Description

生体排液を収容するための容器Container for storing biological drainage
 本発明は、尿などの生体排液をゲルの状態で収容するための容器に関する。 The present invention relates to a container for storing a biological drainage such as urine in a gel state.
 尿などの生体排液を一時的に収容し、その量を計測したり性状を観察したりするための医療用の容器が医療機関等で広く使用されている。当該容器は通常可撓性のプラスチック製シートからなり、尿を収容するものは「蓄尿バッグ」と呼ばれている。泌尿器の機能が低下した患者などのように患者の意思で排尿できないとき、尿道から膀胱へネラトンカテーテルや導尿用バルーンカテーテルの先端を留置し、このカテーテルの基端に導尿チューブを接続し、このチューブを介して蓄尿バッグへと尿を収容する。 Medical containers for temporarily storing biological effluents such as urine and measuring the amount or observing their properties are widely used in medical institutions and the like. The container is usually made of a flexible plastic sheet, and a container for storing urine is called a “urine storage bag”. When urination cannot be performed at the patient's will, such as in patients with reduced urinary function, place the tip of a nelaton catheter or urinary balloon catheter from the urethra to the bladder, and connect a urinary tube to the proximal end of this catheter. Urine is stored in the urine storage bag through this tube.
 現在、蓄尿バッグは数週間使いまわしされるのが一般的であり、臭いや雑菌の問題がしばしば指摘されてきた。また、現在の蓄尿バッグでは、尿を廃棄する際、蓄尿バッグの排尿口からバケツや紙コップへと一旦バッグ内の尿を回収し、それをトイレや***口に流して廃棄するのが一般的である。しかし、このように尿を液状のまま廃棄すると尿を回収する際に尿が周囲環境および医療従事者へと飛散するおそれがあり衛生的ではない。そのため、蓄尿バッグの内部に尿を吸収してゲル化する材料を配置し、該材料が少なくとも廃棄時までに尿を吸収してゲル化する蓄尿バッグが検討されている。 Currently, urine storage bags are generally used for several weeks, and problems of odor and bacteria have often been pointed out. In addition, with the current urine storage bag, when discarding urine, it is common to collect the urine in the bag from the urine outlet of the urine storage bag to a bucket or paper cup and then drain it to the toilet or excretion port for disposal. It is. However, if the urine is discarded in a liquid state as described above, the urine may be scattered to the surrounding environment and medical staff when the urine is collected, which is not hygienic. Therefore, a urine storage bag in which a material that gels by absorbing urine is arranged inside the urine storage bag and the material absorbs urine and gels at least by the time of disposal has been studied.
 特許文献1には、尿を吸収してゲル化する粉末を内部に配置した容器が記載されている。図15には、このような容器の例として、2枚の透明の非透水性シート52,54を外周でシールし、尿を吸収してゲル化する粉末のゲル化材22を内部に配置した蓄尿バッグ700を示した。 Patent Document 1 describes a container in which a powder that absorbs urine and gels is placed inside. In FIG. 15, as an example of such a container, two transparent water- impermeable sheets 52 and 54 are sealed at the outer periphery, and a powdered gelling material 22 that gels by absorbing urine is disposed inside. A urine storage bag 700 is shown.
特開2003-125975号公報JP 2003-125975 A
 しかしながら、図15に示す従来の蓄尿バッグ700に尿を流入させた場合、粉末が尿を吸収してゲル化する際にゲル内に気泡が残留したり、ゲル化できない尿が残存したり、蓄尿バッグ内で局所的にゲル化する部分とゲル化しない部分とが分離してダマができたりする結果、ゲルが不均一に形成されるという問題があることが判明した。ここでいう「ダマ」とは、ゲルの内部にゲル化できずに残留した粉末の集合体のことである。不均一なゲル化が起こると、ゲル化した状態での尿の量の計測や性状の観測を視覚的に高精度に行うことができず、尿を吸収してゲル化する材料を用いた蓄尿バッグの実用化の障害となっている。また、この問題は尿に限らず、腹水/胸水、胆汁、消化管液、術野浸出液、脳脊髄液、のドレナージ、腹膜透析液などの一般的な生体排液を収容する容器にも同様に当てはまる。 However, when urine is caused to flow into the conventional urine storage bag 700 shown in FIG. 15, when the powder absorbs urine and gels, bubbles remain in the gel, urine that cannot be gelated remains, urine storage It has been found that there is a problem that the gel is formed unevenly as a result of the local gelation and the non-gelation in the bag separating and creating lumps. The “dama” here refers to an aggregate of powders that remain in the gel without remaining gelled. If non-uniform gelation occurs, the amount of urine in the gelled state and the observation of properties cannot be measured visually with high accuracy, and urine storage using a material that gels by absorbing urine It is an obstacle to practical use of bags. This problem is not limited to urine, but also to containers that contain general biological drainage such as ascites / pleural effusion, bile, gastrointestinal fluid, surgical exudate, cerebrospinal fluid drainage, and peritoneal dialysis fluid. apply.
 そこで本発明は、上記課題に鑑み、気泡やダマの残留およびゲル化しない生体排液の残存を抑制することで、生体排液を均一なゲルの状態で収容することが可能な容器を提供することを目的とする。 Therefore, in view of the above problems, the present invention provides a container that can contain biological waste liquid in a uniform gel state by suppressing the remaining of bubbles and lumps and the residual biological waste liquid that does not gel.

 (第1の実施形態)
 図1~3を参照して、本発明の第1の実施形態による容器(蓄尿バッグ)100を説明する。容器100は、尿をゲルの状態で収容するための容器である。容器100は、図1および図2に示すように、2枚の透明の非透水性シートからなる外装シート52,54を外周でシールし、内部空間を形成した容器本体50を有する蓄尿バッグである。シールの形成方法は外装シート52,54を液密に固着させることができれば限定されない。例えば、外装シート52,54を熱可塑性樹脂製フィルムとすれば、外装シート52,54の周縁部同士を加熱、押圧することにより、熱シールを形成することができる。あるいは、外装シート52,54の周縁部同士を接着剤により接着させてもよい。
(First embodiment)
A container (urine storage bag) 100 according to a first embodiment of the present invention will be described with reference to FIGS. The container 100 is a container for storing urine in a gel state. As shown in FIGS. 1 and 2, the container 100 is a urine storage bag having a container body 50 in which outer sheets 52 and 54 made of two transparent water-impermeable sheets are sealed at the outer periphery to form an internal space. . The method for forming the seal is not limited as long as the exterior sheets 52 and 54 can be fixed in a liquid-tight manner. For example, if the exterior sheets 52 and 54 are made of a thermoplastic resin film, a heat seal can be formed by heating and pressing the peripheral portions of the exterior sheets 52 and 54. Or you may adhere | attach the peripheral parts of the exterior sheets 52 and 54 with an adhesive agent.
 容器100は、尿を流入させ、少なくとも一時的に貯留するための第1室10と、尿を吸収するとゲル化する材料であるゲル化材22A,22Bが配設された第2室20A,20Bと、第1室10と第2室20A,20Bとを仕切る隔壁30A,30Bと、を容器内部に有する。 The container 100 allows the urine to flow in, and at least temporarily stores the first chamber 10 and the second chambers 20A and 20B in which gelling materials 22A and 22B, which are materials that gel when the urine is absorbed, are disposed. And partition walls 30A and 30B for partitioning the first chamber 10 and the second chambers 20A and 20B inside the container.
 図1に示すように、外装シート52,54を周縁部の一部(具体的には、容器の上部中央部分)はシールせず、容器内部が容器外部と連通した状態とする。そして、外装シート52,54の容器上部中央部分から容器の下方向に向けて2本の略平行なシール部分を形成することによって、図1および図2(A)に示すような導尿路56を形成する。導尿路56の入り口から容器内部に尿を流入させることができる。導尿路56を形成するためのシール部分は、容器下部のシール部分までは到達しておらず、そのため、導尿路56は第1室10と連通しており、導尿路56を介して第1室10へと尿を流入させることができる。なお、本明細書において「容器の上下方向」は、容器の通常使用状態における鉛直方向と一致するものとする。すなわち、図1~3では、紙面上側が容器100の上部、紙面下側が容器100の下部となり、これは他の実施形態でも同様である。 As shown in FIG. 1, the outer sheets 52 and 54 are not sealed at the periphery (specifically, the upper center portion of the container), and the interior of the container is in communication with the outside of the container. Then, by forming two substantially parallel seal portions from the container upper central portion of the outer sheets 52 and 54 toward the lower direction of the container, the urinary channel 56 as shown in FIGS. 1 and 2A. Form. Urine can flow into the container from the entrance of the urinary channel 56. The seal portion for forming the urinary tract 56 does not reach the seal portion at the lower part of the container. Therefore, the urinary tract 56 communicates with the first chamber 10 and is connected via the urinary tract 56. Urine can flow into the first chamber 10. In the present specification, the “vertical direction of the container” is the same as the vertical direction in the normal use state of the container. That is, in FIGS. 1 to 3, the upper side of the paper is the upper part of the container 100, and the lower side of the paper is the lower part of the container 100. This is the same in other embodiments.
