容器収容器、及びこれを備えた廃液貯留器並びに廃液吸引システムContainer container, waste liquid reservoir equipped with this, and waste liquid suction system
　本発明は、吸引源の吸引力によって吸引された所定の廃液を収容する廃液収容容器を収容可能な容器収容器、及びこれを備えた廃液貯留器並びに廃液吸引システムに関する。 The present invention relates to a container container capable of accommodating a waste liquid storage container for accommodating a predetermined waste liquid sucked by the suction force of a suction source, a waste liquid reservoir provided with the container container, and a waste liquid suction system.
　医療施設等に配設された吸引源を利用して手術中等に生じる患者の体液や体腔内洗浄用の洗浄液を含む廃液を吸引し、この吸引された廃液を貯留するように構成された廃液吸引システムが知られている。廃液吸引システムは、吸引源の吸引力によって吸引された廃液を貯留可能な廃液貯留器を備えている。この種の廃液貯留器は、通常、廃液を収容する廃液収容容器（ライナー）と、当該廃液収容容器を収容する容器収容器（キャニスタ）とを備えている（例えば特許文献１参照）。 Waste liquid suction configured to suck the waste liquid containing the patient's body fluid and the cleaning liquid for cleaning the body cavity generated during surgery using a suction source arranged in a medical facility, etc., and store the sucked waste liquid. The system is known. The waste liquid suction system includes a waste liquid reservoir capable of storing the waste liquid sucked by the suction force of the suction source. This type of waste liquid reservoir usually includes a waste liquid storage container (liner) for accommodating the waste liquid and a container container (canister) for accommodating the waste liquid storage container (see, for example, Patent Document 1).
　容器収容器は、廃液収容容器を収容する有底筒状の容器本体と、当該容器本体の開口を開閉する開閉蓋体とを備える。開閉蓋体が開けられた状態で容器本体に対する廃液収容容器の出し入れが可能であり、開閉蓋体が閉じられた状態で容器収容器及び廃液収容容器の内部空間の気密性が保持される。開閉蓋体が閉じられた状態において、廃液収容容器内に廃液を収容させる。具体的に、開閉蓋体が閉じられた状態において、吸引源の吸引力によって容器収容器及び廃液収容容器の内部空間が負圧とされ、これに伴って廃液が廃液収容容器内に流入する。 The container container includes a bottomed tubular container body for accommodating the waste liquid storage container and an opening / closing lid for opening and closing the opening of the container body. The waste liquid storage container can be taken in and out of the container body with the opening / closing lid open, and the airtightness of the internal space of the container container and the waste liquid storage container is maintained with the opening / closing lid closed. With the open / close lid closed, the waste liquid is stored in the waste liquid storage container. Specifically, in a state where the opening / closing lid is closed, the suction force of the suction source creates a negative pressure in the internal space of the container container and the waste liquid storage container, and the waste liquid flows into the waste liquid storage container accordingly.
　廃液収容容器内での廃液の収容が完了すると、開閉蓋体を開放して容器本体から廃液収容容器を取り出すことになる。この際、容器収容器内に負圧が残っていると、開閉蓋体を開くことが困難になるという課題がある。 When the storage of the waste liquid in the waste liquid storage container is completed, the opening / closing lid is opened and the waste liquid storage container is taken out from the container body. At this time, if negative pressure remains in the container container, there is a problem that it becomes difficult to open the opening / closing lid.

　本実施形態では、容器本体６１は、有底円筒状の本体部６１１と、本体部６１１の上端に接合された円筒体からなり、容器本体６１の前記上端面部６１２１における上方開口６１２１Ｈを区画する上方構造部６１２と、を有する。容器本体６１は、本体部６１１の上端に上方構造部６１２が接合されることにより、全体として一体に構成されている。 In the present embodiment, the container main body 61 is composed of a bottomed cylindrical main body portion 611 and a cylindrical body joined to the upper end of the main body portion 611, and is an upper portion for partitioning the upper opening 6121H in the upper end surface portion 6121 of the container main body 61. It has a structural portion 612 and. The container main body 61 is integrally formed as a whole by joining the upper structural portion 612 to the upper end of the main body portion 611.
　容器本体６１は、後述のライナー５よりも剛性の高い硬質の合成樹脂により形成されている。容器本体６１において、本体部６１１と上方構造部６１２とは、同一の合成樹脂により形成されていてもよいし、異種の合成樹脂により形成されていてもよい。本実施形態では、容器本体６１内に収容されたライナー５内における廃液ＷＬの収容状態が視認可能となるように、本体部６１１は無色透明な光透過性を有する合成樹脂により形成されている。一方、上方構造部６１２は、キャニスタ６のデザイン性を考慮して着色された合成樹脂もしくは金属により形成されている。 The container body 61 is made of a hard synthetic resin having a higher rigidity than the liner 5 described later. In the container main body 61, the main body portion 611 and the upper structure portion 612 may be formed of the same synthetic resin or may be formed of different kinds of synthetic resins. In the present embodiment, the main body 611 is made of a colorless and transparent synthetic resin having light transmission so that the state of containing the waste liquid WL in the liner 5 housed in the container main body 61 can be visually recognized. On the other hand, the upper structural portion 612 is formed of a synthetic resin or metal colored in consideration of the design of the canister 6.
　図１及び図５に示すように、上方構造部６１２は、吸引源接続部６１２２と大気開放部６１２３とを有する。吸引源接続部６１２２は、前記吸引空間Ｓ１と吸引経路部３の第１経路部材３１とを連通し、吸引源２の吸引力によって前記吸引空間Ｓ１から排出される空気の流路となる空気排出路６１２２１を区画する。空気排出路６１２２１は、円筒体からなる上方構造部６１２の周壁を貫通して設けられる。吸引源接続部６１２２は、吸引経路部３の第１経路部材３１と接続される。これにより、吸引源接続部６１２２の空気排出路６１２２１と第１経路部材３１とが連通し、吸引源２の吸引力によって前記吸引空間Ｓ１から吸引源２へ向かう方向（図１の矢印Ｈ１）に空気が排出されて、前記吸引空間Ｓ１が負圧とされる。なお、空気排出路６１２２１は、容器本体６１の上方構造部６１２に設けられることに限定されず、開閉蓋体６２に設けられていてもよい。 As shown in FIGS. 1 and 5, the upper structural portion 612 has a suction source connecting portion 6122 and an atmospheric opening portion 6123. The suction source connecting portion 6122 communicates the suction space S1 with the first path member 31 of the suction path portion 3, and serves as a flow path for air discharged from the suction space S1 by the suction force of the suction source 2. The road 61221 is partitioned. The air discharge path 61221 is provided so as to penetrate the peripheral wall of the upper structure portion 612 made of a cylindrical body.

The air inflow passage 61231 is provided so as to penetrate the peripheral wall of the upper structure portion 612 made of a cylindrical body. The air inflow passage 61231 is not limited to being provided in the upper structural portion 612 of the container body 61, and may be provided in the opening / closing lid 62. Further, a ventilation valve 64 is arranged in the air inflow passage 61231 of the atmosphere opening portion 6123. Although the details will be described later, the vent valve 64 is a valve body that closes or opens the air inflow passage 61231. When the air inflow path 61231 is closed by the ventilation valve 64, the negative pressure state of the suction space S1 is maintained by the action of the suction force of the suction source 2. On the other hand, in a state where the action of the suction force of the suction source 2 is stopped and the air inflow path 61231 is opened by the ventilation valve 64, the external space S4 via the air inflow path 61231 to the suction space S1 which has been regarded as a negative pressure. Air flows in from. As a result, the suction space S1 is opened to the atmosphere.

　閉塞面部６２４の凹部６２４２は、開閉蓋体６２が前記閉塞位置に配置された状態において、容器本体６１内に収容されたライナー５の上方側に上方空間Ｓ２（図１）を形成する。当接部６２４１は、閉塞面部６２４の外周縁に沿った形状に形成され、開閉蓋体６２が前記閉塞位置に配置された状態において、ライナー５における後述の容器蓋体５２のフランジ部５２１を介して、上方構造部６１２の上端面部６１２１に当接する。この当接部６２４１は、図３及び図４に示すように、第２シール溝６２４１Ａを有する。第２シール溝６２４１Ａは、当接部６２４１に沿った、すなわち、閉塞面部６２４の外周縁に沿った溝である。第２シール溝６２４１Ａには、第２シール部材６２４１Ｂが嵌め込まれる。第２シール部材６２４１Ｂは、弾性変形可能なゴム材料からなるシール部材である。 The recess 6242 of the closed surface portion 624 forms an upper space S2 (FIG. 1) on the upper side of the liner 5 housed in the container body 61 in a state where the opening / closing lid 62 is arranged at the closed position. The contact portion 6241 is formed in a shape along the outer peripheral edge of the closed surface portion 624, and in a state where the opening / closing lid 62 is arranged at the closed position, the contact portion 6241 is passed through the flange portion 521 of the container lid 52 described later in the liner 5. Therefore, it comes into contact with the upper end surface portion 6121 of the upper structure portion 612. The contact portion 6241 has a second seal groove 6241A as shown in FIGS. 3 and 4. The second seal groove 6241A is a groove along the contact portion 6241, that is, along the outer peripheral edge of the closed surface portion 624. The second seal member 6241B is fitted into the second seal groove 6241A. The second sealing member 6241B is a sealing member made of an elastically deformable rubber material.
