Description

【０００１】
【発明の属する技術分野】
本発明は、寝たきり老人、入院患者、身障者、その他の自分の意志で排尿をコントロールしたり始末するのが困難な人に装着して排尿を処理する自動排尿処理装置およびそれに用いる尿レシーバに関する。
【０００２】
【従来の技術】
【特許文献１】特開平７−１７１１８２号公報
【特許文献２】特開平１１−１１３９４６号公報
人間は、老化、身体障害、怪我や病気での入院、その他様々な身体の状態によって、自分の意志で排尿をコントロールすることが困難になったり、また尿を自力での後始末が困難になることがある。このようになると、一般的には膀胱に管を直接挿入して採尿したり、紙おむつを使用するようにしている。
【０００３】
膀胱に直接管を挿入する場合には、使用者の不快感も大きく、また尿道や膀胱を傷つけたり感染症を引き起こす可能性が高いなど、専門的な知識と滅菌された専用の器具がないと処理が困難になる。
【０００４】
また、紙おむつは、長時間装着すると尿漏れが起こったり、また装着者の不快感や、蒸れ、被れなどの皮膚疾患を生じることがある。そのため、頻繁な取替えが必要となり、装着者及び介護者の精神的、肉体的負担も多くなる。精神的、肉体的負担は日常生活の中でも非常に大きな割合を占め、その上、経済的な負担も大きくなる。
【０００５】
このような問題を解決するために、尿レシーバ本体に収納された吸水性厚肉シートの収尿材に吸収された尿を真空ポンプによって吸引し尿タンクに導尿するようにしている。真空ポンプは密閉された尿タンク内の空気を吸引して大気圧との差圧により尿導チューブによって収尿材に吸収された尿を尿タンクに尿導する。このような自動排尿処理装置は、例えば、上述の特許文献１、２に記載されている。
【０００６】
【発明が解決しようとする課題】
従来技術は収尿材の尿受面、つまり装着者の排尿部との接触面が大気開放状態になっており、尿だけでなく空気も吸引することになり尿吸引の効率が低下する。このため、尿レシーバ（収尿材）の残尿量が多くなり装着者に不快感を与えることになる。尿レシーバの残尿量を少なくするには真空ポンプの容量を大きくしなければならず、排尿処理装置自体の重量、容積が大きくならざるを得なくなる。
【０００７】
このように、従来技術は尿レシーバの残尿量が多くなり、残尿量を低減しようとすると排尿処理装置が大型かつ重くなるという問題点を有する。
【０００８】
本発明の目的は、尿レシーバからの尿回収率を向上させ、小型かつ軽量化できる自動排尿処理装置およびそれに用いる尿レシーバを提供することにある。
【０００９】
【課題を解決するための手段】
本発明の特徴とするところは、断面コ字型を成し略矩形状の非通気性、非通水性の外皮シートに収尿材を収納し、収尿材の表面に非通気性の表面シートを配置した尿レシーバを用い、外皮シートの底面に穿設されている導尿口から導尿チューブを介して密閉されている尿タンクに真空ポンプにより尿を導くようにしたことにある。
【００１０】
換言すると、本発明は非通気性、非通水性の外皮シートに収尿材を収納し、外皮シートの縁部（脚部）上端を難通気性、通水性の表面シートで覆い、収尿材を外皮シートと表面シートによって通気の気密性（密閉性）を高くして保持し、真空ポンプにより収尿材内の空気圧を低下させて外皮シートの導尿口から導尿チューブを介して尿タンクに尿を導くものである。
【００１１】
本発明に用いる尿レシーバは収尿材を外皮シートと表面シートによって通気の気密性を高くして保持しているので、収尿材は収尿材内の空気圧の低下に伴い圧縮され尿が搾り出されるので尿の回収率が向上し尿レシーバの残尿量を低減できる。尿の回収率が向上すると吸引力の小さい小容量の真空ポンプで収尿材から吸尿できる。したがって、尿レシーバから装着者に不快感を与えることなく尿を回収でき、装置を小型かつ軽量化することができる。
【００１２】
【発明の実施の形態】
本発明の一実施例を図１〜４に示す。図１は本発明の自動排尿処理装置の全体構成図を示し、図２は尿レシーバの詳細構成図、図３は図２のＡ−Ａ断面図、図４は図２のＢ矢視観断面図を示している。なお、図２（ａ）は一部破断して図示している。
【００１３】
図１〜４において、装着者の排尿部から排泄される尿を吸収する尿レシーバ１は略矩形状で長手方向の中央部が幅が狭くなり括れた形状に形成され、表面シート２、収尿材３、外皮シート４およびギャザー５により構成されている。表面シート２は不織布のような軟質可撓性素材で形成され、収尿材３、外皮シート４およびギャザー５も軟質可撓性素材で形成される。
【００１４】
尿レシーバ１を構成する外皮シート４は図２に示すように略矩形状で、長手方向の中央部が幅が狭くなり括れた形状に形成されている。長手方向の中央部が括れた形状にしているのは装着者の股間にフィットするようにするためである。
【００１５】
外皮シート４は幅方向の断面が図３に示すようにコ字型を成し、底面に導尿口４ｂが穿設されている。外皮シート４は長手方向の断面も大きさが異なるだけで図３に示すようにコ字型形状になる。外皮シート４は略矩形状の外形輪郭に沿って縁部（コ字型形状の脚部）４ａが形成されている。
【００１６】
外皮シート４は非通水性、非通気性の薄肉シートで、例えば、ポリエチレンフィルムを素材にして構成されている。外皮シート４は長さが２００〜３００ｍｍ程度で、幅が５０〜１００ｍｍ程度である。なお、外皮シート４は非通水性、非通気性の部材であればよいが、長時間装着した時の蒸れ等に考慮した材質の部材を用いるのが望ましい。
【００１７】
外皮シート４の外面（表面）はポリプロピレン不織布などの表面材（図示せず）がラミネートされ、柔らかな肌触りにして装着者の肌触りの不快感をなくすようにしている。また、外皮シート４の内面は撥水性を有するように表面処理が施されている。
【００１８】
収尿材３は外皮シート４に収納されており、収尿材３の表面（上面）を覆うように通水性、難通気性の表面シート２が配置されている。表面シート２は外皮シート４の縁部（脚部）４ｂの上端に接着して配置されており、外皮シート４と表面シート２によって収尿材３を通気の気密性を高くして保持している。
【００１９】
ここで、表面シート２の難通気性とは、ＪＩＳＬ１０９６の６．２７．１に規定される、一般織物試験方法の通気性Ａ法に従って測定した通気性が、表面シート２の湿潤状態において、０〜１００ｃｃ／ｃｍ^２／秒、好ましくは０〜５０ｃｃ／ｃｍ^２／秒の範囲にあるのが望ましいものである。また、表面シート２の乾燥状態においては、２０〜２００ｃｃ／ｃｍ^２／秒、好ましくは２０〜１００ｃｃ／ｃｍ^２／秒、さらに好ましくは２０〜５０ｃｃ／ｃｍ^２／秒の範囲にあるのが望ましい。
【００２０】
なお、湿潤状態とは下記の式で求められる表面シート２の含水率（％）が１００％以上の状態のことであり、乾燥状態とは２０℃、ＲＨ６０％の雰囲気中に十分に放置して乾燥させた状態、もしくは、いわゆる公定水分率にある状態のことである。
【００２１】