 また、図1および図2(B)に示すように、外装シート52,54の容器内部側面間には隔壁30A,30Bが設けられ、これにより容器内部は第1室10と第2室20A,20Bとに区画される。本実施形態では、外装シート42,44からなる容器本体50の内面同士を接着させて形成した導尿路56が容器中央に延びているため、2つの第2室20A,20Bが形成される。また、第1室10が第2室20の下方に位置するように隔壁30A,30Bを配置したので、隔壁30A,30Bはゲル化材22A,22Bをそれぞれ支持する。 Moreover, as shown in FIG. 1 and FIG. 2 (B), partition walls 30A and 30B are provided between the container inner side surfaces of the exterior sheets 52 and 54, and thereby the container interior includes the first chamber 10 and the second chamber 20A, It is divided into 20B. In this embodiment, since the urinary channel 56 formed by adhering the inner surfaces of the container body 50 made of the exterior sheets 42 and 44 extends to the center of the container, two second chambers 20A and 20B are formed. Further, since the partition walls 30A and 30B are arranged so that the first chamber 10 is positioned below the second chamber 20, the partition walls 30A and 30B support the gelling materials 22A and 22B, respectively.
 なお、導尿路56は、第1室10へと尿を流入させることができれば本実施形態のものに限られない。例えば、チューブを容器内部または容器外部から第1室10に連通させるようにしてもよい。あるいは、容器としては導尿路を設けず、単に容器本体50の第1室部分に導尿口を設け、容器外部から当該導尿口を介して直接第1室10に尿を流入させるものでもよい。 Note that the urinary channel 56 is not limited to this embodiment as long as urine can flow into the first chamber 10. For example, the tube may be communicated with the first chamber 10 from inside or outside the container. Alternatively, as a container, a urinary tract is not provided, but a urine inlet is simply provided in the first chamber portion of the container body 50, and urine flows directly into the first chamber 10 from the outside of the container through the urine inlet. Good.
 ここで、この容器100の特徴的構成は、図1および図2(B)に示すように、ゲル化材22A,22Bの支持部である隔壁30A,30Bが、ゲル化材22A,22Bを通過させず、尿を第1室10から第2室20へと通過させることが可能な透液部からなることである。このため、第2室20A,20B中のゲル化材22A,22Bと第1室10から隔壁30A,30Bを通過した尿とが接触できる。 Here, as shown in FIG. 1 and FIG. 2 (B), the characteristic configuration of the container 100 is that the partition walls 30A and 30B, which are the support portions of the gelling materials 22A and 22B, pass through the gelling materials 22A and 22B. The urine is made of a liquid permeable portion that can pass from the first chamber 10 to the second chamber 20. For this reason, the gelling materials 22A and 22B in the second chambers 20A and 20B can come into contact with the urine that has passed through the partition walls 30A and 30B from the first chamber 10.
 このような構成を採用したことの技術的意義を、容器100の使用過程とともに説明する。 The technical significance of adopting such a configuration will be described together with the process of using the container 100.
 本発明者らの検討によれば、図15に示す従来の蓄尿バッグ700でゲル化の際に気泡やダマが残留する理由は、尿をゲル化材22の上面から流入させることにあった。ゲル化材22の上面が尿と接触すると、ゲル化材の上面がゲルの被膜へと変化する一方、ゲルの被膜の直下に未反応のゲル化材が残存することになるのである。残存したゲル化材はゲルの被膜に遮られ、気密構造を形成し尿と接触しづらいため、均一なゲル化が進行せず、その後尿を導入し続けるとゲルの内部に気泡やダマが残留し、さらにはゲル化しない尿が残存してしまうこともある。そこで本発明者らは、ゲル化材の下部から尿を流入させることが可能な構造を検討し、本発明を完成するに至った。 According to the study by the present inventors, the reason why bubbles and lumps remain in the gelation in the conventional urine storage bag 700 shown in FIG. 15 is that urine flows from the upper surface of the gelling material 22. When the upper surface of the gelling material 22 comes into contact with urine, the upper surface of the gelling material changes to a gel film, while an unreacted gelling material remains immediately below the gel film. The remaining gelling material is blocked by the gel coating, forming an airtight structure and difficult to contact with urine, so uniform gelation does not proceed, and if urine is continued to be introduced, bubbles and lumps remain inside the gel. Furthermore, urine that does not gel may remain. Therefore, the present inventors have studied a structure that allows urine to flow from the lower part of the gelling material, and have completed the present invention.
 ここで図3により容器100の使用過程を説明する。まず、導尿路56に尿を流入させると、その尿は第1室10に流入し、一時的に貯留される。ここで、容器100では、隔壁30A,30Bは尿を通過させるので、図3(A)に示すように、第1室10が尿で満たされると、尿は隔壁30A,30Bを通過し、第2室20A,20Bへと進入する。さらに、容器100では、隔壁30A,30Bによって第2室中のゲル化材22A,22Bが支持されているので、第2室20A,20Bに進入した尿は、ゲル化材22A,22Bの最下部と接触する。よって、図3(A)のようにゲル化材22A,22Bの下部からゲル24の成長を始めることができる。さらに、第1室10に尿を流入させ続けると、第2室20A,20B内においてゲル化材のゲル化がさらに進行し、図3(B)に示すように、最終的には全てのゲル化材がゲル24となる。 Here, the process of using the container 100 will be described with reference to FIG. First, when urine flows into the urinary tract 56, the urine flows into the first chamber 10 and is temporarily stored. Here, in the container 100, since the urine passes through the partition walls 30A and 30B, as shown in FIG. 3A, when the first chamber 10 is filled with urine, the urine passes through the partition walls 30A and 30B, Enter the two rooms 20A and 20B. Furthermore, in the container 100, since the gelling materials 22A and 22B in the second chamber are supported by the partition walls 30A and 30B, the urine that has entered the second chambers 20A and 20B is at the bottom of the gelling materials 22A and 22B. Contact with. Therefore, the growth of the gel 24 can be started from the lower part of the gelling materials 22A and 22B as shown in FIG. Furthermore, if the urine continues to flow into the first chamber 10, the gelation of the gelling material further proceeds in the second chambers 20A and 20B, and finally, as shown in FIG. The chemical material becomes the gel 24.
 このように、本実施形態の容器100によれば、ゲル化材の下部から尿を流入させることができる。ここで、単にゲル化材の下部から尿を流入させるのであれば、図15に示した従来の容器700の例えば容器本体底部に導尿口を設ければよいが、これでは容器に流入させる初期の尿と接触可能なゲル化材が限定的であり、均一なゲル化は望めない。本実施形態では、容器内部に第1室10という空間を設け、その空間に尿を一時的に貯留し、その後隔壁30を通過させてゲル化することにより、ゲル化材の下側の全体に対して尿を進入させることができる。よって、本実施形態の容器100によれば、気泡やダマの残留およびゲル化しない尿の残存を抑制して尿を均一なゲルの状態で収容することができるのである。その結果、例えば図1に示した目盛りを用いて、容器外部から目視で尿量を正確に計測したり、尿の性状や色を正確に観察したりすることできる。なお、本発明は、ゲル化材と尿が接触した結果、尿の全てがゲルの状態となることには限定されず、尿の一部がゾルの状態のままでもよい。 Thus, according to the container 100 of this embodiment, urine can be allowed to flow from the lower part of the gelling material. Here, if the urine is simply allowed to flow from the lower part of the gelling material, a urine inlet may be provided, for example, at the bottom of the container main body of the conventional container 700 shown in FIG. The gelling material that can be contacted with urine is limited, and uniform gelation cannot be expected. In the present embodiment, a space called the first chamber 10 is provided inside the container, urine is temporarily stored in the space, and then gelled by passing through the partition wall 30, so that the entire lower side of the gelled material is formed. On the other hand, urine can enter. Therefore, according to the container 100 of this embodiment, urine can be accommodated in a uniform gel state by suppressing the remaining of bubbles and lumps and the remaining of urine that does not gel. As a result, for example, using the scale shown in FIG. 1, the amount of urine can be accurately measured visually from the outside of the container, and the properties and colors of urine can be accurately observed. Note that the present invention is not limited to the fact that all of the urine is in a gel state as a result of the contact between the gelling material and urine, and part of the urine may remain in the sol state.
