Description

本発明は、医療機関における使用済み医療器材の自動洗浄を始めとして、飲食品、医薬品、電子機器、その他の各種分野における材料、部品、製品、容器、取扱い器材等の自動洗浄を行う際に用いる洗浄評価用インジケーターに関する。 The present invention is used for automatic cleaning of materials, parts, products, containers, handling equipment, etc. in food and drink, pharmaceuticals, electronic devices, and other various fields, including automatic cleaning of used medical equipment in medical institutions. It relates to an indicator for cleaning evaluation.

近年、医療機関におけるステンレス鋼製の鉗子やメス等の繰り返し使用する医療器材の洗浄には、噴射式や超音波式等の洗浄装置による自動洗浄が一般化している。この自動洗浄では、作業者が使用済み医療器材を所要部位にセットすれば、後は洗浄装置が予め設定した各種パラメーターを含むプログラムに従って洗浄を行い、洗浄後の医療器材が自動的に該洗浄装置から排出される。 In recent years, automatic cleaning using a cleaning apparatus such as an injection type or an ultrasonic type has become common for cleaning medical devices such as stainless steel forceps and scalpels that are repeatedly used in medical institutions. In this automatic cleaning, if an operator sets a used medical device at a required site, the cleaning device performs cleaning according to a program including various parameters set in advance, and the cleaned medical device is automatically set in the cleaning device. Discharged from.

しかるに、上記パラメーターは例えば給水量、給水温度、洗浄剤量、洗浄剤種別、チャンバー内温度、各工程処理時間、ポンプによる洗浄水吐出圧力、超音波出力、その他の極めて多岐にわたり、これらパラメーターの一つにでも異常を生じれば所期する洗浄機能が発揮されず、洗浄不良に繋がる懸念があるが、この種の洗浄装置の制御機構部は言わばブラックボックスであるため、パラメーター異常の有無を外部から確認することは極めて困難である。 However, for example, the above parameters are very wide, such as the amount of water supply, water supply temperature, amount of cleaning agent, type of cleaning agent, chamber temperature, process time, cleaning water discharge pressure by pump, ultrasonic output, etc. If any abnormality occurs, the expected cleaning function may not be achieved and there may be a risk of cleaning failure, but the control mechanism of this type of cleaning device is a black box. It is extremely difficult to confirm from

そこで、洗浄装置による洗浄が正常に行われているか否かを判定するために、洗浄評価用インジケーターが使用されている。この洗浄評価用インジケーターは、合成樹脂シートや金属薄板からなる基材に洗浄評価指標物として血液由来の蛋白質等よりなる疑似汚染物を塗着した判定片を専用のホルダーに納め、このホルダーを使用済み医療器具と一緒に洗浄装置の洗浄槽にセットして洗浄を行い、洗浄後の判定片をホルダーから取り出して疑似汚染物の有無を調べることにより、洗浄の適否を判定するものである。しかして、一般的には、判定片に塗着する疑似汚染物は色素で着色され、洗浄後の着色の有無あるいは着色程度を目視判定するようになっている。 Therefore, a cleaning evaluation indicator is used to determine whether or not the cleaning by the cleaning device is normally performed. This indicator for cleaning evaluation is used by placing a judgment piece in which a pseudo-contamination made of blood-derived protein or the like is applied as a cleaning evaluation index material on a substrate made of a synthetic resin sheet or metal thin plate in a dedicated holder. Washing is performed by setting it in a washing tank of a washing apparatus together with a used medical instrument, and the suitability of washing is judged by taking out the judgment piece after washing from the holder and checking for the presence of pseudo-contaminants. Therefore, generally, the pseudo-contaminant to be applied to the judgment piece is colored with a pigment, and the presence or degree of coloring after washing is visually judged.

また、上記ホルダーとしては、洗濯挟み式に開閉する一対の多孔板間で判定片を挟持するもの（特許文献１）、Ｌ字形金属板の長尺側に判定片を重ねて両端部を板バネで挟着するもの、開口部付きの偏平なプラスチックケース内に判定片を納めるもの等、種々の形態が知られている。
特表２００６−５２５０５９号公報 In addition, as the holder, a judgment piece is sandwiched between a pair of perforated plates that open and close in a laundry pinch manner (Patent Document 1), the judgment pieces are stacked on the long side of an L-shaped metal plate, and both ends are leaf springs. Various forms are known, such as a case where the judgment piece is placed in a flat plastic case with an opening, and the like.