さて、収尿材３は厚みが５ｍｍ程度で、約５００ｍｌの尿を蓄積できるように構成されている。成人の平均的な一回分の排尿量では３００ｍｌ程度の蓄積量があればよいが、装着者が座位の時に人体と座面との間に尿レシーバ１が当たった時の尿レシーバ１に加わる圧力や、股関節を閉じた時に尿レシーバ１が挟まれることによって生じる圧力等によって、尿レシーバ１の蓄尿率低下等を考慮し余裕を持たせた蓄尿量にしている。
【００２２】
表面シート２は、例えば、ポリプロピレン、ポリオレフィン・ポリエステルにコットンを混紡した通水性を有し難通気性の不織布で形成され、装着者の皮膚との摩擦を最少になるようにしている。また、表面シート２として用いる不織布は装着者の排尿部の近辺領域の肌に接する面をメッシュシートにして吸水性、吸汗性を高くし尿をメッシュシートの細かい気孔から速やかに吸収材３に吸収させるようにしている。装着者は尿を速やかに吸収材３に吸収させることにより排尿部近辺の濡れた感触が少なくなる。
【００２３】
外皮シート４の縁部４ａの上端には図３、図４に示すように外皮シート４の外形輪郭の内側に傾斜して植立した立体のギャザー５が形成されている。傾斜植立した立体ギャザー５は装着者の動作や体位移動などによる横漏れを防止する。また、外皮シート４の底面の外面には図２（ｂ）に示すように２本のずれ止テープ（両面テープ）６が設けられている。ずれ止テープ６は装着者の下着に接着し尿レシーバ１のずれを抑制する。
【００２４】
外皮シート４の底面に穿設された導尿口４ｂには導尿チューブ１１ａの一端が接着されている。導尿チューブ１１ｂの一端にワンタッチジョイント１３が取付けられており、ジョイント１３によって導尿チューブ１１ａの他端と導尿チューブ１１ｂの一端が接続される。導尿チューブ１１ａ、１１ｂは軟質可撓性素材で形成され、ワンタッチジョイント１３の軟質材で形成される。
【００２５】
尿タンク２１は蓋２２により密閉されている。導尿チューブ１１ｂの他端は尿タンク２１の蓋２２を貫通して尿タンク２１の気相部２１ａに位置するように配置されている。また、真空ポンプ３１に一端を連結された吸引チューブ１１ｃの他端も尿タンク２１の蓋２２を貫通して尿タンク２１の気相部２１ａに位置するように配置されている。導尿チューブ１１ｃも導尿チューブ１１ａ、１１ｂと同様に軟質可撓性素材で形成されている。
【００２６】
尿タンク２１の容量は、２回分の排尿を蓄えられる５００ｍｌ程度であるが、２００ｍｌ、あるいは夜間などの長時間用として１０００ｍｌにすることもできる。
【００２７】
真空ポンプ３１はモータ３２によって駆動される。モータ３２はバッテリ３３を駆動電源とし、制御基板３４に搭載された制御装置により制御される。真空ポンプ３１の体格は径が３０ｍｍ×７０ｍｍ程で小さく、また、バッテリ３３の電圧は６Ｖ程度である。
【００２８】
収尿材３に尿が吸尿されたことを検知する尿センサ１２は導尿チューブ１１ａに沿って配置され、チューブ１１ａの一端入口付近（導尿口４ｂ付近）で排尿により電気的に導通する。尿センサ１２は電気導体で、抵抗値の変化により装着者の排尿を検知する。尿センサ１２で検知した尿検知信号は真空ポンプ３１を制御する制御基板３４に加えられる。
【００２９】
この構成において、尿レシーバ１は図５に示すように装着者（図示せず）の下着４１内に表面シート２が排尿部に接触するように装着される。尿タンク２１、真空ポンプ３１、モータ３２などは装着者が携帯したり、装着者がベッドに寝ている場合にはベッドの上や下に載置される。
【００３０】
この状態で装着者が排尿すると、尿レシーバ１に排尿された尿は表面シート（不織布）２を通って収尿材３に吸尿される。収尿材３に吸収された尿が外皮シート４の導尿口４ｂに達すると、尿センサ１２が電気的に導通し尿検知信号を制御基板３４に加える。制御基板３４に搭載されている制御装置はモータ３２を起動させ真空ポンプ３１を駆動する。
【００３１】
真空ポンプ３１の駆動により尿タンク２１内の空気が排気されると、収尿材３内の空気圧が低下し導尿口４ｂに負圧が生じる。収尿材３は難通気性の表面シート２と非通気性の外皮シート４によって通気の気密性を保ち保持されているので、導尿チューブ１１ａを介して排気されると収尿材３にも負圧が加わる。
【００３２】
収尿材３は負圧が加わると尿レシーバ１周辺の大気圧との圧力差によって圧縮され図４（ａ）の状態から図４（ｂ）に示すように収縮する。収尿材３が収縮すると溜まっている尿が搾り出され、導尿口４ｂに案内される。導尿口４ｂに案内された尿は負圧によって導尿チューブ１１ａ，１１ｂを介して尿タンク２１に導かれ蓄えられる。
【００３３】
なお、外皮シート４の内面は撥水処理が施されており、収尿材３から搾り出され、収尿材３と外皮シート４との間に達した尿は速やかに導尿口４ａに導かれる。
【００３４】
尿タンク２１に蓄えられた尿はワンタッチジョイント１３により導尿チューブ１１ａと１１ｂの接続を外し尿タンク２１を運んで廃棄する。また、尿レシーバ１は、装着者が約１日使用した後に新しい尿レシーバ１と交換し、交換した古い尿レシーバ１を廃棄する。
【００３５】
このようにして装着者の排尿を処理するのであるが、本発明は収尿材３を難通気性の表面シート２で覆い、外皮シート４と表面シート２によって収尿材３を通気の気密性を高くして保持し真空ポンプ３１により吸尿している。
【００３６】
表面シート２として不織布を使用した本発明による尿レシーバ１を用い、真空ポンプ３１を１２０秒駆動して吸引した場合の吸尿材３からの尿回収率を測定したところ図６の特性ａのようになる。特性ａから明らかなようにのように真空ポンプ３１の吸引力が小さくても８０％弱の回収率が得られる。一方、非通気性の表面シート２が無い場合には特性ｂにようになり、真空ポンプ３１の吸引力を大きくしても６０％弱程度しか回収できなくなっている。
【００３７】
このように、本発明に用いる尿レシーバは収尿材の表面を通水性で難通気性の表面シートで覆うようにしているので、収尿材は収尿材内の空気圧の低下に伴い圧縮されて尿が搾り出されるので尿の回収率が向上し尿レシーバの残尿量を低減できる。尿の回収率が向上すると吸引力の小さい小容量の真空ポンプで収尿材から吸尿できることになる。したがって、尿レシーバが装着者に不快感を与えることなく尿を回収でき、装置を小型かつ軽量化することができる。
【００３８】
また、装置を小型かつ軽量化することができるので、特に携帯用の自動排尿処理装置として用いると顕著な効果を奏し得る。さらに、装置を小型かつ軽量化し、真空ポンプで余分な空気を吸引しないので騒音を小さくできるので夜間に病室で利用しても他人に迷惑をかけることなく尿処理を行える。