 なお、容器100の使用末期において、図3(B)に示すような第1室10に残留した尿は、そのまま液状で第1室10内に収容してもよいが、使用者が容器本体50の第1室部分を押圧したり、容器100を逆さにしたりすれば、第2室20A,20Bへと尿を移動させることができる。このようにすれば、全ての尿をゲルの状態で収容することも可能である。 It should be noted that urine remaining in the first chamber 10 as shown in FIG. 3B at the end of use of the container 100 may be stored in the first chamber 10 as it is in the liquid state. If the first chamber portion is pressed or the container 100 is turned upside down, the urine can be moved to the second chambers 20A and 20B. In this way, it is possible to store all urine in a gel state.
 本実施形態では、図2(B)に示すように、隔壁30A,30Bを外装シート52,54の同じ高さに接続したので、隔壁は通常使用状態で水平に延在しているが、本発明はこれに限らず、隔壁を傾けてもよい。この場合、隔壁の一部でゲル化材を支持することもあり得る。この場合、隔壁のうちゲル化材を支持する部分の全部および少なくとも一部のみを、上記メッシュ構造のシートのような透液部とし、残りを通常の非透水性シートとしてもよい。本実施形態においても、均一なゲル化を阻害しない範囲で、隔壁30A,30Bの一部を非透水性シートとすることは可能である。 In this embodiment, as shown in FIG. 2 (B), the partition walls 30A and 30B are connected to the same height of the exterior sheets 52 and 54, so the partition walls extend horizontally in the normal use state. The invention is not limited to this, and the partition may be inclined. In this case, the gelling material may be supported by a part of the partition wall. In this case, all and at least a part of the partition wall supporting the gelling material may be a liquid-permeable portion such as the mesh-structured sheet, and the rest may be a normal water-impermeable sheet. Also in the present embodiment, it is possible to make part of the partition walls 30A and 30B non-permeable sheets as long as uniform gelation is not inhibited.
 第1室と第2室との位置関係は、隔壁の少なくとも一部でゲル化材を支持していれば特に限定されないが、容器の構造を簡易にする観点からは、本実施形態のように、第2室20A,20Bの下方に第1室10が位置することが好ましい。 The positional relationship between the first chamber and the second chamber is not particularly limited as long as the gelling material is supported by at least a part of the partition wall, but from the viewpoint of simplifying the structure of the container, as in the present embodiment. The first chamber 10 is preferably located below the second chambers 20A and 20B.
 第1室10、第2室20A,20Bの容積は特に限定されない。使い捨て蓄尿バッグの場合、例えば1日分の尿(一般的に1~3L)を収容できればよい。この量の尿をゲルの状態とすると、容積は1.2~3.2Lとなることから、第2室20A,20Bの合計容積は、2.0~3.5Lとすることができる。また、第1室10の容積は、10~100mLとすることが好ましい。10mL以上とすることにより、第1室10の容積を十分に確保して、均一なゲル化をより確実に行うことができるからである。また、100mL以下とすることにより、液状のまま第1室10内に残留する尿を最小限とすることができる。この観点から、本実施形態の場合、第1室10の高さは5~20mmの範囲内とすることができる。 The volume of the first chamber 10 and the second chambers 20A and 20B is not particularly limited. In the case of a disposable urine storage bag, for example, it is only necessary to accommodate one day's worth of urine (generally 1 to 3 L). When this amount of urine is in a gel state, the volume is 1.2 to 3.2 L, so the total volume of the second chambers 20A and 20B can be 2.0 to 3.5 L. The volume of the first chamber 10 is preferably 10 to 100 mL. This is because by setting the volume to 10 mL or more, a sufficient volume of the first chamber 10 can be secured, and uniform gelation can be more reliably performed. Moreover, the urine which remains in the 1st chamber 10 with a liquid state can be minimized by setting it as 100 mL or less. From this viewpoint, in the case of the present embodiment, the height of the first chamber 10 can be in the range of 5 to 20 mm.
 ゲル化材22は公知のものを用いることができ、例えば合成ポリマーとしては、ポリアクリル酸系樹脂、ポリエチレンオキシド系樹脂、無水マレイン酸系樹脂、ポリスルホン酸系樹脂、ポリアクリルアミド系樹脂、ポリビニルアルコール系樹脂などの材料やその組み合わせ、天然物由来ポリマーとしては、ポリアスパラギン酸系、ポリグルタミン酸系、ポリアルギン酸系、デンプン系、セルロース系、プルラン系、デキストラン系、デキストリン系、その他多糖類の架橋物および、その組み合わせを用いることができる。また、増粘多糖類を始めとする各種増粘材やモンモリロナイト等の粘土鉱物を用いることも可能である。 As the gelling material 22, known materials can be used. For example, as a synthetic polymer, polyacrylic acid resin, polyethylene oxide resin, maleic anhydride resin, polysulfonic acid resin, polyacrylamide resin, polyvinyl alcohol resin can be used. Materials such as resins, combinations thereof, and polymers derived from natural products include polyaspartic acid-based, polyglutamic acid-based, polyalginic acid-based, starch-based, cellulose-based, pullulan-based, dextran-based, dextrin-based, and other polysaccharide cross-linked products. , Combinations thereof can be used. It is also possible to use various thickening materials such as thickening polysaccharides and clay minerals such as montmorillonite.
 ゲル化材22はまた、上記材料を粉末状としたものを用いることができ、その場合、平均粒径は0.1mm~4mmが好ましい。特に0.2mm~2mmがより好ましい。0.1mm未満の場合、尿を吸収した時に表面で凝固して、それ以上の尿の吸収を阻害し、4mm超えの場合、尿の吸収効率が悪くなるおそれがあるからである。ゲル化材には単一の粒径を用いても構わないが、異なった粒径のものを組み合わせることもできる。なお、ここでいう「平均粒径」とは、レーザー回折・散乱法によって求めた粒度分布における積算値50%での粒径を意味する。 As the gelling material 22, a material obtained by powdering the above material can be used. In this case, the average particle size is preferably 0.1 mm to 4 mm. In particular, 0.2 mm to 2 mm is more preferable. If it is less than 0.1 mm, it will coagulate on the surface when urine is absorbed, impairing further urine absorption, and if it exceeds 4 mm, the urine absorption efficiency may deteriorate. A single particle diameter may be used for the gelling material, but those having different particle diameters may be combined. Here, the “average particle size” means the particle size at an integrated value of 50% in the particle size distribution obtained by the laser diffraction / scattering method.
 ここで、ゲル化材が尿を吸収してゲルとなった後、当該ゲルは吸水余力がなくなるまでは尿を吸収し、膨張を続け、吸水余力がなくなると尿を吸収しなくなる。本実施形態では、図3(A)に示すゲルのうち下部のゲルが上部のゲルより先に吸水余力がなくなり、そうすると、下部のゲルはそれ以上尿を吸収しない。このとき、ゲル化材22A,22Bが、吸水余力がなくなっても尿を通過させられる粒子径(粉末の粒子径)としておけば、下部のゲルに吸水余力がなくなっても、ゲルは尿を通過させて、吸水余力の残っている上部のゲルまたは未だ尿と接触していないゲル化材へと尿を供給することができる。 Here, after the gelling material absorbs urine to form a gel, the gel absorbs urine until there is no more water absorption capacity, and continues to expand, and when there is no more water absorption capacity, it does not absorb urine. In this embodiment, the lower gel of the gel shown in FIG. 3A has no water absorption capacity before the upper gel, and the lower gel does not absorb urine any more. At this time, if the gelling materials 22A and 22B have a particle diameter (powder particle diameter) that allows urine to pass through even if there is no water absorption capacity, the gel passes through urine even if there is no water absorption capacity in the lower gel. Thus, the urine can be supplied to the upper gel where the water absorption capacity remains or the gelling material not yet in contact with the urine.
 例えば、ゲル化材の粒径は大きい方が、吸水拡張後にゲル粒子間に隙間を生じやすく、尿を透過させる構造を形成しやすい。具体的には粒径が0.1mm以上のゲル化材、あるいは、完全吸水状態にてゲル粒子が10mm以下となるようなゲル化材が好ましい。さらに、粒径が0.5mm以上のゲル化材、あるいは、完全吸水状態にてゲル粒子が5mm以下となるようなゲル化材がより好ましい。また、粒径が小さいゲル化材と粒径が大きいゲル化材とを組み合わせることで、ゲル中での尿の透過性は調整可能である。 For example, the larger the particle size of the gelling material, the easier it is to form gaps between the gel particles after water absorption expansion, and it is easier to form a structure that allows urine to permeate. Specifically, a gelling material having a particle size of 0.1 mm or more, or a gelling material having gel particles of 10 mm or less in a completely water-absorbing state is preferable. Furthermore, a gelling material having a particle size of 0.5 mm or more, or a gelling material having gel particles of 5 mm or less in a completely water-absorbing state is more preferable. Moreover, the permeability | transmittance of urine in a gel can be adjusted by combining a gelling material with a small particle size, and a gelling material with a large particle size.
