- the backlight image and the front-side image are taken by the same photographing device 40 although the illumination state is different. Therefore, the positional relationship between the areas included in the backlight image and the front-side image is in a corresponding relationship.
- the inspection unit 30 is configured by a translucent plate. For this reason, an area (background area) where no medicine is arranged in the backlight image is brightly reflected in a state where light is transmitted. On the other hand, when the medicine does not have translucency, the area where the medicine is arranged in the backlight image is dark and appears almost black. Therefore, when the medicine is not translucent, the outline of the medicine can be derived by using the difference in brightness in the backlight image as a reference.
- a device that emits red light is employed as the back side illumination device 54. Therefore, when an R component image obtained by decomposing a backlight image into RGB is acquired, a shadow difference between the background portion and the drug portion clearly appears as shown in FIG. An image as shown in FIG. 12D is acquired by performing noise removal on the image of FIG. Thereafter, a region having a luminance lower than a predetermined luminance is extracted as a low luminance region in the image of FIG. 12D (see FIG. 12E). The contour line of the low luminance region extracted in this way can be derived as a line that forms the outer edge of the medicine (see FIG. 12F).
- the front side image is an image obtained by photographing the medicine on the inspection unit 30 from the front side, and the plate body forming the inspection unit 30 in addition to the medicine is in the background. Further, as described above, the positional relationship between the areas included in the backlight image and the front-side image has a corresponding relationship. Therefore, in the front side image, the region corresponding to the region surrounded by the outline of the medicine derived using the backlight image is an area corresponding to the medicine. Specifically, when a contour line as shown in FIG. 12 (f) is derived as described above, a region corresponding to a region surrounded by the contour line in the front-side image as shown in FIG. 12 (g). Is an area corresponding to a drug. Therefore, by extracting the region in the front-side image using the above-described contour line as an index, the medicine image can be obtained separately from the background image.
- the outline of the medicine can be derived relatively easily and accurately from the backlight image.
- the medicine has translucency, the medicine is not photographed as a shadow in the backlight image, and it becomes bright as if the light is transmitted in the same manner as the background portion. For this reason, it is difficult to derive an outline of a translucent drug based on the shadow difference in the backlight image (see FIG. 13B).
- the saturation is clearly defined between the area where the drug is arranged in the front image (hereinafter also referred to as “drug arrangement area”) and the other area (background area). It is different. Specifically, as shown in FIG. 13C, when an image related to the saturation component of the front-side image (hereinafter also referred to as “saturation image”) is acquired, the medicine placement region is clearly defined from the background region. Can be distinguished. That is, the luminance is greatly different between the medicine arrangement area and the background area, and the medicine arrangement area is higher in luminance than the background area.
- processing for deriving a high-brightness region on the basis of the luminance is performed on the image obtained by removing noise from the saturation image shown in FIG. 13C (see FIG. 13D) (see FIG. 13E).
- the drug placement region for the translucent drug can be distinguished from the background region.
- FIG. 13G by applying the contour line thus obtained to the backlight image, the image of the translucent drug can be cut out from the background image and extracted.
- the extracted image of the translucent drug can be registered in the master database as a master image for inspection.
- an inspection master image can be obtained by performing image processing according to a flowchart as shown in FIG. Specifically, first, in the front side image acquisition step of Step 2-1, a front side image as shown in FIG. 13A is acquired. Thereafter, in the saturation component extraction step of Step 2-2, an image (saturation component extraction image) obtained by extracting only the saturation component from the front side image is acquired.
- step 2-3 image processing for extracting a high luminance region (high luminance region) in the saturation component extraction image is performed (see FIG. 13E). Thereafter, the outer edge of the high luminance region is derived as a contour line (see FIG. 13F).
- a master image is acquired in the master image acquisition step of step 2-4. That is, image processing for superimposing the contour line acquired in step 2-3 on the front side image of FIG. 13A is performed. As a result, as shown in FIG. 13G, the region in which the medicine is reflected in the front image is surrounded by the outline.
- a master image can be acquired by cutting out a region surrounded by the contour line in the front image.
- step 2-5 when the master image is acquired in step 2-4, in step 2-5, the master image is registered in the master database in a state of being associated with the type of medicine. Thereby, a series of control flow is completed.