【００３９】
図７に尿レシーバ１の他の例を示す。
【００４０】
図７は収尿材３を多層に積層配置した例を示し、収尿材３ａ，３ｂを２層に積層した例を示している。外皮シート４の底面側の収尿材３ｂの吸水性が収尿材３ａよりも高くなるように積層配置している。収尿材３ａは、親水化繊トウ束あるいはスポンジ系の材料で、収尿材３ｂは親水発泡体又は空隙構造体の材料である。
【００４１】
装着者が仰臥位や側臥位、座位など様々な姿勢をとることによって、身体と、床面や座面などとの間に挟まれ、収尿材３の一部が圧縮される。この状態で装着者が排尿すると、尿レシーバ１に排尿された尿が表面シート２を逆戻りすることがある。
【００４２】
図７に収尿材３ａ，３ｂを積層配置し下層の収尿材３ｂの吸水性を高くすることによって、排尿された尿は下層の収尿材３ｂへ収尿され尿が逆戻りするのを防止することができる。
【００４３】
なお、収尿材３は２層でなく多層に積層配置しても同様に尿が逆戻りするのを防止できることは明らかなことである。
【００４４】
本発明の他の実施例を図８〜１０に示す。図８は他の実施例の自動排尿処理装置の全体構成図を示し、図９は尿レシーバの一部破断した詳細構成図、図１０は図９のＣ−Ｄ断面拡大図を示している。図１０の一点鎖線の図示右側はＣ矢視観断面を示し、左側はＤ矢視観断面を示している。
【００４５】
図８〜１０に示す実施例において図１〜４に示す実施例と異なるところは、収尿材３を２層にし、表面シート２に接触する上層の収尿材３ａを幅方向に分割して配置し上層収尿材３ａの間に複数本の蛇腹状のバルーン７を配置したことである。
【００４６】
尿レシーバ１の収尿材３ａ、３ｂは図９、図１０（ａ）に示すように２層に積層して外皮シート４と表面シート２によって通気の気密性を高くして保持されている。上層の収尿材３ａは尿レシーバ１の幅方向に複数に分割され、所定間隔をおいて配置されている。
【００４７】
複数本の蛇腹状バルーン７は収尿材３ａの間に尿レシーバ１の長手方向に配置されている。バルーン７の長さは尿レシーバ１の長手方向の長さと略等しくなる。バルーン７は塩化ビニールなどの軟質可撓性部材で構成されている。複数本の蛇腹状バルーン７の一端（図９の図示上側）は送風チューブ１４ａの一端に接続されている。
【００４８】
送風チューブ１４ａの他端にはワンタッチジョイント１６より送風チューブ１４ｂの一端が接続されている。ワンタッチジョイント１６は送風チューブ１４ｂの一端に取付けられている。送風チューブ１４ｂの他端は真空ポンプ３１に接続されている。なお、送風チューブ１４ｂの他端はバルーン７の送風する場合には真空ポンプ３１の排気口に接続され、バルーン７内の空気を排気する場合には真空ポンプ３１の吸引口に接続されるが図示を簡単にするため一個所に接続して示している。
【００４９】
この構成において、装着者が排尿すると真空ポンプ３１を駆動して尿タンク２１に導き蓄えることは上述の実施例と同じである。この状態においては収尿材３ａとバルーン７は図１０（ａ）に示すようになっている。
【００５０】
制御基板３４に搭載されている制御装置は尿センサ１２から尿検知信号を入力し真空ポンプ３１を起動してから設定時間後に送風チューブ１４ｂの他端を真空ポンプ３１の排気口に接続しバルーン７に送風する。設定時間は装着者の排尿時間により定められ、例えば、３０秒〜６０秒に設定される。
【００５１】
バルーン７は送風されると尿レシーバ１の幅方向に拡張する。収尿材３ａはバルーン７の幅方向拡張により圧縮され、幅方向厚みが漸次小さくなる。バルーン７に送風を続けると、収尿材３ａとバルーン７は図１０（ｂ）に示す状態になる。複数本のバルーン７は図１０（ｂ）の状態になると収尿材３ｂの遮蔽膜を形成する。
【００５２】
収尿材３ｂは上面を表面シート２とバルーン７により覆われるので通気の気密性を一層高くすることができる。したがって、収尿材３ｂは強く圧縮されて尿が搾り出されるので尿の回収率が向上し尿レシーバ１の残尿量を少なくすることができる。
【００５３】
制御基板３４に搭載されている制御装置は真空ポンプ３１による尿吸引の終了後に送風チューブ１４ｂの他端を真空ポンプ３１の吸気口に接続しバルーン７内のバルーン７の中の空気を真空ポンプ３１で吸引して排気する。収尿材３ａとバルーン７は図１０（ａ）に示す状態になる。送風チューブ１４ｂの他端の真空ポンプ３１の排気口と吸気口への接続切替は、通常バルブで行われる。
【００５４】
バルーン７内の空気を全て排出したら真空ポンプ３１を停止し、切替バルブを元に戻して一連の動作を終了する。
【００５５】
このように、図８〜１０に示す実施例においても収尿材からの尿回収率をさらに向上させて尿レシーバの残尿量を低減でき、尿レシーバが装着者に不快感を与えることなく尿を回収でき、装置を小型かつ軽量化することができる。
【００５６】
以上のように、本発明は尿レシーバの収尿材からの尿回収率を向上させ尿レシーバの残尿量を低減できる。尿の回収率が向上すると吸引力の小さい小容量の真空ポンプで収尿材から吸尿できることになる。したがって、尿レシーバが装着者に不快感を与えることなく尿を回収でき、装置を小型かつ軽量化することができる。
【００５７】
また、装置を小型かつ軽量化することができるので、特に携帯用の自動排尿処理装置として用いると顕著な効果を奏し得る。さらに、装置を小型かつ軽量化し、真空ポンプで余分な空気を吸引しないので騒音を小さくできるので夜間に病室で利用しても他人に迷惑をかけることなく尿処理を行える。
【００５８】
なお、上述の実施例は外皮シートと表面シートが非通気性あるいは難通気性としているが、収尿材の通気の気密性を高めれば同様な効果が得られ若干通気性があっても良いことは勿論のことである。
【００５９】
また、外皮シートは断面コ字型としているが、略コ字型であればよくＵ字型や「ひ」字型などの形状であっても明らかなことである。
【００６０】
【発明の効果】
本発明は尿レシーバからの尿回収率を向上させ尿レシーバの残尿量を低減できるので、小容量の真空ポンプにより吸尿でき尿レシーバが装着者に不快感を与えることなく尿を回収でき、装置を小型かつ軽量化することができる。
【００６１】
また、装置を小型かつ軽量化することができるので、特に携帯用の自動排尿処理装置として用いると顕著な効果を奏し得る。さらに、装置を小型かつ軽量化し、真空ポンプで余分な空気を吸引しないので騒音を小さくできるので夜間に病室で利用しても他人に迷惑をかけることなく尿処理を行なえる。

