【０００５】
【発明の実施の形態】
以下、本発明の実施例を図面に基いて説明する。図面において、図１は本発明によるシャワー入浴洗浄装置の第１実施例を示す斜視図、図２は本発明による給湯装置の説明用配管図、図３はアキュムレーターの断面図、図４は図３のＩＶ−ＩＶ断面図、図５はアキュムレーターの第２実施例の断面図、図６は図５のＶＩ−ＶＩ断面図である。
【０００６】
図１において、１はＦＲＰ（繊維強化プラスチック）製の本体であり、前面（左面）及び下面が開口した箱状に形成し、該本体１の前面をＦＲＰ製のドア２により開閉し、この部から車椅子に乗せた入浴者を出入りさせる。本体１の上壁の前部側に平面視Ｕ形の窓孔３を形成し、この窓孔３から入浴者の頭部を露出させる。上記本体１の内面に多数のノズル４を分散させて取り付ける。各ノズル４のうち本体内の最後部に取り付けるノズル４ａは噴出方向を適宜調節して入浴者の陰部及び肛門部に対応させることができる可動ノズルとする。
【０００７】
上記本体１の周壁は内壁、外壁の二重壁構造とし、これら内外壁の空間部に上記各ノズル４に温水を供給する導入管５を配管する。この導入管５は、本体１の下部に沿うＵ字形に湾曲した大径かつプラスチック製の親管６に可橈性かつ小径の枝管（ホース）７を多数並列に接続し、各枝管７の先端を上記各ノズル４に接続する。上記親管６の後部（図１において右部）に外部との接続口８を取り付け、また、該親管６の後部下部に自動排水弁９を取り付ける。この自動排水弁９は上記親管６内の圧力が所定値以上の際には閉作動し、該圧力が所定値以下になった際に開作動するようになっている。
【０００８】
１０は車輪１１によって任意の位置に移動できる可動台であり、上記本体１に湯を供給する補機類が装備される。この可動台１０は、下部に棚１２を、上部に直方体状の収容ケース１３を有する。上記棚１２には消毒液タンク１４及び洗浄液タンク１５を着脱可能に載置し、収容ケース１３にはその側部に２個のハンドシャワー１６，１６を着脱可能に係止し、上面に操作盤１７を設け、内部に給湯装置２５及び制御装置４５を収容する。
【０００９】
上記操作盤１７は、図２の上部に示すように、正面側に介護者が操作する始動スイッチ１８、湯路をハンドシャワー１６側に切り換えるハンドシャワースイッチ１９、湯路をノズル４側に切り換える入浴スイッチ２０、及湯に消毒液又は洗浄液を混入させる混合スイッチ２１を設け、背面側に準備中を示す表示ランプ２２、及び湯温を示す温度表示器２３を設けてなる。
【００１０】
上記給湯装置２５は図２の下部に示すようになっている。即ち、ボイラーから送られる湯２６と水道管から送られる水２７とを混合弁２８により所定の比率で混合させ、この部で約３３．５℃〜４３．５℃の湯（洗浄湯）２６ａを生成する。ここで生成された湯（洗浄湯）２６ａをアキュムレーター２９内に導入し、この部で上記洗浄湯２６ａを一時的に滞留させて温度を平均化させ、この平均化させた湯（洗浄湯２６ｂ）を本管３０に向けて送る。なお、ボイラーに湯の温度調節器を有する場合には、該ボイラーからの湯を直接上記アキュムレーター２９に、又は本管３０に供給する。
【００１１】
上記本管３０の上流側（右部）に排出管３１を分岐させて接続し、上記本管３０に湯温を検知する温度センサー３２を、また上記排出管３１に温度検知弁（電磁弁）３３を取り付ける。この温度検知弁３３は、上記温度センサー３２の信号を入力する制御装置４５からの指令によって開閉されるもので、湯温が設定温度以下又は以上の際には開作動されて該湯を上記排出管３１から外部に排出させ、湯温が設定温度になった際には閉作動されて該湯を本管３０内に流通させるようになっている。
