Description

【０００１】
【発明の属する技術分野】
本発明は超音波探触子用滅菌・消毒保護袋及びその製造方法に関し、特にケーブル及びコネクタ付きの超音波探触子を薬液中で滅菌・消毒する際に、コネクタ部分を防水保護するための超音波探触子用滅菌・消毒保護袋に属する。
【０００２】
【従来の技術】
超音波を人体に入射してその反射波を利用し、人体の各部を診断する超音波診断装置は、現在医療において必要不可欠である。その中の１つである、超音波探触子の一例を図６に示す。
この超音波探触子５００は、生体と接触してこの生体に超音波を入射し、その反射波を受波する探触子５１０と、超音波診断装置本体と電気的に接続してこの超音波診断装置本体との間で信号の授受を行うコネクタ５３０と、探触子５１０・コネクタ５３０間を接続するケーブル５２０と、を有する構造となっている。
【０００３】
このような超音波探触子５００は、術中時や穿刺術時に滅菌、消毒が行われるが、近年、薬液による高度の消毒、滅菌の要望が高まり、超音波探触子５００全体を丸ごと薬液中に浸す必要性に迫られている。しかしながら、そのコネクタ５３０部分は、超音波診断装置本体との間で電気的な接続を行うため、防水構造とはなっていない。
【０００４】
そこで、この超音波探触子５００全体を丸ごと薬液中に浸して滅菌、消毒する際に、そのコネクタ５３０部分を防水保護するために、図７（ａ），（ｂ）に示すように、コネクタ５３０部分に、市販のポリエチレン袋６００をかぶせてその開口部分からケーブルを引き出し、この開口部分寄りの部分をしぼってその上からケーブル５２０ごと、ひも７００で縛り付ける、という方法が一般的に採用されていた。すなわち、従来の超音波探触子用滅菌・消毒保護袋の一般的な例としては、市販のポリエチレン袋６００を用いていた。
【０００５】
なお、超音波探触子５００に対し滅菌、消毒が必要な部分は、探触子５１０と、これにつながるケーブル５２０の限定された部分であり、コネクタ５３０はその必要がないが、滅菌、消毒の自動化が進み、ケーブル５２０及びコネクタ５３０を含めて薬液に浸すのが簡便であるので、コネクタ部分に袋をかぶせる、という方法が採用されている。
【０００６】
【発明が解決しようとする課題】
上述した従来の超音波探触子用滅菌・消毒保護袋は、市販のポリエチレン袋６００を用いて、超音波探触子５００のコネクタ５３０部分にかぶせ、このポリエチレン袋６００の開口部分からケーブル５２０を引き出してその開口部分寄りの部分をしぼり、その上からケーブル５２０ごと、ひも７００で縛り付ける構造となっている。しかし、ポリエチレン袋６００の、ひも７００で縛り付けた部分に多数のしわが発生し、このしわを通して薬液が内部に侵入するため、コネクタ５３０に対する十分な防水保護ができない、という問題点があった。
【０００７】
本発明の目的は、上記従来技術の問題点に鑑みて、超音波探触子を薬液中で滅菌、消毒する際に、ケーブル引出し部分から内部に薬液が侵入するのを防ぐことができて、コネクタを保護することができる超音波探触子用滅菌・消毒保護袋及びその製造方法を提供することにある。
【０００８】

【発明の実施の形態】
本発明の第１の超音波探触子用滅菌・消毒保護袋の一実施の形態は、コネクタ及びケーブル付きの超音波探触子を滅菌、消毒する際に上記コネクタを薬液に対し防水保護するための、合成樹脂シート製の超音波探触子用滅菌・消毒保護袋であって、
袋状を成すその内側に上記コネクタを収容しこれをカバーするコネクタ封入部と、
このコネクタ封入部の開口部分が、その縁を延長する方向に広げられ、かつこの縁の延長部分に対し予め定められた幅を有して上記コネクタ封入部から横方向に突出し、この突出した部分の上記縁の延長部分と相対向する辺の部分の重なり合う２枚のシート間が上記コネクタ封入部との付根部分から互いにつながり、上記横方向に突出した部分の先端は重なり合う２枚のシート間が開放されて、上記コネクタ封入部内のコネクタからのケーブルを上記コネクタ封入部から外部へと引き出し、かつその周囲を包む、ケーブル引出し部と、