TECHNICAL FIELD OF THE INVENTION
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic urination processing apparatus mounted on a bedridden elderly person, an inpatient, a handicapped person, or another person who has difficulty controlling or cleaning up their own will to process urination, and a urine receiver used therefor.
[0002]
[Prior art]
[Patent Document 1] Japanese Patent Application Laid-Open No. 7-171182 [Patent Document 2] Japanese Patent Application Laid-Open No. 11-113946 [0003] Humans are willing to change their own will according to aging, disability, hospitalization for injury or illness, and various other physical conditions. May make it difficult to control urination, or it may be difficult to clean up urine on its own. In such a case, a tube is generally inserted directly into the bladder to collect urine, or a disposable diaper is used.
[0003]
When inserting a tube directly into the bladder, there is great discomfort for the user, and there is a high possibility of damaging the urethra and bladder and causing infections. Processing becomes difficult.
[0004]
Further, when a disposable diaper is worn for a long time, urine leakage may occur, or discomfort of the wearer, and skin diseases such as stuffiness and cover may occur. Therefore, frequent replacement is required, and the mental and physical burden on the wearer and the caregiver also increases. Mental and physical burdens occupy a very large proportion of everyday life, and the economic burden is also high.
[0005]
In order to solve such a problem, urine absorbed by the urine collecting material of the water-absorbing thick sheet accommodated in the urine receiver body is suctioned by a vacuum pump and guided to the urine tank. The vacuum pump sucks the air in the sealed urine tank and guides the urine absorbed by the urine collecting material by the urine collection tube to the urine tank by a pressure difference from the atmospheric pressure. Such an automatic urination processing apparatus is described in, for example,

