as a subject compression device for X-ray fluoroscopic imaging, an air pillow for abdominal compression of a subject dressed on a movable table of a fluoroscopic imaging table,

両電磁弁に対応する開閉スイッチの一対を備えた操作盤とから成り、 It consists of an operation panel with a pair of open / close switches corresponding to both solenoid valves,
撮影者が操作室からその操作盤の開閉スイッチを択一的に開閉操作して、上記空気枕を遠隔的に膨張又は収縮させるように定めたことを特徴とするものである。 The photographer selectively opens and closes the opening / closing switch of the operation panel from the operation room, so that the air pillow is remotely expanded or contracted.
本発明の請求項1に特定具体化された上記構成によれば、X線透視撮影台の可動テーブル上に俯臥した被検者の腹部を、その膨張される空気枕によって安全裡に圧迫することができ、各種のX線透視撮影台へ自由自在に後付け汎用し得る利便性がある。
According to the configuration specifically embodied in
しかも、その空気枕への空気給排源となる真空ポンプは、リニアーモーターでの往復駆動ピストン式として、作動音が静かであり、小型コンパクトに軽量化し得るほか、その吐出管路に介在する空気枕膨張用電磁弁と吸入管路に介在する空気枕収縮用電磁弁とが、これらに対応する各別な開閉スイッチの押圧操作によって開閉され、空気枕を膨張又は収縮させるようになっているため、その操作を極めて簡単に便利良く行なえ、特に優れた応答性能により空気枕の膨張度や、延いては造影剤層の厚みを正確に微調整できる効果がある。 Moreover, the vacuum pump that is the air supply / exhaust source to the air pillow is a reciprocating drive piston type with a linear motor, which has a quiet operation sound, can be reduced in size and weight, and air intervened in its discharge pipe The pillow expansion solenoid valve and the air pillow contraction solenoid valve interposed in the suction pipe are opened and closed by pressing the corresponding opening / closing switches to expand or contract the air pillow. The operation can be performed very easily and conveniently, and has an effect that the degree of expansion of the air pillow and the thickness of the contrast medium layer can be precisely finely adjusted with particularly excellent response performance.
又、請求項2の構成を採用するならば、真空ポンプから両電磁弁を経て三方型管継手までの配管系統を、小型コンパクトにユニット化することができ、消音効果や電磁波のカット効果に役立つほか、カバーケースを持ち運ぶことによって、撮影室内の希望個所へ自由自在に設置使用し得る効果もある。 Moreover, if the structure of Claim 2 is employ | adopted, the piping system from a vacuum pump to both three-way type joints via both solenoid valves can be unitized in a small and compact unit, which is useful for a silencing effect and an electromagnetic wave cutting effect. In addition, by carrying the cover case, there is an effect that it can be freely installed and used at a desired location in the photographing room.
更に、請求項3や請求項4の構成を採用するならば、複数の空気枕収納袋が区画形成されたマットの使用により、各種のX線透視撮影台へますます便利良く後付け汎用することができ、被検者の身長差にも対応し得る効果がある。 Furthermore, if the structure of claim 3 or claim 4 is adopted, the use of a mat in which a plurality of air pillow storage bags are partitioned can be used for various X-ray fluoroscopic imaging tables more conveniently and later. It is possible to cope with the height difference of subjects.
以下、図面に基いて本発明の具体的構成を詳述すると、そのX線透視撮影用被検者圧迫装置の第1実施形態を示した図1〜10において、(10)はX線を透過し得るポリウレタンなどの合成樹脂やゴム、その他の伸縮材から例えば直径:約250mmの円形や、約200mm×250mmの角形に作成された空気枕であり、これからは1本のフレキシブルチューブから成る延長給排管路(11)が導出している。 Hereinafter, the specific configuration of the present invention will be described in detail with reference to the drawings. In FIGS. 1 to 10 showing the first embodiment of the X-ray fluoroscopic subject compression apparatus, (10) transmits X-rays. This is an air pillow made from synthetic resin such as polyurethane, rubber, and other elastic materials, for example, a circular shape with a diameter of about 250 mm or a square with a size of about 200 mm x 250 mm. An exhaust pipe (11) is led out.
他方、(12)は上記空気枕(10)への空気給排源となるリニアー往復駆動ピストン式真空ポンプであって、その詳細を図示省略してあるが、モーターと圧縮部との一体構造になったシリンダーの内部を、ピストン(可動鉄芯)だけが電磁石の吸引力とスプリングの復元力により、電源周波数に同期した回数のもとで往復運動する。 On the other hand, (12) is a linear reciprocating drive piston type vacuum pump that serves as an air supply / exhaust source for the air pillow (10), the details of which are omitted in the figure, but with an integrated structure of the motor and the compression unit Inside the cylinder, only the piston (movable iron core) reciprocates within the number of times synchronized with the power frequency by the attractive force of the electromagnet and the restoring force of the spring.