　開閉蓋体６２が前記閉塞位置に配置された状態においては、詳細については後述するが、ライナー５における容器蓋体５２のフランジ部５２１は、上方から第２シール部材６２４１Ｂが圧接され、下方から前記第１シール部材６１２６Ａが圧接される。換言すると、フランジ部５２１は、開閉蓋体６２が前記閉塞位置に配置された状態において、第１シール部材６１２６Ａと第２シール部材６２４１Ｂとの間に挟み込まれる。これにより、容器本体６１内の前記吸引空間Ｓ１と、前記上方空間Ｓ２との気密性が保持される。なお、開閉蓋体６２が前記閉塞位置に配置された状態においては、ライナー５における容器蓋体５２のフランジ部５２１に形成された複数の貫通穴５２１１（図１，図３）は、フランジ部５２１において第１シール部材６１２６Ａ及び第２シール部材６２４１Ｂが圧接する圧接部分よりも内側に配置され、前記吸引空間Ｓ１と前記上方空間Ｓ２とを連通させる。これにより、吸引源２の吸引力によって前記吸引空間Ｓ１が負圧とされると共に、前記上方空間Ｓ２も負圧とされる。 In the state where the opening / closing lid 62 is arranged at the closed position, the details will be described later, but the flange portion 521 of the container lid 52 in the liner 5 is pressed against the second seal member 6241B from above and described above from below. The first seal member 6126A is pressure-welded. In other words, the flange portion 521 is sandwiched between the first seal member 6126A and the second seal member 6241B in a state where the opening / closing lid 62 is arranged at the closed position. As a result, the airtightness between the suction space S1 in the container body 61 and the upper space S2 is maintained. In the state where the opening / closing lid 62 is arranged at the closed position, the plurality of through holes 5211 (FIGS. 1 and 3) formed in the flange portion 521 of the container lid 52 in the liner 5 have the flange portion 521. The first seal member 6126A and the second seal member 6241B are arranged inside the pressure contact portion to be pressure-welded, and communicate the suction space S1 and the upper space S2. As a result, the suction force of the suction source 2 causes the suction space S1 to have a negative pressure, and the upper space S2 also has a negative pressure.
　天面部６２５は、開閉蓋体６２において閉塞面部６２４に対して厚み方向の反対側に配置された部分である。天面部６２５は、開閉蓋体６２が前記閉塞位置に配置された状態において、外方に露出する。天面部６２５は、閉塞面部６２４と同様に、平面視において切欠き部６２３によって円の一部が切り欠かれた形状に形成される。図２に示すように、天面部６２５は、切欠き部６２３の周辺において傾斜部６２５１を有する。傾斜部６２５１は、開閉蓋体６２が前記閉塞位置に配置された状態において、ライナー５における容器蓋体５２の、切欠き部６２３から露出する廃液導入ポート５２２に面し、切欠き部６２３の端縁から離れるに従い上に傾斜している。 The top surface portion 625 is a portion of the opening / closing lid 62 arranged on the opposite side of the closing surface portion 624 in the thickness direction. The top surface portion 625 is exposed to the outside in a state where the opening / closing lid 62 is arranged at the closed position. Similar to the closed surface portion 624, the top surface portion 625 is formed in a shape in which a part of a circle is cut out by the notch portion 623 in a plan view. As shown in FIG. 2, the top surface portion 625 has an inclined portion 6251 around the notch portion 623. The inclined portion 6251 faces the waste liquid introduction port 522 exposed from the notch 623 of the container lid 52 in the liner 5 in a state where the opening / closing lid 62 is arranged at the closed position, and the end of the notch 623. It slopes upward as it moves away from the edge.
　次に、図１～図７を参照して、開閉操作部材６３について説明する。開閉操作部材６３は、容器本体６１の上方構造部６１２における操作支持部６１２５に支持され、開閉蓋体６２の開閉を操作する部材である。なお、開閉操作部材６３は、容器本体６１の上方構造部６１２に支持されることに限定されず、開閉蓋体６２に支持されていてもよい。開閉操作部材６３は、開閉蓋体６２を開閉させるときに医療従事者（作業者）によって操作される。開閉操作部材６３は、開閉蓋体６２の開放を規制して当該開閉蓋体６２が前記閉塞位置に配置された状態を保持する閉塞保持姿勢と、開閉蓋体６２の前記閉塞位置から前記開放位置への変位に応じた前記上方開口６１２１Ｈの開放を許容する開放許容姿勢との間で、姿勢変更が可能である。なお、開閉操作部材６３が前記閉塞保持姿勢を取った状態が図６に示され、開閉操作部材６３が前記開放許容姿勢を取った状態が図７に示されている。 Next, the opening / closing operation member 63 will be described with reference to FIGS. 1 to 7. The opening / closing operation member 63 is a member that is supported by the operation support portion 6125 in the upper structure portion 612 of the container body 61 and operates the opening / closing of the opening / closing lid body 62. The opening / closing operation member 63 is not limited to being supported by the upper structural portion 612 of the container body 61, and may be supported by the opening / closing lid 62. The opening / closing operation member 63 is operated by a medical worker (worker) when opening / closing the opening / closing lid 62. The opening / closing operation member 63 has a closing holding posture that restricts the opening of the opening / closing lid 62 and holds the opening / closing lid 62 in the closed position, and the opening / closing position from the closing position of the opening / closing lid 62. The posture can be changed from the open allowable posture that allows the opening of the upper opening 6121H according to the displacement to. The state in which the opening / closing operation member 63 is in the closed holding posture is shown in FIG. 6, and the state in which the opening / closing operation member 63 is in the opening allowable posture is shown in FIG.
　開閉操作部材６３は、容器本体６１及び開閉蓋体６２と同様に、ライナー５よりも剛性の高い硬質の合成樹脂により形成されている。本実施形態では、開閉操作部材６３は、容器本体６１の上方構造部６１２及び開閉蓋体６２との区別が容易となるように、これらとは異なる色に着色された合成樹脂により形成されている。 The opening / closing operation member 63 is made of a hard synthetic resin having a higher rigidity than the liner 5, like the container body 61 and the opening / closing lid 62. In the present embodiment, the opening / closing operation member 63 is formed of a synthetic resin colored in a color different from these so that the upper structural portion 612 of the container body 61 and the opening / closing lid 62 can be easily distinguished from each other. ..
　開閉操作部材６３は、操作回動軸部６３１と、押圧操作部６３２と、付勢部６３３と、係合部６３４とを有する。 The opening / closing operation member 63 has an operation rotation shaft portion 631, a pressing operation portion 632, an urging portion 633, and an engaging portion 634.
　操作回動軸部６３１は、容器本体６１の前記容器軸と直交する方向に延びる軸部であって、前記蓋体回動軸部６２１と平行に延びる軸部である。操作回動軸部６３１は、上方構造部６１２の操作支持部６１２５に対して開閉操作部材６３を回動可能に支持する機能を有する。操作回動軸部６３１は、操作支持部６１２５に対して取り外しが可能である。開閉操作部材６３は、操作回動軸部６３１回りの回動が可能となるように、操作支持部６１２５に支持されている。開閉操作部材６３は、操作回動軸部６３１回りの回動によって、前記閉塞保持姿勢と前記開放許容姿勢との間での姿勢変更が可能である。また、開閉操作部材６３は、上方構造部６１２の大気開放部６１２３における空気流入路６１２３１を外側から覆うように、操作回動軸部６３１によって操作支持部６１２５に支持されている。 The operation rotation shaft portion 631 is a shaft portion extending in a direction orthogonal to the container shaft of the container body 61, and is a shaft portion extending in parallel with the lid rotation shaft portion 621. The operation rotation shaft portion 631 has a function of rotatably supporting the opening / closing operation member 63 with respect to the operation support portion 6125 of the upper structure portion 612. The operation rotation shaft portion 631 can be removed from the operation support portion 6125. The opening / closing operation member 63 is supported by the operation support portion 6125 so as to be able to rotate around the operation rotation shaft portion 631. The opening / closing operation member 63 can change its posture between the closed holding posture and the opening allowable posture by rotating around the operation rotating shaft portion 631. Further, the opening / closing operation member 63 is supported by the operation support portion 6125 by the operation rotation shaft portion 631 so as to cover the air inflow path 61231 in the atmosphere opening portion 6123 of the upper structure portion 612 from the outside.
　押圧操作部６３２は、医療従事者（作業者）の押圧操作によって下方に向かう押圧力が付与される。付勢部６３３は、押圧操作部６３２の下方側において上下方向に延びるようにコイルばね６３３１が取り付けられている。コイルばね６３３１は、押圧操作部６３２を上方へ付勢する。係合部６３４は、開閉操作部材６３が前記閉塞保持姿勢を取った状態において、開閉蓋体６２の係合フック６２４３と係合する。係合部６３４が係合フック６２４３と係合した状態においては、開閉蓋体６２の前記閉塞位置に配置された状態が保持される。 The pressing operation unit 632 is applied with a downward pressing force by the pressing operation of a medical worker (worker). A coil spring 6331 is attached to the urging portion 633 so as to extend in the vertical direction on the lower side of the pressing operation portion 632. The coil spring 6331 urges the pressing operation unit 632 upward. The engaging portion 634 engages with the engaging hook 6243 of the opening / closing lid 62 in a state where the opening / closing operation member 63 is in the closed holding posture. In the state where the engaging portion 634 is engaged with the engaging hook 6243, the state of being arranged at the closed position of the opening / closing lid 62 is maintained.