図２に示すように、ケーシング１の内部空間１０には、前板部１１側に配置する長い板片３０ａと、上板部１５の内面に接する基板部３０ｂと、後板部１２の内面に接する短い板片３０ｃとで略コ字形をなすステンレス鋼製の板ばね３０が装填されており、その長い板片３０ａをケーシング１の前板部１５に押接させる方向にばね蓄力を有している。また、該ケーシング１の前板部１１の中央側にはねじ孔１１ａが設けてあり、このねじ孔１１ａに外側から螺挿した調整ねじ３１の内端が板ばね３０の長い板片３０ａに押接しており、該調整ねじ３１の螺挿深度によってケーシング１の前後方向に傾動変位し、例えば図２の実線で示す位置から調整ねじ３１を緩めることにより、板片３０ａが図示仮想線の如く前板部１５に近接する傾斜姿勢に変化する。 As shown in FIG. 2, in the internal space 10 of the casing 1, a long plate piece 30 a disposed on the front plate portion 11 side, a substrate portion 30 b in contact with the inner surface of the upper plate portion 15, and an inner surface of the rear plate portion 12. A plate spring 30 made of stainless steel having a substantially U-shape with a short plate piece 30c in contact therewith is loaded, and has a spring accumulation force in a direction in which the long plate piece 30a is pressed against the front plate portion 15 of the casing 1. ing. Further, a screw hole 11 a is provided at the center side of the front plate portion 11 of the casing 1, and the inner end of the adjustment screw 31 screwed into the screw hole 11 a from the outside is pressed against the long plate piece 30 a of the leaf spring 30. The plate 30a is moved forward as shown in the imaginary line by loosening the adjustment screw 31 from the position indicated by the solid line in FIG. It changes to an inclined posture close to the plate portion 15.

しかして、板ばね３０の長い板片３０ａは、先端がケーシング１の三角開口部２ｂ，２ｂに臨む長さに設定されており、その傾動変位によって洗浄液導入口２側の流路面積を拡縮する液流通調整手段３として機能している。また、図１及び図５に示すように、ケーシング１の側板部１４の外面下縁部には目盛り１６が刻設されており、板片３０ａの傾動変位による洗浄液導入口２側の流路面積の拡縮度合を、三角開口部２ｂから視認される当該板片３０ａの先端部の位置にて読み取れるようになっている。 Thus, the long plate piece 30a of the leaf spring 30 is set to a length at which the tip thereof faces the triangular openings 2b and 2b of the casing 1, and the flow passage area on the cleaning liquid inlet 2 side is enlarged or reduced by the tilt displacement. It functions as the liquid flow adjusting means 3. Further, as shown in FIGS. 1 and 5, a scale 16 is formed on the lower edge of the outer surface of the side plate portion 14 of the casing 1, and the flow path area on the cleaning liquid inlet 2 side due to the tilt displacement of the plate piece 30a. The degree of expansion / contraction can be read at the position of the tip of the plate piece 30a visually recognized from the triangular opening 2b.