上記コネクタ封入部の開口部分、及びその延長部分を封止する、開口シール部と、
上記ケーブル引出し部の、上記縁の延長部分と相対向する辺の部分につながって延び、上記ケーブル引出し部に包まれて上記開口シール部で封止されたケーブルに対し、その上から巻きつけられて互いに結ばれる、２枚のケーブル縛りひも部と、
を含んで構成され、上記ケーブル引出し部は、その開口部分の延長された縁に相対向する辺と上記開口シール部との幅が、その突出先端部分で、上記ケーブルを包み上記開口シール部で封止したときに、上記ケーブルの周囲に密着する程度の寸法となっている。
【００１７】
このような構成とすることにより、この超音波探触子用滅菌・消毒保護袋からケーブルを引き出す部分に、しわの出来るのを抑えることができて、超音波探触子全体を薬液に浸した状態でも、内部に薬液が入り込むのを防ぐことができ、防水構造になっていないコネクタを薬液から保護することができる。

なお、市販のファスナー付き合成樹脂シート製袋を使用しないで、１枚の合成樹脂シートから直接製造することもできる。この場合、開口部分のシールを両面接着テープで行うことにより、その部分の形成が容易となる。
【００２０】
また、本発明の第２の超音波探触子用滅菌・消毒保護袋の一実施の形態は、上記第１の超音波探触子用滅菌・消毒保護袋における、２枚のケーブル縛りひも部に代えて、ケーブル引出し部の、コネクタ封入部の開口部分が延長された部分の縁と相対向する辺の部分につながって帯状に延び、その片側の面に、両面接着テープが接着、配置されて、上記ケーブル引出し部に包まれ、かつ開口シール部で封入されたケーブルに対し、その上から巻きつけられて上記両面接着テープで固定される、ケーブル巻付け帯部、を含んで構成される。

この第２の超音波探触子用滅菌・消毒保護袋、及びその製造方法においても、前述と同様の作用効果が得られる。
【００２２】
【実施例】
次に本発明の実施例について図面を参照して説明する。
図１は本発明の第１の超音波探触子用滅菌・消毒保護袋の一実施例を示す斜視図、図２（ａ），（ｂ）はこの第１の超音波探触子用滅菌・消毒保護袋に、ケーブル及びコネクタ付きの超音波探触子のコネクタ部分を入れてその開口部分をシールする前の状態、及びシールし、かつそのケーブル縛りひも部でケーブル引出し部分を縛り付けた状態を示す斜視図である。
【００２３】
この実施例の第１の超音波探触子用滅菌・消毒保護袋は、１枚の合成樹脂シート、例えばポリエチレンシートで形成されて、溶着部１１１により袋状を成してその内側にコネクタ５３０を収容しこれをカバーするコネクタ封入部１１０と、このコネクタ封入部１１０へコネクタ５３０を出し入れする開口部１１２が、その縁を延長する方向に広げられ、かつこの縁の延長部分（１１２ｅ）に対し予め定められた幅（後述）を有してコネクタ封入部１１０から横方向に突出し、この突出した部分の上記縁の延長部分（１１２ｅ）と相対向する辺の部分の重なり合う２枚のシート間が溶着部１１１でコネクタ封入部１１０との付根部分から互いにつながり、横方向に突出した部分の先端は重なり合う２枚のシート間が開放されて、コネクタ封入部１１０内のコネクタ５３０から延びるケーブル５２０をこのコネクタ封入部１１０から外部へと引き出し、かつその周囲を包むケーブル引出し部１２０と、コネクタ封入部１１０の開口部１１２及びそのケーブル引出し部１２０への延長部分を封止する、ファスナー型の開口シール部１３０と、ケーブル引出し部１２０の、開口部１２０の縁の延長部分（１１２ｅ）と相対向する辺の部分につながってコネクタ封入部１１０に対し並行に延び、ケーブル引出し部１２０に包まれて開口シール部１３０で封止されたケーブル５２０をその上から縛りつける、２枚のケーブル縛りひも部１４０と、コネクタ封入部１１０の周囲の溶着部１１１にＶ字状に形成されたＶカット部１５０と、を含む構造となっている。