　押圧力の付与によって押圧操作部６３２がコイルばね６３３１の付勢力に抗して押し下げられると、開閉操作部材６３は、前記閉塞保持姿勢から前記開放許容姿勢へと姿勢変更するように、操作回動軸部６３１回りに回動する。この際、係合部６３４と係合フック６２４３との係合状態が解除される。これにより、開閉蓋体６２の前記閉塞位置から前記開放位置への回動が可能となる。一方、押圧操作部６３２に押圧力が付与されていない状態では、コイルばね６３３１の押圧操作部６３２に対する上方への付勢力によって、開閉操作部材６３の前記閉塞保持姿勢が維持される。この際、係合部６３４と係合フック６２４３との係合が可能である。これにより、開閉蓋体６２の前記閉塞位置に配置された状態の保持が可能となる。 When the pressing operation unit 632 is pushed down against the urging force of the coil spring 6331 by applying the pressing force, the opening / closing operation member 63 rotates so as to change the posture from the closed holding posture to the opening allowable posture. It rotates around the shaft portion 631. At this time, the engaged state between the engaging portion 634 and the engaging hook 6243 is released. As a result, the opening / closing lid 62 can be rotated from the closed position to the open position. On the other hand, when the pressing force is not applied to the pressing operation unit 632, the closing holding posture of the opening / closing operation member 63 is maintained by the upward urging force of the coil spring 6331 with respect to the pressing operation unit 632. At this time, the engaging portion 634 and the engaging hook 6243 can be engaged with each other. As a result, the opening / closing lid 62 can be held in the closed position.

The vent valve 64 is a valve body arranged in the air inflow passage 61231 of the air opening portion 6123 in the upper structural portion 612 of the container main body 61. The ventilation valve 64 is connected to the opening / closing operation member 63 via the link member 641 so that the ventilation valve 64 can move inside the operation rotation shaft portion 631 according to the posture change of the opening / closing operation member 63. The ventilation valve 64 has an opening / closing operation member via the link member 641 when the operation rotation shaft portion 631 is removed from the operation support portion 6125, that is, when the opening / closing operation member 63 is removed from the operation support portion 6125. It is possible to release the connection with 63. The vent valve 64 closes or opens the air inflow passage 61231 by moving according to the posture change of the opening / closing operation member 63.
　通気弁６４は、開閉操作部材６３が前記閉塞保持姿勢を取った状態では、空気流入路６１２３１を閉鎖する流路閉鎖位置に配置される（図６参照）。通気弁６４が流路閉鎖位置に配置されて空気流入路６１２３１が閉鎖された状態では、吸引源２の吸引力による前記吸引空間Ｓ１及び前記上方空間Ｓ２の負圧状態が維持される。一方、開閉操作部材６３が前記閉塞保持姿勢から前記開放許容姿勢へと姿勢変更すると、その姿勢変更に応じて通気弁６４は、前記流路閉鎖位置から空気流入路６１２３１を開放する流路開放位置へと移動する（図７参照）。通気弁６４は、開閉操作部材６３の姿勢変更に応じた前記流路閉鎖位置から前記流路開放位置への移動によって、外部空間Ｓ４の空気の空気流入路６１２３１を介した前記吸引空間Ｓ１及び前記上方空間Ｓ２への流入を許容する。通気弁６４が前記流路開放位置に配置されて空気流入路６１２３１が開放された状態では、負圧とされていた前記吸引空間Ｓ１及び前記上方空間Ｓ２へ空気流入路６１２３１を介して外部空間Ｓ４から空気が流入する。これにより、前記吸引空間Ｓ１及び前記上方空間Ｓ２が大気開放される。 The ventilation valve 64 is arranged at a flow path closing position that closes the air inflow passage 61231 when the opening / closing operation member 63 is in the closed holding posture (see FIG. 6). When the vent valve 64 is arranged at the flow path closing position and the air inflow passage 61231 is closed, the negative pressure state of the suction space S1 and the upper space S2 due to the suction force of the suction source 2 is maintained. On the other hand, when the opening / closing operation member 63 changes its posture from the closed holding posture to the opening allowable posture, the ventilation valve 64 opens the air inflow passage 61231 from the flow path closing position in response to the changing posture. (See FIG. 7). The ventilation valve 64 moves from the flow path closing position to the flow path opening position in response to a change in the posture of the opening / closing operation member 63, whereby the suction space S1 and the suction space S1 and the said through the air inflow path 61231 of the external space S4. Allows inflow into the upper space S2. When the vent valve 64 is arranged at the flow path open position and the air inflow path 61231 is opened, the external space S4 via the air inflow path 61231 to the suction space S1 and the upper space S2, which are negative pressures. Air flows in from. As a result, the suction space S1 and the upper space S2 are opened to the atmosphere.
　＜ライナーの構成＞
　次に、主として図１及び図３を参照して、ライナー５について説明する。ライナー５は、キャニスタ６内に収容される廃液収容容器である。ライナー５は、その内部が負圧とされることによって吸引起点部３３から廃液ＷＬを吸引し、その吸引された廃液ＷＬを収容する。ライナー５は、上方及び下方に開口する円筒状の筒体５１と、筒体５１の上方の開口を塞ぐ容器蓋体５２と、筒体５１の下方の開口を塞ぐ底板５３と、を含む。ライナー５は、筒体５１の上端に容器蓋体５２が接合され、筒体５１の下端に底板５３が接合されることにより、全体として一体に構成されている。 <Liner configuration>
Next, the liner 5 will be described mainly with reference to FIGS. 1 and 3. The liner 5 is a waste liquid storage container housed in the canister 6. The liner 5 sucks the waste liquid WL from the suction starting point 33 due to the negative pressure inside the liner 5, and accommodates the sucked waste liquid WL. The liner 5 includes a cylindrical cylinder 51 that opens upward and downward, a container lid 52 that closes the opening above the cylinder 51, and a bottom plate 53 that closes the opening below the cylinder 51. The liner 5 is integrally formed as a whole by joining the container lid 52 to the upper end of the tubular body 51 and joining the bottom plate 53 to the lower end of the tubular body 51.
　図１に示すように、筒体５１は、ライナー５において廃液ＷＬを収容する廃液収容空間Ｓ３を区画する本体部分を構成する。筒体５１は、上下方向に延びる筒体軸に沿って長手の円筒状に形成される。筒体５１の前記筒体軸は、筒体５１の中心軸を表し、ライナー５がキャニスタ６内に収容された状態において、廃液貯留器４の中心軸Ｊ１と同軸上に配置され、上下方向に延びる。筒体５１は、キャニスタ６よりも剛性が低く、可撓性を有する合成樹脂により形成されている。 As shown in FIG. 1, the tubular body 51 constitutes a main body portion that partitions the waste liquid storage space S3 that stores the waste liquid WL in the liner 5. The tubular body 51 is formed in a long cylindrical shape along a tubular body axis extending in the vertical direction. The tubular axis of the tubular body 51 represents the central axis of the tubular body 51, and is arranged coaxially with the central axis J1 of the waste liquid reservoir 4 in a state where the liner 5 is housed in the canister 6 in the vertical direction. Extend. The tubular body 51 is made of a synthetic resin having lower rigidity and flexibility than the canister 6.
　筒体５１は、可撓性を有する合成樹脂により形成されることによって、前記筒体軸に沿った圧縮力が付与されることで押し潰された形態の圧縮変形が可能である。筒体５１の圧縮変形によってライナー５のコンパクト化が可能となり、ライナー５の保管時や輸送時においてライナー５の占有スペースを小さくすることができる。なお、筒体５１を圧縮変形させるときには、前記筒体軸に沿って筒体５１に圧縮力を付与するようにすればよいが、前記筒体軸回りに捻転させながら筒体５１に圧縮力を付与することが望ましい。これにより、筒体５１の圧縮変形後の形態において、筒体５１の一部が径方向外方に飛び出る形態となることを防止し、ライナー５のより適切なコンパクト化が可能となる。なお、圧縮変形状態の筒体５１は、前記筒体軸に沿った引張力が付与されることで、前記筒体軸に沿って長手の円筒状に復元される。このように筒体５１が円筒状とされた状態でライナー５はキャニスタ６にセットされ、ライナー５がキャニスタ６に収容された状態とされる。 By forming the tubular body 51 with a flexible synthetic resin, a compressive force along the tubular body axis is applied, so that the tubular body 51 can be compressed and deformed in a crushed form. The compression deformation of the tubular body 51 makes it possible to make the liner 5 compact, and the space occupied by the liner 5 can be reduced during storage and transportation of the liner 5. When compressing and deforming the tubular body 51, a compressive force may be applied to the tubular body 51 along the tubular body axis, but the compressive force is applied to the tubular body 51 while twisting around the tubular body axis. It is desirable to give it. As a result, in the form of the tubular body 51 after compression deformation, it is possible to prevent a part of the tubular body 51 from protruding outward in the radial direction, and it is possible to make the liner 5 more appropriate and compact. The tubular body 51 in the compression-deformed state is restored to a long cylindrical shape along the tubular axis by applying a tensile force along the tubular axis. The liner 5 is set in the canister 6 with the tubular body 51 having a cylindrical shape in this way, and the liner 5 is housed in the canister 6.
　底板５３は、円板状に形成され、筒体５１の下端に接合されることにより、当該筒体５１の下方の開口を塞ぐ部材である。底板５３は、筒体５１よりも剛性の高い合成樹脂により形成されており、筒体５１のように可撓性を有していない。本実施形態では、底板５３は、筒体５１との区別が容易となるように、着色された合成樹脂により形成されている。 The bottom plate 53 is a member that is formed in a disk shape and is joined to the lower end of the tubular body 51 to close the opening below the tubular body 51. The bottom plate 53 is made of a synthetic resin having a higher rigidity than the tubular body 51, and does not have flexibility like the tubular body 51. In the present embodiment, the bottom plate 53 is formed of a colored synthetic resin so as to be easily distinguished from the tubular body 51.