 なおここで、ゲル化材22として、上述した材料を粉末のまま用いる場合は、図示は省略するが、尿が浸透可能な透水性のラッピング部材で包み込んでもよい。このラッピング部材には、例えば、ゲル化材22の粒径より小さな孔を有するメッシュシートであって、ポリエチレン、ポリプロピレン、ポリブタジエン、ポリスチレン、エチレン-酢酸ビニル重合体の様なポリオレフィン、オレフィン系エラストマー、スチレン系エラストマー等の各種熱可塑性エラストマー、ポリウレタンあるいは、これらを任意に組合せたもの(ブレンド樹脂、ポリマーアロイ、積層体等)からなるメッシュシート、または、不織布もしくは織布その他の布材等を用いることができる。そして、使用する樹脂材料は、高圧蒸気滅菌(オートクレーブ滅菌)に耐えられる耐熱性、耐水性、あるいは、γ線滅菌、EB滅菌に耐えられる性質を有していることが好ましい。 Here, when the above-described material is used as the gelling material 22 in the form of powder, illustration is omitted, but it may be wrapped with a water-permeable wrapping member that allows urine to permeate. This wrapping member is, for example, a mesh sheet having pores smaller than the particle size of the gelling material 22, such as polyethylene, polypropylene, polybutadiene, polystyrene, polyolefin such as ethylene-vinyl acetate polymer, olefin elastomer, styrene. It is possible to use various thermoplastic elastomers such as elastomers, polyurethane, mesh sheets made of any combination of these (blend resin, polymer alloy, laminate, etc.), nonwoven fabrics, woven fabrics and other cloth materials it can. The resin material to be used preferably has heat resistance and water resistance that can withstand high-pressure steam sterilization (autoclave sterilization) or a property that can withstand γ-ray sterilization and EB sterilization.
 さらに、ラッピング部材を水溶性材料で形成することもできる。これにより、尿が流入する最初の段階では、粉末状のゲル化材22がラッピング部材内に収納され、その後、水溶性のラッピング部材が尿と接触して溶け出すことで、粉末状のゲル化材22がラッピング部材から放出されるような構成としてもよい。これにより、尿が最初に流入する際に粉末状のゲル化材22が容器100内で偏在するのを防止することができる。 Furthermore, the wrapping member can be formed of a water-soluble material. Thereby, at the first stage where urine flows, the powdery gelling material 22 is accommodated in the wrapping member, and then the water-soluble wrapping member melts in contact with the urine, so that the powdery gelation is performed. The material 22 may be configured to be released from the wrapping member. Thereby, it is possible to prevent the powdered gelling material 22 from being unevenly distributed in the container 100 when urine first flows.
 ゲル化材22はまた、上記の粉末を加工してなる成形体としてもよく、(i)粉末状の材料を焼結してなるシート状成形体、(ii)粉体に水を加えて、膨潤・ゲル化させたものを乾燥してなるシート状成形体、あるいは、(iii)粉末状の材料を所定の有機溶媒に溶かした後に、これを乾燥してなるフィルム状成形体、などが挙げられる。また、パルプ等の線維素材に対して、これらゲル化材を混合したシート状の材料を用いることも可能である。このように、ゲル化材が成形体であると、尿が最初に流入する際に、粉末状の材料が容器100内で偏在するのを防止することができる。また、尿が最初に流入する段階では、粉末状の材料が成形体となっており、その後、ゲル化が進行すると同時に粉末状に分解するように構成されていてもよい。 The gelling material 22 may also be a molded body obtained by processing the above powder, (i) a sheet-shaped molded body obtained by sintering a powdery material, and (ii) adding water to the powder, Examples include a sheet-like molded body obtained by drying a swollen / gelled product, or (iii) a film-like molded body obtained by dissolving a powdery material in a predetermined organic solvent and then drying it. It is done. Moreover, it is also possible to use the sheet-like material which mixed these gelling materials with respect to fiber raw materials, such as a pulp. Thus, when the gelling material is a molded body, it is possible to prevent the powdered material from being unevenly distributed in the container 100 when urine first flows in. Moreover, at the stage where urine first flows in, the powdery material may be formed into a molded body, and then may be configured to decompose into powder at the same time as gelation proceeds.

 (第1の実施形態の変形例1)
 図4を参照して、第1の実施形態の変形例にかかる容器(蓄尿バッグ)200を説明する。本変形例は、外装シート54の容器内部側面に隙間としての細溝を設けたこと以外は第1の実施形態の容器100と同様であるため、第1の実施形態と異なる点のみ説明する。
(Modification 1 of the first embodiment)
With reference to FIG. 4, the container (urine storage bag) 200 concerning the modification of 1st Embodiment is demonstrated. Since this modification is the same as the container 100 of the first embodiment except that a narrow groove as a gap is provided on the inner side surface of the container of the exterior sheet 54, only differences from the first embodiment will be described.
 容器200は、外装シート54に、容器上下方向に延在する2本の溝である流路60A,60Bおよび容器左右方向に延在する溝である5本の溝である流路62A~62Eを有する。これにより、容器200では、第2室中で隔壁側から上方向にゲルが膨潤した後でも、これらの流路を尿が通過することで、第1室10中の尿が第2室20A,20Bの上方向に移動することができる。よって、下部のゲルに吸水余力がなくなっても、吸水余力の残っている上部のゲルまたは未だ尿と接触していないゲル化材へと尿を供給することができる。 In the container 200, channels 60A and 60B that are two grooves extending in the vertical direction of the container and channels 62A to 62E that are five grooves that are extended in the horizontal direction of the container are provided on the exterior sheet 54. Have. Thereby, in the container 200, even after the gel swells upward from the partition wall side in the second chamber, the urine in the first chamber 10 passes through these flow paths so that the urine in the first chamber 10 becomes the second chamber 20A, 20B can be moved upward. Therefore, even if the lower gel has no water absorption capacity, urine can be supplied to the upper gel where the water absorption capacity remains or the gelling material that has not yet contacted the urine.
 流路表面は、流路内部にゲルが侵入しないように高分子メッシュなどでカバーすることができる。また、尿を円滑に移動させる観点から、流路の深さは0.5mm以上とし、幅は3mm以上とすることが好ましい。 The surface of the flow path can be covered with a polymer mesh or the like so that the gel does not enter the flow path. In addition, from the viewpoint of smoothly moving urine, the depth of the channel is preferably 0.5 mm or more and the width is 3 mm or more.
 流路を設ける位置は特に限定されないが、図4(A)に示すように、一部の流路は第1室10にまでわたって延在することが好ましい。また、外装シート52,54の両方に流路を設けてもよい。流路の延在態様としては、流路60A,60Bのような容器上下方向に延在する流路(延在方向に容器上下方向の成分がある流路)によって、容器上方向へと尿が移動できるが、さらに流路62A~62Eのような容器左右方向に延在する流路(延在方向に容器左右方向の成分がある流路)があると、より均一なゲル化を実現することができるため好ましい。 The position where the flow path is provided is not particularly limited, but it is preferable that a part of the flow path extends to the first chamber 10 as shown in FIG. Moreover, you may provide a flow path in both the exterior sheets 52 and 54. FIG. As an extension mode of the flow path, urine flows upward in the container by a flow path extending in the vertical direction of the container such as the flow paths 60A and 60B (a flow path having components in the vertical direction of the container in the extending direction). Even if there is a flow path extending in the left-right direction of the container (flow path having a component in the left-right direction of the container in the extending direction) such as flow paths 62A to 62E, it can achieve more uniform gelation. Is preferable.
 隙間は本実施形態のような直線または曲線状の溝でなくてもよい。例えば、外装シート表面に、膨張したゲルが侵入しない程度の微小な凹部を多数設け、これらの凹部が互いに連通するようにしておけば、これらの凹部を尿が移動することで、吸水余力の残っている上部のゲルまたは未だ尿と接触していないゲル化材へと尿を供給することができる。 The gap may not be a straight or curved groove as in this embodiment. For example, if the surface of the exterior sheet is provided with a large number of minute recesses that do not allow the expanded gel to enter, and these recesses communicate with each other, the urine moves through these recesses, so that the remaining water absorption capacity remains. The urine can be fed to the upper gel or the gelling material that is not yet in contact with the urine.