Abstract
Description
薬剤分包装置100は、入力された処方データに則って薬剤を分包して排出することができる装置である。薬剤分包装置100の本体の内部には、薬剤供給手段130、薬剤準備手段150、及び薬剤包装手段180が設けられている。
薬剤鑑査装置10は、分包紙に一服用分ずつ分包された状態で供給された鑑査対象の薬剤の数量及び種類を、一包ずつ鑑査する装置である。図2に示すように、薬剤鑑査装置10は、筐体10aの側面に鑑査対象の薬剤を導入するための導入部10bを有し、正面に操作パネル10cを有する。薬剤は、透光性を有する分包紙によって包装され、外部から視認可能な状態で薬剤鑑査装置10に供給される。また、薬剤鑑査装置10は、一服用分の薬剤を包装した分包袋が複数、連続するように形成された分包袋連続体の状態で分包袋を供給し、各分包袋について順次鑑査を行うことができる。
制御装置60は、薬剤の画像をマスター画像として蓄積した鑑査用データベース62を備えている。制御装置60は、鑑査用データベース62に登録されているマスター画像と、撮影装置40によって取得された薬剤の画像とをマッチングする処理(画像マッチング処理)を実行し、分包袋に処方通りに薬剤が包装されているか否かを鑑査する鑑査業務を実施することができる。具体的には、制御装置60は、分包袋に分包されている薬剤の種類についての鑑査(薬種照合鑑査)と、分包袋に包装されている薬剤の数量についての鑑査(数量照合鑑査)とを実施することができる。制御装置60は、薬種照合鑑査を実行することにより、分包されている薬剤が処方に合致する種類のものであるか否かの判定(薬種合致判定)に加え、画像マッチング処理により分包袋に包装されている薬剤と類似する薬剤(類似薬)が鑑査用データベース62に存在するか否かの判定(類似判定)を実行し、類似薬が存在する場合に警告を発することができる。すなわち、薬種照合鑑査を実行することにより、薬種合致判定及び類似判定が実施される。また、制御装置60は、数量照合鑑査を実施することにより、分包袋に包装されている薬剤の数量を検出し、処方通りの数量の薬剤が分包されているか否かの判定(数量判定)を実施することができる。
非限定モードによる類似判定は、鑑査用データベース62に登録されている全薬剤を参照範囲として実施される。非限定モードによる類似判定を実施した場合、鑑査用データベース62に登録されている全薬剤を対象として漏れなく類似判定の対象とすることができる。
準備薬限定モードによる類似判定を行う場合には、鑑査用データベース62の参照範囲を薬剤分包装置100に分包用として実装される薬剤として登録されている薬剤(以下、「準備薬」とも称す))の範囲内に限定して実施される(図5(a)参照)。ここで、準備薬には、薬剤分包装置100に分包用としてカセット等を用いて実装されている薬剤に加え、実装される薬剤として登録されている薬剤全般を含む。すなわち、準備薬には、薬剤分包装置100に実装しきれないものの別途カセット等に準備されている薬剤や、冷所保存が必要とされ薬剤分包装置への実装に備えてカセット等を用いて準備されている薬剤、分包用として手動薬剤供給部138に準備される薬剤(以下、「手撒薬剤」とも称す)のように実装されていないものの分包に用いられる薬剤等を含む概念である。
採用薬限定モードは、鑑査用データベース62に登録されている薬剤のうち、分包用として準備される薬剤として登録されている薬剤(以下、「採用薬」とも称す)の範囲内に限定して鑑査用データベース62を参照し、類似判定を実施する動作モードである(図5(b)参照)。ここで、採用薬とは、薬剤分包装置に分包用として実装して準備されている薬剤だけではなく、分包に用いられる薬剤として想定して登録された薬剤全般を含む概念である。具体的には、採用薬には、薬剤分包装置への実装用として実際に実装あるいは準備されている薬剤に加え、薬局等の当該施設内、又は薬局チェーン内において分包用として採用される薬剤全般が該当する。従って、薬剤分包装置100が手動薬剤供給部138を備えていないものである場合には、準備薬が採用薬に相当することになり、採用薬限定モードと準備薬限定モードとが実質的に同一の動作モードとなる。
同一分包薬限定モードは、鑑査用データベース62の参照範囲を分包袋内に包装されている薬剤の範囲内に限定する類似判定の動作モードである(図5(c)参照)。同一分包薬限定モードを選択することにより、鑑査用データベース62の参照範囲が非限定モードを選択した場合よりも大幅に限定される。これにより、類似薬が存在するとの警告がなされることを大幅に抑制し、鑑査業務の煩雑さを解消することができる。また、このようにして鑑査用データベース62の参照範囲を絞り込むことにより、類似判定に要する処理速度も向上させうる。