【００２４】
この実施例においては、図２（ａ）に示すように、超音波探触子５００のコネクタ５３０部分をコネクタ封入部１１０内に収容し、ケーブル５２０をケーブル引出し部１２０に押し込んで、図２（ｂ）に示すように、開口部１１２及びその延長部分（１１２ｅ）を開口シール部１３０で封止した後、ケーブル５２０を、ケーブル縛りひも部１４０によりケーブル引出し部１２０の上から縛りつける。
【００２５】
このケーブル引出し部１２０は、その開口部１１２の延長部分（１１２ｅ）の縁に相対向する辺と開口シール部１３０との幅が、突出した先端部分で、ケーブル５２０を包み開口シール部１３０で封止したときに、ケーブル５２０の周囲に密着する程度の寸法となっている。
【００２６】
従って、ケーブル５２０をケーブル引出し部１２０で包んで開口シール部１３０で封止した後、その上からケーブル縛りひも部１４０で縛りつけたときに、このケーブル引出し部１２０の部分にしわが発生するのを抑えることができ、薬液中に浸されたとしても、コネクタ封入部１１０内に薬液等が浸入するのを防ぐことができる。
【００２７】
なお、Ｖカット部１５０は、滅菌、消毒が終了した後、コネクタ５３０を急いで超音波診断装置に接続する必要性が生じた場合、付着する薬液等を拭い去った後、このＶカット部１５０でコネクタ封入部１１０を破り、コネクタ５３０をその外部に取り出して接続すればよい。
【００２８】
次に、この第１の超音波探触子用滅菌・消毒保護袋の製造方法について説明する。
前述の図１に示された第１の超音波探触子用滅菌・消毒保護袋は、その説明にもあるように、１枚の合成樹脂シート、例えばポリエチレンシートで形成、製造されている。
その製造方法は、まず、ポリエチレンシートを２つ折りにたたんで重ね合せ、コネクタ封入部１１０、ケーブル引出し部１２０、開口シール部１３０、及びケーブル縛りひも部１４０となる部分を残して切除し（シート切断・成形工程）、ケーブル引出し部１２０とケーブル縛りひも部１４０との境界部分、及びこれとつながり、コネクタ封入部１１０の周囲の、開口部１１２及びケーブル引出し口部分以外の部分を溶着（溶着部１１１）し（シート間溶着工程）、開口部１１２の部分（ケーブル引出し部１２０の部分も含む）にファスナー等の開口シール部１３０を形成する。また、必要に応じて、コネクタ封入部１１０の周囲の溶着部１１１の設定位置に、Ｖカット部１５０を形成し、図１に示された第１の超音波探触子用滅菌・消毒保護袋が完成する。
【００２９】
この実施例では、開口シール部１３０をファスナー型としているが、これに代えて、開口部１１２の部分の、重なり合う２枚のシートのうちの何れか一方に、両面接着テープを、その非接着性テープが付着した状態で接着しておき、使用時に、コネクタ及びケーブルを収容した後、この非接着性テープをはがし、開口部１１２の、２枚のシート間を接着するようにすることもできる。
【００３０】
図３（ａ），（ｂ）は第１の超音波探触子用滅菌・消毒保護袋の製造方法の他の例を、製造工程順に示したその側面図である。
この製造方法は、まず、市販のファスナー付き合成樹脂シート製袋（例えばポリエチレン袋、以下ポリエチレン袋という）を、コネクタ封入部（１１０）、ケーブル引出し部（１２０）、ケーブル縛りひも部（１４０）となる部分を残して切除し、このとき、ケーブル引出し部の突出先端部分となる部分を切除すると共に、ケーブル縛りひも部（１４０）が２枚に分離するように、その外側の部分も切除する（ファスナー付ポリエチレン袋の切断工程）。
【００３１】
