Description

【0001】
【産業上の利用分野】
本願発明は、歯科診療において、術中、術直後に撮影したX線フィルムを即時現像処理するための簡易現像器、およびその簡易現像器に用いるためのフィルムハンガーに関するものである。
【0002】
【従来の技術】
近年、歯科診療において、X線の利用は極めて頻度が高く、日常的にX線撮影が行われ、画像診断や画像処理、X線フィルムの現像処理についても、様々な方法が利用されている。
【0003】
最近、X線撮影の頻度の増加に伴い、自動現像器の使用も一般的となり、歯科診療の能率向上に役立っている。しかしながら、通常、一般のX線撮影に伴う自動現像器による現像処理は極めて便利で能率的である反面、自動現像は、現像、定着、水洗、乾燥の各段階を自動的に連続処理するため、一定の処理時間を必要とし、意図的に現像処理時間を短縮することができない。
【0004】
日常、歯科診療において最も多く使用される歯科用標準型X線フィルムは3cm×4cmの小型サイズのフィルムであるが、これを自動現像処理すると、機種により異なるが、現像から乾燥まで約3〜5分の時間を要する。
【0005】
歯科診療においては、処置、手術の途中でX線撮影を行い、その結果をフィルム上で確認しつつ次のステップに移るため、術中や術直後のX線撮影は臨床歯科医にとって必要かつ有効な手段である。したがって、X線検査の結果を一刻でも早く確認したい場合は、自動現像以外の即時現像処理が必要となる。
【0006】
現在、汎用されている即時現像処理方法は種々あるが、よく使用されているものにインスタント現像法がある。これは、ビニール袋にパックされた専用フィルムを使用し、撮影後、ビニール袋内に注射器で吸引した現像定着液を注入したり、容器に入れた現像定着液を加圧注入し、指定された現像定着の時間が経過した後、ビニールパックを破り、フィルムを取り出して、診断後、水洗乾燥する。
【0007】
この方法は、現像定着時間30秒と短時間の処理が可能で、暗室や暗箱が不要で、明室処理ができるという長所がある。その反面、注入針の誤刺、針によるフィルム面の傷や、パックから取り出す際に起こりがちな薬液の飛散による衣服や什器備品の汚染、手指、皮膚の汚染やかぶれ等の不快事故は、しばしば経験されるところである。
【0008】
【発明が解決しようとする課題】
従前より、一般に行われている手現像(マニュアル現像)は、特別な装置を必要とせず最も簡便な方法であるが、上述のインスタント現像と同じような薬液による汚染等の不快事故が起こり得るものである。
【0009】
特に、マニュアル現像の場合、フィルムを薬液に浸すためにピンセットやクリップ等でフィルムを保持する必要があるが、薬液槽内にフィルムが保持器具から外れて脱落したり、クリップ等のピンチ跡や保持器具による傷は正確な診断の妨げになるばかりでなく、診療資料としての価値を著しく損なうことになる。
【0010】
本願発明は、簡便かつ迅速なX線フィルム現像処理方法として、従前より行われているマニュアル現像法の欠点や問題点を解決し、より安全で確実なものとするための簡易現像器具を開発し提供するものである。
【0011】
【課題を解決するための手段】
本願の請求項1に係る発明は、撮影したX線フィルムを取り付けるためのフィルムハンガーと、フィルムハンガーに取り付けたX線フィルムの現像、定着、水洗を行うための液体を入れる複数の槽と、これらの槽の受け皿となるトレーとからなる歯科用X線フィルム簡易現像器であり、フィルムハンガーが、縦横の内寸をX線フィルムの縦横の寸法よりわずかに小さくしたほぼ矩形の枠体と、この枠体の前面にX線フィルムを取り囲むように複数配置した保持突起と、枠体の上方に設けられ枠体の横幅より十分長い桿状のハンドル部とからなり、保持突起にX線フィルム離脱防止用の頭部とその内側に頭部より細い挟部を形成し、複数の保持突起の挟部の内側に形成される四角形の寸法をX線フィルムの寸法とほぼ等しくしてあることを特徴とする。
【0012】
請求項2は、請求項1の歯科用X線フィルム簡易現像器について、複数の槽の形態を限定したものであり、槽がほぼ四角形の箱型であり、横幅をフィルムハンガーのハンドル部の長さより短くし、横幅方向に対向する上端部にハンドル部を受けるための一定の長さと深さの一対のかぎこみ(切欠き部)を形成したものである。
【0013】
請求項3に係る発明は、上述の請求項1の簡易現像器に使用するための簡易現像器用フィルムハンガーであり、縦横の内寸をX線フィルムの縦横の寸法よりわずかに小さくしたほぼ矩形の枠体と、枠体の前面にX線フィルムの寸法に応じて取り付けられるX線フィルムを取り囲むように複数配置した保持突起と、枠体の上方に設けられ枠体の横幅より十分長い桿状のハンドル部とからなり、保持突起にはX線フィルム離脱防止用の頭部の内側に頭部より細い挟部を形成し、複数の保持突起の挟部の内側に形成される四角形の寸法を前記X線フィルムの寸法とほぼ等しくしてあることを特徴とする。
【0014】
請求項4は請求項3に係るフィルムハンガーにおいて、ハンドル部の一端にフックを設けた場合を限定したものである。
【0016】
【実施例】