Patent Documents

1 and 2 described above.
[0006]
[Problems to be solved by the invention]
In the prior art, the urine receiving surface of the urine collection material, that is, the contact surface with the urination part of the wearer is open to the atmosphere, so that not only urine but also air is sucked, and the efficiency of urine suction is reduced. For this reason, the amount of residual urine in the urine receiver (urine collection material) increases, which gives a discomfort to the wearer. In order to reduce the amount of residual urine in the urine receiver, the capacity of the vacuum pump must be increased, and the weight and volume of the urination processing apparatus itself must be increased.
[0007]
As described above, the conventional technology has a problem that the urine amount of the urine receiver increases, and the urination processing apparatus becomes large and heavy when trying to reduce the residual urine amount.
[0008]
An object of the present invention is to provide an automatic urine disposal apparatus capable of improving the urine collection rate from a urine receiver, reducing the size and weight, and providing a urine receiver used therefor.
[0009]
[Means for Solving the Problems]
The feature of the present invention is that a urine collection material is stored in a substantially rectangular non-breathable, water-impermeable outer skin sheet having a U-shaped cross section, and a non-breathable surface sheet is formed on the surface of the urine collection material. Is arranged so that urine is guided by a vacuum pump from a urine port provided on the bottom surface of the outer skin sheet to a sealed urine tank via a urine tube.
[0010]
In other words, according to the present invention, the urine collecting material is stored in a non-breathable, water-impermeable skin sheet, and the upper end of the edge (leg) of the skin sheet is covered with a non-breathable, water-permeable top sheet. The airtightness (airtightness) of the ventilation is kept high by the outer skin sheet and the topsheet, and the air pressure in the urine collection material is reduced by the vacuum pump, and the urine tank is passed through the urine outlet of the outer skin sheet through the urine tube. Is to guide urine.
[0011]
Since the urine receiver used in the present invention holds the urine collecting material with the airtightness of the ventilation being enhanced by the outer cover sheet and the topsheet, the urine collecting material is compressed as the air pressure in the urine collecting material is reduced and urine is squeezed. As a result, the urine collection rate is improved and the amount of residual urine in the urine receiver can be reduced. When the urine collection rate is improved, urine can be sucked from the urine collecting material by a small-capacity vacuum pump having a small suction force. Therefore, urine can be collected from the urine receiver without causing discomfort to the wearer, and the device can be reduced in size and weight.
[0012]
BEST MODE FOR CARRYING OUT THE INVENTION
One embodiment of the present invention is shown in FIGS. FIG. 1 is an overall configuration diagram of an automatic urination processing apparatus of the present invention, FIG. 2 is a detailed configuration diagram of a urine receiver, FIG. 3 is a cross-sectional view taken along line AA of FIG. 2, and FIG. FIG. FIG. 2A is partially cut away.
[0013]
1 to 4, a urine receiver 1 for absorbing urine excreted from a urination part of a wearer is formed in a substantially rectangular shape, a central portion in a longitudinal direction having a narrow width and a constricted shape, and a top sheet 2 and urine collection. It is composed of a material 3, a skin sheet 4 and a gather 5. The topsheet 2 is formed of a soft flexible material such as a nonwoven fabric, and the urine collecting material 3, the outer cover sheet 4 and the gather 5 are also formed of a soft flexible material.
[0014]
As shown in FIG. 2, the outer cover sheet 4 constituting the urine receiver 1 is formed in a substantially rectangular shape, and has a narrowed central portion in the longitudinal direction and a narrowed shape. The reason why the central portion in the longitudinal direction is constricted is to fit the crotch of the wearer.
[0015]
The outer skin sheet 4 has a U-shaped cross section in the width direction as shown in FIG. 3, and a urethral opening 4 b is formed in the bottom surface. The outer cover sheet 4 has a U-shape as shown in FIG. The outer cover sheet 4 is formed with an edge portion (U-shaped leg portion) 4a along a substantially rectangular outer contour.
[0016]
The outer cover sheet 4 is a non-water-permeable, non-breathable thin sheet, for example, made of a polyethylene film. The outer cover sheet 4 has a length of about 200 to 300 mm and a width of about 50 to 100 mm. The outer cover sheet 4 may be a non-permeable or non-permeable member, but it is desirable to use a member made of a material that takes into account stuffiness when the cover sheet is worn for a long time.
[0017]
The outer surface (surface) of the outer cover sheet 4 is laminated with a surface material (not shown) such as a polypropylene non-woven fabric, so as to have a soft touch so that the wearer does not feel uncomfortable. The inner surface of the outer cover sheet 4 is subjected to a surface treatment so as to have water repellency.
[0018]
The urine collecting material 3 is housed in a skin sheet 4, and a water-permeable and air-impermeable top sheet 2 is arranged so as to cover the surface (upper surface) of the urine collecting material 3. The topsheet 2 is adhered to the upper end of the edge (leg) 4b of the skin sheet 4 and holds the urine collection material 3 with the ventilation sheet airtight by the skin sheet 4 and the topsheet 2. I have.
[0019]
Here, the impermeability of the topsheet 2 refers to the permeability measured in accordance with the permeability A method of the general textile test method specified in 6.27.1 of JIS L 1096, when the topsheet 2 is in a wet state. , 0-100 cc / cm ² / sec, preferably 0-50 cc / cm ² / sec. When the topsheet 2 is in a dry state, it is desirably in the range of 20 to 200 cc / cm ² / sec, preferably 20 to 100 cc / cm ² / sec, more preferably 20 to 50 cc / cm ² / sec.
[0020]
Note that the wet state is a state in which the water content (%) of the surface sheet 2 determined by the following formula is 100% or more, and the dry state is that the surface sheet 2 is sufficiently left in an atmosphere at 20 ° C. and RH 60%. It is a state in which it has been dried, or has a so-called official moisture content.
[0021]