【００１２】
上記本管３０の下流側（左部）にハンドシャワー１６が接続される分岐管３４、及びバイパス管３５を接続し、上記本管３０の下流側及び上記分岐管３４の基部にそれぞれ第１電磁弁３６、第２電磁弁３７を取り付け、上記バイパス管３５には下流側に向けて第３電磁弁３８、サイフォンインジェクター３９及び逆止弁４０を取り付け、サイフォンインジェクター３９にニードル弁（絞り弁）４１を介して吸引ホース（導入ホース）４２を接続する。この吸引ホース４２は前述の可動台１０に載置した消毒液タンク１４又は洗浄液タンク１５内に選択して挿入される。上記本管３０の下流端部に出湯口４３を取り付け、該出湯口４３と前述した本体１側の導入口８とを、図１に示すように、可撓性の供給ホース４４によって接続する。
【００１３】
図２において、４５は制御装置であり、前述した操作盤１７で選択される各スイッチ１８〜２１の信号を入力して上記各第１電磁弁３６〜第３電磁弁３８を以下の如く開閉制御する。即ち、始動スイッチ１８がオン操作されると、各第１電磁弁３６〜第３電磁弁３８を閉作動させ、この状態で温度センサー３２の信号を入力する。該温度センサー３２が設定された温度以外（低温又は異常高温）の場合は温度検知弁３３を開作動させて混合弁２８から導入される湯を排出管３１を介して外部に排出させ、同時に準備中の表示ランプ２２を点灯させる。
【００１４】
上記温度センサー３２が設定された温度、例えば４２℃になると上記温度検知弁３３を閉作動させ、同時に温度表示器２３に設定温度「４２」を表示するとともに準備中の表示ランプ２２を消灯させる。また、第２電磁弁３７のみの開作動を許容する。この状態で介護者がハンドシャワースイッチ１９をオン操作すると、ハンドシャワー１６から湯が流出し、該介護者は湯温を感触で確認することができ、これを確認した後、入浴者の頭髪を洗髪あるいは顔面部を洗浄する。この場合、ハンドシャワー１６のヘッド１６ａには、図９に示すように、ヘッドカバー９０を被せておく。このヘッドカバー９０は多数の小孔９０ａが明けられた可撓性のシートにより円筒状に形成し、両端をゴム紐９０ｂで絞ってなり、ヘッド１６ａから噴出する湯の飛散を上記ヘッドカバー９０により規制して小孔９０ａから緩やかに流出させ、湯が不用意に入浴者の顔面部に当たるのを防止する。
【００１５】
この状態で介護者が上記入浴スイッチ２０をオン操作すると、第２電磁弁３６が開き、湯（洗浄湯）が本管３０の出湯口４３から供給ホース４４を介して本体１側の導入管５に導入され、各ノズル４から所定温度の湯が噴出し、本体１内に収容した入浴者（患者）の身体を加温することになる。また、吸引ホース４２を消毒液タンク１４内に挿入し、混合スイッチ２０をオン操作すると、本管３０内に消毒液が混入し、消毒液の混入した温水が上記各ノズル４から噴出して上記入浴者を加温しながら消毒する。また、吸引ホース４２を洗浄液タンク１５内に挿入して上記混合スイッチ２０をオン操作すると、本管３０内に洗浄液が混入し、洗浄液の混入した温水が上記各ノズル４から噴出して上記入浴者を加温しながら洗浄することになる。
【００１６】
上記入浴者の入浴が終了し、始動スイッチ１８をオフ操作すると、制御装置からの指令によって各第１電磁弁３６〜第３電磁弁３８が閉作動され、本体１への給湯が停止する。この場合、本体１側の導入管５内に滞留している湯は、親管６内の圧力低下により自動排水弁９が開き、該導入管５内に滞留している湯が外部に排出され、次回の入浴時にノズル４から冷水が噴出するのを防止する。
【００１７】