一方、シートホルダーＨに付設された掛止枠７は、一本のステンレス鋼線から折曲形成されており、図３〜図５に示すように、ケーシング１の背面側に正面視略Ｕ字形に配置した下垂部７０と、そのＵ字形の両側上端で２巻回した蔓巻き部７１，７１と、各蔓巻き部７１から前方へ逆Ｌ字形に突出した上辺部７２とで側面視７の字形のタコばね構造をなしている。そして、この掛止枠７の両端部７ａ，７ａは、上辺部７２，７２の下端から更に更に内向きに曲折し、ケーシング１の両側板部１４，１４の上縁に設けた取付孔１４ａより当該ケーシング１内に突入しており、もって当該掛止枠７をケーシング１に係着すると共に、該ケーシング１の上板部１５との間で板ばね３０の基板部３０ｂを挟み付けることにより、該板ばね３０の抜け止め機能をも担っている。なお、この掛止枠７のケーシング１への係着状態において、下垂部７０は当該ケーシング１の背面に当接又は近接して配置しており、下垂部７０を強制的に後方へ引っ張って上辺部７２，７２との開きを大きくした場合、前記タコばね構造によって該開きを小さくする方向のばね蓄力を生じる。 On the other hand, the retaining frame 7 attached to the seat holder H is bent from a single stainless steel wire, and is substantially U-shaped in front view on the back side of the casing 1 as shown in FIGS. 7 in a side view, with a hanging part 70 arranged at the top, a vine part 71, 71 wound twice at the upper ends of both sides of the U-shape, and an upper side part 72 protruding in an inverted L shape forward from each vine part 71 It has a letter-shaped octopus spring structure. Then, both end portions 7a, 7a of the retaining frame 7 are bent further inward from the lower ends of the upper side portions 72, 72, and from the mounting holes 14a provided at the upper edges of the side plate portions 14, 14 of the casing 1. By rushing into the casing 1, the latch frame 7 is engaged with the casing 1, and the base plate portion 30 b of the leaf spring 30 is sandwiched between the upper plate portion 15 of the casing 1, It also has a function of preventing the leaf spring 30 from coming off. In this state, the hanging part 70 is disposed in contact with or close to the back surface of the casing 1, and the upper side is forcibly pulled backward. When the opening between the portions 72 and 72 is increased, a spring accumulating force in a direction to reduce the opening is generated by the octopus spring structure.

判定シートＳをシートホルダーＨに装着するには、図１で示すように、一方の手でシートホルダーＨをケーシング１の前板部１１が上向きになるように保持すると共に、他方の手で判定シートＳを疑似汚染物塗膜９側が上向きで先端側になるように保持し、この判定シートＳをシートホルダーＨのシート挿入口４に合わせて挿入する。そして、図２に示すように、該判定シートＳの先端がケーシング１の内端（上板部１５の内面側）まで達した状態で、同図の仮想線の如くシート挿入口４から外側に出ている当該判定シートＳの外側突出部Ｓａを掴んで持ち上げ、同図実線の如くシート挿入口４で曲げて強制的に該外側突出部Ｓａの両側部を爪片５，５に乗り上げさせれば、該判定シートＳは曲がりを戻そうとする弾発力によってケーシング１から抜出不能に係止される。 To attach the determination sheet S to the sheet holder H, as shown in FIG. 1, hold the sheet holder H with one hand so that the front plate portion 11 of the casing 1 faces upward, and determine with the other hand. The sheet S is held so that the pseudo-contamination coating film 9 side is facing upward and the leading end side, and the determination sheet S is inserted in accordance with the sheet insertion port 4 of the sheet holder H. Then, as shown in FIG. 2, with the leading edge of the judgment sheet S reaching the inner end of the casing 1 (inner surface side of the upper plate portion 15), as shown by the phantom line in FIG. The outer protruding portion Sa of the judgment sheet S that has come out can be grabbed and lifted and bent at the sheet insertion opening 4 as shown by the solid line in the figure to force both sides of the outer protruding portion Sa to ride on the claw pieces 5 and 5. In this case, the determination sheet S is locked so that it cannot be removed from the casing 1 by the elastic force to return the bend.

かくして、シートホルダーＨに判定シートＳを装着したインジケーターは、例えば医療器材用洗浄装置の洗浄物収容部に配置させ、使用済み医療器材の如き洗浄物と共に所定の洗浄を施す。このとき、適用する洗浄装置が噴射式の場合、図６で示すように、シートホルダーＨは、使用済み医療器材Ｔ…を納める洗浄バスケットＢの立ち上げ縁部Ｂａの外側に、掛止枠７を利用してケーシング１の洗浄液導入口２側が下向きになる形で掛止させ、旋回する噴射アームＡのノズルＮが真下を通過する位置に設定し、もってノズルＮから噴射される洗浄液Ｌが洗浄液導入口２からケーシング１の内部空間１０に入り込み易くする。また、洗浄装置が超音波式のように浸漬型の洗浄槽を持つ場合は、該シートホルダーＨを医療器材Ｔと一緒に洗浄槽に入れて洗浄液に浸漬させればよい。 Thus, the indicator having the determination sheet S mounted on the sheet holder H is disposed in, for example, the cleaning object storage unit of the cleaning device for medical equipment, and performs predetermined cleaning together with the cleaning object such as used medical equipment. At this time, when the cleaning device to be applied is an injection type, as shown in FIG. 6, the seat holder H is placed on the outer side of the rising edge portion Ba of the cleaning basket B in which the used medical equipment T. , The cleaning liquid inlet 2 side of the casing 1 is hooked in a downward direction, and the nozzle N of the swiveling injection arm A is set to a position where it passes directly below, so that the cleaning liquid L sprayed from the nozzle N is the cleaning liquid. It makes it easy to enter the internal space 10 of the casing 1 from the inlet 2. Further, when the cleaning apparatus has an immersion type cleaning tank such as an ultrasonic type, the sheet holder H may be placed in the cleaning tank together with the medical device T and immersed in the cleaning liquid.