The urine collecting material 3 has a thickness of about 5 mm and is configured to accumulate about 500 ml of urine. The average volume of urination for an adult is about 300 ml, but the pressure applied to the urine receiver 1 when the urine receiver 1 hits between the human body and the seating surface when the wearer is in the sitting position. In addition, the urine collection amount is set to have a margin in consideration of a decrease in the urine collection rate of the urine receiver 1 due to pressure or the like generated when the urine receiver 1 is pinched when the hip joint is closed.
[0022]
The topsheet 2 is made of, for example, a water-permeable, air-impermeable nonwoven fabric obtained by blending cotton with polypropylene, polyolefin / polyester, and minimizes friction with the wearer's skin. In addition, the nonwoven fabric used as the topsheet 2 has a mesh sheet on the surface in contact with the skin in the vicinity of the urination area of the wearer to increase water absorption and sweat absorption, thereby allowing urine to be quickly absorbed by the absorbent material 3 through fine pores of the mesh sheet. Like that. The wearer quickly absorbs the urine into the absorbent material 3 so that the wet feeling near the urination part is reduced.
[0023]
At the upper end of the edge 4a of the outer cover sheet 4, as shown in FIGS. 3 and 4, there is formed a three-dimensional gather 5 inclined and planted inside the outer contour of the outer cover sheet 4. As shown in FIG. The three-dimensional gathers 5 that are slopingly placed prevent sideways leakage due to the wearer's movement or body position. In addition, two slip preventing tapes (double-sided tape) 6 are provided on the outer surface of the bottom surface of the outer cover sheet 4 as shown in FIG. The slip prevention tape 6 adheres to the wearer's underwear and suppresses the shift of the urine receiver 1.
[0024]
One end of a urine guide tube 11a is adhered to a urine guide port 4b formed in the bottom surface of the outer cover sheet 4. A one-touch joint 13 is attached to one end of the urine guide tube 11b, and the other end of the urine guide tube 11a is connected to one end of the urine guide tube 11b by the joint 13. The

urine guide tubes

11a and 11b are formed of a soft flexible material, and are formed of a soft material of the one-touch joint 13.
[0025]
The urine tank 21 is sealed by a lid 22. The other end of the urine guide tube 11b is arranged so as to penetrate the lid 22 of the urine tank 21 and to be located in the gas phase portion 21a of the urine tank 21. The other end of the suction tube 11 c having one end connected to the vacuum pump 31 is also disposed so as to pass through the lid 22 of the urine tank 21 and to be located in the gas phase portion 21 a of the urine tank 21. The urine guide tube 11c is also formed of a soft and flexible material, like the

urine guide tubes

11a and 11b.
[0026]
The capacity of the urine tank 21 is about 500 ml capable of storing two urinations, but may be 200 ml or 1000 ml for a long time such as at night.
[0027]
The vacuum pump 31 is driven by a motor 32. The motor 32 uses a battery 33 as a driving power source and is controlled by a control device mounted on a control board 34. The size of the vacuum pump 31 is as small as about 30 mm × 70 mm in diameter, and the voltage of the battery 33 is about 6V.
[0028]
A urine sensor 12 for detecting that urine has been sucked into the urine collecting material 3 is disposed along the urine introduction tube 11a, and is electrically connected to the urine near the one end entrance of the tube 11a (near the urine introduction port 4b) by urination. . The urine sensor 12 is an electric conductor, and detects urination of the wearer based on a change in resistance value. The urine detection signal detected by the urine sensor 12 is applied to a control board 34 for controlling the vacuum pump 31.
[0029]
In this configuration, the urine receiver 1 is mounted in an undergarment 41 of a wearer (not shown) so that the topsheet 2 comes into contact with the urination part as shown in FIG. The urine tank 21, the vacuum pump 31, the motor 32, and the like are carried by the wearer, or placed on or under the bed when the wearer is sleeping on the bed.
[0030]
When the wearer urinates in this state, the urine discharged into the urine receiver 1 passes through the topsheet (nonwoven fabric) 2 and is absorbed by the urine collecting material 3. When the urine absorbed by the urine collecting material 3 reaches the urine guide port 4b of the outer cover sheet 4, the urine sensor 12 is electrically connected and applies a urine detection signal to the control board 34. The control device mounted on the control board 34 starts the motor 32 and drives the vacuum pump 31.
[0031]
When the air in the urine tank 21 is exhausted by driving the vacuum pump 31, the air pressure in the urine collection material 3 decreases, and a negative pressure is generated in the urine introduction port 4b. Since the urine collecting material 3 is kept air-tight by the air-impermeable top sheet 2 and the non-breathable outer skin sheet 4, the urine collecting material 3 is also exhausted through the urine introduction tube 11 a. Negative pressure is applied.
[0032]
When a negative pressure is applied, the urine collecting material 3 is compressed by a pressure difference from the atmospheric pressure around the urine receiver 1 and contracts from the state of FIG. 4A as shown in FIG. 4B. When the urine collecting material 3 contracts, the accumulated urine is squeezed out and guided to the urine introduction port 4b. The urine guided to the urine introduction port 4b is guided to the urine tank 21 via the