続いて、コネクタ封入部（１１０）となる部分の、ケーブル縛りひも部（１４０）側の辺部分、及びケーブル縛りひも部（１４０）・ケーブル引出し部（１２０）間の境界部分の、重なり合う２枚のシート間を、連続して溶着し（シート間溶着工程）、この第１の超音波探触子用滅菌・消毒保護袋が完成する。
【００３２】
すなわち、市販のファスナー付ポリエチレン袋から、極めて容易、かつ安価に、目的とする袋を造り出すことができる。
なお、これらの製造方法において、不要部分の切除する工程、シートの溶着工程等は、その順序を、製造しやすいように入れ換えることができる。
【００３３】
図４は本発明の第２の超音波探触子用滅菌・消毒保護袋の一実施例を示す斜視図、図５（ａ），（ｂ）はこの第２の超音波探触子用滅菌・消毒保護袋に、ケーブル及びコネクタ付きの超音波探触子のコネクタ部分を入れてその開口部分をシールする前の状態、及びシールし、かつそのケーブル巻付け帯部でケーブル引出し部分を巻き付けた状態を示す斜視図である。
【００３４】
この実施例の第２の超音波探触子用滅菌・消毒保護袋は、前述の第１の超音波探触子用滅菌・消毒保護袋における、２枚のケーブル縛りひも部１４０の部分を、その重なり合う２枚のシート間で溶着し（溶着部１１１ａ）、その片側の面に、両面接着テープ１４６を、その非接着性テープ１４７が付着したままの状態で接着、配置して、この部分をケーブル巻付け帯部１４５とした構造を成し、ケーブル及びコネクタ付きの超音波探触子５００のコネクタ５３０をコネクタ封入部１１０に収容してそのケーブル５２０をケーブル引出し部１２０から引き出し、開口シール部１３０により開口部１１２をシールした後、両面接着テープ１４６の非接着性テープ１４７を剥離除去し、ケーブル引出し部１２０の上から、ケーブル巻付け帯部１４５を巻き付けて、その部分を両面接着テープ１４６で固定する構造となっている。
【００３５】
この第２の超音波探触子用滅菌・消毒保護袋における作用効果は、第１の超音波探触子用滅菌・消毒保護袋と同様であり、更に、ケーブル引出し部１２０の封止が、その上からケーブル巻付け帯部１４５を巻きつけるだけでできるので、より一層容易になる、という効果がある。
なお、この第２の超音波探触子用滅菌・消毒保護袋の製造方法は、前述したその構造の部分で説明したとおりである。
【００３６】
【発明の効果】
以上説明したように本発明は、超音波探触子用滅菌・消毒保護袋を、コネクタ封入部の開口部分がその縁を延長する方向に広げられてこの縁の延長部分に、この縁に対し設定された幅でコネクタ封入部とつながり、かつ、開口部延長部分の縁とは逆側の重なり合う２枚のシート間がつながったケーブル引出し部を形成し、かつこのケーブル引出し部とつながった２枚のケーブル縛りひも部、又はこれら２枚を溶着してその片面に両面接着テープを接着、配置したケーブル巻付け帯部を形成し、コネクタ封入部の開口部、及びその延長部分に、その重なり合う２枚のシート間を封止する開口シール部を設けて、コネクタ封入部にコネクタを収容し、このコネクタとつながるケーブルをケーブル引出し部に収めて開口シール部でシールした後、ケーブルを、ケーブル引出し部ごと、ケーブル縛りひも部で縛りつけるか、ケーブル巻付け帯部で巻きつける構造とし、ケーブル引出し部の、突出先端部分の幅を、シールしたときにケーブルの周囲に密着する程度の寸法とすることにより、ケーブルを縛りつけ、又はケーブルに巻きついた際に、ケーブル引出し部分にしわが発生するのを防ぐことができて、超音波探触子全体を薬液等に浸して滅菌・消毒する場合でも、コネクタ封入部内に薬液等が浸入するのを防止することができる、という効果がある。
【００３７】
また、このような超音波探触子用滅菌・消毒保護袋は、合成樹脂シートから直接製造することもできるが、市販のファスナー付き合成樹脂製袋を加工して製造することもでき、この場合、製造が容易でかつ低コストとすることができる。