そして、洗浄終了後、シートホルダーＨから判定シートＳを取り出し、疑似汚染物塗膜９の残留状況を調べて洗浄の適否を判定する。この判定シートＳの取り出しにおいては、爪片５，５に乗り上げさせていた外側突出部Ｓａを強制的に両爪片５，５の下側へ押し下げて係止解除し、もって全体が平坦に戻った当該判定シートＳをケーシング１から引き出せばよい。 And after completion | finish of washing | cleaning, the determination sheet | seat S is taken out from the sheet | seat holder H, the residual condition of the pseudo-contamination coating film 9 is investigated, and the suitability of washing | cleaning is determined. When the determination sheet S is taken out, the outer protruding portion Sa that has been ridden on the claw pieces 5 and 5 is forcibly pushed down to the lower side of the claw pieces 5 and 5 to release the lock, and the whole returns to a flat state. The determination sheet S may be pulled out from the casing 1.

この判定シートＳによって洗浄装置のパラメーター異常を捉えるには、洗浄装置の各種パラメーターが全て正常である場合と、何らかのパラメーター異常による洗浄不良を生じた場合とで、洗浄後の該判定シートＳにおける疑似汚染物塗膜９の残留状況に明瞭な違いが現われることが必要である。しかるに、このインジケーターでは、液流通調整手段３つまり調整ねじ３１による板ばね３０の板片３０ａの傾動変位により、洗浄液導入口２側の流路面積を拡縮してケーシング１内部の液流通度合を調整でき、この液流通度合によって判定シートＳの疑似汚染物塗膜９に対する洗浄負荷が変化するから、予め洗浄装置の各パラメーターが全て正常な状態での洗浄終了時ぎりぎりに疑似汚染物塗膜９の全てが除去される臨界状態になるように、調整ねじ３１で板ばね３０の板片３０ａの位置を設定しておけば、何らかのパラメーター異常が発生した場合に、その異常を疑似汚染物塗膜９の残留として容易に的確に捉えることが可能となる。 In order to catch the parameter abnormality of the cleaning device by using this determination sheet S, the pseudo in the determination sheet S after the cleaning is performed when the various parameters of the cleaning device are all normal and when the cleaning failure occurs due to some parameter abnormality. It is necessary that a clear difference appears in the residual state of the contaminant coating 9. However, this indicator adjusts the degree of liquid flow in the casing 1 by expanding and contracting the flow area on the side of the cleaning liquid inlet 2 by the tilt displacement of the plate piece 30a of the leaf spring 30 by the liquid flow adjusting means 3, that is, the adjusting screw 31. Since the cleaning load on the pseudo-contamination coating film 9 of the determination sheet S changes depending on the degree of liquid flow, the pseudo-contamination coating film 9 can be applied immediately before the end of cleaning with all parameters of the cleaning device in advance. If the position of the plate piece 30a of the leaf spring 30 is set with the adjusting screw 31 so as to be in a critical state in which everything is removed, if any parameter abnormality occurs, the abnormality is detected as the pseudo-contamination coating film 9. It can be easily and accurately grasped as the residual of the above.

しかも、このインジケーターでは、上述のように液流通調整手段３によって判定シートＳの疑似汚染物塗膜９に対する洗浄負荷を自在に調整できるから、洗浄装置の洗浄方式や機種の違い、洗浄対象の医療器材の種類と量、汚れ度合等による洗浄条件の違いがあっても、支障なく前記の臨界状態に容易に設定できる。 In addition, in this indicator, the washing load on the pseudo-contamination coating film 9 of the determination sheet S can be freely adjusted by the liquid flow adjusting means 3 as described above. Even if there is a difference in cleaning conditions depending on the type and amount of equipment, the degree of contamination, etc., the above critical state can be easily set.