urine introduction tubes

11a and 11b by negative pressure and stored.
[0033]
The inner surface of the outer cover sheet 4 is subjected to a water-repellent treatment, so that urine that is squeezed out of the urine collection material 3 and reaches between the urine collection material 3 and the outer cover sheet 4 is immediately guided to the urine introduction port 4a. I will
[0034]
The urine stored in the urine tank 21 is disconnected by the one-touch joint 13 between the

urine guiding tubes

11a and 11b, and the urine tank 21 is carried and discarded. The urine receiver 1 is replaced with a new urine receiver 1 after the wearer uses it for about one day, and the replaced old urine receiver 1 is discarded.
[0035]
In this way, the urination of the wearer is treated. In the present invention, the urine collection material 3 is covered with the air-impermeable top sheet 2, and the outer collection sheet 4 and the top sheet 2 allow the urine collection material 3 to be air-tight. Is held high and urine is sucked by the vacuum pump 31.
[0036]
Using the urine receiver 1 according to the present invention using a nonwoven fabric as the topsheet 2, the vacuum pump 31 was driven for 120 seconds to measure the urine recovery rate from the urine absorbing material 3 when suction was performed. become. As is apparent from the characteristic a, even if the suction force of the vacuum pump 31 is small, a recovery rate of less than 80% can be obtained. On the other hand, when the non-breathable topsheet 2 is not provided, the characteristic becomes the characteristic b, and even if the suction force of the vacuum pump 31 is increased, only about 60% can be collected.
[0037]
As described above, since the urine receiver used in the present invention covers the surface of the urine collection material with the water-permeable and air-impermeable topsheet, the urine collection material is compressed as the air pressure in the urine collection material decreases. Since urine is squeezed, the recovery rate of urine is improved and the amount of residual urine in the urine receiver can be reduced. When the urine collection rate is improved, urine can be sucked from the urine collecting material by a small-capacity vacuum pump having a small suction force. Therefore, the urine receiver can collect urine without causing discomfort to the wearer, and the device can be reduced in size and weight.
[0038]
Further, since the apparatus can be reduced in size and weight, a remarkable effect can be obtained particularly when the apparatus is used as a portable automatic urination processing apparatus. Furthermore, since the apparatus can be reduced in size and weight, and the excess air is not sucked by the vacuum pump, the noise can be reduced. Therefore, even if the apparatus is used in a hospital room at night, urine can be treated without disturbing others.
[0039]
FIG. 7 shows another example of the urine receiver 1.
[0040]
FIG. 7 shows an example in which the urine collecting materials 3 are arranged in multiple layers, and an example in which the

urine collecting materials

3a and 3b are stacked in two layers. The urine collecting material 3b on the bottom surface side of the outer cover sheet 4 is laminated and arranged so that the water absorption of the urine collecting material 3b is higher than that of the urine collecting material 3a. The urine collecting material 3a is a hydrophilic fiberized tow bundle or a sponge-based material, and the urine collecting material 3b is a material of a hydrophilic foam or a void structure.
[0041]
When the wearer takes various postures such as a supine position, a lateral position, and a sitting position, the wearer is sandwiched between the body and a floor surface or a sitting surface, and a part of the urine collecting material 3 is compressed. When the wearer urinates in this state, urine discharged into the urine receiver 1 may return to the topsheet 2 in some cases.
[0042]
In FIG. 7, the

urine collection materials

3a and 3b are stacked and arranged so as to increase the water absorption of the lower urine collection material 3b, thereby preventing the excreted urine from being collected by the lower urine collection material 3b and returning the urine. can do.
[0043]
It is apparent that the urine can be prevented from returning in the same manner even when the urine collecting material 3 is arranged in a multilayer structure instead of a two-layer structure.
[0044]
Another embodiment of the present invention is shown in FIGS. FIG. 8 is an overall configuration diagram of an automatic urine disposal apparatus according to another embodiment, FIG. 9 is a detailed configuration diagram of a urine receiver partially cut away, and FIG. 10 is an enlarged cross-sectional view taken along line CD of FIG. The right side of the dashed line in FIG. 10 shows a cross section viewed from the arrow C, and the left side shows a cross section viewed from the arrow D.
[0045]
The difference between the embodiment shown in FIGS. 8 to 10 and the embodiment shown in FIGS. 1 to 4 is that the urine collecting material 3 is divided into two layers, and the upper urine collecting material 3 a in contact with the topsheet 2 is divided in the width direction. That is, a plurality of bellows-shaped balloons 7 are arranged between the upper urine collecting materials 3a.
[0046]
The