図1〜図4は、それぞれ本願発明の簡易現像器の実施例における使用状態、フィルムハンガーの形態、現像槽等の槽の形態、およびトレーの形態の一例を示したものである。
【0017】
本実施例における簡易現像器および各部品の構成および特徴は以下の通りである。
【0018】
(1) フィルムハンガー(図2参照)
本実施例におけるフィルムハンガー1は合成樹脂を素材とし、合成樹脂製の枠体2とフィルム保持のためのフィルム保持部および捍状のハンドル部4により構成される。ハンドル部4の一端には乾燥等の用に供するためのフック5(フック5部分を引っ掛けて吊るすことができる)を設けている。
【0019】
▲1▼ フィルム保持部
本実施例におけるフィルム保持部は、ソロバン玉を組み合わせたような形態の頭部3aと挟部3bを有する保持突起3を6〜8個形成し、上下テーパー部の中間の挟部3bでフィルムFを多少のゆとりをもって把持できるようになっている(図1参照)。
【0020】
歯科用標準型X線フィルムFは、合成樹脂製の薄い平板で弾力性に富み、3cm×4cmに統一されている。フィルムFをこのフィルム保持部に取り付ける操作は、まず撮影された歯科用標準型X線フィルムFを包装から取り出し、フィルム保持部の保持突起3で囲まれた枠体2の中央にフィルムFを置き、清潔な手指でフィルムFを軽く押すと、フィルムFは保持突起3のテーパーにガイドされて挟部3bに押し込まれ、フィルムFの弾力によって挟部3bに挟み込まれる。
【0021】
一旦、挟部3bに挟み込まれたフィルムFは、枠体2の裏側から取付け方向に対し、反対の方向に押し出さないかぎり、保持部から脱離することはない。
【0022】
このように、本機構は歯科用標準型X線フィルムF自体の持つ弾力性と曲げに対する復元力を利用したものである。したがって、他のフィルム保持器具のようにピンセットで挟んだり、クリップや鉗子でピンチしたりするものと違って、フィルムに傷をつけたり、挟んだ部分が薬液に触れないために生ずる現像むらやフィルムの槽内での脱落を生じることがない。
【0023】
暗室や暗箱内は、非常に暗いので、手探り状態での操作が多く、本器具のようにフィルムの取付けが簡単で、しかも操作が容易で確実な器具の使用は現像処理作業を楽にするものである。
【0024】
▲2▼ ハンドル部
枠体2の上部に設けた桿状のハンドル部4は、その両端が左右とも枠体2の両端より長く、現像槽、定着槽、水洗槽の各槽6の幅より長い(図1参照)。そのため、現像処理に際して、フィルムハンガー1は、各槽6の所定の位置にフィルム保持部を中央にして槽6をまたぐように安定した状態で固定され、ハンドル部4両端の延長された端部が槽6の上端からはみ出した状態で、槽6上中央に安定する。
【0025】
この時、フィルム保持部は、現像槽、定着槽、水洗槽の各槽6内に吊るされた状態になり、フィルム保持部のみが薬液に浸されてハンドル部4には薬液が付着することがない。このため、フィルムハンガー1を現像槽6a、定着槽6b、水洗槽6cの各槽6(図4(b) 参照)に順次移送する際に、この長めに設定された桿状のハンドル部4を手で持って移送することができるので、手に薬液が付着するのを防止でき、現像処理中にほとんど手を汚すことはない。あるいは、暗室から診療室等へのフィルムの移送や補助者と歯科医師間相互の手渡しに際しても、このハンドル部4の両端に延長された部分を持って手渡しができるので、手の清潔な状態が維持される。
【0026】
また、現像、定着の操作中、端部を持ち、ハンドル部4の長軸を中心とした回転運動をごく小さく行い、槽6内の薬液を攪拌し、反応を促進したり、現像むらや定着むらを防止することができる。
【0027】
(2) 現像槽、定着槽および水洗槽(図3参照)
本実施例において、合成樹脂製の各槽6は、同一の形態の概ね四角形の箱型で、横幅は前記ハンドル部4の両端の長さより短く、槽6の中央にフィルム保持部が吊り下げられる。槽6の上端部中央には、ハンドル部4の桿を安定した状態で固定するための一定の長さと深さのかぎこみ7(切欠き部)を形成する。このかぎこみ7は、複数のフィルムを同時処理するため、必要とするフィルムハンガー1の厚みの倍数以上の長さとなる。このかぎこみ7によって、現像処理操作の際、フィルムハンガー1が槽6の中央に正しくガイドされ、常に安定した位置が保たれ、かぎこみ7は暗室や暗箱内での操作の上でも有用なものとなる。
【0028】
なお、図中、符合10は槽6の上部に設けたつば部分、11は槽6の内面に設けた目盛線を表している。
【0029】
(3) トレー(図4参照)
トレー8は、現像処理中や、前準備における薬液の滴下や飛散、オーバーフローといった形での液の漏出を受け止める受け皿の役目を有し、作業場所周辺の汚染を防止する。
【0030】
本実施例におけるトレー8の構造は、合成樹脂製の一般的な形状をしたトレーの底板8a上面に、各槽6の底部が位置する部分を取り囲むようにガイド用突起9を必要個数設置したものである。各槽6は、このガイド用突起9に囲まれた位置に納まり、各槽6(6a,6b,6c)の位置や間隔を一定に保つことができる。このように、槽6の位置や間隔が常に一定していることは、非常に暗い条件下における暗室や暗箱内での操作を楽にする。