 また、外装シート54に直接流路を設けるのではなく、メッシュシートを外装シートとゲル化材との間に配置する方法をとっても構わない。この場合においてメッシュシートは、ゲルが透過せず尿が拡散できる隙間を、外装シートとゲルとの間に形成できることが必要条件となる。例えば、目の細かいメッシュをゲル化材側に、目が粗く厚みのあるメッシュを外装シート内壁側に設置することで尿が拡散できる隙間を形成することが出来る。このように、ゲル化材へ尿を供給するための隙間をバッグ内部に構造的に形成することが重要であり、隙間は高分子メッシュ、吸水紙、バッグ内壁に形成された溝などを利用することが可能である。 Further, instead of providing a flow path directly in the exterior sheet 54, a method of arranging a mesh sheet between the exterior sheet and the gelling material may be used. In this case, the mesh sheet is required to be able to form a gap between the exterior sheet and the gel so that the urine can diffuse without allowing the gel to permeate. For example, a gap in which urine can be diffused can be formed by installing a fine mesh on the gelling material side and a coarse mesh with a thick mesh on the inner wall side of the exterior sheet. As described above, it is important to structurally form a gap for supplying urine to the gelling material inside the bag, and the gap uses a polymer mesh, water absorbent paper, a groove formed on the inner wall of the bag, and the like. It is possible.
 (第1の実施形態の変形例2)
 図5を参照して、第1の実施形態の他の変形例にかかる容器(蓄尿バッグ)300を説明する。本変形例は、外装シート54の容器内部側面に吸水シート56を設けたこと以外は第1の実施形態の容器100と同様であるため、第1の実施形態と異なる点のみ説明する。
(Modification 2 of the first embodiment)
With reference to FIG. 5, the container (urine storage bag) 300 concerning the other modification of 1st Embodiment is demonstrated. Since this modified example is the same as the container 100 of the first embodiment except that the water absorbing sheet 56 is provided on the container inner side surface of the exterior sheet 54, only differences from the first embodiment will be described.
 容器300は、外装シート54の容器内部側面に吸水シート56を有する。容器300では、第2室中で隔壁側から上方向にゲルが膨潤した後でも、吸水シート56によって、第1室10中の尿を第2室20A,20Bの上方向に吸い上げることができる。よって、下部のゲルに吸水余力がなくなっても、吸水余力の残っている上部のゲルまたは未だ尿と接触していないゲル化材へと尿を供給することができる。吸水シート56は、例えば不織布または織布その他の布材とすることができる。 The container 300 has a water absorbing sheet 56 on the inner surface of the exterior sheet 54. In the container 300, even after the gel swells upward from the partition wall side in the second chamber, the urine in the first chamber 10 can be sucked upward in the second chambers 20A and 20B by the water absorbing sheet 56. Therefore, even if the lower gel has no water absorption capacity, urine can be supplied to the upper gel where the water absorption capacity remains or the gelling material that has not yet contacted the urine. The water absorbing sheet 56 can be made of, for example, a non-woven fabric, a woven fabric, or other cloth material.
 吸水シート56が、第1室および第2室にわたって位置すると、第1室10の尿を確実に吸い上げることができるので、より好ましい。また、均一なゲル化を確実に行う観点から、図5に示すように、吸水シート56は、高さ方向にはゲルが成長する最高位置まで配設し、幅方向にはゲル化材が存在する範囲をカバーするように配設することが好ましい。また、外装シート52,54の両方に吸水シートを設けてもよい。また、吸水シートは必ずしも外装シートに固定する必要はないことは勿論であり、外装表面に凸部を設けることで間隙を形成する構造としても良い。 It is more preferable that the water absorbing sheet 56 is positioned over the first chamber and the second chamber because the urine in the first chamber 10 can be sucked up reliably. Further, from the viewpoint of ensuring uniform gelation, as shown in FIG. 5, the water absorbent sheet 56 is disposed up to the highest position where the gel grows in the height direction, and there is a gelling material in the width direction. It is preferable to arrange so as to cover the range. Moreover, you may provide a water absorbing sheet in both the exterior sheets 52 and 54. In addition, it is needless to say that the water absorbent sheet is not necessarily fixed to the exterior sheet, and a structure may be adopted in which a gap is formed by providing a convex portion on the exterior surface.
 (第2の実施形態)
 図6~9を参照して、本発明の第2の実施形態による容器(蓄尿バッグ)400を説明する。容器400は、尿をゲルの状態で収納するための可撓性容器である。容器400は、図6(A),(B)に示すように、2枚の透明且つ可撓性の非透水性シートからなる外装シート52,54を外周でシールし、内部空間を形成した蓄尿バッグである。容器400は、尿を流入させ、少なくとも一時的に貯留するための第1室10と、尿を吸収するとゲル化する材料である粉末状のゲル化材22が配設された第2室20と、第1室10と第2室20とを仕切る隔壁40と、を有する。すなわち、図6(B)に示すように、導尿口58は第1室10と連通しており、導尿口58から第1室10へと尿を流入させることができる。なお、第1室10への尿の供給位置は、特に限定はなく、例えば、第1室10の下方乃至側方からであってもよい。
(Second Embodiment)
A container (urine storage bag) 400 according to a second embodiment of the present invention will be described with reference to FIGS. The container 400 is a flexible container for storing urine in a gel state. As shown in FIGS. 6 (A) and 6 (B), the container 400 seals outer sheets 52 and 54 made of two transparent and flexible water-impermeable sheets on the outer periphery to form a urine storage in which an internal space is formed. It is a bag. The container 400 has a first chamber 10 for allowing urine to flow in and at least temporarily storing it, and a second chamber 20 provided with a powdered gelling material 22 that is a material that gels when urine is absorbed. And a partition wall 40 that partitions the first chamber 10 and the second chamber 20. That is, as shown in FIG. 6B, the urine inlet 58 communicates with the first chamber 10, and urine can flow into the first chamber 10 from the urine inlet 58. In addition, the supply position of urine to the first chamber 10 is not particularly limited, and may be, for example, from below or to the side of the first chamber 10.
 ここで、隔壁40は、容器の上下方向に延在し、かつ、ゲル化材22を通過させず、尿を第1室10から第2室20へ通過させることが可能な透液部40Aと、この透液部40Aよりも尿を通過させにくい非透液部40Bと、からなる。容器400に最初に流入する尿は、第2室20におけるゲル化材22の上面22Xよりも下部の透液部40Aを介して第1室10から第2室20へ流入するように構成されている。つまり、本実施形態では、隔壁40のうちゲル化材22の支持部の一部が透液部40Aとなっている。このため、尿がゲル化材の上面22Xからではなく、ゲル化材22の側部下方から導入される。よって、本実施形態でも、第1の実施形態と同様に、気泡やダマの残留およびゲル化しない生体排液の残存を抑制して尿を均一なゲルの状態で収容することができる。 Here, the partition wall 40 extends in the vertical direction of the container, and does not allow the gelling material 22 to pass therethrough, and allows the urine to pass from the first chamber 10 to the second chamber 20. The non-liquid permeable part 40B is more difficult to pass urine than the liquid permeable part 40A. The urine that first flows into the container 400 is configured to flow from the first chamber 10 into the second chamber 20 via the liquid-permeable portion 40A below the upper surface 22X of the gelling material 22 in the second chamber 20. Yes. That is, in this embodiment, a part of the support part of the gelling material 22 in the partition wall 40 is the liquid permeable part 40A. For this reason, urine is introduced not from the upper surface 22X of the gelling material but from below the side of the gelling material 22. Therefore, also in the present embodiment, as in the first embodiment, it is possible to suppress urine from remaining in the form of a uniform gel while suppressing the remaining of bubbles and lumps and the remaining of biological waste fluid that does not gel.
 隔壁40の詳細な構造を図6(C)により説明する。隔壁40は、透液部40Aと非透液部40Bとからなり、透液部40Aは、隔壁40の下部に配設された透液部40AXと、隔壁40の側部に配設された透液部40AYとからなる。なお、本実施形態では非透液部40Bは尿を通過させない。隔壁40の図6(C)に示す幅方向両端部410は、外装シート52,54とともにシールされている。 The detailed structure of the partition 40 will be described with reference to FIG. The partition wall 40 includes a liquid permeable portion 40A and a non-liquid permeable portion 40B. The liquid permeable portion 40A includes a liquid permeable portion 40AX disposed at a lower portion of the partition wall 40 and a permeable portion disposed at a side portion of the partition wall 40. It consists of liquid part 40AY. In the present embodiment, the non-liquid permeable portion 40B does not allow urine to pass through. Both end portions 410 in the width direction shown in FIG. 6C of the partition wall 40 are sealed together with the exterior sheets 52 and 54.