また、このインジケーターにおいては、ケーシング１の後部側に設けた小開口部６ａ，６ａにより、洗浄中の該ケーシング１内の空気及び液を排出できるから、空気による判定シートＳ表面の濡れ不良や液滞留による判定結果への悪影響を排除できると共に、ケーシング１の洗浄液導入口２が多数のパンチング孔２ａ…からなることにより、該ケーシング１内への洗浄液流入が均等化し、液流の偏在による判定結果への悪影響が回避される。 Further, in this indicator, since the air and the liquid in the casing 1 being cleaned can be discharged by the small openings 6a and 6a provided on the rear side of the casing 1, the surface of the determination sheet S due to the air is poorly wet or liquid The adverse effect on the determination result due to the retention can be eliminated, and the cleaning liquid inlet 2 of the casing 1 is made up of a number of punching holes 2a, so that the flow of the cleaning liquid into the casing 1 is equalized, and the determination result due to the uneven distribution of the liquid flow The adverse effect on is avoided.

更に、このシートホルダーＨでは、図６で示すように噴射式の洗浄装置の洗浄バスケットＢの側壁Ｂａに掛止枠７を利用して掛止させる際、当該側壁Ｂａの頂部が縁材Ｅや折り返し等によって種々異なる出っ張り形状であっても、その頂部に対して掛止枠７の側面視７の字形における拡がった上部７ｂで支障なく跨嵌できると共に、該掛止枠７がタコばね構造を有するから、その下垂部７０とケーシング１との間で側壁Ｂａを挟み付けた形で、ばね蓄力によって安定した係着固定状態が得られる。 Further, in the seat holder H, when the hooks 7 are used to hook the side walls Ba of the cleaning basket B of the spray type cleaning device as shown in FIG. Even if the protruding shape is different depending on the folded-back shape or the like, the upper portion 7b of the hanging frame 7 in the shape of a side view 7 can be fitted over the top without any trouble, and the hanging frame 7 has an octopus spring structure. Therefore, a stable engagement and fixing state can be obtained by the spring accumulation force with the side wall Ba sandwiched between the hanging portion 70 and the casing 1.

なお、本発明の洗浄評価用インジケーターは、上述のような医療器材用洗浄装置による医療器材の自動洗浄における洗浄評価に特に好適であるが、飲食品、医薬品、電子機器、その他の各種分野における材料、部品、製品、容器、取扱い器材等の洗浄装置による自動洗浄を行う場合にも同様に適用できる。しかして、適用する洗浄装置の洗浄方式としては、籠形の洗浄物収容部に対して洗浄水を噴射する噴射式と、水槽形の洗浄物収容部内の洗浄水に超音波振動を付与する超音波式とが特に推奨される。 The cleaning evaluation indicator of the present invention is particularly suitable for cleaning evaluation in automatic cleaning of medical equipment by the medical equipment cleaning apparatus as described above, but is used in food and drink, pharmaceuticals, electronic equipment, and other various fields. The present invention can also be applied to the case where automatic cleaning is performed by a cleaning device for parts, products, containers, handling equipment, and the like. Therefore, as a cleaning method of the cleaning device to be applied, a jet type that jets cleaning water to the bowl-shaped cleaning object storage unit, and an ultrasonic wave that applies ultrasonic vibration to the cleaning water in the tank-shaped cleaning object storage unit. The sonic method is particularly recommended.

本発明では、ケーシング１内の液流通調整手段３として、板ばね３０及び調整ねじ３１を用いる代わりに、傾動板として単板の一端側をケーシング１に枢着し、該端板に螺挿したねじ材で傾動変位させる等、様々な方式を採用できる。ただし、実施形態のように板ばね３０及び調整ねじ３１を用いる方式では、ケーシング１内の液流通度合を容易に且つ確実に設定できる上、流路面積を拡大する方向の傾動変位にばね蓄力を利用できるから、機構的及び構造的により簡素になって故障を生じにくく、作動の信頼性に優れると共に、シートホルダーＨの組立製作コストも低減するという利点がある。 In the present invention, instead of using the leaf spring 30 and the adjusting screw 31 as the liquid flow adjusting means 3 in the casing 1, one end of a single plate as a tilting plate is pivotally attached to the casing 1 and screwed into the end plate. Various methods such as tilting displacement with screw material can be adopted. However, in the method using the leaf spring 30 and the adjusting screw 31 as in the embodiment, the liquid flow degree in the casing 1 can be set easily and reliably, and the spring accumulation force is applied to the tilt displacement in the direction of expanding the flow path area. Therefore, there is an advantage that it is simpler mechanically and structurally, is less likely to cause a failure, is excellent in operation reliability, and reduces the cost of assembling and manufacturing the seat holder H.