　容器蓋体５２は、上方から見た平面視で円形状に形成され、筒体５１の上端に接合されることにより、当該筒体５１の上方の開口を塞ぐ蓋体である。容器蓋体５２は、底板５３と同様に、筒体５１よりも剛性の高い合成樹脂により形成されており、筒体５１のように可撓性を有していない。本実施形態では、容器蓋体５２は、筒体５１との区別が容易となるように、底板５３と同一の色に着色された合成樹脂により形成されている。 The container lid 52 is a lid that is formed in a circular shape when viewed from above and is joined to the upper end of the cylinder 51 to close the opening above the cylinder 51. Like the bottom plate 53, the container lid 52 is made of a synthetic resin having a higher rigidity than the cylinder 51, and does not have flexibility like the cylinder 51. In the present embodiment, the container lid 52 is formed of a synthetic resin colored in the same color as the bottom plate 53 so as to be easily distinguished from the cylinder 51.
　容器蓋体５２は、フランジ部５２１と、廃液導入ポート５２２と、廃液排出ポート５２３と、連通ポート５２６と、廃液処理剤収納部５２４と、把持部材５２５と、を有する。 The container lid 52 has a flange portion 521, a waste liquid introduction port 522, a waste liquid discharge port 523, a communication port 526, a waste liquid treatment agent storage portion 524, and a gripping member 525.
　フランジ部５２１は、容器蓋体５２が筒体５１の上端に接合された状態において、筒体５１に対して径方向外方に延出した部分である（図１参照）。フランジ部５２１は、ライナー５がキャニスタ６に収容された状態において、容器本体６１の上方構造部６１２における上端面部６１２１に当接する。更に、キャニスタ６の開閉蓋体６２が前記閉塞位置に配置された状態においては、フランジ部５２１は、当該開閉蓋体６２の閉塞面部６２４における当接部６２４１と、上方構造部６１２における上端面部６１２１との間に挟み込まれる。すなわち、フランジ部５２１は、開閉蓋体６２が前記閉塞位置に配置された状態において、前記第１シール部材６１２６Ａと前記第２シール部材６２４１Ｂとの間に挟み込まれて両シール部材が圧接する圧接部分を有する。既述の通り、開閉蓋体６２の閉塞面部６２４は、切欠き部６２３に対応して円の一部が切り欠かれた形状を有している。このため、フランジ部５２１の下面は、全周にわたって前記第１シール部材６１２６Ａが圧接しているが、フランジ部５２１の上面は、切欠き部６２３に対応した部分を除いて前記第２シール部材６２４１Ｂが圧接している。換言すると、フランジ部５２１において、前記第１シール部材６１２６Ａ及び前記第２シール部材６２４１Ｂの両シール部材が圧接する圧接部分は、切欠き部６２３に対応した部分を除いた残余の部分となる。 The flange portion 521 is a portion extending outward in the radial direction with respect to the tubular body 51 in a state where the container lid 52 is joined to the upper end of the tubular body 51 (see FIG. 1). The flange portion 521 abuts on the upper end surface portion 6121 of the upper structural portion 612 of the container body 61 in a state where the liner 5 is housed in the canister 6. Further, when the opening / closing lid 62 of the canister 6 is arranged at the closed position, the flange portion 521 has a contact portion 6241 at the closing surface portion 624 of the opening / closing lid 62 and an upper end surface portion 6121 of the upper structure portion 612. It is sandwiched between and. That is, the flange portion 521 is a pressure contact portion where the opening / closing lid 62 is sandwiched between the first seal member 6126A and the second seal member 6241B and the two seal members are in pressure contact with each other when the opening / closing lid 62 is arranged at the closed position. Has. As described above, the closed surface portion 624 of the opening / closing lid 62 has a shape in which a part of the circle is cut out corresponding to the cutout portion 623. Therefore, the lower surface of the flange portion 521 is in pressure contact with the first seal member 6126A over the entire circumference, but the upper surface of the flange portion 521 is the second seal member 6241B except for the portion corresponding to the notch portion 623. Is in pressure contact. In other words, in the flange portion 521, the pressure contact portion where both the seal members of the first seal member 6126A and the second seal member 6241B are in pressure contact with each other is a residual portion excluding the portion corresponding to the notch portion 623.
　フランジ部５２１には、厚み方向（上下方向）に貫通して設けられた複数の貫通穴５２１１が形成されている。複数の貫通穴５２１１は、フランジ部５２１において、前記圧接部分よりも内側に配置され、前記吸引空間Ｓ１と前記上方空間Ｓ２とを連通させる。これにより、吸引源２の吸引力によって前記吸引空間Ｓ１が負圧とされると共に、前記上方空間Ｓ２も負圧とされる。なお、フランジ部５２１において切欠き部６２３に対応した部分には、貫通穴５２１１は形成されていない。 The flange portion 521 is formed with a plurality of through holes 5211 provided so as to penetrate in the thickness direction (vertical direction). The plurality of through holes 5211 are arranged inside the pressure contact portion in the flange portion 521 to communicate the suction space S1 and the upper space S2. As a result, the suction force of the suction source 2 causes the suction space S1 to have a negative pressure, and the upper space S2 also has a negative pressure. The through hole 5211 is not formed in the portion of the flange portion 521 corresponding to the notch portion 623.
　連通ポート５２６は、容器蓋体５２が筒体５１の上端に接合された状態において、筒体５１よりも径方向の内側で容器蓋体５２を貫通して設けられた、上下方向に延びるポートである。連通ポート５２６の上端部は、キャニスタ６の開閉蓋体６２が前記閉塞位置に配置された状態において、容器本体６１内に収容されたライナー５の上方側に形成された前記上方空間Ｓ２内に配置される。一方、連通ポート５２６の下端部は、筒体５１の廃液収容空間Ｓ３内に配置される。すなわち、連通ポート５２６は、ライナー５の内部に相当する筒体５１の廃液収容空間Ｓ３と、ライナー５の上方側に形成された前記上方空間Ｓ２とを連通する。これにより、吸引源２の吸引力によって前記吸引空間Ｓ１及び前記上方空間Ｓ２が負圧とされることに伴って、筒体５１の廃液収容空間Ｓ３も負圧とされる。 The communication port 526 is a port extending in the vertical direction provided through the container lid 52 inside the cylinder 51 in the radial direction in a state where the container lid 52 is joined to the upper end of the cylinder 51. is there. The upper end of the communication port 526 is arranged in the upper space S2 formed on the upper side of the liner 5 housed in the container body 61 in a state where the opening / closing lid 62 of the canister 6 is arranged in the closed position. Will be done. On the other hand, the lower end of the communication port 526 is arranged in the waste liquid storage space S3 of the tubular body 51. That is, the communication port 526 communicates with the waste liquid storage space S3 of the tubular body 51 corresponding to the inside of the liner 5 and the upper space S2 formed on the upper side of the liner 5. As a result, the suction force of the suction source 2 causes the suction space S1 and the upper space S2 to have a negative pressure, and the waste liquid storage space S3 of the cylinder 51 also has a negative pressure.
　なお、連通ポート５２６は、その下端部に止水フィルタが設けられている。ライナー５においては、筒体５１の廃液収容空間Ｓ３内に収容された廃液ＷＬの液面が連通ポート５２６の下端部に設けられた止水フィルタに達した場合に、廃液収容空間Ｓ３内に収容された廃液ＷＬが満杯状態になったとされる。ここで、廃液排出ポート５２３は、容器蓋体５２が筒体５１の上端に接合された状態において、筒体５１よりも径方向の内側で容器蓋体５２を貫通して設けられた、上下方向に延びるポートである。廃液排出ポート５２３は、ライナー５がキャニスタ６から取り出された状態において、ライナー５内（筒体５１の廃液収容空間Ｓ３内）に収容された廃液ＷＬを排出するためのポートである。図３に示すように、容器蓋体５２には、把持部材５２５が取り付けられている。医療従事者（作業者）は、把持部材５２５を把持しつつ、ライナー５をキャニスタ６から取り出すことができる。 The communication port 526 is provided with a water stop filter at the lower end thereof. In the liner 5, when the liquid level of the waste liquid WL stored in the waste liquid storage space S3 of the cylinder 51 reaches the water stop filter provided at the lower end of the communication port 526, the liner 5 is stored in the waste liquid storage space S3. It is said that the waste liquid WL that has been used is full. Here, the waste liquid discharge port 523 is provided in the vertical direction so as to penetrate the container lid 52 inside the cylinder 51 in the radial direction in a state where the container lid 52 is joined to the upper end of the cylinder 51. It is a port that extends to. The waste liquid discharge port 523 is a port for discharging the waste liquid WL stored in the liner 5 (in the waste liquid storage space S3 of the cylinder 51) when the liner 5 is taken out from the canister 6. As shown in FIG. 3, a gripping member 525 is attached to the container lid 52. The medical worker (worker) can take out the liner 5 from the canister 6 while gripping the gripping member 525.
　廃液導入ポート５２２は、容器蓋体５２が筒体５１の上端に接合された状態において、筒体５１よりも径方向の内側で容器蓋体５２を貫通して設けられた、上下方向に延びるポートである。本実施形態では、容器蓋体５２を上方から見た平面視において、廃液排出ポート５２３と廃液導入ポート５２２とは、容器蓋体５２の中心を対称点とする点対称な位置関係にある。換言すると、容器蓋体５２を上方から見た平面視において、廃液排出ポート５２３と廃液導入ポート５２２とは、容器蓋体５２の中心を通る仮想線上において、互いに対向配置されている。なお、容器蓋体５２の中心は、廃液貯留器４の中心軸Ｊ１と同軸上の、筒体５１の前記筒体軸上に配置される。 The waste liquid introduction port 522 is a port extending in the vertical direction provided through the container lid 52 inside the cylinder 51 in the radial direction in a state where the container lid 52 is joined to the upper end of the cylinder 51. Is. In the present embodiment, when the container lid 52 is viewed from above, the waste liquid discharge port 523 and the waste liquid introduction port 522 have a point-symmetrical positional relationship with the center of the container lid 52 as a point of symmetry. In other words, in a plan view of the container lid 52 viewed from above, the waste liquid discharge port 523 and the waste liquid introduction port 522 are arranged to face each other on a virtual line passing through the center of the container lid 52. The center of the container lid 52 is arranged on the tubular axis of the tubular body 51, coaxial with the central axis J1 of the waste liquid reservoir 4.