つまり、電磁力が働いて、可動鉄芯と一体のピストンがスプリングを圧縮し乍ら吸引された時、吸入弁からシリンダーの内部へ空気を吸入する一方、電磁力が切れ、上記圧縮されていたスプリングの復元力により、ピストンが押し戻された時、吐出弁からシリンダーの外部へ圧縮空気を吐出するようになっている。 In other words, when the electromagnetic force works and the piston integrated with the movable iron core compresses the spring and sucks it, the air is sucked into the cylinder from the suction valve, while the electromagnetic force is cut and the compression is performed. When the piston is pushed back by the restoring force of the spring, compressed air is discharged from the discharge valve to the outside of the cylinder.
因みに、このような真空ポンプ(12)の好ましい仕様としては、吐出空気量が1分当り25リットル、到達真空度が−600mmHg、重量が5kgである。(13)(14)はその真空ポンプ(12)のシリンダーから並列状態に導出された吐出管路と吸入管路との一対であり、何れもフレキシブルチューブから成る。 Incidentally, as a preferable specification of such a vacuum pump (12), the discharge air amount is 25 liters per minute, the ultimate vacuum is -600 mmHg, and the weight is 5 kg. (13) and (14) are a pair of a discharge pipe and a suction pipe led out in parallel from the cylinder of the vacuum pump (12), each of which consists of a flexible tube.

It is fixedly installed via a rubber seat (16) for vibration isolation. (17) is a plurality of columns vertically suspended as a positional relationship surrounding the vacuum pump (12) from the installation base plate (15), and an aluminum alloy top plate (18 ) Is assembled and fixed.
(19)は上記吐出管路(13)の中途部に介挿された空気枕膨張用電磁弁、(20)は上記吸入管路(14)の中途部に介挿された空気枕収縮用電磁弁であり、これらは何れも消音器(21)(22)を備えた互いに同じ製品として、上記天板(18)の上面へ相反する方向性の並列状態に取り付け固定されている。 (19) is an air pillow expansion solenoid valve inserted in the midway part of the discharge pipe (13), and (20) is an air pillow contraction electromagnetic wave inserted in the midway part of the suction pipe (14). These are valves, both of which are mounted and fixed in the parallel state of the opposite direction to the upper surface of the top plate (18) as the same product provided with silencers (21) and (22).
そして、上記吐出管路(13)並びに吸入管路(14)の両先端部と、上記空気枕(10)から導出する延長給排管路(11)の先端部とが、三方型の管継手(23)を介して連通接続されており、上記真空ポンプ(12)の吐出作用による空気枕(10)の膨張状態と、同じく真空ポンプ(12)の吸入作用による空気枕(10)の扁平な収縮状態とを得られるようになっている。 And both the front-end | tip parts of the said discharge pipe line (13) and the suction pipe line (14), and the front-end | tip part of the extension supply / exhaust pipe line (11) derived | led-out from the said air pillow (10) are three-way type pipe joints The air pillow (10) is in an expanded state due to the discharge action of the vacuum pump (12), and the air pillow (10) is flat due to the suction action of the vacuum pump (12). The contracted state can be obtained.
(24)はアルミ合金から断面倒立U字型に造形されたカバーケースであって、その上面には把手(25)が取り付けられている一方、同じくカバーケース(24)の下端部が複数のビス(26)を介して、上記台板(15)へ組み付け固定されることにより、その台板(15)上の真空ポンプ(12)と両電磁弁(19)(20)並びに管継手(23)を被覆している。 (24) is a cover case that is shaped from an aluminum alloy into an inverted U-shaped cross section. A handle (25) is attached to the upper surface of the cover case, and the lower end of the cover case (24) is a plurality of screws. By being assembled and fixed to the base plate (15) via (26), the vacuum pump (12), both solenoid valves (19) (20) and pipe joint (23) on the base plate (15) Is covered.
つまり、上記真空ポンプ(12)から両電磁弁(19)(20)を経て三方型管継手(23)までの配管系統が、共通のカバーケース(24)に内蔵されたユニット体として、その全体を把手(25)により持ち運ぶことができるようになっているのである。その場合、両電磁弁(19)(20)を図1から示唆されるように、台板(15)への並列状態に固定設置して、上記カバーケース(24)を背丈の低く扁平化しても良い。 That is, the piping system from the vacuum pump (12) through the two solenoid valves (19) and (20) to the three-way pipe joint (23) as a unit body built in a common cover case (24) Can be carried by a handle (25). In that case, as suggested by FIG. 1, both solenoid valves (19) and (20) are fixedly installed in parallel to the base plate (15), and the cover case (24) is flattened to a low height. Also good.