【0031】
このガイド用突起9は、テーパーの付いた円錐台形で、ブラシ洗浄等の清掃を容易にする。また、このガイド用突起9によって、持ち運びや移動等の急な傾斜や同様にも安定し、槽6の滑りや転覆を防止する。
【0032】
以上(1) 〜(3) の各部品を一組の器具として組み合わせて簡易現像器として使用することができ、図1はフィルムハンガー1に歯科用標準X線フィルムFを取り付け、現像槽6a等の槽6の液体中(現像液、定着液または水洗用の水等)に浸した状態を示したものである。図に示すように、フィルムハンガー1のハンドル部4の桿の両端部が槽6のかぎこみ7間に架け渡された状態で、フィルム保持部が垂下し、槽6の液体中に浸っている。槽6はトレー8の底板9上に載せられており、ガイド用突起9で水平位置が固定されている。
【0033】
【発明の効果】
▲1▼ 本願発明の簡易現像器は、歯科用X線フィルムの現像において、自動現像器のような特別な装置を必要とせず、即時の現像処理を可能とするものであり、かつ従来のマニュアル現像やインスタント現像における薬液の飛散等による汚染その他の不快事故のない安全、確実な現像処理が可能である。
【0034】
▲2▼ 本願発明の簡易現像器およびフィルムハンガーによれば、X線フィルムをフィルム自体の弾力性と復元力を利用して簡単に装着することができ、従来のマニュアル現像の場合のようなピンセットやクリップ等によるX線フィルムの傷や現像むらが生じず、また薬液槽内に落としたりする恐れもないため、正確な診断を可能とし、診療資料としての価値を損なわせることもない。また、暗室や暗箱内での手探り状態での操作が容易になる。
【0035】
▲3▼ 本願発明の簡易現像器およびフィルムハンガーによれば、フィルム保持部は、現像槽等の各槽内に吊るされた状態になり、フィルム保持部のみが薬液に浸されてハンドル部には薬液が付着することがない。したがって、フィルムハンガーを各槽に順次移送する際に、薬液の付着しないハンドル部を持って移送することができ、現像処理中にほとんど手を汚すことがない。また、暗室から診療室等へのフィルムの移送や補助者と歯科医師間相互の手渡しに際しても、このハンドル部の両端に延長された部分を持って手渡しができるので、手の清潔な状態が維持される。

[Industrial application fields]
The present invention provides a dental practice, in which relates intraoperative, simple developing device for the extemporaneous developing the captured X-ray film immediately after surgery, and the film hanger over for use in the simple development unit.
[0002]
[Prior art]
In recent years, X-rays are used very frequently in dental practice, and X-ray imaging is performed on a daily basis. Various methods are also used for image diagnosis, image processing, and X-ray film development processing.
[0003]
Recently, with the increase in the frequency of X-ray photography, the use of an automatic developing device has become common, which has helped improve the efficiency of dental care. However, the development process using an automatic developing device associated with general X-ray photography is usually very convenient and efficient, but the automatic development automatically and continuously processes each stage of development, fixing, washing and drying. A certain processing time is required, and the development processing time cannot be intentionally shortened.
[0004]