　廃液導入ポート５２２は、キャニスタ６の開閉蓋体６２が前記閉塞位置に配置された状態において、切欠き部６２３から露出するように、容器蓋体５２から上方側へ突出している。廃液導入ポート５２２は、吸引経路部３の第２経路部材３２と接続される。廃液導入ポート５２２は、吸引源２の吸引力によって前記吸引空間Ｓ１及び前記上方空間Ｓ２が負圧とされることに応じて、ライナー５の廃液収容空間Ｓ３が負圧とされると、吸引起点部３３から吸引された廃液ＷＬを、前記廃液収容空間Ｓ３内に導入する。すなわち、吸引源２の吸引力によってライナー５の廃液収容空間Ｓ３が負圧とされた場合、吸引起点部３３から吸引された廃液ＷＬは、第２経路部材３２及び廃液導入ポート５２２を流れて（図１の矢印Ｈ２方向に流れて）、ライナー５の廃液収容空間Ｓ３内に収容される。 The waste liquid introduction port 522 projects upward from the container lid 52 so as to be exposed from the notch 623 in a state where the opening / closing lid 62 of the canister 6 is arranged at the closed position. The waste liquid introduction port 522 is connected to the second path member 32 of the suction path portion 3. The waste liquid introduction port 522 has a suction starting point when the waste liquid storage space S3 of the liner 5 has a negative pressure in response to the negative pressure of the suction space S1 and the upper space S2 due to the suction force of the suction source 2. The waste liquid WL sucked from the unit 33 is introduced into the waste liquid storage space S3. That is, when the waste liquid storage space S3 of the liner 5 is made a negative pressure by the suction force of the suction source 2, the waste liquid WL sucked from the suction starting point 33 flows through the second path member 32 and the waste liquid introduction port 522 ( (Flowing in the direction of arrow H2 in FIG. 1), the liner 5 is accommodated in the waste liquid accommodating space S3.
　廃液処理剤収納部５２４は、容器蓋体５２において、廃液収容空間Ｓ３内に収容された廃液ＷＬを処理するための廃液処理剤を収納する部分である。図３に示すように、廃液処理剤収納部５２４は、容器蓋体５２の中央において筒体５１よりも径方向の内側で、且つ、廃液導入ポート５２２及び連通ポート５２６よりも内側に配置される。開閉蓋体６２が前記開放位置に配置された状態では、廃液処理剤収納部５２４の上側部分が露出する。この状態で、廃液処理剤収納部５２４に対する上方からの押圧力が医療従事者（作業者）によって付与された場合、廃液処理剤収納部５２４は、廃液処理剤の収納状態が解除される。これにより、廃液処理剤収納部５２４に収納されていた廃液処理剤が、ライナー５の廃液収容空間Ｓ３内へ添加される。 The waste liquid treatment agent storage unit 524 is a portion of the container lid 52 that stores the waste liquid treatment agent for treating the waste liquid WL stored in the waste liquid storage space S3. As shown in FIG. 3, the waste liquid treatment agent storage portion 524 is arranged in the center of the container lid 52 in the radial direction of the cylinder 51 and inside of the waste liquid introduction port 522 and the communication port 526. .. When the opening / closing lid 62 is arranged in the open position, the upper portion of the waste liquid treatment agent storage portion 524 is exposed. In this state, when a pressing force from above on the waste liquid treatment agent storage unit 524 is applied by a medical worker (worker), the waste liquid treatment agent storage unit 524 is released from the storage state of the waste liquid treatment agent. As a result, the waste liquid treatment agent stored in the waste liquid treatment agent storage unit 524 is added into the waste liquid storage space S3 of the liner 5.
　廃液処理剤収納部５２４に収納される廃液処理剤としては、凝固剤や凝集剤を挙げることができる。凝固剤は、廃液ＷＬを凝固させることが可能な処理剤である。凝固剤としては、粉末状、粒状、塊状などの固体状のものが用いられる。ただし、廃液ＷＬとの接触面積を可及的に大きくするために、凝固剤は、粉末状又は粒状であるのが望ましい。ライナー５の廃液収容空間Ｓ３内に収容された廃液ＷＬに凝固剤が添加されると、廃液ＷＬが凝固剤によって凝固する。一方、凝集剤は、廃液ＷＬに含まれる成分を凝集させてライナー５の廃液収容空間Ｓ３内において凝集物を生成させることが可能な処理剤である。具体的には、凝集剤は、例えば、血液に含まれる細胞成分である赤血球、液状成分である血漿に含まれるタンパク質などを凝集させる。凝集剤としては、粉末状、粒状、塊状などの固体状のものが用いられる。ただし、廃液ＷＬに分散しやすいようにするために、凝集剤は、粉末状又は粒状であるのが望ましい。ライナー５の廃液収容空間Ｓ３内に収容された廃液ＷＬに凝集剤が添加されると、廃液ＷＬに含まれる成分が凝集剤によって凝集物として廃液収容空間Ｓ３内に沈殿する。これにより、廃液収容空間Ｓ３内において廃液ＷＬが、上澄み液と凝集物とに分離される。 Examples of the waste liquid treatment agent stored in the waste liquid treatment agent storage unit 524 include a coagulant and a coagulant. The coagulant is a treatment agent capable of coagulating the waste liquid WL. As the coagulant, a solid substance such as powder, granules, and lumps is used. However, in order to increase the contact area with the waste liquid WL as much as possible, it is desirable that the coagulant is powdery or granular. When a coagulant is added to the waste liquid WL housed in the waste liquid storage space S3 of the liner 5, the waste liquid WL is coagulated by the coagulant. On the other hand, the coagulant is a treatment agent capable of agglutinating the components contained in the waste liquid WL to generate agglomerates in the waste liquid storage space S3 of the liner 5. Specifically, the flocculant aggregates, for example, red blood cells, which are cell components contained in blood, proteins contained in plasma, which is a liquid component, and the like. As the coagulant, a solid substance such as powder, granule, or lump is used. However, it is desirable that the flocculant is powdery or granular so that it can be easily dispersed in the waste liquid WL. When a flocculant is added to the waste liquid WL housed in the waste liquid storage space S3 of the liner 5, the components contained in the waste liquid WL are precipitated as agglomerates in the waste liquid storage space S3 by the coagulant. As a result, the waste liquid WL is separated into the supernatant liquid and the agglomerate in the waste liquid storage space S3.
　［廃液貯留器の取扱いの態様］
　以上説明した通り、廃液貯留器４においては、キャニスタ６内にライナー５が収容された状態で吸引源２の吸引力が作用すると、吸引起点部３３から吸引された廃液ＷＬがライナー５の廃液収容空間Ｓ３内に収容される。キャニスタ６の容器本体６１における上方構造部６１２には開閉操作部材６３が支持され、この開閉操作部材６３にはリンク部材６４１を介して通気弁６４が連結されている。 [Handling mode of waste liquid reservoir]
As described above, in the waste liquid reservoir 4, when the suction force of the suction source 2 acts while the liner 5 is housed in the canister 6, the waste liquid WL sucked from the suction starting point 33 stores the waste liquid of the liner 5. It is housed in space S3. An opening / closing operation member 63 is supported on the upper structure portion 612 of the container body 61 of the canister 6, and a vent valve 64 is connected to the opening / closing operation member 63 via a link member 641.
　開閉操作部材６３が前記閉塞保持姿勢を取った状態では、キャニスタ６において開閉蓋体６２の前記閉塞位置に配置された状態が保持されると共に、通気弁６４が前記空気流入路６１２３１を閉鎖する前記流路閉鎖位置に配置される。この状態では、キャニスタ６の容器本体６１内においてライナー５の外側の前記吸引空間Ｓ１が密閉空間とされる。この状態で吸引源２の吸引力が作用すると前記吸引空間Ｓ１が負圧とされ、これに伴って廃液ＷＬがライナー５の廃液収容空間Ｓ３内に流入する。このようにしてライナー５の廃液収容空間Ｓ３内に廃液ＷＬを収容することができる。 When the opening / closing operation member 63 is in the closed holding posture, the canister 6 is maintained in a state of being arranged at the closed position of the opening / closing lid 62, and the vent valve 64 closes the air inflow passage 61231. It is placed in the flow path closed position. In this state, the suction space S1 outside the liner 5 in the container body 61 of the canister 6 is a closed space. When the suction force of the suction source 2 acts in this state, the suction space S1 becomes a negative pressure, and the waste liquid WL flows into the waste liquid storage space S3 of the liner 5 accordingly. In this way, the waste liquid WL can be stored in the waste liquid storage space S3 of the liner 5.