(27)は上記真空ポンプ(12)と両電磁弁(19)(20)からのリード線(図示省略)を電気的に接続するコネクター、(28)は上記した1本の延長給排管路(11)を導通するための口金であり、その口金(28)とコネクター(27)との何れも上記カバーケース(24)に嵌め付け固定されている。上記延長給排管路(11)の中途部には着脱自在のカプラー(29)を介挿設置することが好ましい。 (27) is a connector for electrically connecting the lead wire (not shown) from the vacuum pump (12) and the solenoid valves (19) and (20), and (28) is the one extended supply / exhaust conduit described above. A base for conducting (11), and both the base (28) and the connector (27) are fitted and fixed to the cover case (24). It is preferable to install a detachable coupler (29) in the middle of the extended supply / discharge line (11).
更に、(30)は上記コネクター(27)に接続配線された操作盤であって、図2の制御回路に示すような電源スイッチ(31)のほか、上記空気枕膨張用電磁弁(19)の開閉スイッチ(32)と空気枕収縮用電磁弁(20)の開閉スイッチ(33)とを具備しており、これらを択一的に押圧操作して、各電磁弁(19)(20)を開放する一方、その押圧操作手を離せば、各電磁弁(19)(20)が閉鎖するようになっている。(34)はヒューズ、(35)は電源コンセントへの差込み配線プラグである。 Further, (30) is an operation panel connected and wired to the connector (27). In addition to the power switch (31) as shown in the control circuit of FIG. 2, the air pillow expansion solenoid valve (19) is provided. An open / close switch (32) and an open / close switch (33) of the air pillow contraction solenoid valve (20) are provided, and these solenoid valves (19) and (20) are opened by alternatively pressing them. On the other hand, when the pressing operation hand is released, the electromagnetic valves (19) and (20) are closed. (34) is a fuse, and (35) is an insertion wiring plug to a power outlet.
図9、10は本発明に係る被検者圧迫装置の使用状態を示しており、(A)は撮影室(R1)内に据え付けられた消化器官診断用のX線透視撮影台であって、X線管支持枠(36)に支持されたX線管(37)と、被検者(M)を載置する可動テーブル(38)と、その可動テーブル(38)を挟む如く、上記X線管(37)と対向位置するイメージインテンシファイアー(39)並びに脚台(40)とを備えている。 9 and 10 show the use state of the subject compression apparatus according to the present invention, and (A) is an X-ray fluoroscopic imaging table for diagnosis of digestive organs installed in the imaging room (R1), The X-ray tube (37) supported by the X-ray tube support frame (36), the movable table (38) on which the subject (M) is placed, and the X-ray so as to sandwich the movable table (38). An image intensifier (39) and a leg base (40) facing the tube (37) are provided.
但し、可動テーブル(38)の上面にはマット(41)が固定状態に敷設されており、そのマット(41)上へ被検者(M)が俯臥位として載置するようになっている。マット(41)は上記空気枕(10)の膨張と収縮に追従し得る薄肉なゴムや合成樹脂などから成り、しかもこれには空気枕(10)を収納し得る複数の空気枕収納袋(42a)(42b)が、上記可動テーブル(38)の長手方向に沿う並列状態として区画形成されている。 However, a mat (41) is laid in a fixed state on the upper surface of the movable table (38), and the subject (M) is placed on the mat (41) in a prone position. The mat (41) is made of a thin rubber or synthetic resin that can follow the expansion and contraction of the air pillow (10), and further includes a plurality of air pillow storage bags (42a) that can store the air pillow (10). ) (42b) is defined as a parallel state along the longitudinal direction of the movable table (38).
上記可動テーブル(38)のマット(41)上へ俯臥した被検者(M)に対しては、公知のようにX線透視撮影台(A)のX線管(37)からX線が照射され、その被検者(M)を透過したX線像は、イメージインテンシファイアー(39)によって光学像に変換され、その光学像をX線テレビカメラにより撮影し、その映像が撮影室(R1)に隣接する操作室(R2)のテレビモニター(43)へ、透視像として表示されるため、これを操作者が観察し乍ら、上記可動テーブル(38)を作動制御することになる。 As is well known, X-rays are radiated from the X-ray tube (37) of the X-ray fluoroscopic imaging table (A) to the subject (M) leaning on the mat (41) of the movable table (38). Then, the X-ray image transmitted through the subject (M) is converted into an optical image by the image intensifier (39), and the optical image is captured by the X-ray TV camera, and the image is captured in the imaging room (R1). ) Is displayed as a fluoroscopic image on the television monitor (43) in the operation room (R2) adjacent to the operation room (R2), the operation of the movable table (38) is controlled while the operator observes this.