The standard dental X-ray film most frequently used in daily dental practice is a 3 cm x 4 cm small-sized film, but when this is automatically developed, it varies depending on the model, but from developing to drying is approximately 3-5. It takes a minute.
[0005]
In dental practice, X-rays are taken in the middle of treatment and surgery, and the results are confirmed on the film before moving to the next step. Therefore, X-rays during and immediately after surgery are necessary and effective for clinical dentists. Means. Therefore, when it is desired to confirm the result of the X-ray inspection as soon as possible, immediate development processing other than automatic development is required.
[0006]
At present, there are various types of immediate development processing methods that are widely used, and an instant development method is often used. This is done using a special film packed in a plastic bag. After shooting, the developer fixer sucked with a syringe is injected into the plastic bag, or the developer fixer in a container is injected under pressure. After the development and fixing time has elapsed, the plastic pack is broken, the film is taken out, washed, and dried after diagnosis.
[0007]
This method has an advantage that it can be processed in a short time of 30 seconds as a developing and fixing time, does not require a dark room or a dark box, and can perform a bright room process. On the other hand, unpleasant accidents such as needle punctures, scratches on the film surface due to needles, contamination of clothes and fixtures due to splashes of chemicals that tend to occur when removing from the pack, contamination of fingers and skin, and rashes are often encountered. It is where you are experienced.
[0008]
[Problems to be solved by the invention]
Conventionally, hand development (manual development), which is generally performed, is the simplest method without the need for special equipment, but can cause unpleasant accidents such as contamination with chemicals similar to the above-mentioned instant development. It is.
[0009]
In particular, in manual development, it is necessary to hold the film with tweezers or clips in order to immerse the film in the chemical solution. Instrumental wounds not only interfere with accurate diagnosis, but also significantly impair the value of medical materials.