前述したアキュムレーター２９は図３及び図４に示すようになっている。図３、図４において、５０は密閉されて上下に起立する円筒状のケースであり、該ケース５０内の上部軸心部に前述した混合弁２８からの湯２６ａを流入させる小径の流入管５１を挿通固定し、該流入管５１の外周部に多数の出口５２を明ける。この出口５２は、図４に示すように、流入管５１及びケース５０に対して接線方向に明け、湯を旋回させながらケース５０内に流入させる。
【００１８】
上記流入管５１の下端にこれよりも大径の迂回容器５３を懸垂固定する。この迂回容器５３は上部が閉塞されかつ下部が開口した倒立コップ状とし、その下端をケース５０の底面が上方に離間させる。また、上記ケース５０の下部にその下面軸心部から上記迂回容器５３内に嵌合する流出管５５を起立固定する。この流出管５５の上端は上記迂回容器５３の上部に位置させ、流出管５５の下端は前述した本管３０に接続する。図３において、５４は迂回容器５３の上面に明けた排水用の小孔５４、５６は上記流出管５５の下部に明けた排水用の小孔である。
【００１９】
上記アキュムレーター２９は図５及び図６に示すようにしてもよい。即ち、流入管５１ａをＬ型に屈曲させてケース５０の上部外周部に取り付けるとともに、該流入管５１ａの出口５２ａを図６に示すように、ケース５０に対して接線方向に向ける。また、倒立コップ状の迂回容器５３ａをケース５０内の底部中心部に起立固定し、その下部に多数の窓孔５７を明ける。この迂回容器５３ａの上面５３ｂは流出管５５の上端から大きく上方に離間させ、該迂回容器５３ａの周壁であってかつ上記流出管５５の上端と対応する高さ位置に排水用の小孔５４ａを形成する。これにより上記迂回容器５３ａ内の上部に密閉された空気蓄圧室（チャンバー）５８を形成し、該空気蓄圧室５８により水管内に発生する水圧衝撃（ウォーターハンマー）を防止する。
【００２０】
図７はシャワー入浴洗浄装置の第２実施例を示す。図７において、６０はシャワー入浴洗浄装置、６１は伸縮可能な蛇腹筒形の本体である。この本体６１は、右部側の支持台６２に硬質のプラスチック製の保持ケース６３を起立支持し、該保持ケース６３の左部（前部）に硬質のプラスチック材により左面が開口した短尺な円筒状の格納ケース６４を固定し、該格納ケース６４に蛇腹筒からなる伸縮筒体６５を左方に向けて出没可能に接続する。
【００２１】
上記伸縮筒体６５は、円筒状に形成した可撓性かつ非通水性のシート筒内にリング状の芯材６６を前後方向に所定ピッチで配列固定し、シートの下部に小径の排水孔（符号省略）を前後方向に多数明けてなる。上記伸縮筒体６５の前端（左端）に硬質プラスチック製の口環６７を接続する。この口環６７は下部に車輪６８を取り付けて左右（前後）方向に移動させて上記伸縮筒体６５を伸縮作動させる。
【００２２】
上記伸縮筒体６５内の上部と下部とに上記芯材６６を介して多数のノズル６９を取付け、該各ノズル６９を伸縮筒体６５内で螺旋状に巻回した導入ホース（導入管）７０により直列に接続し、この導入ホース７０の右端を保持ケース６３の右面（後面）に取り付けた導入口７１に接続する。この導入口７１と前述した可動台１０側に装備した給湯装置２５の出湯口４３とを可撓性の供給ホース４４を介して接続する。
【００２３】
図７において、７５は入浴者（患者）Ａを寝かせて上記本体６１内に収容するストレッチャーであり、左右（前後）方向に延びる枠形の下部フレーム７６の両側に上記伸縮筒体６５を摺動可能に支持するガイドレール７７を取付け、該下部フレーム７６の左端部に起立支持した支柱７８に枠状の上部フレーム７９を右方（前方）に向けて取付け、該上部フレーム７９にネット２９（図示省略）を取り付けてなり、このネットに入浴者Ａを寝かせ、該入浴者Ａを上記口環６７側から本体６１内に収容する。