urine collecting materials

3a and 3b of the urine receiver 1 are stacked in two layers as shown in FIGS. 9 and 10 (a), and are held by the outer cover sheet 4 and the top sheet 2 with high airtightness. The urine collecting material 3a in the upper layer is divided into a plurality in the width direction of the urine receiver 1 and arranged at predetermined intervals.
[0047]
A plurality of bellows-shaped balloons 7 are arranged in the longitudinal direction of the urine receiver 1 between the urine collection materials 3a. The length of the balloon 7 is substantially equal to the length of the urine receiver 1 in the longitudinal direction. The balloon 7 is made of a soft flexible member such as vinyl chloride. One end (the upper side in FIG. 9) of the plurality of bellows-shaped balloons 7 is connected to one end of a blower tube 14a.
[0048]
One end of the blower tube 14b is connected to the other end of the blower tube 14a via a one-touch joint 16. The one-touch joint 16 is attached to one end of the blower tube 14b. The other end of the blower tube 14b is connected to the vacuum pump 31. The other end of the blower tube 14b is connected to an exhaust port of the vacuum pump 31 when blowing the balloon 7, and is connected to a suction port of the vacuum pump 31 when exhausting the air in the balloon 7. Are connected to one place for simplicity.
[0049]
In this configuration, when the wearer urinates, the vacuum pump 31 is driven to guide and store the urine in the urine tank 21 as in the above-described embodiment. In this state, the urine collecting material 3a and the balloon 7 are as shown in FIG.
[0050]
The control device mounted on the control board 34 inputs the urine detection signal from the urine sensor 12 and starts the vacuum pump 31, connects the other end of the blower tube 14 b to the exhaust port of the vacuum pump 31 after a set time, and connects the balloon 7. To blow. The set time is determined by the urination time of the wearer, and is set, for example, to 30 seconds to 60 seconds.
[0051]
When the balloon 7 is blown, it expands in the width direction of the urine receiver 1. The urine collecting material 3a is compressed by expanding the balloon 7 in the width direction, and the thickness in the width direction gradually decreases. When the air is continuously blown to the balloon 7, the urine collection material 3a and the balloon 7 are in a state shown in FIG. The plurality of balloons 7 form a shielding film of the urine collecting material 3b in the state shown in FIG. 10B.
[0052]
Since the upper surface of the urine collecting material 3b is covered with the topsheet 2 and the balloon 7, the airtightness of ventilation can be further enhanced. Therefore, the urine collecting material 3b is strongly compressed and urine is squeezed out, so that the urine collection rate is improved and the amount of residual urine in the urine receiver 1 can be reduced.
[0053]
The control device mounted on the control board 34 connects the other end of the blower tube 14b to the suction port of the vacuum pump 31 after the completion of urine suction by the vacuum pump 31, and discharges air in the balloon 7 inside the balloon 7 into the vacuum pump 31. Suction and exhaust. The urine collecting material 3a and the balloon 7 are in the state shown in FIG. The connection of the other end of the blower tube 14b to the exhaust port and the intake port of the vacuum pump 31 is switched by a normal valve.
[0054]
When all the air in the balloon 7 has been exhausted, the vacuum pump 31 is stopped, the switching valve is returned to its original position, and a series of operations is completed.
[0055]
As described above, also in the embodiment shown in FIGS. 8 to 10, the urine collection rate from the urine collecting material can be further improved to reduce the amount of residual urine in the urine receiver, and the urine receiver does not cause discomfort to the wearer. Can be collected, and the device can be reduced in size and weight.
[0056]
As described above, the present invention can improve the urine collection rate from the urine collection material of the urine receiver and reduce the amount of residual urine in the urine receiver. When the urine collection rate is improved, urine can be sucked from the urine collecting material by a small-capacity vacuum pump having a small suction force. Therefore, the urine receiver can collect urine without causing discomfort to the wearer, and the device can be reduced in size and weight.
[0057]
Further, since the apparatus can be reduced in size and weight, a remarkable effect can be obtained particularly when the apparatus is used as a portable automatic urination processing apparatus. Furthermore, since the apparatus can be reduced in size and weight, and the excess air is not sucked by the vacuum pump, the noise can be reduced. Therefore, even if the apparatus is used in a hospital room at night, urine can be treated without disturbing others.
[0058]
In the above-described embodiment, the outer cover sheet and the topsheet are non-permeable or impervious to air. However, if the air-tightness of the urine collecting material is increased, the same effect can be obtained and the air-permeable material may be slightly permeable. Of course.
[0059]
Further, although the outer cover sheet has a U-shaped cross section, it may be U-shaped or "H" -shaped as long as it is substantially U-shaped.
[0060]
【The invention's effect】
Since the present invention can improve the urine collection rate from the urine receiver and reduce the amount of residual urine in the urine receiver, urine can be sucked by a small-volume vacuum pump, and the urine receiver can collect urine without giving discomfort to the wearer, The device can be reduced in size and weight.
[0061]
Further, since the apparatus can be reduced in size and weight, a remarkable effect can be obtained particularly when the apparatus is used as a portable automatic urination processing apparatus. Furthermore, since the apparatus is small and lightweight, and the excess air is not sucked by the vacuum pump, the noise can be reduced, so that urine can be processed without disturbing others even when used in a hospital room at night.