同一処方薬限定モードは、鑑査用データベース62の参照範囲を、同一患者の処方に対して作成された分包袋群において分包されている薬剤の範囲内に限定して実施する類似判定の動作モードである(図5(d)参照)。同一処方薬限定モードを選択した場合についても、鑑査用データベース62の参照範囲が非限定モードを選択した場合よりも大幅に限定され、類似薬が存在するとの警告が必要以上になされることを回避できる。また、鑑査業務の煩雑さを解消し、類似判定に要する処理速度も向上させうる。
処方履歴限定モードが選択された場合は、鑑査対象である分包袋に対応する患者についての処方履歴が登録されたデータベース(処方履歴データベース64)が参照され(図5(e)参照)、処方履歴として登録されている薬剤(以下、「既処方薬」とも称す)が特定される。処方履歴限定モードにおいては、鑑査用データベース62の参照範囲が既処方薬に限定され、類似判定が実施される。
判定レベル均一モードは、同一の処方に基づいて分包された一群の分包袋群の全部について鑑査用データベース62の参照範囲を同一範囲として類似判定を実施する動作モードである。すなわち、判定レベル均一モードを選択すると、分包袋群をなす全ての分包袋について、上述した(1-1)~(1-6)に係る動作モードから選択した任意の動作モードによって類似判定がなされる。
判定レベル重み付けモードは、類似判定における鑑査用データベース62の参照範囲を分包袋群の一部をなす分包袋についての鑑査時と他の分包袋についての鑑査時とで相違させる動作モードである。判定レベル重み付けモードには、鑑査用データベース62の参照範囲を拡大し、類似判定の判定レベルを他よりも高くする分包袋の選定方法に応じて、(2-2a)手動準備包重み付けモード、(2-2b)要注意薬包重み付けモード、(2-2c)オア条件重み付けモード、及び(2-2d)アンド条件重み付けモードの4つの動作モードのうちいずれかを選択して実施できる。すなわち、本実施形態においては、判定レベル重み付けモードの下位概念として、類似判定の判定レベルを高める分包袋に応じて手動準備包重み付けモード、及び要注意薬包重み付けモードの2つの動作モードを選択可能とされている。以下、判定レベル重み付けモードを構成する各動作モードについて説明する。
手動準備包重み付けモードは、判定レベル重み付けモードが選択された場合おいて、手動により手動薬剤供給部138に準備された薬剤(手動準備薬)を包装した分包袋(以下、「手動準備薬含有包」とも称す)が存在する場合に、この手動準備薬含有包についての判定レベルを、他の分包袋についての判定レベルよりも高く設定して類似判定を実施する動作モードである。具体的には、図6(a)において網掛けが施されていない分包袋のように手動準備薬が分包されたものについての類似判断に際して参照される鑑査用データベース62の参照範囲を、網掛けが施された手動準備薬を含まない分包袋の類似判定時における参照レベルよりも広くなるようにして類似判定を実行する。
要注意薬包重み付けモードは、鑑査用データベース62に登録されている薬剤のうち任意の薬剤を要注意薬剤(要管理薬剤)として予め選定しておくことにより実施可能な動作モードである。要注意薬剤は、鑑査用データベース62の構築時に予め選定しておくようにしても、ユーザーにより選定するようにしてもよい。要注意薬包重み付けモードを選定することにより、要注意薬として選定された薬剤を包装した分包袋(以下、「要注意薬含有包」とも称す)についての類似判定を、他の分包袋についての類似判定よりも重み付けして実施することができる。具体的には、図6(b)において網掛けが施された要注意薬を含まない分包袋について鑑査する際の鑑査用データベース62の参照範囲が、同図において網掛けが施された要注意薬を含む分包袋について鑑査する場合の参照範囲よりも広くなるようにして類似判定を行う。
オア条件重み付けモードは、手動準備薬含有包及び要注意薬含有包の双方についての類似判定の判定レベルを、他の分包袋についての判定レベルよりも高く設定して実施する動作モードである。すなわち、オア条件重み付けモードは、手動準備薬含有包あるいは要注意薬含有包について鑑査する際に、他の分包袋を鑑査する場合よりも判定レベルを高く設定する動作モードであり、上述した(2-2a)手動準備包重み付けモード及び(2-2b)要注意薬包重み付けモードの双方を一度に実施するモードとも言える。