　一方、吸引源２の吸引力の作用が停止された状態において、開閉操作部材６３が前記閉塞保持姿勢から前記開放許容姿勢へと姿勢変更すると、その姿勢変更に応じて通気弁６４が、前記流路閉鎖位置から前記空気流入路６１２３１を開放する前記流路開放位置へと移動する。これにより、外部空間Ｓ４の空気が空気流入路６１２３１を介してキャニスタ６内の前記吸引空間Ｓ１及び前記上方空間Ｓ２内へ流入し、当該吸引空間Ｓ１が大気開放される。このため、開閉操作部材６３が前記開放許容姿勢を取った状態で開閉蓋体６２を開放するときに、キャニスタ６内の前記吸引空間Ｓ１及び前記上方空間Ｓ２に負圧が残ることを防止することができる。この結果、開閉蓋体６２を容易に開放することができ、開閉蓋体６２が前記開放位置に配置された状態において容器本体６１に対するライナー５の出し入れが可能となる。 On the other hand, when the opening / closing operation member 63 changes its posture from the closed holding posture to the opening allowable posture in a state where the action of the suction force of the suction source 2 is stopped, the ventilation valve 64 moves the flow in response to the change in the posture. It moves from the path closing position to the flow path opening position that opens the air inflow path 61231. As a result, the air in the external space S4 flows into the suction space S1 and the upper space S2 in the canister 6 through the air inflow path 61231, and the suction space S1 is opened to the atmosphere. Therefore, when the opening / closing lid 62 is opened while the opening / closing operation member 63 is in the opening allowable posture, it is possible to prevent negative pressure from remaining in the suction space S1 and the upper space S2 in the canister 6. Can be done. As a result, the opening / closing lid 62 can be easily opened, and the liner 5 can be taken in and out of the container body 61 while the opening / closing lid 62 is arranged at the open position.
　また、既述の通り、キャニスタ６の容器本体６１の上方構造部６１２において、吸引源接続部６１２２には、吸引源２の吸引力によって前記吸引空間Ｓ１及び前記上方空間Ｓ２から排出される空気の流路となる空気排出路６１２２１が設けられている。このような構成では、吸引源２の吸引力によって前記吸引空間Ｓ１及び前記上方空間Ｓ２内の空気が空気排出路６１２２１を介して排出されることにより、前記吸引空間Ｓ１及び前記上方空間Ｓ２が負圧とされる。ここで、外部空間Ｓ４の空気が前記吸引空間Ｓ１及び前記上方空間Ｓ２へ流入する流路となる空気流入路６１２３１は、空気排出路６１２２１よりも圧力損失が大きいことが望ましい。このような空気流入路６１２３１と空気排出路６１２２１との圧力損失の関係は、例えば次のように実現することができる。 Further, as described above, in the upper structural portion 612 of the container body 61 of the canister 6, the suction source connecting portion 6122 is filled with the air discharged from the suction space S1 and the upper space S2 by the suction force of the suction source 2. An air discharge path 61221 that serves as a flow path is provided. In such a configuration, the suction force of the suction source 2 causes the air in the suction space S1 and the upper space S2 to be discharged through the air discharge path 61221, so that the suction space S1 and the upper space S2 are negative. It is pressured. Here, it is desirable that the air inflow passage 61231, which is a flow path through which the air in the external space S4 flows into the suction space S1 and the upper space S2, has a larger pressure loss than the air discharge passage 61221. Such a relationship of pressure loss between the air inflow path 61231 and the air discharge path 61221 can be realized, for example, as follows.
　キャニスタ６の容器本体６１の上方構造部６１２において、空気排出路６１２２１の最上流端の排出口６１２２Ｈと、空気流入路６１２３１の最下流端の流入口６１２３Ｈとは、上方構造部６１２の周壁の内周面に形成された開口である。すなわち、空気排出路６１２２１の排出口６１２２Ｈと空気流入路６１２３１の流入口６１２３Ｈとは、容器本体６１内の前記吸引空間Ｓ１に面している。このような排出口６１２２Ｈ及び流入口６１２３Ｈの開口面積について、流入口６１２３Ｈの開口面積を排出口６１２２Ｈの開口面積よりも小さい値に設定することによって、空気流入路６１２３１の圧力損失を、空気排出路６１２２１の圧力損失よりも大きくすることができる。これにより、吸引源２の吸引力によって前記吸引空間Ｓ１及び前記上方空間Ｓ２内の空気が空気排出路６１２２１を介して排出されて前記吸引空間Ｓ１が負圧とされる状態が継続されているときに、開閉操作部材６３が誤って操作されたとしても、前記吸引空間Ｓ１及び前記上方空間Ｓ２の負圧状態が保持される。このため、開閉操作部材６３の誤操作による前記閉塞保持姿勢から前記開放許容姿勢への姿勢変更を抑止することができる。 In the upper structural portion 612 of the container body 61 of the canister 6, the discharge port 6122H at the most upstream end of the air discharge passage 61221 and the inflow port 6123H at the most downstream end of the air inflow passage 61231 are inside the peripheral wall of the upper structural portion 612. It is an opening formed on the peripheral surface. That is, the discharge port 6122H of the air discharge path 61221 and the inflow port 6123H of the air inflow path 61231 face the suction space S1 in the container body 61. With respect to the opening areas of the discharge port 6122H and the inflow port 6123H, the pressure loss of the air inflow path 61231 is reduced by setting the opening area of the inflow port 6123H to a value smaller than the opening area of the discharge port 6122H. It can be greater than the pressure loss of 61221. As a result, when the air in the suction space S1 and the upper space S2 is discharged through the air discharge path 61221 by the suction force of the suction source 2, the suction space S1 is kept in a negative pressure state. Even if the opening / closing operation member 63 is erroneously operated, the negative pressure state of the suction space S1 and the upper space S2 is maintained. Therefore, it is possible to prevent the posture change from the closed holding posture to the opening allowable posture due to an erroneous operation of the opening / closing operation member 63.
　また、既述の通り、開閉蓋体６２は、蓋体回動軸部６２１回りの回動によって前記閉塞位置と前記開放位置との間での変位が可能であり、開閉操作部材６３は、操作回動軸部６３１回りの回動によって前記閉塞保持姿勢と前記開放許容姿勢との間での姿勢変更が可能である。開閉操作部材６３は、上方構造部６１２の大気開放部６１２３における空気流入路６１２３１を外側から覆うように、操作回動軸部６３１によって操作支持部６１２５に支持されている。これにより、不用意にゴミ等の異物が空気流入路６１２３１を介して前記吸引空間Ｓ１内に進入することを、開閉操作部材６３によって抑制することができる。 Further, as described above, the opening / closing lid 62 can be displaced between the closed position and the open position by rotating around the lid rotating shaft portion 621, and the opening / closing operation member 63 can be operated. The posture can be changed between the closed holding posture and the opening allowable posture by rotating around the rotating shaft portion 631. The opening / closing operation member 63 is supported by the operation support portion 6125 by the operation rotation shaft portion 631 so as to cover the air inflow path 61231 in the atmosphere opening portion 6123 of the upper structure portion 612 from the outside. As a result, the opening / closing operation member 63 can prevent foreign matter such as dust from inadvertently entering the suction space S1 via the air inflow path 61231.
　そして、通気弁６４は、操作回動軸部６３１よりも内側において開閉操作部材６３の姿勢変更に応じて移動するように、リンク部材６４１を介して開閉操作部材６３に連結されている。ここで、操作回動軸部６３１が操作支持部６１２５から取り外されて、開閉操作部材６３が操作支持部６１２５から取り外された状態において、通気弁６４は、リンク部材６４１を介した開閉操作部材６３との連結の解除が可能である。このような構成では、通気弁６４を清掃するときや、通気弁６４を交換するときには、操作支持部６１２５から操作回動軸部６３１を取り外し、その後、開閉操作部材６３に対してリンク部材６４１を介した連結を解除することにより、通気弁６４を取り外すことができる。 Then, the ventilation valve 64 is connected to the opening / closing operation member 63 via the link member 641 so as to move inside the operation rotation shaft portion 631 according to the posture change of the opening / closing operation member 63. Here, in a state where the operation rotation shaft portion 631 is removed from the operation support portion 6125 and the opening / closing operation member 63 is removed from the operation support portion 6125, the ventilation valve 64 is the opening / closing operation member 63 via the link member 641. It is possible to release the connection with. In such a configuration, when cleaning the ventilation valve 64 or replacing the ventilation valve 64, the operation rotation shaft portion 631 is removed from the operation support portion 6125, and then the link member 641 is attached to the opening / closing operation member 63. The vent valve 64 can be removed by releasing the connection via the vent valve 64.