そこで、本発明を使用するに当っては、その真空ポンプ(12)と両電磁弁(19)(20)並びに管継手(23)がユニット体として内蔵されたカバーケース(24)を、撮影室(R1)内の適当個所に設置して、これから導出配管された空気枕(10)を上記マット(41)における空気枕収納袋(42a)(42b)の何れか一方へ、出し入れ自在に挿入セットする一方、操作盤(30)を操作室(R2)内の操作しやすい個所に設置する。 Therefore, when the present invention is used, a cover case (24) in which the vacuum pump (12), both solenoid valves (19) and (20), and a pipe joint (23) are incorporated as a unit body is provided in the photographing room. (R1) is installed at an appropriate place, and the air pillow (10) led out from the air pillow (10) is inserted and set freely into and out of one of the air pillow storage bags (42a) and (42b) in the mat (41). On the other hand, the operation panel (30) is installed in an easy-to-operate place in the operation room (R2).
その場合、マット(41)の空気枕収納袋(42a)(42b)は複数として、可動テーブル(38)の長手方向に沿う並列状態にあるため、被検者(M)の身長に応じて、その空気枕収納袋(42a)(42b)の何れか一方を選択使用することにより、空気枕(10)を被検者(M)の消化器官に対応位置させる。 In that case, since the air pillow storage bags (42a) and (42b) of the mat (41) are in a parallel state along the longitudinal direction of the movable table (38), depending on the height of the subject (M), By selectively using one of the air pillow storage bags (42a) and (42b), the air pillow (10) is positioned corresponding to the digestive organ of the subject (M).
このような準備後、操作者が操作盤(30)における電源スイッチ(31)のほか、空気枕膨張用電磁弁(19)の開閉スイッチ(32)を押圧操作すれば、上記真空ポンプ(12)の吐出管路(13)から空気枕(10)へ供給される圧縮空気により、空気枕(10)が膨張して、被検者(M)の腹部を圧迫するため、その俯臥位にある被検者(M)の体重とも相俟ち、消化器官の造影剤(バリューム)が全体的に拡散した状態となり、その消化器官の正確な診断に役立つ。 After such preparation, if the operator presses the open / close switch (32) of the air pillow expansion solenoid valve (19) in addition to the power switch (31) in the operation panel (30), the vacuum pump (12) will be described. The compressed air supplied from the discharge pipe (13) to the air pillow (10) causes the air pillow (10) to expand and press the abdomen of the subject (M). Together with the body weight of the examiner (M), the contrast agent (value) of the digestive tract is diffused as a whole, which is useful for accurate diagnosis of the digestive tract.
その際、空気枕膨張用電磁弁(19)の開閉スイッチ(32)から押圧操作手を離せば、その電磁弁(19)により圧縮空気の吐出管路(13)が自づと閉鎖されて、上記空気枕(10)の膨張度が停止する一方、これと別個な空気枕収縮用電磁弁(20)の開閉スイッチ(33)を同様に押圧操作すれば、その押圧操作時間だけ空気枕(10)から真空ポンプ(12)へ、上記空気が吸入され、その押圧操作手を離しても空気枕(10)の収縮度が即刻停止するため、造影剤層の厚みを容易に正しく微調整することができ、その操作性と応答性に著しく優れる。 At that time, if the pressing hand is released from the open / close switch (32) of the air pillow expansion electromagnetic valve (19), the compressed air discharge line (13) is closed by the electromagnetic valve (19). While the degree of expansion of the air pillow (10) is stopped, if the opening / closing switch (33) of the separate air pillow contracting solenoid valve (20) is pressed in the same manner, the air pillow (10 ) To the vacuum pump (12), the air pillow (10) contracts immediately even if the pressing operation is released, and the thickness of the contrast medium layer can be easily and finely adjusted. It is extremely excellent in operability and responsiveness.
尚、操作盤(30)における上記空気枕収縮用電磁弁(20)の開閉スイッチ(33)を押圧操作することにより、空気枕(10)をすばやく扁平な収縮状態に復元できることは言うまでもない。 Needless to say, the air pillow (10) can be quickly restored to a flat contracted state by pressing the open / close switch (33) of the air pillow contracting solenoid valve (20) on the operation panel (30).