【００２４】
図８はシャワー入浴洗浄装置の第３実施例を示す。図８において、８０はシャワー入浴洗浄装置、８１はその本体である。この本体８１は上面が開口した容器状の収容体８２及び該収容体の上面を覆うカバー８５からなる。収容体８２は軟質プラスチックシート性の空気袋（シリンダー）によりマット部８３と該マット部８３の周辺から起立する周壁部８４とを一体に有する前後方向に細長い容器状に形成され、内部に一人の入浴者（患者）Ａが寝た姿勢で収容できる容積とし、マット部８３はその上面を前部から後部に向けて下り傾斜させ、その後端部に排水管８３ａを接続する。
【００２５】
上記カバー８５は折畳み可能にして収容体８２内に嵌合させ、拡開した際に収容体８２内に寝かせた入浴者Ａの頭部を除く身体部を包囲するようになっている。即ち、逆Ｕ字状に湾曲させた多数のパイプ製の芯材８６を前後に配列してその両端を短尺な左右一対の連結体８７に前後方向に回動可能に連結し、これらの各芯材８６を水平面上にて互いに離間させてその外周を可撓性かつ非通水性のシート８８により包囲するとともに、該シート８８を上記各芯材８６に連結する。そして、上記各芯材８６を連結体８７を中心として上方に回動させて面状に折畳めるようにする。
【００２６】
上記各芯材８６の長さは、図８に示すように、前部から後部に向けて所定の比率で次第に短くし、拡開したシート１３が前部の高い側面視略台形状となるようにする。上記カバー８５の天井部に位置する中間部の３個の芯材８６の幅方向中心部にノズル８９を取り付け、また、一方の連結体８７内に上記中間部の３個の芯材８６と連通する導入口８７ａを形成する。この導入口８７ａと前述した可動台１０側に装備した給湯装置２５の出湯口４３とを可撓性の供給ホース４４を介して接続し、上記給湯装置２５から所定温度の湯を上記供給ホース４４を介して上記中間部の芯材８６に供給し、各ノズル８９から湯を収容体８２内の入浴者Ａに向けて噴出させる。
【００２７】
なお、本発明による本体は、入浴者が健全者あるいは介護を要しない軽い身障者である場合においては、例えば内部に多数のノズルを有する蛇腹筒を上方（天井部）から伸縮可能に垂下させて入浴者の頭部及び身体部の全域を収容するようにしてもよい。
【００２８】
【発明の効果】
以上の説明から明らかな如く、本発明の請求項１に係る発明は、入浴者を収容してその内面に設けた多数のノズルから温水を噴出させる本体と、給湯装置、ハンドシャワー、操作盤等の補機類を一括して装備した可動台とを設け、可動台側から可撓性のホースを介して上記本体側に湯を供給するようにしたので、本体の構造が簡素になり、本体設計の自由度が高くなるとともに、介護者が操作するハンドシャワー及び操作盤を介護者の移動する位置に容易に移動させることができる。また、移動容易な可動台に補機類を一括して装備したので、これらの組み立て及び保守点検が容易になる。
また、請求項２に係る発明は、供給源側から送られる湯がアキュムレーター部で一時的に滞留されて湯温のばらつきが解消されるとともに、アキュムレーターから本管に向かう湯が温度検知弁により設定温度に保持され、本体及びハンドシャワーに安定した湯が供給されることになる。
また、請求項３及び請求項４に係る発明は、アキュムレーター内を流通する湯が流入管及び迂回容器によってアキュムレーター内を旋回及び蛇行運動し、湯温のばらつきを効率よく解消することができる。
また、請求項５及び請求項６に係る発明は、本管に消毒液、洗浄液を混入させることができ、また、消毒液タンク及び洗浄液タンクが可動台によって給湯装置とともに移動するので、作業時の運搬労力が軽減することになる。