　また、既述の通り、キャニスタ６に収容されるライナー５の容器蓋体５２には、廃液導入ポート５２２が設けられている。この廃液導入ポート５２２には、吸引起点部３３から廃液貯留器４に至る吸引経路を構成する可撓性チューブ等の第２経路部材３２が、接続される。廃液導入ポート５２２に第２経路部材３２が接続された状態で、吸引源２の吸引力によってキャニスタ６内の前記吸引空間Ｓ１及び前記上方空間Ｓ２が負圧とされることにより、吸引起点部３３から吸引された廃液ＷＬを廃液導入ポート５２２からライナー５の廃液収容空間Ｓ３内に導入することができる。そして、キャニスタ６の開閉蓋体６２において、蓋体回動軸部６２１が取り付けられる軸取付部６２２と、廃液導入ポート５２２の露出を許容する切欠き部６２３とは、開閉蓋体６２の中心６２Ｓを対称点とする点対称な位置関係にある。これにより、廃液導入ポート５２２に接続された第２経路部材３２の位置を、開閉蓋体６２が蓋体回動軸部６２１回りに回動したときの切欠き部６２３の回動軌跡から外れた位置に設定することが、容易となる。このため、廃液導入ポート５２２に第２経路部材３２が接続された状態のままで、開閉蓋体６２が前記閉塞位置から前記開放位置に向かって蓋体回動軸部６２１回りに回動したとしても、第２経路部材３２が開閉蓋体６２に干渉することを抑制することができる。 Further, as described above, the container lid 52 of the liner 5 housed in the canister 6 is provided with a waste liquid introduction port 522. A second path member 32 such as a flexible tube forming a suction path from the suction starting point 33 to the waste liquid reservoir 4 is connected to the waste liquid introduction port 522. With the second path member 32 connected to the waste liquid introduction port 522, the suction force of the suction source 2 makes the suction space S1 and the upper space S2 in the canister 6 negative pressure, so that the suction starting point 33 The waste liquid WL sucked from the waste liquid WL can be introduced into the waste liquid storage space S3 of the liner 5 from the waste liquid introduction port 522. In the opening / closing lid 62 of the canister 6, the shaft mounting portion 622 to which the lid rotating shaft portion 621 is attached and the notch portion 623 that allows the exposure of the waste liquid introduction port 522 are formed at the center 62S of the opening / closing lid 62. There is a point-symmetrical positional relationship with the point of symmetry. As a result, the position of the second path member 32 connected to the waste liquid introduction port 522 deviates from the rotation locus of the notch portion 623 when the opening / closing lid 62 rotates around the lid rotation shaft portion 621. It is easy to set the position. Therefore, assuming that the opening / closing lid 62 rotates around the lid rotating shaft portion 621 from the closed position to the open position while the second path member 32 is connected to the waste liquid introduction port 522. Also, it is possible to prevent the second path member 32 from interfering with the opening / closing lid 62.
　また、既述の通り、キャニスタ６の開閉蓋体６２の天面部６２５において、廃液導入ポート５２２の露出を許容する切欠き部６２３の周辺部分が、切欠き部６２３の端縁から離れるに従い上に傾斜した傾斜部６２５１とされている。これにより、医療従事者（作業者）が、廃液導入ポート５２２に第２経路部材３２を接続する作業を行う際に、開閉蓋体６２の天面部６２５が邪魔となることを抑制し、第２経路部材３２の接続作業の作業性の向上を図ることができる。 Further, as described above, in the top surface portion 625 of the opening / closing lid 62 of the canister 6, the peripheral portion of the notch portion 623 that allows the exposure of the waste liquid introduction port 522 moves upward as the distance from the edge of the notch portion 623 increases. It is said that the inclined portion 6251 is inclined. As a result, when the medical worker (worker) performs the work of connecting the second path member 32 to the waste liquid introduction port 522, the top surface portion 625 of the opening / closing lid 62 is suppressed from becoming an obstacle, and the second It is possible to improve the workability of the connection work of the path member 32.
　また、既述の通り、キャニスタ６の開閉蓋体６２が前記閉塞位置に配置された状態において、上方構造部６１２の第１シール部材６１２６Ａと、開閉蓋体６２の第２シール部材６２４１Ｂとの間に、ライナー５の容器蓋体５２のフランジ部５２１が挟み込まれる。これにより、キャニスタ６内の気密性が保持される。具体的には、キャニスタ６内において、容器本体６１によってライナー５の外側に区画される前記吸引空間Ｓ１と、開閉蓋体６２の凹部６２４２によってライナー５の上方側に区画される前記上方空間Ｓ２とが、気密空間とされる。ここで、前記第１シール部材６１２６Ａと前記第２シール部材６２４１Ｂとの間に挟み込まれる容器蓋体５２のフランジ部５２１は、両シール部材が圧接する圧接部分を有し、当該圧接部分よりも内側に貫通穴５２１１が設けられている。このフランジ部５２１に設けられる貫通穴５２１１は、前記吸引空間Ｓ１と前記上方空間Ｓ２とを連通させる。これにより、吸引源２の吸引力が作用したときには、前記吸引空間Ｓ１及び前記上方空間Ｓ２の両空間が負圧とされる。このように、前記吸引空間Ｓ１及び前記上方空間Ｓ２の両空間が負圧とされることにより、吸引起点部３３から吸引された廃液ＷＬを廃液導入ポート５２２からライナー５の廃液収容空間Ｓ３内に導入することができる。 Further, as described above, in the state where the opening / closing lid 62 of the canister 6 is arranged at the closed position, between the first sealing member 6126A of the upper structure portion 612 and the second sealing member 6241B of the opening / closing lid 62. The flange portion 521 of the container lid 52 of the liner 5 is sandwiched therein. As a result, the airtightness in the canister 6 is maintained. Specifically, in the canister 6, the suction space S1 partitioned outside the liner 5 by the container body 61, and the upper space S2 partitioned above the liner 5 by the recess 6242 of the opening / closing lid 62. However, it is considered to be an airtight space. Here, the flange portion 521 of the container lid 52 sandwiched between the first seal member 6126A and the second seal member 6241B has a pressure contact portion where both seal members are in pressure contact with each other, and is inside the pressure contact portion. Is provided with a through hole 5211. The through hole 5211 provided in the flange portion 521 communicates the suction space S1 with the upper space S2. As a result, when the suction force of the suction source 2 acts, both the suction space S1 and the upper space S2 are subjected to negative pressure. By making both the suction space S1 and the upper space S2 negative pressure in this way, the waste liquid WL sucked from the suction starting point 33 is brought into the waste liquid storage space S3 of the liner 5 from the waste liquid introduction port 522. Can be introduced.
　なお、上述した具体的実施形態には以下の構成を有する発明が主に含まれている。 The specific embodiments described above mainly include inventions having the following configurations.
　本発明の一の局面に係る容器収容器は、吸引源の吸引力によって吸引された所定の廃液を収容する廃液収容容器を収容可能に構成されている。この容器収容器は、上下方向に延びる有底筒状に形成されて上端面部において上方に開口する上方開口を有し、前記廃液収容容器を収容する容器本体と、前記上方開口を塞ぐ閉塞位置と前記上方開口を開放する開放位置との間での変位が可能となるように前記容器本体に支持され、前記閉塞位置に配置された状態において、前記容器本体に収容された前記廃液収容容器の外側に、前記吸引源の吸引力によって負圧とされる吸引空間を前記容器本体と共に形成する開閉蓋体と、前記容器本体又は前記開閉蓋体に形成され、外部空間の空気が前記吸引空間へ流入する流路となる空気流入路と、前記開閉蓋体の開閉を操作する部材であって、前記開閉蓋体が前記閉塞位置に配置された状態を保持する閉塞保持姿勢と、前記開閉蓋体の前記閉塞位置から前記開放位置への変位に応じた前記上方開口の開放を許容する開放許容姿勢との間での姿勢変更が可能となるように、前記容器本体又は前記開閉蓋体に支持された開閉操作部材と、前記空気流入路を閉鎖する流路閉鎖位置と前記空気流入路を開放する流路開放位置との間での、前記開閉操作部材の姿勢変更に応じた移動が可能となるように、前記開閉操作部材に連結された通気弁と、を備える。前記通気弁は、前記開閉操作部材が前記閉塞保持姿勢を取った状態では、前記吸引源の吸引力による前記吸引空間の負圧状態が維持されるように前記流路閉鎖位置に配置され、前記開閉操作部材が前記閉塞保持姿勢から前記開放許容姿勢へと姿勢変更すると、その姿勢変更に応じて前記流路閉鎖位置から前記流路開放位置へと移動することにより、外部空間の空気の前記空気流入路を介した前記吸引空間への流入を許容する。 The container container according to one aspect of the present invention is configured to be capable of accommodating a waste liquid storage container that stores a predetermined waste liquid sucked by the suction force of the suction source. This container container has an upper opening which is formed in a bottomed tubular shape extending in the vertical direction and opens upward at the upper end surface portion, and has a container body for accommodating the waste liquid storage container and a closing position for closing the upper opening. The outside of the waste liquid storage container housed in the container body in a state of being supported by the container body and arranged in the closed position so as to be displaced from the open position for opening the upper opening. In addition, an opening / closing lid that forms a negative pressure by the suction force of the suction source together with the container body, and an opening / closing lid formed in the container body or the opening / closing lid, and air in the external space flows into the suction space. An air inflow path that serves as a flow path, a closing holding posture that is a member that operates the opening and closing of the opening / closing lid and holds the state in which the opening / closing lid is arranged at the closing position, and a closing holding posture of the opening / closing lid. It was supported by the container body or the opening / closing lid so that the posture could be changed from the opening allowable posture that allows the opening of the upper opening according to the displacement from the closed position to the opening position. The opening / closing operation member can be moved between the flow path closing position for closing the air inflow path and the flow path opening position for opening the air inflow path according to the posture change of the opening / closing operation member. Also includes a vent valve connected to the opening / closing operation member. The vent valve is arranged at the flow path closing position so that the negative pressure state of the suction space is maintained by the suction force of the suction source when the opening / closing operation member is in the closed holding posture. When the opening / closing operation member changes its posture from the closed holding posture to the opening allowable posture, the opening / closing operating member moves from the flow path closing position to the flow path opening position in response to the posture change, so that the air in the external space is the air. Allows inflow into the suction space through the inflow path.
　この容器収容器によれば、開閉操作部材が閉塞保持姿勢を取った状態では、開閉蓋体の閉塞位置に配置された状態が保持されると共に、通気弁が空気流入路を閉鎖する流路閉鎖位置に配置される。この状態では、容器収容器の容器本体内において廃液収容容器の外側の吸引空間が密閉空間とされる。この状態で吸引源の吸引力が作用すると前記吸引空間が負圧とされ、これに伴って廃液が廃液収容容器内に流入する。このようにして廃液収容容器内に廃液を収容することができる。 According to this container container, when the opening / closing operation member is in the closed holding posture, the state of being arranged at the closed position of the opening / closing lid is maintained, and the flow path is closed by the vent valve closing the air inflow path. Placed in position. In this state, the suction space outside the waste liquid storage container inside the container body of the container container is a closed space. When the suction force of the suction source acts in this state, the suction space becomes a negative pressure, and the waste liquid flows into the waste liquid storage container accordingly. In this way, the waste liquid can be stored in the waste liquid storage container.