 ここで、図13に示すような、容器の上下方向に延在する隔壁90の下部のみに透液部90Aが配設された容器600との比較を検討する。この容器600も、隔壁90のうちゲル化材22の支持部の一部が透液部90Aとなっており、気泡やダマの残留およびゲル化しない尿の残存を抑制した均一なゲルを形成可能である。よって、この容器600は、本発明の第3の実施形態を構成するものである。 Here, a comparison with a container 600 in which a liquid permeable portion 90A is disposed only at the lower part of a partition wall 90 extending in the vertical direction of the container as shown in FIG. 13 will be considered. In this container 600, a part of the support part of the gelling material 22 in the partition wall 90 is a liquid permeable part 90A, and it is possible to form a uniform gel that suppresses the remaining of bubbles and lumps and the remaining urine that does not gel. It is. Therefore, this container 600 constitutes a third embodiment of the present invention.
 しかし、本発明者らの検討によれば、容器600の場合、第1室10に流入された尿が隔壁90の下側に設けられた透液部90Aを通じて第2室20に流入すると、図14に示すように、第2室20に配置されたゲル化材22が尿を吸収することにより形成されたゲル24の形状が、容器上方向に凸の形状になりやすく、ゲル化した状態(特に、ゲル化の途中の段階)での尿の量の計測を精度高く視覚的に行うことができないことが判明した。 However, according to the study by the present inventors, in the case of the container 600, when the urine that has flowed into the first chamber 10 flows into the second chamber 20 through the liquid permeable portion 90A provided on the lower side of the partition wall 90, FIG. 14, the gel 24 formed by the gelling material 22 disposed in the second chamber 20 absorbing urine is likely to be a convex shape in the upward direction of the container, and is in a gelled state ( In particular, it has been found that measurement of the amount of urine in the middle of gelation) cannot be performed visually with high accuracy.
 このように、容器600で、ゲル24の形状が容器上方向に凸の形状になりやすい理由は、図13(A)の幅方向WDにおける尿流の制御がなされていないことにあった。容器400は、両端部410がシールされており、シールされている両端部410から離間した幅方向中央部分が拡張しやすいため、第1室10における幅方向中央部分に尿が流入する隙間ができやすくなる。よって、第1室10から第2室20への尿の流量は両端部410付近よりも幅方向中央部分の方が大きくなる。その結果、中央部分において優先的にゲル化反応が進行し、ゲル24の形状が、容器上方向に凸の形状になるのである。 Thus, the reason why the shape of the gel 24 tends to be convex upward in the container 600 is that the urine flow in the width direction WD in FIG. 13A is not controlled. Since the container 400 is sealed at both ends 410 and the widthwise central part spaced from the sealed both ends 410 is easy to expand, there is a gap for urine to flow into the widthwise central part of the first chamber 10. It becomes easy. Therefore, the flow rate of urine from the first chamber 10 to the second chamber 20 is larger in the central portion in the width direction than in the vicinity of both end portions 410. As a result, the gelation reaction proceeds preferentially in the central portion, and the shape of the gel 24 becomes a convex shape upward in the container.
 そこで本発明者らは、流入初期段階ではゲル化材の下部から尿を流入させるとともに、その後は、ゲル化が中央部分と比較して遅れているゲル化材22の側部に対して、効果的に尿を流入させることが可能な構造を検討した。 Therefore, the present inventors flow urine from the lower part of the gelling material in the initial stage of inflow, and thereafter, the effect is exerted on the side part of the gelling material 22 where the gelation is delayed compared to the central part. The structure that can infuse urine was examined.
 ここで図7~9により尿の流入過程の第1の例を説明する。本実施形態の容器400によれば、第1室10と第2室20とを容器の上下方向に延在する隔壁40で区画し、第2室20にゲル化材22を配置し、隔壁40が、図6(C)に示すように、下部に配設された透液部40AXと、側部に配設された透液部40AYと、尿を通過させない非透液部40Bと、からなるように構成する。このため、容器400に最初に流入する尿は、図7に示すように、第1室10の下方向に移動し、第1室10における貯留部10Xに貯留される。そして、貯留された尿の上面が、隔壁40の下部に配設された透液部40AXの最下部に到達した段階で、透液部40AXを介して尿が第1室10から第2室20へ流入する。このように、流入初期段階ではゲル化材の下部から尿を流入させることができる。 Here, a first example of the inflow process of urine will be described with reference to FIGS. According to the container 400 of the present embodiment, the first chamber 10 and the second chamber 20 are partitioned by the partition wall 40 extending in the vertical direction of the container, and the gelling material 22 is disposed in the second chamber 20. As shown in FIG. 6 (C), the liquid-permeable portion 40AX disposed in the lower portion, the liquid-permeable portion 40AY disposed in the side portion, and the non-liquid-permeable portion 40B that does not allow urine to pass therethrough. Configure as follows. Therefore, the urine that first flows into the container 400 moves downward in the first chamber 10 and is stored in the storage unit 10X in the first chamber 10, as shown in FIG. Then, when the upper surface of the stored urine reaches the lowermost part of the liquid permeable part 40AX disposed in the lower part of the partition wall 40, the urine passes from the first chamber 10 to the second chamber 20 via the liquid permeable part 40AX. Flow into. Thus, urine can be allowed to flow from the lower part of the gelling material at the initial stage of inflow.
 ゲル化材22は、透液部40AXから尿を吸収し、ゲル化して膨張を続ける。ゲル化材22が膨張すると、図8に示すように、ゲル化材22の膨張力よりも隔壁40の形状保持力が小さいため、隔壁40はその下部から第1室10側に押し込まれ、第1室10の下部の容積が減少していき、その結果、隔壁40の一番下の透液部40AXは膨張したゲル24と外装シート52とで塞がれることにより、透液部40AXへの尿の到達が抑制される。ここで、形状保持力とは隔壁40が略平面形状を保つことが可能な力を指す。また、図8に示すように、ゲル24の上に未反応のゲル化材22が位置する。さらに、ゲル24のうち下部のゲルは吸水余力が少なくなっているが、中部・上部のゲルには吸水余力が十分残っている。この段階では、透液部40AX近傍のゲルは吸水余力が少なくなっている上に、ゲルの膨張によって第1室10の下部が潰された結果、尿は、透液部40AXの高さを超える高さまで第1室10内に貯留され、隔壁40の側部に配設された透液部40AYを介して第1室10から第2室20へ流入し始める。尿が透液部40AXのみから第2室20に流入する初期段階では、ゲル24は、容器上方向に凸の形状になるように成長している。よって、尿が透液部40AYを介して第1室10から第2室20へ流入し始めることにより、ゲル24の上面が幅方向WD(図6(A))でより平坦となってくるこのように、尿の流れを幅方向WDでコントロールして、高さが幅方向WDで均一なゲル24を形成することができる。 The gelling material 22 absorbs urine from the liquid permeable part 40AX, gels and continues to expand. When the gelling material 22 expands, as shown in FIG. 8, the shape retaining force of the partition wall 40 is smaller than the expansion force of the gelling material 22, so the partition wall 40 is pushed into the first chamber 10 side from below, As a result, the volume of the lower part of the chamber 10 is reduced, and as a result, the lower liquid-permeable part 40AX of the partition wall 40 is blocked by the expanded gel 24 and the exterior sheet 52, so that the liquid-permeable part 40AX The arrival of urine is suppressed. Here, the shape holding force refers to a force with which the partition wall 40 can maintain a substantially planar shape. As shown in FIG. 8, the unreacted gelling material 22 is positioned on the gel 24. Further, the lower gel of the gel 24 has less water absorption capacity, but the middle and upper gels still have sufficient water absorption capacity. At this stage, the gel in the vicinity of the liquid permeable portion 40AX has less water absorption capacity, and the lower portion of the first chamber 10 is crushed by the expansion of the gel. As a result, the urine exceeds the height of the liquid permeable portion 40AX. It is stored in the first chamber 10 up to a height and starts to flow from the first chamber 10 into the second chamber 20 via the liquid-permeable portion 40AY disposed on the side of the partition wall 40. In the initial stage where urine flows into the second chamber 20 only from the liquid permeable part 40AX, the gel 24 grows so as to have a convex shape in the upward direction of the container. Therefore, urine begins to flow from the first chamber 10 to the second chamber 20 through the liquid permeable portion 40AY, so that the upper surface of the gel 24 becomes flatter in the width direction WD (FIG. 6A). Thus, the flow of urine can be controlled in the width direction WD, and the gel 24 having a uniform height in the width direction WD can be formed.