更に、シートホルダーＨにおけるシート係止手段としては、例示した爪片５，５に限らず、例えば、ばね等を利用して判定シートＳの端を挟み付けるクリップ機構等、種々の方式を採用できる。しかるに、実施形態のような爪片５，５によれば、シートホルダーＨに対する判定シートＳの着脱操作がより簡単になると共に、該爪片５，５をケーシング１に容易に一体形成できるという利点もある。 Further, the sheet locking means in the sheet holder H is not limited to the illustrated claw pieces 5 and 5, and various methods such as a clip mechanism for sandwiching the end of the determination sheet S using a spring or the like can be employed. . However, according to the claw pieces 5 and 5 as in the embodiment, the attachment / detachment operation of the determination sheet S with respect to the sheet holder H becomes easier, and the claw pieces 5 and 5 can be easily formed integrally with the casing 1. There is also.

一方、判定シートＳの半硬質シート基材８としては、可撓性で且つ腰の強い耐水性材質のものがよく、例えば合成紙、合成樹脂シート、合成樹脂ラミネート紙等が好適である。また、洗浄評価指標物とする疑似汚染物塗膜９の疑似汚染物としては、洗浄評価を行うべき洗浄物の汚れ物質に対応した適当な成分を選択して使用すればよいが、医療器材の洗浄評価では血清グロブリン、オポグロブリン、ラクトグロブリン、フィブリン、ヘモグロビン、牛血清アルブミン、細胞外マトリックスの如き動物性蛋白質の他、トウモロコシ、小麦、大豆、稲等に含まれる種子蛋白のプロラミン及びグルテリンの如き植物性蛋白質が挙げられる。しかして、塗膜９には疑似汚染物としての脂質や炭水化物、着色剤、バインダ成分、増粘剤、ｐＨ調整剤等、種々の成分を適宜含有していてもよい。 On the other hand, the semi-rigid sheet substrate 8 of the determination sheet S is preferably made of a water-resistant material that is flexible and strong. For example, synthetic paper, synthetic resin sheet, synthetic resin laminated paper, and the like are suitable. Moreover, as the pseudo-contamination of the pseudo-contamination coating film 9 used as the cleaning evaluation index material, an appropriate component corresponding to the dirt substance of the cleaning object to be subjected to cleaning evaluation may be selected and used. In the washing evaluation, animal proteins such as serum globulin, opoglobulin, lactoglobulin, fibrin, hemoglobin, bovine serum albumin, and extracellular matrix, as well as seed proteins such as prolamin and glutelin contained in corn, wheat, soybean, rice, etc. Plant protein is mentioned. Thus, the coating film 9 may appropriately contain various components such as lipids and carbohydrates as a pseudo-contaminant, a colorant, a binder component, a thickener, and a pH adjuster.

その他、本発明の洗浄評価用インジケーターでは、シートホルダーＨにおけるケーシング１の外形、洗浄水導入口２の構成、板ばね３０の構造、ケーシング１の後部側に設ける小開口部の形状、掛止枠７の構造、判定シートＳにおける半硬質シート基材８の形状、疑似汚染物塗膜９の塗着形態等、細部構成については実施形態以外に種々設計変更可能である。 In addition, in the indicator for cleaning evaluation of the present invention, the outer shape of the casing 1 in the seat holder H, the configuration of the cleaning water inlet 2, the structure of the leaf spring 30, the shape of the small opening provided on the rear side of the casing 1, the retaining frame In addition to the embodiment, various design changes can be made to the detailed configuration such as the structure of 7, the shape of the semi-rigid sheet substrate 8 in the determination sheet S, and the form of application of the pseudo-contamination coating film 9.