[0010]
The present invention has developed a simple developing device that solves the drawbacks and problems of the conventional manual developing method as a simple and rapid X-ray film developing method, and makes it safer and more reliable. It is to provide.
[0011]

【Example】
1 to 4 show an example of the usage state, the form of a film hanger, the form of a tank such as a developing tank, and the form of a tray, respectively, in an embodiment of the simple developing device of the present invention.
[0017]
The configuration and characteristics of the simple developing device and each component in the present embodiment are as follows.
[0018]
(1) Film hanger (see Fig. 2)
The film hanger 1 in this embodiment is made of a synthetic resin, and is composed of a synthetic resin frame 2, a film holding part for holding the film, and a bowl-like handle part 4. One end of the handle portion 4 is provided with a hook 5 (which can be hooked and suspended) for use in drying or the like.
[0019]
(1) Film holding part The film holding part in this embodiment is formed with 6 to 8 holding projections 3 having a head 3a and a sandwiching part 3b in the form of a combination of abacus balls, between the upper and lower taper parts. The film F can be gripped with some clearance by the sandwiching portion 3b (see FIG. 1).
[0020]
The standard dental X-ray film F is a thin flat plate made of a synthetic resin, rich in elasticity, and standardized to 3 cm × 4 cm. The operation of attaching the film F to the film holding part is as follows. First, the photographed standard dental X-ray film F is taken out of the packaging, and the film F is placed in the center of the frame 2 surrounded by the holding projections 3 of the film holding part. When the film F is lightly pressed with clean fingers, the film F is guided by the taper of the holding projection 3 and pushed into the pinching portion 3b, and is pinched by the pinching portion 3b by the elasticity of the film F.
[0021]
The film F once sandwiched between the sandwiching portions 3b is not detached from the holding portion unless it is pushed out from the back side of the frame body 2 in the direction opposite to the mounting direction.
[0022]
As described above, this mechanism uses the elasticity and bending restoring force of the standard dental X-ray film F itself. Therefore, unlike other film holders that are pinched with tweezers or pinched with clips or forceps, the film is scratched or the unevenness of development that occurs because the pinched part does not touch the chemical solution. There is no dropout in the tank.
[0023]
The dark room and dark box are very dark, so there are many groping operations, and it is easy to install the film as in this device, and the use of a device that is easy to operate and reliable makes development processing easier. is there.
[0024]
(2) The hook-like handle portion 4 provided on the upper portion of the handle portion frame body 2 is longer at both ends than the both ends of the frame body 2 and longer than the width of each of the developing tank, the fixing tank, and the washing tank ( (See FIG. 1). Therefore, during the development process, the film hanger 1 is fixed in a stable state so as to straddle the tank 6 with the film holding part at the center in a predetermined position of each tank 6, and the extended ends of both ends of the handle part 4 are In a state where it protrudes from the upper end of the tank 6, it stabilizes in the center on the tank 6.
[0025]
At this time, the film holding part is suspended in the developing tank, the fixing tank, and the washing tank 6, and only the film holding part is immersed in the chemical solution, and the chemical solution adheres to the handle portion 4. Absent. Therefore, when the film hanger 1 is sequentially transferred to each of the developing tank 6a, the fixing tank 6b, and the washing tank 6c (see FIG. 4B), the long handle-shaped handle portion 4 is used. Therefore, it is possible to prevent the chemical solution from adhering to the hand, and the hand is hardly soiled during the developing process. Alternatively, when the film is transferred from the dark room to the clinic or the like, or between the assistant and the dentist, the hand can be handed with the extended portions at both ends of the handle portion 4, so that the hand is clean. Maintained.
[0026]
Further, during the development and fixing operations, the end portion is held, and the rotational movement around the long axis of the handle portion 4 is made very small, the chemical solution in the tank 6 is stirred, the reaction is promoted, and uneven development and fixing are performed. Unevenness can be prevented.