 全てのゲル化材22がゲル化する頃には、図9に示すように、第1室10の大部分がゲルで潰される。そのため、最後は、第1室10から第2室20に流入する尿の大部分が、隔壁40の側部に配設された透液部40AYの上部(第1室10に貯留された尿の上面付近)を介して流入した尿となる。このとき透液部40AYの上部の高さのゲルは吸水余力を残している一方、それより下のゲルには吸水余力が少なくなっている。透液部40AYの上部の高さのゲルの吸水余力がなくなると、容器100の中でこれ以上尿をゲルの状態で保持できないため、ここまでで尿の流入を中止する。 When all the gelling materials 22 are gelled, most of the first chamber 10 is crushed with gel as shown in FIG. Therefore, at the end, most of the urine flowing into the second chamber 20 from the first chamber 10 is made up of the upper part of the liquid-permeable portion 40AY disposed on the side of the partition wall 40 (the urine stored in the first chamber 10). It becomes urine that flows in through the upper surface). At this time, the gel at the height of the upper part of the liquid-permeable portion 40AY has left the water absorption capacity, while the gel below it has less water absorption capacity. If there is no more water absorption capacity of the gel at the upper part of the liquid permeable part 40AY, the urine cannot be held in the gel state any more in the container 100, so the inflow of urine is stopped so far.
 以上説明したように、本実施形態の容器400によれば、最初に流入する尿を、隔壁40の下部に配設された透液部40AXを介してゲル化材22の下部から吸収させ、さらに、透液部40AXに尿が流入しにくくなった後は、隔壁40の側部に配設された透液部40AYを介して尿が供給される。そのため、気泡やダマの残留を抑制した均一なゲルが形成できると共に、尿の流れをコントロールして、上面が平坦なゲルを形成することができる。そのため、ゲル化した状態(特に、ゲル化の途中の段階)での尿の量の計測を精度高く視覚的に行うことができる。 As described above, according to the container 400 of the present embodiment, the urine that flows in first is absorbed from the lower part of the gelling material 22 via the liquid-permeable part 40AX disposed in the lower part of the partition wall 40, and After the urine becomes difficult to flow into the liquid permeable portion 40AX, the urine is supplied through the liquid permeable portion 40AY disposed on the side portion of the partition wall 40. Therefore, it is possible to form a uniform gel in which bubbles and lumps remain, and to control the flow of urine to form a gel having a flat upper surface. Therefore, the measurement of the amount of urine in a gelled state (particularly in the middle of gelation) can be performed visually with high accuracy.
 図7~9で示した尿の流入過程の一例では、隔壁40の側部に配設された透液部40AYから尿が第2室20に流入する際には、吸水余力を残したゲル24に尿が供給される。しかし、本発明はこれに限定されず、第2の例として、ゲル化していないゲル化材22に尿が供給されるものでもよい。この場合でも、気泡やダマの残留が抑制された均一なゲルの形成が可能となる。ただしこの場合は、例えば、透液部40AYから尿がゲル化材22に供給されて当該ゲル化材22がゲル化した後、その前の透液部40AXから供給された尿によって成長したゲルと一体化し、ゲルとゲルとの間にゲル化材22が残らないことが好ましい。 In the example of the urine inflow process shown in FIGS. 7 to 9, when the urine flows into the second chamber 20 from the liquid permeable portion 40AY disposed on the side of the partition wall 40, the gel 24 that has retained the water absorption capacity. The urine is supplied. However, the present invention is not limited to this, and as a second example, urine may be supplied to the gelled material 22 that is not gelled. Even in this case, it is possible to form a uniform gel in which the remaining of bubbles and lumps are suppressed. However, in this case, for example, after the urine is supplied from the liquid permeable portion 40AY to the gelling material 22 and the gelled material 22 is gelled, the gel grows by the urine supplied from the previous liquid permeable portion 40AX. It is preferable that the gelling material 22 is not left between the gel and the gel.
 第1室10および第2室20の容積、ゲル化材22の量、隔壁40の寸法(例えば透液部40Aおよび非透液部40Bの幅)は適宜設定して、図7~図9に示す第1の例や上述の第2の例のようにゲル化が行えるようにすればよい。例えば、既知のゲルの膨張率を考慮して第2室20の容積を決定し、ゲルの膨張速度を考慮して、第1室10の容積および隔壁40の寸法を決定することができる。また、透液部40AXの高さHは、充填するゲル化材22の高さよりも低いことが好ましい。例えば、外装シートが幅180mm×高さ250mm程度の容器の場合、隔壁40の寸法としては、隔壁40の下部に配設された透液部40AXの高さH(図6(C))を10mm~30mm、好ましくは20mm程度とし、隔壁40の側部に配設された透液部40AYの幅W(図6(C))を3mm~15mm、好ましくは5mm~10mm程度とすることができる。透液部40AXの高さHが30mmを超えると、流入初期段階の尿がゲル化材22の上方からかかってしまいゲル化材22の上面22Aにゲルの被膜が形成されてしまう可能性がある。また、隔壁40において、幅W/シート幅の値は、1/10~1/30が好ましく、1/18程度がより好ましい。さらに、隔壁40において、高さH/シート高さの値は、1/5~1/25が好ましく、1/12.5程度がより好ましい。 The volumes of the first chamber 10 and the second chamber 20, the amount of the gelling material 22, and the dimensions of the partition wall 40 (for example, the widths of the liquid permeable portion 40A and the non-liquid permeable portion 40B) are set as appropriate. What is necessary is just to enable it to gelatinize like the 1st example shown and the above-mentioned 2nd example. For example, the volume of the second chamber 20 can be determined in consideration of the known expansion rate of the gel, and the volume of the first chamber 10 and the dimensions of the partition wall 40 can be determined in consideration of the expansion rate of the gel. Moreover, it is preferable that the height H of the liquid permeable part 40AX is lower than the height of the gelling material 22 to be filled. For example, when the exterior sheet is a container having a width of about 180 mm and a height of about 250 mm, the partition wall 40 has a dimension that the height H (FIG. 6C) of the liquid-permeable portion 40AX disposed below the partition wall 40 is 10 mm. The width W (FIG. 6C) of the liquid-permeable portion 40AY disposed on the side portion of the partition wall 40 can be 3 mm to 15 mm, preferably about 5 mm to 10 mm. If the height H of the liquid permeable portion 40AX exceeds 30 mm, urine at the initial inflow stage may be applied from above the gelling material 22 and a gel film may be formed on the upper surface 22A of the gelling material 22. . In the partition wall 40, the width W / sheet width value is preferably 1/10 to 1/30, more preferably about 1/18. Further, in the partition wall 40, the value of height H / sheet height is preferably 1/5 to 1/25, and more preferably about 1 / 12.5.
 ゲル化材22および外装シート52,54の態様は、第1の実施形態と同様である。ただし、本実施形態では、外装シート52,54は可撓性シートである。 The aspects of the gelling material 22 and the exterior sheets 52 and 54 are the same as those in the first embodiment. However, in the present embodiment, the exterior sheets 52 and 54 are flexible sheets.
 隔壁40の透液部40Aとしては、ゲル化材22は通過させず尿を通過させる構造であれば特に限定されず、メッシュ構造のシートなど、第1の実施形態の隔壁30と同様の構造とすることができる。この構造により、ゲル化材22が透液部40Aにせき止められ、第1室10に流出することを抑制することができる。 The liquid permeable portion 40A of the partition wall 40 is not particularly limited as long as it does not allow the gelling material 22 to pass through but allows urine to pass through, and has the same structure as the partition wall 30 of the first embodiment, such as a mesh structure sheet. can do. With this structure, it is possible to prevent the gelling material 22 from being blocked by the liquid permeable portion 40 </ b> A and flowing out into the first chamber 10.
 通常、メッシュ構造のシートは、所定の圧力がかかったときのみに、尿を通す(尿がしみ出す)程度のものであり、尿と接触して濡れているだけでは尿を透過させないものが好ましい。 Usually, the mesh-structured sheet is such that only when a predetermined pressure is applied, urine passes (urine oozes out), and a sheet that does not allow urine permeation only by being in contact with urine and being wet is preferable. .
 例えば、透液部40AXに紙等の目が非常に細かいメッシュ構造を用いることにより粉末状のゲル化材22の上面のみが吸水してゲルの被膜を形成してしまうリスクを低減することができる。また、透液部40AYに紙等の目が非常に細かいメッシュ構造を用いることにより、透液部40AYの幅W(図6(C))を大きくすることができる。 For example, it is possible to reduce the risk that only the upper surface of the powdered gelling material 22 absorbs water and forms a gel film by using a mesh structure with very fine eyes such as paper for the liquid permeable portion 40AX. . Moreover, the width W (FIG. 6C) of the liquid-permeable portion 40AY can be increased by using a mesh structure with very fine eyes such as paper for the liquid-permeable portion 40AY.
 隔壁40の非透液部40Bとしては、例えば外装シート52,54と同様の材料からなるシートを用いることができる。 As the non-liquid-permeable portion 40B of the partition wall 40, for example, a sheet made of the same material as the exterior sheets 52 and 54 can be used.