　一方、吸引源の吸引力の作用が停止された状態において、開閉操作部材が閉塞保持姿勢から開放許容姿勢へと姿勢変更すると、その姿勢変更に応じて通気弁が、流路閉鎖位置から空気流入路を開放する流路開放位置へと移動する。これにより、外部空間の空気が空気流入路を介して容器収容器内の吸引空間へ流入し、当該吸引空間が大気開放される。このため、開閉操作部材が開放許容姿勢を取った状態で開閉蓋体を開放するときに、容器収容器内に負圧が残ることを防止することができる。この結果、開閉蓋体を容易に開放することができ、開閉蓋体が開放位置に配置された状態において容器本体に対する廃液収容容器の出し入れが可能となる。 On the other hand, when the opening / closing operation member changes its posture from the closed holding posture to the open allowable posture while the action of the suction force of the suction source is stopped, the ventilation valve inflows air from the flow path closing position in response to the change in posture. Move to the flow path open position to open the road. As a result, the air in the external space flows into the suction space in the container container through the air inflow path, and the suction space is opened to the atmosphere. Therefore, it is possible to prevent negative pressure from remaining in the container container when the opening / closing lid is opened with the opening / closing operation member in the opening allowable posture. As a result, the opening / closing lid can be easily opened, and the waste liquid storage container can be taken in and out of the container body in a state where the opening / closing lid is arranged in the open position.
　上記の容器収容器は、前記容器本体又は前記開閉蓋体に形成され、前記吸引源の吸引力によって前記吸引空間から排出される空気の流路となる空気排出路を、更に備える構成であってもよい。そして、前記空気流入路は、前記空気排出路よりも圧力損失が大きい。 The container container is further provided with an air discharge path formed in the container body or the opening / closing lid and serving as a flow path for air discharged from the suction space by the suction force of the suction source. May be good. The air inflow path has a larger pressure loss than the air discharge path.
　この態様では、吸引源の吸引力によって前記吸引空間内の空気が空気排出路を介して排出されることにより、前記吸引空間が負圧とされる。ここで、外部空間の空気が前記吸引空間へ流入する流路となる空気流入路は、空気排出路よりも圧力損失が大きい。これにより、吸引源の吸引力によって吸引空間内の空気が空気排出路を介して排出されて吸引空間が負圧とされる状態が継続されているときに、開閉操作部材が誤って操作されたとしても、吸引空間の負圧状態が保持されて、閉塞保持姿勢から開放許容姿勢への姿勢変更を抑止することができる。 In this embodiment, the suction force of the suction source causes the air in the suction space to be discharged through the air discharge path, so that the suction space becomes a negative pressure. Here, the air inflow path, which is the flow path through which the air in the external space flows into the suction space, has a larger pressure loss than the air discharge path. As a result, the opening / closing operation member was erroneously operated while the suction force of the suction source caused the air in the suction space to be discharged through the air discharge path and the suction space was kept in a negative pressure state. Even so, the negative pressure state of the suction space is maintained, and the posture change from the closed holding posture to the open allowable posture can be suppressed.
　上記の容器収容器において、前記開閉操作部材は、前記空気流入路を外側から覆うように、前記容器本体に対して取り外しが可能な操作回動軸部回りの回動が可能に当該容器本体に支持されている。この場合、前記通気弁は、前記操作回動軸部よりも内側において前記開閉操作部材の姿勢変更に応じて移動するように前記開閉操作部材に連結され、前記操作回動軸部が前記容器本体から取り外された状態において前記開閉操作部材との連結の解除が可能である構成であってもよい。 In the container container, the opening / closing operation member can rotate around the operation rotation shaft portion that can be removed from the container body so as to cover the air inflow path from the outside. It is supported. In this case, the vent valve is connected to the opening / closing operation member so as to move inside the operation rotation shaft portion in response to a change in the posture of the opening / closing operation member, and the operation rotation shaft portion is connected to the container body. The structure may be such that the connection with the opening / closing operation member can be released in the state of being removed from the.
　この態様では、開閉操作部材が空気流入路を外側から覆うように設けられているので、不用意にゴミ等の異物が空気流入路を介して吸引空間内に進入することを抑制することができる。また、容器本体に対して開閉操作部材を回動可能に支持する操作回動軸部が当該容器本体から取り外された状態において、通気弁は、開閉操作部材との連結の解除が可能である。このような構成では、通気弁を清掃するときや、通気弁を交換するときには、容器本体から操作回動軸部を取り外し、その後、開閉操作部材との連結を解除することにより、通気弁を取り外すことができる。 In this embodiment, since the opening / closing operation member is provided so as to cover the air inflow path from the outside, it is possible to prevent foreign matter such as dust from inadvertently entering the suction space through the air inflow path. .. Further, the ventilation valve can be released from the connection with the opening / closing operation member in a state where the operation rotation shaft portion that rotatably supports the opening / closing operation member with respect to the container body is removed from the container body. In such a configuration, when cleaning the ventilation valve or replacing the ventilation valve, the operation rotation shaft portion is removed from the container body, and then the connection with the opening / closing operation member is released to remove the ventilation valve. be able to.
　本発明の他の局面に係る廃液貯留器は、吸引源の吸引力によって吸引された所定の廃液を貯留可能であって、筒体と当該筒体の上端に接合された容器蓋体とを含み、前記廃液を収容する廃液収容空間を区画する廃液収容容器と、前記廃液収容容器を収容する、上記の容器収容器と、を備える。 The waste liquid reservoir according to another aspect of the present invention can store a predetermined waste liquid sucked by the suction force of the suction source, and includes a cylinder and a container lid joined to the upper end of the cylinder. A waste liquid storage container for partitioning a waste liquid storage space for storing the waste liquid, and the container container for storing the waste liquid storage container are provided.
　上記の廃液貯留器において、前記廃液収容容器は、前記容器蓋体に設けられ、前記容器収容器の前記吸引空間が負圧とされることに応じて前記廃液を、前記廃液収容空間内に導入する廃液導入ポートを有する。また、前記容器収容器において前記開閉蓋体は、前記上下方向と直交する方向に延びる蓋体回動軸部回りの回動によって前記閉塞位置と前記開放位置との間で変位するように構成され、前記蓋体回動軸部が取り付けられる軸取付部と、前記開閉蓋体の外周縁から中心に向かって内側に切り欠かれ、前記開閉蓋体が前記閉塞位置に配置された状態において、前記廃液収容容器の前記廃液導入ポートの露出を許容する切欠き部と、を有する。そして、前記軸取付部と前記切欠き部とは、前記開閉蓋体の中心を対称点とする点対称な位置関係にある構成であってもよい。 In the above waste liquid storage device, the waste liquid storage container is provided on the container lid, and the waste liquid is introduced into the waste liquid storage space in response to the negative pressure of the suction space of the container container. Has a waste liquid introduction port. Further, in the container container, the opening / closing lid is configured to be displaced between the closed position and the open position by rotation around the lid rotation shaft portion extending in a direction orthogonal to the vertical direction. In a state where the shaft mounting portion to which the lid rotating shaft portion is mounted and the opening / closing lid body are notched inward from the outer peripheral edge toward the center and the opening / closing lid body is arranged at the closed position, the above. It has a notch portion that allows exposure of the waste liquid introduction port of the waste liquid storage container. The shaft mounting portion and the notch portion may have a point-symmetrical positional relationship with the center of the opening / closing lid as a symmetric point.
　この態様では、容器収容器に収容される廃液収容容器の容器蓋体には、廃液導入ポートが設けられている。この廃液導入ポートには、例えば、廃液の吸引起点となる吸引起点部から廃液貯留器に至る吸引経路を構成する可撓性チューブ等の経路部材が、接続される。廃液導入ポートに前記経路部材が接続された状態で、吸引源の吸引力によって容器収容器内の吸引空間が負圧とされることにより、吸引起点部から吸引された廃液を廃液導入ポートから廃液収容容器内に導入することができる。また、容器収容器の開閉蓋体において、蓋体回動軸部が取り付けられる軸取付部と、廃液導入ポートの露出を許容する切欠き部とは、開閉蓋体の中心を対称点とする点対称な位置関係にある。これにより、廃液導入ポートに接続された経路部材の位置を、開閉蓋体が蓋体回動軸部回りに回動したときの切欠き部の回動軌跡から外れた位置に設定することが、容易となる。このため、廃液導入ポートに経路部材が接続された状態のままで、開閉蓋体が閉塞位置から開放位置に向かって蓋体回動軸部回りに回動したとしても、経路部材が開閉蓋体に干渉することを抑制することができる。 In this aspect, the waste liquid introduction port is provided on the container lid of the waste liquid storage container housed in the container container. A path member such as a flexible tube forming a suction path from the suction starting point, which is the suction starting point of the waste liquid, to the waste liquid reservoir is connected to the waste liquid introduction port. With the path member connected to the waste liquid introduction port, the suction force of the suction source creates a negative pressure in the suction space inside the container container, so that the waste liquid sucked from the suction starting point is drained from the waste liquid introduction port. It can be introduced into the storage container. Further, in the opening / closing lid of the container container, the shaft mounting portion to which the lid rotating shaft portion is attached and the notch portion that allows the exposure of the waste liquid introduction port have a symmetrical point at the center of the opening / closing lid. There is a symmetrical positional relationship.