アンド条件重み付けモードは、手動準備薬含有包であり、かつ要注意薬含有包でもある分包袋についての類似判定の判定レベルを、他の分包袋についての判定レベルよりも高く設定して実施する動作モードである。すなわち、アンド条件重み付けモードは、手動準備薬及び要注意薬の双方を含んでいる分包袋について鑑査する際に、他の分包袋を鑑査する場合よりも判定レベルを高く設定する動作モードである。
薬剤鑑査装置10は、分包袋を帯状に連続させた分包袋連続体の形態で供給することにより、鑑査部30に順次分包袋を到達させ、鑑査することができる。ここで、分包袋連続体をなす分包袋が、分包袋連続体の長手方向に同じ長さであれば、鑑査部30において各分包袋の鑑査が終了する度に所定の長さ分だけ分包袋連続体を繰り送れば良い。しなしながら、分包袋連続体をなす各分包袋の長さが均一でない場合に、鑑査終了毎に繰り送る分包袋連続体の長さが均一であると、鑑査対象である分包袋が鑑査部30に対して位置ズレを起こし、正確に鑑査できない可能性が高まる。
ここで、薬剤鑑査装置10においては、図10(a)等に示すように、所定方向に長い形状を有し、長手方向中間部を境として色彩が相違する薬剤(以下、「長形薬剤」とも称す)についての鑑査精度を向上させるべく、二色判定処理を実行可能とされている。本実施形態において二色判定処理の実施対象となる薬剤の具体例としては、カプセル剤、あるいはカプセルの形状・サイズを模した錠剤であるカプレット剤と称される薬剤が該当する。以下、二色判定処理の概要について簡単に説明し、その後実施方法について当該処理の主要部分を中心に説明する。
ここで、上述した薬剤鑑査装置10においては、鑑査対象である分包袋1包分の表面積Spに対し、この分包袋に含まれている薬剤の表面積Smの合計が大きい場合、すなわち両面積の比Sm/Spが1に近い場合が想定される。このように1包の分包袋に対して過剰に薬剤が分包されている場合には、分包袋に振動等を加えたとしても薬剤が分散せず、鑑査の際に薬剤が分包袋内で起立した状態のままになってしまう現象や、画像処理等により隣接する薬剤同士の境界を正確に把握できない現象が想定される。このような現象が生じた場合、薬剤の表面形状や大きさ、色彩等の画像情報を薬剤毎に登録したマスターデータベースと、撮影装置40により鑑査対象の分包袋を撮影した画像とを照合することにより、処方データ通りに分包袋内に薬剤が分包されているかについての鑑査をしようとしても十分な精度が得られない可能性がある。そのため、このような場合には、薬剤が過剰に分包されていることを理由として十分な鑑査精度が得られない可能性があることを使用者に示唆できる構成であることが望ましい。
同様の課題を解決するための方策として、上述したように袋面積Spや理論表面積Stを基準とする以外に、例えば分包袋及びこれに収容される薬剤の体積を基準とする等、他の方策を採用することも可能である。具体的には、分包袋内に十分な鑑査精度が得られないおそれがある程度まで薬剤が過剰に収容されていることを体積基準で判定する場合には、鑑査対象である分包袋に分包可能な最大数量(理論最大数量Nt)を各薬剤毎に把握し、マスターデータベース等に登録しておく。理論最大数量Ntは、分包袋1包分の容積Vpを薬剤1つ分の体積Vmで除した数量(Nt=Vp/Vm)とする等の理論的方法、あるいは実験的方法等により、各薬剤毎に導出しておく。
ここで、上述した薬剤鑑査装置10においては、撮影装置40により鑑査対象の分包袋を撮影した画像に基づいて薬剤が処方通りに分包されているかを鑑査するものである。そのため、分包袋を鑑査部30に搬送する際に、鑑査部30に対する分包袋の位置決め精度が低いと、鑑査精度も低くなってしまうおそれがある。そこで、ミシン目等の境界を介して多数の分包袋を一連とした分包袋連続体の状態で薬剤鑑査装置10に供給する構成である場合には、以下のようにしてかかる問題の発生を抑制することができる。
ここで、薬剤鑑査装置10において処方通りに薬剤が分包されているかを鑑査する際に、薬剤の表面形状や大きさ、色彩等の画像情報を薬剤毎に登録したマスターデータベースを参照する構成とした場合、マスターデータベースに登録されていない新規の採用薬品が分包されていると正確に鑑査を行うことができない。そのため、新規の採用薬品が用いられる場合には、その薬剤についての画像や情報を予めマスターデータベースに登録しておく必要がある。
上述した薬剤鑑査装置10による鑑査においては、マスターデータベースに登録されている薬剤の外観形状を示す画像データを用いて照合がなされる。そのため、マスターデータベースに薬剤の画像データを登録するためには、薬剤の輪郭線を略正確に把握し、切り出す等の画像処理が必要となる。薬剤の輪郭線を導出するための手段として以下のようなものがある。