 透液部40AXと、透液部40AYと、非透液部40Bとからなる隔壁40は、例えば、(I)(i)メッシュ構造の透水性フィルムと、(ii)該透水性フィルムよりも大きさ(高さおよび幅)が小さい非透水性シートと、を熱融着乃至接着などにより貼り合わせることや、(II)1枚の非透水性シートの下部および側部に微細な小孔を多数あけること、などにより作製することができる。なお、透水性フィルムとしては、例えば、微細な小孔を多数あけた高分子フィルム(例えば外装シートと同様の材料)を使用することができる。また、非透水性フィルムとしては、例えば外装シートと同様の材料を使用することができる。 The partition 40 including the liquid permeable portion 40AX, the liquid permeable portion 40AY, and the non-liquid permeable portion 40B includes, for example, (I) (i) a water permeable film having a mesh structure, and (ii) larger than the water permeable film. Bonding a non-water-permeable sheet having a small height (height and width) by heat-sealing or bonding, or (II) many fine holes on the bottom and side of one non-water-permeable sheet It can be produced by opening. In addition, as a water-permeable film, the polymer film (For example, the material similar to an exterior sheet | seat) which opened many fine pores can be used, for example. Moreover, as a water-impermeable film, the same material as an exterior sheet can be used, for example.
 ただし、本発明はこれに限定されず、例えば、非透水性フィルムを容器内部の下部に隙間ができるように配設し、さらにこの非透水性フィルムに沿ってメッシュ構造の透水性フィルムを容器内部の上端から下端まで配設する2層構造の隔壁としてもよい。 However, the present invention is not limited to this. For example, the water-impermeable film is disposed so that a gap is formed in the lower part inside the container, and the water-permeable film having a mesh structure is disposed along the water-impermeable film. It is good also as a 2 layer structure partition arrange | positioned from the upper end to the lower end.
 また、図6(C)では、透液部40AXと透液部40AYとが連続的に配設されている例を示したが、本発明はこれに限定されない。例えば、図10に示すように、透液部41AXと透液部41AYとが断続的に配設されていてもよい。つまり、透液部41AXと透液部41AYとの間に部分的に非透液部Gを設けてもよい。これにより、例えば、容器400に100~200mL程度の多量の尿が一度に流入し、ゲル化材22の吸水速度に対して容器400への尿の流入速度が多く、尿の水位が一気に上昇した場合であっても、隔壁41の側部に配設された透液部41AYを介して尿が第2室20に流入するタイミングを遅らせることができ、ゲル化材22の上から尿が供給されるのを防ぐことができる。 6C shows an example in which the liquid-permeable portion 40AX and the liquid-permeable portion 40AY are continuously disposed, but the present invention is not limited to this. For example, as shown in FIG. 10, the liquid-permeable part 41AX and the liquid-permeable part 41AY may be arrange | positioned intermittently. That is, the non-liquid-permeable part G may be partially provided between the liquid-permeable part 41AX and the liquid-permeable part 41AY. Thereby, for example, a large amount of about 100 to 200 mL of urine flows into the container 400 at a time, the inflow speed of the urine into the container 400 is higher than the water absorption speed of the gelling material 22, and the water level of the urine rises at a stretch. Even in this case, the timing at which urine flows into the second chamber 20 via the liquid-permeable portion 41AY disposed on the side of the partition wall 41 can be delayed, and urine is supplied from above the gelling material 22. Can be prevented.
 透液部41AXと透液部41AYとの間に形成された非透液部Gの長さDとしては、外装シートの幅が180mmである場合、20mm~40mmであることが好ましい。 The length D of the non-liquid-permeable part G formed between the liquid-permeable part 41AX and the liquid-permeable part 41AY is preferably 20 mm to 40 mm when the width of the exterior sheet is 180 mm.
 なお、図10に示される隔壁41は、例えば、(i)非透液部41Bを形成するT字型ポリプロピレンシートと、(ii)隔壁41と同じ大きさの、紙、プラスチックメッシュ、または不織布等と、を熱融着乃至接着等により、貼り合わせることにより、作製することができる。ここで、不織布にポリプロピレンが含まれている場合は、該不織布とT字型ポリプロピレンシートとを熱シール等により貼り合わせることができる。 The partition 41 shown in FIG. 10 includes, for example, (i) a T-shaped polypropylene sheet that forms the liquid-impermeable portion 41B, and (ii) paper, plastic mesh, or non-woven fabric having the same size as the partition 41. Are bonded together by heat fusion or adhesion. Here, when polypropylene is included in the nonwoven fabric, the nonwoven fabric and the T-shaped polypropylene sheet can be bonded together by heat sealing or the like.
 また、図6(C)では、透液部40AXの高さHが一定である例を示したが、本発明はこれに限定されない。図11に示すように、隔壁42の下部に配設された透液部42AXの高さが、隔壁42の幅方向両端部410から幅方向中央部分に向かって漸減するようにしてもよい。これにより、尿が流入する初期の段階から上面が平坦なゲルを形成することができる。 6C shows an example in which the height H of the liquid permeable portion 40AX is constant, the present invention is not limited to this. As shown in FIG. 11, the height of the liquid permeable portion 42AX disposed in the lower part of the partition wall 42 may gradually decrease from the width direction both ends 410 of the partition wall 42 toward the center portion in the width direction. Thereby, a gel with a flat upper surface can be formed from the initial stage where urine flows.
 また、図6(C)では、隔壁40の最下部が透液部40AXである例を示したが、本発明はこれに限定されず、最下部が非透液部40Bであってもよい。この場合、全てのゲル化材をゲル化する観点から、最下部の非透液部40Bの高さは、透液部40AXから第2室20に流入する尿によって、第2室20の底のゲル化材22までゲル化する程度とすることが好ましい。 6C shows an example in which the lowermost part of the partition wall 40 is the liquid-permeable part 40AX, but the present invention is not limited to this, and the lowermost part may be the non-liquid-permeable part 40B. In this case, from the viewpoint of gelling all gelling materials, the height of the bottom non-liquid-permeable portion 40B is set at the bottom of the second chamber 20 by the urine flowing into the second chamber 20 from the liquid-permeable portion 40AX. It is preferable that the gel material 22 is gelled.
 本実施形態では、尿を収納するための容器(蓄尿バッグ)を示したが、本発明は尿に限らず、例えば腹水/胸水、胆汁、消化管液、術野浸出液、脳脊髄液、のドレナージ、腹膜透析液などの生体排液をゲルの状態で収納するものであってもよい。 In this embodiment, a container (urine storage bag) for storing urine is shown. However, the present invention is not limited to urine, and for example, drainage of ascites / pleural effusion, bile, gastrointestinal fluid, surgical field exudate, and cerebrospinal fluid. Alternatively, a biological waste fluid such as peritoneal dialysis fluid may be stored in a gel state.
 (第2の実施形態の変形例)
 図12を参照して、第2の実施形態の変形例にかかる容器500を説明する。本変形例の容器500は、第2の実施形態の容器400の構成に加えて、透液部40AXと同様の材料および構造の、尿を吸収可能な吸水シート80をさらに有する。この吸水シート80は、吸水シート80と隔壁40とでゲル化材22の下側を囲うように配置する。
(Modification of the second embodiment)
With reference to FIG. 12, the container 500 concerning the modification of 2nd Embodiment is demonstrated. In addition to the configuration of the container 400 of the second embodiment, the container 500 of the present modification further includes a water absorbing sheet 80 that can absorb urine and has the same material and structure as the liquid-permeable portion 40AX. The water absorbent sheet 80 is disposed so that the water absorbent sheet 80 and the partition wall 40 surround the lower side of the gelled material 22.
 この構造により、容器500に初期に流入した尿を、透液部40AXを介して第1室10から第2室20に移動させてゲル化材22に接触させるだけでなく、吸水シート80を介してもゲル化材22に接触させることができる。このように、尿を外装シート54側に回り込ませることで、気泡やダマの残留を十分に抑制したより均一なゲルを形成できる。 With this structure, not only the urine that initially flows into the container 500 is moved from the first chamber 10 to the second chamber 20 via the liquid permeable portion 40AX and is brought into contact with the gelling material 22, but also via the water absorbing sheet 80. However, it can be brought into contact with the gelling material 22. Thus, by making urine wrap around the exterior sheet 54 side, a more uniform gel can be formed in which the remaining bubbles and lumps are sufficiently suppressed.
 本発明によれば、気泡やダマの残留およびゲル化しない生体排液の残存を抑制することで、生体排液を均一なゲルの状態で収容することが可能な容器を提供することができる。 According to the present invention, it is possible to provide a container capable of containing the biological drainage in a uniform gel state by suppressing the remaining of bubbles and lumps and the residual biological drainage that does not gel.