[0027]
(2) Developer tank, fixing tank and washing tank (see Fig. 3)
In this embodiment, each tank 6 made of synthetic resin has a substantially rectangular box shape having the same form, and the lateral width is shorter than the length of both ends of the handle part 4, and the film holding part is suspended from the center of the tank 6. . In the center of the upper end portion of the tank 6, a lock 7 (notch portion) having a certain length and depth for fixing the heel of the handle portion 4 in a stable state is formed. The hook 7 has a length more than a multiple of the required thickness of the film hanger 1 because a plurality of films are processed simultaneously. By this squeegee 7, the film hanger 1 is correctly guided to the center of the tank 6 during the development processing operation, and a stable position is always maintained. The sledge 7 is also useful for operation in a dark room or dark box. It becomes.
[0028]
In the figure, reference numeral 10 denotes a collar portion provided on the upper portion of the tank 6, and 11 denotes a scale line provided on the inner surface of the tank 6.
[0029]
(3) Tray (See Fig. 4)
The tray 8 serves as a tray that catches the leakage of liquid in the form of dripping, scattering, and overflowing of chemicals during the development process and in preparation, and prevents contamination around the work site.
[0030]
In the present embodiment, the tray 8 has a structure in which a necessary number of guide protrusions 9 are provided on the upper surface of a bottom plate 8a of a general tray made of synthetic resin so as to surround a portion where the bottom of each tank 6 is located. It is. Each tank 6 is housed in a position surrounded by the guide protrusions 9, and the positions and intervals of the tanks 6 (6a, 6b, 6c) can be kept constant. As described above, the constant position and interval of the tank 6 facilitate the operation in the dark room or dark box under extremely dark conditions.
[0031]
The guide protrusion 9 has a tapered truncated cone shape and facilitates cleaning such as brush cleaning. Further, the guide protrusion 9 stabilizes the steep inclination and the like such as carrying and moving, and prevents the tank 6 from slipping or overturning.
[0032]
The above components (1) to (3) can be combined as a set of tools and used as a simple developing device. FIG. 1 shows a film hanger 1 with a dental standard X-ray film F attached thereto, a developing tank 6a, etc. 2 shows a state of being immersed in a liquid (developer, fixing solution, water for washing, etc.). As shown in the figure, the film holding part hangs down and is immersed in the liquid in the tank 6 with both ends of the handle 4 of the film hanger 1 spanned between the hooks 7 of the tank 6. . The tank 6 is placed on the bottom plate 9 of the tray 8, and the horizontal position is fixed by the guide protrusion 9.
[0033]
【The invention's effect】
(1) The simple developing device of the present invention does not require a special device such as an automatic developing device in developing a dental X-ray film, and enables an immediate developing process, and a conventional manual. Safe and reliable development processing is possible without contamination and other unpleasant accidents due to the scattering of chemicals during development and instant development.
[0034]
(2) According to the simple developing device and film hanger of the present invention, the X-ray film can be easily mounted by utilizing the elasticity and restoring force of the film itself, and tweezers as in the case of conventional manual development. The X-ray film is not scratched or unevenly developed by a clip or clip, and is not likely to be dropped into the chemical bath. Therefore, accurate diagnosis is possible, and the value as a medical document is not impaired. In addition, it is easy to perform a groping operation in a dark room or a dark box.
[0035]
(3) According to the simple developing device and the film hanger of the present invention, the film holding part is suspended in each tank such as a developing tank, and only the film holding part is immersed in the chemical solution, The chemical solution will not adhere. Therefore, when the film hanger is sequentially transferred to each tank, the film hanger can be transferred with a handle portion to which no chemical solution adheres, and the hands are hardly soiled during the developing process. Also, when transferring the film from the dark room to the doctor's office, etc. or between the assistant and the dentist, the hand can be handed with the extended parts at both ends of the handle so that the hand is kept clean.
